    Virtual Modeling for Lifecycle Performance Assessment in aerospace design2016In: Product-Service Systems across Life Cycle / [ed] Cavalieri, S; Ceretti, E; Tolio, T; Pezzotta, G, Elsevier, 2016, Vol. 47, p. 335-340Conference paper (Refereed)
    Abstract [en]

    The aim of the paper is to present an approach for the multidisciplinary evaluation of alternative modular concepts in preliminary design with the intent of enhancing engineers’ capability to simulate alternative scenarios with different design configurations, so to derive decisions about the most valuable design concepts to further develop. The research contribution is novel in the way that it expands the Set-Based-Engineering approach by addressing the “servitization” challenge in two ways: firstly by the use of value models and sustainability models as decision making support, making possible a preliminary assessment of the value contribution and of the sustainability performances of a design concept;secondly, by the use of functional modelling modules and configurable systems elements for platform-based design, to manage the  complex relationships within and between parts of the platform throughout the lifecycle. The paper presents the main features of the approach and introduces an industrial case concerning the development of a module component for an aircraft engine in which the approach is applied for demonstration. The paper finally elaborates on the benefits and implications of the approach in the design process.

    Value-driven product service systems development: Methods and industrial applications2016In: CIRP - Journal of Manufacturing Science and Technology, ISSN 1755-5817, E-ISSN 1878-0016, Vol. 15, p. 42-55Article in journal (Refereed)
    Abstract [en]

    In recent times a service-dominant logic is permeating the design of complex systems. However, in spite of their appeal, initiatives such as Product Service Systems (PSS) have not become mainstream, and methods are lacking to support this transition. This paper argues that methodological guidance, as well as tools for decision support, may be found in the research field of Value Driven Design (VDD), which originates in the realm of Systems Engineering. The paper objective is to elaborate on gaps and opportunities for cross-pollination between VDD and PSS. The results of a systematic review of methods and tools for design decision support highlight the opportunity for introducing optimization models derived from VDD in the PSS design process, while the latter can enrich VDD research with a more qualitative value assessment logic. The paper summarizes this integration in a methodological approach, and exemplifies its application in case studies mainly from the aerospace and road construction equipment sector.

    Introducing Sustainability in Value Models to Support Design Decision Making: A Systematic Review2017In: Sustainability, ISSN 2071-1050, E-ISSN 2071-1050, Vol. 9, no 6, article id 994Article in journal (Refereed)
    Abstract [en]

    Manufacturing organizations shall recognize sustainability as a business occasion to capitalize on, rather than an undesirable pressing situation. Still, empirical evidence shows that this opportunity is hard to capture and communicate in global strategic decisions, through planning by tactical management, to daily operational activities. This paper systematically reviews the modeling challenges at the crossroad of value and sustainability decisions making, spotlighting methods and tools proposed in literature to link sustainability to customer value creation at strategic, tactical and operational level. While statistical results show that the topic of sustainability and value modeling is trending in literature, findings from content analysis reveal that recent attempts to promote a value-based view in the sustainability discussion remain at a strategic level, with most of the proposed indicators being suited for managerial decision-making. The lack of support at operational level points to the opportunity of cross-pollinating sustainability research with value-centered methodologies originating from the aerospace sector. The Value Driven Design framework is proposed as main hub from which to derive models supporting engineers and technology developers in the identification of win-win-win situations, where sustainable improvements are aligned with business advantages.

    Models for Value-driven engineering design2016In: Proceedings of the International Design Conference / [ed] Marjanovic, D; Storga, M; Bojcetic, N; Skec, S, DESIGN SOC, UNIV STRATHCLYDE , 2016Conference paper (Refereed)
    Abstract [en]

    Nowadays, it is a great challenge to understand what models shall be used to iteratively translate customer desires into terms that are meaningful for engineering design decision-making. This paper proposes a framework illustrating the iterative evolution of model-based enablers for value during conceptual system design. The framework is developed from the analysis of four case studies in the Swedish manufacturing industry. The paper discusses the learning from the cross-case study, and elaborates on how value models may complement existing Systems Engineering practices.

    Nonlinear Quality Function Deployment: an experimental analysis2017Conference paper (Refereed)
    Abstract [en]

    Quality Function Deployment (QFD) is a common model to frontload engineering design activities with, linking the characteristics of a product vs. the voice of the customer using linear relationships. This approximation is often claimed to be misleading when dealing with the design of complex engineering systems. The paper presents the results of experimental activities aimed at verifying usability and effectiveness of nonlinear functions as extension of the QFD logic. A total of 40 experiments was conducted in a given design episode, involving 139 participants, to analyse the trade-off between the benefit of introducing nonlinearity vs. effort and cost triggered by increased complexity in the modelling. The results show that nonlinear functions, while improving the granularity of the QFD mapping, keeps the method simple enough to work as ‘boundary object’ in cross-functional design teams, irrespectively from the experience of design team members. The experiments also highlight how users’ cognitive attention in the task is dependent from the format by which nonlinear merit functions are presented.

    Knowledge Enabled Engineering2015In: International Workshop of Advanced Manufacturing and Automation, Trans Tech Publications Inc., 2015Conference paper (Refereed)
    Abstract [en]

    The development of complex product-service combinations challenges the existing practices for engineering knowledge management. The objective of the paper is to highlight how such practices need to change to meet the engineers’ demand for knowledge when developing “functions” instead of merely hardware. It further proposes Knowledge Enabled Engineering (KEE) as an umbrella term that collects engineering knowledge management methods and tools inspired by the second wave of knowledge management, and that are aimed to meet needs of today’s modern knowledge workers in engineering organizations. The current state of readiness of these approaches is eventually described together with results from verification and validation activities.

    EVOKE: A Value-Driven Concept Selection Method for Early System Design2018In: Journal of Systems Science and Systems Engineering, ISSN 1004-3756, E-ISSN 1861-9576, Vol. 27, no 1, p. 46-77Article in journal (Refereed)
    Abstract [en]

    The development of new technologically advanced products requires the contribution from a range of skills and disciplines, which are often difficult to find within a single company or organization. Requirements establishment practices in Systems Engineering (SE), while ensuring coordination of activities and tasks across the supply network, fall short when it comes to facilitate knowledge sharing and negotiation during early system design. Empirical observations show that when system-level requirements are not available or not mature enough, engineers dealing with the development of long lead-time sub-systems tend to target local optima, rather than opening up the design space. This phenomenon causes design teams to generate solutions that do not embody the best possible configuration for the overall system. The aim of this paper is to show how methodologies for value-driven design may address this issue, facilitating early stage design iterations and the resolution of early stage design trade-offs. The paper describes how such methodologies may help gathering and dispatching relevant knowledge about the ‘design intent’ of a system to the cross-functional engineering teams, so to facilitate a more concurrent process for requirement elicitation in SE. The paper also describes EVOKE (Early Value Oriented design exploration with KnowledgE maturity), a concept selection method that allows benchmarking design options at sub-system level on the base of value-related information communicated by the system integrators. The use of EVOKE is exemplified in an industrial case study related to the design of an aero-engine component. EVOKE’s ability to raise awareness on the value contribution of early stage design concepts in the SE process has been further verified with industrial practitioners in ad-hoc design episodes.

    Model-driven value assessment: a case from the food packaging industry2018In: Proceeedings of the International DESIGN Conference / [ed] D. Marjanović, M. Štorga, S. Škec, N. Bojčetić, N. Pavković (eds.), The Design Society, 2018, Vol. 1, p. 161-170Conference paper (Refereed)
    Abstract [en]

    Consumer perception of food packaging solutions is driven by early design decisions on paperboard configuration and manufacturing technologies. Simulation Driven Design is common to frontload design activities, but is confined to the engineering field and fails to capture higher-level value aspects. This paper presents an assessment framework connecting customer value dimensions with simulations conducted on the mechanical properties of the packaging material, and discusses how value modelling results can be visualised to support collaborative decision making in cross-functional teams.

    A model-based approach for sustainability and value assessment in the aerospace value chain2015In: Advances in Mechanical Engineering, ISSN 1687-8132, E-ISSN 1687-8140, Vol. 7, no 6, p. 1-19Article in journal (Refereed)
    Abstract [en]

    In the aerospace industry, systems engineering practices have been exercised for years, as a way to turn high-level design objectives into concrete targets on system functionality (e.g. range, noise, and reliability). More difficult is to decompose and clarify sustainability implications in the same way and to compare them against performance-related capabilities already during preliminary design. This article addresses the problem of bringing the important—yet typically high level and complex—sustainability aspects into engineering practices. It proposes a novel integrated model-based method that provides a consistent way of addressing the well-known lack of generic and integrated ways of clarifying both cost and value consequences of sustainability in early phases. It further presents the development and implementation of such approach in two separate case studies conducted in collaboration with a major aero-engine sub-system manufacturer. The first case concerns the assessment of alternative business configurations to maintain scarce materials in closed loops, while the second one concerns the production technology of an aero-engine component. Eventually, this article highlights the learning generated by the development and implementation of these approaches and discusses opportunities for further development of model-based support.

    Value-driven engineering design: lessons learned from the road construction equipment industry2017In: Proceedings of the International Conference on Engineering Design, ICED / [ed] Maier A.M.,Skec S.,Salustri F.A.,Fadel G.,Kim H.,Kokkolaras M.,Oehmen J.,Van der Loos M., The Design Society, 2017, Vol. 1, p. 319-328, article id DS87-1Conference paper (Refereed)
    Abstract [en]

    Value models, in form of economical optimization functions, are often proposed to frontload engineering design activities. However, literature argues that, when qualitative data and assumptions prevail, a qualitative assessment of the ‘goodness’ of a design is preferable against a numerical (and monetary-based) encoding of preferences. This paper explores how a model-based approach can support deliberation about value in cross-functional design teams. Emerging from case studies in the road compaction equipment industry, the paper analyzes preferences for value modelling support when it comes to iteratively translate customer desires into terms meaningful for engineering design decision-making. It further prescribes a framework for value-driven engineering design that considers the need to update the value model definition as far as new information become available in the process, moving from qualitative to quantitative. The findings highlight the role the proposed chain of value models plays in terms of providing a shared reference to stimulate value discussions across functions and organizational roles, which is something that does not naturally happen in the organization today.

    Boundary objects for PSS design2016In: PRODUCT-SERVICE SYSTEMS ACROSS LIFE CYCLE / [ed] Cavalieri, S; Ceretti, E; Tolio, T; Pezzotta, G, Elsevier, 2016, Vol. 47, p. 329-334Conference paper (Refereed)
    Abstract [en]

    In PSS design, hardware and service developers often have different objectives. Lacking to communicate and negotiate them across boundaries might lead to solutions unable to generate market shares and long-term profitability. This paper aims to contribute to the definition of ‘boundary objects’ that facilitate the sharing of knowledge between members of cross-functional teams engaged in PSS conceptual design activities. Empirical data are gathered from three case studies in the Swedish manufacturing industry to reveal how servitization affects early stage design decision-making, and how hardware vs. service trade-offs are negotiated and solved. The analysis of the findings points to four main trends to be considered when designing such objects in the realm of PSS. These are: an underlying model-based logic, the use of metrics based on customer value, the ability to quickly generate and assess scenarios, the use of non linear relationships to map PSS features vs. customer value.

    A systematic review of value metrics for PSS design2017In: Procedia CIRP, 2017, Vol. 64, p. 289-294Conference paper (Refereed)
    Abstract [en]

    The notion of ‘value’ has become pivotal in the PSS domain, with a plethora of ‘indicators’, ‘drivers’ and ‘measurements’ proposed to guide the assessment of PSS concepts across the design process. This paper presents the results of a systematic literature review that maps existing contributions dealing with metrics for PSS value in early design. The findings reveal the lack of a common taxonomy to define what PSS value is, as well as differences in terms of granularity of the applied metrics, which span from very generic to highly case-study specific. This mapping aims at validating a proposed classification framework for such metrics, which balances customer and provider value perspectives in early stage PSS concept assessment activities. Its goal is to raise the cross-functional design team awareness on the multiple value types impacted by early stage design decisions when working with MADM matrixes; hence to highlight opportunities for improvement, recombination and refinement.

    Model Driven Decision Arena: an aerospace study2018In: Proceedings of the International Design Conference / [ed] D. Marjanović, M. Štorga, S. Škec, N. Bojčetić, N. Pavković (eds.), The Design Society, 2018, Vol. 1, p. 171-182Conference paper (Refereed)
    Abstract [en]

    The concept of Decision Theatre (DT) is of great interest to leverage knowledge sharing in early stage design decision events. Yet, few contributions show how to configure a DT to support design space exploration and concept selection in cross-functional teams. This paper describes the development of a model-driven decision arena (MDDA) for aero-engine sub-system design. After presenting the descriptive study findings, it illustrates the overall logic of the MDDA environment and exemplifies its use in a case study related to the design of a turbine real structure (TRS) for commercial use.

    Simplicity of skew inverse semigroup rings with applications to Steinberg algebras and topological dynamics2018In: Forum mathematicum, ISSN 0933-7741, E-ISSN 1435-5337Article in journal (Refereed)
    Abstract [en]

    Given a partial action π of an inverse semigroup S on a ring A {\mathcal{A}}, one may construct its associated skew inverse semigroup ring A π S {\mathcal{A}\rtimes-{\pi}S}. Our main result asserts that, when A {\mathcal{A}} is commutative, the ring A π S {\mathcal{A}\rtimes-{\pi}S} is simple if, and only if, A {\mathcal{A}} is a maximal commutative subring of A π S {\mathcal{A}\rtimes-{\pi}S} and A {\mathcal{A}} is S-simple. We apply this result in the context of topological inverse semigroup actions to connect simplicity of the associated skew inverse semigroup ring with topological properties of the action. Furthermore, we use our result to present a new proof of the simplicity criterion for a Steinberg algebra A R (g) {A-{R}(\mathcal{G})} associated with a Hausdorff and ample groupoid g {\mathcal{G}}. © 2018 Walter de Gruyter GmbH, Berlin/Boston.

    LOW DELAY VIDEO TRANSCODING SERVICES ON DISTRUBUTED COMPUTING PLATFORM.2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The demand of digital video with higher resolution is increasing everyday and in amodern world the videos are consumed in all kinds of multimedia devices. The transmissionof higher quality videos over the internet require higher bandwidth, which isnot an acceptable option. So, it is necessary to compress the video to a compact file byremoving redundancies and detail information.

    The process of compressing a video file requires a lot of complex calculations,which is a time consuming process, specially for live telecasting or real-time videoconferencing. In addition videos with higher quality such as higher number of Frameper Second (FPS) or higher resolution like HD and 4k video requires huge redundantdata processing. Hence, this operation causes delays during the video playback. Tominimize the time delay for the video coding, there are coding methods such as losslessand lossy coding which has been around for a long time. However, the idea to increasethe number of processing unit like CPUs and memory for video coding software is anarea that require further research to improve coding techniques.

    Distributed system uses available resources in the network to achieve a commongoal. It explores the available infrastructure so that the task can be done in parallel. Cloud computing is a great example of distributed system which has fully dedicatedresources for such complex jobs.

    This thesis deals with these areas in real-time to lower the video coding delaythrough investigating distributed resources as well as the parallelization in video codingstandards such as AVC and HEVC. It has been carried out with a collaborationwith Ericsson Research in Stockholm.

    An analysis of cloud based e-learning providers’ versioning strategy2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: Versioning is a product differentiation strategy where a product or service are distinguished or diversified in the intention of making it more attractive to a specific target group. It is often used to price discriminate and a way to profit maximize. Previous studies have mostly concerned software products in general. But with cloud based software products, specific conditions when versioning might occur. E-learning system are one specific software product that shifts more and more to the cloud and a specific market to study.

    Purpose: Differentiating a software product can be made in several ways but which features to use when versioning is not studied in previous studies, the conditions and reasons are unclear. The purpose of this study is to study cloud based e-learning providers to discover characteristics of feasible features when versioning.

    Method: To answer the defined research problem qualitative research methods was used in terms of interviews, documentations and observing artefacts. The research data was gathered through four case studies of different cloud e-learning provider, conducting of eight interviewees and four observations of their respective e-learning system. Additionally, articles and other documents was also analysed, that was provided by the companies of the case studies.

    Delimitations: This research was restricted so it focused on cloud e-learning providers’ perspective as they are those who use the versioning strategy. The limitations therefore only concerns e-learning and cloud services and are not generalized to all software products.

    Results: The results from the different data collection methods shows that feature characteristics mainly concerns market reasons with specific user preferences and customers with buying behaviors. E-learning systems brings technical reasons to why features are feasible, and the cloud have different service layers, each with different possible features to differentiate in. Costs is also a major concern when choosing feasible features for versioning.

    Conclusion: E-learning providers see the versioning strategy as an iterative process. Which features that are feasible for one versions seem to change over time as the market changes and product develops. Features are mainly related to the specific market. When versioning, features are separated between standard features for the whole system or segment specific features for one version. Features are also considered if they will add more value than the cost to develop. E-learning providers also develop features if they are economic and technological possible to develop, and if they are within the company’s scope.

    Bullerproblematiken vid planering och byggande av bostäder2014Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [sv]

    Dagens planeringsideal innebär en hållbar stadsbyggnad som skapas genom förtätning och blandning av funktioner och trafikslag. Den täta staden argumenteras skapa möjligheter för människan att leva hållbart då bostäder, service och arbete finns inom korta avstånd. Däremot finns det ett annat perspektiv, genom att förtäta och blanda funktioner blir även störningarna i samhället större. En av dessa störningar är buller, som de senare åren har fått stark uppmärksamhet då det kopplats till många hälsoproblem. Målen med den täta staden och buller är inte förenliga. Från statligt håll har bullerfrågan fått stor uppmärksamhet de senare åren då bullerreglerna idag ses som ett hinder för bostadsbyggandet. Med grund i detta har förslag på nya regler genom en bullerutredning samt en efterföljande proposition kommit ut. Syftet med denna studie är att dels studera, och förstå motiven bakom, de förändringar som är föreslagna i lagstiftningen avseende buller i planering och byggande, dels att studera vilka konsekvenser förändringarna kan få för den svenska planeringspraktiken. Studien är indelad i två delar. I den första delen analyseras dokument som under de senaste åren har varit av vikt i diskussionen om hur buller bör hanteras vid planering och byggande av bostäder. I den andra delen har en fallstudie genomförts. Tre detaljplaneärenden från olika kommuner och där buller-problematiken har varit ett centralt tema har studerats. Intervjuer har även genomförts med handläggande planarkitekter. Genom analysen som baseras på det teoretiska perspektivet rörande governance och plan- och byggparadigmen, har en problematik belysts som till stor del beror på olika sätt att se på styrning. Det finns allt fler aktörer inblandade i diskussionen, vars intressen står i konflikt med varandra. En förklaring till den problematik som finns är att det idag finns två sätt att se på styrning av mark och vatten, ett där miljön och bevarande, och ett där planering och förändring, står i fokus. Intervjuade tjänstemän ser en stor problematik idag, som anser att reglerna är otydliga och att länsstyrelsen är hårda i sina bedömningar. Detaljplanerna som studeras belyser även denna problematik där länsstyrelserna har varit i stor diskussion med kommunerna om bullerhanteringen. En av de största frågorna är kommunernas möjlighet att göra avsteg från riktvärdena. Handläggarna vill att alla kommuner ska ha samma möjligheter till avsteg, men reglerna idag innefattar enbart större tätorter. Om reglerna som föreslås blir verklighet hoppas kommunerna att konsekvensen blir en enklare planprocess och att möjligheterna till planering i bullerstörda miljöer blir större.

    Target Classification in Perimeter Protection with a Micro-Doppler Radar2016In: 2016 17TH INTERNATIONAL RADAR SYMPOSIUM (IRS), 2016Conference paper (Refereed)
    Abstract [en]

    In security surveillance at the perimeter of critical infrastructure, such as airports and power plants, approaching objects have to be detected and classified. Especially important is to distinguish between humans, animals and vehicles. In this paper, micro-Doppler data (from movement of internal parts of the target) have been collected with a small radar of a low complexity and cost-effective type. From time-velocity diagrams of the data, some physical features have been extracted and used in a support vector machine classifier to distinguish between the classes "human", "animal" and "man-made object". Both the type of radar and the classes are suitable for perimeter protection. The classification result are rather good, 77% correct classification. Particularly interesting is the surprisingly good ability to distinguish between humans and animals. This also indicates that we can choose to have limitations in the radar and still solve the classification task.

    Features for micro-Doppler based activity classification2015In: IET radar, sonar & navigation, ISSN 1751-8784, E-ISSN 1751-8792, Vol. 9, no 9, p. 1181-1187Article in journal (Refereed)
    Abstract [en]

    Safety and security applications benefit from better situational awareness. Radar micro-Doppler signatures from an observed target carry information about the target's activity, and have potential to improve situational awareness. This article describes, compares, and discusses two methods to classify human activity based on radar micro-Doppler data. The first method extracts physically interpretable features from the time-velocity domain such as the main cycle time and properties of the envelope of the micro-Doppler spectra and use these in the classification. The second method derives its features based on the components with the most energy in the cadence-velocity domain (obtained as the Fourier transform of the time-velocity domain). Measurements from a field trial show that the two methods have similar activity classification performance. It is suggested that target base velocity and main limb cadence frequency are indirect features of both methods, and that they do often alone suffice to discriminate between the studied activities. This is corroborated by experiments with a reduced feature set. This opens up for designing new more compact feature sets. Moreover, weaknesses of the methods and the impact of non-radial motion are discussed.

    Mäns upplevelser av att leva med prostatacancer ur ett livsvärldsperspektiv: En litteraturstudie baserad på patografier2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund:  Prostatacancer är den vanligaste cancerformen bland män och drabbar cirka 10 000 personer i Sverige varje år. Prostatacancer ger initialt inga eller diffusa symtom vilket gör denna sjukdom svår att upptäcka. Det finns ett flertal olika behandlingsformer att tillgå vilka skiljer sig beroende på vilket stadie cancern befinner sig i. Sjuksköterskans uppgift är bland annat att bidra med ett personcentrerat arbetssätt för att stödja mannen i dennes nya livssituation. Litteraturstudien förankras i Dahlbergs livsvärldsteori.

    Syfte: Syftet med studien var att ur ett livsvärldsperspektiv beskriva mäns upplevelser av att leva med prostatacancer efter påbörjad behandling.

    Metod: Metoden har grundat sig i en kvalitativ litteraturstudie baserad på narrativer i form av fyra patografier. Elo och Kyngäs beskrivning av en deduktiv innehållsanalys tillämpades som analysmetod. I analysen identifierades utsagor som kodades och delades in i livsvärldsteorins centrala begrepp vilket utgör resultatets fyra huvudkategorier: Den levda kroppen, vårdrelation, lidande samt välbefinnande.

    Resultat: Män som drabbats av prostatacancer upplevde huvudsakligen en påverkan på den levda kroppen, det vill säga fysiskt, psykiskt och existentiellt. Information och stöd från både anhöriga och vårdpersonal hade en viktig inverkan under behandlingstiden. I resultatet framkom det att inkontinens, sexuell dysfunktion och en vilja av att leva i nuet var tre centrala fynd i denna studie. Det ansågs även viktigt att ha goda relationer och lidande tog sig i uttryck både som ett sjukdoms- livs och vårdlidande. Män som drabbats av prostatacancer kunde emellertid uppleva stunder av välbefinnande.

    Slutsats: Resultatet av studien kan ge sjuksköterskan ökad förståelse för mäns upplevelser av att leva med prostatacancer vid påbörjad behandling och hur männen därmed kan stödjas i denna process.

    Clutter Properties for a Side-Looking Radar with Planar Regular and Irregular Subarrays2015In: 2015 16TH INTERNATIONAL RADAR SYMPOSIUM (IRS), 2015, p. 730-735Conference paper (Refereed)
    Abstract [en]

    The effect of the subarray design in a side-looking moving radar with a planar antenna on some clutter properties which are important for suppressing the clutter with STAP (Space-Time Adaptive Processing) is investigated by simulations. These properties are interference DOA Doppler Spectrum (DDS) and clutter rank. The conclusions from the work is that irregular antennas give less clutter in the DDS and that larger subarrays give lower clutter rank.

    Signal Processing for Radar with Array Antennas and for Radar with Micro-Doppler Measurements2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Radar (RAdio Detection And Ranging) uses radio waves to detect the presence of a target and measure its position and other properties. This sensor has found many civilian and military applications due to advantages such as possible large surveillance areas and operation day and night and in all weather. The contributions of this thesis are within applied signal processing for radar in two somewhat separate research areas: 1) radar with array antennas and 2) radar with micro-Doppler measurements.

    Radar with array antennas: An array antenna consists of several small antennas in the same space as a single large antenna. Compared to a traditional single-antenna radar, an array antenna radar gives higher flexibility, higher capacity, several radar functions simultaneously and increased reliability, and makes new types of signal processing possible which give new functions and higher performance.

    The contributions on array antenna radar in this thesis are in three different problem areas. The first is High Resolution DOA (Direction Of Arrival) Estimation (HRDE) as applied to radar and using real measurement data. HRDE is useful in several applications, including radar applications, to give new functions and improve the performance. The second problem area is suppression of interference (clutter, direct path jamming and scattered jamming) which often is necessary in order to detect and localize the target. The thesis presents various results on interference signal properties, antenna geometry and subarray design, and on interference suppression methods. The third problem area is measurement techniques for which the thesis suggests two measurement designs, one for radar-like measurements and one for scattered signal measurements.

    Radar with micro-Doppler measurements: There is an increasing interest and need for safety, security and military surveillance at short distances. Tasks include detecting targets, such as humans, animals, cars, boats, small aircraft and consumer drones; classifying the target type and target activity; distinguishing between target individuals; and also predicting target intention. An approach is to employ micro-Doppler radar to perform these tasks. Micro-Doppler is created by the movement of internal parts of the target, like arms and legs of humans and animals, wheels of cars and rotors of drones.

    Using micro-Doppler, this thesis presents results on feature extraction for classification; on classification of targets types (humans, animals and man-made objects) and human gaits; and on information in micro-Doppler signatures for re-identification of the same human individual. It also demonstrates the ability to use different kinds of radars for micro-Doppler measurements. The main conclusion about micro-Doppler radar is that it should be possible to use for safety, security and military surveillance applications.

    Three-Dimensional DPCA with Rotating Antenna for Clutter Cancellation2015In: 2015 IEEE Radar Conference (RadarCon), Institute of Electrical and Electronics Engineers (IEEE), 2015, p. 1579-1583Conference paper (Refereed)
    Abstract [en]

    In moving radar, e.g. airborne radar, the clutter from land and sea needs to be suppressed in order to detect the target. One approach to total cancellation of the clutter is Displaced Phase Center Antenna (DPCA). DPCA assumes that the antenna elements are positioned on a line parallel to the velocity vector of the radar platform so that the elements can take each others positions at different points of times. In a previous paper we saw that it is possible with other antenna element positions, e.g. in three dimensions, for a total cancellation of the clutter. We arrived at a theoretical condition for this. In this new paper we extend the condition with rotating array antennas. We also formulate an optimization problem for, besides the clutter cancellation, also maximizing the target signal.

    Measurement of Rank and Other Properties of Direct and Scattered Signals2016In: International Journal of Antennas and Propagation, ISSN 1687-5869, E-ISSN 1687-5877, Vol. 2016, article id 5483547Article in journal (Refereed)
    Abstract [en]

    We have designed an experiment for low-cost indoor measurements of rank and other properties of direct and scattered signals with radar interference suppression in mind. The signal rank is important also in many other applications, for example, DOA (Direction of Arrival) estimation, estimation of the number of and location of transmitters in electronic warfare, and increasing the capacity in wireless communications. In real radar applications, such measurements can be very expensive, for example, involving airborne radars with array antennas. We have performed the measurements in an anechoic chamber with several transmitters, a receiving array antenna, and a moving reflector. Our experiment takes several aspects into account: transmitted signals with different correlation, decorrelation of the signals during the acquisition interval, covariance matrix estimation, noise eigenvalue spread, calibration, near-field compensation, scattering in a rough surface, and good control of the influencing factors. With our measurements we have observed rank, DOA spectrum, and eigenpatterns of direct and scattered signals. The agreement of our measured properties with theoretic and simulated results in the literature shows that our experiment is realistic and sound. The detailed description of our experiment could serve as help for conducting other well-controlled experiments. © Copyright 2016 Svante Björklund et al.

    Fast-Time and Slow-Time Space-Time Adaptive Processing for Bistatic Radar Interference Suppression2015In: 2015 IEEE INTERNATIONAL RADAR CONFERENCE (RADARCON), IEEE Communications Society, 2015, p. 674-678Conference paper (Refereed)
    Abstract [en]

    In bistatic radar with transmitter and receiver geographically separated the interference from ground clutter and the direct path signal transmitter-receiver will be strong and must be suppressed in order to detect the target. We apply FT-STAP (Fast-Time Space Time Adaptive Processing) to the suppression, which is unusual, and compare with conventional ST-STAP (Slow-Time STAP) by simulations in order to see whether FT-STAP is an alternative to ST-STAP. The performance of FT-STAP is much worse than of ST-STAP. We give an explanation for this, which also may be the basis for large improvements of FT-STAP. Moreover, we suggest two new performance measures.

    A three-dimensional displaced phase center antenna condition for clutter cancellation2014In: Proceedings of the IEEE Sensor Array and Multichannel Signal Processing Workshop, IEEE , 2014, p. 305-308Conference paper (Refereed)
    Abstract [en]

    In moving radar, e.g. airborne radar, the clutter from land and sea needs to be suppressed in order to detect the target. One approach to total cancellation of the clutter is Displaced Phase Center Antenna (DPCA). DPCA assumes that the antenna elements are positioned on a line parallel to the velocity vector of the radar platform so that the elements can take each others positions at different points of times. This paper theoretically investigates if it is possible with other antenna element positions, e.g. in three dimensions, for a total cancellation of the clutter. We arrive at a condition which conforms to the principle that the elements should take each others positions at different times but allows other antennas than the single line parallel to the velocity vector. Our condition could be used as constraints in an optimization problem where the target signal performance is optimized. The multipulse DPCA condition is one solution to our condition.We also give two examples of non-linear antennas fulfilling our condition.

    Micro-doppler classification with boosting in perimeter protection2017In: IET Conference Publications, Institution of Engineering and Technology , 2017, no CP728Conference paper (Refereed)
    Abstract [en]

    In security surveillance at the perimeter of critical infrastructure, such as airports and power plants, approaching objects have to be detected and classified. Especially important is to distinguish between humans, animals and vehicles. In this paper, micro-Doppler data (from movement of internal parts of the target) have been collected with a small radar. From time-velocity diagrams of the data, physical features have been extracted and used in a Boosting classifier to distinguish between the classes "human", "animal" and "man-made object". This type of classifier has received much attention lately, but not in radar micro-Doppler classification. The classification result on the current data reaches 90% correct classification with this classifier. The ability to distinguish between humans and animals is good on this data. This classifier type gives insight into the classifier and the utilized features, and is easy to use. A comparison with a SVM (Support Vector Machine) classifier, which is common for micro-Doppler, has also been performed. © 2017 Institution of Engineering and Technology. All rights reserved.

    Upplevelser av livsstilsförändringar hos personer med övervikt eller fetma: En litteraturstudie2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Övervikt och fetma är ett växande problem som ökar över hela världen och anses vara en förändringsbar riskfaktor, vilket innebär att de följdsjukdomar som kan drabba en person som en direkt följd av övervikt eller fetma till stora delar skulle kunnat undvikas genom förändrade levnadsvanor. Förändringsprocessen hos en person kan starta först då personen börjar ifrågasätta sina levnadsvanor. Huruvida en livsstilsförändring är möjlig att genomföra handlar inte enbart om egna uppfattningar om beteendet utan även om hur redo personen är att genomföra en förändring.

    Syfte: Syftet med studien var att beskriva vuxna personers upplevelser vid genomförandet av livsstilsförändringar vid övervikt eller fetma.

    Metod: Litteraturstudie med kvalitativ design som är baserad på 13 vetenskapliga artiklar. Analysen utfördes på manifest nivå med hjälp av Graneheim och Lundmans beskrivning av innehållsanalys.

    Resultat: Ur resultatet framkom kategorierna Upplevelse av att socialt stöd är av betydelse, Attityder och inställning påverkar genomförandet av livsstilsförändring, Personliga insikter har betydelse, Upplevelser av att motgångar kan påverka processen av livsstilsförändringar och Motivation kan erhållas på olika sätt. Resultatet visade att behovet av stöd från omgivning och att samtala med människor i liknande situation var av stor betydelse. Att möta fördomar visade sig vara problematiskt för en del. För att komma vidare i sin förändringsprocess hade personliga insikter stor betydelse och det förekom även upplevelser av motgångar i vardagen hos personer som påverkade livsstilsförändringen. Genom upplevelsen att hitta sig själv kunde personen skapa sig samt upprätthålla sin motivation.

    Slutsats: Stöd och motivation ger högre möjligheter för personer att främja sin hälsa genom att skapa sig nya goda hälsosamma levnadsvanor och därmed reducera riskerna för följdsjukdomar. Genom egenvårdshandlingar kan personen uppnå välbefinnande då det främjar egen hälsa och personens utveckling hos sig själv.

    Maktdynamiker, rationalitet och planeringsföreställningar2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Den här uppsatsen antar en kritisk ansats med ambitionen att synliggöra maktförhållanden som formar den offentliga planeringen. I uppsatsen konstrueras en kritisk-teoretisk modell som beskriver hur simultant interna/implicita och externa/explicita ’maktdynamiker’ kopplat till ’rationalitet’ opererar genom ’planeringsföreställningar’. Den kritisk-teoretiska modellen förenar två forskningsfält; ’planeringsföreställningar’ och ’rationalitet-makt-relationer’ i syfte att analysera hur ’maktdynamiker’ opererar inom offentlig planering.

    ’Maktdynamiker’ beskriver övergripande nätverk av makt som yttrar sig på olika skalnivåer genom att individer och grupper ansluter sig till dem. Maktdynamiker är överlappande, motstridiga, beständiga och föränderliga maktstrukturer. Subjektets agerande är involverat i maktdynamiker som både påverkar och påverkas av agerandet och producerar samhälleliga effekter. ’Rationalitet-makt-relationer’ exemplifieras bland annat av kunskapsanspråk, sanningsanspråk, legitimering av processer och politisk koncensus som stabiliserar maktrelationer. Rationalitet-makt-relationer kan både medvetet och omedvetet maskera prioriteringar och maktutövande som ’självklarheter’ vilket gör att de sällan är föremål för öppna konflikter. Trots det har rationalitet-makt-relationer stor betydelse inom demokratiska organisationer och planering. ’Planeringsföreställningar’ utgör planeringens idémässiga förutsättningar och analyseras som det sätt den offentliga planeringen föreställt möjligheten att styra stadsutvecklingen. Sådana föreställningar utgör planeringens möjligheter och begränsningar samtidigt som föreställningarna påverkas av försöken att planera. Planeringsföreställningar härleds till rationalitet utifrån en grundläggande uppfattning om att planering syftar till att styra och påverka samhällsutvecklingen med hjälp av förnuftet – vilket i sig är en rationalitet-makt-relation oavsett problemformulering och övrigt innehåll. Sammantaget beskriver uppsatsens kritisk-teoretiska modell planeringens och rationalitetens omedelbara relation varandra och till makt.

    Analysen involveras i de rationalitet-makt-relationer som formar den offentliga översiktsplaneringen där en exemplifierande fallstudie utgör uppsatsens empiriska kontext. Fallet är intressant dels eftersom lagen ger stora friheter i hur översiktsplanering används. Friheten kan innebära att planeringsföreställningar hos nyckelaktörer inom översiktsplaneringen får stort inflytande över översiktsplaneringens form och innehåll. Analysen visar inte bara hur planeringsföreställningar varierar mellan individer utifrån ambivalensen i och med det tillsynes omöjliga uppdraget att ordna samhället med förnuftet. Planeringsföreställningar kan också variera beroende på vilka övergripande maktdynamiker de relateras till. Analysen är en successivt framvuxen konstruktion av tre ’kritiska belysningar’ där planeringsföreställningar analyseras i förhållande till ’den egna organisationen’, ’marknaden’ respektive ’medborgare’ (samtliga i obestämd, dynamisk och multipel ’form’). I relation till medborgare, politik och andra förvaltningar framhålls planeringssubjektet som autonomt och översiktsplanen legitimeras som ett ’kunskapsanspråk’ eller ’sanningsanspråk’ om stadens utveckling. Rationaliteter i förhållande till dessa föreställningar lägger fokus på bostadsproduktionen och att processerna ska kunna fortgå. Andra förvaltningar ska följa översiktsplanen och medborgare ska få en förståelse för att staden växer. I förhållande till marknaden är föreställningar om möjligheten att styra stadsutvecklingen mer flexibla och anpassningsbenägna då marknaden ses som den ’sanning’ planeringen har att förhålla sig till. Marknadens ’realism’ ska implementeras också för att stärka översiktsplanens ställning. På det sättet beskrivs hur översiktsplaneringen upprätthåller och stabiliserar maktförhållanden utifrån rationalitet-makt-relationer till förmån för bostadsproduktionen.

    Varumärkespåverkan i sociala medier: Hur varumärkescommunities på Facebook påverkar konsumentrelationer och varumärken2014Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Som den största webbaserade portalen har Facebook blivit en viktig plattform för många företag. Ett enkelt sätt att kommunicera med sina kunder är genom att företaget administrerar sitt egna varumärkescommunity på Facebook. Studier har visat på möjligheter för företag att stärka relationer till konsumenter och även höja varumärkesvärde, men risker med b.la. negativ åsiktsspridning har ändå lett till debatter om varumärkescommunities verkliga påverkan för företag. Denna studie undersöker hur varumärkescommunities på Facebook i Sverige påverkar olika konsumentrelationer och vilken påverkan de har på svenska varumärken. Detta görs genom att analysera hur relationer mellan konsument, produkt, varumärke, företag och andra konsumenter påverkas av varumärkescommunities. Undersökningen kombineras med tidigare forskning om b.la. varumärken, varumärkestillit och varumärkeslojalitet och slutsatserna baseras på en enkätundersökning med 108 respondenter. Resultaten visar på att varumärkescommunities på Facebook i Sverige har positiv påverkan på relationer mellan konsument, produkt och andra konsumenter, och även positiv påverkan på svenska varumärken.

    Primary healthcare nurses' experiences of physical activity referrals: an interview study2015In: Primary Health Care Research and Development, ISSN 1463-4236, E-ISSN 1477-1128, Vol. 16, no 3, p. 270-280Article in journal (Refereed)
    Abstract [en]

    CONCLUSION: Our findings suggest that viewing the PAR as a complex intervention, with all that this entails, might be one approach to increasing the number of PARs being issued. Simpler systems, more time and the potential for testing the effectiveness of follow-ups could be possible ways of achieving this. AIM: The aim of this study is to illuminate primary health care (PHC) nurses' experiences of physical activity referrals (PARs). BACKGROUND: Despite extensive knowledge about the substantial health effects physical activities can produce, fewer and fewer people in our modern society regularly engage in physical activity. Within health care and, particularly, within the PHC arena, nurses meet people on a daily basis who need help to engage in a healthier lifestyle. The possibility of issuing written prescriptions for physical activities, often referred to as PARs, has been introduced as a tool to support such lifestyles. However, even though PHC nurses can prescribe physical activities, studies investigating their experience in this type of nursing intervention are rare. METHODS: For this study, 12 semi-structured interviews were conducted with PHC nurses, and the transcribed texts were analysed using a qualitative content analysis. FINDINGS: Two categories--PARs, an important nursing intervention, and PARs, the necessity of organisational support--reflected the nurses' experiences in using PARs.

    Yngre kvinnors upplevelser av cytostatikabehandling vid bröstcancer: En litteraturstudie av patografier2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: En av de vanligaste behandlingarna mot bröstcancer är cytostatika. Denna

    behandling upplevs som påfrestande då det ger biverkningar i form av illamående, trötthet,

    smärta och håravfall. Yngre kvinnor som ej genomgått menopaus och insjuknar i bröstcancer

    är i en annan period i livet jämfört med de i genomsnittsåldern (60+). Det är därför viktigt att

    sjuksköterskan arbetar personcentrerat för att kunna bemöta dessa kvinnor under deras

    behandling med cytostatika och hur det kan påverka deras dagliga liv. Personcentrerad

    omvårdnad utgår ifrån deras livssituation och bidrar förhoppningsvis till ett minskat lidande.

    Syfte: Syftet med studien var att belysa yngre kvinnors upplevelser av cytostatikabehandling

    vid bröstcancer.

    Metod: Kvalitativ litteraturstudie baserad på tre patografier. Resultatet har analyserat med

    inspiration av Graneheim och Lundmans sammanställning av kvalitativ innehållsanalys.

    Resultat: Analysförfarandet resulterade i tre kategorier: Kroppsliga förändringar,

    Emotionella reaktioner och Längtan till ett vanligt liv. Kroppsliga förändringar har

    underkategorin: Att förlora sitt hår. Resultatet indikerar på att cytostatikans effekter

    påverkade kvinnorna negativt. Håravfallet gav en förändrad självbild och framkallade en

    känslostorm där ångest och rädsla var mest framträdande. Trots cytostatikabehandlingens

    effekter kände kvinnorna hopp och en längtan att få återgå till sitt vanliga liv.

    Slutsats: Det var när cytostatikabehandlingen påbörjades som kvinnorna i studien upplevde

    att de blev sjuka. Cytostatikabehandlingen medförde en insikt av allvaret i situationen när

    effekten av cytostatikan främst gav kvinnorna kroppslig påverkan. En fördjupad förståelse för

    dessa kvinnors situation ger sjuksköterskan större möjlighet att skapa ett bättre möte och ge

    personcentrerad omvårdnad utifrån deras individuella förutsättningar. Vidare forskning krävs

    för att sjuksköterskan ska få en djupare förståelse för hur cytostatikabehandling kan påverka

    yngre kvinnors livssituation.

    Predicting burglars' risk exposure and level of pre-crime preparation using crime scene data2018In: Intelligent Data Analysis, ISSN 1088-467X, Vol. 22, no 1, p. 167-190, article id IDA 322-3210Article in journal (Refereed)
    Abstract [en]

    Objectives: The present study aims to extend current research on how offenders’ modus operandi (MO) can be used in crime linkage, by investigating the possibility to automatically estimate offenders’ risk exposure and level of pre-crime preparation for residential burglaries. Such estimations can assist law enforcement agencies when linking crimes into series and thus provide a more comprehensive understanding of offenders and targets, based on the combined knowledge and evidence collected from different crime scenes. Methods: Two criminal profilers manually rated offenders’ risk exposure and level of pre-crime preparation for 50 burglaries each. In an experiment we then analyzed to what extent 16 machine-learning algorithms could generalize both offenders’ risk exposure and preparation scores from the criminal profilers’ ratings onto 15,598 residential burglaries. All included burglaries contain structured and feature-rich crime descriptions which learning algorithms can use to generalize offenders’ risk and preparation scores from.Results: Two models created by Naïve Bayes-based algorithms showed best performance with an AUC of 0.79 and 0.77 for estimating offenders' risk and preparation scores respectively. These algorithms were significantly better than most, but not all, algorithms. Both scores showed promising distinctiveness between linked series, as well as consistency for crimes within series compared to randomly sampled crimes.Conclusions: Estimating offenders' risk exposure and pre-crime preparation  can complement traditional MO characteristics in the crime linkage process. The estimations are also indicative to function for cross-category crimes that otherwise lack comparable MO. Future work could focus on increasing the number of manually rated offenses as well as fine-tuning the Naïve Bayes algorithm to increase its estimation performance.

    Vuxna personers upplevelser av att leva med en behandlingsbar cancersjukdom: En litteraturstudie baserad på patografier2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Minst var tredje person i Sverige beräknas få en cancersjukdom någon gång under livet. En behandlingsbar cancersjukdom kan innebära ett flertal förändringar i personens liv. Förändringarna kan gälla till exempel tankar, känslor och kroppsliga förändringar. Många personer med en behandlingsbar cancersjukdom upplever brister när det kommer till stöd från vårdpersonal. För att kunna anpassa omvårdnaden kring vuxna personer med en behandlingsbar cancersjukdom behövs ökad kunskap och förståelse kring hur det är att leva med behandlingsbara cancersjukdomar.

    Syfte: Syftet med studien var att beskriva vuxna personers upplevelser av att leva med en behandlingsbar cancersjukdom.

    Metod: Studien genomfördes som en litteraturstudie baserad på patografier. Analysen gjordes med hjälp av Graneheim och Lundmans tolkning av en kvalitativ innehållsanalys.

    Resultat: Analysen ledde fram till fem kategorier och två underkategorier. Den första kategorin var en känsla av personlig förändring. Den andra kategorin var längtan tillbaka till det gamla livet. Nästa kategori var tankar om döden. Den fjärde kategorin var att känna styrka med underkategorierna vilja och kämpaglöd och nära och käras betydelse. Den sista kategorin var tankar om framtiden.

    Slutsats: En känsla av personlig förändring med avsnittet kring en förändrad syn på och känsla för kroppen, tankar om döden samt vilja och kämpaglöd var tre utmärkande upplevelser i resultatet. Genom en förståelse kring upplevelser hos vuxna personer med en behandlingsbar cancersjukdom kan vårdpersonal och nära och kära minska lidandet och öka välbefinnandet hos personerna. Något som framkom i föreliggande studie var att nära och kära hade en betydelsefull roll för personerna med en behandlingsbar cancersjukdom. Vidare forskning skulle därför vara intressant att göra kring anhörigas perspektiv av att leva i närheten av en person med en behandlingsbar cancersjukdom.

    Ett grönområdes framtid: - utifrån människans utbredning och naturens behov2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    I Stockholms län finns ett stort behov av att bygga bostäder, arbetsplatser och infrastruktur. Orsaken till utbyggnadsbehovet av bostäder är en befolkningsökning inom länet. Utbyggnaden sker både genom påbyggnad av befintliga huskroppar, förtätningar, återanvändning av sedan tidigare hårdgjorda ytor men också genom att använda marken i befintliga parker och natur.

    I mitt arbete har jag en forskningsfråga/hypotes om att det är möjligt att bygga inom ett grönområde utan att dess värde förloras.

    För att utreda hur ett grönområdes värden kan påverkas vid ny bebyggelse har jag valt att studera två olika områden, Kymlinge och Söderby, som ligger inom Järvakilen och göra en jämförelsestudie mellan dessa. Grönområdet, Järvakilen, är en av Stockholms grönkilar som bland annat fungerar som rekreationsområde.

    Planförslagen för Kymlinge och Söderby grundas på närbesläktade förutsättningar såsom närhet till rekreationsområde med natur, infrastruktur med vägbuller från ett stort flöde av trafik och kraftledningsgator. En skillnad däremot är avståndet till närliggande tätort. I båda fallen tas delvis jungfrulig mark i anspråk. Lite speciellt för Kymlinge är att här finns en tunnelbanestation uppförd som inte har blivit färdigställd och att ett kommunalt naturreservat har inrättats. I jämförelsen har likheter och skillnader i planeringen tagits fram utifrån inventering, analys och planförslag.

    The regional impact of low-cost carriers: Case study of Katowice and Skavsta airports2009Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    In our thesis we have presented the airports’ activity in the scope of impact of the Low Cost Carriers based on two cases: Katowice and Skavsta Airports. By analyzing the indicators for airports’ growth we described how the advantage of LCCs have affected in perceiving the airports, their regions and the LCCs’ services itself. We have found out that there’s a connection between the economic condition of the region and the types of services which the LCCs have in offer. Since both airports are facing similiar scale of the expansion, different drivers found in the regions’ features were stimulating the air traffic and shaping a dominant profile of the passenger. Following the patterns in respect to tourism we have concluded that the limitations which occur around low-cost services possibly shape the behaviour of travel planning. Whereas the activity of LCCs’ services are generally recognized as profitable to the region, we argue that in some cases the neighbourhood hampers the development in this sector.

    Antecedents of creativity and innovativeness in the Swedish manufacturing pharmaceutical industry2014Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    The ability to create new products and services is a competitive advantage and in many cases a requirement for long term success of a company. In the manufacturing pharmaceutical industry, the freedom to think and act creatively is depressed by the demand for external and internal compliance. As such, it is important to understand the underlying factors of creativity and innovativeness in order to promote them. Several studies have been performed on the subject to increase creativity. A theme that is recurrent in several creativity increasing studies it that leadership and the leadership style of the management is important for creativity. The purpose of this thesis was to investigate if the leadership style transformational leadership can be associated with a higher level of creativity and innovativeness in the Swedish pharmaceutical industry. Given that the effect of transformational leadership on creativity is likely to be derived from creativity enhancing variables that have been enhanced in the follower’s a literature framework is built to find, and in turn empirically test, if this effect of transformational leadership (if any) is mediated by other variables. The thesis contains a literature review of current leadership and creativity theories as well as literature review of intrinsic motivation and psychological empowering. From the theoretical framework 10 hypothesis´s about performance, transformational leadership, creativity, innovativeness, intrinsic motivation and psychological empowering were stated. The hypothesis’s was tested trough an empirical study. Data was gathered by a questionnaire that was sent out to 22 manufacturing pharmaceutical companies in Sweden. The results of the study support the idea that transformational leadership increases creativity and innovativeness in the investigated market. However, no correlation was found between transformational leadership and intrinsic motivation or psychological empowering. While not the central question of this thesis the study also supports that a higher level of creativity and innovativeness is correlated with a higher performance.

    Nonviolent Communication: a Communication Tool to support the Adaptive Capacity of Organisations?2017Independent thesis Basic level (degree of Bachelor), 20 HE creditsStudent thesis
    Abstract [en]

    Adaptive capacity is essential for organisations to be able to adapt to the sustainability challenge, and change its course. Nonviolent Communication (NVC) is an interpersonal communication tool that enables a user to move from a language of judgements to a language of needs by using 4 steps: observation, feelings, needs, and request. As communication is essential to the adaptive capacity of a social system, this thesis explores the question: How does Nonviolent Communication support the adaptive capacity of organisations? Through a mixed methods approach (semi-structured interviews and surveys with NVC trainers, organisational representatives and employees), the effects of NVC on communication in 3 sample organisations in the Netherlands (a school, NGO and research institute), is explored. Quantitative survey results show that NVC has a positive to very positive effect on common organisational communication dynamics. Qualitative data supports this finding and shows that NVC brings positive effects of increased understanding, listening, and progress in work related issues through an increased awareness of one’s own and other’s needs and feelings. When linking these results to adaptive capacity of organisations, it is concluded that NVC directly supports the adaptive capacity elements of trust, diversity and learning, and indirectly supports common meaning and self-organisation.

    Bevara eller utveckla?: En fallstudie i hur kommuner hanterar kulturmiljöer i en tid av förtätning2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    En studie av Riksantikvarieämbetet synliggör att två av tre svenska kommuner saknar förutsättningar för att ta hänsyn till kulturmiljövärden i den fysiska planeringen. Samtidigt ställs krav på kommunerna att öka bostadsbyggandet i ljuset av den rådande bostadsbristen. Således synliggörs en problematik där förtätning som utgör en samtida planeringsnorm behöver kunna genomföras utan att kulturmiljöer påverkas negativt. Omvandling av äldre hamn- och industriområden har präglat stadsutvecklingen i Europa sedan 1980-talet och i dessa omvandlingar finns ofta en strävan att bevara spår från de gamla verksamheterna. I den ovan beskrivna problematiken tar uppsatsen sitt avstamp.

     

    Uppsatsen genomförs som en fallstudie om hur expansiva kommuner hanterar kravet att tillgodose kulturmiljöer inom ramen för hamn- och industriomvandlingar. Genom en kvalitativ textanalys studeras empirin som utgörs av kommunala plandokument såsom översiktsplaner, detaljplaner, planprogram samt kommunala kulturmiljöprogram. Studieobjekten är Malmö, Nacka och Göteborgs kommun, där den sistnämnda används i syfte att belysa en eventuell skillnad över tid i hantering av kulturmiljöer. För att besvara frågeställningarna tolkas sedan empirin utifrån teorierna “kreativa klassen” och “platsmarknadsföring” samt ställs mot forskning inom ämnesfältet.

     

    Ur empirin har det kunnat skönjas att kommunerna uppvisar liknande tillvägagångssätt i hur kulturmiljöer ska tillgodoses, där en integrering av kulturmiljöerna i den nya bebyggelsen förefaller vara det vedertagna angreppssättet i hanteringen av att tillgodose kulturmiljöer. Denna strategi går även i linje med vad som föreskrivs av forskning. Genom att sätta detta i ljuset av de valda teorierna, kan tolkningar göras att ekonomiska motiv är en stark drivkraft i bevarandet av kulturmiljöerna. I uppsatsens diskussionsdel förs en diskussion kring vad som framkommit på på varje frågeställning, genom att väva in exempel från de studerade kommunerna.

    Validation of the verbal and social interaction questionnaire for nursing students: The focus of nursing students in their relationship with patients2018In: Journal of Nursing Education and Practice, ISSN 1925-4040, E-ISSN 1925-4059, Vol. 8, no 4, p. 81-88Article in journal (Refereed)
    Abstract [en]

    The Verbal and Social Interaction Nursing Students questionnaire (VSI-NS) has been created to measure the development ofverbal, social and interactional skills of nursing students with patients, from their perspective in nursing care. The aim of thepresent study was to determine the construct validity and internal consistency reliability of the questionnaire. The study had amethodological and developmental design and was carried out in four steps: adjustment of the items, face validity, data collectionand data analysis. The number of items was reduced from 48 to 31. The factor analysis of the final 31 items resulted in four quitedistinct factors: “Inviting to talk about feelings and thoughts”, “Building a caring relationship”, “Encouraging social and practicalaspects in daily life” and “Caring towards health and wellbeing”. The results showed satisfactory psychometric properties interms of content validity, construct validity and the internal consistency reliability of the questionnaire. It could be concluded thatthe original conceptual model could serve as a theoretical foundation to explain and understand nurses’ caring interactions withtheir patients

    Bostadsbrist trots ökat bostadsbyggande, om ansvar och behov: En fallstudie2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Det råder bostadsbrist i Sverige, trots att det återigen byggs bostäder i högt tempo. Flera orsaker kan förklara den stora bostadsbristen. Sveriges befolkning har ökat med 25% den senaste årtionden, delvis till följd av ökad invandring. Samtidigt pågår en fortsatt urbanisering som ökar trycket på bostäder i storstadsregionerna. Miljonprogrammet ledde till moderna bostäder under 1960-1970-talet, men i början av 1990-talet var bostadsmarknaden mättad. När befolkningen idag återigen ökar saknas det bostäder. I Sverige är det en generell bostadspolitik som varit och är dominerande, vilken bygger på socialistiska grunder där alla skulle ha rätt till bostäder med hög standard. Den bostadspolitiska modellen har sedan 1980-talet utmanats och influerats av nyliberala tankegångar. Den generella bostadspolitiken och nyliberalism står till viss del i motsats till varandra och det är därför av intresse att undersöka hur kommuner och bostadsbolag förhåller sig till det bostadsförsörjningsansvar som lagstiftningen beslutat om. Det kan ge en ökad förståelse för hur det kommunala bostadsförsörjningsansvaret tillämpas.

     

    Syftet med studien är att undersöka Stockholms stads kommunala bostadsförsörjningsansvar i förhållande till bostadsmarknadens behov och den rådande bostadsbristen. Syftet är vidare att förstå bostadsbristens problematik ur den historiska kontexten och samtidens nyliberala influenser. Det har gjorts genom en kvalitativ fallstudie där Stockholms stads bostadsförsörjningsprogram tillsammans med deras kommunala bostadsföretag har studerats för att se hur de omsätter sitt ansvar i praktiken för att möta behovet på bostäder.

     

    Studien visar på att det finns ett visst glapp mellan lagstiftningens intention och Stockholms stads tillämpning. Det delvis på grund av den svängning som skett i svensk bostadspolitik med nyliberala influenser. Tillika har inte behovet av bostäder tillgodosetts på ett tillfredställande vis, något som pekar på att svensk bostadspolitik behöver förändras. Ur resultatet framgår att Stockholms stad i sitt bostadsförsörjningsprogram och deras kommunala bostadsbolag lägger stort ansvar på privata aktörer för att tillgodose bostadsbehovet. Studien visar på att behovet på bostäder inte tillgodosetts och då i synnerhet inte segmentet i bostadsstocken där studien visar att behovet är som störst.

    Hälsosam stadsplanering: en fallstudie av Stockholm, Göteborg och Malmö2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Fysisk planering är ett område som har möjlighet att påverka många olika delar i samhället. Det innebär således att arbetet med en god fysisk planering är viktigt för att samhället ska fungera på ett bra sätt. Denna studie undersöker närmre hur fysisk planering används för att främja människors hälsa och välbefinnande i de tre kommunerna Stockholm, Göteborg och Malmö. Hälsa och välbefinnande borde vara en självklarhet att sträva efter i stadsplaneringen de menar i alla fall forskare som arbetar för WHO och som denna studie tar sin grund i. De lyfter en oro om att stadsplaneringen börjar glömma bort hur viktiga dessa aspekter är runt om i Europa. Stämmer detta även i en svensk kontext? Eller har vi i Sverige ett sätt att planera som tillgodoser människors hälsa och välbefinnande? Det är frågor som studien diskutera och försöka hitta svar på. Det har under studiens gång framkommit att Hälsosam stadsplanering så som Barton och Tsourou (2000) beskriver den har mycket att göra med att skapa förutsättningar för stadens invånare att förändra sin livsstil. En av de huvudsakliga delarna har visat sig vara att öka möjligheten för människor att röra sig mer till vardags genom att planera för städer där gång och cykel är naturliga transportmedel. Det räcker inte bara att förbättra gång och cykelvägar. Det handlar således om att stadens struktur bör vara anpassad efter närhet och med god tillgång till den vardagliga servicen så att behovet av att transportera sig med bil försvinner. Det har visat sig att denna strategi är något som alla tre kommunerna i undersökningen har anammat och redan där har det kunnat konstateras att kommunerna är en god bit på vägen att tillämpa en hälsosam stadsplanering. Men begreppet rör så mycket mer till exempel boendekvalité, social sammanhållning och tillgänglighet.

    Så länge jag minns vill jag berätta: En litteraturstudie om Alzheimers sjukdom baserad på patografier.2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Alzheimers sjukdom är den vanligaste demenssjukdomen i Sverige och varje år insjuknar cirka 15 000 personer. Det finns inget botemedel utan hälso- och sjukvårdens insatser bör riktas mot att underlätta tillvaron för personen som insjuknat. För att sjuksköterskan på bästa sätt ska kunna bemöta den unika upplevelsen en person har av den egna sjukdomsupplevelsen bör sjuksköterskan tillämpa personcentrerad vård.

    Syfte: Syftet med studien var att beskriva personers egna upplevelser av att leva med Alzheimers sjukdom.

    Metod: En litteraturstudie med kvalitativ ansats baserad på patografier. Innehållsanalys utförd utifrån Graneheim och Lundmans pedagogiska modell för textanalys med en manifest ansats.

    Resultat: I studien framkom tre kategorier. Under kategorin Ett förändrat jag beskriver personerna med sjukdomen hur den förändrar deras person och begränsar deras kapacitet. Under kategorin Ett förändrat socialt liv upplever personerna förändringar i de nära relationerna, ett ökat behov av stöd samt en upplevd förändring ibland andra när sjukdomen är uttalad. Den sista kategorin Sjukdomen som ett hot mot den egna existensen visar att personer med sjukdomen upplever avsaknad av kontroll i sjukdomens förödande process och att framtiden är oviss. Samtidigt förser dock sjukdomen personerna med en möjlighet att ta till vara och uppskatta varje dag.

    Slutsats: Studiens resultat visar att personer med Alzheimers sjukdom upplever att livet förändras i grunden. Den egna personen förändras, det sociala livet påverkas och att sjukdomen verkar som ett hot mot den egna existensen. Genom att sjuksköterskan känner till hur personer med Alzheimers sjukdom kan uppleva sin tillvaro med sjukdomen kan sjuksköterskan stärka vårdrelationen och sätta personen i centrum för vården.

    Multisensory Expert-Based Support System for the Firefighter’s Training Performance Evaluation2018Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The primary purpose of this thesis work is to design and implement a system supporting the fire-fighter’straining evaluation. The solution presented in this report comprises a real-time locating system andInertial Measurement Unit that collect the training data and an application built with the Unity3D gameengine used for processing.

    Before the presented application can process any data, a training facility must be recreated, and atrainer or an expert must define training guidelines, such as zones that a trainee must visit, objectshe/she has to see, and the required execution time. After this preparation and completed trainingsession, collected data is processed and the visualization together with evaluation process begins. Theprogram visualizes trainee’s position and his/her field of view and evaluates his performance. For thelatter, it uses the Unity3D collision detection feature. After the evaluation, the trainer can see detailedresults with recorded time stamps, and using them, he/she can fast forward to specific, important points,reducing the time to analyze trainee’s performance throughout the whole training.

    Tests which the authors conducted confirm that the built system meets requirements and is useful forevaluation of the trainee’s performance.

    Optimisation Of Ionospheric Scintillation Model Used In Radio Occultation2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis is executed in cooperation with RUAG Space AB, which specializes in highly reliable on-board satellite equipment. The thesis focuses on the effect, which disturbs the amplitude and phase of a Global Positioning System (GPS) signal, called scintillation effect. It has a substantial impact on a GPS signal, during Radio Occultation (RO). RO is a method of analysis of a refracted signal which passes through the atmosphere. RO can be used for measuring climate change and for weather forecasting. By retrieving the bending angle of a GPS signal, three basic parameters of the Earth’s atmosphere can be obtained at different heights: temperature, pressure and humidity. As the scintillation effect causes prominent errors in the bending angle calculations, it is crucial to provide possibly the most precise mathematical model, which allows to conceive proper ionospheric corrections. In this thesis, the model using Rytov approach is implemented and optimised with different optimisation functions. It is shown that the scintillation model can be optimized, which may contribute to a more accurate retrieval of the atmospheric profiles.
