    Importance of Urban Squares as Public Space in Social Life: A New Design of Fisktorget in Karlskrona City2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Nowadays, the impact of technological growth‏ ‏on people’s life and our society is remarkable, ‎inevitable and also worrying. The excessive influence of technology in ‎individuals’ lives has caused our community to change towards more privatisation and ‎secluded life. At this point, the role of urban public spaces in social life has become more ‎prominent and significant. Issues of social life in public spaces and the relations with creating a ‎vibrant and dynamic city has not been given too much attention in urban planning and design. ‎This thesis raises the question of considering public spaces and how urban public spaces ‎‎(especially squares) can encourage/persuade citizens ‎to increase social interaction‎. Initially, it describes a clear definition of public spaces and urban squares. Thereafter, the study addresses ‎effectual factors from the human perspective which can help to achieve the successful design of an ‎urban public square. The aim of the work is to comprehend how it might be possible to improve ‎social life and behaviour in public spaces (squares) and consequently to attain a framework in ‎order to design. Ultimately, a design is proposed for Fisktorget (Fish Square), which is one of most important public places in the Karlskrona city in Sweden. The proposed design is based on studies and analyses that have been done throughout this thesis.

    The effects of environmental uncertainty conditions on organisational innovativeness and performance of SMEs.2014Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Innovativeness is considered to be an important factor for firm’s survival and their ability to compete in today’s market. Therefore, researchers have become more interested in studying innovativeness and its drivers. Studies have also showed that there’s a positive relationship between environmental uncertainty and innovativeness. Organisations are responsive to turbulent environments through innovativeness in order to stay competitive and improve performance. The purpose of this thesis is to rank critical environmental factor’s effect on organisational innovativeness of small and medium enterprises in Sweden, through investigating the impact of market/demand turbulence and technological turbulence on innovativeness. Additionally, we want to examine the relationship between innovativeness and business performance, as well as the indirect relationship between environmental uncertainty and performance. Based on previous literature, we have developed hypotheses and proposed a research model to study the formulated problems. Data for the study were collected from 50 SMEs in Sweden, through a survey with well-known scales and were analysed using regression analysis. The results of the study, reveal that environmental uncertainty has a positive effect on the innovativeness of SMEs. In addition, technological turbulence showed to have a positive significant effect on an SME’s innovativeness; however, contrary to general belief, market/demand turbulence did not have any prominent effect. Our findings also proved that innovativeness have a strong positive impact on business performance, and that only technological turbulence have an indirect influence on performance through innovativeness. This study aimed to contribute to the management a better understanding, of which conditions of environmental turbulences SMEs should adapt to, in order to increase their level of innovativeness. Keywords: environmental uncertainty, organizational innovativeness, performance, market/demand turbulence, technological turbulence, SMEs.

    Små oberoende företags attityd till kontanter och kort som betalmedel2014Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Syfte: Syftet med denna uppsats är att undersöka vilken attityd mindre oberoende företag har till kontanter och betalkort som betalmedel i allmänhet och vid låga köpesummor i synnerhet. I undersökningen kommer vi att studera vid vilken summa som handlarna upplever det som acceptabelt att kunder betalar med betalkort. Metod: Studien har genomförts med hjälp utav en kvantitativ metodansats, då vi ville få en bred förståelse för småföretagarnas syn utav olika betalmedel i allmänhet samt vid betalningar under 100 kronor i synnerhet. För att ta del utav förståelsen kring vår studie utgick vi ifrån det positivistiska synsättet, då vi efterstävar kunskap kring händelser som kan mätas. Vi genomförde enkätundersökningar med ett hundratal företagsägare ur urvalsgruppen för att kunna ta del utav den objektiva verkligheten och för att sedan påvisa denna med hjälp utav den numeriska informationen vi samlat in. Slutsats: Studiens resultat visade att urvalsgruppens inställning till olika typer utav betalmedel vid lägre köpesummor huvudsakligen var att kontanter var att föredra. En slutsats som går dra utifrån detta resultat är att kortbetalningssystemet grundar sig i en felaktig prissättning vid låga köpesummor där bankerna tar ut en procentuellt hög avgift vid varje korttransaktion. För att öka kortbetalningarna vid låga summor krävs det att prisstrukturen ses över något som skulle kunna göras genom att ett subventionssystem upprättas alternativt att banken sänker transaktionskostnaden. För framtida betalmedel visar studiens resultat att det är viktigt att ta i beaktande att det blir ett enhetligt system med en balanserad prissättning.

    Philippe Aghion: recipient of the 2016 Global Award for Entrepreneurship Research2017In: Small Business Economics, ISSN 0921-898X, E-ISSN 1573-0913, Vol. 48, no 1, 1-8 p.Article in journal (Refereed)
    Abstract [en]

    Professor Philippe Aghion is the 2016 recipient of the Global Award for Entrepreneurship Research, consisting of 100,000 Euros and a statuette designed by the internationally renowned Swedish sculptor Carl Milles. He is one of the most influential researchers worldwide in economics in the last couple of decades. His research has advanced our understanding of the relationship between firm-level innovation, entry and exit on the one hand, and productivity and growth on the other. Aghion has thus accomplished to bridge theoretical macroeconomic growth models with a more complete and consistent microeconomic setting. He is one of the founding fathers of the pioneering and original contribution referred to as Schumpeterian growth theory. Philippe Aghion has not only contributed with more sophisticated theoretical models, but also provided empirical evidence regarding the importance of entrepreneurial endeavours for societal prosperity, thereby initiating a more nuanced policy discussion concerning the interdependencies between entrepreneurship, competition, wealth and growth.

    The effect of different mouth rinse products on intra-oral halitosis2016In: International Journal of Dental Hygiene, ISSN 1601-5029, E-ISSN 1601-5037, Vol. 14, no 2, 117-123 p.Article in journal (Refereed)
    Abstract [en]

    Aim: To evaluate the effect of different mouth rinses 12 h after rinsing on genuine intra-oral halitosis. Materials and Methods: Twenty-four adults with halitosis were included in a double-blind, crossover, randomized clinical trial. Halitosis was evaluated 12 h after rinsing with placebo and five mouth rinse products containing zinc acetate and chlorhexidine diacetate; zinc lactate, chlorhexidine and cetylpyridinium chloride; zinc acetate and chlorhexidine diacetate with reduced amounts of mint and menthol; zinc chloride and essential oil; and chlorine dioxide using the organoleptic method and a gas chromatograph. Test periods were separated by 1 week. Results: Hydrogen sulphide (H2S), methyl mercaptan (MM) and the organoleptic scores (OLS) were significantly reduced 12 h following rinsing with all substances compared to placebo (P < 0.05). H2S was more effectively reduced after rinsing with zinc acetate and chlorhexidine diacetate and zinc acetate and chlorhexidine diacetate with reduced amounts of mint and menthol compared to rinsing with zinc chloride and essential oil (P < 0.05), and significantly lower values of MM were obtained after rinsing with zinc acetate and chlorhexidine diacetate compared to zinc lactate, chlorhexidine and cetylpyridinium chloride (P < 0.05). The percentage effectively treated individuals (H2S (<112 ppb), MM (<26 ppb) and OLS score <2) varied from 58% percentage (zinc acetate and chlorhexidine diacetate) to 26% (zinc chloride and essential oil). Conclusion: All treatments resulted in reduction in halitosis 12 h after rinsing compared to placebo. H2S and MM were most effectively reduced by zinc acetate and chlorhexidine diacetate.

    The effect of periodontal therapy on intra-oral halitosis: a case series2016In: Journal of Clinical Periodontology, ISSN 0303-6979, E-ISSN 1600-051X, Vol. 43, no 5, 445-452 p.Article in journal (Refereed)
    Abstract [en]

    Aim: The aim of this study was to evaluate the effects of non-surgical periodontal therapy on intra-oral halitosis 3months after therapy. Material and methods: Sixty-eight adults with intra-oral halitosis were included in a case series. Intra-oral halitosis was evaluated at baseline, and at 3months after treatment using the organoleptic scores (OLS), Halimeter (R), and a gas chromatograph. Results: Significant reductions for OLS (p<0.01), total sum of volatile sulphur compounds (T-VSC) (p<0.01) and methyl mercaptan (MM) (p<0.05) values were found after treatment. Hydrogen sulphide (H2S) levels were not significantly reduced. The numbers of probing pockets 4mm, 5mm and 6mm were significantly reduced as a result of therapy (p<0.001). Bleeding on probing (BOP) and plaque indices were also significantly reduced (p<0.001). For the 34 individuals with successful periodontal treatment (BOP<20% and a 50% reduction of total pocket depth) reductions in OLS (p<0.01) and T-VSC scores (p<0.01) were found. Eleven individuals were considered effectively treated for intra-oral halitosis presenting with a T-VSC value <160ppb, a H2S value <112ppb and a MM value <26ppb. Conclusion: Non-surgical periodontal therapy resulted in reduction of OLS, MM and T-VSC values 3months after therapy. Few individuals were considered as effectively treated for intra-oral halitosis.

    Platser för avskildhet: Att få vara ifred i offentliga rum2014Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Detta arbete undersöker utifrån ett teoretiskt perspektiv offentliga rum och vilka funktioner dessa platser anses fylla. Det övergripande syftet har varit att studera hur aspekterna mötesplats och avskildhet behandlas i samband med begreppet offentliga rum. Detta genom att först identifiera flertalet relevanta nyckelord utifrån uppsatsens teoretiska utgångspunkter. Nyckelorden har sedan applicerats på ett empiriskt material, i detta fall Västerås Översiktsplan, för att undersöka vad som framställs som betydelsefullt i och med användningen av offentliga rum. Det som framkommit genom innehållsanalysen är att offentliga rum anses fylla framförallt en viktig funktion i staden. Funktionen som mötesplats. Där människor med olika bakgrund både spontant och planerat ska kunna mötas och umgås. Möten som inte visar sig problematiseras utan enbart ses som något positivt. Undersökningen visar vidare att begreppet avskildhet inte alls lyfts. Liknande begrepp så som rekreation, avkoppling, vila, lugn och ro framhålls dock som viktiga aktiviteter som offentliga rum ska skapa förutsättningar för. Emellertid påvisas att dessa aktiviteter kan komma att hamna i konflikt med andra funktioner, så som mötesplatser, skjutbanor och motorsportanläggningar. Det framkommer slutligen att funktionen av offentliga rum anses bygga på föreställningen om att dessa rum ska utgå från en social grund och att de ska utsätta individer för varandra. Avskildhet och att få vara ifred visar sig istället vara en aktivitet som får utövas i det egna hemmet.

    Arbete med och uppföljning av CSR: En jämförande studie av socialt hållbart företagande inom tre statliga företag2014Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Uppsatsens syfte har varit att ge indikationer på förekommande CSR-verktyg och arbete relaterat till socialt hållbart företagande samt dess effekter inom svenska statliga företag. Genom att relatera de statliga företagens hållbarhetsarbete med dess effekter kan uppsatsen bringa information till detta, hittills, outforskade område samt visa på vilka utfall detta socialt hållbara arbete kan medföra. Uppsatsen använder som ansats och metod jämförande dokumentstudier av tre statliga företag – Apoteket, Systembolaget och Bilprovningen – valda utifrån ett idealistiskt urval till följd av deras framträdande roll inom hållbarhetsarbete bland statliga företag. Insamling av material genomfördes med hjälp av företagens hållbarhetsredovisningar samt andra tillgängliga informationskanaler. Undersökningen visar på både likheter, skillnader och mönster mellan studiens tre statliga företag. CSR-inriktade verktyg och processer existerar inom företagens uttalade strategier och planer, dock finns ett behov att förbättra processer kring uppföljning för att försäkra sig att arbetet drivs igenom enligt planerna samt att lärdomar kan dras från de utfall arbetet medför.

    Performance Analysis of a MIMO Cognitive Cooperative Radio Network with Multiple AF Relays2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    With the rapid growth of wireless communications, the demand for the various multimedia services is increasing day by day leading to a deficit in the frequency spectrum resources. To overcome this problem, the concept of cognitive radio technology has been proposed which allows the unlicensed secondary user (SU) to access the licensed spectrum of the primary user (PU), thus improving the spectrum utilization. Cooperative communications is another emerging technology which is capable of overcoming many limitations in wireless systems by increasing reliability and coverage. The transmit and receive diversity techniques such as orthogonal space–time block codes (OSTBCs) and selection combining (SC) in multiple-input multiple-output (MIMO) cognitive amplify and forward relay networks help to reduce the effects of fading, increase reliability and extend radio coverage.

     

    In this thesis, we consider a MIMO cognitive cooperative radio network (CCRN) with multiple relays. The protocol used at the relays is an amplify and forward protocol. At the receiver, the SC technique is applied to combine the signals. Analytical expressions for the probability density function (PDF) and cumulative distribution function (CDF) of the signal-to-noise ratio (SNR) are derived. On this basis, the performance in terms of outage probability is obtained. Mathematica has been used to generate numerical results from the analytical expressions. The system model is simulated in MATLAB to verify the numerical results. The performance analysis of the system model is hence done in terms of outage probability.

    Automatic Image Based Positioning System2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Position of the vehicle is essential to navigate the vehicle along a desired path without any human interference. Global Positioning System (GPS) loses significant power due to signal attenuation caused by construction buildings. A good positioning system should have both good positioning accuracy and reliability. The purpose of this thesis is to implement a new positioning system using camera and examine the accuracy of the estimated vehicle position on a real-time scenario.

    The major focus of the thesis is to develop two algorithms for estimation of the position of the vehicle using a static camera and to evaluate the performance of the proposed algorithms.

    The proposed positioning system is based on two different processes. First process uses center of mass to estimate the position, while the second one utilizes gradient information to estimate the position of the vehicle.

    Two versions of the positioning systems are implemented. One version uses center of mass concept and background subtraction to estimate the position of the vehicle and the other version calculates gradients to estimate the position of the vehicle. Both algorithms are sensitive to point of view of the image i.e height of the camera. On comparing both algorithms, gradient based algorithm is less sensitive to the camera view.

    Finally, the performance is greater dependent on the height of the camera position for center of mass positioning system, as compared to the gradient positioning system but the accuracy of the systems can be improved by increasing the height of the camera. In terms of the speed of processing, the gradient positioning system is faster than the center of mass positioning system. The first algorithm, based on center of mass has 89.75\% accuracy with a standard deviation of 3 pixels and the second algorithm has an accuracy of 92.26\%. Accuracy of the system is estimated from the number of false detected positions.

    Abstract [en]

    The purpose of this study was to identify ways by which entrepreneurial mobile banking growth could be accelerated in developing countries. An exploratory research method was adopted to identify the facilitators and obstacles to entrepreneurial mobile banking. The finding reveals some facilitators which include government policies and efforts of donor agencies, stiffer competition among banks, need for efficiency and lower cost, telecoms focus on customers retention. While some obstacles include conservative and vague regulation, security issues, underdeveloped infrastructures, lack of interoperability and lack of basic need for financial services. The main contribution of this study is the concise identification of the facilitators and obstacles to entrepreneurial mobile banking especially in developing countries. Suggestion for further study was made. The findings could be useful to policy-makers, donor agencies and other development partners in designing and directing their policies intervention

    Designing customer rewards programs for repeated purchase using optimization methods2015Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    A Customer Rewards Program (CRP) or a loyalty program is characterized by customers being rewarded for repeated purchases. The goal of these programs is to increase sales and profit through offering purchase incentives in the form of delayed rewards, as a result influencing customer behavior and in the end increasing company profit. It is an open debate in the literature if such reward programs are truly profitable for the company running it. This thesis therefore proposes a new approach to designing a CRP based on optimization methods with a focus on maximizing the expected profitability of the program. The key finding of the thesis is that such an approach can be applied to CRPs in order to increase the profitability of the companies running such programs. The approach offers promising results towards applicability to specific business segments and as a result towards maximizing the expected profits resulting from customer rewards programs. Since a largescale CRP may require significant developments on existing infrastructure and can pose high costs through the rewards redeemed during the program, the perspective of being able to maximize profits through fine-tuning the program parameters could be of great help. It can even be crucial to a company considering large investments on necessary developments or aiming to increase the returns on an existing CRP infrastructure. As part of the thesis we have analyzed the – at the time of writing – running CRP programs of several major companies present on the Hungarian market based on publicly available data in order to evaluate the applicability of the proposed optimization approach to real-world CRP designs. The analysis done on these real-world CRP designs indicates that the proposed optimization approach is applicable to a class of CRP designs witnessed to be popular among companies operating in various business segments. We have also investigated Hungary’s largest pharmacy-chain to gain insight into real-world CRP design considerations. Based on guided interviews conducted with the head of marketing at the aforementioned pharmacy-chain we conclude that the relevant information needed for our proposed optimization approach can be available to a company from business data (e.g. through billing and accounting information) readily available in an integrated IT infrastructure. We also conclude that the proposed theoretical results on CRP design are based on valid mathematical assumptions and correlate to accounting considerations related to the introduction of a CRP program.

    Enabling strategic change through business and IT alignment: Challenges for an organization’s management and leadership2014Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    The main objective for this thesis is to identify a set of challenges imposed on an organization undergoing strategic change impacting their IT Landscape. Organizations most embark on strategic change initiatives in order to remain competitive and create business value. It is important to understand these challenges imposed during the change process in order to be prepared and able to minimize the negative impact they may have if not handle properly. For this purpose within the scope of this thesis the aim is to identify challenge areas and the specific challenges they may impose. These identified challenges can be used as a baseline for organizations in order to understand which areas to address in order to minimize negative impact during a strategic change related to their IT Landscape. A case study methodology was used in this thesis and relevant research through literature review in identified topics was conducted. Communication, leadership, business value and strategy realization, knowledge management and change management are examined through the theoretical framework and identified as areas in need of attention during a strategic change initiative. Also within the theoretical framework this thesis identifies Enterprise Architecture as an enabler for succeeding with the change initiative related to the IT Landscape. The qualitative empirical data for this thesis was collected through the interview of ten professionals within four different organizations. Based on the above approach, within the scope for this thesis, a set of challenge areas and specific challenges were identified and the conclusion was that these areas are important to address during a strategic change initiative impacting IT Landscape within an organization in order to ensure a successful outcome.

    Purpose: Purpose of this paper is to analyze the circumstances under which social marketing affect the consumer's priority of functional and symbolic values with regards to the consumption of beef.

     

    Method: Written survey followed by interview session with focus on the three different segments of regular consumers of beef, flexitarians and vegetarians. These segments include both consumers and non- consumers of beef. All respondents who activly chose to restrict or refrain beef consumption has to base their decision on reasons which are other than religious.

     

    Results: This paper found possible situations where social marketing influenced the consumer behaviour with regard to beef consumption. This conclusion is based on the fact that all segments included in this paper mainly based their consumer behaviour on social information sources. The result also showed a tendency for the respondents in the segment of flexitarians to both influence and to be influenced by each other's consumer behavior.

     

    Keywords: Social Marketing, Consumption of Beef, Consumer behaviour

    How can the construction industry in Ghana become sustainable?2014Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    The Sub-Saharan African country of Ghana is growing at a rapid pace. The construction industry is striving to keep up with the increasing demand for housing and commercial and industrial space while simultaneously protecting the physical environment and social well-being of the country – a challenge becoming known in the industry as ‘sustainable construction.’ This paper proposes a strategic approach to manage these twin challenges, consisting of two parts: a building rating system and a participatory method called multi-stakeholder dialogue. The combination rating system and MSD process was presented to the industry to determine its potential effectiveness in assisting the industry to move towards sustainability. The industry’s response indicates that the proposal could be of value to the industry, with certain noted limitations. This paper describes the rating system-MSD proposal, the industry’s response, and implications for the construction industry in Ghana moving forward

    Abstract [en]

    Governments in both developing and developed countries provide services to its citizen however some provide better services than the others. Public services generally include facilities of health, education, electricity and water supply, social welfare, transportation, communication and other services. Countries face many challenges while providing these services to citizens and many developing countries have failed to provide the public services efficiently and are facing issues while providing service delivery to its citizens. One of the issues is corruption. The developing countries need to adopt e-governance and Information and Communication Technology (ICT) to overcome these issues. E-governance is a process of improving through Information Technology (IT), the way government works, shares information, interacts with clients (citizen, Business, Government) and provides services to clients. Our thesis will investigate whether ICT can combat corruption and improve Public Service Delivery (PSD) in developing countries. Findings of our study will help developing countries in combating corruption and improving public services. We have reviewed the literature related to public service delivery, corruption and its adverse effects, use of ICT and e-governance to combat corruption. We have adopted a case study approach to see what sorts of ICT initiatives are being taken by the government of Punjab to reduce corruption and improve the public services. In this regard we have explored the e-governance projects of PITB (Information Technology department of the Government of Punjab) including one of a recent project of PITB namely Citizen Feedback Model (CFM) which has got international attention worldwide for combating corruption and improving public services delivery. We have performed quantitative analysis on six months data set of CFM which was comprised of over one hundred and seventy thousand responses categorized in predefined categories of feedback. By doing the quantitative analysis of CFM data we have found that this particular e-governance project is reducing corruption of public officials and improving public service delivery. Further explanations are provided through information gathered by interviews. Finally we have tied our results to findings in the literature and suggested implications.

    Performance Evaluation and Comparison of Coherent and Incoherent Receivers under Atmospheric Turbulence2014Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [en]

    Optical free space communication system faces the major challenge because of the atmospheric condition. Signals receive in the ground station using two different types of receivers (Coherent detection and Intensity Modulation and Direct Detection (IM/DD)). Coherent detection uses PIN photo detector in the receiver end to attain the more sensitivity of the receiver. It receives the input data as a carrier signal and the local oscillator signal is mixed with the received signal and down convert the carrier signal to an intermediate frequency signal. The Intensity Modulation direct detection uses the Avalanche photo detector in the receiver end to attain the more sensitivity. This detection receives the input signal as a carrier signal and it is directly demodulated at the receiver back into the original signal. Signals receive in the ground station from the aircraft will be affected by the various types of noise like shot noise, thermal noise, etc. The occurrence of noises in the coherent detection is not exactly same as the IM/DD. Some noise get varies according to the electrical circuit noise produced in the receiver side. By deriving the signal-to-noise ratio, the background noise occur in the desired signal can be calculated. One of the main goals would be to derive a Probability Density Function (PDF) of the Signal-to-Noise Ratio (SNR) of the each type of receiver to check the efficiency of the receivers. Transmitting the optical signal from aircraft will face some data loss problem due to atmospheric turbulence disturbances, to identify the loss arises in the transmitting signal will be done by using the probability error method. Bit Error Rate (BER) derivation will take place to calculate and to identify the data loss occurs in the received signal. The project deals with measuring the efficiency and sensitivity among those two optical receivers and to check the robustness between those receivers against scintillations (power fades and surges) effects. In this work performance of the coherent receiver and IM/DD receiver using APD is compared with the different system characteristics. Sensitivity and performance of both the receivers are calculated with the same fading vector. Signal to noise ratio and bit error rate are theoretically derived and numerically analyzed in the case of atmospheric turbulence. Numerical results predict the performance of both the receivers.

    Urban Public Space: A Case from Developing Country2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Cities in developing world are inadequately equipped with public spaces. The increasing urbanizations trend is attracting more people to come to the cities without having proper sustainable plan for public spaces. However, this social public place holds the important function for urban well-being and collective recognition. This is the place where human can participate as fully fledged social subjects in complex civic life. Unfortunately, in most cases the provision of public space in these cities is always neglected or poorly integrated in planning legislations. So, in many cases community people make their own ways of social interaction that gives public space a new definition. Khulna, one of the divisional cities of Bangladesh, is going through the similar developing country situation. Lack of fund and space restricts development agencies to make new public spaces in this city. On the other hand management and coordination challenges between multilevel planning authorities also making existing public spaces malfunctioned. Sustainably planned, created and managed public spaces are hence urged for the cities of developing world to get livable and healthy urban environment.

    A dynamic hybrid antenna/relay selection scheme for the multiple-access relay channel2014In: 2014 11TH INTERNATIONAL SYMPOSIUM ON WIRELESS COMMUNICATIONS SYSTEMS (ISWCS), IEEE , 2014, 594-599 p.Conference paper (Refereed)
    Abstract [en]

    We propose a dynamic hybrid antenna/relay selection scheme for multiple-access relay systems. The proposed scheme aims to boost the system throughput while keeping a good error performance. By using the channel state information, the destination node performs a dynamic selection between the signals provided by the multi-antenna relay, located in the inter-cell region, and the relay nodes geographically distributed over the cells. The multi-antenna relay and the single-antenna relay nodes employ the decode-remodulate-and-forward and amplify-and-forward protocols, respectively. Results reveal that the proposed scheme offers a good tradeoff between spectral efficiency and diversity gain, which is one of the main requirements for the next generation of wireless communications systems.

    Lärande utvärdering: ESF-projektet Klara Livet : Implementeringsfasen 2013-20142014Report (Refereed)
    Abstract [en]

    Projekt Klara Livet har initierats av de problem och utvecklingsbehov som finns inom arbetslivet. Särskilt bekymmersamt är de människor som inte kommer in på arbetsmarknaden och att de individer som är eller har varit sjukskrivna kommer att bli/har blivit utförsäkrade från Försäkringskassan och inskrivna på Arbetsförmedlingen. Denna grupp arbetssökande har inte möjlighet att få tillträde till arbetsmarknaden på samma villkor som andra och har andra behov än friska arbetslösa. I Blekinge finns ett stort antal människor som befinner sig i denna situation. Under april 2010 hade 875 personer tidsbegränsad sjukersättning, fördelat på 656 kvinnor och 219 män. Vid årsskiftet 2009/2010 lämnade 212 personer sjukförsäkringen, något som resulterade i 187 arbetssökande. Efter tre månaders karens ansökte cirka hälften om förnyad sjukpenning. I februari 2010 fanns i länet 448 pågående ärenden som påbörjats sedan mer än ett år tillbaka. Således finns i Blekinge en relativt stor grupp människor som är eller riskerar att hamna i långvarigt utanförskap. Många i denna grupp har dessutom synliga eller dolda funktionsnedsättningar.

    Utvecklingsinriktat lärande inom ESF-projektet Klara Livet. Följeutvärderingsrapport2014Report (Other academic)
    Abstract [sv]

    Projekt Klara Livet riktar sig till individer med en svag ställning på arbetsmarknaden. Dessa väljs ut genom ett öppet ansökningsförfarande. Kärnverksamheten inom projektet är en intervention i form av en utbildningsinsats, som övergripande syftar till att stärka individens möjligheter och motivation att närma sig eller återgå till arbetet, fungera i vardagen och därigenom få ett större inflytande på sin upplevda hälsa. Projektets övergripande syfte är att genom otraditionellt samarbete mellan olika samverkansaktörer utarbeta och prova en alternativ modell för aktiv rehabilitering med arbetsförberedande insatser, som i förlängningen ska leda till sysselsättning för människor som riskerar att hamna i utanförskap. Ytterligare en målsättning är att individen ska närma sig arbetslivet och en egen försörjning, antingen genom arbetsplatspraktik eller genom introduktion till socialt eller kooperativt företagande. Generellt för den lärande utvärderingen i projekt Klara Livet är att evaluera projektets struktur, utfall och resultat av praktiskt arbete för att uppnå förändring, implementeringsprocesser och måluppfyllelse. Med denna utgångspunkt har en programlogisk teoribaserad utvärderingsmodell valts, som möjliggör en beskrivning av relationen mellan mål, aktiviteter, processer och effekter. Utvärderingsdesignen fokuserar på den lärande organisationen där gemensamt lärande, reflektion och kunskapsspridning i projekt Klara livet står i centrum och syftar till att skapa en utvecklad förståelse för användning och utveckling av den kunskap som projektet genererat. Ytterligare en ansats är att identifiera projektets programlogik och normativa teori med tonvikt på att tydliggöra kausaliteten mellan mål och aktiviteter, projektets framgångsfaktorer, nytänkande och innovativa idéer. En central fråga blir då om mål, verktyg och utfall hänger samman i logisk struktur. Rapporten bygger på cirka 200 sidor dokumentstudier, minnesanteckningar, processtöd till projektledare, kvalitetsansvarig och kursledare, 9 individuella intervjuer, 2 lärandeseminarier/dialog¬seminarier, 4 intervjuer i fokusgrupper, 1 workshop, 2 SWOT-analyser, 8 projektlednings¬möten, 1 styrgruppsmöte samt deltagande observationer i samband med möten och aktiviteter med kursledare och kursdeltagare. Resultatet visar att projektet följer de uppsatta direktiv från Europeiska Socialfonden och i väsentliga delar uppfyller projekt- och effektmålen. Projektets metodutveckling och de aktiviteter som genomförts inom projektet kan ses som ett mervärde till den arbetsmarknadspolitik som bedrivs av Arbetsförmedlingen och bör kunna medföra att den erfarenhet som finns inom projektet sprids till en strukturell nivå och på sikt bidrar till såväl systempåverkan, förändring och till offentlig debatt. Samtidigt finns en farhåga att Klara Livet inte implementeras, bedrivs för långt ifrån den reguljära verksamheten och därmed endast blir en tillfällig och tidsbegränsad lösning för en liten grupp individer. Fokus ligger på såväl individ som på samhällsnytta, sätter brukarperspektivet i centrum och har i princip nått ut till det antal kursdeltagare som planerats. En av projektets viktigaste framgångsfaktorer är den starka projektidén med utbildning och arbetsplatspraktik/socialt företagande, en kombination som bör stärka individens möjligheter att få ett arbete/närma sig arbetsmarknaden. Kursledarnas kompetens och engagemang, där många olika professioner och kompetenser samverkar, närhet till kursdeltagarna och individanpassning sammantaget med den metodutveckling som ägt rum i utbildningen är ytterligare framgångsfaktorer. Resultat och utfall på individnivå är i nuläget endast begränsade. Förbättringar i kategorierna allmän hälsa, psykisk hälsa, självkänsla, självförtroende, sovvanor, matvanor och hantering av symptom har påvisats med hjälp av Wilcoxon signed rank test. En svaghet är dock att mätningar vid baseline inte gjorts, varför dessa resultat måste betraktas som preliminära. Ytterligare en svaghet är att ingen forskning bedrivits inom projektet. Frågan om utbildningskonceptet leder till att de individer som deltagit i den riktade insatsen har närmat sig arbetslivet och fått större inflytande över sin upplevda hälsa bör därför fördjupas under den förlängda projekttiden september 2013-augusti 2014. En av utvärderingens viktigaste konklusioner är att för många deltagare har projektet varit en väg att komma vidare i en rehabiliteringsprocess med slutmålet att komma in på arbetsmarknaden. Innovativt är även de nya samarbetsformer som utvecklats under projekttiden. En utmaning inför den förlängda projekttiden är att ytterligare stärka och sedimentera den samverkan som byggts upp mellan myndigheter och andra aktörer, men även att pröva och ge alternativ till ordinarie strukturer och regelverk.

    Projekt Centrum för telemedicin: Följeutvärderingsrapport2014Report (Other academic)
    Abstract [en]

    Strukturfonderna är EU:s viktigaste verktyg för att minska regionala skillnader inom och mellan medlemsländerna. I den tredje programperioden, 2007-2013, satsas med nationell medfinansiering mer än 30 miljarder kronor i olika strukturfondsprojekt. Det ekonomiska stödet ska användas till insatser för regional utveckling, sysselsättning och kompetenshöjning i Sverige. Under programperioden har utvärderingsupplägget ändrats till "on-going evaluation", följeforskning, som syftar till att fortlöpande utvärdera projekten för få underlag till nya vägval och alternativa aktiviteter som bättre leder projekten mot effektmålen. Ytterligare förändring är att medlemsländerna ska visa att de utvecklar utvärderingskapacitet (evaluation capacity building) som kan ta sig an nya krav på följeforskning. Den europeiska kommissionen betonar även att erfarenheter och kunskaper från utvärderingsinsatserna kontinuerligt ska leda till lä-rande i program och projekt liksom till offentlig diskussion, public debate. I föreliggande slutrapport redogörs för den följeforskning som genomförts inom strukturfondsprojektet Centrum för Telemedicin, CTM under tiden 2012-2013 där syftet var att utvärdera projektets utveckling mot uppsatta mål. Centralt i denna lärande utvärdering har varit dialogen med projektledaren, projektdeltagarna och representanten för projektägaren. Rollen som följeforskare har inriktats på att vara stödjande, men också störande, det vill säga ifrågasättande och kritisk. Rapporten är indelad i fyradelar. Den första beskriver bakgrunden till projektet, dess syfte och mål. I den andra delen redogörs för följeforskningens metodologiska utgångspunkter och därefter redovisas resultatet i den tredje delen. I den avslutande delen förs ett framåtsyftande resonemang om vilka hållbara effekter som projektet bidragit med.

    Kartläggning av chefers vardag i Karlskrona kommuns samlade verksamheter2015Report (Other academic)
    Abstract [en]

    Bakgrund: En generell bild som ges av flera förvaltningar inom Karlskrona kommun är att arbetssituationen för många chefer, särskilt på mellannivå, är ohållbar. Denna bild har förstärkts av organisationens medarbetarundersökning 2013, men också av den genomgång av ledningsstrukturen vid Barn- och ungdomsförvaltningen, som utfördes 2014 av Ernst & Young Q1. Mot denna bakgrund har en kartläggning av kommunens samlade verksamheter initierats. Enligt projektplanen förväntas denna resultera i en tydlig beskrivning av innehållet i chefers vardag avseende ”arbetsuppgifter, beslutsunderlag och glädjeämnen samt ett förslag på åtgärder för att uppnå ett önskat läge avseende hållbara beslut, god arbetsmiljö, upplev arbetsglädje och hållbart ledarskap”.

    Measuring Disruptive Susceptibility: Insights from the ITS industry2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose. A small number of management theories have had as much influence in the business world as Clayton M. Christensen’s theory of disruptive innovation. Its key presupposition – that entrant companies with products or services that customers initially couldn’t use as it appears to have lower performance can supersede established companies – continues to create a significant impact on management practices and stimulate rich debate within academics. The goal of this thesis is to validate a specific framework available on the literature that assess the potential market entry of new companies as sources of disruptive innovations, named “disruptive susceptibility”, and gain new insights based on the findings of a qualitative study related to the Intelligent Transportation Systems (ITS) industry. Trending topics on this fast paced evolving industry, such as “Connected Cars” or “Autonomous Vehicles” are creating a high source of inspiration and new technologies are emerging to address new ITS industry’s needs.

    Methodology. Mixed methods research approach was applied utilizing convergent parallel mixed design. The research design process enabled an accurate confrontation of the disruptive susceptibility framework’s propositions against the target industry’s evidences collected from multiple relevant sources of evidences. Content validity and triangulation were applied to bring validity to the study.

    Theory. Disruptive innovation, Disruptive Susceptibility, Industry life-cycle.

    Conclusions. The disruptive susceptibility framework was validated for the ITS industry concluding that is a relevant instrument to identify and qualify the disruptive potential of new technologies. The results showed a high level of disruptive susceptibility in the ITS industry and the evidence gathered showed that conditional and accelerating propositions, when present, are most likely connected to an industry in a mature life-cycle stage. The study of the framework in further industries could provide more insights about this latter aspect. Furthermore, an additional proposition related to product life-cycles was proposed for the framework.

    The Role of Knowledge Management in Strategic Sustainable Development: Comparing Theory and Practice in Companies Applying the FSSD2016Independent thesis Advanced level (degree of Master (One Year)), 20 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to explore the role of knowledge management (KM) in integrating sustainability into business strategy in companies applying the framework for strategic sustainable development (FSSD).Corporations have the potential to be key players in moving society towards sustainability, but they lack clear definitions and guidelines around strategic sustainable development (SSD). The authors focus on the benefits of KM in organisations applying the FSSD, which offers general strategic guidelines, but does not refer to the complexity of managing the new sustainability knowledge.This study first examines the scientific literature around KM and FSSD and compares it with the results of expert interviews to develop a State of the Art Model of KM for SSD. Then the model is compared to current practices of corporations applying the FSSD and the gap is examined.The results of the analysis show that the concept of KM is widely discussed in the literature, yet it does not have much presence in the business world. The value of knowledge is recognised, but KM is not much used and no structured practices were identified. It was concluded that companies would benefit from a strategic KM system when integrating sustainability.

    Fuzzy Based power control system Using ANFIS and MIMO-OFDM Techniques in Cognitive Radio Networks2014Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [en]

    Cognitive Radio technology is used for efficient utilization of the spectrum. There are two types of users, one is the Primary user (PU), and the second one is the Secondary user (SU). In those users, PU is having the license to use the spectrum. The SU does not have the license to use the spectrum. Cognitive Radio comprises of Spectrum sensing, Spectrum Management and Spectrum Mobility. In cognitive radio, optimal power control in spectrum sharing is main research issues. In the spectrum, sharing both PU and SU can access the spectrum simultaneously as long as there is no interference to PU’s of Quality of service (QOS). So we have to handle this interference to the PU and we have to improve the performance of the SU. For that power control is the main consternate to improve the performance of SU. In our thesis, we are divided into two parts, the first one is we used ANFIS (Adaptive Neuro Fuzzy Inference System) for optimizing power control in cognitive radio network Users (SU) by optimization of SNR & SINR at Primary User (PU) to maintain QOS of PU and improve the performance of SU and Channel capacity computation for various ISR tolerance levels at PU. In second part, we used implementation of MIMO (Multiple Input Multiple output)-OFDM (Orthogonal Frequency Division Multiplexing) transmission technique in CRN (Cognitive Radio networks) for it is use in emergency conditions where transmission requires reliability and high data rate. Then it is tested BER (Bit error rate) performance on MATLAB. Key words: Cognitive Radio, Power Control, the Fuzzy Interference System (FIS), ANFIS, “MIMO” (“Multiple Input Multiple Output”), “OFDM” (“Orthogonal Frequency Division Multiplexing”), AWGN, BER, SNR, Eb/N0

    Att skapa ett varumärke: En granskning av hur Helsingborg framställs genom platsmarknadsföring2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    I föreliggande uppsats beskrivs platsmarknadsföring som fenomen och mer konkret studeras det hur platsmarknadsföringen framställts i Helsingborgs kommun. Arbetet undersöker således ett antal större projekt som kan kopplas till platsmarknadsföring. Med hjälp av en kvalitativ innehållsanalys har olika plandokument studerats. Den kvalitativa innehållsanalysen har utgått ifrån tre olika motsatspar och har genom detta kunnat synliggöra att där i det empiriska materialet finns en tonvikt mot tillämpade-, platsoberoende- och förändringsorienterade värden.

    Det studerade materialet uppvisar tendenser som kan kopplas till ekonomiska syften och där detta ofta ska uppnås genom förändring och med fokus på ett större perspektiv än den egna kommunen. Materialet uppvisar tendenser som går att koppla till en utåtriktad platsmarknadsföring. Vidare finns där tendenser i analysen som tyder på att där kan finnas en dold maktutövning, detta går dock inte att direkt bekräfta eller konstatera. Slutligen finns där tendenser som tyder på att globaliseringen och den uppfattade konkurrensen kan ha påverkat platsmarknadsföringen i Helsingborg. Detta gör att platsmarknadsföringen i kommunen stämmer överens med vad tidigare forskning på området kommit fram till, där globalisering och den upplevda konkurrensen ses som två faktorer som påverkar platsmarknadsföring

    Designing a Socially Sustainable Impact Sourcing Model for Integrating Immigrants in Sweden2017Independent thesis Advanced level (degree of Master (One Year)), 20 HE creditsStudent thesis
    Abstract [en]

    This research proposes a socially sustainable impact sourcing model (SSISM), pertinent to the field of socially responsible outsourcing and offers recommendations for integrating immigrants in Sweden by using this model. The model brings businesses, communities and people together to create benefits for all stakeholders in a sustainable way.

     

    Sweden has a long history of accepting immigrants, yet, has a comparably low success rate of integrating non-Swedish people into society. If SSISM is applied in Sweden, there is a potential for businesses to save money, for challenges like the integration problem to be mitigated, and for communities to benefit from an increased tax base as well as building stronger, more diverse communities.

     

    The universal model for SSISM was developed through the analysis of existing practices and the use of the Framework for Strategic Sustainable Development (FSSD), a sustainability planning tool. The research process included informal interviews with businesses, communities and government agencies, formal interviews with businesses, and a survey with immigrants. The interviews and survey helped maintain relevance to the Swedish context and identified potential obstacles and enablers for implementation. From the results, recommendations on how to best apply the model for integrating immigrants into Sweden were developed in the discussion.

The study aims to answer the question: How and why is thetemporary agency workers’ perceived fairness and motivation at work impacted by notreceiving any direct financial bonus from the user company?Method: We have conducted a qualitative approach and made the study within a chosencompany suitable for our purpose. The data have been collected through in-depth interviewsto be able to take part of the interview subjects’ opinions, attitudes and experiences.Results: The temporary agency workers experience a procedural and distributive injusticelinked to the financial bonus. However, no overall organizational injustice is experienced,which can be explained by the fact that the temporary agency workers as a whole experienceperceived fair treatment from the company. The perceived motivation is not affected by theexclusion from the financial bonus, due to the fact that the needs of the consultants associatedwith the work consist of the amount of work that is possible. The motivation is influenced bythe number of shifts and the opportunity to earn more money through more shifts.

    Understanding the Impact of Rewards on Employees’ Creativity and Innovation: a Literature Review Study2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The purpose of this master’s thesis is to study how organizational rewards; intrinsic rewards and extrinsic monetary and non-monetary rewards, affect employees’ creativity and innovation within an organizational environment, and to propose a new categorization of organizational rewards.

    Methodology: A literature review of selected peer-reviewed studies from different countries and industries.

    Findings: The results of this study support the following notions; (1) intrinsic rewards support employees’ creativity and innovation through their positive impact on intrinsic motivation; (2) extrinsic non-monetary rewards support employees’ creativity and innovation ; (3) extrinsic monetary rewards can support or hinder employees’ creativity and innovation depending on external organizational factors. This study suggests a new model which categorizes organizational rewards into two main groups; monetary and non-monetary instead of extrinsic and intrinsic, and the non-monetary one into intrinsic and extrinsic while the monetary group includes only extrinsic rewards.

    Bostadsmässor och den rättvisa staden: En studie av tre bostadsmässor2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Denna uppsats handlar om bostadsmässan som begrepp utifrån perspektivet den rättvisa staden. Uppsatsen bygger på fallstudier av tre bostadsmässor utifrån fall- studier. De tre studerade bostadsmässorna är Bo92, Bo01 och TenstaBo06. Syftet är att studera bostadsmässorna utifrån social och ekologisk hållbarhet och även ut- ifrån de krav som finns på hur det byggs studera påverkan på utformandet av bo- stadsmässorna ur ett socialt hållbarhetsperspektiv med fokus på rättvisa och mång- fald från teorin om den rättvisa staden. För att kunna besvara syftet och forsknings- frågorna har intervjuer och dokumentinläsning genomförts. Sju personer som på olika sätt har arbetat med eller har någon koppling till de tre bostadsmässorna har intervjuats. Dokumentstudier av olika material om bostadsmässorna har gjorts och analyserats tillsammans med de transkriberade intervjuerna.

    Analysen utgår från temana mångfald, rättvisa, ekologiska aspekter samt bland- stad. Temana mångfald och rättvisa kommer från teoridelen och utgör två teman som kan representera den rättvisa staden. Utöver de två nämnda temana har eko- logiska aspekter och blandstad ingått i analysen. Ekologiska aspekter och blandstad kan ses som två exempel på hur bostadsmässorna utformas och vad det har för påverkan på mångfald och rättvisa inom bostadsmässorna.

    Resultatet visar att bostadsmässor ofta har visat upp bostäder för en köpstark kundkrets och även fått kritik för det. Förklaringen kan vara att bostadsmässor har som syfte att vara en arena för innovationer och att visa på något nytt. Teman kring ekologiska lösningar syns mest i Bo92 och Bo01 som hade tydliga teman kring eko- logiska aspekter med innovativa lösningar. Temana mångfald och blandstad upp- fattas ofta som synonyma med varandra. Mångfald som begrepp nämns i större utsträckning än blandstad. Även om blandstad inte nämns specifikt så är det bland- stadens ideal som efterfrågas i planeringen av bostadsmässorna. Inom alla tre bo- stadsmässorna finns en uttalad önskan om mångfald och den uttrycks i en variation av byggnadstyper, kvarterstadideal och upplåtelseformer. Mångfalden kopplas mer till sammansättningen av människor som befolkar området. Alla tre bostadsmäs- sorna nämner en mångfald av olika grupper av människor som önskvärt och att det ska uppnås genom att erbjuda bostäder som skiljer sig åt när det kommer till ex- empelvis upplåtelseformer, boendestorlekar och boendekostnader.

    Bostadsmässorna som har studerats har byggt på liknande teman och bidragit till att det mestadels byggs bostäder som inte alla har råd med. Hållbarhet uttryckt i ekologisk och social hållbarhet har varit omnämnt i alla tre bostadsmässorna. Skill- naden är att Bo06 som inte har uttryckt något specifikt syfte att vara hållbar är den bostadsmässa som uppfattas som den mest hållbara.

    How to turn innovations into value in a large manufacturing company2014Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [en]

    Large companies invest a vast amount of capital and time on R&D annually. With all this financial investment in R&D, it is important that the companies get value for their invested capital. By creating innovations, such as new products and services, involve high risk and will necessarily not lead to successful commercial ends. Many companies lack the competencies in selecting ideas and transform them into value. Knowledge in innovations is affecting companies, especially those that are investing heavily in R&D. The present study explain how value can be created from innovation around the topics of innovativeness, innovation protection and market efficiency, within a large global manufacturing company in Sweden with global operations. A four dimensional measure from a prior study has been the base for the structural theoretical model that has been tested. The authors have divided innovativeness, innovation protection and market efficiency into absorptive capacity (ACAP), open innovation, patents, secrecy, lead time advantages and complementary assets and studied modern literature to find relationships between these and how it affects firm performance. They have also done a survey and interviews to examine the present status in a large manufacturing company. The empirical findings show support for a relationship between ACAP and firm performance, ACAP and success of strategic alliances as well as a relationship between protection of innovation and success of strategic alliances.

    Erfarenheter av att läsa sin patientjournal via Internet: En intervjustudie med personer som har diabetes2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Journalen via Internet ger den enskilda personen möjlighet att få en inblick i den vård och behandlingsplan som erbjudits och utförts. För distriktssköterskan som möter personer med diabetes är det av stor betydelse att bedriva en strukturerad diabetesvård innehållande vägledning mot goda levnadsvanor. Journalen kan för den enskilda personen resultera i att delaktigheten i sin sjukdom, egenvård och behandling ökar.

    Syfte: Syftet med studien var att beskriva personers erfarenheter av att läsa sin patientjournal via Internet.

    Metod: En kvalitativ intervjustudie med åtta deltagare har genomförts. Data samlades in med semistrukturerade intervjuer. Insamlat intervjumaterial analyserades utifrån Graneheim och Lundmans beskrivning av en kvalitativ innehållsanalys.

    Resultat: Resultatet utgörs av fyra huvudkategorier och åtta underkategorier. Huvudkategorin Stödjande verktyg för att inhämta information presenteras i två underkategorier, som beskriver Minnesstöd skapar trygghet och Vägledning för egenvård. Huvudkategorin Begränsningar i texten skapar oro presenteras i tre underkategorier, som beskriver Felskrivningar, Språkbruket försvårar förståelsen för texten samt Vårdpersonalens begränsade journalåtkomst. Huvudkategorin Att vidareutveckla journalsystemet med användaren som delaktig presenterar tre underkategorier, som beskriver Utökat kunskapsstöd ökar användbarheten, Effektivisering av ärendehantering samt Journalåtkomst länsöverskridande. Vidare beskrivs Betydelsen av datorvana vid journalhantering.

    Slutsats: Det beskrivs som betydelsefullt att få insyn i vad som skrivits i journalen samt insyn i den hanteringen som föreligger runt den enskilda personens ärende. Journalen beskrivs vara ett stödjande verktyg för personer där de efter önskemål inhämtar kunskap samt utläser den information som anses betydelsefull och intressant. Genom journaltexten kan personer vidare få vägledning i de egenvårdsåtgärder som anses mest lämpliga för hälsan. Funktioner och tjänster som idag innefattas i journalen behöver vidareutvecklas för att journalen ska kunna bli det kompletta verktyg som efterfrågas.

    Cooperative multiple-access scheme with antenna selection and incremental relaying2014In: 2014 INTERNATIONAL TELECOMMUNICATIONS SYMPOSIUM (ITS), São Paulo: IEEE , 2014Conference paper (Refereed)
    Abstract [en]

    A cooperative multiple-access scheme for wireless communications systems with antenna selection and incremental relaying is proposed. The scheme aims to improve the system throughput while preserving good performance in terms of bit error rate. The system consists of N nodes which send their information to both the destination node and the multiple-antenna relay station. Based on the channel state information, the destination node decides whether or not relaying will be performed. When the relaying is performed, the decode-remodulate-and-forward protocol is used with the best antenna. Results reveal that the proposed scheme achieves a good tradeoff between throughput and bit error rate, which makes suitable to be considered for multi-user networks.

    The Stories We Tell: Designing Values-Oriented Narratives of Radical Change Initiatives Towards Sustainability2014Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    While extensive communication around the sustainability challenges have lead to increased awareness, the expected behavior change correspondent to that level of awareness has not been observed. After decades of information-based sustainability communication the research community recognizes values as important drivers of peoples behavior. Consequently, communication needs to be designed intentionally, so as to implement the change necessary in order to shift society to a sustainable level where the global community lives within the planetary boundaries. This thesis was inspired by this call from the field of sustainability science for a new narrative around sustainability that would inspire more radical change. In the first step we used the European Citizens ́ Initiative for an Unconditional Basic Income (EUBI) as a case study, to analyze what types of values the current narrative of the EUBI speaks to and compare that with the values of the population of the European Union. In the second step our research focused on what types of Guidelines could be developed so as to intentionally design a values-oriented narrative. We identified three ways in which the narrative of EUBI is misaligned with the values of the population of the European Union. We identified as well 13 Guidelines for designing a values-oriented narrative that could contribute in moving society strategically towards sustainability. When utilizing the Guidelines as a tool in crafting a potentially more successful narrative as part of a new sustainability communication, the contribution to SSD may be to strategically overcome the above described misalignment and inspiring more action to bridge the gap.

    Visualizing Material on Site for Machines and Humans: A Step toward an Autonomous Construction Site2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The construction industry has not seen the same growth in productivity as e.g. the manufacturing- and automobile industry. This is largely due to the ease of implementing automation and robotics in the latter mentioned industries. Now more than before when the urbanization rate is increasing, there is a strong need in increasing the efficiency of the construction industry. That is why the research questions of this thesis work involves finding a complementary solution that will help autonomous construction machines operate in a dynamic construction site. The aim is permeated by two visions. The first one being to have autonomous construction machines collaborating with humans in the most remote places in the world. The second vision is that multiple smaller construction machines is more beneficial. Meaning a few machine breakdowns would not halt the entire construction process.

    During the research work, using the design research methodology and the innovation process, data showed that a construction site is very dynamic and complex. Having a change in factors such as size of construction site, number of involved stakeholders, location of the construction site, and time phase heavily affects the complexity of the site. Throughout the three case studies there were different characteristics, but there was a pattern. All the mentioned factors played a huge role in what needs expressed by the interviewees. The more complex a site was, the more there was a need to organize the material, personnel and machine flow. Therefore, the final solution is to decentralize the information flow of the construction site. Meaning that all humans, machines and material on site is to communicate its information. The suggested solution is the usage of a tag using GPS and Wi-Fi to communicate location and the necessary information. Thus, when attaching the tag onto a material, the workers and the machine will know of its information.

    The analogy is that when the implementation of autonomous machines is up to pace, the sites need to be prepared with all the errors and issues that might come with it. Since the autonomous construction machines will be collaborating with humans, it means that the issues expressed today will reappear in the future. Also, since the implementation of autonomy and robotics has been slow for the construction industry, there is a clear need of a complementary solution to speed up the process. By decentralizing the construction site and implementing tags on each interesting point, the once complex and changing construction site, will turn into a fully digitized infrastructure.

    Facebook Blocket with Unsupervised Learning2014Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [en]

    The Internet has become a valuable channel for both business-to- consumer and business-to-business e-commerce. It has changed the way for many companies to manage the business. Every day, more and more companies are making their presence on Internet. Web sites are launched for online shopping as web shops or on-line stores are a popular means of goods distribution. The number of items sold through the internet has sprung up significantly in the past few years. Moreover, it has become a choice for customers to do shopping at their ease. Thus, the aim of this thesis is to design and implement a consumer to consumer application for Facebook, which is one of the largest social networking website. The application allows Facebook users to use their regular profile (on Facebook) to buy and sell goods or services through Facebook. As we already mentioned, there are many web shops such as eBay, Amazon, and applications like blocket on Facebook. However, none of them is directly interacting with the Facebook users, and all of them are using their own platform. Users may use the web shop link from their Facebook profile and will be redirected to web shop. On the other hand, most of the applications in Facebook use notification method to introduce themselves or they push their application on the Facebook pages. This application provides an opportunity to Facebook users to interact directly with other users and use the Facebook platform as a selling/buying point. The application is developed by using a modular approach. Initially a Python web framework, i.e., Django is used and association rule learning is applied for the classification of users’ advertisments. Apriori algorithm generates the rules, which are stored as separate text file. The rule file is further used to classify advertisements and is updated regularly.

    Robust Image Hash Spoofing2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    With the intensively increasing of digital media new challenges has been created for

    authentication and protection of digital intellectual property. A hash function extracts certain

    features of a multimedia object e.g. an image and maps it to a fixed string of bits. A perceptual

    hash function unlike normal cryptographic hash is change tolerant for image processing

    techniques. Perceptual hash function also referred to as robust hash, like any other algorithm is

    prone to errors. These errors are false negative and false positive, of which false positive error is

    neglected compared to false negative errors. False positive occurs when an unknown object is

    identified as known. In this work a new method for raising false alarms in robust hash function is

    devised for evaluation purposes i.e. this algorithm modifies hash key of a target image to

    resemble a different image’s hash key without any significant loss of quality to the modified

    image. This algorithm is implemented in MATLAB using block mean value based hash function

    and successfully reduces hamming distance between target image and modified image with a

    good result and without significant loss to attacked imaged quality.

    Symmetries and conservation laws of the generalized Krichever-Novikov equation2016In: Journal of Physics A: Mathematical and Theoretical, ISSN 1751-8113, E-ISSN 1751-8121, Vol. 49, no 10, 105201Article in journal (Refereed)
    Abstract [en]

    A computational classification of contact symmetries and higher-order local symmetries that do not commute with t, x, as well as local conserved densities that are not invariant under t, x is carried out for a generalized version of the Krichever-Novikov (KN) equation. Several new results are obtained. First, the KN equation is explicitly shown to have a local conserved density that contains t, x. Second, apart from the dilational point symmetries known for special cases of the KN equation and its generalized version, no other local symmetries with low differential order are found to contain t, x. Third, the basic Hamiltonian structure of the KN equation is used to map the local conserved density containing t, x into a nonlocal symmetry that contains t, x. Fourth, a recursion operator is applied to this nonlocal symmetry to produce a hierarchy of nonlocal symmetries that have explicit dependence on t, x. When the inverse of the Hamiltonian map is applied to this hierarchy, only trivial conserved densities are obtained.
