    Collaboration Between Children: working with the educational software Quest Atlantis2004Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [en]

    Will the different levels of knowledge contribute to a collaborative learning? This thesis is based on a tuition experiment with children in small groups, working with the educational software Quest Atlantis at Kensington Park Elementary school in Miami. During this research we have found some similarities and new concepts within Damon’s and Phelps’s three peer learning concepts (1989). Through our investigation of how children collaborate and learn from each other, we discovered that anyone could be a contributor to the collaboration. Through our transcription we defined and measured patterns of collaboration between the pupils, which we used to identify how the pupils collaborated. Out of this we constructed two new concepts, Temporary Expert and Concealed Contributor, which affects the collaboration in different ways.

    EDI eller ebXML: för automatisering av affärsprocesser2001Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Sammanfattning EDI är ett välkänt och beprövat sätt för företag att automatisera sina affärsprocesser. Det är också välkänt att EDI är dyrt att både inverstera i och att använda. EDI anses också som krångligt att lära sig och att förstå. Detta har gjort att EDI aldrig riktigt har slagit igenom bland små och medelstora företag. Det internationella standardiseringsprojektet ?ebXML?, som sponsras av bland annat av UN/CEFACT och OASIS, har släppt ett ramverk för hur XML ska kunna användas för elektronisk handel, även B2B. Visionen för ebXML är att det ska vara en enkel global standard som ska kunna användas av alla, även små och medelstora företag. Syftet med uppsatsen är att ge en vägledning för små och stora företag vilket av EDI och ebXML som skulle vara bäst för just deras företag. För att få fram detta har vi utgått från fyra olika kriterier, marknadsnisch, kundrelationer, ekonomi och kompetens. Sedan har vi analyserat små företag för både EDI och ebXML i varje kriterium och stora företag för både EDI och ebXML i varje kriterium. Efter varje del har vi gjort en bedömning om hur väl EDI eller ebXML stämmer överens med de krav som finns för företaget under respektive kriterium och gjort en poängbedömning från 1 ? 4, där 4 är bäst. Slutsatsen av analysen blev att för små företag är ebXML bäst, då EDI både är dyrt och kompetenskrävande, vilket kan vara svårt för små företag att klara av. Vår slutsats stämmer väl överens med både visionen för ebXML och erfarenheten som finns kring användandet av EDI. Slutsatsen för stora företag blev ingen markant fördel för något av alternativen. De båda alternativen fick nästan lika många poäng. Stora företag får se vilka kriterier som är viktigast för just deras företag och göra bedömningen utifrån detta. Vi konstaterar också att det finns andra aspekter att titta på när man väljer mellan EDI och ebXML. Det vi trycker mest på är säkerheten som vi inte behandlat i denna uppsats men som är ett viktigt område. Slutligen konstaterar vi att om visionen för ebXML uppfylls så kommer ebXML att bli revolutionerande för utvecklingen av B2B.

    An Exploration of Strategic Sustainable Development (SSD) Complemented Transformative Social Innovation (TSI) Tools2018Independent thesis Advanced level (degree of Master (One Year)), 20 HE creditsStudent thesis
    Abstract [en]

    The human social system is facing complex social issues and (new) initiatives coming from different social actors are born to try to tackle these complex social issues. Social innovation is the field where these initiatives function, so it is also a complex field to identify and frame. Thus a new theory, the Transformative Social Innovation Theory (TSI), was developed in order to frame and bring more clarification on the social innovation field to contribute to societal transition and transformation. The five TSI tools were developed from the TSI theory and they are training tools. All the TSI tools aim to (dis)empower the social innovation initiatives, actors and networks in the process of transformative social innovation. Transformative Social Innovation is the process of changes in social relations involving challenging, altering and/or replacing dominant institutions and structures which are considered to be the roots of systemic errors. This study sought to explore the Transformative Social Innovation tools from the perspective of the Strategic Sustainable Development (SSD). In this regard, the Framework for Strategic Sustainable Development (FSSD) was adopted as it provides a principle-based and scientifically-proved definition of sustainability as well as a systems thinking approach regarding the complexity of global sustainability challenges. This research project tried to identify the potential contributions of the TSI tools to sustainability and the entry points of the tools where relevant SSD features could complement them so that they can contribute to strategically move the society towards sustainability. A qualitative research approach was selected. The methodology included four research methods, namely document content analysis, interviews, the FSSD analysis and prototyping. The results of this research indicated three main contributions of the TSI tools that could help to strategically move the society towards sustainability. Five entry points where the tools could be complemented with SSD features and a set of add-ins from SSD that could complement the current TSI tools were identified. The add-ins were sent to the TSI theory authors for the expert consultation.

    Carbon Neutrality as Leverage in Transitioning a Financial Organisation Towards Sustainability2006Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Climate change is one of the most pressing environmental issues of our time, as it threatens the survival of human civilisation. With the increasing number of initiatives trying to address climate change, it is important to examine how effective they are and what other roles these initiatives can serve in transitioning society towards sustainability. This thesis investigates the role of one such initiative, carbon neutrality, within a strategic approach to sustainable development, based on the case study of the North American Credit Union (NACU). A scientific understanding of climate change and sustainability provide a strict evaluation of the carbon neutrality concept with its benefits and challenges, including the role of carbon offsets. Within this context, recommendations are provided for roles and actions that a financial organisation such as NACU can take in order to set high standards in this new and still evolving market of voluntary carbon offsets, while striving for full sustainability and leadership within the community.

    Att Bygga Broar -att som sjuksköterska skapa en förtroendefull kontakt med en skadad person prehospitalt2001Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Det krävs mycket av en sjuksköterska för att kunna skapa tillit och förtroende prehospitalt med en skadad person. Syftet har varit att undersöka vilka faktorer/åtgärder/förhållningssätt som krävs av en sjuksköterska i första mötet med en skadad person för att skapa en förtroendefull och kontakt med känsla av tillit. Undersökningen har genomförts som en litteraturstudie och resultatet visar på att om en förtroendefull kontakt ska skapas mellan sjuksköterskan och en skadad person prehospitalt krävs det framför allt att en kommunikation dem emellan kommer till stånd. Andra slutsatser i resultatet är att en sjuksköterska måste utföra vissa kommunikationsstrategier för att en kontakt ska uppstå. De kommunikationsstrategier som är väsentliga för att skapa en förtroendefull kontakt är bland andra sjuksköterskans förhållningssätt samt att sjuksköterskan har självinsikt och kunskap om effekter av ett sitt agerande. Slutsatsen blev att sjuksköterskan bör känna till sitt eget samt sin patients kroppsspråk så att missförstånd i kontakten undvikes. Sjuksköterskan bör känna empati och kunna avgöra när han gör intrång i patientens privata utrymme. Sjuksköterskan ska därför vara noga med att röra vid patienten med eftertanke. Det är även av stor vikt att sjuksköterskan informerar patienten om läget/ situationen och förklarar vad som sker för att tillit och förtroende ska kunna skapas.

    Measurements and Models of One-Way Transit Time in IP Routers2005Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The main goals of this thesis are towards an understanding of the delay process in best-effort Internet for both non-congested and congested networks. A novel measurement system is reported for delay measurements in IP routers, which follows specifications of the IETF RFC 2679. The system employs both passive measurements and active probing and offers the possibility to measure and analyze different delay components of a router, e.g., packet processing delay, packet transmission time and queueing delay at the output link. Dedicated application-layer software is used to generate UDP traffic with TCP-like characteristics. Pareto traffic models are used to generate self-similar traffic in the link. The reported results are in form of several important statistics regarding processing and queueing delays of a router, router delay for a single data flow, router delay for multiple data flows as well as end-to-end delay for a chain of routers. They confirm results reported earlier about the fact that the delay in IP routers is generally influenced by traffic characteristics, link conditions and, to some extent, details in hardware implementation and different IOS releases. The delay in IP routers may also occasionally show extreme values, which are due to improper functioning of the routers. Furthermore, new results have been obtained that indicate that the delay in IP routers shows heavy-tailed characteristics, which can be well modeled with the help of several distributions, either in the form of a single distribution or as a mixture of distributions. There are several components contributing to the OWTT in routers, i.e., processing delay, queueing delay and service time. The obtained results have shown that, e.g., the processing delay in a router can be well modeled with the Normal distribution, and the queueing delay is well modeled with a mixture of Normal distribution for the body probability mass and Weibull distribution for the tail probability mass. Furthermore, OWTT has several component delays and it has been observed that the component delay distribution that is most dominant and heavy-tailed has a decisive influence on OWTT.

    Overlay Multicast Networks: Elements, Architectures and Performance2007Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Today, the telecommunication industry is undergoing two important developments with implications on future architectural solutions. These are the irreversible move towards Internet Protocol (IP)-based networking and the deployment of broadband access. Taken together, these developments offer the opportunity for more advanced and more bandwidth-demanding multimedia applications and services, e. g., IP television (IPTV), Voice over IP (VoIP) and online gaming. A plethora of Quality of Service (QoS) requirements and facilities are associated with these applications, e. g., multicast facilities, high bandwidth and low delay/jitter. Moreover, the architectural solution must be a unified one, and be independent of the access network and content management. An interesting solution to these challenges is given by overlay multicast networks. The goal of these networks is to create and to maintain efficient multicast topologies among the multicast participants as well as to minimize the performance penalty involved with application layer multicasting. Since they operate at the application layer, they suffer from two main drawbacks: higher delay and less efficient bandwidth utilization. It is therefore important to assess the performance of overlay multicast networks in “real- world”-like conditions. For this purpose, we first performed an in-depth measurement and modeling study of the packet delay at the network layer. The reported results are in the form of several important statistics regarding processing and queueing delays of a router. New results have been obtained that indicate that the delay in IP routers shows heavy-tailed characteristics, which can be well modeled with the help of several distributions, in the form of a single distribution or as a mixture of distributions. There are several components contributing to the delay in routers, i. e., processing delay, queueing delay and service time. It was observed that the component delay distribution that is most heavy-tailed has a decisive influence on delay. Furthermore, we selected three representative categories of overlay multicast networks for study, namely Application Level Multicast Infrastructure (ALMI), Narada and NICE is the Internet Cooperative Environment (NICE). The performance of these overlay multicast protocols was evaluated through a comprehensive simulation study with reference to a detailed set of performance metrics that captured application and network level performance. A particular interest was given to the issues of scalability, protocol dynamics and delay optimization as part of a larger problem of performance-aware optimization of the overlay networks. The simulations were configured to emulate “real-world”-like characteristics by implementing a heavy-tailed delay at the network level and churn behavior of the overlay nodes. A detailed analysis of every protocol is provided with regard to their performance. Based on our study, significant conclusions can be drawn regarding the scalability of the protocols with reference to overlay multicast group management, resource usage and robustness to churn. These results contribute to a deeper understanding of the requirements for such protocols targeted at, e. g., media streaming.

    One-Way Transit Time Measurements2004Report (Refereed)
    Abstract [en]

    This report is a contribution towards a better understanding of traffic measurements associated with e2e delays occurring in best-effort networks. We describe problems and solutions associated with OWTT delay measurements, and give examples of such measurements. A dedicated measurement system is reported for delay measurements in IP routers, which follows specifications of the IETF RFC 2679. The system uses both passive measurements and active probing. Dedicated application-layer software is used to generate traffic. Pareto traffic models are used to generate self-similar traffic in the link. Both packet inter-arrival times and packet sizes are matching real traffic models. A passive measurement system is used for data collection that is based on using several so-called Measurement Points, each of them equipped with DAG monitoring cards. Hashing is used for the identification and matching of packets. The combination of passive and active measurements, together with using the DAG monitoring system, gives us an unique possibility to perform precise traffic measurements as well as the flexibility needed to compensate for the lack of analytic solutions. The real value of our study lies in the hop-by-hop instrumentation of the devices involved in the transfer of IP packets. The mixture of passive and active traffic measurements used, allows us to study changes in traffic patterns relative to specific reference points and to observe different contributing factors to the observed changes. This approach offers us the choice of better understanding diverse components that may impact on the performance of packet delay as well as to to measure queueing delays in operational routers.

    Congestion and Error Control in Overlay Networks2007Report (Other academic)
    Abstract [en]

    In recent years, Internet has known an unprecedented growth, which, in turn, has lead to an increased demand for real-time and multimedia applications that have high Quality-of-Service (QoS) demands. This evolution lead to difficult challenges for the Internet Service Providers (ISPs) to provide good QoS for their clients as well as for the ability to provide differentiated service subscriptions for those clients who are willing to pay more for value added services. Furthermore, a tremendous development of several types of overlay networks have recently emerged in the Internet. Overlay networks can be viewed as networks operating at an inter-domain level. The overlay hosts learn of each other and form loosely-coupled peer relationships. The major advantage of overlay networks is their ability to establish subsidiary topologies on top of the underlying network infrastructure acting as brokers between an application and the required network connectivity. Moreover, new services that cannot be implemented (or are not yet supported) in the existing network infrastructure are much easier to deploy in overlay networks. In this context, multicast overlay services have become a feasible solution for applications and services that need (or benefit from) multicast-based functionality. Nevertheless, multicast overlay networks need to address several issues related to efficient and scalable congestion control schemes to attain a widespread deployment and acceptance from both end-users and various service providers. This report aims at presenting an overview and taxonomy of current solutions proposed that provide congestion control in overlay multicast environments. The report describes several protocols and algorithms that are able to offer a reliable communication paradigm in unicast, multicast as well as multicast overlay environments. Further, several error control techniques and mechanisms operating in these environments are also presented. In addition, this report forms the basis for further research work on reliable and QoS-aware multicast overlay networks. The research work is part of a bigger research project, "Routing in Overlay Networks (ROVER)". The ROVER project was granted in 2006 by EuroNGI Network of Excellence (NoE) to the Dept. of Telecommunication Systems at Blekinge Institute of Technology (BTH).

    Implementation of Application Layer Multicast in OverSim2007Conference paper (Refereed)
    Abstract [en]

    This paper presents an overview of the implementation of Application Layer Multicast (ALM) in OverSim, a simulation framework designed specifically for simulating overlay networks. OverSim builds upon the OMNeT++ discrete event simulator. In addition, the paper presents guidelines for further research work based on reliable and Quality of Service (QoS)-aware multicast overlay networks. This research work is part of a bigger research project, called "Routing in Overlay Networks (ROVER)" which is focused on unicast and multicast routing in overlay networks with QoS guarantees and congestion control facilities on top of existing and future Peer-to-Peer (P2P) networks.

    On the Performance of Overlay Multicast Networks2008Conference paper (Refereed)
    Abstract [en]

    The paper reports on a performance study of several Application Layer Multicast (ALM) protocols. Three categories of overlay multicast networks are investigated, namely Application Level Multicast Infrastructure (ALMI), Narada and NICE is the Internet Cooperative Environment (NICE). The performance of the overlay multicast protocols is evaluated with reference to a set of performance metrics that capture both application and network level performance. The study focuses on the control overhead induced by the protocols under study. This further relates to the scalability of the protocol with increasing number of multicast participants. In order to get a better assessment of the operation of these protocols in "real-life"-like conditions, we implemented in our simulations a heavy-tailed delay at the network level and churn behavior of the overlay nodes. Our performance study contributes to a deeper understanding and better assessment of the requirements for such protocols targeted at, e.g., media streaming.

    Measuring perceived organizational support in a culturally and contractually diverse organization2012Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Subcontracting is an option available to modern organizations that aim to enhance their competitive position via the use of externally employed resources. While organizations try to become more productive and cost efficient in their outsourcing efforts the question of a possible impact of cultural and employment differences on organizational support, employee commitment and subsequently organizational performance remain suitable. This thesis investigates the impact of cultural distance and subcontractor distance on perceived organizational support. Perceived organizational support is considered amongst the key factors in the social exchange between employees and their employer and directly impacts employee commitment, attitudes and organizational performance. This research investigates how organizational supports provided by an engineering company in Denmark and its vendor are perceived by the two groups of culturally and contractually diverse employees. Both sets of employees were surveyed and the results were compared against stated hypotheses. Data for this research was collected through a questionnaire survey from a sample of subcontracted foreign employees and host employees. Several semi structured interviews were also conducted with the host organization employees and subcontracted foreign employees in order to ensure a quality verification of the data received from the survey. The findings of the study suggest that there is no direct link between perceived organizational support and cultural distance as the results of the subcontracted foreign employees are equivalent to those received from their Danish counterparts. Surprisingly, perceived organizational support of subcontracted employees rated higher towards the host organization than towards the vendor organization, their immediate employer. The current research provides supporting evidence that subcontracted foreign employees have dual commitment to both organizations, with higher level of commitment to the host organization. The proposed hypotheses were not confirmed. The results suggest that cultural distance has no significant impact on perceived organizational support for both the host and vendor organization employees. The study extends our understanding of organizational commitment that organizations can obtain from their contingent employees and the empirical findings provide us with a better understanding of the methods that can be used to achieve organizational goals. In summary, although organizations have to be mindful of possible challenges that outsourcing arrangements may bring due to cultural and contractual differences, there is no direct evidence of cultural distance impacting on employee attitude and commitment in this scenario. Organizational support provided by organizations will be perceived and appreciated regardless of cultural differences and employment status of its permanent and contingent employees.

    Selecting the Right Strategy: How are user innovations linked to the product life cycle for mature industries2016Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Companies are dependent on continuously provide the market with new products to keep its market position and profitability level. The companies examined in this thesis are two bigger Swedish enterprises that have a long history in a mature business-to-business context providing industrial goods to the market. This work examines how users are involved in the different innovation and product development activities. The problem is to understand how business-to-business companies co-operate with stakeholder and users, when in the product life cycle that is done, and who are the ones doing the actual innovation. The methodological approach for the work was deductive, building a theory including innovation, strategy and user theories that was empirically tested and followed by an analysis and conclusion of the found evidence. Key findings: Most if not all innovations in mature market are routine ones. There is lack of strategic focus due to micromanagement that shifts focus rapidly. Innovations are often found in the beginning and in the end of the product life cycle. Mature markets tend to utilize a more closed innovation model as opposite to an open model. Users are not heavily involved in the actual innovation process. Stickiness and tacit knowledge is quite big in large corporation event though there is said to be a strategic focus on the customers. Implications: More involvement of users, especially lead users, will lead to more innovations. Utilising strategic buckets of different sizes for spreading the resources on different innovation types (routine/disruptive/discontinuous) to become successful

    Finanskris & lågkonjunktur – konsekvenser för åkerier och dess anställda2009Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [sv]

    Generellt gäller att den undersökta branschen har blivit ganska så hårt påverkad av finanskrisen och lågkonjunkturen. De flesta åkerier har tvingats säga upp personal och även sänkningar av antal arbetstimmar förekommer. Omplaceringar är inte så vanliga inom populationen och det lutar åt att de mindre åkerier klarat sig lindrigare undan än vad de större har gjort. De åkerier som har varit i branschen en längre tid verkar också vara mindre känsliga för marknadsförändringar. Framtidsbilden ur åkarnas ögon ser mestadels stabil eller positiv ut medan investeringsviljan i branschen har avtagit då majoriteten nu är mer försiktiga än vad de varit tidigare.

    Attityder och varumärkeslojalitet inom snabbmatsbranschen2004Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Syfte: Syfte med arbetet är att undersöka vilken attityd studenterna har till snabbmat och att därutöver klarlägga om det råder någon varumärkeslojalitet hos de svenska studenterna inom snabbmatsbranschen. Uppsatsen ska ge en ökad förståelse för vilken roll ett varumärke spelar hos de svenska studenterna och se om det kan generera kundlojalitet. Den ska också medföra ökad förståelse för vilken attityd studenter har mot den i dagsläget mycket omdebatterade snabbmaten. Förutom det nyss nämnda syftar arbetet även till att förklara vilka faktorer som verkar vara viktiga för lojalitetsskapandet bland gruppen som studeras. Resultatet av undersökningen kan ge intressant och relevant information till företag och alla andra intressenter inom snabbmatsbranschen som kan ha nytta av uppsatsen för att lättare förstå studenter som en kundgrupp men även i skapandet av olika lojalitetsprogram som kan attrahera studenter. Metod: Som metod för insamling av empirin användes enkätundersökning som bestod av 210 enkäter insamlade i Malmö och Ronneby. Utdelningen av enkäterna skedde för hand på de två orternas högskoleområden. Enkäten bestod av fjorton frågor vars svar sedan sammanställdes i statistikdataprogrammet SPSS. Slutsatser: Generellt gäller att den undersökta målgruppen är kraftigt olojal och att varumärken inte verkar spela någon större roll vid köp av snabbmat. Anledningen verkar finnas i att studenter som individer ofta är variationssökare och gärna byter mellan märken. De flesta studenter är medvetna om den aktuella samhällsdebatten gällande snabbmat, men deras attityd verkar inte ha ändrats på grund av den.

    Fysisk aktivitet i fysisk planering2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Utvecklingen av dagens städer sker idag främst genom förtätning vilket skapar konkurrens mellan marken och olika intressen. I stora och växande städer finns få ytor kvar att exploatera och utveckla vilket gör att planeringen av dessa platser behöver vara väl genomtänkta för att kunna användas på ett så effektivt sätt som möjligt. Ofta finns det många intressen att utveckla dessa platser i olika riktningar vilket gör att vissa intressen få stå tillbaka för större intressen. Då platserna för fysisk aktivitet är viktiga för befolkningens hälsa är det viktigt att de får plats i staden och inte hamnar i bakgrunden utan planeras för med samma villkor som annan byggd miljö.

    Uppsatsen belyser hur två av Sveriges tre största städer hanterar dessa skilda intressen samt hur de arbetar för att skapa miljöer som främjar fysisk aktivitet hos befolkningen. Även vem som har ansvar för att det planeras för att främja fysisk aktivitet tas upp och studeras i uppsatsen.

    The increased mobility in society has led to a need for convenient mobile communication in many different type of environments. Environments such as a motorcycle helmet, engine rooms and most industrial sites share a common challenge in that they often offer significant acoustic background noise. Noise reduces the speech intelligibility and consequently limits the potential of mobile speech communications. Existing single channel solutions for speech enhancement may perform adequately when the level of noise is moderate. When the noise level becomes significant, additional use of the spatial domain in order to successfully perform speech enhancement is a potential solution. This is achieved by including several microphones in an array placed in the vicinity of the person speaking. A beamforming algorithm is hereby used to combine the microphones such that the desired speech signal is enhanced. The interest in using microphone arrays for broadband speech and audio processing has increased in recent years. There have been a considerable amount of interesting applications published using beamforming techniques for hands-free voice communication in cars, hearing-aids, teleconferencing and multimedia applications. Most of proposed solutions deal exclusively with environments where the noise is moderate. This thesis is a study of noise reduction in a helmet communication system on a moving motorcycle. The environment is analyzed under different driving conditions and a speech enhancement solution is proposed that operates successfully in all driving conditions. The motorcycle environment can exhibit extremely high noise levels, when driving at high speed, while it can produce a low noise levels at moderate speeds. This fact implies that different solutions are required. It is demonstrated in the thesis that a cascaded combination of a calibrated subband beamforming technique, together with a single channel solution provides good results at all noise levels. The proposed solution operates in the frequency domain, where all microphone signals are decomposed by a subband filter bank prior to the speech enhancement processing. Since the subband transformation is an important component of the overall system performance, a method for filter bank design is also provided in the thesis. The design is such that the aliasing effects in the transformations are minimized while a small delay of the total system is maintained.

    Microphone array system for speech enhancement in a motorcycle helmet2005Report (Other academic)
    Abstract [en]

    In this report a real case study of the sound environment within a helmet while driving motorcycle is investigated. A solution to perform speech enhancement is proposed for the purpose of mobile speech communication. A microphone array, mounted onto the face shield in front of the user's mouth, is used to capture the spatio-temporal properties of the acoustic wave ¯eld inside the helmet. The power of the spatially spread noise within the helmet is small when standing still while it may heavily exceed the power of the speech when driving at high speeds. This will result in dramatically reduced speech intelligibility in the communication channel. The highly dynamic noise level imposes a challenge for existing speech enhancement solutions. We propose a subband adaptive system for speech enhancement which consists of a soft constrained beamformer in cascade with a signal-to-noise ratio dependent single microphone solution. The beamformer make use of a calibration signal gathered in the actual environment from the speaker's position. This calibration procedure e±ciently captures the acoustical properties in the environment. Evaluation of the beamformer and the single microphone algorithm, both as either parts by them selves and as a cascaded structure, together with the optimal subband Wiener solution is presented. It is shown that a cascaded combination of the calibrated subband beamforming technique together with the single channel solution outperforms either one by it self, and provides near optimal results at all noise levels.

    A Spatially Constrained Subband Beamforming Algorithm for speech enhancement2004Conference paper (Refereed)
    Abstract [en]

    This paper discusses speech enhancement in an enclosed environment such as communication in a motorcycle helmet. A new constrained subband adaptive beamformer is proposed, which uses the concept of an earlier proposed calibrated beamformer mainly developed for a hands-free in-car environment. The highly non-stationary nature of the disturbing sound field encountered in an motorcycle helmet and the fact that the source is situated in the extreme nearfield of the array, causes the beamformer to produce an unwanted fluctuation in the output level. The spatially constrained beamformer proposed in this paper makes sure that the output maintains a constant gain, as long as the corresponding source originates from the desired location.

    Människans interaktion med miljön2010Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Denna uppsats är en beskrivning och undersökning på vad utemiljön har för betydelse för oss som individer och hur den påverkar oss. Uppsatsen kommer först att gå igenom en litteraturgenomgång, sedan görs en analys av två bostadsområden i Kristianstad och därefter presenteras en intervjuundersökning som har gjorts på respektive bostadsområde. Utefter de slutgiltiga resultaten kommer uppsatsen att avslutas med en diskussion och slutsats. Enligt bl.a. Karla Werner (Olsson m.fl. 1998), Kevin Lynch (1977) och Patrik Grahn (Olsson m.fl.) föredrar människan platser där denne känner sig hemma och kan skapa sig en egen identitet. Även Maria Nordström (Olsson m.fl. 1998) betonar hur människan kan skapa sig en identitet i utemiljön. Men hon påpekar istället att detta sker först och främst under vår barndom. Boverket (1994:12) skriver också om identiteten, men i detta fall är det grönskan de skriver om. De menar att det är grönskan som ger en karaktär och identitet till staden, även Grahn (1986) antyder på detta. Lynch (1977), Grahn (Olsson m.fl. 1998) och Nordström (Olsson m.fl.) skriver om hur viktig naturen är för vårt barndomsminne och att vårt minne påverkar hur vi ser på saker och ting senare i livet. Nordström skriver också att hon märkt genom en undersökning att barns uppfattning gentemot naturen skiljer sig åt från vilken kultur de har. Enligt hennes undersökning visar det sig att franska barn är mer inriktade på människorna runtomkring när de ska beskriva en miljö. Svenska barn är däremot mer inriktade på att förklara själva naturen runtomkring. Detta var något som kunde märkas i en del av frågorna i intervjuundersökningen som gjordes till denna uppsats. När respondenterna skulle beskriva utemiljöer var de flesta svar relaterade till naturen, det svar som skiljde sig åt var från personen med utländsk bakgrund. Denne var mer inriktad på att beskriva vikten av människorna runtomkring.

    Factors Influencing Tourism Destinations Attractiveness: The Case of Malaga2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Destination attractiveness is a subjective concept that has raised discussions among academics and researchers within the field of tourism. Attractiveness has been studied from different approaches, and due to the importance of tourism in contemporary societies, it has also been studied within different disciplines of knowledge, without achieving an agreement on its definition, measure and creation. This thesis is an attempt to contribute to these discussions through the analysis of the case of Malaga, Spain, a city with a long and strong relation to tourism, but which for particular reasons and context, had to develop its tourism sector almost from the scratch over the course of recent decades, before becoming one of the most important urban cultural destinations in Spain.

    This thesis will explore the factors that influenced the creation of Malaga’s attractiveness and the strategies that supported this evolution.

    Embedding socio-ecological sustainability into impact investor due diligence.2011Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Impact investors, seeking financial returns from investments that actively create social or environmental value, use a process known as due diligence to vet incoming investment opportunities. Some industry-wide tools have come to aid investors in this task. Existing metrics are not sufficient to assess the environmental performance of investee companies, the result of which is an allocation of increasing investment dollars into ventures and industries that are not operating within the limits of the socio-ecological systems upon which society depends. This paper proposes the creation of an investor toolkit that would allow users to effectively integrate the principles of strategic sustainable development (SSD) into the due diligence process. Such a toolkit would explain how current due diligence support tools could be used to construct comprehensive sustainability analyses of potential investments. The proposed toolkit was conceived after interviews with impact investors, social entrepreneurs, and industry experts. The research findings confirm a need for investors to use a strategic understanding of sustainability during the due diligence process, in order to increase portfolio value over time.

    Android: Resource Consumption in Native and Web Applications2013Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [en]

    There is an ongoing debate by people in the industry whether to make native or web applications. These discussions mostly surround issues about development costs, user experience and capabilities. Another aspect of this debate is the fact that mobile devices have varying hardware specifications which is another factor to consider when making this decision. What we want to shed some light on is how performance is affected on the device when using these two different approaches of application development. The use of CPU/RAM and Energy is our primary concern and in our experiment we measure these values on two similar applications where one uses Nested Layouts and the other a WebView. The experiment was made on three different devices with varying specifications. What we found was that Web applications have a bigger impact on overall performance and because of this use more battery. While the debate certainly won't come to a close with results they are conclusive when it comes to the topic of performance and will be of value to developers who are concerned about it.

    Video Games and Software Engineers: Designing a study based on the benefits from Video Games and how they can improve Software Engineers2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Context: This is a study about investigating if playing video games can improve any skills and characteristics in a software engineer. Due to lack of resources and time, this study will focus on designing a study that others may use to measure the results and if video games actually can improve software engineers.

    Objectives: The main objectives are finding the benefits of playing video games and how those benefits are discovered. Meaning what types of games and for how long someone needs to play in order to be affected and show improvements. Another objective is to find out what skills are requested and required in a software engineer. Then it is time to design the study based on the information gathered.

    Methods: There is a lot of literature studying involved. The method is parallel research which is when reading about the benefits of playing video games, then also reading and trying to find corresponding benefits in what is requested and required in software engineers.

    Results: There are many cognitive benefits from video games that are also beneficial in software engineers. There is no recorded limit to how long a study can go on playing video games that it proves to have negative consequences. That means that the study designed from the information gathered is very customizable and there are many results that can be measured.

    Conclusions: There is a very high chance that playing video games can result in better software engineers because the benefits that games provide are connected to skills requested and required by employers and other expert software engineers that have been in the business for a long time and have a high responsibilities over other teams of software engineers.

    Cultivating the Social Field: Strategically moving Urban Agricultural Projects towards Sustainability2012Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    The urban landscape requires a shift to a more self-sufficient, healthy and sustainable future. Urban agricultural (UA) projects are one way to do so. This research explores how low-income UA projects in North America and Europe can be supported strategically in moving towards a sustainable future. The authors analysed UA projects using the 5 Level Framework (5LF) and the Framework for Strategic Sustainable Development (FSSD) to understand their current reality and to help determine sustainable advances within UA projects. Leverage Points were also used as a subsidiary analytical tool to help pinpoint effective actions of change. Research resulted in the creation of Strategic Recommendations and guidance for UA projects to help foster a societal shift towards sustainability.

    Humor i omvårdnaden: En litteraturstudie2012Student thesis
    Abstract [sv]

    Bakgrund: Humor kan ofta fungera lika bra och ibland till och med bättre än medicinering och kan även ge patienten ett bättre välbefinnande och en möjlighet till att minska på känslor som ångest, ovänlighet eller frustration. En sjuksköterska som är glad och positiv kan ofta göra ett bättre arbete och på så vis ge patienten en bättre omvårdnad. Syfte: Syftet med studien var att belysa hur omvårdnadsarbetet kan påverkas av humor mellan patienter och/eller vårdtagare och sjuksköterskor. Metod: En litteraturstudie baserad på nio artiklar som redovisade studier med en kvalitativ design och som analyserades med hjälp av en innehållsanalys. Resultat: Analysen resulterade i tre kategorier; humor som en kommunikationsstrategi, humorn som en förhållningsstrategi och humor som en omvårdnadsstrategi. Ur kategorierna framkom att humorn var en viktig del i omvårdnaden med patienterna och sjuksköterskorna använde sig av humorn som en strategi i omvårdnadsarbetet. Sjuksköterskan ansåg även att grundandet av relationer mellan dem och patienterna skapade betydelsefulla band. Då sjuksköterskan ansåg sig ha gjort ett bra jobb var då hon/han lyckats locka fram ett leende eller helt enkelt ett skratt hos patienten. Slutsats: Humor kan vara en positiv kraft och fungera som en kreativ strategi både i omvårdnadsarbetet och för kommunikationen men också för att kunna hantera svåra situationer i omvårdnaden och i arbetsmiljön.

    Purposeful Action: organizational practices that contribute to a culture of strategic decision making for sustainability2012Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Current methods for reaching and defining success in society are not sustainable. A major shift in society’s definition of economic success is required, and organizations represent a key leverage point in the transition to a sustainable economy. This research looks to practices within organizations with a sustainability purpose in an attempt to understand how their organizational culture creates an environment for continual strategic decision making towards sustainability. A combination of literature review and structured interviews were used to elicit the cultural practices of 18 organizations with a clear social and ecological sustainability purpose. The research confirmed the importance of organizational culture for maintaining alignment with a sustainability purpose by fostering motivation and commitment towards sustainability at both a collective and individual level in the organization. Eight overarching areas of practice were identified as being present in the organizations included in the study. The practices identified help organizations to act strategically and in the right direction towards sustainability on a daily basis, standing as a complement to the strategic prioritization model of the FSSD.

    Design of Modified UCHT Sequences2006Conference paper (Refereed)
    Abstract [en]

    In this paper, we consider the design of a class of unified complex Hadamard transform (UCHT) sequences. An effi- cient modification is imposed to those sequences to better suit applications in asynchronous code-division multiple- access (CDMA) systems. These modified UCHT sequences preserve the orthogonality of the original UCHT sequences and offer increased design options due to an increased number of parameters. The design of UCHT, modified UCHT, and Oppermann sequences is then formulated with reference to optimizing the maximum nontrivial aperiodic correlation value. These optimization problems can then be solved efficiently using a genetic algorithm with the maximum nontrivial aperiodic correlation value serving in the definition of a fitness function. Numerical examples illustrate the benefits of modified UCHT sequences over the original UCHT sequences.

    Design of Sequence Family Subsets Using a Branch and Bound Technique2009In: IEEE Transactions on Information Theory, ISSN 0018-9448, E-ISSN 1557-9654, Vol. 55, no 8, p. 3847-3857Article in journal (Refereed)
    Abstract [en]

    The number of spreading sequences required for Direct Sequence Code Division Multiple Access (DS-CDMA) systems depends on the number of simultaneous users in the system. Often a sequence family provides more sequences than are required; in many cases the selection of the employed sequences is a computationally intensive task. This selection is a key consideration, as the properties of the sequences assigned affect the error performance in the system. In this paper, a branch and bound algorithm is presented to perform this selection based on two different cost functions. Numerical results are presented to demonstrate the improved performance of this algorithm over previous work.

    Abstract [en]

    The number of spreading sequences required for Direct Sequence Code Division Multiple Access (DS-CDMA) systems depends on the number of simultaneous users on the channel. The correlation properties of the sequences used affect the bit error rate of the system. Often a sequence family provides more sequences than are required and in many cases the selection of the employed sequences is a computationally intensive task. In this paper, a branch and bound algorithm is presented to optimise the subset of available sequences given the required subset size. In contrast to previous approaches, the resulting subset is guaranteed to be optimal. Numerical results are presented to demonstrate the improved performance of this algorithm over previous work.

    Bit Error Rates of Large Area Synchronous Systems2008Conference paper (Refereed)
    Abstract [en]

    Large Area Synchronous (LAS) sequences are a class of ternary interference free window spreading sequences. One of their advantages is the ability to construct permutation LAS families in order to reduce adjacent cell interference (ACI) in cellular systems. There has been little previous numerical work to examine the effect of using permutation families compared to simply reusing the same LAS family across different cells. The bit error rates resulting from two cell systems employing both permutation families and sequence reuse are considered here by simulation.

    Combination Oppermann Sequences for Spread Spectrum Systems2005Conference paper (Refereed)
    Abstract [en]

    Numerous spread spectrum applications require families of long spreading sequences, often used at very high chip rates. In this paper, an algebraically simple way of generating long sequences by combining shorter polyphase sequences is presented, aimed at asynchronous spread spectrum systems. The approach is motivated by the fact that polyphase sequences offer increased design options, in terms of the supported range of correlation characteristics, while combination sequences allow for simpler generation of long sequences. It leads to the definition of combination Oppermann sequences, the properties of which are investigated in this paper. Numerical results indicate that the families of these proposed combination sequences provide favourable aperiodic correlations. The presented family of combination Oppermann sequences is therefore suitable for applications that rely on rapid synchronisation and are required to provide multiple access to the system.

    On the Classification of Large Area Sequences2007Conference paper (Refereed)
    Abstract [en]

    Large Area (LA) sequences form a class of ternary spreading sequences which exhibit an interference free window. In addition, these sequences have low correlation properties outside this window. Work to date has concentrated on examining the parameters and performance of LA sequences with reference to only a small number of example families. In this paper we develop general conditions which an LA family must satisfy. The development of these conditions allows for the production of computationally efficient tests to determine whether a given family is an LA family. In particular, these tests can form the basis for algorithms to construct LA families, allowing for a larger number of families with the potential for higher energy efficiency than those of previous work.

The properties of these sequences are presented, and indicate that periodic Oppermann sequences are suitable for combination to generate families of longer sequences. Numerical examples show that periodic Oppermann sequences can be designed for ranging or synchronisation applications or for supporting multiple access spread spectrum communication systems.

    Integrating Participatory Processes in Planning for Strategic Sustainable Development2011Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    This thesis examines how dialogue-based methodologies can be integrated into a participatory planning process for strategic sustainable development. Evidence of the complex nature of the sustainability challenge is cited as necessitating tools and methodologies suited for dealing with complexity. The methodologies in this study were designed to use dialogue to address complex problems in which outcomes are unpredictable. Within the sustainability practitioner community, we identified a need for research on systematic guidance for pairing engagement processes with use of the Framework for Strategic Sustainable Development (FSSD). This research focuses on how a specific set of dialogue-based methodologies within the Art of Hosting network can be integrated with the FSSD to strengthen the linkage between content and process. As the culmination of our research, we have developed The Weave: Participatory Process Design Guide for Strategic Sustainable Development (www.theweave.info). It includes a Template for process design, suggestions and examples for use, and guiding principles. It is the first prototype of participatory process design guidance to be offered for pilot testing in the field of strategic sustainable development.

    Retention of IT Consultants: How to Grow Employee Loyalty – the case of T-company2008Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Most IT / Telecommunication consulting companies suffer high employee turnover. Engaged and satisfied employees are more likely to stay with their companies. Identifying motivation and satisfaction factors for IT consultants is therefore of great importance in increasing employee retention. The purpose of this research is to investigate what are the most important motivation and satisfaction factors for IT consultants, what causes consultants to stay and what are the main reasons for leaving their companies. Understanding IT consultants' motivation and needs could help IT consulting companies to lower turnover, and retain good employees by satisfying their needs as much as is reasonable.

    Kvinnor utsatta för partnerrelaterat våld: En kvalitativ litteraturstudie om dessa kvinnors upplevelser av bemötandet från hälso- och sjukvårdspersonal.2010Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Bakgrund: I Sverige förekom det 2008 över 20 000 anmälda fall där kvinnor blivit misshandlade. En omfattande studie utförd i Norge visade att över en fjärdedel av kvinnorna varit/är utsatta för partnerrelaterat våld. Kvinnor utsatta för partnerrelaterat våld söker ofta hjälp inom hälso- och sjukvården när de har blivit misshandlade. Hälso- och sjukvården har dock bristande rutiner att upptäcka kvinnomisshandel och vårdpersonalen saknar kunskap om hur kvinnor utsatta för partnerrelaterat våld skall bemötas. Syfte: Syftet med studien var att undersöka hur kvinnor utsatta för partnerrelaterat våld upplever bemötandet av hälso- och sjukvårdspersonal. Metod: Studien är utförd som en litteraturstudie med kvalitativ ansats och baseras på åtta vetenskapliga artiklar. Artiklarna analyseras enligt Graneheim och Lundmans analysmetod. Resultat: Hälso- och sjukvårdspersonals bemötande av kvinnor utsatta för partnerrelaterat våld varierade. Kvinnorna var sårbara, hade sänkt självförtroende och var rädda för konsekvenser om misshandeln skulle bli känd. Det kunde resultera i att kvinnorna inte berättade för vårdpersonal om partnerrelaterat våld. Att avslöja misshandeln upplevdes därför lättare när vårdpersonal frågade om misshandel samtidigt som en förstående och empatisk attityd uppvisades av vårdpersonal. Vårdpersonals tidsbrist, bristande intresse att hjälpa och okunskap om partnerrelaterat våld upplevde kvinnorna som faktorer av ett dåligt bemötande. Slutsats: Utbildning och riktlinjer för hälso- och sjukvårdspersonal gällande partnerrelaterat våld behövs i större omfattning. Då partnerrelaterat våld även innefattar faktorer av social och psykologisk karaktär behöver behandlingen ses utifrån ett bredare perspektiv, detta för att bättre kunna hjälpa kvinnor utsatta för partnerrelaterat våld.

    What are the affordances fostered by social media for amateurs artists?2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The research engages the use of social media sites for musicians with a focus on Facebook. It determines which are the advantages the platform makes available for musicians, allowing them to employ Do It Yourself strategies of production, audience relationship management and self-management. The importance of audience response and demographics allow any musician integrate keen insight into the content delivery and thus, optimize their management accordingly. This thesis will establish the affordances that engage what aspects and uses of Facebook are changing the way amateurs operate. The research appropriates the context of professionalism to the variable of knowledgeability, know-how, and Stebbins’ (1977) seven variables (confidence, perseverance, continuation commitment, preparedness and self-conception) in order to note a definition of the modern amateur in contrast to professionals.

    Design and Decision Making: Backcasting using principles to implement cradle-to-cradle2008Independent thesis Advanced level (degree of Master (One Year))Student thesis
    Abstract [en]

    Human society is currently designed based on linear patterns, without concern for and interactions with the biosphere. The natural world works in cycles, and in order to interact with these systems in a sustainable way, the redesign of human society according to the paradigm of cyclical thinking is required. This paper explores the synthesis and synergies between the cradle-to-cradle concept and a Framework for Strategic Sustainable Development in the context of sustainable development. The research tests whether Backcasting using Sustainability Principles is supportive to the implementation of the cradle-to-cradle concept and draws on relevant literature as well as interviews with experts. Based upon this research a process tool is designed and tested within a case study. Results indicate that, when backcasting using sustainability principles, principles for design and principles for decision-making provide synergistic characteristics in the process of implementation. Inspiring design principles, such as the ones suggested by the cradle-to-cradle concept, provide powerful engagement for a social learning process that works towards sustainable development. A structured decision-making process based on backcasting using sustainability principles provides the constraints and criteria for robust decision-making along the journey.

    Query Expansion Research and Application in Search Engine Based on Concepts Lattice2009Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [en]

    Formal concept analysis is increasingly applied to query expansion and data mining problems. In this paper I analyze and compare the current concept lattice construction algorithm, and choose iPred and Border algorithms to adapt for query expansion. After I adapt two concept lattice construction algorithms, I apply these four algorithms on one query expansion prototype system. The calculation time for four algorithms are recorded and analyzed. The result of adapted algorithms is good. Moreover I find the efficiency of concept lattice construction is not consistent with complex analysis result. In stead, it is high depend on the structure of data set, which is data source of concept lattice.

    Esoko and WhatsApp Communication in Ghana: Mobile Services such as Esoko and WhatsApp in Reshaping Interpersonal Digital Media Communication in Ghana2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The predominant use of mobile media such as SMS and MIM across various sectors in Ghana is incontrovertibly influencing and reshaping interpersonal communications. This paper looked at the use of the Esoko SMS and WhatsApp MIM platforms and how the use of these two dominant platforms are enhancing and reshaping digital communication in the rural and urban Ghana respectively, as barriers of socioeconomic factors limits the use of sophisticated technologies in the rural setting. This is done by employing Madianou and Miller's notion of polymedia” to draw on the moral, social and the emotional use of mobile media in enacting interpersonal relationships and communications whilst keeping in focus the recursive repercussions.

    Shaping and Authorising a Public Health Profession.2014In: The South Eastern European Journal of Public Health, ISSN 2197-5248, Vol. 31 MayArticle in journal (Refereed)
    Abstract [en]

    The aim of this short communication is to stimulate a discussion on the state of a public health profession in Europe and actions which need to be taken to authorise public health professionals based on their competencies. While regulated professions such as medical doctors, nurses, lawyers, and architects can enjoy the benefits of the 2005/ 36/EC Directive amended by 2013/55/EU Directive on the recognition of professional qualifications, public health professionals are left out from these elite. Firstly, we use the profession traits theory as a framework in arguing whether public health can be a legitimate profession in itself, second, we explain who public health professionals are and what usually is required for shaping the public health profession, and thirdly, we attempt to sketch the road to the authorisation or licencing of public health professionals. Finally, we will propose some recommendation.

    Regional disparities in Hungary2015Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In the past decades, exacerbating regional disparities in the European Union as well as the newly joined Eastern European states have led to a growing interest in examining the spatial embeddedness of development. Hungary, a small and very monocentric country, has experienced rapid growth in the region of its capital city and its surrounding, whereas formerly lagging regions continued to fall behind. This thesis examines growing regional disparities in Hungary in order to provide a more comprehensive overview of the phenomenon and synthesise a growing body of both Hungarian and international literature based on their relevance for Hungary.

    As regional disparities rarely form an explicit research subject, the first aim of this thesis was to establish a suitable method for a comprehensive national level analysis. Within a mixed methodological framework, three theoretical perspectives on regional development were selected to analyse and reveal structural disparities, which were set in contrast with GDP levels of regions. On the one hand, the method proved to be useful to establish a refined rank order of the regions based on their approximated level and speed of development. On the other hand, the three different perspectives revealed structural strength and weaknesses underlying general development level of regions. The results did confirm the multiple advantages of the most developed regions, as well as the complex disadvantage of the most backward regions. Based on this experience a further increase in disparity levels can be expected in Hungary. Regions between the two extremes showed more heterogeneous outcomes across the perspectives, revealing very different development path and structural problems behind the performance level of these regions. Taken together, these findings support the heightening need of decentralization in Hungary, in order to tackle growing regional disparities and establish policy responses at a regional level.

    Decoding algorithms of Reed-Solomon code2011Independent thesis Advanced level (degree of Master (Two Years))Student thesis
    Abstract [en]

    Reed-Solomon code is nowadays broadly used in many fields of data transmission. Using of error correction codes is divided into two main operations: information coding before sending information into communication channel and decoding received information at the other side. There are vast of decoding algorithms of Reed-Solomon codes, which have specific features. There is needed knowledge of features of algorithms to choose correct algorithm which satisfies requirements of system. There are evaluated cyclic decoding algorithm, Peterson-Gorenstein-Zierler algorithm, Berlekamp-Massey algorithm, Sugiyama algorithm with erasures and without erasures and Guruswami-Sudan algorithm. There was done implementation of algorithms in software and in hardware. Simulation of implemented algorithms was performed. Algorithms were evaluated and there were proposed methods to improve their work.
