    Vilka erfarenheter har lärare av att undervisa elever med ADHD?2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med detta examensarbete är att ta reda på vilka erfarenheter lärare har av att arbeta med elever med ADHD i sina klasser. Studien riktar sig till grundskolans tidigare år skolår 1-3. Det empiriska materialet har samlats in genom en bandad fokusgruppintervju där åtta verksamma grundskollärare med erfarenheter av att jobba med dessa barn medverkar. Lärarnas beskrivningar av sina erfarenheter kretsar till stor del kring de avvikande beteenden ett barn med ADHD kan ha i form av aggressiva utbrott och impulsiva handlingar. Hur dessa beteenden påverkar såväl eleven själv som läraren i klassen men även övriga kamrater.  Lärarna beskriver också vilka strategier de använder sig av för att minimera aggressiva utbrott samt vilka erfarenheter de har av inkludering och exkludering.

    Jag är en kille, fast jag har tjejkläder: En kvalitativ studie om barns konstruktion av kön i förskolan2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med föreliggande studie är att undersöka hur barn konstruerar kön i den fria leken på förskolan och om heteronormativitet påverkar denna konstruktion. Hur använder pojkar och flickor språket i relation till kön i fri lek? Hur kommer heteronormativitet till uttryck i barns fria lek? Föreliggande studie har utgångspunkt ur ett socialkonstruktionistiskt perspektiv. Vi använde oss av produktion av kvalitativa data genom videoobservationer på barn i förskolan, mellan åldrarna tre till sex år gamla. Resultatet visar att pojkar och flickor konstruerar sitt kön genom varierade könsladdade begrepp, språkliga repertoarer och handlingar. Manlig och kvinnlig heteronormativitet kom till uttryck genom dessa uttryck.

    Abstract [sv]

    Title: The perfect candidate – the selection process in a global organization.

    Authors: Kariin Adolfsson and Simon Leetsaar

    In today's society, it becomes increasingly current with correct person on correct place in the

    working life. What requires knowledge about how to recruit in a professional manner and

    reliable ways. In many bigger organizations, there is today a human resources department that

    only works with recruitment of new employees. The purpose with our research is to describe

    personnel selection process in a big swedish organization, how they work throughout the

    entire process. The study is based on three qualitative interviews and observations of two

    focus group interviews. The qualitative interviews were held with the personnel manager,

    deputy personnel manager and the recruiting manager. Moreover, a summary was formulated

    of the documents that the organization had given us access to. The results from the interviews

    and observations has then been analyzed compared to theoretical concepts chosen for the

    study. The analysis of the result shows that the organisation follows a surely prepared

    procedure in the personnel selection process that reflects the theoretical concepts chosen for

    the study. Finally, suggestions is presented how the organisation can work furthermore in

    order to improve their work with recruitment.

    Kambili and Tambudzai: Inspirational Young Women from Africa2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This essay explores the living conditions of the main characters Kambili in Purple Hibiscus by Chimamanda Ngozi Adichie and Tambudzai in Nervous Conditions by Tsitsi Dangarembga and their struggle to achieve personal freedom. It aims to show that colonial stereotypes are challenged through the girl´s struggles.

    It starts with a short exposé over post-colonial theory, here a methodological viewpoint, which is important to consider Kambili and Tambudzai from. It furthermore considers how their extensive family circumstances have impact on these two young protagonists, and finally examines how they employ formal and informal education as a tool to make changes in their lives and become inspirational young African women.

    Representativ demokrati: Hur väl fungerar den representativa demokratin och vilka är politikerrollen i Ängelholms Kommun?2000Student paper second termStudent thesis
    Abstract [sv]
    Idag har väljarna möjlighet, även vid de kommunala valen, att rösta, inte endast på ett parti, utan även på en enskild kandidat. Detta medför att en stor förändringsprocess har inletts både då det gäller politikerrollen och förutsättningarna för en fungerande demokrati. samtidigt har det under senare tid allt mer uppmärksammats att det, runt om i landet, råder stor frånvaro vid kommunalfullmäktigesammanträdena. De ledamöter som väljarna gett förtroendet att föra deras talan är alltså inte närvarande vid sammanträdena och i vissa fall ej heller deras ersättare. Detta har lett fram till följande frågeställningar: (i) Hur uppfattar fullmäktigeledamöterna sin roll som politiker? (ii) I vilken utsräckning deltar de ordinarie ledamöterna vid fullmäktigesammanträdena? (iii) Vad är det som påverkar i vilken utsträckning ledamöterna deltar vid sammanträdena? (iv) Vilken betydelse - ur ett demokratiskt perspektiv - har de ordinarie ledamöternas deltagande?

    Gender Control: A Feminist Approach to the Lyrics of Britney Spears and Backstreet Boys2001Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [en]
    Music is produced and consumed by adolescents in ways that both strengthen their sense of self, and serve to construct the social world in which their identities operate. It is hard to determine how much of the sex role imagery contained in popular music is perceived by young people. However, there is a close connection between the performers, here Spears and BSB, and the message of their lyrics. Spears’ lyrics give animplicit message of a glorification of beauty and material things while BSB’s lyrics give the latent message of the importence of a world filled with stars, parties and drugs. Both artists perform lyrics with conventional, contrastive and mixed gender roles.

    SimSpelGen: Ett grafiskt verktyg för konstruktion av radarscenarion2001Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]
    SimSpelGen is a graphical, platform independent tool generating radar scenarios. SimSpelGen was made for Ericsson Microwave Systems (EMW) in Mölndal, where an important system unit in the radar logic is the simulator. The simulator uses predefined static radar scenarios from which it extracts radar information. The scenarios are stored in files which contains information about the different objects, e.g. aircrafts, robots, sensors and clutters. EMW’s guidelines for projects, documenting and software engineering follows well known software development design patterns, which the thesis project was set to obey. Consequently the project was divided into four phases; requirements, design, implementation and test. Each phase has generated different documents such as an iteration plan, several requirement specifications, design specifications containing divers flow charts and class structural diagrams. The thesis project resulted in a well designed tool that met the requirements set by EMW except the ability to play the scenarios in real time.

    Business Intelligence - ett underlag för strategiskt beslutsfattande2009Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Beslut innebär att välja mellan olika alternativa handlingar för att uppnå de angivna målen. För att underlätta beslutsfattande finns det ett antal olika stödsystem som tar fram underlag till besluten. Vi är intresserade av att se hur dessa understödjer strategiskt beslutsfattande och till vilka typer av beslut som de används.

    Uppsatsens syfte är att granska beslutsstöds betydelse och hur beslutsstöd kan underlätta organisationens verksamhet och dess beslutsprocesser. Vi vill skapa en bakomliggande förståelse om beslutstöds användbarhet och huruvida beslutsstöd används, samt i vilken utsträckning. Vi vill även undersöka de nackdelar som skapas i och med användandet av beslutsstöd.

    Studien visar att användning av Business Intelligence effektiviserar beslutsprocessen och möjliggör för ett ökat proaktivt agerande. Samtidigt skapas ett beroende av Business Intelligence vid aktiv användning.

    Vibrationer och engesvängningar i Alfdex separator2019Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this thesis is to create a greater understanding of what happens inAlfdex’s separator in terms of natural frequencies, also called resonances. Try in asystematic way to find out where the problem is and produce a possible solutionto the problem. To achieve this smoothly, vibration measurements were made onthree different models with two variants, a total of six different variants. Themeasurements made with an electric shaker were set to run a sweep of 2-500Hz,which means that it increases the frequency from 20-500Hz with a constantacceleration of 2G. The measurement was first made on these six variants and, onthe basis of the results, it has been possible to compare with the modificationsmade.As the first modification, the disks in the separator were glued together to see ifthey made any difference from the previous result. As the next test spacers wereprinted out of the 3D-printer, that would replace the existing springs in theseparator, to aww what happens if we do not have any springs. There was also atest where the top of the separator the so-called house, was cut into a larger holeso as to see how the disks hold a constant amplitude relative to each other, whichmeans that the disks are not exposed to any natural frequencies. The springs werefilmed to see how they act and move, where it is clear that there are naturalfrequencies in the springs.Based on these tests, it can be concluded that the disk in question are not aproblem. The problem instead has its foundation in the springs that carry the diskstack throughout the separator, resonances in these give a great influence in theentire contents of the separator.

    VERCOM: Verification of Communicationslink1998Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]
    We have built hardware that retrieves data 763 times/sec from a testbox. Data is transferred five nibbles at a time. The lower five nibbles come first, and are stored in latches until the higher five nibbles arrive. The five entire bytes are then delivered to the PC. The transmission uses handshake between the testbox and the databuffer, and between the databuffer and the PC respectively to achieve sunchronisation. Software is made and consists of three parts : VERCOME Sampling, VERCOM Analys and VERCOM Tempbox. VERCOM Sampling retrieves the data from the hareware and saves it to a file on the hard disk. VERCOM Analys allows for analysis of the sampled data at a speed that is 50 times lower than when data was sampled in real time. VERCOM Tempbox controls a temperature box. This to see how the hardware responds to wxtreme cold and warm temperatures.

    Guiding and guided tours2009Collection (editor) (Other academic)
    Abstract [en]

    This book is based on the collaborative work and experience from Swedish researchers in an new and promising field of scientific and management oriented inquiry: guided tours. The book represents a wide range of scientific perspectives such as organizational theory, human geography, architecture, ethnology and technology.

    The chapters are divided into three themes: Guided tours as a phenomenon, Guided tours and guidebooks and finally Guided tours: their production, content and use. And your guides - the authors - will provide various kinds of insights. We will follow the history of guidebooks and their followers, experience the smell of sage and find out how a guided tour at a construction site can be performed. Let's take a walk...

    Förberedande arbete inför certifiering av livsmedelssäkerhet på Lantmännen AXA Foodservice, Laholm2008Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    People have the right to expect the food they eat to be safe and suitable for consumption. Food handlers therefore have a responsibility to assure that food is safe and appropriate for eating. The aim of this project was to prepare the company, Lantmännen AXA Foodservice, in Laholm, Sweden, for certification of Food Safety by the BRC Global Standard.

    Flow charts for every line in the production of pancakes, meat products and wraps were made, 14 in total. A document of all the company’s raw material was made where the ingredients were divided into different categories.

    The HACCP-plan, including risk analysis and control chart, is developed and upgraded to the production of today. A total of 17 risk analysis and control charts have been made for all the lines in production. One risk analysis for the ingredients in the wraps production has also been made. A traceability test was performed where a product made earlier this year was chosen and all its ingredients were traced and lab tests controlled.

    The project has resulted in a good and applicable HACCP which meets the requirements of the BRC standard. The traceability test needs a few completions to fulfil the standard, but a very good beginning has been made.

    Klimatanalys av avloppsreningsverk: Analyser av två av Laholmsbuktens VA:s avloppsreningsverk med förslag på förbättringsåtgärder2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The intensified greenhouse effect is the biggest cause for a negative climate change. Global warming is a result of enhanced greenhouse effect and poses a potential threat for humans and its surrounding environment that can result in disastrous consequences. The rise in temperature is driven by increased human activity whereas the leading cause for emissions of greenhouse gases is the combustion of fossil fuels. The prominent source of emissions is from the following sectors: transport, industrial and energy. The task of reducing the emissions of greenhouse gases is both globally and internationally prioritized. Progress has been made although every potential source for emissions has to be investigated in order to reduce the total climate impact. Based on scientific research, wastewater treatment plants are also a contributing factor to the greenhouse effect by emissions of gases. This bachelor’s thesis is investigating two wastewater treatment plants and identifying which processes contribute to the climate impact. The climate impact is calculated with an Excel-based analyzing tool and the results show the Carbon Footprints for the treatment plants. The purpose of this paper is to present result acquired from the treatment plants and identify the processes that have the biggest impact on our climate. Afterwards, solutions derived from the analysis of results will be suggested to improve and bring additional help to the treatment plants with their climate work. In conclusion, it is determined that the treatment plants both have net emissions of greenhouse gases. The biggest contributor is the wastewater treatment and the use of biogas. Results from analysis show that some of the assumptions on emissions made in the tool make the initial results doubtful. Therefore, further research is needed on this subject in order to produce more reliable facts.

    Internet Provisioning in VANETs: Performance Modeling of Drive-Thru Scenarios2019In: The international journal of robotics research, ISSN 0278-3649, E-ISSN 1741-3176, Vol. 38, no 8, p. 910-934Article in journal (Refereed)
    Abstract [en]

    Drive-thru-Internet is a scenario in cooperative intelligent transportation systems (C-ITSs), where a road-side unit (RSU) provides multimedia services to vehicles that pass by. Performance of the drive-thru-Internet depends on various factors, including data traffic intensity, vehicle traffic density, and radio-link quality within the coverage area of the RSU, and must be evaluated at the stage of system design in order to fulfill the quality-of-service requirements of the customers in C-ITS. In this paper, we present an analytical framework that models downlink traffic in a drive-thru-Internet scenario by means of a multidimensional Markov process: the packet arrivals in the RSU buffer constitute Poisson processes and the transmission times are exponentially distributed. Taking into account the state space explosion problem associated with multidimensional Markov processes, we use iterative perturbation techniques to calculate the stationary distribution of the Markov chain. Our numerical results reveal that the proposed approach yields accurate estimates of various performance metrics, such as the mean queue content and the mean packet delay for a wide range of workloads. © 2019 IEEE.

    We report on a tool prototype for model-based testing of cyber-physical systems. Our starting point is a hybrid-system model specified in a domain-specific language called Acumen. Our prototype tool is implemented in Matlab and covers three stages of model-based testing, namely, test-case generation, test-case execution, and conformance analysis. We have applied our implementation to a number of typical examples of cyber-physical systems in order to analyze its applicability. In this paper, we report on the result of applying the prototype tool on a DC-DC boost converter. © Springer International Publishing Switzerland 2015

    Model-Based Testing of Cyber-Physical Systems2016In: Cyber-Physical Systems: Foundations, Principles and Applications / [ed] H. Song, D.B. Rawat, S. Jeschke, and Ch. Brecher, Saint Louis: Elsevier, 2016, p. 287-304Chapter in book (Refereed)
    Abstract [en]

    Cyber-physical systems (CPSs) are the result of the integration of connected computer systems with the physical world. They feature complex interactions that go beyond traditional communication schemes and protocols in computer systems. One distinguished feature of such complex interactions is the tight coupling between discrete and continuous interactions, captured by hybrid system models.

    Due to the complexity of CPSs, providing rigorous and model-based analysis methods and tools for verifying correctness of such systems is of the utmost importance. Model-based testing (MBT) is one such verification technique that can be used for checking the conformance of an implementation of a system to its specification (model).

    In this chapter, we first review the main concepts and techniques in MBT. Subsequently, we review the most common modeling formalisms for CPSs, with focus on hybrid system models. Subsequently, we provide a brief overview of conformance relations and conformance testing techniques for CPSs. © 2017 Elsevier Inc. All rights reserved.

    Revisorer i Sverige och Danmark - En studie kring svenska respektive danska revisorers syn på IAS 36, IAS 38 och IFRS 32008Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Sedan 2005 måste alla börsnoterade företag samt de företag som upprättar en koncernredovisning tillämpa IFRS regelverk. Bakgrunden tar upp revisorers åsikter kring införandet av IFRS samt varför man valde att införa IFRS regelsystem. Bakgrunden har därför naturligt lett oss in på uppsatsens problemformulering ”Hur ser svenska respektive danska revisorer på problematiken kring de internationella redovisningsstandarderna, IFRS, angående immateriella tillgångar?” Syftet med uppsatsen är att ta reda på ifall IFRS har medfört en harmonisering mellan länders olika redovisningar. Vi har valt att titta på standarderna IAS 36, IAS 38 samt IFRS 3 som reglerar immateriella tillgångar. Under uppsatsens gång har två revisorer intervjuats som berättar med egna ord vad transformeringen har inneburit samt vilka konsekvenser IFRS har medfört. Införandet har varit delvis negativt för de mindre företagen då de oftast inte har den kompetens som IFRS kräver. Det har även blivit dyrare för revisionsbyråerna sedan implementeringen. Den svenska revisorn anser att det är svårt att uppnå en harmonisering då IFRS kräver mycket egna tolkningar och antaganden. Den danska revisorn menar på att redovisningarna har blivit mer likartade sedan införandet av IFRS men att de fortfarande är en aning nationellt präglade. Intervjuerna och den teori vi har använt ledde fram till slutsatsen att full harmonisering inte har uppkommit ännu och att IFRS redovisningsstandarder angående immateriella tillgångar är svårtolkade. De revisorer vi intervjuat poängterar att man måste vara väl insatt i IFRS för att kunna göra dessa antaganden och tolkningar på ett korrekt vis.

    The effect of Norflurazon on photosynthetic activity in isolated thylakoids from wheat (Triticum aestivum L: )2006Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [en]

    This investigation has been performed on Norflurazon (NF) treated young wheat plants with

    emphasis on their capacity to perform light-driven photosynthesis, as an effect of carotenoid

    deficiency. The wheat seeds were soaked for approximately 17 hour in tap water or in water containing NF (28mg l-1 ca 10-4 M). Seedlings were grown for 7 days in a greenhouse (50 μmol m-2 s-1) or in weak light (ca 0.1 μmol m-2 s-1) in order to avoid photodestruction, before chloroplast and thylakoid isolation. NF-treatment and the low light condition also affected chlorophyll content. Isolated chloroplasts from NF-grown plants contained approximately 55 and 16 % of the chlorophyll content as compared to untreated plants grown in weak light or in greenhouse light, respectively.

    In addition, protein separation by polyacryl amide electrophoresis (SDS-PAGE) on isolated thylakoids showed that the apoproteins of the LHC II (i.e. LHCP) were undetectable after NF-treatment. Despite a large number of attempts to measure PS II activity in isolated thylakoids, this was proven to give unreliable data and these were therefore excluded from this report.

    The photosynthetic assays were therefore focused on PS I activity, which were compared between plants grown in greenhouse (untreated) or in weak light, with or without NF. As expected, PSI activity is greatly affected by light intensity, during growth as well as during the photosynhtetic assays. In untreated wheat, grown in the greenhouse, the highest activity was found at the strongest light intensity used at distance of 0.25 m from the light source (corresponding to approximately 1440µmol m-2s-1). The PS I activity then declines with decreasing intensity. A similar, albeit not so clear (lower maximum activity at strong light intensities), trend is observed in untreated wheat grown in weak light.

    Thylakoids isolated from NF-treated plants show a clear photoinhibition at strong light but a clear increase in activity at subsequently lower light intensities.

    Reliable Real-Time Communication for Future ITS (Intelligent Transport Systems) using HWA (Heterogeneous Wireless Access)2011Independent thesis Advanced level (degree of Master (Two Years)), 30 credits / 45 HE creditsStudent thesis
    Abstract [en]

    In this research oriented master’s thesis we have proposed a future vision of ITS (Intelligent Transport Systems) by utilizing the novel concept of HWA (Heterogeneous Wireless Access). Our proposal is backed by the investigation of the results of experiments conducted at CERES (Centre for Research on Embedded Systems), Halmstad University, Sweden to evaluate the quality of communication for V2V and V2I by using the IEEE 802.11p standard. We have also identified the expected scenarios with need of any other communication technology in replacement of IEEE 802.11p for V2V and V2I communication. We have also investigated the relevant research projects, experiments and their results on the basis of predefined constraints. In the investigated research projects the concept of HWA has been correlated with our proposal of HWA for ITS. We have identified that for smooth integration of any communication technology with IEEE 802.11p, an efficient and smart vertical handover protocol or method will be required. We have presented a blue print of a custom designed vertical handover technique which can be implemented for future ITS with further enhancements and experimental evaluations. We have also evaluated the worst case scenarios to assess the suitability of the HWA for the ITS. We proposed few solutions based on the evaluation of communication scenarios for the integration of IEEE 802.11p with other wireless communication technologies. Finally we have provided some conclusions and suggested future researches which must be conducted to realize the dream of ITS with support of HWA.

    Egyptian women's attitudes and beliefs about female genital cutting and its association with childhood maltreatment2007In: Nursing and Health Sciences, ISSN 1441-0745, E-ISSN 1442-2018, Vol. 9, no 4, p. 270-276Article in journal (Refereed)
    Abstract [en]

    This study aimed to establish Egyptian women's attitudes and beliefs about female genital cutting (FGC) or mutilation by applying a questionnaire module about violence to a subsample of 5249 married women from a total of 19 474 women who participated in the 2005 Egypt Demographic Health Survey. Women were interviewed to determine if they had been exposed to marital violence in the year prior to the survey, their attitudes and beliefs about FGC, and if they physically abused their children. The association of beliefs about FGC with maternal physical abuse was examined, adjusting for exposure to marital violence and other socio-demographic variables. Of the women surveyed 16.4% and 3.4% had been exposed to physical and sexual violence, respectively, during the year prior to the survey. Around 76% of the women surveyed intended to continue the FGC practice, and 69.8% had slapped or hit their children during the year prior to the survey. Holding positive beliefs about the practice of FGC or intending to continue it was associated with maternal physical abuse and this has significant implications for health and welfare workers in Egypt and for society in general.

    Idioms in English as a Second Language: Contextualization of L2 idioms (written context versus still pictures) and its effect on students' retention2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The main aim of the present study is to investigate whether there is a difference in retentionbetween two groups of Swedish second language learners of English when they are faced withidioms in a written context or in the form of still pictures. The subjects of the investigation aretwo different groups at a high school in Sweden. Both Group 1 and 2 consist of 24 subjectseach. For this study, 15 idioms were randomly selected. To Group 1, the idioms werepresented in a written context and to Group 2 the idioms were presented in the form of stillpictures. The subjects were given a pre-test and two post-tests to measure their retention.Moreover, the subjects were given a questionnaire in order to learn more about theirperception of idioms. I believe that, on the immediate post-test, Group 1 (the “written contextgroup”) did better than Group 2 (the “still pictures group”). Nevertheless, on the delayed posttest(testing long-term retention), Group 2 remembered more idioms than Group 1. But, it isimportant to note that contextualization of L2 idioms using written context and/or using stillpictures resulted, in general, to be effective strategies for the retention of idioms.

    Motåtgärder vid IT-forensisk liveanalys2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Live Analysis is a concept that in this paper means analyzing a computer system while it is running. This can be done for several reasons, such as when there is a risk that the system has encryption which can be activated when the system shuts down. Otherwise, it is common if you want to examine network connections, active processes or other phenomena that can be volatile, i.e. disappear when the system shuts down. This work will focus on countermeasures to live forensic analysis and describe different methods and strategies that can be used for these countermeasures. For example, we wrote a program that automatically shuts down the system when you insert a USB memory stick or any other media. These are usually the media which you have your forensic programs on when you do a live analysis. Other important elements of the work are the use of encryption, timestamps and malicious code for challenging live analysis. Our analysis of the topic shows that it is relatively easy to prevent that a live analysis can be performed in a reliable way.

    Optical Flow Features for Event Detection2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In this thesis, we employ optical flow features for the detection of the rigid or non‐rigid single object on an input video. For optical flow estimation, we use the Point Line [PL] method [2] (as a local method) to estimate the motion of the image sequence which is generated from the input video stream. Although the Lukas and Kanade [LK] is a popular local method for estimation of the optical flow, it is weak in dealing with the linear symmetric images even by use of regularization [e.g. Tikhonov]. The PL method is more powerful than the LK method and can properly separate both line flow and point flow. For dealing with rapidly changing data in some part of an image (high motion problem), a gaussian pyramid with five levels (different image resolutions) is employed. In this way, the pyramid height (Level) must be chosen properly according to the maximum optical flow that we expect in each section of the image without iteration. After determining the best‐estimated optical flow vector for every pixel, the algorithm should detect an object on video with its direction to the right or left. By using techniques such as segmentation and averaging the magnitude of flow vectors the program can detect and distinguish rigid objects (e.g. a car) and non‐rigid objects (e.g. a human). Finally the algorithm makes a new video output that includes detected object with flow vectors, the pyramid levels map which has been used for optical flow estimation and a respective binary image.

    Musikens påverkan på individer med autismspektrumdiagnos: En litteraturöversikt2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Individuals with autism spectrum disorder (ASD) tend to have a limited capacity for social interactions, communications, and usually show hyper or hypo reactions to sensory stimuli. Time spent in health facilities can therefore be extra stressful. Since music is used for therapy or pain relief in cancer treatment and dementia care for example, it would be interesting to further explore the effects of music. The aim of this literature review was to investigate how individuals with ASD are affected by music. Eleven literature articles were analyzed and as a result, four themes emerged: physical, social, emotional influence and also focus and coping. Anxiety, mood, and social interactions were affected in a positive way by music or music therapy. Physical reactions in the brain were seen in regions underlying music perception and emotional processing. The nurse’s goal is person-centered care, and the knowledge of the effects of music and the possibility to use music in clinical practice, could make working with ASD patients easier. Future research on this subject could provide further knowledge and result in guidelines and routines for an easy use of music in the care of individuals with ASD.

    Ett sista hopp: Obotligt sjuka patienters uppfattningar om dödshjälp2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den moderna sjukvårdens avancerade resurser räddar många liv, men kan också leda till ett utdraget och plågsamt döende. I ett fåtal länder i världen är eutanasi och läkarassisterat självmord ett val för den som drabbats av en obotlig sjukdom som leder till döden. Syftet med denna studie är att beskriva obotligt sjuka patienters uppfattningar om dödshjälp. En litteraturstudie genomfördes och relevanta sökord som motsvarade syftet användes vid artikelsökning. Vid bearbetning av data framkom tre olika kategorier med subkategorier som motsvarade de olika uppfattningarna. Resultatet visar att positiva uppfattningar till dödshjälp kan bero på patientens egna syn på värdighet, självbestämmande och hopp, medan negativa uppfattningar till dödshjälp kan bero på rädsla eller religion. Även kommunikation med vårdpersonal kan påverka patienters uppfattningar om dödshjälp. För att möta obotlig sjuka patienters behov den sista tiden i livet behövs det kunskap om alla sorters tankar patienten kan ha, detta gäller även tankar om dödshjälp. Vidare forskning inom området dödshjälp behövs för att möta alla utmaningar som det innebär när patienter önskar hjälp med att dö.

    Attityder till matematik.: Högskolestudenter berättar om sin inställning till matematik under gymnasietiden och om den har förändrats.2005Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]
    Syftet med vårt examensarbete var att undersöka vilka attityder till matematik högskolestudenter hade under sin tid på ungdomsgymnasiet, vilka faktorer som påverkade dessa attityder och hur de ser på matematik idag. Vi ville också ta reda på hur vi som blivande lärare kan bemöta elever med en negativ inställning till matematik. Detta undersökte vi genom att intervjua fyra studenter på en högskola i västra Sverige. Resultatet visade att tre av fyra intervjupersoner hade en positiv inställning till matematik och en hade en neutral inställning till matematik både under tiden på högskolan och på ungdomsgymnasiet. Tre av fyra studenter insåg nyttan av att studera och kunna matematik först på högskolan. Resultatet visade också att faktorer som motivation, intresse och skolmiljö (lärare, inlärningsstilar och kurslitteratur) till viss del påverkade deras attityd till matematik men att de först på högskolan fick möjlighet att reflektera över faktorerna. Självkänsla/självförtroende, möjligheter att påverka sin utbildning samt föräldrar ansåg studenterna inte hade en större betydelse för deras inställning till matematik. Sammanfattningsvis kan vi konstatera att skolan bör uppmana elever till att reflektera över sin egen skolgång för att de ska kunna förstå nyttan av kunskap, vilket kan bidra till en positiv inställning till olika skolämnen, speciellt matematik.

    Jeansproducenter använder sig av starka varumärken, vars attribut är till för att ge kundvärde. Syftet med denna uppsats är att ta reda på vilken betydelse varumärket, och dessa attribut, har vid köp av jeans. En ytterligare ansats är att urskilja olika marknadsföringsstrategier och hur de påverkar konsumenten. Detta görs genom en enkätundersökning som inriktas mot studenter på Högskolan i Halmstad. Resultatet visar att 71% av respondenterna är märkeslojala och att Lee, Levi´s, Diesel och Crocker är ohotat störst på marknaden. Att attributen är oerhört viktiga kan också utläsas av resultatet. Speciellt kvalitet, passform och bra storlekar värderas högt. Resultatet visar också att marknadsföringsstrategierna blir allt mer komplexa för att företagen ska kunna kommunicera de attribut dess varumärke står för.

    Abstract [sv]

    ABSTRACT

    Title: First steps towards successful recruitment – A study about a small Swedish firm’s recruitment strategy

    Course: Bachelor Dissertation - Leadership

    Authors: Filip Agby, Damir Macanovic and Thomas Mennerdahl

    Advisor: Anders Billström

    Key Words: Recruitment in small firms, recruitment strategy, wrong fit recruitment, HRM, right staff

    Problem enunciation: What pros and cons could the choice of recruitment strategy mean for a small Swedish firm.

    Purpose: The purpose of this thesis is to give recruiters a better understanding of how a small Swedish company could use different recruitment strategies, together with systematic preparations, to affect the experienced recruitment result. Another purpose is to study if earlier mentioned international research about small firms’ recruitment strategies is applicable to a small Swedish firm.

    Theoretical framework: The section initiates by introducing the reader to the subject through describing Human resource management with a focus on recruitment. Then we point out the importance of systematic preparations prior to recruiting. Thereafter we present five common recruitment strategies. The chapter ends with reasoning about successful recruitment and wrong fit recruitment.

    Method: We have used a qualitative approach to gather profound data for the study.

    Empirical perspective: The empirical framework presents the fallout of the interviews we had with the studied company.

    Conclusion: Our study implies that earlier international research about the challenges in small firms’ recruitment is applicable to our studied firm. The study also demonstrates that our firm have had and has a lack of resources, structure and discipline which is pointed out by the researchers. Particularly the neglection of systematic preparations, which increases the risk of wrong fit recruitment. Our result also shows that the firm uses advertising, network recruitment, recruitment firms and recruiting through the own website. Network recruitment was earlier considered to be fitting when the staffing requirement was very high and speed was of importance. Recruitment firms were on the other hand considered to have many valueable advantages and tended to generate successful recruitments.

    Abstract [sv]

    How can a multi project organisation use Wiki to support improvement of knowledge management and project evaluation to become a learning organisation? The main purpose of this thesis is to give management and employees a better understanding of how Wiki supports knowledge management and project evaluation. The second purpose is to illustrate possible difficulties and pit falls that comes with the implementation of Wiki based learning. The theoretical framework initiates by explaining multi project organizations, then describes Argyris and Schöns theories about organizational learning and learning organizations. The second half of the theory chapter brings up theories about important areas for a learning organization. We have used a qualitative approach to gather profound data for the study. The empirical framework presents the fallout of the interviews we had with the studied company. Our study demonstrates how Wikis can be a great support to improve knowledge management and project evaluation. A Wiki functions as a knowledge repository that integrates divisions in an organization and facilitates to take part of, document and share knowledge. The study also demonstrates that problems can occur when implementing a Wiki. This is shown by managerial resistance due to the attitude towards knowledge management and an uncertainty about quality control of a Wiki’s content. To answer this resistance the employees can suggest a demonstration where they during a period of time use Wiki to describe when it could have benefited them in the daily activities. To be follow up with a trialperiod if the outcome is successful.

    Reconfigurable Optical Interconnection Networks for High-Performance Embedded2005Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    In embedded computer and communication system the capacity demand for interconnection networks is increasing continuously in order to achieve high-performance systems. Recent breakthroughs show that by using reconfigurability inside a single chip substantial performance gains can be added. However, in this thesis the focus is on system level reconfigurability (between chips or modules) and the performance gains that potentially can be achieved by having support for runtime reconfigurability on the system level.This thesis addresses the field of runtime system level reconfigurability with the use of optics in switches and routers for data- and telecommunications, and in multi-processor systems used for embedded signal processing. Several reconfigurable systems for switching and routing with support to adapt for asymmetric traffic patterns are proposed and compared to identify how design choices affect flexibility, performance etc. The proposed solutions are characterized by their multistage optical interconnection networks with reconfigurable shuffle patterns, where the reconfigurability is provided by micro-optical-electrical mechanical systems. More specifically, application-specific bottlenecks can be resolved by reconfiguring the interconnection network according to the current application demands. The benefits of the architectural solutions are confirmed by simulations that clearly show that the architectures can achieve high performance for both symmetric application characteristics and for several classes of asymmetric application characteristics. The final architectural solution is characterized by electronic packet-switches interconnected through an optical backplane, which is reconfigurable. Moreover, the thesis presents how several signal processing applications can be mapped to run concurrently in a time-shared scheme on a single reconfigurable multi-processor system that has high flexibility to adapt for the application currently at hand. The interconnection network is then adapted (reconfigured) according to the demands of the currently executed application in each time instance. The analysis shows that it is feasible to build such a system with today’s components.

    Modular interconnection system for optical PCB and backplane communication2002In: Parallel and Distributed Processing Symposium., Proceedings International, IPDPS 2002, Abstracts and CD-ROM, Los Alamitos, Calif.: IEEE Press, 2002, p. 245-250Conference paper (Refereed)
    Abstract [en]

    This paper presents a way of building modular systems with a powerful optical interconnection network. Each module, placed on a Printed Circuit Board (PCB), has a generic optical communication interface with a simple electronic router. Together with optical switching using micro-electromechanical system (MEMS) technology, packet switching over reconfigurable topologies is possible. The interconnection system gives the possibility to integrate electronics with optics without changing existing PCB technology. Great interest from industry is therefore expected and the cost advantages are several: reuse of module designs, module upgrades without changing the PCB, low-cost conventional PCB technology, etc. In the version described in this paper, the interconnection system has 48 bidirectional optical channels for intra-PCB communication on each board. For inter-PCB communication, a backplane with 192 bidirectional optical channels supports communication between twelve PCBs. With 2.5 Gbit/s per optical channel in each direction, the aggregated intra-PCB bit rate is 120 Gbit/s full duplex (on each PCB) while the aggregated inter-PCB bit rate is 480 Gbit/s full duplex. A case study shows the feasibility of the interconnection system in a parallel processing system for radar signal processing.

    Optoelectronic router with a reconfigurable shuffle network based on micro-optoelectromechanical systems2004In: Journal of Optical Networking, ISSN 1536-5379, Vol. 4, no 1, p. 1-10Article in journal (Refereed)
    Abstract [en]

    An optoelectronic router with a shuffle exchange network is presented and enhanced by the addition of micro-optoelectromechanical systems (MOEMS) in the network to add the ability to reconfigure the shuffle network. The MOEMS described here are fully connected any-to-any crossbar switches. The added reconfigurability provides the opportunity to adapt the system to different common application characteristics. Two representative application models are described: The first has symmetric properties, and the second has asymmetric properties. The router system is simulated with the specified applications and an analysis of the results is carried out. By use of MOEMS in the optical network, and thus reconfigurability, greater than 50% increased throughput performance and decreased average packet delay are obtained for the given application. Network congestion is avoided throughout the system if reconfigurability is used.

    Reconfigurable optical interconnection system supporting concurrent application-specific parallel computing2005In: 17th Symposium on Computer Architecture and High Performance Computing: SBAC-PAD 2005 : proceedings : 24-27 October, 2005, Rio de Janeiro, PR, Brazil / [ed] Claudio L. Amorim, Washington, DC, USA: IEEE Computer Society, 2005, p. 44-51Conference paper (Refereed)
    Abstract [en]

    Application specific architectures are highly desirable in embedded parallel computing systems at the same time as designers strive for using one embedded parallel computing platform for several applications. If this can be achieved, the cost can be decreased in comparison to using several different embedded parallel computing systems. This paper presents a novel approach of running several high-performance applications concurrently on one single parallel computing system. By using a reconfigurable backplane interconnection system, the applications can be run efficiently with high network flexibility since the interconnect network can be adapted to fit the application that is being processed for the moment. More precisely, this paper investigates how the space time adaptive processing (STAP) radar algorithm and the stripmap synthetic aperture radar (SAR) algorithm can be mapped on a multi-cluster processing system with a reconfigurable optical interconnection system realized by a micro-optical-electrical mechanical system (MOEMS) crossbars. The paper describes the reconfigurable platform, the two algorithms and how they individually can be mapped on the targeted multiprocessor system. It is also described how these two applications can be mapped simultaneously on the optical reconfigurable platform. Implications and requirements on communication bandwidth and processor performance in different critical points of the two applications are presented. The results of the analysis show that an implementation is feasible with today's MOEMS technology, and that the two applications can be successfully run in a time-sharing scheme, both at the processing side and at the access for interconnection bandwidth.

    System-Level Runtime Reconfigurablity - Optical Interconnection Networks for Switching Applications2004In: Proceedings of the International Conference on Engineering of Reconfigurable Systems and Algorithms, ERSA'04 / [ed] Toomas P Plaks & M Gokhale, Athens, USA: CSREA Press, 2004, p. 155-162Conference paper (Refereed)
    Abstract [en]

    The performance requirements on data and telecommunication switches and routers are continuously increasing and it is evident that new ideas and architectures must come to light to satisfy these new demands. In this paper, a runtime reconfigurable modular design approach is presented, using state-of-the-art microoptical-electrical mechanical system (MOEMS) components. The paper introduces a novel field of reconfigurability, where reconfiguration is made on the system level instead of, e.g. fine-granularity reconfigurable logic. Different reconfigurable system solutions with support to adapt for asymmetric traffic patterns are proposed and compared to see how design choices affect flexibility, performance etc. The proposed solutions are characterized by their multistage networks with reconfigurable shuffle patterns.

    Visualizing the Potential of Reconfigurable Shuffle-Patterns in Optoelectronic Routers by the Use of MOEMS2004In: Proceedings of the IASTED International Conference Communication Systems and Networks / [ed] Salvador C.E.P., Calgary, Canada: ACTA Press, 2004, p. 148-154Conference paper (Refereed)
    Abstract [en]

    A reconfigurable high performance multistage router architecture is presented and simulated. The router backbone network is an optical shuffle exchange network that has the power of reconfigurability through the use of micro-optical-electrical mechanical systems (MOEMS). The router is subjected to different application classes. The application classes have different characteristics in terms of symmetric/asymmetric traffic properties. We compare our reconfigurable shuffle-pattern for all three application classes for the specified router architecture.

    Abstract [en]

    Health is a broad concept which can be viewed from different perspectives. Different parts can be included in the term such as disease, the absence of disease and well-being. Companies have

    different resources available to create benefitial conditions for individuals when it comes to their health. An example of a resource a company can use is a tax-free contributions in the form of a

    "healthcare subsidy" or "health allowance". The purpose of this study is to highlight the various conversations people have about healthcare subsidies in the workplace and our discussion is viewed partly from a sociocultural perspective. The authors did an inductive study. Seven interviews were conducted to collect empirical data. The discourses that emerged included the individual's own responsibility, the role of health care premium and that the talks were positive about health care.
