Analysis of Quality of Service of Wireless LAN for IEEE 802.11e
Nowadays Wireless LAN is playing a more and more important role in network systems. After 1999, in which the IEEE organization published its Wireless Local Network standard 802.11[1], many people saw the advantages of the standard but also the lack of support for multimedia streaming. A lot of research work has been done on the proposed IEEE 802.11e standard draft during the past 4 years. It is supposed to be able to fully support Quality of Service. The final version will be published early in 2004.
Matting of Natural Image Sequences using Bayesian Statistics
The problem of separating a non-rectangular foreground image from a background image is a classical problem in image processing and analysis, known as matting or keying. A common example is a film frame where an actor is extracted from the background to later be placed on a different background. Compositing of these objects against a new background is one of the most common operations in the creation of visual effects. When the original background is of non-constant color the matting becomes an under determined problem, for which a unique solution cannot be found. This thesis describes a framework for computing mattes from images with backgrounds of non-constant color, using Bayesian statistics.
Reducering av en komplex produktstruktur : - En studie av bränsletanksinstallationen på Scanias lastbilschassier
The product structure of the fuel tank installation is one of the most complex product areas at Scania. Caused by the number of parameters, which affect the fuel tank installation, a product structure is created which is very difficult to handle. Knowledge exist that the structure in a nearby future will be considerable more complex. The purpose of the study has been to understand in why this complexity exist and find ways to break the trend of a growing product structure. The goal was to achieve a more standardized fuel tank installation.A theoretical study was performed in order to bring knowledge in relevant areas both in general theory but also in documentation at Scania.
Förpackningshantering i det dolda : En studie om hur den interna hanteringen kan synliggöras och förbättras.
Handling materials and packaging, which is the focus of this study, requires efficient logistics, both internally and between companies. To achieve an efficient material flow, good information systems, whose role is to collect, store, process and distribute information, are required. The assumption that packagings are handled in an efficient manner is currently not a matter of course, when many companies do not prioritize the internal management of the package.The purpose of this report was to investigate how medium-sized businesses working with distribution and handling of spare parts packaging can improve their internal management of packaging. In order to answer the purpose, we have used an abductive process and a qualitative data collection. The study had Logistic Center Ljungby (LCL) at Electrolux Laundry Systems (ELS) as a case company and two other respondents, Nibe in Markaryd and Enertech in Ljungby.

Kreativ reklam attraherar och rekryterar
This paper supports the thesis that creative consumer advertising also can be used as a recruitment tool. By increasing the level of creativity used in their communication, a company can affect the attractiveness of themselves as future employers. The creative advertising influences the brands perceived creativity. It also increases the perceived social, development- and reputational value as well as the future intentions with the brand. By being more creative the brand is also viewed as making more marketing effort, which in turn affects the perceived potential of the brand in a positive way.
Webbaserade ERP-system - Ramverk för utvärdering
För att skapa en större konkurrenskraft och hantera det allt hårdare affärsklimatet väljer många företag idag att implementera Enterprise Resource Planning (ERP) system, dessa heltäckande affärssystem integrerar alla verksamhetens delar med en gemensam databas och skapar nya möjligheter. För att kunna utvärdera vilken nytta en organisation får av ett sådant system behövs det lämpliga analytiska ramverk. Trots att det finns ramverk för denna typ av utvärdering, råder brist på lämpliga utvärderingsverktyg. En ny utveckling på marknaden för dessa system är webbaserade ERP-system. Systemet köps istället som en tjänst, där systemet finns på en server hos tjänsteleverantören.
Rekryteringsstrategier inom marknadsföring och kommunikation : En kvalitativ studie avhur individer och organisationer hanterar sökandet efter medarbetare/arbetsgivare och hur rekryterare skapar matchning
This paper describes and analyzes how individuals and organizations that operate in careers in communications and marketing deal with the search for employees / employers, and how recruiting managers and recruitment consultants are working to create a match between the parties. The study was conducted on behalf of a recruitment agency that offers services in recruiting and staffing for organizations in communication and marketing. The empirical material consists of ten qualitative interviews from three different perspectives on the labor market, recruitment consultants, managers and employees. The interviews were analyzed from sociological and social psychological theories of organizations and individuals opportunities and strategies in today's western labor market. Conclusions that emerged are that organizations need for decreased amount of tied assets provides increased need for temporary employments.
Smarttelefon-sensorernas möjligheter - En studie om barometer-, GPS- och accelerometersensorer. The smartphone sensor possibilities - A case study featuring the barometer, GPS and accelerometer sensors
Denna rapport sammanfattar resultat av ett examensarbete på en högskoleingenjörsutbildning
som utfördes av två studenter på Malmö högskola.
Arbetets syfte var att genomföra en mängd olika experiment med accelerometer, barometer
och GPS i en modern smarttelefon. Ett antal scenarier för en tänkbar sensoranvändning i applikationer
formulerades för att vägleda olika experiment. Experimentdata dokumenterades noggrant
och analyserades med avsikten att skapa en databank med information för framtida studier.
Analys av data inkluderar höjdbestämning i naturen och i byggnader med hjälp av barometersensor,
geografisk position med hjälp av GPS, hastighet och acceleration under en hissfärd
med hjälp av accelerometer.
Rapporten innehåller en omfattande litteraturstudie om användning av sensorer vid inomhuspositionering.
Från analys av mätdata, kom vi fram till slutsatsen att är möjligt att beräkna höjden
från barometerdata med bra noggrannhet under optimala omständigheter. GPS höjden
från mätningarna har stor felmarginal jämfört med den verkliga höjden samt när den jämförs
med den beräknade höjden från barometern.
Genom att utföra en numerisk integration på accelerometer-data kom vi fram till att det är möjligt
att beräkna ungefär hur långt man har färdats med en hiss, dock att vissa detaljer måste tas
i beaktning..
Närhet och distans i Norrbottens läns landsting: Medarbetares upplevelse av sin arbetssituation
Begreppet employer branding handlar om en arbetsgivares attraktivitet utifrån olika faktorer så som lön, förmåner, utveckling, arbetsmiljö etc. Begreppet har under de senaste 10 åren utvecklat ett starkt fäste i organisationers strategiska prioriteringar.Norrbottens läns landsting står inför en av deras största utmaningar för att säkra den framtida kompetensförsörjningen. Landstinget står inför ett stort generationsskifte med många pensionsavgångar och måste lyckas attrahera nya medarbetare att söka sig till organisationen. Ett starkt arbetsgivarmärke kan vara avgörande för hur levande en organisation blir, människan är en av de främsta resurserna i en organisation och medarbetarna är en viktig ambassadör.I Norrbottens läns landstings medarbetarundersökning från 2014 signalerar medarbetarna ett missnöje gentemot arbetsgivaren. Denna studie, som är en master uppsats i Human Resource Management med utgångspunkt i Sociologin, avser att genom kvalitativa intervjuer med anställda inom hälso- och sjukvården undersöka medarbetarnas upplevelser av arbetsgivaren för att identifiera vad missnöjet kan bero på.Resultatet visar att medarbetarna är nöjda med sin arbetsplats, med sina arbetsuppgifter och med sina kollegor.
Arbetsmiljö inom äldreomsorgen : en studie om enhetschefens resonemang och förhållningssätt i arbetsmiljöfrågor
The occupational group who works in the care of older people in Sweden is an exposed group since the work is often defined as a strenuous profession, both physical and psychically, and this puts comparatively many workers on sick leave. To promote good health, as well as prevent bad health is the main purpose of the work environment development. The attitude of the care manager towards work environment development may have a significant impact on the co-workers health. The purpose of the study was to investigate the attitude of care managers towards work environment development and the co-workers work environment and in the same time get knowledge in what issues they have a salutary approach respectively a pathological approach. Empirics were gathered from semi-structured interviews with six care managers from the care of older people administration in municipality of Kalmar.

Avfallshantering på byggarbetsplatser : Potential för en miljöeffektiv avfallshantering
This thesis concerns waste management on construction sites and was conducted on behalf of ICA Fastigheter.Areas of concern:How can an environmentally-efficient waste management system on construction sites be defined? What potential exists for exploiting the waste resources that are generated?How can the waste management be optimised by reducing the quantity of waste and by optimal sorting?How can the client of a project influence the waste management?The purpose of the work was to investigate sustainable waste management in the building and construction sector and to highlight waste as a resource from an environmental and economic perspective.The aim of the work was to define an environmentally-efficient waste management system, to analyse the potential that exists in waste management and to draw up guidelines for optimal waste management.The method consisted of a literature study, two visits to construction sites and four interviews.An environmentally-efficient waste management system means that the waste is managed in the following order of priority:Prevention Reuse Recycling Energy recoveryLandfill The prevention of waste is an important area that has not been adequately explored by the building and construction industry. The quantities of waste could decrease with the implementation of measures such as ordering materials in the dimensions required, prefabricated components, logistics centres with Just-In-Time deliveries, less and improved packaging and less wrapping. The reuse of waste materials and temporary apparatus as well as the use of a return pallet system are examples of reuse that reduces the quantities of waste.In most cases the source sorting work is a matter of course and the proportion going to landfill is down at a low level. The source sorting can be optimised by sorting all materials that can be reused and recycled to use them as a resource.
Numerisk simulering av hydroformning
Sedan hydroformning började användas inom plåtformning i början av 90-talet har den dragit mer och mer uppmärksamhet till sig framför allt inom bil- och flygindustrin. Processen kan med fördel användas istället för konventionell teknik dvs mekanisk stansning eftersom den kan skapa delar med bättre egenskaper till lägre kostnad. I hydroformningsprocessen pressar en hydraulisk vätska ut ämnet mot formen samtidigt som cylindrar trycker på vid ändarna av ämnet för att tillföra material där det behövs. Förhållandet mellan vätskans tryckökning och cylindrarnas axiella kraftökning är en mycket viktig del i processen. Två versioner av finita elementprogrammet DYNA3D användes för att simulera processen: en standardversion och en version med en adaptiv tryckökningsalgoritm.
för att förstå tänker jag på arabiska Arabisktalande barns möte med litteraturen i skolbiblioteket, en intervjustudie med åttaåringar och elvaåringar
The purpose of this study is to the increase knowledge and understanding of the meeting between children with Arabian as native language and a Swedish school library. The study is made as a qualitative investigation built on interviews with eight-year-olds and eleven-year-olds. Only the childrens needs and views are considered. The study is centred on twelve key issues and aims to document the childrens thoughts and views of reading as well as their reading habits and their use of the school library. Through the childrens own words their evaluation of reading and literature, their abilities to assimilate the text and their de facto use of the books can be known.
