Optimering av multiprocessorsystem med hjälp av schemaläggning
A well known optimization-problem of multiprocessor system is scheduling of tasks. In this paper I use a variant of previous known algoritm, (Fast Critical Path) for scheduling real-time tasks on a multiprocessor system. This is made in a simulation study in MATLAB. The system architecture is assumed to be a MIMD- machine, (Multiple Instruction stream Multiple Data stream) with bus-typologi and message-architecture. Scheduling was made on this system where the number of processors varying from five to ten.
Varumärkets betydelse - en jämförelse mellan hur unga och äldre påverkas i köpprocessen
The thesis strives to answer the question whether there are any differences between how young customers, in comparison with older, are affected by brands when buying different products. The purpose is to get a clearer idea about the brands' importance in the future and in that way also to give guidance to companies about how to best market themselves and there products.To answer the question, an experiment was conducted with 480 respondents taking a survey where they had to rate a product after reading a short text about it. Some of the texts stated that a specific brand was behind the product while some said the product was produced by an unknown brand.The result of the study was that young people showed a greater propensity of rating products with a brand higher than products without brands, in comparison with the older respondents. This gives reason to believe that brands progressively will become an even more important tool for marketers and an unmatched asset for companies in the future..
Konstruktion av mutterdragare för stora moment
This degree project was conducted in collaboration with Gremo AB located in Ätran.The aim of the project was to develop a solution to secure quality and to help assemblingthe locknut holding the vertical hinge on the harvesters and foresters from Gremo.At this time the nut is assembled manually by the aid of an overhead crane. The nut istightened differently from time to time, and there was no specified torque to which it istightened. Another present problem was the locking washer which sometimes getsdamaged during assembly, when this happens the procedure has to be started over fromthe beginning. The current assembly procedure is very time consuming and lengthy forthe employees.Our task was to design a machine that could tighten the nut to a specified torque with amargin of error of ± 3%. The assembly procedure will be held simple and the timerequired at a minimum.The project started by developing several principle solutions, the one solution that bestmatched our specifications were developed to a primary solution.Today we have started manufacturing and assembling our prototype.
Etiska dilemman på Stockholms Jobbtorg : Ur ett studie- och yrkesvägledarperspektiv
Syftet med denna uppsats var att undersöka hur studie- och yrkesvägledare på Jobbtorg arbetar med de dilemman som kan uppstå kring de etiska riktlinjerna. Författarnas hypotes har varit att det är svårt att tillämpa de etiska riktlinjerna i en målstyrd verksamhet som Jobbtorg. En kvalitativ metod har används där fem slumpmässigt utvalda studie- och yrkesvägledare på Jobbtorg Stockholm har intervjuats. Resultatet visar på att studie- och yrkesvägledarna upplever dilemman kring deras yrkesetik, men har utarbetat olika strategier för att hantera dessa dilemman. Det visade sig att studie- och yrkesvägledarna hade skapat sig ett stort arbetsutrymme kring studie- och yrkesvägledningen på Jobbtorg.

Prevention of diabetes type 2 among children and adolecents : Literature rewiew
The objective of this literature study was to describe the nurse?s preventive actions to prevent diabetes type 2 among children and adolescents in school age. It emerged from the analysis that the nurse is working according to three pillars; screening, lifestyle changes and counselling/education. This result showed that what often increase difficulties when working with screening are: undefined guidelines, lack of time and resources. Overweight/obesity is one of many indicators to develop diabetes type 2, therefore it is important that both BMI and waist are measured.

How do they experience that the school situation functions and how would they as teachers like the school situation to function for these young people at school?The result shows that special teachers have an extremely important function to fulfil. Those interviewed felt that there are sufficient resources available, for example guidance and further education for techers as well as both support and means for helping the young people.However, every teacher does not understand this handicap.
Lakvattenrening och kontroll vid deponier : granskning och sammanställning
If not purified leachate from landfills would cause damages on the environment. At most landfills in Sweden local treatment of leachate is achieved, at the rest the leachate is transported to sewertreatment. While no comprehensive legal provisions for discharge exist in Sweden there is a difference in discharges between the installations for landfill. If no comprehensive legal provisions is produced guidance must improve.Treatment of leachate and self monitoring system at fifteen installations in Sweden has been studied and compared. A study of literature about different treatment solutions has also been performed.
Förstudie av gränssnitt och styrprogram till SD-180
En av Glimek AB:s mest förekommande maskiner är SD-180 som används för degavvägning. Den finns i flera olika varianter. Den enklaste har enbart start- och stoppknapp och en potentiometer för att ställa hastigheten och en mer avancerad variant har en operatörspanel där olika möjligheter till inställningar finns.Konstruktionen på denna maskin hade inte uppdaterats på många år och behövde en uppdatering av användargränssnitt, programvara och elkonstruktion. Arbetet har framförallt koncentrerat sig på användargränssnittet till panelen.En del av arbetet var att undersöka om det var möjligt att utesluta PLC ur konstruktionen och använda en mer avancerad programmerbar frekvensomformare. Eftersom det blev problem med lanseringen av programvara till frekvensomformaren och enbart en mindre bra fungerande demoversion fanns tillgänglig så var detta tyvärr inte möjligt.I arbetet har olika varianter på operatörspaneler utretts.
