Optimering av testning av säkerhetskritiska funktioner
Inom industrin används olika testmetoder för att uppnå hög kvalitet i mjukvarukontrollerade system. Kvalitetskraven är särskilt höga för säkerhetskritiska system t.ex. styr- och reglersystem i fordon. I det här examensarbetet används två analysmetoder (Fault Mode and Effects Analysis och Fault Tree Analysis) för att ta fram ett nytt säkerhetstest för ett broms- och växlingssystem som Scania tillverkar. Det studeras även hur formella metoder kan användas för att ytterligare öka kvalitet ochh tillförlitlighet.
Färgval hos blomkrabbspindeln (Misumena vatia) med och utan konkurrens
The colour choice of spiders and the effects of competition on this phenomenon were examined in the laboratory using the sit-and-wait predator goldenrod crab spider (Misumena vatia, (Thomisidae)). This species can be both white and yellow (could also change colour) and it was here examined whether individuals preferred to sit on flowers which has the same colouration as their bodies. I found that M.vatia showed preference for flowers that matched their own body colour, but when competition was introduced this preference disappear. It seems, however, that position is a factor that can influences the substrate decisions of M. vatia, where the edge of the flower is preferred..
En studie om de svenska riksdagspartiernas ställningstagande i EMU-frågan inför folkomröstningen år 2003
Based on widespread public debate prior to Swedish EMU-referendum 2003, the main purpose of this thesis is to examine and analyze the standpoint of the Swedish parliamentary parties in the EMU-issue, from perspektive of the following questions;1) What is the official standpoint of the parliamentary parties in the EMU-issue?2) What claimed effects of a Swedish EMU-membership or non-membership have the parties presented?3) What rifts can be found within the parties, in relation to their official standpoint in the EMU-issue?The Sweidish parliamentary parties´ standpoint in the EMU-issue will be analyze from the point of view of a number of current theories. These theories are basically democrazy theories that all have transnationalization and Europeanization as a common ground.The conclusions are, among others, that the parliamentary parties` standpoints in the EMU-issue are based on ideological values about whether or not a Swedish EMU-membership is good for Sweden. The Liberal Party, the Christian Democrats, the Moderate Party and the Social Party have a positive view on EMU and a deeper European integration, and basically value the economic efficency of the EMU higher than democratic decision making and a national currency and monetary policy. As for the EMU-critical parties such as the Centre Party, the Green Party and the Left Party, their view in the EMU-issue can be regarded as more nationalistic, since they say no to an exapanded financial cooperation.
Effect of botanically diverse pastures on the milk fatty acid profiles in New Zealand dairy cows
Botanically diverse pastures are commonly used in New Zealand to reduce the ruminant environmental impact by reducing the methane production from the rumen digestion. In order to evaluate the effects diverse pasture species have on the milk fatty acid profile seventy-two lactating Friesian-Jersey crossbred dairy cows were used in a randomised block design with two replicates of six treatments. Six different pasture mixtures were fed at a daily allowance of approximately 15 kg DM/cow/day. The mixtures were categorised as either a simple or a diverse pasture. The simple mixtures all contained white clover with the addition of either a standard diploid perennial ryegrass (RG), a diploid high sugar ryegrass (HS) or tall fescue (TF).
"Då rökte jag på. Sen började jag lite med tjack och sånt också." :en studie om hur ungdomars missbruk påverkar familjen
The purpose of our report was to analyze the effects of youth drug abuse on the families concerned. Youth drug abuse made us wonder about the effects on the family as a whole, of those involved with drug abuse. To answer this question, we decided to employ an empiric study in the form of interviews with four teenagers, five parents and four drug counselors. Because our intent was to understand rather than try to measure the problems involved, we decided on a qualitative method. Our method built upon semi-structured interviews using open questions, where the interviewees were free to express their own thoughts and opinions.
Marknadsföring i podcast
Podcast is a new audio media in Sweden and has become larger and increasingly more popular in the past few years. In line with this, companies have seen the opportunity to use this type of marketing in the new coveted media and have created a new marketing tool in the form of sponsorship. Previous studies in this field indicate that this is a very effective method to reach a broad audience, but it still is a relatively new area with very little research in existence today. This study is an analysis of how receptive listeners are to marketing through podcasts and the ability companies have to create a sustainable and effective strategy for successful marketing through this type of medium. The collection of data for this study consists of two different qualitative interviews, the first one with listeners that were chosen, and the second with the sponsor company for two of the largest podcasts in Sweden. The essay´s empirical evidence shows how receptive listeners are to marketing via podcasts, what their podcast habits look like, what form of approach in marketing they prefer, and how often they take part in different offers. From the interviews with listeners and sponsoring companies in the study, it is concluded that the best and most effective strategy for marketing through podcasts is to weave advertising in the conversation and therefore increase the credibility and disturb the listener as little as possible.

Kommunikation i multiagentsystem
Communication is an important part of any multi-agent system. There are
different ways of communicating and they have different effects on a
multi-agent system. This project describes and evaluates two different ways of
communication, implicit and explicit. To compare the two methods, two
experiments have been executed. The result of the experiments have been
compared and discussed.

Femtio Nyanser av Co-branding - En kvantitativ studie om effekterna av co-branding på konsumenters varumärkes- och produktutvärdering beroende av kvalitetssegment och hedoniska shoppingmotivationer
The retailing industry has an extremely high density of brands. In order to differentiate its offer, both retailers and suppliers, are constantly forced to come up with new ways to launch their products. A collaborative strategy between two brands is called co-branding, which means that both the private label and the supplier's brand are displayed on the new product packaging. Several studies have shown that a co-branding strategy is successful, but many operators are still reluctant to use co-branding in fear of long-term losses due to potentially damaged business relations. The objective of this study is to explain how the product- and brand related value for customers, retailers and suppliers is affected by co-branding between private labels and national brands.

Förekomst av leukocyter i råsperma hos semingaltar :
Detection of leukocytes in semen from boars is part of the routine control of semen quality. Leukocytes in semen can cause damage to spermatozoa that leads to impaired fertilization. In the artificial insemination (AI) industry there are standard routines for the quality control of the boars and of the neat semen before use. Since 2001, Quality Genetics has not done the leukocyte examination on semen samples from boars which are used for the production of pigs for slaughter.
The purpose of this study was to investigate the occurrence of leukocytes in semen from AI-boars. The questions addressed were whether there are boars that have leukocytes in their semen and how frequently it occurs and, moreover, if there are differences between breeds, or even between individuals whose semen was checked before use in AI-dose production compared to those which were not.
The study included a total of 135 AI-boars, of which 67 were Hampshire, 35 Yorkshire and 33 Landrace, all belonging to Quality Genetics AI-station in Hållsta.
