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.

Aerated steam treatment is a modern and environmental friendly method for seed borne fungus sanitation, mainly used on cereals. The method involves exposure to heat and high humidity, factors which are known to induce a fast ageing of seeds, thus resulting in reduced storability. This thesis clarifies the interdependence between seed age and the aerated steam treatment intensities. Two studies were carried out in this thesis. In the first study the storage longevity of seeds treated with aerated steam was examined. The second study investigated the shelf-life of the pre-tests used to determine the aerated steam treatment tolerance of a seed lot, by testing the treatment tolerance of seeds aged prior to the treatment.

Syftet med studien är att undersöka i vilken omfattning gymnasieelevers skolk är ett uttryck på brister inom skolans verksamhet. Utifrån syftet har två frågeställningar framkommit: Hur påverkar skolan som institution frekvensen av skolk? Vilket förändringsarbete bör ske inom skolan för att minska frekvensen av skolk? De perspektiv studien utgår ifrån är, kontextuellt samt ungdomskulturellt. Rapporten bygger på fem utförda fokusgruppsintervjuer med elever från årskurs två och tre på gymnasiet, samt sex enskilda semistrukturerade intervjuer med skolledning, elevhälsa och lärare. Materialet har bearbetats genom noggrann avlyssning av ljudinspelningar, med fokus på att finna likheter och olikheter i det empiriska materialet.

Forestry supply chains are a significant part of the Swedish economy. These supply chains are highly susceptible to storms damage. In late 2013 Sweden was hit by multiple storms. This leads to the possibility to research how supply chains react to the shocks that storms cause. The aim of this thesis is to research the costs that storms increase, the actions that are taken within the forestry supply chain, as well as possible benefactors from storms. This thesis bases on previous work on supply chain mapping and cost theories.

Our purposes with this essay was to increase our knowledge about, and try to describe, how it happens when people get involved in gambling and becomes addictive to gambling, and what the way out of a gambling addiction could look like. Our framing of the question was: - How does gambling begin? - How does gambling evolve to an addiction and how does it go forward from there? - How do you leave a gambling addiction? Is there an experience of turning points? We did qualitative interviews with six former gamblers. Our main conclusions were that the initiation to gambling can be very different and still lead to similar effects. There seems to be a strong enticement surrounding the attributes of gambling, which are connected to developing a gambling addiction. The experiences of turning points were very palpable.

I denna rapport redogör jag för det praktiska examensarbete jag genomförde under vårterminen 2015. Jag har studerat antidrog och -alkoholkampanjer under 70-80-tal, kampanjen ?Det finns många anledningar att inte testa knark? samt kampanjen ?Langarmytologi? som lanserades våren 2015. Mitt fokus har legat på att undersöka film som medium när det gäller antidrog och -alkoholkampanjer. Varför används just detta medium så ofta? Fungerar skräckpropaganda eller är humor det smartaste tillvägagångssättet? Jag har producerat tre korta filmer i programmen Adobe Premiere Pro samt After Effects där jag visualiserat det jag kommit fram till i mina studier. .

Virtual communities are a phenomenon that is becoming more common as the information technology comes with in reach for the general public. This report will bring the theories and construction of a virtual community together. The purpose of this report is to describe the different theories that have emerged from the research within this field and to examine the work procedures that have been used during the development of a site for a MDA-community. The MDA-website is a homepage on the Internet that was developed to bring the students closer together. The report describes the work of the project group, why the website was not completed and at the end the theories are looked at on the basis of the construction of the website..
