This report aims to provide an insight into the particle physics of today, and into the research that goes on within the field. The focus is partly on the recent discovery of the Higgs boson, and partly on how software can be used to simulate processes in particle accelerators. Basic concepts of particle physics and the search for the Higgs boson are discussed, and experimental results, including those from the Large Hadron Collider, are compared with simulations made in MadGraph 5. Furthermore, simple new models of particle physics are created in FeynRules, in order to make simulations based on the models. To support the presentations of these aspects, some of the underlying theory is built from the ground up.

In most countries, the dairy industry focuses on the volume of milk produced instead of its composition. This results in a high content of water and a lower proportion of fat and protein. A high proportion of water is not desirable when processing the milk into various dairy products like cheese, cream and milk powder. High water content also increases the costs for transport and storage, and also an unnecessary, albeit marginal, strains on the world?s water reservoir.

I dagens högteknologiska samhälle kryllar hemmen av datorer i olika former. Fler och fler använder en smartphone dagligen och inser kanske inte vilken datorkraft som finns inuti det de håller i handen. I detta arbete presenteras tillämpning av signalbehandlingsteknik (DSP) som har potentialen att på ett effektivt sätt sänka kostnaden för tillverkning av högtalare genom att kombinera dessa med ett filter som kontinuerligt kompenserar för högtalarens tillkortakommanden och skavanker i ljudåtergivning med hjälp av en dator.I detta arbete väljs komponenter och konstruktioner för högtalare inte bara efter prestanda. En avvägning görs mellan å ena sidan vad som gör högtalaren så billig som möjligt att bygga, och å andra sidan vilka av konstruktionens prestanda som är möjliga att optimera i efterhand med DSP. Därefter används digital signalbehandling för att kompensera de brister som finns och på så sätt återskapa den ljudkvalitet som förväntas av högtalaren.I denna rapport beskrivs arbetet med en prototyp som är framtagen enkom för användning tillsammans med DSP.

Pheromones are chemical substances representing very specific signal messages within a species. Although a lot remains unknown about their precise effects, it is known that pheromones influence the behaviour of the receiver. Since the mid 1990s, when it was first possible to synthesise analogues of two fractions of feline facial pheromone, F3 (Feliway®) and F4 (Felifriend®), these have been used in so called pheromonotherapy to treat behavioural problems in cats. The initial use of pheromones for specific behavioural problems has been extended to cover the wide field of stress related issues. This studycontains a questionnaire where veterinary nurses and surgeons at 50 Swedish veterinary hospitals and clinics were asked about their use of synthetic analogues to feline facial pheromones in the care and treatment of cats.

The forest is characterized by many different values such as those related to forest productivity which are of a big importance for Swedish economy. History has proved that forest resources had helped the country in the transition from the agricultural to the industrial society. Today Swedish forest industry is among the strongest in Europe and significantly contributing to the Swedish export. The industry provides many direct and indirect job opportunities and is one of the biggest employers in the industry sector. It is also worth to notice that the forest can also generate an additional income for the owners, even if the forestry isn?t their primary income source.

Detta kandidatarbete undersöker hur narrativa strukturer inom spel fungerar i kombination med varandra, hur dessa kan användas tillsammans och vad som förändras i en spelproduktion. Syftet är att undersöka trippelnarrativ som metod för användande av flera narrativa strukturer i ett och samma spel och att ta reda på hur det kan tillämpas i en spelproduktion. Vi genomförde en undersökande produktion där vi utvecklade en prototyp av ett spel med en trippelnarrativ struktur för att sedan diskutera och resonera kring användandet i spel.

Elektronisk mobbning har under den senaste tiden blivit uppmärksammat i media. I och med att det är ett ökande problem finns också ett behov av att forska inom området. Inom det sociala arbetet möter man dagligen människor som är aktiva användare av digital kommunikation, vilket gör att kunskap inom området är angeläget. Syftet med studien var att undersöka unga Internetanvändares syn på e-mobbning, samt deras upplevelse av detta. Syftet med uppsatsen var också att undersöka maktaspekten i e-mobbning utifrån en strategianalytisk utgångspunkt.

Children's Need In Focus (BBIC) is a processing and documentation system used in child welfare cases to investigate, plan and monitor interventions. The BBIC has had a breakthrough in Sweden and out of the country's 290 municipalities, there are 284 that use the system daily as a tool in cases involving children. The purpose of this study was to examine how social workers experience the BBIC as a working system and what strengths and weaknesses there are in the BBIC concept. We wanted our study to examine how the BBIC could possibly enhance the quality of childcare matters, but also how the BBIC could potentially increase children's participation in cases. We have performed qualitative interviews with eight social workers who work in four different municipalities where the BBIC is applied daily.

Today?s cell phones include more and more functionality, it is no longer uncommon to be able to connect to the Internet or take photos with the cell phone. In this thesis the question is if the cell phone users are interested in this new functionality. Are there people who are interested in a cell phone that in this thesis is called ?Basmobilen? (the entry level phone), which include the following functions; phone call, SMS, phone book, calling lists, clock and the possibility to change the call signal.

The digital flexor tendon sheath (DFTS) is an important anatomical and functional structure in the horse. Disorders of the DFTS can result in devastating consequences for the horse. During the last decade, the possibilities to diagnose and treat disorders of the DFTS have been argumented. The main purpose of this paper is to describe the technique of tenoscopy and it's applications. The aim is also to review the anatomy of the fetlock canal, the differnet types of tenosynovitis, proximal annular ligament constriction and to describe the ultrasonographic examination of the DFTS..

 I takt med att IKT-utvecklingen accelererat i samhället har också kravet ökat på effektivt användande av IKT i skolan. Syftet med denna undersökning har därför varit att studera hur en kommun implementerar IKT-stöd i sin grundskoleverksamhet för att stötta pedagogerna i deras arbete med att utveckla elevernas digitala kompetens. Undersökningen har genomförts som en deskriptiv fallstudie i form av kvalitativa intervjuer med sex nyckelpersoner i organisationen. Den bild som tidigt framträdde var hur otroligt komplext IKT är i förhållande till skolans värld. Det finns många aktörer och intressenter på en arena som ständigt förändras av den nya teknikens växande framfart.

GPS (Global Positioning system) and GIS (Geographical information system) has been used for planning and inventory in the forest sector for more than ten years. The last years the development has come to equip harvesters and forwarders with GPS and GIS (GIT). The goal with this study was to reach a basis for decision, how Stora Enso Skog should continue its investment in GPS and GIS in harvesters and forwarders. To reach this basis for decision, possible advantages and benefits, disadvantages and problems in the harvesting process was evaluated. The study was made as an interview study with four harvesting managers and ten machine teams. To secure the quality of the results an interview questionnaire was made before the interviews were done. The results showed that GIT will make the harvesting managers work easier.

Music today is a big part of a person's everyday life and can influence emotions as wellas initiative and motivation. This effect together with development in technology hasled to that music today is accessible and can be played from a large amount of differentkinds of products. This in turn has meant that the demand for smaller audio playbackdevices is greater than ever.The goal of this project is to develop a concept for energy-efficient speakers withwireless communication that has the ability to obtain and play high quality music. Thespeakers will use the latest available technology and at the same time, using digitalsignal processing, have a low environmental impact through high energy efficiencyand low power consumption. Parallel to this work a pilot study will be conducted tosee trends in listener preference of sound.The result achieves the goals pledged while power consumption in sleep mode is solow that they meet the demands of tomorrow.

En kvalitetsförbättrande metod som senaste åren blivit vanlig inom Hälso- och sjukvård är Lean Healthcare - en verksamhetsfilosof som går ut på att eliminera slöseri och skapa värde för patienterna. I takt med att informationssystem och informationsteknik (IT) har utvecklats har informationsförsörjning fått en allt viktigare roll i vårdprocessen. Tidigare undersökningar visar dock att vårdpersonalen upplever att det finns många brister kopplade till informationssystem och IT. En explorativ fallstudie genomfördes där kvalitativ data samlades in med hjälp av intervjuer, dokumentstudier samt observation. Syftet var att beskriva hur informationsförsörjningen påverkats i ett kliniskt mikrosystem och i en vårdprocess som infört Lean.
