Elektriskt system för detektion vid ballistiskt prov
The purpose of this thesis was to design an electrical system for use in a ballistic test at the Swedish National laboratory of forensic science (SKL). The detector unit would use four main parts: coilsystem, transmitter, reciever and indicator. The coilsystem would be based on a balanced system using three coils. One that creates a magneticfield and the other two will sense the differences when a metallobject is in the coilsystem. This report starts out by investigating possible solutions for this specific task followed by a description of the physics that the metaldetector use.
Isaac Newton och den matematiska naturfilosofin
In several scientific and technical educations today we meet mathematical studies in differential- and integral calculus. The classic mechanics is a foundation for the physics and it has made it possible for today's technical developments that we in our everyday life meet and make use of. The intention for this essay is to give a picture of the person behind this discoveries that changed the science and the world. Besides the purpose to bring the reader on a journey through Isaac Newton's life the main intention is to give an understanding of the way he discovered the binomial theorem, the differential- and integral calculus, the numerical methods Newton-Raphson's and Newton's interpolation-polynomial, Newtons identities and his classification of third-degree curves and elliptic curves. A derivation of Kepler's first law is also included..
Registrerad : - En förklarande studie av Skånepolisens romregister
In 2011, a crime prevention initiative was undertaken by the Swedish police department in Scania. Two years later, the Swedish media reported on this initiative, claiming that it had been intended as an ethnic registration of Romani people. This revelation resulted in a great deal of controversy and sparked a national debate on the issue of ethnicity and public registration in Sweden. The police in Scania had difficulties explaining the purpose of such a registration effort, and could not provide evidence that it had been legitimate and legal. This paper will attempt to explain the motivation behind the original police initiative with a theoretical analysis based on assessments from public authorities.
Talgoxar : inomartskonkurrens vid trädplacering och födosök
Min studie handlar om hur inomartskonkurrensen ser ut hos talgoxen, Parus major, när det gäller födosök, trädplacering och säkerhet. Är det så att fåglarna lever i ?mansdominerade? samhällen, att det är hanen som söker föda på de bästa och säkraste delarna av trädet jämfört med honan. För att undersöka detta har 31 talgoxar studerats under nio dagar i sin naturliga miljö. Här noterades var i trädet de placerade sig och hur de sedan förflyttade sig i tre födosök.

Budskap i förändring : En studie av internkommunikationen vid Sveriges Lantbruksuniversitet
This thesis tries to explore how different strategies of internal communication are used in actual situations within an organization. Specifically, the purpose is to investigate how the internal communication within the Swedish University of Agricultural Sciences (SLU) has been carried out during their work to change their organizational structure, and, how this can be understood in terms of existing theories for strategic communication. The research questions explored are:What are the chosen strategies used to communicate the changes internally?How can these strategies be understood in terms of existing theories?What are the views of the employees on the communication and what are the relations between their views, the chosen strategies and existing theories?The theoretical ground work chosen is mainly the work by Cornelissen (2008), Dalfelt (2005), Johansson (2011) and Larsson (2008). The method chosen for the empirical part of the study is semi-structured qualitative interviews.
Mag-tarmkanalens anatomi och fysiologi
Detta examensarbete handlar om mag-tarmkanalen och är uppdelat i två avsnitt. Den första delen handlar om mag-tarmkanalens uppbyggnad, rent anatomiskt men också hur den ser ut histologiskt. Histologin är bara ytligt behandlad då den endast är med som förklaring till vissa händelser inom fysiologin. Den andra delen, fysiologidelen handlar om de olika delarna i mag-tarmkanalen, deras funktioner och vad som reglerar dessa. I fysiologiavsnittet behandlas också nedbrytning och absorption av de olika näringsämnena..

Konstruktion av upprätningssystem för CICLoPE
Today there is no way of measuring or simulating turbulent flow in high Reynolds numberenvironments. The computational power required to simulate these conditions is not expectedto be available for several decades so instead the CICLoPE project aims at solving thisshortage by the construction of a long carbon fiber wind tunnel in which real measurementscan be made. To do accurate measurements it is of importance that the wind tunnel, 0.9 metersin diameter and 110 meters long, is as straight as possible.This master thesis treat the design and construction of a device which may be used to align thetunnel along a reference laser beam. A design is presented which allows the pipe to be alignedwithin about a quarter of a millimeter along its entire length. Contents span over severalscience fields such as physics, mechanics, control theory and electronics.The result is a theoretically correct design.
