This thesis work contains a litterature study about electrical motors in general and how PWM-patterns for brushless DC-motors can be made. A suitable method has been implemented as a simulation model in VHDL. A simulation model of a brushless DC-motor which describes the phasecurrents, torque and angular velocity has also been made. The motor model made simulations easier for the complete PWM-system. The design was synthesised and tested with a prototypeboard including a SPARTAN II FPGA.

The purpose of the present quantitative study was to examine gender differences inperceived job satisfaction in two departments, with different work patterns, in a Swedishmanufacturing industry.

Våldet i samhället ökar. Detta våld sprider sig in på våra arbetsplatser så även inom hälso- och sjukvården. Sjukvårdpersonalen är utbildad i att vårda patienten utifrån omvårdnadsforskning och vetenskapliga medicinska rön. Verbala och fysiska aggressioner kan försvåra omhändertagandet. Syftet med denna litteraturstudie var att undersöka förekomsten och upplevelserna av hot och våld inom somatisk vård.

Mäns hot och våld mot kvinnor är ett allvarligt samhällsproblem. Syftet med studien var att utifrån aktuell forskning belysa faktorer som har betydelse i mötet mellan vårdpersonal och den våldsutsatta kvinnan. Metoden som har användts var en litteraturöversikt. Vetenskapliga artiklar söktes i databaserna Cinahl, Medline, HighWire press, samt psyk INFO. Resultatet består av 12 vetenskapliga artiklar publicerade mellan 1996-2007 .

Abstract The sociological problem of this C-essay is sociology of emotions.

 Inner resistanceThe aim of this study was to investigate the existence of an internal resistance to a work-related change in people who are long-term sick, and if this is related to an identification as ?long-term sick?. A second purpose to the study was to research in which way this internal resistance to a work-related change manifests and point to possible solutions. A qualitative study was conducted with interviews of experts and people on sick leave to illuminate the subject. The main result was divided into interviewed groups.

Denna studie i socialantropologi är baserad på intervjuer med två kvinnor anställda på en kvinnojour. Den handlar om deras uppfattningar och erfarenheter vad gäller uppbrottsprocessen för den kvinna som utsatts för mäns våld och hur hon blir bemött av polis och sociala myndigheter under uppbrottet. Kvinnan som ska bryta sig loss från mannen måste ofta ta kontakt med olika myndigheter för att lösa sin situation och dessa har visat sig agera på olika sätt. Deras kunskap är av stor vikt, men det är också nödvändigt att fundera på hur de personliga känslorna styr bemötandet och utgången av mötet. Människan är mån om att försöka anpassa sina känslor till situationen och tysta regler styr vad som är korrekt i en specifik situation.

The aim of this study was to identify and analyze the dominating discourse in the preliminary work of the Sex Purchase Act. In order to achieve the aim of this study we selected preliminary work of the Sex Purchase Act that was produced between 1977 and 1999.

This essay is a selective review of Nordic literature with the aim to explore contemporary conceptions of male-on-female rape, to increase the understanding of how these can construct ?a real rape?. To achieve this two questions were formulated: What circumstances can cause an incident not to be defined as rape? What circumstances can cause an incident to be defined as rape? Searches in international and Swedish databases led to initial selection of peer-review journal articles and dissertations that were reviewed against set criteria. These criteria were met by 8 studies, that were assigned codes, from which comprehensive categories were developed.
