Popular Abstract in Swedish Idag har kravet på kortare ledtider i bilindustrin dramatiskt ökat behovet av effektivare utvecklingsmetoder vid varje steg i processutvecklingskedjan. För att minska de långa ledtiderna för framtagning av ett formningsverktyg har man introducerat Finita Element (FE) simulering av formningsprocessen. Även om FE-simulering används inom bilindustrin idag finns fortfarandeToday, shortened lead-times in the automotive industry have dramatically increased the need for more efficient development methods at every stage of the process development chain. In order to decrease the long lead-time for producing a forming tool, sheet-metal-forming simulation was introduced. Even though sheet-metal-forming simulation is widely used in the automotive industry today, there are s

The European Spallation Source (ESS) is a planned neutron source to be built in Lund, Sweden, which is planned to produce the first neutrons in 2019. It will have an average beam power at the target of 5 MW, an average current along the linac of 50 mA, and a pulse repetition rate and length of 20 Hz and 2.86 ms, respectively. The linac will have around 200 LLRF stations employed to control a varie

Abstract This paper addresses the importance of networks for entrepreneurs in bankruptcy, based on interviews with entrepreneurs who have experienced at least one bankruptcy. Analysis of the interviews reveals two discursive themes: entrepreneurship and bankruptcy. Entrepreneurship is expressed in terms of initiative and of contacts in business contexts; bankruptcy concerns economic marginalizatio

This thesis evaluates the feasibility of designing a coprocessor to accelerate multimedia functions in the OpenMAX standard. OpenMAX is a new standard from the Khronos group, a member funded industry consortium, to integrate the most popular multimedia functions like MP3, MPEG-4 and H.264 under one roof. It provides royalty-free API that helps in developing and/or accelerating the specified standa

The purpose of the present dissertation is to problematize the choice of content in the subject Tourism in Swedish upper secondary school, and it thereby aims to contribute to a discussion of the subject content and its implications. The dissertation is informed by an international tradition of tourism education research, as well as by research pursued within a Swedish curriculum theory tradition.

This paper shows a novel methodology to improve unrolled CORDIC architectures. The methodology is based on removing adder stages starting from the first stage. As an example, a 19-stage CORDIC is used but the methodology is applicable on CORDICs with an arbitrary number of stages. The CORDIC is implemented, simulated, and synthesized into hardware. In the paper, the performance is shown to be incr
