The Arena and the Entrepreneurial City builds on a microhistory of the collaboration between public and private organizations in the creation of two public sports arenas. Several new arenas have been built in Sweden during the last 15 years and many of them have received a lot of attention because of cost overruns and design flaws. Previous research shows that there are no economic incentives for

Popular Abstract in Swedish Ökat antal patienter som lider av kärlsjukdomar behandlas idag med interventionella metoder istället för kirurgi. Dessa metoder populärt kallade ballong sprängningar, kombineras numera oftast med inläggande av ett metallnät (stent) som hjälper till med att förstärka kärlväggen, så den inte skall falla ihop efter ballong vidgningen. Oavsett vilken metod som används, kompBackground: Restenosis is the most frequently occurring adverse event after percutaneous intravascular treatment of atherosclerotic lesions, which limits long-term patency of the intervention. Objective: The aim of the study was to evaluate if minimizing vascular injury during treatment by insertion of self-expanding stents or modifying the reparative mechanisms by local drug delivery can reduce r

In this paper we investigate how intrinsic camera calibration and hand-eye calibration can be performed on a robot vision system using the simplest possible motions and a planar calibration object The standard methods on plane-based camera calibration are extended with theory on how to use pure translational motions for the intrinsic calibration and we see how hand-eye calibration can be performed

Popular Abstract in Swedish Denna avhandling rapporterar om karakterisering och tillmpningar av extrem ultraviolett (XUV) strålning som genererats av övertonsgenerering samt i en frielektronlaser. Övertonsgenerering är en process som uppstår när en kraftfull kortvarig laserpuls fokuseras i ett gasmedium. De laserpulser som används är bara några femtosekunder (10−15s) långa och har en våglängd i This thesis reports experimental studies performed with two advanced coherent XUV sources with ultrashort pulse duration, high-order harmonic generation and seeded-free electron laser. High-order harmonic generation (HHG) is the generation of overtones of a fundamental laser pulse in a medium, e.g. noble gases. The emitted radiation has a high degree of transverse coherence, and pulse lengths in t

Experiments on a modern DI Diesel engine were carried out: The engine was fuelled with standard Diesel fuel, RME and a mixture of 85% standard Diesel fuel, 5% RME and 10% higher alcohols under low load conditions (4 bar IMEP). During these experiments, different external EGR levels were applied while the injection timing was chosen in a way to keep the location of 50% heat release constant. Emissi

Popular Abstract in Swedish Boken belyser, genom tematiska studier av centrala Dylantexter från de händelserika åren 1961-67, Bob Dylans konstnärskap och utveckling från politisk intresserad protestsångare till mera svårtillgänglig, modernistiskt influerad sångpoet. Avhandlingen inleds med en exposé över det amerikanska 60-talet och folkmusikens framväxt. Bokens andra och tredje kapitel behandlar Bob Dylan (b. 1941) became known as an enfant terrible and a regenerator of rock lyrics already in the tumultuous 60´s. His constantly shifting roles as musician and songwriter, combined with his notable reserve, have led to the growth of a plethora of myths surrounding his person and work. His lyrics, accompanied by an increasingly original rock backing, based on folk music and rhythm & blues

Wireless communications are really poised to see major improvements in terms of network capabilities. The next generation of wireless services, besides improving the overall capacity, will create new demand and usage patterns, which will in turn, drive the development and continuous evolution of services and infrastructure. Future wireless networks should have transparent roaming, meaning having a

Background: The adoption of air conditioning (AC) is growing rapidly in developing countries across the world which puts a high burden on electricity distribution systems. This development is mostly driven by income growth and building design, but also due to increasing outdoor temperatures and to provide indoor thermal comfort. Current indoor thermal comfort standards are based on western clothin
