Popular Abstract in Swedish Inom området datorgrafik undersöker man hur virtuella scener kan omvandlas till verklighetstrogna bilder. För interaktiva miljöer, som exempelvis datorspel, måste en ny bild vara genererad och klar att visas på skärmen mellan 30-60 gånger i sekunden för att upplevelsen ska kännas responsiv och för att rörelser ska flyta på ett naturligt sätt. För att datorn ska hinna meThe field of computer graphics refers to the use of computers to generate realistic-looking images from virtual scenes. Graphics processing units use an algorithm known as rasterization to compute images of scenes viewed from a virtual camera. The commonly used pinhole camera model does not account for the imperfections that stem from the physical limitations in real-world cameras. This includes,

The aim of this study is to explore the use and perceived unfilled need for assistive technology (AT) for everyday life in three age-groups during the ageing process. Data on use and perceived unfilled need for AT from three age-groups were used; the very old age-group; 81-90, n=314, the oldest old age-group; 85-94, n=154 and younger agegroup, 67-71. The results show that the proportion of users h

Abstract in UndeterminedA method is described for assessing occupational exposures to chromium aerosols; it involves four procedures. The first, proton induced X-ray emission (PIXE), measures the total chromium,. The second, electron spectroscopy for chemical analysis (ESCA), measures the oxidation state of the particle surfaces, and the third, which uses sym-diphenylcarbazide (DPC), measures the

In the 2000s, Sweden has experienced a veritable explosion of feminist performing arts. Although feminist actions, theatre, shows and performance existed previously, feminist events with a distinct political and activist approach have emerged strongly in the current decade. Feminist culture festivals are held in rapid succession, and feminist performance, dance and theatre occasionally attract bro

A 2.4-GHz CMOS VCO is presented employing pMOS transistors as voltage-controlled capacitances and on-chip hollow spiral inductors. The design was implemented in a standard digital 0.8 μm CMOS process and exhibits a 15% tuning range at 2.5 V supply voltage and 9 mA supply current. Phase-noise measurements show a phase-noise of about -118 dBc/Hz at 1 MHz from the carrier

Abstract in UndeterminedIn this study, we validated comfort and limit temperatures of four sleeping bags with different levels of insulation defined according to EN 13537. Six male subjects and four female subjects underwent totally 20 two-hour exposures in four sleeping bags at four intended testing temperatures: 11.2, 3.8, 2.1 and -9.0 °C. The subjective perceptions and physiological responses o
