A new approach to optimize full custom, fixed coefficient bit-serial filters aimed at high sample rate and low power consumption is presented. The idea is to trade the filter order with the coefficient length. To show the results two filters were designed and implemented, one as a minimum order filter and the other as a minimum coefficient filter. Measurements shows that a ten fold increase in sam

En undervisningsform som blir allt vanligare vid högskolor och universitet är seminariet. Där deltar de studerande aktivt genom att skriva uppsatser, rapporter eller pm och sedan presentera och diskutera dessa. Detta kursmoment skiljer sig på många sätt från de kursmoment där tyngdpunkten ligger på inläsning med kunskaps¬kontroll i form av skriftliga tentamina där studenterna besvarar ställda fråg

Compressed sensing (CS) is a universal technique for the compression of sparse signals. CS has been widely used in sensing platforms where portable, autonomous devices have to operate for long periods of time with limited energy resources. Therefore, an ultra-low-power (ULP) CS implementation is vital for these kind of energy-limited systems. Sub-threshold (sub-VT) operation is commonly used for U

A brief popular article, in Danish, about how researchers on socialist countries had to rethink their research projects after 1989, including the transition from socialist societies to postsocialist to now, post post socialist societies

Describes evolution of 'anticorruptionism' and the anticorruption 'industry' in which 'industry' is seen in contrast to local social movements 'craft'. Previously published in the journal Global Crime

Fuel economy and emissions are the two central parameters in heavy duty engines. High EGR rates combined with turbocharging has been identified as a promising way to increase the maximum load and efficiency of heavy duty spark ignition engines. With stoichiometric conditions a three way catalyst can be used which keeps the regulated emissions at very low levels. The Lambda window which results in

This paper describes a system to create animated 3D scenes of car accidents from reports written in Swedish. The system has been developed using news reports of varying size and complexity. The text-to-scene conversion process consists of two stages. An information extraction module creates a tabular description of the accident and a visual simulator generates and animates the scene.

Thirty images with added simulated pathological lesions at two different dose levels (100% and 10% dose) were evaluated with the free-response forced error experiment by nine experienced radiologists. The simulated pathological lesions present in the images were classified according to four different parameters: the position within the lumbar spine, possibility to perform a symmetrical (left-right

Abstract in French L’article pose la question de savoir s’il existe une corrélation entre le niveau grammatical et le niveau lexical dans la production écrite des apprenants du français. L’hypothèse nulle est que la langue étrangère se développe à tous les niveaux linguistiques à peu près simultanément. Ainsi, un apprenant qui se trouve à un stade grammatical avancé aurait aussi un vocabulaire (un
