This paper reports on an explorative test session performed at INPG during December 2005. During this session two different implementations of a virtual PebbleBox were explored freely. The purpose of this test was to explore the importance of different pa

BEAST is a bidirectional efficient algorithm for searching trees that performs soft-decision maximum-likelihood (ML) decoding of block codes. The decoding complexity of BEAST is significantly reduced compared to the Viterbi algorithm. An analysis of the asymptotic BEAST decoding complexity verifies BEAST's high efficiency compared to other algorithms. The best of the obtained asymptotic upper boun

Many universities have experienced an increase in the intake of students and at the same time cuts in the budgets for teaching. Many teachers have experienced that, for a number of reasons, they have to adjust their teaching or a course with short notice. These facts pose a challenge to the teachers’ agility in adapting to changes – and in doing it in a cost efficient way. We propose eXtreme Teac

Regional cerebral blood flow (rCBF) was measured by the 133Xenon inhalation method in nine male chronic cannabis users. The rCBF level in cannabis users was significantly (11%) lower than that of age- and sex-matched healthy controls. Four of the subjects were reexamined after 9-60 days of detoxification and showed a significant (12%) increase of the CBF level at followup. No significant regional

Idag är datorer viktiga verktyg för blinda personer men används mest som text maskiner. Den omfattande användningen av Internet som informationskanal har lett till en smärre revolution för synskadade personer genom att ge dem tillgång till information som

Popular Abstract in Swedish Fett som tas in i kroppen bryts huvudsakligen ned i tunntarmen med hjälp av ett enzym, lipas och dess regler-protein colipas. Colipas binder sig till lipas och gör att lipas fastnar på fett dropparna som emulgerats av gallsalter. Både lipas och colipas utsöndras av bukspottkörteln. I de gröna växternas blad finns kloroplaster som fångar upp ljus och därvid bildar syre oObesity is a major health problem in the world that increases the occurrence of type-2 diabetes and cardiovascular disease. The reason for obesity is a dysfunction in the regulation of energy balance. It has been shown that dietary fat induces satiety as long as this nutrient stays in the intestine. One important gastrointestinal satiety signal is cholecystokinin (CCK), released from the intestine
