The colors and contrasts of the nocturnal world are just as rich as those found in the diurnal world. This chapter describes a recent biomimetic advance inspired by the visual systems of nocturnal insects. Since the underlying principles of both animal and camera vision are similar, it is natural to try to mimic the neural processes of nocturnal animals in order to construct efficient computer vis

Popular Abstract in Swedish Något som kan låta motsägelsefullt är att en stjärna fungerar som en svartkropp. Med svartkropp menas ett objekt, vilkens energiförlust i form av elektromagnetisk strålning bestäms av föremålets temperatur och storlek. Våglängderna på strålningen som lämnar ett objekt bestäms däremot endast av temperaturen. En snöboll med temperaturen -10 C strålar 271 W m$^{-2}$ medanThe spectra of symbiotic stars are shown to frequently contain numerous fluorescence lines caused by Photo-excitation by Accidental Resonance (PAR). So far, most work involving fluorescence in stellar spectra has been assigned to the search of new PAR mechanisms, which can explain the presence of certain emission lines. This is taken a step further as the PAR pumped emission lines are analyzed to

Popular Abstract in Swedish Den brittiske filmkritikern Robin Wood började publicera essäer om film 1960. Sedan dess har han ensam eller tillsammans med andra givit ut tretton böcker. Vid sidan av dessa har han skrivit flera hundra essäer samt medverkat i mängder med antologier och uppslagsverk. Speciellt betydelsefull har Wood varit för Alfred Hitchcocks status som den förmodligen mest omskrivne British film critic Robin Wood began to publish on film in 1960. Since then, he has written or co-written 13 books, and also published hundreds of essays and articles in books, in journals, and in different encyclopedias. At the same time, Wood has been a key figure in the development of what has become academic film studies. Wood was educated at Cambridge University, where he studied English lite

A permutor (interleaver) design method was proposed to show the existence of turbo codes with minimum distance growing logarithmically with the permutor length. It was found that the minimum distance of a turbo code depended on the structure of the permutor or on its life cycle structures. It was demonstrated that the method could be used for the construction of turbo codes with practical blocklen

Konkurrensrätten var viktig för Saltsjöbadsavtalets tillkomst. Arbetsgivarna var länge tveksamma inför avtalet. Lagstiftaren kopplade då ihop frågan om strejklagstiftning med regleringen av företagens karteller. Om staten tvingandes ingripa och reglera arbetsmarknaden med tvångslagstiftning så skulle företagen också få en hård kartellreglering på köpet. Genom att underteckna Saltsjöbadsavtalet sla

The Major Intrinsic Proteins, MIPs, constitute a large, ancient superfamily of membrane proteins that are found in all kingdoms of life. Most MIPs facilitate passive diffusion of water across biological membranes (aquaporins), although many channels are also permeable for glycerol and other small uncharged solutes, (aquaglyceroporins). Other substrates reported for specific MIPs are anions, carbon

The purpose of this book is to grasp the presence of Candomblé in the Brazilian society and more specifically in the city of Salvador da Bahia. Candomblé is an Afro-Brazilian religion practised by approximately thirty five million Brazilians, today. Brazil is a country whose cultural diversity is characterised by social contrasts. The Candomblé religion has culturally mixed roots and as both part

A model of event driven anticipatory learning is described and applied to a number of attention situations where one or several visual targets need to be tracked while being intermittently occluded. The model combines covert tracking of multiple targets with overt control of a single attention focus. The implemented system has been applied to both a simple scenario with a car that is occluded in a

Many full-reference objective metrics require that the original and the degraded video contain the same number of frames. Most codecs are not able to decode the video properly when the video is subject to packet losses and produce incomplete video files with lower number of frames than the original video. In this paper we present a simple method to reconstruct the degraded videos so that it has th

Popular Abstract in Swedish Akut leverskada och tarmen. Kväveoxids roll, och effekten av arginin- och probiotikatillförsel.Infectious complications with enteric bacteria are common in liver diseases and liver surgery. An increased bacterial translocation from the gut has been proposed as one underlying mechanism. In order to elucidate pathogenetic mechanisms and find possible preventive measures, we manipulated the enteric content and therefore we investigated the role of nitric oxide and the effect of arginine and pr

Nandita Singh and her colleagues look at children’s water rights in India. They argue for the exercise of the right to water by children by analysing the universal normative-legal framework and its difference to the local socio-culturally defined framework. They suggest that defining problems and designing actions only within the normative-legal framework can obscure understanding the critic

The duality principle in robust stabilization problems of rank one is studied. Several scalar examples are solved to illustrate the effectiveness and simplicity of the principle. Robustly stabilizing controllers that are designed by this method are usually of low order
