Energy consumption reduction is today an important design issue for all kinds of digital systems. Offering both flexibility and efficient energy management, variable speed processor architectures are prefered for low energy consumption even in hard real-time systems. For this type of systems, the main approach consists in trading speed for lower energy while meeting all deadlines. For tasks with v

Periodic orbits of 3-d dynamical systems admitting a Poincaré section can be described as braids. This characterisation can be transported to the Poincaré section and Poincaré map, resulting in the braid type. Information from braid types allows to estimate bounds for the topological entropy of the map while revealing detailed orbit information from the original system, such as the orbits tha

In the previous chapters of the book, you will have seen multiple applications for using (and the benefits of using) a gaze tracker. In this chapter, you will be given more insight into how an eye tracker operates. Not only can this aid in understanding the eye tracker better, it also gives important information about how future applications might improve on current ones, by using more of the info

We have determined detailed elemental abundances and stellar ages for a sample of now 38 microlensed dwarf and subgiant stars in the Galactic bulge. Stars with sub-solar metallicities are all old and have enhanced alpha-element abundances - very similar to what is seen for local thick disk stars. The metal-rich stars on the other hand show a wide variety of stellar ages, ranging from 3-4 Gyr to 12

The trend of the service architectures developed in telecommunications today is that they should be open in the sense thatthey can communicate over the borders of different networks. Instead of each network having their own service architecture with their own applications, all networks should be able to use the same applications. 3GPP, the organization developing specifications for the 3G networks

Artikeln diskuterar en väsentligen nordamerikansk tanketradition som explicit eller implicit framställer den centrala antika filosofiska frågan – ”hur bör jag leva?” – som sin frågehorisont, och som gör det såväl teoretiskt, empiriskt som normativt. Det handlar om sociologer och andra samhällsvetare, men också om litteraturvetare och kulturkritiker, essäister och skönlitterära författare. ArtikelnThe article describes and analyses an essentially American intellectual tradition which explicitly or implicitly poses the central question of Hellenistic and Roman philosophy – ”how should I live?” – as its main theme and concern, and which discusses the matter theoretically, empirically, and normatively. The tradition includes sociologists and other social scientists, but also cultural theorists

We study distributions F on [0, infinity) such that for some T less than or equal to infinity F*(2)(x, x + T] similar to 2F(x, x + T]. The case T = infinity corresponds to F being subexponential, and our analysis shows that the properties for T < &INFIN; are, in fact, very similar to this classical case. A parallel theory is developed in the presence of densities. Applications are given to ran

The article investigates the notion of transport biofuels, their possible advantages and disadvantages in comparison to traditional fossil fuels, and sustainability requirements that need be stated to their quality and production methods from a legal perspective. The research results indicate that the understanding of what makes the quality and production of transport biofuels sustainable is still

Microglia respond to focal cerebral ischemia by increasing their production of the neuromodulatory cytokine tumor necrosis factor, which exists both as membrane-anchored tumor necrosis factor and as cleaved soluble tumor necrosis factor forms. We previously demonstrated that tumor necrosis factor knockout mice display increased lesion volume after focal cerebral ischemia, suggesting that tumor nec

Before the coming Durban Review Conference against racism the universality in the Universal Declaration of Human Rights is questioned as a result of the intense conflict between freedom of expression and religious liberty particularly according to the concept of defamations of religions. The conflict is declared to be the opposition between “universal ideal” and “cultural relativism”. In this inve

A study about the positive and negative effects of bilingualism in bilingual adults.

Sedan EU bildades har unionen haft en central roll för att integrera medlemsstaterna och har också som en effekt av detta haft ett ökande inflytande på medlemsstaternas nationella lagstiftning. Dessutom har denna utveckling lett till juridiska överväganden avseende hur EU:s författningar ska tolkas och verkställas och hur denna integration ska kunna säkerställas. Det finns fyra friheter i EU-fördrSince its inception, the EU has had a pivotal role in integrating the MS between each other and also has had an increasing influence on the national legislation of these states. Moreover, this process has naturally led to legal concerns on how to interpret the EU law and how to impose it to secure its integration for the future. Furthermore, in order to impede and hinder MS from protecting and ben

Crowdfunding is often considered as a financial source to close the early stage financial gap of new ventures. However, there is little research on its impact regarding other liabilities new ventures face. The aim of this study is to find evidence on how crowdfunding can provide new ventures with additional value apart from financial resources. For this purpose, the concept of liability of newness
