The telecommunication industry has been successful in turning the Internet into a mobile service and stimulating the creation of a new set of networked, remote services. Most of these services now run or are supported by cloud computing platforms. Embracing cloud computing solutions is fundamental for the telecommunication industry to remain competitive. However, there are many legal, regulatory,

This study deals with listeners' ability to identify linguistic units from linguistically incomplete stimuli and relates this to the potentiality of vowel reduction in a word. Synthetic speech was used to produce stimuli that were similar to real words, but where the vowel in the pre-stress syllable was excluded. Listeners then performed a lexical decision test, where they had to decide whether a

In the search for renewable vehicle fuels several different gasoline additives have been discussed and reviewed. Today bioethanol is the most commonly used option, but isobutanol is being proposed as a better alternative by many stakeholders, due to its superior fuel characteristics, e.g. energy density, oxygen content and vapor pressure. The research project “Glycerol-based isobutanol” has invest

We introduce crossed product-like rings, as a natural generalization of crystalline graded rings, and describe their basic properties. Furthermore, we prove that for certain pre-crystalline graded rings and every crystalline graded ring A, for which the base subring A_0 is commutative, each non-zero two-sided ideal has a nonzero intersection with C_A(A_0), i.e. the commutant of A_0 in A. We also s

Popular Abstract in Swedish Trots att vi har ett mycket sofistikerat immunförsvar är infektionssjukdomar ett stort problem för alla flercelliga organismer. Varför har vi inte under evolutionens gång lyckats finna ett sätt att överlista virus, bakterier och andra parasiter? En förklaring är att immunförsvaret är kostsamt, dvs att ett kraftfullt immunförsvar inte bara ger fördelar i form av ökat skyA central assumption of theories of the ecology and evolution of immunological defence is that defence has not only benefits (in the form of resistance against parasites), but also costs. The aim of my studies was to investigate the nature and magnitude of costs of the vertebrate immune system, and to examine some of the consequences of these costs. First, I investigated the energetic cost of the

Popular Abstract in Swedish Pelagiska bakterier använder löst organiskt material som kol- och energikälla. Det lösta materialet kan ha sitt ursprung i intern (autokton) eller terrester (allokton) primärproduktion. Den här avhandlingen handlar om hur bakterier använder autoktont och alloktont producerat kol. Dessutom undersöker jag om det finns en koppling mellan kolkällans ursprung och strukturen Organic substrates for pelagic bacteria are derived from dissolved organic carbon (DOC) in the water column that originates either from primary production from within the lake itself (autochthonous), or import of organic matter from the terrestrial watershed (allochthonous production). This thesis addresses the utilization of allochthonous versus autochthonous carbon (C) sources by lake bacteriopl
