Abstract in UndeterminedA comparison is made of battery charger topologies for electric vehicles. The chargers are all off-board, and capable of active power line conditioning and bi-directional power flow to compensate local utilities during peak power loads. The active power line conditioning capability is important, since an increase of battery chargers based on ordinary diode rectifiers would

This contribution probes the notion of non-nationalist civic identity in the context of the EU, and looks at the media's potential role in developing it.

"Denna bok behandlar alla typer av byggnadsmaterial. Materialen behandlas kapitelvis där deras uppbyggnad, tillverkning och egenskaper beskrivs. Syftet är att skapa en grundläggande förståelse för materialens förtjänster och begränsningar. Denna kunskap kan användas vid t.ex. val av material i allmänhet, bedömning av egenskaper i samband med återvinning av material och materialval i samband med s.

Praxisbegreppet, sedan existentialismen och marxismens stora dagar, har lämnat upplysningens säkra marker för att istället växa inom en så kallad postmodern världsåskådningsram. Denna åskådningsram kräver ett närmande som är månskiftande, en eklektisk reflexion som i slutändan innebär en dekonstruktion av postmodernismen.

Följande texter är tidigare publicerade som blogginlägg på Cybernormer.se samt digitalsociety.se och kretsar kring arbetslivets förändring i en digital kontext. Tillitsbegreppet är centralt här och texterna diskuterar exempelvis kontroll och övervakning - eller "employee monitoring" - kontra ökade frihetsgrader för anställda att styra över sina arbetstider.

A prediction of structural behaviour and fire resistance is presented for some different types of concrete members. This is made by use of two computer programs TASEF-2 and CONFIRE for thermal and structural response, respectively. Fire resistance times predicted by CONFIRE for different failure criteria and those obtained from different design recommendations are compared for a simply supported p

iological effects of radio frequency electromagnetic fields (EMF) on the blood-brain barrier (BBB) have been studied in Fischer 344 rats of both sexes. The rats were not anaesthetised during the exposure. All animals were sacrificed by perfusion–fixation of the brains under chloralhydrate anaesthesia after the exposure. The brains were perfused with saline for 3–4 minutes, and thereafter perfusion

In Statoil, understanding and managing risk is today considered a core value. This principle has been duly integrated in the organization, and is inscribed in steering documents as well as in a booklet handed out to all employees, describing core values, corporate governance, the operating model and corporate policies. The company has developed a sophisticated approach to ERM that centers on the p

A critical assessment of a widely applied approach for the prediction of temperature-insensitive absorption lines is presented. This approach was found to suffer from significant shortcomings.

In this paper the problems of organization and representation of concept knowledge are addressed from an autonomous agent perspective. The first part of the paper discusses the question of why an autonomous agent needs concepts at all and what other uses it can make of them. After the necessary and/or desirable functions of concepts have been identified, previous attempts to represent concepts are

Olsson and his collaborators have proposed an extension of Belief Revision Theory where an epistemic state is modeled as a triple S=⟨K,E,A⟩ , where A is a research agenda, i.e. a set of research questions. Contraction and expansion apply to states, and affect the agenda. We propose an alternative characterization of the problem of agenda updating, where research questions are viewed as blueprints

Popular Abstract in Swedish En av tre svenskar drabbas av cancer. Hälften av de som behandlas för sin cancer får strålbehandling som en del av sin behandling. Teknikutvecklingen gör att strålbehandling kan levereras på mer och mer avancerade sätt. Det är dock svårt att veta vilka patienter som verkligen gynnas av behandling med en avancerad teknik och i så fall med vilken typ av avancerad teknik. Radiotherapy is one of the major tools for treating cancer. Through research and technical development radiotherapy is becoming more advanced with new treatment techniques emerging. In the work presented in this thesis, well-known methods have been used, or modified for use, and new methods have been introduced in order to optimise the clinical use of an advanced radiotherapy treatment technique,
