The dominating part of electron injection from the transition metal complex Ru(dcbpy)2(NCS)2 into a titanium dioxide nanocrystalline film proceeds extremely rapidly from the initially populated, vibronically nonthermalized, singlet excited state of the molecule. Ultrafast transient absorption measurements with laser pulses of the order of ~30 fs have been performed

Popular Abstract in Swedish Konventionella neuropsykologiska test, och begåvningstest, tar sällan hänsyn till att begåvningen "filtreras" genom individens personlighet vid utförandet av uppgifterna. Två lika begåvade personer (dvs med samma IQ) kan utföra samma test på helt olika sätt beroende på t.ex att den ena är impulsiv och snabb och den andra eftertänksam och försiktig. Detta medför skillnad"Personality determines very largely the use a person makes of his intellectual gifts" (Eysenck, 1988). Computerization of neuropsychological tests has made possible a detailed analysis of both quantitative and qualitative aspects of a person´s test performance. Factor analyses of test data generally bring out two main factors of performance: speed and accuracy, representing both the intellectual

The extraction of semantic propositions has proven instrumental in applications like IBM Watson (Ferrucci, 2012) and in Google’s knowledge graph (Singhal, 2012). One of the core components of IBM Watson is the PRISMATIC knowledge base consisting of one billion propositions extracted from the English version of Wikipedia and the New York Times (Fan et al., 2010). However, extracting the proposition

This thesis addresses micromechanical modeling of materials using computational homogenization. On this topic, theoretical and computational issues are discussed, and numerical investigations of different material systems are performed. The material systems considered are; metal matrix composites, metal sheets with stiff inclusions, metal sheets containing voids, sand with inclusions of gravel and

Perikles is usually seen as a great statesman and clever leader of the Athenians. In the mid fifth century BC, he seems however to have been in serious political trouble and may well have been in danger of losing the struggle for power and of being ostracised. The fact that his Incentives changed considerably at this point in time is ignored in traditional historical accounts. In contrast, we see

Popular Abstract in Swedish Ny innovativ processdesign har resulterat i två processer som kan göra tillverkningen av förnyelsebara plaster och bränslen konkurrenskraftiga mot dagens fossila alternativ. Den nya designen har gjort vissa processteg upp mot 40 gånger så effektiva som med dagens teknik. Vikten av att ställa om dagens samhälle, som till stor del är beroende av fossila resurser, till eIt is important to replace fossil resources such as oil, coal and natural gas with renewable raw materials for the production of materials and fuels in order to reduce environmental impact. Furthermore, these raw materials should preferably be residues, e.g. agricultural or forest residues, in order not to compete with the production of human food and animal feed.

Newton-Raphson and Goldschmidt algorithms can be sped up by using variable latency hardware architectures for rounding division, square root and their reciprocals. A new approach based on a rounding method with remainder estimate calculated concurrently with the algorithm was proposed in [5]. This paper presents an study of the hardware implementation of this approach and shows that does not suppo

Developments in body theory have had a strong impact on archaeology in recent years, but the concept of the body has tended to remain abstract. The term “body” is often used as a synonym for self or person, and the remains of bodies and body parts have often been approached theoretically as signs or symbols. While this has emphasized the importance of the body as a cultural construct and a social

We consider construction and realization aspects of encoders and decoders for braided block codes (BBCs), which are a powerful class of iteratively decodable codes. An efficient encoder is proposed as well as a pipeline decoder realization. Also, upper and lower bounds on the free distance of BBCs are derived.
