Both energy security and the demand for energy, particularly from renewable energy sources, as principle drivers, call for the investigation of renewable energy potential in Poland. The city of Zabrze, located in the Upper Silesia province and urban zone of Katowice, dedicates continuous efforts to the improvement of its waste management against the background of European Union Directives requirin
DBK (Dansk Bygge Klassifikation) er blevet udarbejdet i årene 2005-2006 som en del af den Danske Stats projekt om digitalt udbud, projektering og aflevering i den danske byggesektor, der samlet kaldes Det Digitale Byggeri. Siden fremkomsten har enkelte firmaer anvendt DBK i praksis, andre har brugt dele af systemet, mens andre igen har været afventende og ikke taget DBK i anvendelse. På baggrund a
Ultra-short X-ray pulses are generated by focusing 150 fs laser pulses with an energy of 200 mJ onto metal targets. Focal intensities are expected to reach 1018 WI cm2• An efficient X-ray source has been developed. This X-ray source has been characterised, with an emphasis on photon energies above 10 keV. Measurements of the spectral distribution of X-rays, the overall X-ray yield and the spatial
The subject of the thesis is intericonicity, i.e. the relations between iconic signs. Hypothetically we only have a tacit knowledge of interikonicity, and the aim of the thesis is to establish a theory about it, grounded in hermeneutics and semiotics. According to this Theory of Intericonicity all representations, all iconic signs, are fascinated, rhetorical transformations of models. Paraphrase a
The number of weblogs has increased exponentially since several weblog service providers released free and easy-to-use software in late 1999. This enabled people with a computer, Internet access and a desire to present themselves and their daily lives, and/or their political views, tech news, knitting projects for a possible audience to create and keep a blog. Yet, why do people read blogs, and wh
Popular Abstract in Swedish Ljusspridning och absorption i biologisk vävnad - modeller och mätningar Visionerna är stora i medicingruppen på avdelningen för atomfysik, LTH, nämligen att utveckla nya metoder för förfinad diagnostik och selektiv behandling av cancer, hjärt- och kärlsjukdomar med hjälp av laserljus. Möjligheten till att med ljus detektera och karakterisera sjuk vävnad, exempelvis tIn this work a number of theoretical models, describing light propagation in matter, have been applied to and developed for the examination of tissue. The aim was to model the light scattering and absorption in tissue in order to improve the understanding of underlying mechanisms of laser-based diagnostics and treatment modalities utilised for cancer and cardiovascular diseases. The models studied
Controlling an induction machine has been a difficult task since its invention, especially at low speed operation and during highly dynamic regimes, where the required torque/speed changes constantly. This paper aims to present the validation and implementation of a deadbeat direct torque and flux control scheme (DB-DTFC) for induction machines on a multilevel platform consisting on an FPGA, a rea
