Improving the quality of education is the goal of all pedagogical research. By using student surveys and course evaluations problem areas can be identified in most courses offered by universities. In this paper we perform a large-scale student survey in order to find the causes of, and remedies to, a widespread student dissonance in a mandatory course with over 100 students at Lund University. Our

I denna artikel används Kenneth Burkes teori om estetisk och retorisk form, från Counter-Statement (först publiserad 1931), för att analysera hur stjärnkocken Mathias Dahlgren kreear en gourmetmåltid. Samtidigt framgår att Burkes teori förmår att hantera problem som dominerande teorier om tjänstekvalitet har problem med.

The ATLAS Collaboration at CERN is preparing for the data taking and analysis at the LHC that will start in 2007. Therefore, a series of Data Challenges was started in 2002 whose goals are the validation of the Computing Model, of the complete software suite, of the data model, and to ensure the correctness of the technical choices to be made for the final offline computing environment. A major fe

Flame flashback from the combustion chamber to the premixing section is a major operability issue when using high H-2 content fuels in lean premixed combustors. Depending on the flow-field in the combustor, flashback can be triggered by different mechanisms. In this work, three flashback mechanisms of H-2/CH4 mixtures were visualized in an atmospheric variable swirl burner using high speed OH chem

In this paper we suggest an improved algorithm for estimation of parameters detailing Gaussian functions and expand it to handle linear combinations of Gaussian functions. Components in the signal are first detected in the spectrogram, which is calculated using a Gaussian window function. Scaled reassignment is then performed using a set of candidate scaling factors and the local Renyi entropy is

Popular Abstract in Swedish Bortglömda, stulna eller på andra sätt borttappade radioaktiva strålkällor som kan anses vara farliga för allmänheten kallas herrelösa strålkällor. Denna avhandling handlar om metoder för att hitta herrelösa strålkällor som emitterar s.k. gammastrålning, bestående av ljuspartiklar med mycket hög energi. Gammastrålning har god förmåga att penetrera materia och kan därförHazardous radioactive sources out of regulatory control are referred to as orphan sources. Focussing on gamma-emitting orphan sources, this thesis describes methods that can be used in mobile gamma-ray spectrometry to perform real-time discrimination between an actual source signal and the signal due to the natural radiation background. Two categories of methods for orphan source detection are pre

The World Wide Web is undoubtedly very successful. Despite that, limitations have been recognized. The basic limiting factor is that the Web handles document for humans to read but not data and information for computers to read. The remedy of this is to provide the Web with semantics: the Semantic Web. While I agree that there is a need for another organization in which it is easier to find the in

I denna essä analyseras rätten till skilsmässa vid hustrumisshandel i 1800-talets politiska debatt och den praktiska hanteringen av hustrumisshandel i kyrkliga och världsliga rättsliga instanser.
