Selected AbstractsCharring rates and temperature profiles of wood sectionsFIRE AND MATERIALS, Issue 2 2003Andrea Frangi Abstract A research project was carried out at the Swiss Federal Institute of Technology (ETH) to study the fire behaviour of hollow core timber slabs and timber-concrete composite slabs. This paper describes the main results of the basic fire behaviour of timber measured in the study. The first part of the analysis looks at the charring rate of timber. In the second part a new calculation model for the temperature development in wood members exposed to the standard ISO-fire is presented and compared with the fire test results.

Rötheli This article relates to the view expressed by Pigou and Keynes that whatever factors affect the demand for goods it is ultimately producers' expectations and plans that determine the level of output. We build on this notion in order to address the question how changes in monetary policy affect output in Switzerland. For this purpose we study data on expected and actual output collected by the business cycle research center(KOF) at the Federal Institute of Technology (ETH) in Zürich. The econometric analysis documents that monetary affect output only by their impact on expectations of entrepreneurs. This finding contradicts the new classical view of the propagation of monetary shocks.

[source] Zerstörungsfreie Ortung von Fehlstellen und Inhomogenitäten in Bauteilen mit der Impuls-ThermografieBAUTECHNIK, Issue 10 2004Ralf Arndt Dipl.-Ing. Im Rahmen eines von der Deutschen Forschungsgemeinschaft geförderten Forschungsvorhabens wird von der Bundesanstalt für Materialforschung und -prüfung (BAM) und der Technischen Universität Berlin (TUB) die Anwendung der Impuls-Thermografie zur zerstörungsfreien Prüfung von Bauteilen und Bauwerken weiterentwickelt. Zu diesem Zweck werden Messungen zu verschiedenen baupraktischen Fragestellungen durchgeführt. Die Bauteiloberflächen werden mit einer Wärmequelle, die dem Prüfproblem angepaßt ist, erwärmt. Der daran anschließende Abkühlungsvorgang wird mit einer Infrarotkamera beobachtet und aufgenommen. Die anschließende Auswertung der gespeicherten Daten wird im Zeitbereich mittels numerischer Verfahren und im Frequenzbereich mittels Puls-Phasen-Thermografie durchgeführt. Die Puls-Phasen-Thermografie führt insbesondere zu einer praxisrelevanten Reduzierung des Störeinflusses von Oberflächeninhomogenitäten und ungleichmäßiger Erwärmung. Non-destructive detection of voids and inhomogeneities in building structures using impulse thermography. In the frame of a research project funded by the "Deutsche Forschungsgemeinschaft" the application of impulse thermography for the non-destructive testing of building components and buildings is further developed by the Federal Institute for Material Research and Testing (BAM) and the Technical University of Berlin (TUB). To this aim measurements to several practical problems of civil engineering were carried out. The inspected specimen is pulse heated according to the problem. The following cooling down process is recorded with an infrared camera. The transient behaviour is afterwards analysed by numerical methods in the time domain and by means of Pulse-Phase-Thermography in the frequency domain. Pulse-Phase-Thermography in particular reduces the influence of inhomogeneous surfaces and non-uniform heating on thermographic measurements.

[source] The Creation of a Vocational Sector in Swiss Higher Education: balancing trends of system differentiation and integrationEUROPEAN JOURNAL OF EDUCATION, Issue 4 2003Juan-Francisco Perellon The article discusses the establishment of a vocational sector in Swiss higher education as a complement to the existing two-tier system of cantonal Universities and federal Institutes of technology. The origins of this new player, its missions and organisational features are discussed. This overall discussion is placed into the context of changing landscape of Swiss higher education policy characterised by increasing pressures for geographical reorganisation of the higher education sector under the auspices of a more direct role of the federal government. The article makes two points. First, it argues that the creation of a vocational sector in Swiss higher education combines two contradictory trends. On the one hand, this new sector tends to provide differentiation at the system level, through the creation of a new, more marked-oriented sector of higher education. On the other hand, system differentiation at the system level is threatened by increased demands for greater inter-institutional cooperation and system integration, emanating principally from the federal level. Second, the article also argues that the distinction between ,academic/scientific' vs. ,vocational/professional' education generally referred to when studying the emergence of non-university sectors in higher education, is not pertinent for the analysis of the Swiss case. Two reasons are brought forward to sustain this argument. First, this distinction reinforces an artificial binary divide, no longer relevant to assess the evolution of higher education institutions placed in a context of academic and vocational drifts. Second, the ,academic' vs. ,professional' opposition does not take into consideration the political organisation of the country and how this impacts on policy making in higher education; a crucial element in the Swiss context.
