The second preclinical year of the medical curriculum at the Medical Faculty of the University of Lausanne in Switzerland includes nine multidisciplinary organ-system-oriented modules consisting of lectures and problem-based-learning tutorials. This study reports the experience accumulated with the evaluation of lectures during the academic years 1998–1999 and 1999–2000. The ratings of the different modules were highly variable, indicating the ability of students to have a critical view on the teaching and the teachers. There was a close to very close correlation between the ratings obtained during the two study years. The high discriminative capacity of students in evaluating the teaching and the teachers was also supported by their critical point of view expressed in free comments. Our observations stress therefore the reliability of teaching evaluations systematically performed by medical students. 相似文献

The reduction of the study of continuous dynamical systems to the study of point mappings was first effected by Poincaré, and later more generally by Birkhoff, in the conservative case. However, the analytical expressions of these mappings are, in most cases, rather complicated or even unknown. This paper deals with the construction of area- preserving polynomial point mappings in the plane osculating the actual one (also area preserving) to a certain degree. These mappings can be used for an approximate study of the behaviour of solutions in a neighbourhood of the origin taken as a fixed point. To illustrate this approach, some numerical examples are given. 相似文献

Fault detection and diagnosis are important issues in process engineering. Hence, considerable interest is growing in this field from industrial practitioners as well as academic researchers, as opposed to 30 years ago. This paper focusses on a model-based approach for fault detection. This approach is based on Finite Memory Observers (FMO), properties of this observer are presented in the first part of our work (Graton et al., 2014 [1]), the main results of this paper are recalled at the beginning of this paper and constitute the basis of this second part. Properties of the Finite Memory Observer (FMO) are studied from a global point of view for the class of linear time-varying (LTV) systems with stochastic noises. FMO performances take their framework from the study of their properties, and from the study of their influences on diagnosis results. Fundamentally, the generation of residuals is essential in a diagnosis procedure. In Graton et al. (2014) [1], the design for the finite memory observer is shown, the determination of its optimal window length is solved, and the generation of residuals for diagnosis is completed. This paper is the second part of this work and is devoted to the study of the observer and residual sensitivity towards model parameter variations and noises. 相似文献
