Studium und berufliche Qualifikationsanforderungen
(2004)Im Jahr 2003 wurden die AbsolventInnen der Abschlussjahrgänge 1993 bis 2001 des Studiengangs Forstwissenschaften (FOWI) sowie der Abschlussjahrgänge 1996, 1997 und 2001 des Studiengangs Umweltnaturwissenschaften (UMNW) befragt. Die Analyse zeigte eine grosse Ähnlichkeit zwischen den Antworten der FOWI und UMNW AbsolventInnen bezüglich ihrer aktuellen beruflichen Situation (vgl. Übersicht in Abschnitt 3.1.13). Die ...Report -
Design of a high efficiency pulsed slow positron beam for measurements of porous silicon and polymer films
(2004)LAPP-EXP-2004.08; INR-HEP-2004.31This document presents the design of a pulsed slow positron beam to study porous silicon and polymer films. Slow positrons are produced with a conven- tional technique using a ^22Na source and a tungsten film moderator. The goal of the proposed design is to reach a pulse duration of 0.3 ns FWHM at the target. The scheme of the beam includes two choppers and two bunchers. The distinctive features of the proposed design lie ...Report -
Analysis of a dual-primal FETI algorithm for edge elements on boundary layer meshes in two dimensions
(2004)Research ReportFETI methods are among the most heavily tested domain decomposition methods. The purpose of this thesis is to analyze a dual-primal FETI method for edge element approximations in two dimensions on geometrically refined meshes. These meshes are highly anisotropic, where the aspect ratio grows exponentially with the polynomial degree. The primal constraints are here averages over subdomain edges. We prove that the condition ...Report -
On a conjectured increasing series
(2004)Research ReportThe rate of total heat loss of two bodies maintained at constant temperature in a homogeneous conducting medium of low temperature is a function of the distance between the two bodies. Assuming spherical bodies with equal temperatures, this function has been explicitly computed in [4] and its monotonic increase has been verified numerically. In this note we give a rigorous completely elementary proof of this fact, and thus ...Report -
