The design of high performance instruments often involves the attenuation of poorly damped resonant modes. Current design practices typically rely on informed trial and error based modifications to improve dynamic performance. In this article, a multi-material topology optimization approach is presented as a systematic methodology to develop...

metallic tie-rods are installed under all naves to support a portion of the lateral thrust exerted by vaults and arches. After the recent failure of one tie-rod, an extensive research program was carried out to characterize the metallic material and to evaluate the axial forces and the tensile stresses of the tie-rods through dynamic testing and...

Modal properties of high rise buildings are mostly derived from measurements on existing buildings under dynamic random wind loading. Measured accelerometer signals are translated into values for the natural frequency and damping. In order to obtain reliable values for the modal properties, the distillation of these parameters from the measured...

Usually the design of the monitoring system is based on the relation between the monitoring effort and the uncertainty of the information. Often the estimation error standard deviation is used as a criterion for the design. Despite the fact that, for scientists, the standard deviation as a measure of uncertainty is a logical criterion, water...

In this paper an alternative approach for the design of open-ended waveguide array antennas is presented. The approach is based on microwave filter concepts. The exploitation of this alternative viewpoint has been made possible by the availability of a very efficient computer-aided design (CAD) tool which is based on a full-wave modal analysis...
