Competition in liberalized energy markets and increasing environmental concerns call for industrial power generation that is both cost effective and environmentally friendly. This is true for both the operation of existing as well as the development of new ...
We examine the apparent disorder which seems to characterize the spatial structure of soil moisture by analyzing large-scale experimental data. Specifically, we address the statistical structure of soil moisture fields under different scales of observation ...
Reflection, transmission and loss filters based on fiber Bragg gratings are key components in future wavelength division multiplexing telecommunication networks. A shift of the Bragg wavelength, λg, can be achieved by applying a strain or heating th ...
The integration of PV modules into platform canopies has several advantages: - Very large areas are available and just waiting to be used - These areas are nationally owned - There is maintenance personnel on-site - The areas are exposed to the view of num ...
The research and development of a durable, elec. rechargeable Zn/O2 battery in the PSI-BEW project at the Paul Scherrer Institute is described in a review with many refs. The first phase included the development of La0.6Ca0.4CoO3-activated bifunctional O2 ...
Geometry recovery of a turbine runner can be of prime importance in at least two cases: upgrading of an old power plant and field repair of a runner. Considering the importance of the field geometry recovery, we have decided to compare three methods of mea ...

An estimate of the sorptivity that requires only the knowledge of simple integrals of the soil-water diffusivity weighted by a power of the water content is present. The result is checked systematically for diffusivity functions with very different behavio ...
The present work is part of a general research program conducted by the Machine-Tools and Automata Laboratory of the Federal Institute of Technology in Lausanne on "Synthetic Intelligence". The final goal is to automatize design using computers in mechanic ...
Security analysis of large power systems requires the evaluation of a large number of possible contingencies of the power system. For large power systems, even if only single component contingencies are considered or if fast methods are employed, full AC a ...
An all-fiber tunable filter device that uses a resistive fiber coating to directly heat an intra-core Bragg grating is presented. Bragg gratings were fabricated in a hydrogen-loaded standard telecommunication fiber by a KrF excimer laser with a fluence of ...
