Advanced Power Plant Design Methodology using Process Integration and Multi-Objective Thermo-Economic Optimisation

François Maréchal, Daniel Favrat, Raffaele Bolliger

Thermo-economic modelling techniques are well known techniques to optimise power plant designs. These methods are usually based on the definition of a superstructure that includes the major options of the design. If this approach has proved to be appropria ...

Mechanical spectroscopy of Al-Cu-Fe quasicrystalline coatings

Robert Schaller, Nadine Baluc

Since the bulk Al-Cu-Fe quasicrystals are extremely brittle below 700 K, a quasicrystalline coating deposited on a steel substrate by thermal spraying was used for mechanical spectroscopy measurements at temperatures in the range of 300-800 K. The internal ...

Low-Power Excitation of Gyrotron-Type Modes in a Cylindrical Wave-Guide Using Quasi-Optical Techniques

Minh Quang Tran

Experimental results of low-power excitation of a 118 GHz TE(22,6) rotating mode are presented. A rectangular waveguide is converted to a TE(22,6) circular waveguide mode using quasi-optical techniques. A good conversion efficiency is measured and the expe ...

Modern power conversion for complementary energy storage

Alfred Rufer

Similar to the classical solution of hydraulic pump-turbine plant, new means for accumulation of eletrical energy are given for lower but respectable quantities by the so called BESS (Battery Energy Storage System) and SMES (Super conducting Magnet Energy ...

Analysis of Kalina Cycle Designs with Modifications Including a Distillation Column.

It has been shown in a number of studies that the Kalina cycle can have considerably higher efficiencies than the Rankine cycle. An especially advantageous application is as a bottoming cycle to a gas turbine. In this paper a gas turbine topping cycle has ...

Thermal-Conversion of N-Type Gaas-Si to P-Type in Excess Arsenic Vapor

Franz-Karl Reinhart, Jean-Daniel Ganière

Annealing in excess arsenic vapor at 650-degrees-C introduces thermal conversion of n-type Si-doped GaAs samples (n = 1.3 X 10(18) cm-3) into p type. The observations are made by current-voltage and electron-beam induced current measurements. The donor con ...

Analysis of the vertical displacement of energy pile groups

Lyesse Laloui, Alessandro Francesco Rotta Loria, Aurélien Vadrot

Over the last fifty years, the interaction factor method has been widely used to address the vertical displacement and the increased deformation of conventional pile groups subjected to mechanical loads when group effects and interactions occur among the p ...
