A New Multi-Objective Optimisation Technique Applied to a Vehicle Drive Train Simulation

Daniel Favrat, Adam Molyneaux, Geoffrey Basil Leyland

This paper presents a methodology for optimisation of vehicle drivetrain configuration and their design with respect to multiple parameters. Some preliminary results from such optimisations are presented. Multi-objective optimisation algorithms have been d ...

Video Object Extraction based on Adaptive Background and Statistical Change Detection

Touradj Ebrahimi

This paper introduces a system for video object extraction useful for general applications where foreground objects move within a slow changing background. Surveillance of indoor and outdoor sequences is a typical example. The originality of the approach r ...

On-line stoichiometry and identification of metabolic state under dynamic process conditions

Urs von Stockar, Ian William Marison, Christoph Herwig

A method for the online calcn. of conversion rates and yield coeffs. under dynamic process conditions was developed. The method is based on cumulated mass balances using a moving av. method. Elemental balances were used to test the measured cumulated quant ...

Doping-induced change of optical properties in underdoped cuprate superconductors

Giorgio Margaritondo, László Forró, Helmuth Berger

We report on the ab-plane optical reflectance measurements of single crystals of Y-doped Bi2Sr2CaCu2O8+delta and Pr-doped YBa2Cu3O7-delta over a wide frequency range from 80 to 40 000 cm(-1) (10 meV-5 eV) and at temperatures between 20 and :300 K. Y and Pr ...

Ozone flux measurements in the troposphere with a shot per shot DIAL instrument operated in the UV spectral region during the MEDCAPHOT campaign

Hubert van den Bergh, Bertrand Calpini, Alain Clappier

The first combined reconstruction of range-resolved wind velocities and O3 concns. is presented from the anal. of a single DIAL data set analyzed with a correlation method to det. wind speeds. The system can be used for the measurement of a unique componen ...

Speaker identification by lipreading

This paper describes a new approach for speaker identification based on lipreading. Visual features are extracted from image sequences of the talking face and consist of shape parameters which describe the lip boundary and intensity parameters which descri ...

Speachreading using shape and intensity information

We describe a speechreading system that uses both, shape information from the lip contours and intensity information from the mouth area. Shape information is obtained by tracking and parameterising the inner and outer lip boundary in an image sequence. In ...

Superconducting Gap and Order-Parameter in Bi2sr2cacu2o8+X

Giorgio Margaritondo

Using angle-resolved photoemission, we observed a nonzero superconducting gap and the presence of a superconducting condensate along all three major symmetry directions. We find that the gap is highly anisotropic, with a gap as small as 1-2 meV along GAMMA ...

Export of mRNA from microinjected nuclei of Xenopus laevis oocytes

Lukas Kühn

Export of mRNA from the nucleus to the cytoplasm was studied in mature Xenopus laevis oocytes. In vitro transcribed, capped 32P-labeled mRNA was microinjected into nuclei, and its appearance in the cytoplasm measured by counting radioactivity or by RNA ext ...

DSR 15 T, a system for the automatic derivation of a digital terrain model

Roger Hersch

The Institute of Photogrammetry has developed a peripheral system for the automatic derivation of digital terrain models for the analytical plotter Kern DSR 15; this project is carried out in close collaboration with Leica AG. The principal component of th ...
