In the present work the influence of a LuGre type friction law [cf. to C. Canudas de Wit, H. Olsson, K.J. Aström, P. Lischinsky, A new model for control of systems with friction, IEEE Transactions on Automatic Control 40 (1995) 419] on the fundamental mechanisms resulting in linear instability of steady sliding in point contacts is investigated. Both a velocity-dependent kinetic friction coeffi...

The branching fractions for !ee, , and hh are measured using data collected with the, where the rst errors are statistical, the second systematic, and h refers either to a charged or K. Also measured is the tau mass, m=(1778.21.4) MeV. Lepton universality is aarmed by the resulting relative branching fractions (B/Be=0.97770.00630.0087, B h /Be=0.64840.00410.0060) and the charged-current gauge c...

Propp and Wilson (1996) described a protocol, called coupling from the past, for exact sampling from a target distribution using a coupled Markov chain Monte Carlo algorithm. In this paper we discuss the implementation of coupling from the past for samplers on a continuous state space; our ultimate objective is Bayesian MCMC with guaranteed convergence. We make some progress towards this object...

Collaborative systems that automate the sharing of programmer-defined user interfaces offer limited coupling flexibility, typically forcing all users of an application to share all aspects of the user interfaces. Those that automatically support high coupling flexibility are tied to a narrow set of predefined user-interfaces. We have developed a framework that provides high-level and flexible c...

We propose an efficient optical coupler between a submicrometer-sized silicon waveguide on a silicon photonic chip and a multi-micrometer wide polymer waveguide on an optical printed circuit board for interchip optical networks. We show low coupling loss <0.4 dB with high lateral and angular tolerance to misalignment so that coupling can be done by automatic pick-and-place equipments with high ...

We provide a dynamic systems interpretation of the coupling of internal states involved in speed-dependent automatic zooming, and test our implementation on a text browser on a Pocket PC instrumented with an accelerometer. The dynamic systems approach to the design of such continuous interaction interfaces allows the incorporation of analytical tools and constructive techniques from manual and ...

Automatic dictation systems (ADS) are nowadays powerful and reliable. However, some Inadequacies of the underlying models still cause errors. In this paper, we are essential ly interested in the language model implemented In the linguistic component, and we leave aside the acoustic module. More precisely, we aim at Improving this linguistic model by coupling the ADS with a syntactic parser, abl...
