Abstract: Pulse microelectrochemical machining (ECM) by bipolar current is a method allowing the manufacturing of microholes and micropatterns. In many cases, microholes with parallel walls and accurate ...

Abstract: The divergence of initially close trajectories sets the limit of dynamical predictability for infinitesimally small errors; its global average measure is given by the first Liapunov exponent. It is shown, within the framework ...

Abstract: The problem of predictability in relation to the existence of multiple flow regimes is examined for the atmosphere on the basis of observations. The existence of multiple-flow regimes and the dynamics of transitions between ...

Abstract: Numerical integration experiments with a primitive equation model in isentropic coordinates are performed to investigate the influence of orography on cyclone formation. Results obtained in the presence of an isolated ...

Abstract: The purpose of this paper is to examine mediation for public construction contracts under the Government Procurement Act (GPA) in Taiwan. The World Trade Organization Committee on Government Procurement, on December 9, ...

Abstract: A post-buckling analysis of a constant or variable length spatial elastica constrained by a cylindrical wall is performed for a first time by adopting an optimal control methodology. Its application in a constrained buckling ...

Abstract: The paper presents the identification process of inelastic (viscoplastic) properties for two aluminum alloys at a temperature of 120°C. The material parameters are calculated on the basis of uniaxial tension tests. Twelve ...
