Deadlock problems of zone-control uni-directional automated guided vehicle systems (AGVS) are discussed in this paper. A directed graph is de® ned to model the vehicle ¯ ows, to identify distinct vehicle ¯ ows, to represent ...

The local Hurst exponent, a measure employed to detect the presence of dependence in a time series, may also be used to investigate the source of intra day variation observed in the returns in foreign exchange markets. ...

In this article we investigate the design of scoring schemes for surveys using the block total response method. This method was first proposed by Raghavarao and Federer (1979) to provide accurate estimates of the base ...

In this paper a numerical procedure is developed for the material-nonlinear analysis of composite beams composed of two Euler-Bernoulli beams juxtaposed with a deformable shear connection. In the displacement-based finite ...

A three-dimensional dynamic interaction model is developed for a LIM (linear induction motor) train and elevated bridge system, which is composed of a LIM-driven vehicle submodel and a finite element bridge submodel. Each ...

Within a continuous-time framework, this paper proposes a stochastic heterogeneous agent model (HAM) of financial markets with time delays to unify various moving average rules used in discrete-time HAMs. The time delay ...

In this study, the two-machine bicriteria flowshop scheduling problem is addressed. The objective is to minimize a weighted sum of total flowtime and makespan. Different branch-and-bound algorithms have already appeared ...

This paper addresses the mechanics of the flexural-torsional buckling instability of pin-ended elastic circular arches, which are acted upon by a hydrostatic loading. This loading arrangement differs from the gravity-based ...

The aim of this paper is to document some empirical facts related to log-returns of diversified workld stock indices when these are denominated in different currencies. Motivated by eaarlier results we jave obtained the ...
