The objective of this paper is to introduce a new direct method for neutronic calculations. This method, called Direct Discrete Method (DDM), is simpler than the Neutron Transport Equation and more compatible with the ...

In this paper, a genetic algorithm is presented for the simultaneous layout and pipe size optimization of water distribution networks and its e ciency is evaluated and compared using di erent selection mechanisms. An ...

Application of the base-isolation systems, as a means to limit the seismic-induced response of structures, has attracted the attention of many engineers and researchers. Due to their importance, the Uniform Building Code ...

In this paper, the modeling and impedance-control of a one link exible robot is presented. The concept of impedance control of exible link robots is rather new and is being addressed for the rst time. The control ...

In this paper, the Markov models, eigenvectors and eigenvalue concepts are used to propose a methodology for analyzing the transient reliability of a system with identical components and identical repairmen. The components ...

This paper describes an attempt to develop congestion indices for a developing country with a limited sampling. Speed and ow rate information was collected from urban highway tra c ow videotaping in Iran. Video display ...

In this investigation, a computational model has been developed, including heat transfer and the e ects of the resistance of a metal-mold interface and pressure, for simulation of the solidi cation process. Simulation ...

In this paper, rst, the equations of motion for a rectangular isotropic plate have been derived. This derivation is based on the Von Karmann theory and the e ects of shear deformation have been considered. Introducing ...
