This paper presents a numerical study of the 3D ow around a cylinder which was de ned as a benchmark problem for the steady state Navier–Stokes equations within the DFG high-priority research program ow simulation with high-performance computers by Sch afer and Turek (Vol. 52, Vieweg: Braunschweig, 1996). The rst part of the study is a comparison of several nite element discretizations with res...

The treatment of stream lines path lines and streak lines is a powerful method for visualizing the behavior of unsteady i e time dependent ow elds Although a closed parametric form of these lines does not exist we show how to compute their curvatures The visualiza tion of the curvatures of these curves shows several aspects of the ow such as location and movement of turbulent areas The techniqu...

In controlling manipulators interacting with the external environment, an important issue is the choice and construction of the Cartesian level control system. To eeec-tively control the constrained manipulators, a knowledge of the resulting compliance of the system is required. In this paper a systematic analysis of the Cartesian stii-ness and compliance matrices, which at full extent has not ...

Background: Aflatoxins (AFs) are the most prevalent carcinogenic mycotoxins, produced mainly by Aspergillus flavus and A. parasiticus. The general purpose of the present study was to use Dehydroacetic Acid (DHA) and Ozonated Water (OW) to control A. flavus growth and accumulation of Aflatoxin B1 (AFB1) in Iranian pistachios. Methods: Three treatment pistachio groups were separately immersed ...

We address several aspects related to managing re-entrant lines in an uniied manner { capacity allocation, inventory management and production control { in a set of three papers. Our approach to study these systems is through simulation based optimization. Simulation ooers the exibility to model the complexities adequately while the gradient computation (via Innnitesimal Perturbation Analysis) ...

In this paper we describe a problem that we de ne as the Budget-Constrained Minimum Cost Flow (BCMCF) problem. The BCMCF problem is a natural extension of the well-known Minimum Cost Flow (MCF) [2] problem, with a xed cost related to the use of arcs and a budget constraint. Network ow problems often become hard when extra constraints are added. Ahuja and Orlin [1] discuss the constrained maximu...

This paper continues our study on the management of multi-product, capacitated re-entrant lines. Based on the theoretical framework developed in 2], we discuss some insights obtained by a simulation study. We are interested in understanding the performance of implementable capacity management schemes (No-sharing, Partial Sharing and Total Sharing) and production rules (Linear Scaling, Equalize ...

In the title compound, C15H23N3O3S·H2O, the piperidine ring has a chair conformation. In the crystal, the sulfonamide mol-ecules are linked by N-H⋯O hydrogen bonds, forming a layer parallel to (10-1). The layers are inter-connected via N-H⋯Ow, Ow-H⋯N and Ow-H⋯O (w = water) hydrogen bonds, forming a three-dimensional network.

Discrete event simulation systems (DESS) are widely used in many diverse areas such as computer-communication networks, exible manufacturing systems, project evaluation and review techniques (PERT), and ow networks. Because of their complexity , such systems are typically analyzed via Monte Carlo simulation methods. This paper deals with optimization of complex computer simulation models involv...
