This paper describes predictive load balancing schemes designed for use with parallel adaptive finite element methods. We provide an overview of data structures suitable for distributed storage of finite element mesh data as well as software designed for mesh adaptation and load balancing. During the course of a parallel computation, processor load imbalances are introduced at adaptive enrichme...

The parametric maximum flow problem is an extension of the classical maximum flow problem in which the capacities of certain arcs are not fixed but are functions of a single parameter. Gallo et al. [6] showed that certain versions of the push-relabel algorithm for ordinary maximum flow can be extended to the parametric problem while only increasing the worst-case time bound by a constant factor...

The ECOPATH II microcomputer software is presented as an approach for balancing ecosystem models. It includes (i) routines for balancing the flow in a steady-state ecosystem from estimation of a missing parameter for all groups in the system, (ij) routines for estimating network flow indices, and (iii) miscellaneous routines for deriving additional indices such as food selection indices and omn...

Assembly lines are flow-oriented production systems that are of great importance in the industrial production of standard, high-volume products and even more recently, they have become commonplace in producing low-volume custom products. The main goal of designers of these lines is to increase the efficiency of the system and therefore, the assembly line balancing to achieve an optimal system i...

Steven T. Taylor, P.E., is a principal and Jeff Stein, P.E., is a senior engineer at Taylor Engineering in Alameda, Calif. Taylor is a member of TCs 4.3 and 1.4. He is a former member of ASHRAE Standing Standards Project Commitee (SSPC) 90.1 and former chairman of SSPC 62.1. ow, and indeed whether, to balance variable flow (twoway valve) hydronic systems has been debated for many years.1,2,3 In...

In order to enhance multicast communication, it is important to investigate effects of network coding which can be a typical application of active network. In this paper, we study the feasibility of network coding based multicast architecture from performance aspect. We first show that the network coding based multicast has not only high transmission capacity with the max-flow, which is an orig...
