This paper introduces a constrained recon gurable mesh model which incorporates practical assump tions about propagation delays on large sized buses Simulations of optimal recon gurable mesh algo rithms on the constrained recon gurable mesh model are found to be non optimal Optimal solutions for the sorting and convex hull problems are then presented For the problems investigated the con strain...

While extensive use of software in technical systems necessitates a multi-domain systems perspective education has increasingly focused on specific fields of engineering science. Project-based learning (PBL) attempts to overcome this disconnect with authentic problem solving at the core of the approach. A medium-sized Cyber-physical system (CPS) is presented that includes sufficient detail to h...

We present an accurate, stable, and efficient solution to the Lippmann–Schwinger equation for electromagnetic scattering in two dimensions. The method is well suited for multiple scattering problems and may be applied to problems with scatterers of arbitrary shape or non-homogenous background materials. We illustrate the method by calculating light emission from a line source in a finite-sized ...

We discuss the application of a parallel implementation of a hybrid genetic algorithm (GA) to the airline crew scheduling problem. Tests on 40 real-world problems were carried out on an IBM SP parallel computer. The algorithm was able to solve to optimality all but one of the small and medium-sized problems, and found good solutions for half of the larger problems. Two limitations were identifi...

The objective function of the genome rearrangement problems allows the integration of other genome-level problems so that they may be solved simultaneously. Three examples, all of which are hard: 1) Orientation assignment for unsigned genomes. 2 ) Ortholog identification in the presence of multiple copies of genes. 3) Linearisation of partially ordered genomes. The comparison of traditional gen...

Since the middle of 1980s, the stock structure of English and US enterprise has extremely dispersed, and the governance mode of “stockholder first” has been suspected extensively because many problems such as the protection of middle and small sized stockholder benefit and anti-annexing, and the problems of interior personnel control and agent costs are more and more serious. After that, the th...

delivering perishable products to customers as soon as possible and with the minimum cost has been always a challenge for producers and has been emphasized over recent years due to the global market becoming more competitive. in this paper a multi-objective mix integer non-linear programming model is proposed to maximize both profits of a distributer and the total freshness of the several produ...

We consider an open shop scheduling problem with setup and processing times separately such that not only the setup times are dependent on the machines, but also they are dependent on the sequence of jobs that should be processed on a machine. A novel bi-objective mathematical programming is designed in order to minimize the total tardiness and the makespan. Among several mult...
