Psychophysiological monitoring of operator state has been developed over the past decades as measures of mental workload, fatigue, and inattention. This paper provides examples of the application of these measures to classify operator functional state (OFS) and further to implement adaptive aiding. Examples using several levels of mental workload are presented to show that combinatorial classif...

The present paper describes a set of procedures for the solution of nonlinear static-equilibrium problems in the complex multibody mechanical systems. To find the equilibrium position of the system, five optimization techniques are used to minimize the total potential energy of the system. Comparisons are made between these techniques. A computer program is developed to evaluate the equality co...

It has been identified that financial institutions are one of the major users of Information Technology hence the need to evaluate effective use of the computer security strategies. This study aimed at evaluating the effectiveness of computer and network security strategies employed in Nigerian banks. This study was led by the following objectives; to determine and assess the security strategie...

In this paper we describe the distribution problems faced by one of the largest retailers in the distribution and sale of fast moving consumer goods in the U.K. The paper describes an initial solution method, which is then improved by a novel form of simulated annealing. A computational experiment for the improvement algorithm has been also carried out in order to illustrate the flexibility of ...

Nowadays, the capability of cloud management suppliers is one of the important advantages for suppliers that can improve the performance and flexibility and reduce costs in companies through easy access to resources. Also, the environmental impacts of suppliers are a significant issue in today’s industrialization and globalization world. This paper analyzes these subjects by fuzzy multi-objecti...

this article presents a transient model of a solar adsorption cooling system. a computer program has been developed to simulate the operation of a two bed silica gel- water adsorption cooling system as well as flat plate collectors and the hot water storage tank. this program is then utilized to simulate the performance of a sample solar adsorption cooling system used for cooling a set of rooms...
