The computational method based on using the operational matrix of anorthogonal function for solving variational problems is computeroriented. In this approach, a truncated Hartley series together withthe operational matrix of integration and integration of the crossproduct of two cas vectors are used for finding the solution ofvariational problems. Two illustrative...

Introducing object-oriented problem solving and programming has shown to be more difficult than expected. The way we "used to do" do not work as well as it did with the imperative approach. In an attempt to compare how people conceive the idea of objects and object oriented design/ problem-solving subject to the way it is taught, we conducted a study during Summer-University 2001. The aim was t...

A semantic enabled multi-agent architecture for solving non-linear equations systems by using a service oriented approach is proposed. The service oriented approach allows us to access already implemented methods for solving complex mathematical problems. The semantic descriptions of these services provide support for intelligent agents. The proposed architecture is a framework with two extensi...

Introduction Problem solving, and technological problem solving in particular, is clearly a critical survival skill in our technologically advanced world. Government, business, vocational and technology education leaders have increasingly called for more emphasis on higher-order thinking skills and problem solving in both general and technological areas. The American technology education profes...

A typical computing environment for solving Grand Challenge Problems consists of a high performance graphics workstation acting as a front-end, connected to a variety of remote supercomputers. A Problem Solving Environment (PSE) is a system of programs designed to assist a scientist in solving his/her problems without detailed understanding of parallel machines, and guiding him/her through the ...
