Network-based learning or e-Learning has been taking an important role in education as helpful education tools. However, it is difficult for teachers to retrieve education data from students or to obtain data from the student activities. Therefore, we have developed a problem solving environment (PSE) for the education and learning support: TSUNA-TASTE. The(More)
In this paper, we describe a problem solving environment (PSE) for grid computing called NAREGI-PSE in the NAREGI (National Research Grid Initiative) project, conducted by MEXT (Ministry of Education, Culture, Sports, Science and Technology) of Japan. NAREGI-PSE is researched and developed to support the scientists' works for scientific computer simulations(More)
A distributed problem solving environment (PSE) is proposed to help users solve partial differential equation (PDE) based problems in scientific computing. The system inputs a problem description and outputs a program flow, a C-language source code for the problem and also a document for the program. Each module is distributed on distributed computers. The(More)
A problem-solving environment (PSE) for a distributed high-performance computing (HPC) is proposed to help users to work on distributed computer environment. When users access and use distributed computers for scientific computations, the PSE tells users which computers are available and appropriate for their specific application software by using hardware(More)
NAREGI is a Japanese National Grid Project started in 2003, whose chief aim is to develop a set of Grid middleware to serve as a basis for future e- Science. In this paper, we describe a software tool called NAREGI-PSE (Problem Solving Environment), which aims to supports the scientists¿ works for scientific computer simulations on widely-distributed(More)
This paper presents a method based on the use of an image sensor for obtaining the complex amplitudes of beams diffracted from an object at two different wavelengths. The complex amplitude for each wavelength is extracted by the Doppler phase-shifting method. The principle underlying the proposed method is experimentally verified by using the method with(More)
