Many people from various sectors are now talking about the “Smart” things such as devices for work, home, education, and so on. Smart is another word for intelligence. Smart learning can be defined as a quite innovative way of getting the knowledge, especially in advanced science and technologies. Smart learning environments are always connected with WiFi,(More)
Computational science and engineering (CSE) researchers usually develop their own technology computer-aided design (TCAD) programs, accompanying large-scale computation and I/O on high-performance computing (HPC) resources like clusters or supercomputers. The researchers typically use command-line interface (CLI) such as Terminal to access the HPC(More)
In e-science environments, scientists need to execute a scientific application with various parameters multiple times to simulate and experiment complicated problems on the grid. For this, they should write every single job description with distinct parameters even if this is a troublesome task. To provide the flexibility and adaptability for parameter(More)
Effective scientific data management is crucial for e-Science applications. Scientific data management raises challenging requirements: (1) support for not only experimental data but also context data, (2) both schema evolution and integration, (3) and compatibility with legacy data management conventions or environments. In this paper, we present a(More)
Computer simulations are widely used in various fields of science and engineering, including computational fluid dynamics. As the demand for the accuracy and quality of simulations grows, the cost of executing simulations itself is also rapidly increasing. However, until now, the reuse of previously obtained simulation results to improve the execution of(More)
A new capability of our well-known NEMO 3-D simulator (Ref. Klimeck et al., 2007 [10]) is introduced by carefully investigating the utility of III–V semiconductor quantum dots as infrared photodetectors at a wavelength of 1.2–1.5 μm. We not only present a detailed description of the simulation methodology coupled to the atomistic sp3d5s∗ tight-binding band(More)
Recently new techniques to efficiently manage biological information of biology have played an important role in the area of information technology. The flavonoids are members of a class of natural compounds that recently has been the subject of considerable scientific and therapeutic interest. This paper presents a Grid-based flavonoids web portal system.(More)
We have developed a web-based e-Learning service for education and research in nanoscience areas. Being named as EDISON (EDucation-research Integration through Simulation On the Net) Nanophysics, the service framework presents various technology computed-aided design (TCAD) tools, with which users can study fundamentals of physics, explore properties of(More)
