On most PaaS (Platform as a Service) systems, applications that are developed on a server are executed on the same server. As such, portability of these applications is not considered as is the case with a WebOS. This paper proposes a Web-based Software Development Environment (WSDE) for developing applications. The WSDE provides a web-based development environment for software applications that can be executed on a server, local and/or embedded machine. Thus, it is unnecessary for each developer to install software for developing applications on the local system or to set the environment variables of the local system. With the WSDE, developers can use the same environment via a Web browser anytime, anywhere. Moreover, this paper proposes a renewable system for embedded systems. To develop application programs for embedded systems, application developers have to prepare a software development environment for each target embedded system. The WSDE allows software developers to develop software applications on a server using a virtual machine. © 2012 IEEE.

Cloud computing, which has become very popular in recent years, can be categorized as SaaS (Software as a Service), PaaS (Platform as a Service), or IaaS (Infrastructure as a Service). PaaS provides a platform similar to a software development environment over a network. On most PaaS systems, applications that are developed on a server, are executed on the same server. As such, portability of these applications is not considered. This paper proposes a Server-side Development and Client-side Execution (SDCE) Environment for developing GUI applications. The SDCE provides a Web-based software development environment for GUI applications that can be executed on a local machine. © 2012 IEEE.

In this paper, FEM procedure is applied to the static and dynamic analyses of R/C structures. Simple R/C shell structure is solved by using FEM procedures and the experimental evaluations are performed to represent the applicability of FEM procedure to R/C structures. Also, R/C columns are analyzed numerically and experimentally. On the basis of these results, FEM procedures are applied to the R/C cooling tower structures assembled by huge R/C shell structure and a lot of discrete R/C columns. In this analysis, the parallel computing procedures are introduced into these analyses to reduce the computational effort. The dynamic performances of R/C cooling tower are also solved by the application of parallel computations as well. From the numerical analyses, the conventional FEM procedures combined with computational technologies enables us to design the huge R/C structures statically and dynamically.

The stress distributions and the ultimate strength of a reinforced concrete (R/C) cooling tower shell were investigated under the conditions of uneven settlement of column supports. In numerical analyses, the finite element method was adopted. R/C cooling tower shell and columns were modeled by solid elements and steel sheet elements representing the reinforcements. The behaviour of two types of supporting systems, that were 32 V column and 32 vertical column systems, was investigated and was compared under the loading condition of the self weight. From the numerical analysis, the stress concentration was arisen near the connections between the unsettled column and the lintel and the ultimate strength was reduced by uneven settlements. © Copyright 2016 by the International Association for Shell and Spatial Structures (IASS).

We have studied the relative complex permittivity (r r′- ir″) of copper granular composite materials containing coagulated Cu particles in the microwave range as well as the electrical conductivity. The insulator to metal transition was observed at the percolation threshold c 16.0 vol. . The enhancement of permittivity in the insulating state can be described by the Effective Cluster Model. Above the percolation threshold c, it was found that the Cu granular composites show negative permittivity spectra below a characteristic frequency f0 indicating the low frequency plasmonic state. Characteristic frequency tends to increase with particle content. © 2013 AIP Publishing LLC.
