This program is based on analyzing the emitted spectral line shape via utilizing facilities of the MatLab7? package to perform this task. This software can perform the following tasks;read the exported data file (*txt-format) from ICCD camera-software, specify the working wavelength of interest, removes the continuum emission component appeared under the line, calculates the spectral line intensity of the line, calculates the spectral shift of the line from the tabulated values, correct against spectral shift jitter at the peak emission, de-convoluting and extracting the different components contributing to the emitted line full width at half of the maximum (FWHM) and finally calculates the plasma electron density. In this article we shall present the results of the test measurement of the plasma electron density utilizing spectral line shape analysis to the emitted Hα-line, Si I-line at 288.15 nm and O I-line at 777.2 nm at different camera delay times ranging from 1 to 5 μs.展开更多

In this paper,firstly we introduce the context of MPEG-7,MPEG-7 objectives and parts. Then we analyze the MPEG-7 eXperimentation Model(XM) reference software, including application types,software models and the implementation of descriptors and description schemes. Finally we discuss the possible application of MPEG-7 in AVTMS.展开更多

As more and better communication is required with other fusion research laboratories, remote access to experimental data is becoming increasingly important in order to raise the degree of openness of experiments and to expand research results. The web-based remote data browsing system enables authorized users in geographically different locations to view and search for experimental data without having to install any utility software at their terminals. The three-tier software architecture and thin client technology are used to operate the system effectively. This paper describes the structure of the system and the realization of its functions, focusing on three main points： the communication between the participating tiers, the data structure of the system and the visualization of the raw data on web pages.展开更多
