The flutter reliability analysis of long span bridges requires use of a software tool that predicts the uncertainty in a flutter response due to uncertainties in the model formulation and input parameters. Existing flutter analysis numerical codes are not capable of dealing with stochastic uncertainty in the analysis of long span bridges. The goal of the present work is to develop a software tool (FREASB) to enable designers to efficiently and accurately conduct flutter reliability analysis of long span bridges. The FREASB interfaces an open-source Matlab toolbox for structural reliability analysis (FERUM) with a typical deterministic flutter analysis code. The paper presents a brief introduction to the generalized first-order reliability method implemented in FREASB and key steps involved in coupling it with a typical deterministic flutter analysis code. A numerical example concerning flutter reliability analysis of a long span suspension bridge with a main span of 1385 m is presented to demonstrate the application and effectiveness of the methodology and the software.

We proposed a modularization design technique for implementing software of on-board train control system. We already proved the efficiency of CASE Tool(SCADE) for safety critical software design. The several functions of train are implemented on CASE tool each modules. We divided functions of train into modules based on the modularization design. We used MATLAB for design of on-board train control software. We proved that this technique is more useful for the software design of on-board train control for EMU.

Bioinformatics education can be defined as the teaching and learning of how to use software tools, along with mathematical and statistical analysis, to solve biological problems. Although many resources are available, most students still struggle to understand even the simplest sequence alignment algorithms. Applying visualizations to these topics benefits both lecturers and students. Unfortunately, educational software for visualizing step-by-step processes in the user experience of sequence alignment algorithms is rare. In this article, an educational visualization tool for biological sequence alignment is presented, and the source code is released in order to encourage the collaborative power of open-source software, with the expectation of further contributions from the community in the future. Two different modules are integrated to enable a student to investigate the characteristics of alignment algorithms.

Data structure and algorithm are primary courses for computer programming instruction. However, now those are not interesting courses for students because the programming instruction methodologies that used these courses are not the proper methodologies for the visual and windows programming. The Sorting programming is the same as other data structures. Therefore, we developed the VTSPI (Visualization Tool for Sorting Programming Instruction) which is a software component to instruct sorting program effectively for solving these problems. As a result, students can code, understand and debug their programs because VTPSI is software components based on visual programming.

A S/W testing for vital railway signaling system have been important because of the increase of software usage for signaling. And also the safety of vital signaling system is required by int'l std. such as IEC 61508. While much efforts have been reported to improve electronic hardware's safety, not so much systematic approaches to assessment software's safety. In this paper, we propose a automation schemen of software testing tool for railway signaling system. From that, we show the functional architecture and internal components of the tool.

In Part 2, dynamic cutting force model, thermal behavior model, and feed drive model are presented for development of a virtual machine tool. Some relevant results with brief descriptions for each model are presented to verify the proposed models. Experimental results for each model agreed well with the estimated ones. The developed models in this two-part paper are partially integrated as a comprehensive software environment.

The train control and monitoring system(TCMS) is an on board computer system in railway vehicles performing the control, supervisory and diagnostic functions of the complete train. This system replaces a lot of hardwired relays and minimizes the necessaries vehicle wiring thus increasing the reliability of the train. In this paper, we proposed a software design technique of TCMS using CASE tool (SAO+). The TCMS functions are implemented in software easily programmed, using a functional block, graphic programming language. We applied the compressor air module to a case study.
