  • In this paper, an integrated optimal design software system for structural components has been developed which interfaces existing commercial codes for CAD, CAE and Optimization. They include specialized optimal design software codes such as iSIGHT and VisualDOC, optimization module imbedded in CAD software developed by CAD developers, and optimal design software systems based on API of commercial CAD software. The advantages of the CAD imbedded optimal design approach and those of specialized optimal design software are taken to develop the system. The user defines optimal design formulation in the user interface for problem definition in the CAD control stage, where design variables are directly selectable from the CAD model and various properties and performance functions defined. The commercial CAD codes, Open I-DEAS are used for the development. The resulting software is minimally connected to CAD and CAE systems while keeping maximum independence from each other. This assures flexibility and freedom for problem definition. Fatigue life optimization is taken as a nontrivial application area. As a specific example, the shape design of a knuckle part of an automobile is performed, where the minimum fatigue life over the material domain in terms of the number of cycles of a curb strike are maximized under the constraint of not exceeding the current mass. The fatigue life has been improved by four times of the initial life. The developed software is illustrated to maintain the advantages of existing optimal design software systems while improving independency and flexibility.

  • Recently, rainfall induced hazard has been increased gradually, for example, typhoon Rusa in 2002 and Maemi in 2003. In addition, localized heavy rainfall has been also caused tremendous damage to railroad systems. Measured data from the Meteorological Adminstration sometimes, However, are not in accordance with those of rain gauges in local area, because of its good distance. This study develop automatic alarming software to estimate and prevent these kind of rainfall induced hazards in railroad system with online transportation.

  • Collaborative product commerce(CPC) involves many people working together with heterogeneous and distributed software applications. For such an environment, Workflow Management System(WFMS) can be useful for coordination of people, software agents and processes. It provides diverse services including automatic work muting, project management continuous process improvement and application integration. However, there are some limitations to apply WFMS to CPC environment due to inflexibility and lack of design support facilities. This paper identifies the problems and addresses possible approaches to overcome the difficulties.

  • 오늘날 우리는 HTML 폼을 통해 지역 데이타베이스뿐 아니라 원격 데이타베이스도 쉽게 접근할 수 있다. HTML 폼으로 데이타베이스 웅용을 구현하는 것이 쉽기는 하나 아직 HTML 폼과 CGI 프로그램은 코딩되어야만 한다. 본 논문에서는 웹 기반 데이타베이스 웅용을 자동 생성하는 도구를 소개하는데, 이 도구는 응용 데이타베이스 구축을 위한 SQL 문장들, 사용자 인터페이스로 사용되는 품들, 그리고 그 폼들을 통해 이루어진 질의를 처리하는 자바 서블릿을 생성한다. 생성될 테이블들과 폼들은 응용을 위한 클래스 다이어 그램으로부터 결정된다. 따라서 WebSiteGen으로 명명한 우리의 소프트웨어 도구는 웹기반 데이타베이스 응용의 구현을 자동화한다.

  • We study on the implementation of reconfigurable position control system which is based on Open Control Platform(OCP) for Unmanned Expedition Vehicles(UEV) in ubiquitous environment. The control system uses hierarchical control structure and OCP structure which contains three layers such as core OCP, reconfigurable control API(Application Programmer Interface), generic hybrid control API. The goal of our research is to implement an UEV control system using advanced software technology. As a specific control problem, we study a transition management problem between PID control and neural network control depending on fault or parameter change of the plant, i.e., UEV. The concept of the OCP-based software-enabled control can provide synergy effect by the integration of software component, middleware, network communication, and control, and thus can be applied to various systems in ubiquitous environment.

  • 최근 증강현실을 활용한 UAV 응용 시스템 개발에 많은 관심이 집중되고 있다. 일반적으로 UAV 응용 시스템 개발에서는 실제 비행 실험을 수행하기 전에 SILS 기법을 적용하여 시스템의 설계 및 구현을 검증하고 있다. 그러나 기존 SILS 환경은 증강현실 관련 핵심 사항들을 반영하지 못하고 있으므로 증강현실을 활용한 UAV 응용 시스템에 대한 효과적인 검증이 불가능하다. 본 논문에서는 이러한 문제를 극복하기 위하여 증강현실과 UAV 기반 응용 시스템 개발에 효율적으로 활용될 수 있는 SILS 플랫폼을 제안하였다. 정확성, 효율성, 확장성에 대한 모의 실험 결과는 제안하는 플랫폼이 증강현실과 UAV 기반 응용 시스템 개발에 효과적으로 활용될 수 있음을 보여준다.

  • Business process in e-government mostly embody as the flow of documents. Constructing a web-based document flow system becomes an critical task for today s digital government. But few of them use an off-the-shelf workflow product. Why? One of the reasons is that most of the workflow system are heavyweight, monolithic, and package a comprehensive set of features in an all-or-nothing manner. Another reason is that workflow technology lacks the constructs and modeling capability as programming language. It is incumbent on government IT organizations to transform their solution development to component-based computing model. Component technology isolates the computation and communication parts, but how to compose different software components is still a hard nut. An integrated development environment is necessary for CBSD. In this paper we propose a XML and component-based document flow-oriented integrated development environment (DFoIDE) for software developers. By writing some xml configure file, and operate on DFoIDE, developer can construct a workflow application quickly. This method divides system to several components and the activities in process are implemented as business component. Different components are discribed detailedly in this paper, especially one of the core component. Component Integrating Tool. Different perspectives in workflow application are seperated and depicted as different XML files. Correspondly, A component composition method for developing workflow application instead of workflow itself is proposed.

  • A new optimization scheme and some key techniques are proposed in the development of a vehicle glass drop design software system. The key issues of the design system are how to regenerate the glass surface and make the vehicle glass drop down along the glass channels. To resolve these issues, a parameterized model was created at first, in which the optimizing method and Knowledge Fusion techniques were adopted the optimized process was then written into the glass drop design system by coding with C language and UGS/Open Application Programme Interface functions etc. Therefore, the designer or engineer can simulate the process of glass dropping along the channels to assess the potential interference between glass and door accessory by using this software system. All of the testing results demonstrate the validity of the optimizing scheme, and the parametric design software effectively solves the key issues on development of the door accessory package.

  • The accuracy of global navigation satellite system(GNSS) positioning has been studied during the last decades. Early GPS software was developed as monolithic tool in which all functions packed in the same software. But, these GPS software have the problems of the high cost of constructing system. close system architecture and the reusability. And there is a lack of interoperability between them because most of them have their own unique data format according to their application fields. In this paper, we have introduced requirements for design and specifications based on business process for the GPS system. commonly used to extract components from the requirements of the GPS business-based development process is presented. These components extracted by the process can be used to assemble components only. In particular, applications for developers to add features specific case without affecting the other components that can be modify the component.

  • In this paper, we have proposed an architectural solution for a system for the visualization and modification of large amounts of data. The pattern is based on an asynchronous execution of programmable commands and a reflective approach of an object structure composition. The described pattern provides great flexibility, which helps adopting it easily to custom application needs. We have implemented a system based on the described pattern. The implemented system presents an innovative approach for a dynamic data object initialization and a flexible system for asynchronous interaction with data sources. We believe that this system can help software developers increase the quality and the production speed of their software products.
