  • An object oriented programming(OOP) framework is presented to solve plane elastostatic contact problems by means of the boundary element method(BEM). Unified modeling language(UML) is chosen to describe the structure of the program without loss of generality, even though all implemented codes are written with C++. The implementation is based on computational abstractions of both mathematical and physical concepts associated with contact mechanics involving geometrical nonlinearities and the corner node problems for multi-valued traction. The overall class organization for contact analysis is discussed in detail. Numerical examples are also presented to verify the accuracy of the developed BEM program.

  • It has been required to develop a defect detection system to perform defect detection capabilities after the bonding process in the production of RFID tags. However, we are difficult to design a system with understanding the characteristics of RFID tags and design concepts. Also we are difficult to modify even minor changes in features. In this paper, we design the defect RFID detection system using UML and object-oriented design techniques. We suggest the method for apply the UML Diagram to LabVIEW OOP and the technique for redesign the effect detection system's changes.

  • In this paper, we develop protocol analyzer that can analyze and monitor LAN(Local Area Network)-based TCP/IP protocol using the OOP(object-oriented programming) in Windows98/NT environment. TCP/IP(Transmission Control Protocol/Internet Protocol) protocol analyzer is consist of interface hardware, protocol analysis software and GUI(Graphic User Interface). It is designed for the real-time analysis using the real-time object. In results of Performance test, TCP/IP Protocol analyzer is showed that it can analyze and monitor without frame error in LAN-based. Also, developed protocol analyser operates better than conventional protocol analyzer in performance. It can be used in maintenance fields of communication and network.

  • 국제수로기구(IHO)는 수로분야의 다양한 데이터와 서비스 표준개발을 위한 프레임워크인 S-100 표준을 개발 하였으며, 이를 기반으로 차세대 전자해도 표준을 포함하는 제품 및 서비스 표준을 개발하고 있다. S-100 기반 제품표준을 개발하기 위해서는 S-100 표준에 부합하는 Feature Catalogue(FC)가 포함되어야 하며, 이를 지원하기 위해 S-100 Feature Catalogue Builder(FCB)가 개발 되었다. S-100 FCB를 이용하여, FC제작 시 Feature를 정의하기 위해서는 Attribute를 매번 입력 하게 되는데, 공통 Attribute를 입력함에 있어서의 입력 오류와 장시간의 제작 시간이 소요된다는 문제점이 발생한다. 이러한 문제점은 현 S-100 FCB가 객체지향 개념이 고려되지 못한 것으로 판단하고, 본 연구에서는 OOP(Object-Oriented Programming) 기반의 S-100 FCB 개발 방안을 연구하였다. 이를 통해 중복되는 정보의 입력을 줄이고 제작 시간을 단축 할 수 있을 것으로 예상된다.

  • 컴포넌트는 컴포넌트 기반 개발(Component Based Development, CBD)기술에서 재사용되는 기본 단위로서 OOP(Object Oriented Programming, OOP)의 객체보다 상대적으로 큰 단위의 기능성을 제공하며 재사용성이 뛰어나다. 모델 기반 아키텍처(Model Driven Architecture, MDA)는 모델들 간의 다양한 변환(Transformation)을 활용하여 어플리케이션 개발을 자동화하는 새로운 패러다임으로서 소프트웨어의 생산성을 향상시킨다. 그러나 MDA 는 컴포넌트와 같은 어플리케이션들 간의 공통성과 가변성을 활용한 재사용성을 직접적으로 지원하지는 않는다. 본 논문에서는 CBD 와 MDA 의 장점과 한계점을 알아보고 서로의 단점을 보완할 수 있도록 컴포넌트 PIM 과 컴포넌트 기반의 MDA 공학 프로세스를 제안한다. 제안된 컴포넌트 PIM 과 프로세스를 이용하면 어플리케이션들 간의 공통성과 가변성을 이용한 뛰어난 재사용성과 자동화를 통한 생산성의 ,향상 및 높은 유지보수성을 가질 수 있다.

  • This study aims to construct a management system of road position information as part of the build-up to a maintenance and management system of highways. First, information on the positions of the roads were obtained by a real-time kinematic satellite surveying, and then the degree of accuracy was analyzed in comparison with the data of the existing design drawings. The linear coordinates of road center line obtained by using RTK GPS showed about 7.6-13.2cm errors in X and Y directions in the case of the national road No.2 section, and about 8.4-9.2cm errors in the case of local road No.1045 section. These errors were within the tolerance scope regulated by the TS survey, and could be practically used. In the case of vertical alignment, there were about 6.2cm errors in the Z direction in local road No.1045 section. Aerial photographs are normally used in producing numerical maps, and it can be practically used because the tolerance scope of the elevation control point is l0cm when the scale of aerial photographs is 1/1000. The management system of road position information, utilizing Object-Oriented Programming(OOP), was built having the data acquired in this way as the attribute data. The system developed in this way can enable us to spot the positions of road facilities, the target of management with ease, to easily update the data in case of changes in the positions of roads and road facilities, and to manage the positions of roads and road facilities more effectively.

  • As a system becomes more complex, a design relies more heavily on a methodology based on high-level abstraction and functional verification. SystemVerilog includes characteristics of hardware design language and verification language in the form of extensions to the Verilog HDL. However, the OOP of System Veri log does not allow multiple inheritance. In this paper, we propose adoption of SystemC to introduce multiple inheritance. After being created, a SystemC unit is combined with a SystemVerilog-based verification environment using SystemVerilog DPI and ModelSim macro. Employing multiple inheritance of SystemC makes a design of a verification environment simple and easy through source code reuse. Moreover, a verification environment including SysemC unit has a benefit of reconfigurability due to OOP.

  • This paper reports the effort for developing this new Unified Manufacturing Instruction Set and its environment, called here UniSet, to deal with difficulties in set up and operation of Flexible Manufacturing Cells, UniSet has been developed as a non-exclusive unified manufacturing instruction set based on com- parisons of the prevailing machine tool and programming primitives. UniSet allows programmers to deal with only one instruction set, if they so desire, in a single coherent enviroment, rather than numerous machine programming languges. The software system is coded in an Object-Oriented Programming (OOP) language, Smalltalk, and derives its paradigm from the OO philosophy. Test results are also includ- ed to demonstrate the applicability of the approach employed.

  • 개발된 프로그램은 C++ 언어를 사용하여 객체지향 프로그래밍 (Object Oriented Programming) 개념에 맞추어 설계되었다. C++과 같은 OOP 언어는 클래스 정의, 연산자 오버로딩, 상속, 캡슐화와 같은 차별적인 특성을 가지고 있어 대규모 프로그램의 작성과 관리에 매우 효과적이다. 전력 계통의 각 구성 요소들은 클래스로 설계되었으며 계산 모듈 또한 별도의 클래스로 디자인하여 향후 프로그램 개선과 확장을 용이하게 구현하였다. 개발된 프로그램은 편리한 Graphic User Interface (GUI)를 제공하기 위해서 Windows Application Programming Interface (API)와 Microsoft Fundamental Classes (MFC) 등을 이용하였으며 Microsoft Visual Studio.net 을 이용하여 컴파일 되었다 [1].

  • In this paper, the load balancing which is one of the distribution power system's operation purposes was studied. Reconfiguration of Distribution power system presents that the configuration is changed by changing the switch on/off status which exists in the system according to the mentioned purpose. Through this method, the load of distribution power system is shown to be balanced. As a characteristic of complicated distribution power system, system is designed by being applied by OOP(Object Oriented Programming) method which connected more flexibly than existing Procedural Programming method, and the process of calculating the distflow and the loss of configurated system is shown. In addition, this paper suggests more efficient method compared by the results of reconfiguration on the purpose of the loss minimization and by the result of distribution power system reconfiguration on the purpose of load balancing. Moreover, it searches for the method to approach the global optimal solution more quickly.
