A computer program for matrix structural analysis by object-oriented programming technique using $C^{++}$ language has been developed. Object, class, method and inheritance which are used in object-oriented programming are illustrated using a graphical representation. The matrix operations and the structural analysis by matrix displacement method were satisfactorily performed by the proposed program. Numerical tests demonstrate that this proposed program can be widely used for the matrix structural analysis for personal computers.s.

In this paper, an efficient storage reclamation algorithm for RISC parallel processing in the object orented programming environments is presented. The memory management for the dynamic memory allocation and the frequent memory access in object oriented programming is the main factor that decreases RISC parallel processing performance. The proposed algorithm can be efficiently allocated the memory space of RISCy computer which is required the frequent memory access, so it can be increased RISC parallel processing performance. The proposed algorithm is verified the efficiency by implementing C language on SUN SPARC(4.3 BSD UNIX).

A computer program for matrix structural analysis by object-oriented programming technique using C/sup ++/ language has been developed. Object, class, method and inheritance which are used in object-oriented programming are illustrated using a graphical representation. The matrix operations and the structural analysis by matrix displacement method were satisfactorily performed by the proposed program. This object-oriented programming concepts can be widely used to develop the finite element structural analysis program for personal computers.

We propose a unmaned integrating control system based-on Windows XP version Off-Line Programming System which can simulate a Robot model in 3D Graphics space in this paper. The robot with 4 and 6 axes modeled SM5 and AM1 respectively were adopted as an objective model. Forward kinematics, inverse kinematics and robot dynamics modeling were included in the developed off-line program. The interface between users and the off-line programming system in the Windows XP's graphic user interface environment was also studied. The developing language is Microsoft Visual C++. Graphic libraries, OpenGL, by silicon Graphics, Inc. were utilized for 3D Graphics.

The main purpose of this paper is a study on the automatically implementing a Multi user server education system and homepage via web browser from toolkit embedded Multi user server unix server Perl programming language and c language was used to make this toolkit. With using window based web browsers, the user can make they own classroom homepage. In this paper, we propose the single user server version and Multi user server version of this toolkit. With use of ftp, the Multi user server version of this toolkit can make homepage to other unix server workstation

The Unified Modeling Language(UML) became the standard object oriented modeling language approved by Object Management Group(OMG). However, C++ codes which are generated by some CASE tools supporting UML do not reflect the correct semantics of one-to-many relationship and aggregation relationship. Additionally, since the commercial CASE tools support too many programming languages on one UML class diagram, they do not support efficiently the characteristics of C++ language. Our C++ code generator supports one-to-many relationship, aggregation relationship, code patterns and design patterns. In this paper, we describe design and implementation of the efficient C++ code generator based on UML class diagram.

The educational courses for the procedural-oriented and object-oriented programming languages have been prepared respectively in many universities. However, the comparison of two languages has not been shown in the same class. In this paper, we compared two distinctive languages, C and Java, and developed a new class material and the relating web contents, through which those who are interested may maximize their understanding and programming skills based on the different programming language.

This paper describes implementation of a robot programming system for automation of manufacturing products, which is embedded in the C programming language. World representation and motion primitives necessary to describe a manipulator task are provided by a set of procedure calls and user defined data structures. Off-line programming is implemented with graphic simulation as a debugging tool. PUMA 560 manipulators are used as a model for one task which inserts a nonstandard power IC Iota PCB. Communication facilities are provided for collision avoidance or two manipulators.

This paper presents a speed control of AC servo system using LabVIEW program and cRIO (Compact RIO)hardware which is a real-time controller made in National Instruments company. LabVIEW is a GUI programming language easy to implement control system and cRIO is a reconfigurable hardware platform which is very simple. Therefore Lab VIEW and cRIO will be excellent tools to design and implement control system.
