본 논문에선 리드 솔로몬 복호기의 오류갯수를 판별하는 마이크로콘트롤러의 새로운 설계법을 제시한다. 본 설계법을 통해 기존보다 빠르고 훨씬 회로량이 줄어든 최적화된 오류갯수 판별기용 산술논리연산장치회로를 설계할 수 있었다. 이 리드솔로몬 복호기는 거의 모든 디지털 통신 및 가전기기의 데이터 보존기기의 보호장치로 사용되어질 수 있다. 여기서는 제곱계산회로의 최소화가 가능해 병렬처리를 통해 오류갯수 판별기의 최적화를 이룰 수 있었다.

In this paper, a controller design for brushless linear motor is implemented. The designed controller is mainly composed of current, speed and position controller, which are carried out by the high-speed digital signal processor (DSP). In addition the PWM inverter is controlled by space voltage PWM method. This system is implemented by using 32-bit DSP (TMS320C31), a high-integrated logic device (EPM7192), and IPM (Intelligent Power Module) for compact and powerful system design. The experimental results show the effective performance of controller for the brushless linear motor.

This study is investigates space syntax theory, developed by Bill Hiller, used for physical analysis and visual access of space and role of spatial configuration based on social logic. it mean computer program analyze physical structure of space and represent by mathematical logic. it used for predict space use and Descriptive of spatial configuration. This method and theory is incompletion for design, but it enough useful tool for architecture and urban design and will be improved. And development of a simple computer program - SSA(Sspace Syntax Analysis) for space syntax analysis and study. SSA is based on convex map analysis and using VISIO software for easily using and development.

An analog signal conditioner using fuzzy logic technique, which has multiple-input and multiple-output terminals, is proposed in this paper. The proposed signal conditioner can be employed to linearly translate the level of signals to a standard voltage signal (1-5V) and convert the form of signals to a standard current signal (4-20mA). The implementation method based on the use of a commercial 8-bit microcontroller, the analog-to-digital (A/D) converters, the digital-to-analog (D/A) converters and the voltage-to-current (V/I) converter. The simulation result and the experimental results are presented, which further confirm the feasibility of this approach.

In this paper, a controller design for coreless linear synchronous motor is proposed. The designed controller is mainly composed of speed and current control, which are carried out by the high-speed digital signal processor(DSP). In addition the PWM inverter is controlled by space voltage PWM method. This system is implemented using by 32-bit DSP(TMS320C31), a high-integrated logic device(EPM940), and IPM(Intelligent Power Modules) for compact and powerful system design. The experimental results show the effective performance of controller for coreless linear synchronous motor.

This paper presents a virtual laboratory system which can be creating efficiencies in the learning process. The proposed virtual laboratory system for digital logic circuits provides interactive learning environment under which the multimedia capabilities of world-wide web can be enhanced. The virtual laboratory system is implemented to describe the on-campus laboratory, the learners can obtain similar experimental data through it. The virtual laboratory system is composed of four important components: principle classroom simulation classroom, virtual experiment classroom and management system. The database connectivity is made by PHP and the virtual laboratory environment is set up slightly differently for each learner. Learning efficiencies as well as faculty productivity are increased in this innovative teaching and learning environment.

In this paper, we propose a digital differential protection of power transformer using intelligent schemes. Intelligent schemes is based on fuzzy logic and neural networks. To enhance the distinction between fault and inrush of conventional approaches, relaying technique by fuzzy logic and neural networks are used. We used transformer inrush currents, external and internal fault signals, which are obtained from EMTP simulation.
