한국형 생태산업단지 구축 및 자원화 순환망 구축에 관한 연구
임창호,이동석 江原大學校 産業技術硏究所 2009 産業技術硏究 Vol.29 No.B
Recently, SID (Sustainable Industrial Development) or green growth is the major concern of industries. EIP (Eco Industrial Park) is one of the important part of SID which aims to improve eco-efficiency of resources such as material, energy and water. In this study, current status of Banwol & Sihwa industrial complex relating EIP was investigated and the plan to design of Banwol & Sihwa EIP was suggested.
산업용 6관절 로봇의 원격제어를 위한 실시간 병렬데이터통신 인터페이스

This paper presents the development of the I/O Interface for the real time parallel data communication between controller of a six-axis industrial robot(CRS -A460) and an external computer. The proposed I/O Interface consists of the hardware I/O interface and the software that is downloaded to the robot controller and executed by the controller operating system. The constitution of the digital I/O Port for CRS-A460 robot controller and the digital I/O board for IBM-PC are presented as well as the Process Control Program of the robot controller. The developed protocol for the parallel data communication is described. The data communication is tested, and the performance is analysed. In particular, it is shown that the real-time constraint of the robot controller process is satisfied.
OEB(Open Electronic Book) 표준을 지원하는 Viewer의 설계와 구현
이승란,서주하 江原大學校 産業技術硏究所 2001 産業技術硏究 Vol.21 No.A
e-book is digital contents using IT technology instead of paper. It is carried in Internet and displayed wish Viewer of PC, PDA or terminal. The Open eBook specification is to provide a specification for representing the content of electronic books to these viewers. The specification is based on HTML and XML, the same core languages that define the World Wide Web, and is designed to allow publishers and authors to deliver their material in a single format. In this paper, we design and implement the viewer that can support OEB(Open eBook) standard. Viewer is composed parser part and display part. In audition, we add some functions - the book shelf, the bookmark and the dictionary - for convenience of readers.

매모그램 구조의 전기저항 영상법에서 정방향 모델의 고유전류 계산 알고리즘

Electrical impedance tomography (EIT) is a technique for determining the electrical conductivity and permittivity distribution within the interior of a body from measurements made on its surface. One recent application area of the EIT is the detection of breast cancer by imaging the conductivity and permittivity distribution inside the breast. The present standard for breast cancer detection is X-ray mammography, and it is desirable that EIT and X-ray mammography use the same geometry. A forward model of a simplified mammography geometry for EIT imaging was proposed earlier, In this paper, we propose an iterative algorithm for computing the current pattern that will be applied to the electrodes. The current pattern applied to the electrodes influences the voltages measured on the electrodes. Since the measured voltage data is going to be used in the impedance imaging computation, it is desirable to apply currents that result in the largest possible voltage signal. We compute the eigenfuncdons for a homogenous medium that will be applied as current patterns to the electrodes. The algorithm for the computation of the eigenfunctions is presented. The convergence of the algorithm is shown by computing the eigencurrent of the simplified mammography geometry.
초음파 센서를 이용한 Edge Position Controller (하드웨어)
전진욱,박찬원 江原大學校 産業技術硏究所 2007 産業技術硏究 Vol.27 No.B
We have developed a Edge Position Controller (EPC) using a ultrasonic sensor and applied to a fabric machine as a web guide system. Hardware devices composed of a ultrasonic transmitter-receiver sensor module and microprocessor-based sensor signal processing system are developed to realize the proposed system. We evaluated the control characteristics of the EPC and the performance of the system was good enough to apply the actual system.
