The purpose of interlocking system was to prevent the route for a train being set up and its protecting signal cleared if there was already another, conflicting route set up and the protecting signal for that route cleared. Recently, the computer based control systems instead of conventional relays circuitry are widely used to industrial systems, therefore, interlocking system are rapidly changing from relay interlocking system to computer controlled interlocking system that control requirements of interlocking at junctions using electronic circuits. However, the reliability of interlocking logic for those systems are harder to demonstrate than in traditional relays circuitry because the faults or errors can not be analyzed and predicted to those systems, In this paper, by examine checking technique of computer controlled interlocking system, we will to acquire interlocking inspection algorithm and method for computer controlled interlocking system

This study proposed an SCA advice system. It is an ontology-based recommender that provides advice on appropriate computer curricula based on the behavior of high school students. The three computer curricula at Chiang Mai Rajabhat University include computer science (CS), information technology (IT), and web programming and security (WEB). This study aims to design the ontology framework for an SCA advice system. The system considers three core ontologies: student, computer-curriculum, and advice. After analyzing student behaviors, the behavior types of CS, IT, and WEB were determined to be SB-2, SB-1, and SB-5, respectively. All subjects in these three curricula were analyzed and grouped into seven groups. Their curricula were synthesized in terms of basic skills, basic knowledge, and characteristics. Finally, advice results can be obtained by consolidating the curriculum nature of the CS, IT, and WEB curricula.

This paper attempts to develop the algorithms and computer program for load flow solution and faults analysis of large power system by small digital computer. The Conventional methods for load flow solution and fault analysis of large power system require too much amount of computer memory space and computing time. Therefore, this paper describes the methad for reducing the computer memory space and computing time as follows. (1) Load Flow Solution; This method is to store each primitive impedance of lines along with a list of bus numbers corresponding to the both terminals of lines, and to store only nonzero element of bus admittance matrix. (2) Faults Analysis: This method is to partition a large power system into several groups of subsystems, form individual bus impedance matrix, store them in the storage, and assemble the only required portion of them to original total system by algorithm.

본 논문은 스마트 팩토리의 중요 요소인 무인반송차(AGV)를 자율 주행시키기 위해 오픈 소스 자율 주행차 시뮬레이터인 udacity를 이용해 머신 러닝시키는 시스템을 개발하였다. 공장의 운행 루트를 자율주행 시뮬레이터의 전경으로 가공하고, 3개의 카메라를 부착시킨 AGV를 운행시키면서 머신 러닝시킨다. AGV를 주행하여 얻어진 여러 학습 데이터를 통해 도출된 결과들을 각각 비교하여 우수한 모델을 선정하고 운행시킨 결과 AGV가 정해진 운행 루트를 정확하게 주행하는 것을 확인하였다. 이를 통해, 가상 운행 환경에서 저비용으로 AGV 운행 학습이 가능하다는 것을 보였다.

World is moving towards digitization at a rapid pace, so the enterprises have developed information systems for management of their business. Empowering educational institutes with information systems are become very important and vital. Doing everything manually is very difficult for students, teachers and staff. Information system can enhance their efficiency and save a lot of time; this research proposed system will solve this issue by providing services like class room reservation, e-library facility, online submission etc. in a secured environment. Up till now limited attention has been paid to utilize robots and drones for automation inside educational institutes. Our proposed system incorporates robots and drones to fill this gap in automation being used in institutes. Through this research, the aim is to improve the efficiency of learning and services in educational institutions or universities.

The primary concern here is to discover the what and how of the computer same development. In other words, the goal of this research is help the evaluation of Creative Croup Thinking System (CGTS), become aware of areas of need for the development computer game. For the development computer game, the creative thinking is one of the most important principles. The creative thinking is the first step of the development computer game of process. In order to save time, effective qualifies, and achieve the goals, the researcher has studied the web programing on the Creative Croup Thinking System (CGTS).

The major advantages to use CAD System are that it reduce time and effort to manufacture products, and also can demonstrate the condition of the final product prior to the actual manufacturing process of the selected design using the simulation programs in CAD system. Specially in weave design, for use as Computer-Aided Weaving system, the complicated Dobby weave can figured out easily through calculating the complex weave plans of multi shafts. As to one of dobby weave structures, Supplementary warp is the warp threads which are in addition to the regular warps of the woven fabrics, and used for decorating the band or expressing some patterns. The purpose of this study is to research the weave design of Supplementary warp using Computer-Aided Weaving system, which is dobby weave design program of Weave Point. For performing this design study, it was researched the classified woven fabrics depending upon weaving processing, Computer-Aided Weaving system, and the characteristic of Supplementary warp fabrics. On the basis of the theoretical research, Supplementary warp was worked for the 24-shafts AVL computer dobby loom that applied to the various patterned images. The design work was done by Weave Point program of dobby weave, and simulated to fabrics before woven into the computer dobby loom. To see the visual images of fashion items, these simulated bobby fabrics were processed by three-dimension modeling through YoungWoo CNI CAD system. All the patterns of the Supplementary warp in this study could be applied for decorating the fashion clothing and accessories.
