This paper presents the implementation of an efficient car tracking system based on Inverted DGPS (IDGPS) using mobile phone and internet for data communication link. The IDGPS technique, which may provide the same level of accuracy as DGPS, is subject to degradation in real time applications when transmission time delays occur in the communication links. Therefore, an effective communication system is the key element for successful application of the IDGPS. The combination of internet and mobile phones provides a high data rate, unlimited communication packet size, flexible data structure, and wide coverage without additional communication devices. An implementation of such a data link system is described. Field test results are included to evaluate the performance of the proposed system.

The derivative equation measured of a MV=Kp8{(EVn-EVn-1)+Ki/S/1* EVn+(Kd/s)*(2PVn-1-{PVn-PVn-1)}(원문이미지참조) is used on the machine apparatus of industrial field, but this par doesn\`t able to educate now, because we didn\`t have the implementation device of PID module, so the principle implementation system of the PID Module is manufactured and developed. Through this system, the implementation system of PID Module is practiced with that the SV and the set of P, I, D is set on the derivative equation measured of PID. A things to be known of this experiment result is flow. 1)PID module is known that had to be used with the module of A/D and D/A. 2) In process of PV is approached to the SV to follow Kp, Ti and Td to cause a constant of set value on the MVp=Kp*EV, Mv=Ki/1 EVdt, MVd+tDBT/D EV(원문이미지참조) the variable rate of E and Kp, Td, Ti in that table 1 is analysed, is same as flow. ①If Kp is high, PV is near fast to the SV, but Kp is small, PV is near slowly to the SV. ②If Ki is shot, PV is close fast to the SV, but Ti is high, PV is close slowly to the SV ③If Td is high, the variable rate of E press hardly when because it doesn\`t increase, but Td is small, the variable rate of E press not hardly, upper with 1),2), PID module is supposed that be able to do the A/S and an implementation of that apparatus, and getting a success of aim that an engineer want, on control of temperature, tension, velocity, amount of flow, power of wind end so on, to get the principle of automatic implementation in industrial field with cooperation of A/D and D/A module.

In this paper, we consider the implementation of connected digit recognition system using tree structured lexicon model. To implement efficiently the fixed or variable length digit recognition system, finite state network (FSN) is required. We merge the word network algorithm that implements the FSN with lexical tree search algorithm that is used for general speech recognition system for fast search and large vocabulary systems. To find the efficient modeling of digit recognition system, we investigate some performance changes when the lexical tree search is applied.

This paper deals with implementation of middleware using CAN(Controller Area Network) network and TCP/IP for real-time distributed control system of a humanoid robot. Existent system using CAN network is available. But, there is problems in extensibility and flexibility. In this raper, the new system using TCP/IP for solution and improvement of problems is proposed. The new system is applied to ISHURO-II, real-humanoid robot. The performance is verified through experiment.

The importance of training for NC, CNC and Machining Center has been greatly increased. This paper presents implementation of a DNC system and operating software for educational purpose. This system is able to connect 8-32 CNCs to Control PC with RS232 multi-port serial card. Therefore, it allows much efficiency in training even after costs are considered. The KISCO DNC S/W for above system includes various communication function, communication parameter setting, program editor, tool management and user-friendly environment.

This paper describes a duplexed process control system for a boiler-turbine system of power plant, which is composed of supervisor, controller, and simulater subsystems. Its embeded POL(Problem oriented language) as a structured control language enables this system to do a real-time distributed control and fault diagnosis by simple programming with the actual implementation of advanced control algorithms such as PID autotuning and GPC, etc, the performance of overall system has been greatly enhanced.

On a bus-based shared memory multiprocessing system, the system bus monitoring and analysis are crucial for system integration test and performance analysis. In this paper, the design and implementation of a bus monitoring instrument for the TICOM-III system are decribed. The instrument dedicated to TICOM-III, which is called the Bus Information Procssing Unit, analyzes the bus state and measures the bus utilization. It performs many useful functions to help debugging the system, and offers a simple user interface.

This paper has studied a management system for RCST of the Satellite Multimedia Internet Service through analysing the architecture and specification of BSAN based on Digital Video Broadcasting System. In this paper, designing and implementing RCST DPM and agent system are shown. The UCD-SNMP framework served as base station for implementation of the agent. And the message protocol between RCST DPM and agent system has been also defined to provide a way for interaction.

본 연구에서는 ERP 구축과정을 4개의 단계(사전준비단계, 프로젝트단계, 정착단계, 향상단계)로 나누고 각 단계별 완성도가 전체성과에 미치는 영향을 측정하고, 동시에 4단계간에 이전단계의 완성도가 다음단계의 완성도에 어떠한 영향을 미치는지를 살펴보았다. 각 단계별 완성도와 ERP 성과와의 관계를 검증한 결과, 프로젝트 단계와 향상단계의 완성도가 전체성과에 유의한 영향력을 미치는 것으로 나타났다. 동시에 각 단계별 완성도간 관계를 살펴본 결과 모든 이전단계의 완성도는 바로 다음단계의 완성도에 매우 강한 영향력을 끼치는 것으로 조사되었다.
