The automatic determination of vehicle operation status as well as continuous tracking of vehicle location with intelligent management is one of major elements to achieve the goals. Especially, vehicle operation status can only be analyzed in terms of expert experiences with real-time location data with scheduling information. However the scheduling information of individual vehicle is very difficult to be interpreted immediately because there are hundreds of thousand vehicles are run at the same time in the national wide range workplace. In this paper, we propose the location-based knowledge management system(LKMs) using the active trajectory analysis method with routing and scheduling information to cope with the problems. This system uses an inference technology with dispatching and geographic information to generate the logistics knowledge that can be furnished to the manager in the central vehicle monitoring and controlling center.

CNC technology is used in various industrial fields, whose best example is the product part. The technology has been applied to machine tools such as automatic lathes and machining centers, etc. Recently, CNC technology has been applied not only to industrial parts but also to consumer part such as dental prosthesis and 3D face carving machine. In this paper, we introduce the application of the CNC technology to the 3D face carving machine, which the public has been not familiar with yet. It enables general users to control the machine and get the product with ease. We also mention examples of the application of the technology to the related fields and the way open CNC technology is used in controlling the calving machine.

Press brake is used as bending and forming sheet metal in vehicle and many kind of industry. This paper deals with development of NC press brake based on high precision positioning device and software, which can be operated on personal computer. In this system, positioning device is used for controlling bending angle and operated by the developed software, which is database from material property, width and thickness of material. This study will make distribution in development of computer aided press brake.

In this paper, we try to develop the controller which uses the block diagrams of SIMTool and internal functions CEMTool for planning the global driving controller for high efficiency AGV. We acquire the control efficiency by controlling the motor used each part of AGV driving controller. The block diagram structures provided with SIMTool is easily designed by the controller, and the monitoring and analysis of the results is researched by simulation. We expect to control AGV. robot and various plant using Ziegler-Nichols auto-tuning method and external I/O board

This paper presents a dialogue interface using the dialogue management system as a method for controlling home appliances in Home Network Services. In order to realize this type of dialogue interface, we annotated 96,000 utterance pair sized dialogue set and developed an example-based dialogue system. This paper introduces the automatic error correction module for the SMS-styled sentence. With this module we increase the accuracy of NLU(Natural Language Understanding) module. Our NLU module shows an accuracy of 86.2%, which is an improvement of 5.25% over than the baseline. The task completeness of the proposed SMS dialogue interface was 82%.

An automatic visual classification system is introduced which provides for measuring the length and diameter of coilform cores and dividing them into 5 different classed in terms of how far their length be from the desired length. This task is fully automated by controlling two STEP motors and by using image processing techniques. The classification procedure is broken into three logical parts, First, cores in the form of randomly stacked bundle are lined up one by one so as to be well captured by a camera. The second part involves capturing core image. Then, it enters the measuring process. Finally, this machine would retain all the information relating to the length. According to the final result, cores are sent to the corresponding bin. This considerably simplifies the selecting task and facilitates a greatly improved reliablity in precision. The average classifying capability is about 2 pieces per second.

The definition of multi-coupled operation is that coupled two trainsets is able to be operated one trainset identically. That is to say, the one driver, coupled two trainsets can operate the traction and braking system, control vehicle doors, phanto-graph, HVAC and passenger room lighting system etc, such as one trainset controlling. This study will provide high speed train design engineer with introducing multi-coupled operation system electrically and presentation automatic complex coupler mechanism, and then this paper will be applied to design next generation high speed train system such as Jun-la/Ho-nam line

Under high temperature and high pressure, cyanogen disinter gration distruction mechanism brought followings results through continuous plug flow reactor system. 1. The temperature was a important reacting factor in cyanogen disintegration. Over $612.8^{\cird}K$ high disintegration rate or 99.99% was shown even under $2000{\;}mg/{\ell}$ cyanogen density. 2. The conditions of cyanogen disintegration was gained through experimenting the supercrietical condition of water in basic. To gain 99.99% disintegration rate under $1000{\;}mg/{\ell}$ early cyanogen density, the pressure showed 52.8 seconds at $523^{\cird}K$ and 84.2 atm and gained $0.56{\;}mg/{\ell}$ operating density. 3. Here is the reaction velocity formula of cyanogen disintegration by hydrolysis: This formula indicates the high possibility of cyanogen disintegration within a short time. And it also implys the potential possibility on treating NBDICOD and the technology in developing the environment cleaning progress as small size automatic controlling equipment.
