We developed an on-line lathe simulator which can be used for a CAM education on the internet. Previously, VRML or static images such as JPG have been commonly used to achieve the same goal. With the 3D tool like VRML, it was possible to describe the movement of 3D object effectively. However, G-code based modeling and real-time visualization for the cutting process including parts being machined could not be accomplished. By using the simulator, we can machine a part with G-code input from a user or modeler, and parts being machined can be visualized in 2D as well as 3D. The developed system is based on EMCO lathe from Eshed and can be used through a web browser.

Due to the fast growing rate of the global container trade, every major port is under the pressure of meeting the projected capacity demand. As a result, alternative solutions have been sought for improving capacity and meeting the growing demand for container storage area and terminal capacity. Moreover, material handling process re-engineering is now a critical issue for logistics and supply chain managers of airline, shipping lines, terminal and warehousing enterprises around the world. Therefore, the purpose of this paper is to develop the 3D simulator for executing performance valuation of port transportation systems. The developed 3D simulator system is to measure the effectiveness of the proposed total system and compare it with existing practices. The performance analysis variables are also defined for these comparisons

By using FACS(Facial Action Coding System) and linear interpolation, a 3D facial robot simulator is developed in this paper. This simulator is based on real facial robot and synchronizes with it by unifying protocol. Using AUs(Action Unit) of each 5 basic expressions and linear interpolation makes more various dynamic facial expressions.

In this work, we have developed a 2 degree of freedom(DOF) motion simulator that can generate the sensation of motion in a 6 DOF space. The motion base has the DOF of roll and pitch, and the purpose of the motion base is to create the sensation of riding a vehicle in a 3D space by controlling the motion base. The dynamics of the mechanism was analysed and the optimal design of the motion base mechanism has been reached. The prototype motion base mechanism was developed and tested. The multi-axis motion controller(MMC) was used to control the two ac servo motors that drive the roll and pitch motion.

This paper deals with generating multi-ped mobile robot's optimal path and its simulation. The multi-ped robot has six-legs which make it possible to move actively by attached driving wheel at the end of legs. The simulation environment is created similarly to the indoor environment as simple obstacles and walls. Also simulator can reconstruct an simulation environment. In this paper, the suggested simulator can generate the optimal path from starting point to destination by applying the A* algorithm and Bug2 algorithm. Then it is possible to check algorithms as 3D screen and we can simulate under the generated path.

Embedded capacitor technology is one of the effective packaging technologies for further miniaturization and higher performance of electric package systems. So we used the 3D EM simulator for embedded capacitor design in 8-layed PCB(Printed Circuit Board). The designed capacitors value are 2 pF, 5pF, 10 pF, respectly. we investigated characteristics of capacitance - frequency and SRF(Self Resonance Frequency) as changing the rate of hight and width of upper pad of embedded capacitors.

This paper presents an experimental technique to accurately separate a permanent magnetic field and an induced one from the total magnetic fields generated by a steel ship, through compensating for the Earth's magnetic field. To achieve this, an Earth's magnetic field simulator was constructed at a non-magnetic laboratory, and the field separation technique was developed, which consisted of five stages. The proposed method was tested with a scaled model ship, and its permanent and induced magnetic fields were successfully extracted from the magnetic field created by the ship. Finally, based on the separated permanent magnetic field data, the permanent magnetization distribution on the hull was predicted by solving an inverse problem. Accordingly, the permanent magnetic fields generated by the ship can easily be calculated at any depth of water.

Qualitative elevation of products is very important Part. A business racking us brains to find for qualitative elevation of products. Recently, measurement accuracy of a non-contact 3D scanner has been rapidly improving. As a result, the number application cases of non-contact 3D scanners are increasing. A non-contact 3D scanner is capable of measuring a curved surface rapidly and has high resolution. It is more affordable and potable than the CMMs, It is therefore expected to be applied more frequently in more diverse industries. Automating the measuring process using a non-contact 3D scanner and developing a technology, which allows a user to measure easily, will eventually improve the quality of products. As their inspection and analysis processes improve.

가상현실 (VR) 시뮬레이터의 임장감 증대방법을 제안했다. 이 방법은 입체영상과 3차원음향 사이의 상호 상승효과에 의하여 인간이 느끼는 현실감을 증대시키기 위한 것이다. 상호 상승효과를 실험하기 위하여 PC 모니터와 LCD 셔터그래스로 구성된 VR 시뮬레이터를 이용하여 5명의 대학생을 대상으로 주관평가를 실시하였다. 실험결과, 입체영상에 3차윈음향을 부가한 경우, 자연감을 나타내는 척도 $I_{nat}$ 가 3.1에서 3.6으로 0.5 상승하고, 음상정위 평가척도 $A_{SL}$ 는 70~75%에서 80~85% 로 10% 상승하는 결과를 나타냈다. 따라서, 이 연구에서 제안한 방법이 VR 시뮬레이터의 현실감을 증대시킬 수 있었다.
