KARI studied data interface of Space Applications for developing Space Experimental Instrument in International Space Station, designed, and manufactured the UDIS (International Space Station Universal Data Interface simulator) according to requirements of the data interface. This paper explains the design and implementation of UDIS for space application. UDIS is the instrument which simulate to interface the data from ISS to experiment module, payload and habitation module and use the development of a experiment system in the space. This simulator will be used to the GSE (Ground Support Equipment) for test of experiment system. By realization of the simulator, we ensure data interface skills for a manned-space data communication system.

Intermediate Representation(IR)은 컴파일러가 Target code 를 생성하기까지의 중간 단계에서 프로그램을 표현하는 수단이다. 본 논문에서는 컴파일러의 IR을 직접 Simulation 해서 각종 profiling information을 수집하여 프로그램의 성능 향상에 도움을 줄 수 있는 IR Simulator를 제안하고자 한다. 더 나아가 IR Simulator를 위한 Data structure와 Interface는 Target Simulation에도 재사용이 가능하도록 고안되었기 때문에 재겨냥성 컴파일러의 Target Simulator를 자동으로 생성하는 연구를 진행하고 있다.

As make a simulator including user interface functions like start & stop, load parameters, record and save, view 3D display has a real-like length and numerical value of sizes, represent real-shape of inner and outer part of robot, make the possible fast and slow selective observation as a adjust a step, receiving the images through the image device which attached in robot, so make a motion tester simulator of humanoid robot which coded by windows based GUI(Graphic User Interface) program with a MMI(Man Machine Interface) function that user can watch the environment which included robot and use a images. For implement this, we use a design data that converted data which made by use a CAD for Laser RP(Rapid Prototyping) progress into C coding for simulator programming. Using OpenGL, an API of graphic, it has a efficiency and detail of graphic operation. To make and test animation data, it has the option of save and resume in animation.

Global Navigation Satellite System (GNSS)/Inertial Navigation System (INS) integrated navigation systems provide highly accurate and reliable navigation solutions and are widely used as civil and military navigation systems. In order to facilitate the GNSS/INS integrated navigation system development task, a simulator can be used to provide inputs for the GNSS/INS integrated navigation system. In this paper, a simulator design using general-purpose Personal Computer (PC) and Off-The-Shelf (OTS) interface boards for a GNSS/INS integrated navigation system is proposed and implementation results are presented. Requirements of the GNSS/INS integrated navigation system simulator are presented and a design method that satisfies the requirements is described. In order to show the usefulness of the proposed design method, a simulator using a general-purpose PC and OTS interface boards for the GPS/INS integrated navigation system are implemented and verified. The implementation results show that the simulator designed by the proposed method generates the GPS L1 C/A signal and IMU data without any problems.

We present a use. interface(UI) simulator for developing a mobile phone. This simulator consists of 3 major modules: Graphic Tool Editor, User Interface Software(UI), and Network Command Processor(NCP). The Graphic Tool Editor can design a virtual mobile terminal. The NCP sends a command to the phone and then receives its status from the phone after completion of the command. We can add or modify lots of features easily to the phone using the UI module. These modules can interact each other by sharing the common area in the memory. By doing so, these modules can exchange their status and data to operate in real-time. We have designed and tested a virtual prototyping phone for the LGP 3200 manufactured by LGIC by using the simulator. Through a series of experiment, we have believed that our virtual prototyping interactive simulator can do shorten its development and testing cycle by applying it in the early design phase.

This paper include the results of the software interface design for the ground vehicle simulators. This design allows us to upgrade the simulator easily by exchanging the engineering model when we need to change the function of algorithm or data of a simulator. That is because a main part of simulator is composed of reusable model.

In this paperwe develop a real-time simulator for direct drive cooperative robot by using OpenGL in a Windows NT based system. This simulator is composed of 2 parts, a display part and an interface part. In the display part the robot is modelled and rendered in 3D space. To do this OpenGL, a kind of graphic library, is used for rendering and animating robots and kinematics gives the information of the current robot configuration. The control and the feedback data are sent and received via the interface part. In real time simulation interfacing part needs fast data transfer rate and good nosic immunity. In experiment we have simulated 2-link direct drive cooperative robots using the trajectory tracking algorithm proposed in reference.

A simulator has been developed in order to simulate and to be used to design the pervaporation system for separating organic/water mixtures. This simulator is composed of simulation engine, which includes a modeling of pervaporation system and the numerical analysis, and Graphical User Interface(GUI), which enables us to operate the simulator more easily in the Windows environment. The structure and operation of simulator were clearly presented by demonstrating the full-scale ethanol dehydration process. The performance of simulator turned out to be fairly good through comparing the simulation results with the experimental data of ethanol dehydration pilot tests.

The reliability, that is Long-Term Quality, require an approaching different from Short-Term Quality which is used before. As the electronic components are able to be easily normalized on the reliability testing, various testing standards are used. In this study, we proposed two reliability simulator that is PoF(Physics of Failure)-based and failure rate models-based. PoF-based simulator is introduced based on CalceEP program that is created by University of Maryland. This simulator can be modified by user interface of properties and PoF models and operated on stand alone system. Failure rate models-based simulator introduced according to analyzing reliability prediction documents. Also, unified database including failure data models is built from existing MIL-HDBK-217F N2, PRISM, and Bellcore, and web-based simulator is developed. The developed reliability simulator will service of the PoF model, properties, failure rate model accumulated and its data by web and internet.
