In the information storage development, the trend of the storage device is to increase the recording density. Among such an effort, near-field probe recording is spotlighted as a method of high increasing recording density. For the successfully embodiment of storage device, the actuating mechanism of near-field probe is essentially designed. In this paper, we suggest the slider similar with conventional HDD and design the slider using near-field probe for the purpose of applying the slider in order to control gap between probe and media. The most important object of slider design is to guarantee the flying ability and stability. For achievement of these design objects, we perform two step of optimal design process. The media is supposed to model as random displacement, which is only considered roughness of disk surface. The design slider is analyzed with dynamic state in assumed media. At this process, the optimal model is confirmed to stable flying stability.

The flight simulator should be made like a actual flight. For the scene of sight, instrument should show the condition of flight and the pilot should catch the altitude, speed, pose and rate of lift of the airplane. The paper describes 3D flight visual training program of driving airplane in practice. It is for beginners using joystick in PC, implements airplane physical equations. And it uses rendering technology to implement vision parts of flying object.

In this paper, we designed a line CCD camera for a flying image, which is composed of a line CCD sensor(2048 cells) and a rotating mirror, and investigated its optical properties. We also made the 3-D image from the flying image which is made of 2-D image being juxtaposed to 1-D images obtained by the camera, and performed the calibration to acquire high precision 3-D data. As a result, we obtained the 3-D measurement system using the slit type of laser projector is available to measure the high precision shape of objects.

탐지레이더는 저고도로 비행하는 물체를 탐지할 목적으로 국방 분야에서 운용하고 있다. 레이더가 탐지한 원시자료는 즉시 정보화되어 의사 결정체계인 지상전술C4I체계에 입력되고 분석을 거친 후 사용자에게 실시간으로 전파되어야 한다. 그러나 현 수작업 표정작업은 운용자의 능력에 따라 정확성 및 적시성이 미흡한 실정이다. 따라서 이 논문에서는 레이더 자료를 이용하여 실시간 항적을 표시할 수 있도록 체계에 대한 개념연구, 요구사항 분석, 설계를 통하여 항적추적관리시스템을 구현하였다. 적용된 핵심기술은 좌표 체계 전환 알고리즘과 기존 통신장비와의 통신프로토콜 개선, 신호 및 자료처리 프로세스를 설계에 반영하였다. 특히, 레이더 신호의 중복처리 및 융합 알고리즘을 개발하여 상황도상에 표적정보를 도시하는 기술을 구현함으로써, 기존 항적관리전력 운용의 신뢰성, 신속성, 편의성을 향상시킬 수 있었다.

The real time modeling of dynamic system on adaptive control system is very important for flying control system(FCS). Using traditional method, it is required much calculation load for integral/differential at control system. Therefore, It is very important theme of study in these days to find algorithms for integration/differential at FCS. These algorithms for integral/differential influence strongly stability/reliability to control flying object. In this paper, we present optimal predictive sampling time for reduce calculation load at FCS and optimal predictive time on general cost function by applying adaptive control method.

This paper presents the design and implementation of a Mission Planning System(MPS) for multiple ballistic missiles. MPSs are also a kind of M&S systems in defense domain, and these provide important computations on the ground before flights of flying objects. The proposed MPS in this paper has a new concept which is far from generating a set of waypoints of a flying object and proving the set. In this paper, we firstly discuss the research motivation of our own MPS; then, we introduce the design of our MPS and its functionalities. In order to prove the practicality of our MPS, we have conducted a case study.
