그리드 컴퓨팅 기술을 기반으로 한 원격 실험 환경 구축에 있어서 원격 실험만큼이나 실험결과 데이터를 저장하고 재연하는 것이 중요하게 대두되고 있다. 본 논문에서는 KOCED 프로젝트의 건설 연구 실험시설 중 하나인 실시간 하이브리드 다자유도 실험시설에 대한 프로토타입인 원격 하이브리드 실험에 대하여 나라다 브로커링 이라는 발간 및 구독 패러다임의 스트리밍 서버와 글로버스 툴킷에 기반 한 리코딩 및 리플레이 서비스를 통하여 실험결과 데이터를 저장하고 재연하는 시스템을 구축 하였다. 기존에 진행된 실험결과를 검색하여 볼 수 있게 함으로써 중복된 실험으로 인한 비용을 줄이고, 사용자가 원하는 데이터에 대한 토픽정보를 통하여 재연함으로써 실험결과 데이터의 효용성을 높일 수 있을 것으로 판단된다.

사람감지를 통한 영상녹화 시스템은 컴퓨터가 입력받은 영상으로부터 사람인 부분을 감지하고 녹화하는 시스템이다. 영상처리를 기반으로 한 사람감지 방법은 그 내용이 비교적 난해하고 학습량이 방대하기 때문에 관련 분야의 입문자들이 직접 구현하기에 어려움이 수반된다. 따라서 이 논문은 초보자들이 해당 분야에 보다 쉽게 접근할 수 있도록 하기 위해 공개 소스 컴퓨터 비전(OpenCV) 라이브러리의 사람 감지 API를 제공한다. 또한, 이를 이용해 웹캠을 통해 입력받은 영상에서 사람인 부분을 표시해주고, 녹화하는 시스템을 구현하였다.

In this paper, we developed an integrated miniaturized device which acquires and transmits the signal of ECG an interested heartbeat and body's temperature. Electrocardiogram(ECG) is a recording of the electrical activity on the body surface generated by heart. ECG & temperature measurement is collected by wireless sensor (for Ag/AgCl Thin-Film) placed at designated locations on the body. It is that dual wireless sensor will apply variously to Ubiquitous & Healthcare System.

LDM, easy to minute position control, is using as X-Y plotter or other recording instruments. Brushless LDM has better properties than the conventional Brush type LDM in many aspects. This paper presents magnetic flux density distribution by FEM and a way to reduce thrust force ripple particurary in low speed drive. And we apply this method to a real mode of LDM. This LDM is operated by IBM-PC host computer and uses rotary encoder to make position signal.

Continuous temperature monitoring and event recording provides information on the energized equipment's response to normal and emergency conditions. On-line temperature monitoring helps to coordinate equipment specifications and ratings, determine the real limits of the monitored equipment and optimize facility operations. Using wireless technique eliminates any need for special cables and wires with lower installation costs if compared to other types of online condition monitoring equipment. In addition, wireless temperature monitoring works well under difficult conditions in strategically important locations. Wireless technology for on-line condition monitoring of energized equipment is applicable both as standalone system and with an interface with power quality monitoring system. The paper presents the results of wireless temperature monitoring of switchgear at a power plant over a two-year period.

According to the evolutive theory of saline, combined with field survey data, the authors have discussed the theoretical model of recording past climatic change of Luobupo saline. After interpreted and analyzed the causes of the ringy image, the authors have mapped high resolution climatic changing graph of Luobupo saline during past 2000 years by using remote sensing method. Contrast to the known results, it is proved that the research results have comparability and continuity. The resolution of special climatic event can reach in one year, and in general, the resolution of climatic change can reach in ten to twenty years.

Magnetic hard disk drive is continually being pushed to reduce head-disk spacing for higher recording densities. The current minimum spacing between the air-bearing slider and disk has been reduced to under 15 nm. In this work, it was investigated if flying height could be lowered under the height of laser bumps. With the reduction of the spinning speed, the flying height was decreased under the height of laser bumps. When a head swept between landing zone and data zone, the head-disk impact was monitored using AE and friction signals. It is demonstrated that magnetic hard disk drive could be operated without tribological failures under the height of laser bumps.

The interface between nanomaterials and biosystems is emerging as one of the broadest and most dynamic areas of science and technology, bringing together biology, chemistry, physics and many areas of engineering, biomedicine. The combination of these diverse areas of research promised to yield revolutionary advances in healthcare, medicine, and life science. For example, the creation of new and powerful nanosensors that enable direct, sensitive, and rapid analysis of biological and chemical species can advance the diagnosis and treatment of disease, discovery and screening of new drug molecules. Nanowire based sensors are emerging as a powerful and general platform for ultrasensitive and multiplex detection of biological and chemical species. Here, we present the studies about noble metal nanowire sensors that can be used for sensitive detection of a wide-range of biological and chemical species including nucleic acids, proteins, and toxic metal ions. Moreover, the optical and electrochemical applications of noble metal nanowires are introduced. Noble metal nanowires are successfully used as plasmonic antennas and nanoelectrodes, thereby provide a pathway for a single molecule sensor, in vivo neural recording, and molecular injection and detection in a single living cell.

Near field technology makes it possible to overcome the diffraction limit of laser beam and create the small spot. Because of the small spot size, the pit size and track pitch can be decreased. So the high performance actuator is needed for near field recording system. And the light mass and the small form factor are also important properties of the NFR actuator in order to be used for hand held device. The purpose of this paper is the optimal design of the NFR coarse actuator to maximize actuating force. The structure of NFR coarse actuator is the same as HDD VCM actuator. The permeance method is used for modeling of the coarse actuator. The optimal result and the FEM simulation result are presented.
