Abstract
 
최근 국제 물류에서 화물 컨테이너의 운송을 보다 안전하고 효율적으로 관리하기 위하여 수•출입 절차 규제가 강화되고 있다. 화물 컨테이너의 안전하고 효율적인 운송 및 화물 정보의 안전한 전달을 지원하는 대표적인 보안장치로는 전자봉인(E-Seal: Electronic Seal)과 CSD(Conveyance Security Device)가 있다. E-Seal은 ISO TC 104SC4WG2에서 국제 표준화 작업을 진행했으며, 표준문서 번호는 ISO 18185규격번호를 가지고 있다. 범용성이 우수하기 때문이다. E-Seal은 국제표준 논의를 통해 등장한 기술인 반면 컨테이너 보안장치는 국제표준화 작업없이 미국의 GE에서 독자적으로 개발한 RFID장치이며, GE와 더불어 유럽의 지멘스, 한국의 삼성물산, 일본의 미쓰비시 등의 산업체를 중심으로 상용화가 추진되고 있다. CSD는 컨테이너의 내부에 설치되며 컨테이너 봉인시점(POA)에서 중간지점(ITP)을 거쳐 미국의 도착항(TTP)까지 Shipping Se-curity를 보장하는 것을 목표로 한다. 국내에서도 이러한 기술의 확산에 대비하여 응용서비스 및 시스템의 개발에 노력하고 있다. 본 세미나에서는 각 기술의 개발 동향과 이를 응용한 국내의 연구동향을 소개한다.

Abstract

A recently developed ultra-wideband (UWB) balun opens new possibilities for the low-cost, mass-producible, and surface mountable UWB components with 10’s of GHz bandwidth. The balun is a simple microstrip-to-coplanar stripline transition structure, but a single balun can be designed to have operating frequency range from DC to over 40 GHz. The balun design is based on optimal impedance matching and smooth field transformations between adjacent transmission lines. Utilizing this uniplanar balun, new low-cost and mass-producible components—e.g., mixers, doublers, antennas, detectors, differential amplifiers, etc.—with 10’s of GHz bandwidth are being developed. The new UWB components can also be designed in the form of low-cost surface-mountable chips, which may open new commercial UWB application areas.
In this presentation, the design of the ultra-wideband balun will be described, and recent developments of new UWB components utilizing the balun will also be introduced

Abstract

Network design optimization is basically a fundamental issue in the various fields, including applied mathematics, computer science, engineering, management, and operations research. Network models provide a useful way for modeling various real world problems and are extensively used in many different types of systems: communications, mechanical, electronic, manufacturing and logistics. However, many practical applications impose on more complex issues, such as, complex structure, complex constraints, and multiple objectives to be handled simultaneously and make the problem intractable to the traditional approaches.

Recent advances in evolutionary algorithms such as genetic algorithm, genetic programming, and evolution strategy have made it possible to solve such practical network design and scheduling problems. The seminar talk introduces Network Design Techniques based on Evolutionary Algorithm such as the shortest path model for Internet OSPF Routing Model and Car Navigation System, several minimum spanning models, bicriteria max flow/minimum cost flow problem and capacitated QoS (Quality of Service) network model:

Part 1: Multiobjective Genetic Algorithms

Part 2: Shortest Routing Model and Applications

Part 3. Minimum Spanning Models

Part 4: Bicriteria MXF/MCF Model

Part 5: Capacitated QoS Network Model

◈ Title : 3D Sound Research at Virtual Audio Systems Laboratory (NRL 2005~2010)
◈ Speaker : Prof. Youngjin Park (KAIST)
◈ Date & Time : Friday, April 15, 2011 (14:00pm ~ 15:30pm)
◈ Place : LG Research Building, Room #101
◈ Host : Prof.  Sangchul Won (Tel. 2221)
◈ Abstract : Human mainly depends on the visual and auditory cues to capture spatial information about the environment. Frequently, auditory cues are often given minimal attention in designing the virtual environment. However, auditory cues play an important role in production of the virtual environment because spatial information provided by vision only is limited only to the viewing direction. The ability to identify the location of a sound source is called auditory localization and technologies that replicate the sounds from a real environment through an artificially created environment based on human’s auditory localization are known as 3D sound technology. Virtual Audio Systems Laboratory (VASL) at KAIST has been studying 3D sound technology and its applications. In this seminar, we overview the research activities of VASL related to 3D sound technology. There are two main topics in this seminar. The one is the high-fidelity Virtual Auditory Display (VAD) system which generates spatial virtual sounds in 3D space and conveys them to a listener without measurement of the individual Head-Related Transfer Functions (HRTFs). The second one is the robot auditory system in which sound source localization   is possible to achieve the effective human-robot interaction. The developed high-fidelity VAD system can be easily applied to many practical application fields including games, home theatre, virtual reality, and military simulator, etc. The developed robot auditory system, which includes artificial ear, MEMS sensor, SoC for sound localization and speaker/speech recognition, can be used for intelligent robots to process speech/acoustic signals. On going research topics in the laboratory including an idea of auditory system for hologram are introduced as well.
