In this study as treating to filter silance coupling agent (KM-6030 improving coupling strength between matrix resin (bisphenole-A type epoxy resin) and filler (SiO2), breakdown strength was investigated on cases applying DC voltage to specimen. In the case on DC voltage, breakdown strength was improved bout 12.73% and 10.77% in specimen of 5[wt%] and 50[wt%] of filler content of 10 of epoxy. Therefore, it was investigate the effect that concentration of coupling agent and content of filler was influential on breakdown strength of epoxy resin.

By managing various communication networks collectively, Telecommunication Management Network (TMN) has appeared as a concept to aim for the unified and effective communication network operation and maintenance. IMT-2000 and other network such as PSTN, cellular networks and packet witching network that are integrated with IMT-2000 have been developed in different platforms - hardware and operating system, and a same circumstance will happen in the maintenance in the future. Also, it is difficult to approach to the standard for Ｑ3 interface implementation of the agent in TMN system that may occur in the development or the maintenance for the different platform of IMT-2000 and other networks that are integrated with IMT-2000. In order to solve this kind of Problems, this Paper suggests integrated network management agent of IMT-2000 based on the NTS model and Advanced Intelligent Network(AIN).

It was investigated that space charge characteristics of EPDX/LPE laminates as a function of interfacial condition. There were no effects in charge accumulation characteristics at EPDM/XLPE laminate samples which were pasted with silicone oil and silicone grease. But when the crosslinking coagent (TMPTA) was pasted in laminate samples, there was no space charge in interface of EPDE/XLPE laminate and no effects in the laminate sample pasted with silicone grease dissolved crosslinking coagent. In the coupling agent pasted EPDhyXLPE laminate sample, space charge was accunlulated in XLPE side caused by coupling agent.

In order to determine what influences the interfacial charge in EPDM/XLPE laminates, We used PEA (pulsed electroacoustic) method. Interfacial properties such as space charge accumulation and breakdown strength in crosslinked polyethylene (XLPE)/ethylene-propylene-diene monomer (EPDM) laminates were investigated. Interfacial charge develops when the EPDM is laminated with XLPE. It showed the positive polarity same as the simulation in case on intercase of EPDM/XLPE. In case of coupling agent added silicone oil, as increasing the content of coupling agent, the interfacial charge decreased. Details of the results are given and their origins discussed.

The human performance issues and increased automation issues in advanced Small Modular Reactors (SMRs) are critical to numerous stakeholders in the nuclear industry, due to the undesirable implications targeting the Man Machine Interface Systems (MMIS) complexity of (Generation IV) SMRs. It is imperative that the design of future SMRs must address these problems. Nowadays, Multi Agent Systems (MAS) are used in the industrial sector to solve multiple complex problems; therefore incorporating this technology in the proposed innovative SMR (I-SMR) design will contribute greatly in the decision making process during plant operations, also reduce the number MCR operating crew and human errors. However, it is speculated that an increased level of complexity will be introduced. Prior to achieving the objectives of this research, the tools used to analyze the system for complexity reduction, are the McCabe's Cyclomatic complexity metric and the Henry-Kafura Information Flow metric. In this research, the systems engineering approach is used to guide the engineering process of complexity reduction concept of the system in its entirety.

Purpose As artificial intelligence voice agents (AIVA) have been widely adopted in services, diverse forms of their voices, which are the main interface with users, have been experimented. The purpose of this study is to examine how users evaluate vocal characteristics (gender, voice pitch, and voice pace) of AIVA, depending on prior research on human voice attractiveness. Design/methodology/approach This study employed an experimental survey which 516 participated in. Each participant was randomly assigned into one of eight situations (e.g., male - higher pitch - faster pace) and listened a AIVA voice sample, which introduce weather information. Next, a participant answered three consequence factors (attractiveness, trust, and anthropomorphism). Findings The results reveal that female voices of AIVA were perceived as more attractive and trustworthy than male voices. As far as voice pitch goes, while lower-pitch voices were preferred in female voices, higher-pitch voices were preferred in male voices. Finally, faster voices of AIVA were more attractive than slower voices.

최근 각광 받고 있는 서버 기반 컴퓨팅(SBC, Server-based Computing)은 많은 수의 서버가 필요하기 때문에 많은 수의 서버를 관리할 수 있는 관리자 시스템의 필요성이 대두되고 있다. 이에 관리자 네트워크를 필요에 따라, 코맨드 센터(CC, Command Center), 서버 에이전트(SA, Server Agent), 관리자 인터페이스(Manager Interface), 유저 에이전트(UA, User Agent)등 네 가지 모듈로 분리하여 필요한 시스템 기능을 구현하는 것만으로 저비용으로 신뢰성 있는 네트워크를 구축할 수 있는 네트워크 프레임워크를 개발하고, 그 성능을 측정하였다.

In the past several years there has been increasing the studies using P2P technology in the distributed system areas. In these P2P systems, the server to support the contents-information have less overloads than the composed system as the server to have resources generally. In this paper, we propose the system to support a social network P2P service based on the social network P2P system. The object of this study was to widen the use of this menu system to determine the price based on visual information by a software agent. Therefore, this system is suitable for micro, small and medium industries in the use of P2P servers and is more usable system interface for owners than previous study.

This paper presents a robotic agent design and application in the ubiquitous intelligent space. We set up an experimental environment with Bluetooth host, Bluetooth client, furniture and home appliance, and robotic agents. First, the agents basically performed patrol guard to detect unexpected penetration, and to keep home safely from gas-leakage, electric leakage, and so on. They were out to patrol fur a robbery while navigating in a living room and a private room. In this task, we used an area-based action making and a hexagon-based Q-learning to control the agents. Second, the agents communicate with Bluetooth host device to access and control a home appliance. The Bluetooth host offers a manual control to person by inquiring a client robot when one would like to check some place especially. In this exercise, we organize asynchronous connection less (ACL) between the host and the client robots and control the robot maneuver by Bluetooth host controller interface (HCI).

Existing internet auction systems have adopted the form which gives a win to the auction bidder who proposes the top bid price for the goods posted on the auction board. But they haven't been satisfying the automatical one-step processing for user’s convenience because they must require continuous care of user for bidding and checking as well as neglecting the convenience of user interface while participating in the electronic bidding system. The agent push mail to a auctioneer information that able to get how much profit as calculate duration time and start price with bidding history stored database. So, this thesis propose a multi-agent system in internet auction that generate the highest margin for auctioneer’s goods.
