고속 전철 도입이나 대우 자동차 매각 같은 대규모의 B2B 거래에는 엄청나게 다양한 변수와 혼돈 요소가 직접 흑은 간접적으로 작용한다 소위 복잡계로 묘사되는 이런 유형의 도메인에 대하여 효율적인 정보처리가 가능하기 위해서는 인간의 묵시적 정보 처리 능력과 에이전트의 명시적 정보 처리 능력이 효율적으로 결합될 수 있어야 한다. 본 논문에서는, 이 두 가지 이질적 능력의 결합을 가능케 하는 결합 모델을 제안하였으며, 제안된 모델이 대표적 복잡계의 하나인 B2B 협상에서 어떻게 사용될 수 있는지를 보였다.

이동 데이터베이스 체계는 이동 전산처리 환경에서 데이터베이스 체계를 기반으로한 정보처리이다. 이동 데이터베이스 체계에서 이동 거래 호스트가 거래를 처리하는 동안 다른 신호영역으로 이동할 때 새로운 데이터베이스 서버에 통신망 주소로 변경해야한다. 이러한 것을 거래 서비스 통화채널 변경이라고 한다. 본 논문에서는 이동 데이터베이스 체계에서 이러한 거래 서비스 통화채널 변경의 적당한 기능을 제공하기 위한 거래처리 기법을 제안한다 이 기법은 거래 처리 서비스 통화채널이 발생할 때 새로운 데이터베이스 서버에서거래를 처리하자는 조정자 이주 원리를 적용하였다. 결국, 제안된 기법은 이동 데이터베이스에 거래를 처리하기 위한 메시지 이동을 최소화함으로서 시스템 성능을 향상시킬 수 있다.

This paper presents a reconfigurable digital signal processing(rDSP) architecture that is effective for implementing adaptive digital signal processing in the applications of smart health care system. This rDSP architecture employs an evolution capability of FIR filters using genetic algorithm. Parallel genetic algorithm based rDSP architecture evolves FIR filters to explore optimal configuration of filter combination, associated parameters, and structure of feature space adaptively to noisy environments for an adaptive signal processing. The proposed DSP architecture is implemented using Xilinx Virtex4 FPGA device and SMIC 0.18um CMOS Technology.

The purpose of this paper is two-fold: 1) A novel algorithm in order to extract lane-related information from road images is presented; 2) Design specifications of an image processing onboard unit capable of extracting lane­related information in real-time is also presented. Obtaining precise information from road images requires many features due to the effects of noise that eventually leads to long processing time. By exploiting a FPGA and DSP, we solve the problem of real-time processing. Due to the fact that image processing of road images relies largely on edge features, the FPGA is adopted in the hardware design. The schematic configuration of the FPGA is optimized in order to perform 3 $\times$ 3 Sobel edge extraction. The DSP carries out high-level image processing of recognition, decision, estimation, etc. The proposed algorithm uses edge features to define an Edge Distribution Function (EDF), which is a histogram of edge magnitude with respect to the edge orientation angle. The EDF enables the edge-related information and lane-related to be connected. The performance of the proposed system is verified through the extraction of lane-related information. The experimental results show the robustness of the proposed algorithm and a processing speed of more than 25 frames per second, which is considered quite successful.

A RMON agent system, which locates on a subnet, collects the network traffic information for management by retrieving and analyzing all of the packets on the subnet. The RMON agent system can miss some packets due to the high packet analyzing overhead when the number of packets on the subnet is huge. In this paper, we have developed a light-weight RMON agent system that can handle a large amount of packets without packet loss. Our RMON agent system has also been designed such that its functionality can be added dynamically when needed. To demonstrate the dynamic reconfiguration capability of our RMON agent system, a simple port scanning attack detection module is added to the RMON agent system. We have also evaluated the performance of our RMON agent system on a large network that has a huge traffic. The test result has shown our RMON agent system can analyze the network packets without packet loss.

The sound source localization system is used to some area such as robotic system, object localization system, guarding system and medicine. So time delay estimation and angle estimation of sound direction are studied until now. These days time delay estimation is described in LabVIEW which is used to create innovative computer-based product and deploy measurement and control systems. In this paper, the development of signal monitoring platform is presented for sound source localization. This platform is designed in virtual instrument program and implemented in two stages. In first stage, data acquisition system is proposed and designed to analyze time delay estimation using cross correlation. In second stage, data obtaining system which is applied and designed to monitor analog signal processing is proposed.

As the use of Internet being generalized, ordering system can be easily achieved on the Web so that the direct sailing system is replaced the various types of Built-To-Order system. It is important to give the up-to-date information to the end-user in order to build the Built-To-Order system. Recently, the way of providing information is updating the product related information continuously. In this study, we provide the method that can be streamlined Product Data Management System which manages a creation and update for product information into the direct BTO system in order to achieve the newest information. This methodology is not only transferring the information but also processing the information in an appropriate form. So this paper is going to cover the various point of view of information processing.

This paper proposes a policy adjuster-driven Grid workflow management system for collaborative healthcare platform, which supports collaborative heart disease diagnosis applications. To select policies according to service level agreement of users and dynamic resource status, we devised a policy adjuster to handle workflow management polices and resource management policies using policy decision scheme. We implemented this new architecture with workflow management functions based on policy quorum based resource management system for providing poincare geometrycharacterized ECG analysis and virtual heart simulation service. To evaluate our proposed system, we executed a heart disease identification application in our system and compared the performance to that of the general workflow system and PQRM system under different types of SLA.

Text-to-Speech 시스템에서 자연스럽게 음성을 합성하기 위해서는 운율과 길이 에 대한 처리가 선행되어야 한다. 이를 위해서, 자연어 처리에 의해 분석된 문장들에 대해 억양 규칙을 적용한 후, 반복적인 실험을 통해 운율 및 길이 정보를 추출하였다. 본 논문에서는 이러한 정보를 이용하여 Text-to-Speech 시스템에서 자연성을 향상 시 킬 수 있는 방법을 제안한다. 실험 결과, 본 논문에서 제안하고 구현한 무제한 Text- to-Speech 시스템이 이러한 정보들을 사용하지 않는 시스템과 비교해서 더 자연스럽게 문장들을 합성해 낸다는 것을 보였다.
