  • IP를 재사용하기 위해서는 테스트 벤치의 작성과 인터페이스 프로토콜 변환 회로 설계 등과 같은 인터페이스 프로토콜에 관련된 작업이 필요하다. 이러한 작업의 결과물은 버스기능모델에서 버스 프로토콜 컴포넌트에 대응하는 인터페이스 프로토콜 컴포넌트를 포함한다. 본 논문에서는 재사용 될 수 있는 인터페이스 프로토콜 컴포넌트를 사용하여 인터페이스 회로를 설계하는 방법론을 제안한다. 인터페이스 프로토콜 컴포넌트는 주어진 인터페이스 포트를 통해서 오는 트랜잭션을 인식하거나 트랜잭션을 사이클 수준으로 실행시켜 준다. 트랜잭션 중심으로 인터페이스 프로토콜을 기술하는 언어를 소개하고, 이 언어로부터 인터레이스 프로토콜 컴포넌트를 합성가능한 VHDL 형태로 생성하는 방법을 설명한다. 실험결과를 통해, 인터페이스 프로토콜 컴포넌트를 이용한 인터페이스 회로 설계 방식이 그렇지 않은 설계 방식에 비하여 많은 추가 면적을 요구하지 않음을 보인다. 제안된 인터페이스 설계 방식에서는 설계자가 IP의 인터페이스 프로토콜을 상세히 이해하지 않아도, 인터페이스 프로토콜 컴포넌트를 재사용할 수 있으므로, 인터페이스 설계 시간을 줄이는데 공헌할 수 있을 것이다.

  • A component is a reusable and replaceable software module accessed through its interface. Component-based development is expected to shorten the development period, reduce maintenance costs, and improve program reusability and the interoperability of components. This paper proposes a new robot software component platform in order to support the entire process of robot software development. It consists of specifications of a component model, component authoring tool, component composer, and component execution engine. To show its feasibility, this paper presents the analysis results of the component's communication overhead, a comparison with other robotic software platforms, and applications in commercial robots.

  • A brain-computer interface(BCI) system is a communication channel which transforms a subject's thought process into command signals to control various devices. These systems use electroencephalographic signals or the neuronal activity of many single neurons. The presented study deals with an efficient analysis method of neuronal signals from a BCI System using an independent component analysis(ICA) algorithm. The BCI system was implemented to generate event signals coding movement information of the subject. To apply the ICA algorithm, we obtained the perievent histograms of neuronal signals recorded from prefrontal cortex(PFC) region during target-to-goal(TG) task trials in the BCI system. The neuronal signals were then smoothed over 5ms intervals by low-pass filtering. The matrix of smoothed signals was then rearranged such that each signal was represented as a column and each bin as a row. Each column was also normalized to have a unit variance. As a result, we verified that different patterns of the neuronal signals are dependent on the target position and predefined event signals.

  • In the paper architecture of load flow under graphic interface we mentioned that the define of graphic interface and the way of system modeling. In the view point of engineering, domain define is the step of process which is seek out the general solution. This is a base of program's structure. When making a relationship inner component, relevance and restriction are affected by data type and etc. In this process logical data is realized as a symbol. And system configuration decide that main function and extension by the analysis user's demand and requirements. Specially engineering analysis software has accuracy also through the numerical method. To represent this wee need more powerful graphical component. This helps user's accessibility. We can combine 10, numerical library and graphical component as a system element by domain definition. In this paper we will materialize as a step of implementation and decide a direction of programming. In conclusion we will see the analysis software's necessary function to make a better.

  • A scratch tester was developed to evaluate the adhesive strength at interface between thin film and substrate(silicon wafer). Under force control, the scratch tester can measure the normal and the horizontal forces simultaneously as the probe tip of the equipment approaches to the interface between thin film and substrate of wafer. The capacity of each component of force sensor is 0.1 N ∼ 100 N. In addition, the tester can detect the signal of elastic wave from AE sensor(frequency range of 900 kHz) attached to the probe tip and evaluate the bonding strength of interface. Using the developed scratch tester. the feasibility test was performed to evaluate the adhesive strength of semiconductor wafer.

  • A scratch tester was developed to evaluate the adhesive strength at interface between thin-film and substrate(silicon wafer). Under force control, the scratch tester can measure the normal and the tangential forces simultaneously as the probe tip of the equipment approaches to the interface between thin-film and substrate of wafer. The capacity of each component of force sensor is 0.1 N ${\sim}$ 100 N. In addition, the tester can detect the signal of elastic wave from AE sensor(frequency range of 900 kHz) attached to the probe tip and evaluate the bonding strength of interface.

  • The interface between two different polymers is characterized theoretically by using a model. This model is based on the assumption that the monomeric friction coefficients of the two polymers are identical but a strong function of the matrix composition. This model predicts that the concentration profiles are highly asymmetric with substantial swelling of the slower-diffusing component by the faster component. To predict the behavior of interdiffusion, three quantities are used: distance of interface Z*(t) due to the swelling, interfacial width W(t) which is most sensitive to the detailed composition profiling, and mass transport M(t) due to interdiffusion. It is found that the more dissimilar polymer pairs, the faster the movement of the interface, the quicker its interfacial width saturates to a limiting value and the slower its mass transport. These results are in qualitative agreement with some experiments.

  • The distinguished prosperity of information technologies from great progress of e-business during the last decade has unavoidably made software development for active data mining to discovery hidden predictive information regarding business trends and behavior from vary large databases. Therefore this paper develops an active mining object(ADMO) component, which provides real-time predictive information from web databases. The ADMO component is to extended ADO(ActiveX Data Object) component to active data mining component based on COM(Component Object Model) for application program interface(API). ADMO component development made use of window script component(WSC) based on XML(eXtensible Markup Language). For the purpose of investigating the application environments and the practical schemes of the ADMO component, experiments for diverse practical applications were performed in this paper. As a result, ADMO component confirmed that it could effectively extract the analytic information of classification and aggregation from vary large databases for Web services.
