Recently, many research groups have focused on GPGPUs in order to improve the performance of computing systems. GPGPUs can execute general-purpose applications as well as graphics applications by using parallel GPU hardware resources. GPGPUs can process thousands of threads based on warp scheduling and CTA scheduling. In this paper, we utilize the traditional CTA scheduler to assign a various number of CTAs to SMs. According to our simulation results, increasing the number of CTAs assigned to the SM statically does not improve the performance. To solve the problem in traditional CTA scheduling schemes, we propose a new IPC-based dynamic CTA scheduling scheme. Compared to traditional CTA scheduling schemes, the proposed dynamic CTA scheduling scheme can increase the GPU performance by up to 13.1%.

In this paper, we developed a Widows 98 version off-line programming system which can simulate a track vehicle model in 3D graphics space. The track vehicle was adopted as an objective model. The interface between users and the off-line program system in the Widows 98's graphic user interface environment was also studied. The developing language is Microsoft Visual C++. Graphic libraries, OpenGL, by Silicon Graphics, Inc. were utilized for 3D Graphics.

In This paper we calculate the probabilities of binomial and Poisson distributions when n or${\mu}$ is large. Based on this calculation we consider the normal approximation to the binomial and binomial approximation to Poisson. We implement this approximation via CGI and dynamic graphs. These implementation are made available through the internet.

기대효과란 행동이 시작하기 전에 반대반향으로 일어나는 행동을 위한 준비단계로 주로 이차원 애니메이션에서 행동을 강조하기 위해 사용되어 왔다. 본 논문은 영상을 매개로 하여 인식 기반의 기대효과를 자동 생성함으로써 시청자의 주의를 임의의 정보에 집중시키는 방법을 제안한다. 이미지 기반의 집중점을 찾는 문제와 영상속의 움직임을 찾는 방법을 바탕으로 집중성 강화 알고리즘을 역으로 풀어 기대효과를 생성하는 방법을 제시한다. 주요점에 정보를 반대로 약화시키는 기대효과를 통해 주요점을 더욱 역동적으로 강조 할 수 있다. 본 논문의 알고리즘을 통해 광고 등의 전보전달을 위한 영상 또는 역동적 표현이 필요한 영상의 보정이 가능해진다.

최근 휴대용 기기의 성능이 향상되면서 다양한 형태의 메뉴 구성과, 메일 및 이차원 지도 등의 표현에 벡터 그래픽을 많이 도입하고 있다. 본 논문은 모바일 기기에서 많이 사용되고 여는 이차원 벡터의 처리 기술인 OpenVG (Open Vector Graphics)의 하드웨어 가속기를 제안했다. 제안된 하드웨어 가속기는 그래픽에서 처리가 빈번한 렌더링(rendering)의 각 기능을 분석하여 하드웨어 구현에 적합하도록 나누고, 그 알고리즘을 설계 및 검증하여 HDL (Hardware Description Language)로 FPGA (Field Programmable Gate Array)에 이식하여 구현되었으며, 알렉스 처리기에 비하여 약 4배의 빠른 처리속도를 보였다.

Partial residual plots, augmented partial residual plots and CERES plots are basic diagnostic tools for dealing with curvature as a function of specific predictors in regression problem. However, it is known that these plots can miss a curve or show a false curve in some cases such as predictors are related each other. Dynamic display of these plots is developed and applied. Examples demonstrate that dynamic plots are useful for obtaining additional Information on the curvature.
