This thesis uses DEA to compare the WANO's performance indicators among three nuclear power plants in Taiwan. We take the past 7 years'(1997-2003) data of 3 plants, there are 21 DMUs totally. Due to the importance of the nuclear power plant safety performance , we adopt the output estimation by assuming the input as a constant; Five outputs parameters such as unit capability factor, unplaned automatic scrams are chosen to proceed the comparison and get the relative efficiency. We also collect the WANO performance indicators data of the same type nuclear power plants as Taiwan in the United State during 1999-2003 to proceed the same comparison with the domestic three nuclear power plants , in order to understand the relative efficiency between two groups.

本文系利用数据包络分析法，针对台湾地区三座核能电厂之世界核能协会绩效指标的实绩进行实证比较，研究对象是以这三座电厂过去七年（1997--2003）来的实绩比较，每一年度为一个评估单位，共有21个DMUs，由於核能电厂安全绩效之重要性甚高，故本研究纯粹以产出项为考量的绩效评比方式，故将投入项设为常数；产出项则选取机组容量因数、非计划自动急停次数等五项参数，进行评比求出其相对效率；另外也收集了1999—2003年美国同型电厂之WANO绩效指标实绩进行比较，以了解国本国三座核能电厂相较於美国电厂之相对效率为何？

This system mainly contains the front-end pulse interception and back-end software analysis. In the first part, we used a non-invasive infrared measurement method based on the dual channel simultaneous measurement technique. We measured the photo-plethysmograph from the subject's fingers and toes simultaneously, then used an analog circuit and central control unit to process the signals. Finally, the digital volume pulse data is processed by a personal computer. Because the characteristic points of digital volume pulse always occur in sharp variations, this paper proposes two algorithms to solve this problem. First, we find the pacemaker and percussion wave peak from transient slope variation, and then locate the dicrotic notch and dicrotic wave peak by using the wavelet transformation algorithm. When we analyze the data, we use the Visual Basic graphical user interface, which together with the Matlab is the core of the system.

The algorithm is applied in the segmentation of Magnetic Resonance Imaging of human brain for the 3D reconstruction on dependent of different human tissue structures, in which the problem on wraps between different tissues and fuzzy edges between the different regions in medical volume data may better be settled, which can not be well done by the typical"hard"segmentation using binary logical representation.(3) An accelerated algorithm of volume rendering with X-ray perspective and Phong shading effect based on textures mapping and blending is presented for realizing 3D reconstruction of medical volume data by 2D texture mapping and blending, in which the accelerated algorithm of window transformation is utilized to computing voxels' gray scales and opacities to produce X-ray perspective images, and Phone illumination model is used to import world light sources and an unit spherical surface under the same shading environment as the actual volume rendering is employed to simulate the real reflectional light of per-voxel so that 3D reconstruction possesses illumination effect in the world. Furthermore, 3D matrix transformations of degree rotation and other operations of 3D object are studied, and a fast equivalent method of corresponding shading correction is brought forward to improve its interaction speed in volume rendering process.
