The Analysis of the Local government tax revenue andTax Effort---------The Effect of Common Factor
地方政府的财政能力最终体现为地方政府的主观努力程度作用于客观环境的结果。但各个地方政府所处的地理位置,历史发展水平,经济发展速度,资源禀赋数量,以及政策环境不同等等差别,造成了各地方政府的主观努力程度也有所差别。在经济发展水平较高,资源禀赋数量较为丰富的地区,地方政府的主观税收努力程度不用较大也能获取到相应的支撑公共支出所需的财力。相反地,在经济较为不发达的地区,地方政府要获得相应的支撑共同支出的财力可能需要较大的主观上的努力。为了便于比较分析不同地方政府在不同条件下的主观努力程度,本文选取了相应的模型与方法,力求通过深入分析,挖掘出影响地方政府税收努力程度的因素,以及在剥离出客观环境条件的情...Financial capacity of local governments as the ultimate expression of the local government's effort to act on the results of subjective and objective environment.

Design of a Temperature-Controlled Test System for Luminous Intensity Spatial Distribution Characteristics of High Power LED
发光二极管(lEd)的光强空间分布特性决定了它能否满足特定场合的应用。大功率lEd由于发热量大,其绝对光强空间分布(lISd)的测试也必须在特定热沉温度下进行才能得到准确可靠的结果。设计了一个可对大功率lEd进行热沉温度控制且快速实现lISd自动测试的系统。该自动测试系统基于lEdgOn-100测角光度计及其高精度的二维旋转台,配合测试适配器、温度控制器、光度探头、kEITHlEy 2400源表和测试软件组成。测试软件基于dElPHI程序语言开发。在控温条件下,该lISd自动测试系统稳定可靠,测试时间大大缩短,测试结果实时直观。利用该自动测试系统对具有朗伯型和蝙蝠翼型两大lISd类型的lEd进行测试,获得它们的二维lISd和三维lISd。实验结果表明:随着热沉温度的增加,光强绝对值下降,而相对lISd却不变。Characteristics of the luminous intensity spatial distribution(LISD) of light emitting diodes(LEDs) are capable of determining whether these devices can be applied on specific occasions.The absolute LISD of high power LED can be accurately measured only when LED is fixed at a specific heat- sink temperature because of the LED′s large heat-generating capacity.In this study, an automatic test system based on LEDGON-100 goniophotometer and the meter′s high-precision two-dimensional(2D) revolving platform, is designed.In addition, it comprises of a test adapter, a temperature controller, a photometer head, a Keithley 2400 source meter, and an in-house-developed software package.This assembly can both control heat-sink temperatures and measure the LISD characteristics rapidly for high- power LEDs.The software is developed using Delphi programming language.The test system is stable and reliable.The test time is greatly reduced and measurements are instantly displayed.Two general types of LEDs, Lambertian type and batwing type, are measured by the system to obtain their 2D and three-dimensional(3D) LISDs.Experimental results show that the absolute luminous intensity decreases as the heat-sink temperature increases.However, the relative LISDs are the same under different heat-sink temperatures.国家自然科学基金(11104230); 福建省重大科技项目(2011H6025;2012H0039

Intra Prediction and Motion Estimation Algorithm Optimization of HEVC
为了进一步提高视频压缩效率,视频编码联合协作小组(JCT-VC)开发了新一代视频压缩标准——HEVC(HighEfficiencyVideoCoding)。作为最新的视频压缩标准,HEVC能够在提供相同质量的前提下,比H.264/AVC节省一半的码率。与以前的视频压缩标准相比,HEVC继承了混合编码的基本框架,同时还提供了更多高效的视频压缩工具,包括编码单元(CU)的递归式四叉树块划分结构、更多的帧内预测模式、非对称运动分割预测方式(AMP)等。这些新的编码工具在提高编码效率的同时,也极大地增加了编码器的复杂度。然而,在视频应用的诸多场合中,实时性的要求必不可少,如视频会议、视频转播、视频监控...To further improve the efficiency of video compression, Joint Collaborative Team on Video Coding (JCT-VC) has developed a new generation of video compression standard——HEVC (High Efficiency Video Coding).
