The sub-principle level is composed of many factors, which affect yield rate and risk, such as policies, interest rate, market and enterprises . finally, different fund portfolio forms the program level of the structure . it can also be regarded as a pyramid structure, with yield rate and risk value on the top, which is supported by many factors and different investment portfolio 开放式基金的价值在确定的时间和投资额下,取决于收益率及风险因素,这是基金预定目标的基本准则层,影响收益率和风险的诸多因素,如政策、利率、市场及企业等,构成了递阶层次结构的子准则层,最后,不同的基金组合构成这个结构的方案层,也可以把它看成一个金字塔型的结构,塔顶是收益率和风险值,支撑塔顶的是诸多因素和不同的投资组合,本文将顺着这个塔型,对相关因素予以自上而下的梳理和分析解剖。
So studying the theory and method of the regional land consolidation spatio-temporal collocation and project post-evaluation, quantitatively carrying throuth the regional land consolidation spatio-temporal collocation, the land consolidation pattern spacial collocation, and the land consolidation project post-evaluation has been an important and urgent task to increase the programming level of the regional land consolidation and the management level of the project decision-making, to realize the sustainable utilization of the land resources and to maintain the healthy development of our land consolidation career 因此进行区域土地整理时空配置及其项目后评价理论与方法研究,定量地进行区域土地整理目标时空配置、土地整理模式空间配置和土地整理项目后评价,已成为当前提高区域土地整理规划水平和项目决策管理水平,实现土地资源可持续利用和保持我国土地整理事业健康发展亟待解决的重要课题。
In this paper, we first rearrange the encoder structure to support complexity scalability; then a lot of high performance algorithms are used on the key time-consuming modules in coding process; next, in programming level, processors characters are considered to improve data access efficiency and processing parallelism; finally, other programming methods, such as lookup table, explicitly assemble on key modules, are used to speed up coding process 本文系统分析了mc-dpcmdct视频编码原理,从算法和实现这两方面探讨了降低视频编码复杂度的方法,首先重组了编码器结构;接着对编码过程中的关键模块进行优化。特别地,针对移动视频通信应用,本文提出了一种低复杂度的高性能运动估值算法;然后将与处理器硬件结构相关的方法引入了优化过程,提高了数据的处理并行性和访问效率;最后使用查找表或汇编优化对关键模块进行加速。
