Uniform Distribution, Distance and Expectation Problems for Geometric Features Processing

Complex geometric features such as oriented points, lines or 3D frames are increasingly used in image processing and computer vision. However, processing these geometric features is far more difficult than processing points, and a number of paradoxes can arise. We establish in this article the basic mathematical framework required to avoid them and analyze more specifically three basic problems: (1) what is a random distribution of features, (2) how to define a distance between features, (3) and what is the “mean feature” of a number of feature measurements? We insist on the importance of an invariance hypothesis for these definitions relative to a group of transformations that models the different possible data acquisitions. We develop general methods to solve these three problems and illustrate them with 3D frame features under rigid transformations. The first problem has a direct application in the computation of the prior probability of a false match in classical model-based object recognition algorithms. We also present experimental results of the two other problems for the statistical analysis of anatomical features automatically extracted from 24 three-dimensional images of a single patient's head. These experiments successfully confirm the importance of the rigorous requirements presented in this article.     

石泉水库主汛期拦蓄洪尾超蓄运用的风险分析

针对水资源匮乏和汛期水库大量弃水的矛盾，提出了有效的解决途径——汛期通过适时拦蓄洪尾超蓄运用的方式来充分利用洪水资源。拦蓄洪尾超蓄运用存在一定的风险，本文就超蓄运用的风险因素进行了识别分析，并从水文频率分析角度提出了计算超蓄风险率的方法；通过对石泉水库不同超蓄水位的风险率进行计算，结合可接受风险率值，得出了该水库拦蓄洪尾超蓄运用的期望水位。

试论我党对所有制结构理论的探索与创新

多年来,我党在不断深化对社会主义认识的基础上,对传统所有制结构理论进行了大胆的探索与创新,丰富和发展了马克思主义关于所有制问题的理论.党的十六大在此基础上进一步强调,要把坚持公有制的主体地位和促进非公有制经济发展统一于社会主义现代化建设的进程中.同时提出理顺收入分配关系,"完善保护私人财产的法律制度".显示了党和政府坚持现阶段"基本经济制度"这一政策的长期性、连续性和稳定性.对引导我国多种所有制经济的健康发展,必然产生深远影响.

收入不确定性对山东省城镇居民消费影响的实证分析

预防性储蓄理论认为不确定性对居民消费有负效应。本文利用《山东省统计年鉴》的有关数据对收入不确定性与我省居民消费的关系进行了经济计量分析，实证结果表明：来自收入分配差距的不确定性感受对消费有显著负效应，并且来自收入分配差距的不确定性感受比来自收入增长率波动的不确定性感受对山东省城镇居民消费的影响大，因此，缩小收分配差距是刺激消费的一项重要措施。     

The Relations Between Contextual Risk, Earned Income, and the School Adjustment of Children From Economically Disadvantaged Families.

This longitudinal study examined the relations between multiple risk indexes representing contextual adversity, income-to-needs ratios, and the elementary school adjustment of children from economically disadvantaged families. The results provide evidence for volatility in family circumstances over 2-year intervals from preschool to 5th grade, for relations between the contextual risk indexes and change in externalizing behavior, and for relations between the income-to-needs ratios and change in academic competence. The results also show differences in the timing of the effects. Little evidence was found for persistence effects. Theoretical implications concern conceptualizations of the diverse and dynamic nature of the family circumstances experienced by disadvantaged children.

基于多场景风险分析的含风电互联电网机组组合策略研究

为保证电力系统可靠运行,日前机组组合应考虑电网中不确定性因素所带来的风险。大规模风电并网给电力系统运行引入了更多的不确定性,电网互联一定程度上可削弱风电不确定性对电网运行的影响,但同时也增大了日前机组组合问题的复杂度。为了在有限的计算时间内获取计及风险的可行的机组组合方案,需要筛选典型场景来衡量电网运行风险。在风电、负荷预测误差的基础上设置了互联电网机组、联络线强迫停运场景集,构建了互联电网弃风电量期望（expected wind power curtailed,EWPC）和电量不足期望（expected energy not supplied,EENS）风险量化指标,并将其以罚函数的形式引入目标函数,建立了计及多场景运行风险的多区域互联电网安全约束机组组合模型,经两区域12节点系统验证了机组组合策略的正确性和有效性。     

Evaluating the effect of ration composition on income over feed cost and milk yield

Feed is generally the greatest expense for milk production. With volatility in feed and milk markets, income over feed cost (IOFC) is a more advantageous measure of profit than simply feed cost per cow. The objective of this study was to evaluate the effects of ration cost and ingredient composition on IOFC and milk yield. The Pennsylvania State Extension Dairy Team IOFC tool (http://extension.psu.edu/animals/dairy/business-management/financial-tools/income-over-feed-cost/introduction-to-iofc) was used to collect data from 95 Pennsylvania lactating dairy cow herds from 2009 to 2012 and to determine the IOFC per cow per day. The data collected included average milk yield, milk income, purchased feed cost, ration ingredients, ingredient cost per ton, and amount of each ingredient fed. Feed costs for home-raised feeds for each ration were based on market values rather than on-farm cost. Actual costs were used for purchased feed for each ration. Mean lactating herd size was 170 ± 10.5 and daily milk yield per cow was 31.7 ± 0.19 kg. The mean IOFC was $7.71 ± $1.01 cost per cow, ranging from −$0.33 in March 2009 to $16.60 in September 2011. Data were analyzed using a one-way ANOVA in SPSS (IBM Corp., Armonk, NY). Values were grouped by quartiles and analyzed with all years combined as well as by individual year. Purchased feed cost per cow per day averaged $3.16 ± $1.07 for 2009 to 2012. For 2009 to 2012 combined, milk yield and IOFC did not differ with purchased feed cost. Intermediate levels (quartiles 2 and 3) of forage cost per cow per day between $1.45 and $1.97 per cow per day resulted in the greatest average IOFC of $8.19 and the greatest average milk yield of 32.3 kg. Total feed costs in the fourth quartile ($6.27 or more per cow per day) resulted in the highest IOFC. Thus, minimizing feed cost per cow per day did not maximize IOFC. In 2010, the IOFC was highest at $8.09 for dairies that fed 1 or more commodity by-products. Results of the study indicated that intermediate levels of forage cost and higher levels of total feed cost per cow per day resulted in both higher milk yield and higher IOFC. This suggests that optimal ration formulation rather than least cost strategies may be key to increasing milk yield and IOFC, and that profit margin may be affected more by quality of the feed rather than the cost.
