Passive fuzzy controller design for nonlinear systems with multiplicative noises

This paper proposes a passive fuzzy controller design methodology for nonlinear system with multiplicative noises. Applying the Itô's formula and the sense of mean square, the sufficient conditions are developed to analyze the stability and to design the controller for stochastic nonlinear systems which are represented by the Takagi-Sugeno (T-S) fuzzy models. The sufficient conditions derived in this paper belong to the Linear Matrix Inequality (LMI) forms which can be solved by the convex optimal programming algorithm. Besides, the passivity theory is applied to discuss the effect of external disturbance on system. Finally, some numerical simulation examples are provided to demonstrate the applications of the proposed fuzzy controller design technique.

互逆真蕴涵的建立过程为何要这样定义

互逆主义逻辑中的互逆真蕴涵的建立过程与经典逻辑中的实质蕴涵的定义一样,都是三真一假的真值表,但含义却不尽相同。     

Investigating the effects of furloughing public school teachers on juvenile crime in Hawaii

Policymakers have long been concerned about the large social costs of juvenile crime. Detecting the causes of juvenile crime is an important educational policy concern as many of these crimes happen during the school day. In the 2009–10 school year, the State of Hawaii responded to fiscal strains by furloughing all school teachers employed by the Department of Education and canceling classes for seventeen instructional days. We examine the effects of these non-holiday school closure days to draw conclusions about the relationship between time in school and juvenile arrests in the State of Hawaii on the island of Oahu. We calculate marginal effects from a negative binomial model and find that time off from school is associated with significantly fewer juvenile assault and drug-related arrests, although there are no changes in other types of crimes, such as burglaries. The declines in arrests for assaults are the most pronounced in poorer regions of the island while the decline in drug-related arrests is larger in the relatively more prosperous regions.     

关于或有事项若干问题的分析

或有事项作为特殊的不确定性事项，是不确定性会计的重要内容。或有事项的确认和披露是当前会计理论和实务中的一大难点。要正确理解和运用财政部发布的《企业会计准则——或有事项》，必须明确或有事项与未来事项、估计事项及资产负债表日后事项的区别；正确理解负债、预计负债和或有负债之间的关系；正确区分或有事项的各种可能性及其会计处理；正确核算因或有事项确认的负债及相关的资产。     

＂-わりに（は）＂构句时的句式特征

“-わりに（は）”从语法意义上说,表示逆接,可以解释为“虽然……但是……”,但其在构句时,则带有一定的句式特征,从而将它与其他语法意义相似的句型区分开来。本文拟从基本义的角度、前接词的词性特征的角度、前后项是否为同一主体的角度及语感特征的角度来阐述“-わりに（は）”的句式特征：其前接词可以量化,强调前后项成反比关系;前后项可以是同一主体,也可以是不同主体;体现差距感。
