A standard expected value model for multi-objective multi-stage transmission planning is presented to realize the transmission optimal planning with the control of line overloading risks. In this model, a constraint of overloading risks is built with expected value and standard deviation of random line active power and two objectives are given as expected value of the average power loss and discount value of the investment cost. By modeling uncertain informations with probability theory, the probabilistic DC power flow is adopted for the correlated calculations among random variables in the planning model.4 A novel multi-objective transmission planning approach that considers transmission investment profit is proposed. Requests for transmission investment profit and social welfare are involved in the proposed planning approach.

Based on the artificial neural network model, the sensitivity analysis on each variable of model shows that the effect of ring index of diameter at breast height of Cunninghamia lanceolata on sun-spot is even, and the effects of auto-correlated factors of sun-spot on sun-spot are sensitive, which shows that three variables all have significant effects on sun-spot.

This paper aims to study some important problems of clutter modeling and simulation, which include as follow:According to the principle that each quadrature component of K-distributed clutter can be modeled, exactly or approximately, by a weighted sum of products of two independent Gaussian variables, a new method for modeling and simulation of correlated coherent K-distributed clutter is presented.

The prevalence of character limitations was significantly higher in left-behind children (64.4%) than in non-left-behind group (47.6%; x^2=21.25, P.01). The depressive symptoms score of the left-behind children was significant higher (40.4%) than that of the non left-behind group (27.8%;χ^2=13.78, P.01). Scores of EPQP and EPQN were positivey correlated with scores of CES-DC scale (r=0.198, r=0.372; P.01). Ten variables influenceing the personality traits and depressive symptoms of children were age, sex, peer interaction, parents' expectation for children, consanguineous marriage of parents satisfaction to family condition, self-estimate, academic achievement, frequency of meeting with the parents, and psychiatric history of family.
