Future generation expansion has significant impact on transmission expansion planning, the paper proposes a mathematical model for multi-scenario generation and transmission expansion planning (MGTEP). This model is formulated for mixed integer linear programming (MILP) by the approach of disjunctive direct current power flow of existing and candidate lines, thus it can be solved by mature optimization...
The purpose of this paper is to propose a new design optimization technique based on flow computing and Morse theory. The basic idea is based on previous works by the authors on evolutionary architecture paradigm of evolving architectural form. Models will evolve according to a descending flow. Mathematical models include analytical functions, parametric functions and other nonlinear functions will...
Recently, using maximum likelihood linear regression (MLLR) transforms as the features for SVM based speaker recognition has been proposed. This can achieve performance comparable to that obtained with state-of-the-art approaches. In this paper, we focus on calculating the transforms based on a GMM universal background model (UBM). Rather than estimating the transforms using maximum likelihood criterion,...
Modern lifestyles have increased the risk of suffering some kind of voice disorders. It is estimated that nearly 19% of the population have suffered from dysphonic voicing. It is very important to detect pathological voices automatically. Many classification methods have been used to detect the pathological voices automatically and got good results. In this paper, we focus on the automatic detection...
The simulation of the submarine battery charge process is an important part of the submarine battery modeling, which is especially a firm foundation for the further optimization usage of the modules of the whole submarine power system. In this paper, the modeling strategy of the submarine battery charge process is discussed in detail firstly, in succession an integrated algorithm in which both the...
Unlike the traditional paper-and-pencil tests, computer adaptive testing (CAT) presents the next item based on his or her past responses, which is more appropriate for a particular individual. However, it is rarely seen in a smaller-scale scenario, such as in classrooms or business, because of the complexity of Item Response Theory (IRT) and the possible usages of services may not be known or may...
Ability level of learner is the important dimension of adaptation in adaptive learning system. There are great differences in the capacity dimensions between different learners. Even for each specific learner, his ability level changes in the learning process. In order to more effectively evaluate the learner's ability level and to support the personalized learning, we integrate the computerized adaptive...
