摘要：
Radial basis function neural network (RBFNN) is an effective nonlinear learning model, which has a strong nonlinear fitting capability. The hidden neurons and the weight play important roles in the neural network. In the existing researches, the hidden neurons are computed in the form of a rigorous linear combination. And the weight is hard to be solved. To address these issues, in this paper a novel neural network named non-negative radial basis function neural network (NRBFNN) is proposed. The main thought of non-negative matrix factorization (NMF) is to be used to train the parameters of RBFNN. According to the structure of the neural network, the label information of the samples is decomposed into the weight matrix and the mapped feature by activation functions in polynomial feature space. And the proposed method is able to obtain the weight matrix and the hidden neurons implied in the activation functions iteratively. Furthermore, the proposed NRBFNN is able to improve the representability of the hidden neurons and the iterative formulas of the weight can ensure the solvability and interpretability of it. ORL, Yale and Caltech 101 face databases are selected for evaluations. Experimental results show that the proposed algorithm outperforms several related algorithms. © Published under licence by IOP Publishing Ltd.

摘要：
Based on the real-time traffic data and the isochronous circle maps which is drawn by GIS, this thesis studies the rationality ofthe configuration ofthe 35 primary schools in Furong district of Changsha city. Taking all primary schools coordinate points as the starting points, and all grid center coordinate points which are divided by GIS in whole range of the research district as the end points, the thesis extracts the travel time from starting points to end points as the basic data of the study. Considering the three modes of travel, such as walking, bus system and self-driving, the thesis draws isochronous circle maps by 10 minutes, 15 minutes, 20 minutes, 25minutes and 30minutes. And based on weightiness of different vehicles, the thesis draws the isochronous circle maps too. By analyzing the coverage of all isochronous circle maps, the thesis determines the rationality ofthe primary school. © 2017, Aracne Ed. All rights reserved.

摘要：
以长沙地区用于水源热泵的湖泊水库水体作为研究对象，建立一个湖泊水体水温计算模型，通过模型求解结果与实测数据的对比，验证了模型的正确性。利用建立的水温模型研究了长沙地区的湖泊水体水温变化规律及其影响因素，计算出长沙地区湖泊水体冷凝热与取热量热承载能力，并且对冷热承载能力的影响因素进行了分析，其结果可作为以湖泊水体为热源的水源热泵系统的设计参考。
