Accessibility to healthy and nutritious foods is a crucial factor for public health outcome. This paper proposed a store square footage-to-population ratio as indicator of spatial accessibility to food stores. An enhanced floating catchment area method is used to compute the store footage-to-population ratio. The method adopts the Huff Model to model the people's selection on food stores and consider...
Growing peak demand has necessitated the introduction of Time-of-Use (TOU) pricing to Demand Side Management (DSM) in order to cause some peak demand to be shifted from peak to off-peak periods. Therefore, in this work, a Daily Maximum Energy Scheduling (DMES) — DSM technique is proposed. The DMES-DSM device is proposed to be installed into consumers' smart meters and schedule energy consumption for...
As a financial service, microcredit has solved the long-lasting problem that the formal financial institutions cannot provide a valid and effective way for the poor people to satisfy their financial demand. In this paper, an empirical study was made with the statistics data of Qingdao in China to measure the implementation of microcredit. Multiple linear regression models are established on both total...
Based on the data of household income of Shanghai low-rent housing families, a GM(1,1) forecast model and a Back-Propagation Artificial Neural Network (BPANN) forecast model are established respectively to predict the average household income of low-rent housing families. The comparison between the GM(1,1) and the BPANN model showed that the BPANN model is better than the GM(1,1) model at the aspects...
This article finds that there are four main reasons which are shopping environment, perceived convenience, merchandise awareness and service evaluation influence patronage of supermarkets' consumers in China by analysis of questionnaire and analyzes on the similarities and differences of different characteristics of demography.

In terms of housing issues, the primary focus of economists has been the ratio of housing price to income. Argument about its applicability has not held up. Entropy weight and optimal point approach is employed to evaluate household housing purchasing power by income classes in this article. Entropy weight is more prominent in expressing the impact of the factor than subjective weight. Optimal point...
In this paper, we describe our study on enrollment prediction using support vector machines and rule-based predictive models. The goal is to predict the total enrollment headcount that is composed of new (freshman and transfer), continued and returned students. The proposed approach builds predictive models for new, continued and returned students, respectively first, and then aggregates their predictive...
