Accessibility analysis usually requires finding the closest facility within a certain category—for example, the nearest hotel, hospital, or gas station. Along with the development of location-based services, users also wish to find the optimal route to the closest facility, based on network...

The role of urban carbon dioxide (CO2) emissions has attracted city authorities' attention. Several entities face challenges when developing inventory method for local communities, due to limited data. This study proposes a top-down method to estimate CO2 emissions at an urban scale, using...

Network routing problems generally involve multiple objectives which may conflict one another. An effective way to solve such problems is to generate a set of Pareto-optimal solutions that is small enough to be handled by a decision maker and large enough to give an overview of all possible...

Modeling land-use change is a prerequisite to understanding the complexity of land-use-change patterns. This paper presents a novel method to model urban land-use change using support-vector machines (SVMs), a new generation of machine learning algorithms used in classification and regression...

A simulation model has been developed in this paper to predict the performance of greenhouse that is heated with a heat-pipe system. The model is validated with experimental data and is found to be in close agreement. The simulation can provide estimations of the influence of the maximum height,...

In this paper, transaction cost is introduced into the general firm-level export behavior model. By so doing, we build a theoretical model explaining how connection modes between leading agribusiness enterprises and rural households affect the firm-level agricultural products export. Analyzing...

Large-scale studies of genetic variation may be helpful for understanding the genetic control mechanisms of viral infection and, ultimately, predicting and eliminating infectious disease outbreaks. We propose a new statistical model for detecting specific DNA sequence variants that are...
