The varying coefficient model is widely used as an extension of the linear regression model. Many procedures have been developed for the model estimation, and recently efficient variable selection procedures for the varying coefficient model have been proposed as well. However, those variable...

Passive solar house can improve indoor thermal comfort, but produce the problems of overheating in summer and inconvenient for operation. To solve the existing problems, solar wall with color changed was proposed and a full-scale experimental house with color changed was built in Dalian. Thermal...

Extended exergy appears to be the only currently available second-law based and unified metric for ecological accounting, and it represents an effective measure of the technical, social and environmental impacts associated with the general “operation” of a complex society. The method of...

Modeling conditional distributions in time series has attracted increasing attention in economics and finance. We develop a new class of generalized Cramer–von Mises (GCM) specification tests for time series conditional distribution models using a novel approach, which embeds the empirical...

Oil security has become a major issue in China. This paper analyzes China’s oil security from the supply chain perspective, as the country faces challenges from an increasing reliance on imported oil, a fast-growing economy, the Malacca dilemma, and volatile international oil prices. To...

Energy security usually considers both the stability of energy supply and security of energy use and it is receiving increasing attention globally. Considering the strategic importance and sensitivity to international change of the crude oil supply, we decided to examine China’s energy...

Biogas-linked agro-ecosystems provide economic and environmental benefits by using resources in a multipurpose manner. They utilize an energy consumption pattern that has prominent advantages in relieving energy shortages and reducing environmental pollution. To better understand the effects of...

In this paper, we consider an inventory–routing problem (IRP) in a large petroleum and petrochemical enterprise group. Compared to many other IRPs, the problem in this paper includes some special aspects due to the operational constraints, such as hours-of-service regulations of the company...

Based on the logarithmic mean Divisia index (LMDI) approach, this paper presents a decomposition analysis of China’s energy-related industrial CO₂ emissions from 1985 to 2007, as well as a comparative analysis of differential influences of various factors on six sectors. Via the decomposition,...

The concept of the smart grid has been gaining more and more attention worldwide since it was proposed by the U.S. Electric Power Research Institute in 2001. Recently, it has been propelled again by the promotion of low carbon economies in developing countries. To satisfy the exponential...
