Here the experimental technique for measuring the thermal conductivity of nanofluids at the temperatures above 100 °C has been developed, and a systematic research on the thermodynamic properties including thermal conductivity, viscosity, specific heat and density, of the graphene-dispersed...

Hydropower development has significant impacts on the society and community economically, environmentally and socially. These impacts may go beyond the regional level, even across the nation. As one of the largest scale hydropower developments in the world, the Three Gorges Project has attracted...

Effective spatial planning is crucial for cost-effectively and sustainably developing biomass energy resources due to the diffuse nature of biomass and high transportation cost. Using the spatial analysis technology, economic models and scenario analysis, this paper presents a spatial planning...

In this paper, we develop new formulations for the locomotive planning problem (LPP) which is one of the most important railroad optimization problems. The objective of the LPP is to assign a consist (a set of locomotives) to each train in a pre-planned train schedule so as to provide sufficient...

Flow characteristics and heat transfer performances of rectangular dimpled channels with secondary protrusions are numerically analyzed and compared in this research work. The special arrangement is a conventional dimpled cavity with a small-size secondary protrusion placed upstream of the...

Purpose The purpose of this study is that on the basis of the competitive edge theory, source mechanism and evaluation approaches of industrial cluster competitiveness, combined with international trends in the automobile industry and the features of Chinese automobile industrial cluster...

Data envelopment analysis (DEA) has been widely applied to address various decision analysis problems due to its usefulness in evaluating multi‐criterion systems and providing improvement targets for such systems. A supplier selection problem is inherently a multi‐criterion decision problem,...
