The cold spraying process is analyzed by numerical modeling of the impact between a single spherical particle and a substrate; the effects of impact velocity and spray angle of a particle on the particle and substrate deformation behavior were investigated. It was found that much localized...

The Doha ministerial declaration commits industrialised countries to liberalising access for least-developed countries (LDCs) to their markets. Preferential trade policies have diverse impacts on the initiating country and its trading partners. These effects are of concern to scholars and policy...

We calibrate an infinite-horizon model with endogenous growth and unemployment on actual data from the largest countries in the European Union. Two types of balanced-budget fiscal policy experiments are studied. First, the effects of separately changing the tax rates on capital, labor and...

The Earth-Air Heat Exchanger (EAHE) is a device used to improve the thermal condition of built environments, allowing the reduction of electrical energy consumption of traditional air conditioner systems. Fundamentally, its operational principle is based on fluid mechanics and heat transfer,...

This study presents a novel performance evaluation algorithm for horizontal GCHPs (ground coupled heat pump systems) that considers rainfall infiltration. The influence of rainfall infiltration on the thermal characteristics of shallow trenches is examined using infiltration analyses, and then a...

The requirements for improvement in the energy efficiency of buildings, mandatory in many EU countries, entail a high level of thermal insulation of the building envelope. In recent years, super-insulation materials with very low thermal conductivity have been developed. These materials provide...

Рассматривается проблема оптимизации режимов лазерного спекания ультрадисперсных металлических порошков, характеризуемая нестационарным теплопереносом в...

Rock salt in China is primarily bedded salt, usually composed of many thin salt layers and interlayers (e.g. anhydrite, mudstone, and glauberite). Thus, the feasibility analysis of abandoned salt caverns located in salt beds to be used as Underground Gas Storage (UGS) facilities is full of...

We examine the impact of proposed changes in US legislation to allow greater use of concentrated dairy products when producing fresh milk commodities. Although this change will allow dairy producers to partially circumvent high tariff-rate quotas (TRQs) for fresh milk products, changes in dairy...

In this paper, the feasibility of generating electricity from EGS (enhanced geothermal systems) by oilfield produced water circulating through reservoir stimulated by staged fracturing technology for horizontal wells is investigated based on the geological data of Xujiaweizi area, located in the...
