Una bomba de calor de expansión directa con energía solar (BCAES-ED) es una tecnología de calentamiento de agua con mucho potencial en países con climas tropicales y húmedos siendo relevante realizar  análisis basados en la energía y la exergía que p... see more

In 2005, Kechris, Pestov and Todorcevic provided a powerful tool to compute an invariant of topological groups known as the universal minimal flow, immediately leading to an explicit representation of this invariant in many concrete cases. More recently, ... see more

The aim of this study was the determination of the thermal expansion coefficient a (T) in relation to the temperature of the three following aluminium alloys:- Al-6%Zn-3%Mg obtained by conventional ingot casting- Al-0.5%Mg-0.88%Si obtained by Direct ... see more

In this paper, the thermodynamic performance of a direct expansion solar assisted heat pump (DX-SAHP), which is used to heat domestic water from 20°C to 45°C, is theoretically investigated. The system includes a 3m2 single-cover flat plate solar collector... see more

In an autofrettage process a given thick cylinder is subjected to such a pressure which gives a specified depth of elasto-plastic boundary. The outside diameter expansion during autofrettage process is a function of depth of autofrettage. To obtain a spec... see more

Utilization of hydrogen as an alternative fuel is promising because it is environmentally friendly. Hydrogen system design requires accurate hydrogen densities. The density of hydrogen is determined based on experimental data. For gases that have a low de... see more

In this article, we study the global acquisition trends of Chinese companies. We look at the countries and sectors they are investing in and the factors driving those investments. We consider the inflexion points and the changes before and after the Globa... see more

AbstractBackground: The South African automotive industry includes complete supply chains. The South African automotive supply chain stakeholders operating within the global arena are faced with opportunities as well as challenges. The South African gover... see more
