A coupled simulation method based on Monte Carlo Ray Trace (MCRT) and Finite Volume Method (FVM) is established to solve the complex coupled heat transfer problem of radiation, heat conduction and convection in parabolic trough solar collector system. A coupled grid checking method is...

General situation of ecological environment in western region is introduced, as well as its relationship with new countryside construction. Result shows that ecological conditions of western region not only play an important role in the achievement of new countryside construction in western...

Using Japanese firms that went public during the period 1998–2006, we find that independent venture capitalist-backed IPO firms are significantly younger and smaller than IPO companies backed by venture capital firms that are subsidiaries of financial institutions. IPOs backed by independent...

Many software products and information technology services are mediated by platforms. Often these platforms feature the simultaneous occurrence of both positive and negative network externalities, e.g., the most popular operating systems are the most attractive platforms for both application...

A study is presented on the characteristics of the air source heat pump (ASHP) under two kinds of typical mal-defrost phenomena. The definition of the “Mal-defrost phenomena” is put forward, and the possible origins of their occurrence are analyzed. It is concluded that the current defrost...

While technological innovations are important for many industries, take-off sales for innovative products can have long lead times due to a variety of factors. This article identifies the main parameters affecting digital camera take-off sales in the US between 2001 and 2004. The study...

We present a numerical algorithm to solve the Boltzmann equation for the electron distribution function in magnetic multilayer heterostructures with non-collinear magnetizations. The solution is based on a scattering matrix formalism for layers that are translationally invariant in plane so that...

Consumers are increasingly using online consumer reviews (OCRs) to learn about product quality. It is thus paramount for marketers to understand what makes OCRs helpful to consumers and how this evaluation affects their decisions. Dual-process theory has been adopted in this study to investigate...
