The effects of primary steam superheating on steam condensation in nozzle and the performance of steam ejector were investigated using CFD (computational fluid dynamics) method. Using a wet steam model being proposed in our previous study, simulations based on the primary steam with five...

In order to match the output capacity of a geothermal heat pump system (GHPS) with the actual load requirement, research has been carried out in finding the influence of two systematic parameters, the water flow rate inside the condenser and the compressor input frequency on the GHPS operation....

The rapid growth in coal and oil consumption has led to increasing emissions of greenhouse gases as well as air pollutants in China. In response to this, the Chinese government has begun to formulate policies to retard the increasing use of energy consumption and to improve air quality. This...

Crystal structural stability of V<Subscript>2</Subscript>O<Subscript>3</Subscript> under high pressure has been investigated by first-principles calculations. Our results demonstrate that the phase-transition sequence of V<Subscript>2</Subscript>O<Subscript>3</Subscript> is from corundum structure to Gd<Subscript>2</Subscript>S<Subscript>3</Subscript>-type structure at 30 GPa, then to the Th<Subscript>2</Subscript>S<Subscript>3</Subscript>-type structure at 52 GPa, finally to...</subscript></subscript></subscript></subscript></subscript></subscript></subscript></subscript>

The latent class model provides an important platform for jointly modeling mixed-mode data—i.e., discrete and continuous data with various parametric distributions. Multiple mixed-mode variables are used to cluster subjects into latent classes. While the mixed-mode latent class analysis is a...

Markov chains have been frequently used to characterize uncertainty in many real-world problems. Quite often, these Markov chains can be decomposed into a vector consisting of fast and slow components; these components are coupled through weak and strong interactions. The main goal of this work...
