In light of the growth in vertically specialized in global trade, the present paper uses input– output tables from the World Input–Output Database to construct an environmental multi-regional input–output model to calculate the CO₂ emissions embodied in China's international trade during...

Titterington proposed a recursive parameter estimation algorithm for finite mixture models. However, due to the well known problem of singularities and multiple maximum, minimum and saddle points that are possible on the likelihood surfaces, convergence analysis has seldom been made in the past...

This paper presents a method for stability analysis of N-cell cascade step-down buck converters, which is a kind of complex nonlinear system. A nonlinear model in the form of time-variant state equations is derived, and then the loop gain describing the overall system is introduced. With the...

Thermal storage with molten salt is considered to be an important subsystem for solar thermal power stations due to the fluctuation of sunshine over time. A molten salt thermal storage tank, in which the fluid is stratified in temperature with “hot” on the upper level and “cold” in the...

In a solar thermal power tower system, a molten salt tube receiver is a significant component. However, the tube flow performance is different with other tubes, half the circumference of the tube is heated with a different heat flux and half that circumference is insulated. As the properties of...

This paper investigates the interaction between the heat transfer performance and the thermal efficiency of a molten salt receiver used in the solar power tower plant. A test-bed is built, and a series of experiments of heat transfer enhancement for two types of molten salt receiver tubes,...
