In this paper, experimental investigation into the basic characteristics of solar thermal conversion using supercritical CO2 natural convection are presented. Natural circulation of supercritical fluids can be easily induced and even a small change in temperature can result in large change in...

The main purpose of this paper is to establish a signal decomposition system aiming at mixed over-voltages in power systems. In an electric power system, over-voltage presents a great threat for the system safety. Analysis and identification of over-voltages is helpful to improve the stability...

This paper proposes a simple and effective method for classification of fundamental ferroresonance, single phase-to-ground and wire breakage over-voltages. In isolated neutral networks, power frequency over-voltages due to ferroresonance, single phase-to-ground and wire breakage may exist for a...

This paper investigates the impacts of an additional online-to-store channel and spillover effect on the optimal retail channel choice of a supply chain. In the presence of spillover effect, we discuss how the chosen retail channel affects the manufacturer's profit, online retailer's profit, and...

We investigate dynamic integration and risk transmission among major global financial markets around the conflict in Russia-Ukraine by implementing the TVP-VAR frequency model. We measure connectedness for both a high and a low-frequency band. Results show that (i) the global financial system is...
