This paper proposes and discusses a novel AC/DC converter suitable for small-scaled wind power generation system applications. By introducing flyback cells into the three-phase single-switch Boost circuit, the proposed converter is designed as single-stage and has both rectification and high...

Rapid phase change of hydrate with high gas storage capacity is very important for the application of natural gas hydrates technology. Three pieces of open-cell copper foam (CF) with different pore densities (or pores per inch, PPI) herein were immersed in sodium dodecyl sulfate (SDS) solution...

Abstract: One of the major issues in flow assurance includes pipeline plugging due to gas hydrate formation and deposition,which makes it imperative to look for appropriate hydrate control strategies. In this study, a high-pressure visual flow loop was used to analyze the influence of different...

This paper explores the core principles that should guide the construction and governance of identity in the metaverse and identifies the critical challenges that need to be addressed. Drawing on multidisciplinary theories and perspectives, we propose two core principles for metaverse identity:...

The purpose of this paper is to present a computable general equilibrium (CGE) model of the Chinese economy which includes rigid wage-setting and integration of real and financial sectors, and to apply it to a quantitative evaluation of the oil price changes and the fiscal and monetary policies....

Fe nanowire arrays were fabricated at lower voltage by alternating current (AC) electrodeposition into the highly ordered nanoholes of the porous alumina membrane (PAM) obtained by two-step anodization in oxalic acid. The morphology, structure and magnetic properties of Fe nanowire arrays were...

This paper attempts to make use of a Copula-based GARCH (Generalized AutoRegressive Conditional Heteroskedasticity) Model to find out the relationships between the volatility of rubber futures returns in the Agricultural Futures Exchange of Thailand (AFET) and other four main markets, namely,...

In order to reduce the cost of thermal energy recovery, a packed bed closed loop thermal energy storage system has been proposed and is investigated. The main components of the system include a closed air cycle, a heat exchanger, and a packed bed storage column. This paper is aimed at analyzing...

Based on raw milk DHI data of Chinese Holstein cattle in northern China, milk composition (milk protein percentage and milk fat percentage) of lactating cow is grouped into parity 1 to 4. After preprocessing original data, 6114 data records of milk protein percentage and 5871 data records of...
