With the rapid development of EVs (electric vehicles), the integration of PV (photovoltaic) generation with EV charging infrastructure can effectively improve the efficiency of clean energy utilization and carbon emission reduction. How to optimize the capacities of components in the PV-based...

Macroeconomic fluctuations affect corporations' performance through demand and cost conditions. Incentive effects of performance-based compensation schemes for management may be weakened or biased by macroeconomic influences if management is unable to forecast macroeconomic fluctuations or...

To measure the propulsive performance of a high-frequency PDRE (pulse detonation rocket engine), an experimental facility was established. Utilizing the valveless mode, the PDRE was operated without the purge process at a maximum operating frequency of 110 Hz successfully. In this study,...

In traditional PDRE (pulse detonation rocket engines), mechanical valves are used for periodic supply control and a purge process is widely used to form a buffer zone to prevent fresh fuel-oxidizer mixture from pre-ignition. However, both of them increase hardware complexity and limit increase...

A corer, which can obtain long <i>in situ </i>pressure-retained sediments of up to 30 m core containing gas hydrates, has been applied in the South China Sea (SCS) dozens of times. The corer presented in this paper is a convenient, efficient and economical long <i>in situ </i>pressure-retained coring and...

Purpose– This study aims to propose the idea of which macro-factors and how the macro-factors impact on the gold price. Design/methodology/approach– An EGARCH model is applied to test the volatility of gold price. A VAR method is applied to validate the idea by decomposing gold's value into...

Based on the Density Functional Theory (DFT) with noncollinear-magnetism formulations, we have calculated the magnetism of single 3d transition-metal atoms and the magnetic anisotropies of supported Ni chains on the Au(110)-(1 × 2) surface. Our results for single absorbed 3d transition-metal...

The U.S. personal bankruptcy system functions as a bankruptcy system for small businesses as well as consumers, because debts of noncorporate firms are personal liabilities of the firms' owners. If the firm fails, the owner has an incentive to file for bankruptcy, since both business debts and...
