The generation, consumption, and transmission of distributed energy produced by a microgrid are becoming increasingly important topics in scientific research. As power source that partly relies on renewable energy, microgrids play vital role the global network. In this study, underlying principles management techniques introduced. Microgrids can reduce carbon footprint production process. This study also provides insight into how decision-makers confidently mitigate uncertainties inherent...
Abstract Adsorption plays a critical role in surface and interface processes. Fractional coverage adsorption free energy are two essential parameters of molecular adsorption. However, although at the solid–gas has been well‐studied, some models were proposed more than century ago, challenges remain for experimental investigation solid–liquid interface. Herein, we report statistical quantitative single‐molecule measurement by using break junction technique. The fractional was extracted from...

After deep study structure design engines, based Lucene tool kits we designed small-scale which can be functioned as gathering information, Chinese word segmentation, index and search, update, so on.
We study by numerical simulation the property of velocity distributions granular gases with a power-law size distribution, driven uniform heating and boundary heating. It is found that form distribution primarily controlled restitution coefficient η q, ratio between average number heatings collisions in system. Furthermore, we show can be understood as different limits q ≫ 1 ≤ 1, respectively.
