This article takes the low permeability coal seam in the coalfield of South Judger Basin in Xinjiang, as a research object.The pore structure characteristics of coal rock mass in low permeability coal seam were analyzed quantitatively using scanning electron microscopy (SEM) through the methods of statistics and digital image analysis.Based on the
Objective: We elucidated active cortical areas and their time courses during simple calculation by using whole-scalp magnetoencephalography.Methods: Twelve healthy volunteers were asked to view meaningless figures (figure viewing) or digits (digit viewing) and add single digits (calculation).The magnetic signals of the brain were measured using a h
For permanent magnet synchronous motors (PMSMs) supplied Conditioner with a voltage source inverter, current control strategies are commonly implemented under the synchronously rotating reference frame.In order to simplify the system structure, three-phase currents can be measured with a single DC-link current sensor using the phase current reconst
The core mechanism of Advanced Orbit System (AOS) mainly contains the packet channel multiplexing and the virtual channel multiplexing.The multiplexing efficiency and frame time directly affect the performance of the AOS and even the whole system.In this paper, in order to optimize AOS multiplexing performance, a scheduling method of cross-layers o
