The Shannon entropy and quantitative time irreversibility (qTIR) are statistical quantifiers that widely used for characterizing complex processes. However, the differences associations between them have not been subjected to detailed investigation. In this Letter, we report a comparative analysis of qTIR using model series real-world heartbeats. We find permutation-based (PEn) (PYs) detect nonlinearities in differently according surrogate theory. Moreover, PEn PYs, based on either original...
Underground coal mining brings many environmental problems, which are mainly caused by mining-induced fractures. Hence, obtaining a better understanding of fissure is necessary to solve the issues. This study first uses software (PFC3D) simulate development fracture network and then adopts transient electromagnetic method (TEM) in Ganzhuang Coal Mine investigate distribution The results show that overburden strata full cracks, connect with each other, forming network. Besides, shape fissures...
Electric propulsion UAV powered by hybrid power system consisting of fuel cells and lithium batteries have attracted significant attention for long endurance zero emission. Different dynamic characteristics variable load demanding which can be stochastically affected the UAV's flight air disturbance are difficult to modeled with energy management (EMS). In this paper, a Deep Reinforcement Learning (DRL) algorithm, namely twin-delayed Deterministic policy gradient (TD3), is adopted derivate...
Owing to peak power demands of pulsed load like radar and beam weapon is much larger than capability generator, researches about energy storage equipment sizing optimization have been extensively carried out. However, these are mainly considered from static perspective without taking dynamic characteristic into consideration. To cover this gap meet strict weight requirements airborne platform, paper proposed a hybrid system process satisfy demand while standard set up by MIL-STD-704F also...
This paper proposes a novel and effective invariant shape representation by Radon stationary wavelet transforms for images with complex inner shapes. The proposed method is to general geometrical transformations. Instead of analyzing shapes directly in the spatial domain, retrieves features radon transform domain statistical spectral analysis make translation size invariant. used rotation Experiment results show that rotation, translation, and/or scaling changes shapes, outperforms other...
Abstract This paper presents a numerical modeling method that integrates grain-growth model and Voronoi polygon configuration to investigate the thermal damage characteristics fracture mechanism of granite under three distinct conditions: rapid heating, slow cycle heating. The proposed accurately simulates intra-grain modes mineral particles mechanical responses granite. Through simulation, it was observed heating induces more significant deterioration compared while leads wider crack...
Precise prediction of coal thickness is the utmost importance in realizing intelligent and unmanned mining. As channel wave characterized by an easily recognizable waveform, a long propagation distance, strong energy, it widely used for inversion. However, most traditional inversion methods are local nature, result probably not optimal global scope. This paper introduces GA-SIRT hybrid approach, which combines Genetic Algorithms (GA) Simultaneous Iterative Reconstructive Techniques (SIRT)...
Objective To observe the application effect of new nursing appliances in department ophthalmology, and to explore more safety, normative, efficient method. Methods Totally, 296 inpatients from June 2012 2013 Department Ophthalmology our hospital were randomly divided into experimental group (n=155) control (n=141). The patient applied traditional eye drops use, which nurse took medicine according doctor′s advice kept it reserved by patients, drug putted on patient′s bedside. was...
