The Lancang-Mekong River Basin (LMRB) has been particularly vulnerable to serious and successive droughts during the last decades. Nevertheless, characteristics of spatiotemporal variations in meteorological drought (MD) hydrological (HD) with an emphasis on propagation have yet be thoroughly investigated. In this study, based reanalysis data, standardized precipitation index (SPI) runoff (SRI) were employed comprehensively examine evolution MD HD. Spearman rank correlation wavelet analyses...
Abstract Background Leishmania species belong to the family Trypanosomatidae and cause leishmaniasis, a geographically widespread disease that infects humans other vertebrates. This remains endemic in China. Due large geographic area complex ecological environment, taxonomic position phylogenetic relationship of Chinese isolates remain uncertain. A recent internal transcribed spacer 1 cytochrome oxidase II phylogeny has challenged some aspects their traditional taxonomy as well cladistics...
During the rough marine environment, heave compensation is used to offset motion of vessel when a crane lifts and lands load. Thus, load are realized decoupled. In previous studies, interference items such as hydraulic cylinder friction, underwater drag force nonlinear friction in active system compensated concentrated be estimated. this paper, we disassembled items; disturbance observer adaptive rate designed estimate unmodeled uncertain parameters, respectively; an compensator with cascade...
An energy extraction technology based on motion-constrained tandem oscillating hydrofoils is presented in this paper. The turbine for extracting from the flow field designed and built measured frequency performance analysis of hydrofoils. instantaneous rotating speed torque output shaft are using a meter to determine power extracted by turbine. Experimental results show that optimal reduced both single hydrofoil about 0.1 cycle-averaged efficiency with reaches 29.2%.
Wave energy is a renewable source that green, clean and has huge reserves.

On basis analysis relationship between movement characteristics and parameters including power coefficient, efficiency reduced frequency, device based on tidal current designed. The investigation undertaken over a wide range kinematic pitching amplitudes, heaving...
Abstract As a clean and renewable energy, wave energy has abundant reserves, its reasonable development utilization can effectively alleviate the problems of shortage environmental pollution. This paper proposes mechanical rectification converter. The reciprocating linear motion buoy is directly converted into rotary through ball screw. magnetic coupling force transmission system adopted to ensure sealing device. Using mechanism service life generator. In addition, dynamic model converter...
To improve the energy extraction performance of oscillating hydrofoil, lift force that acts on hydrofoil is analyzed. The pressure difference between hydrofoil‘s opposing surfaces dominant to generate force. Forming and shedding leading-edge vortex from surface determines hydrofoil. In this paper, with different chord flexibility coefficients maximum offset at trailing edge are analyzed obtain power coefficient, moment coefficient influence mechanism chord-wise deformation explored....
This study proposes a multi-mode switching control strategy based on electromagnetic hybrid suspension (EMHS) to achieve the best relationship possible between vehicle’s vibration reduction performance and energy consumption. The working modes of EMHS are divided into active, semi-active, recovery according root mean square weighted acceleration human subjective sensation. two key parameters analysis sampling interval judgment times introduced optimize conditions reduce deterioration comfort...
