Harmful algal blooms (hereafter HABs) pose significant threats to aquatic health and environmental safety. Although satellite remote sensing can monitor HABs at a large-scale, it is always challenge achieve both high spatial temporal resolution simultaneously with single earth observation system (EOS) sensor, which much needed for environment monitoring of inland lakes. This study proposes multi-source sensing-based approach HAB in Chaohu Lake, China, integrates Terra/Aqua MODIS, Landsat 8...

Abstract Background Ticks are blood-feeding significant arthropods that can harbour various microorganisms, including pathogens pose health risks to humans and animals. Tick-symbiont microorganisms believed influence tick development, but the intricate interactions between these microbes relationships different tick-borne remain largely unexplored. Results Based on 111 pool samples presenting questing engorged statuses 752 1083 from cattle goats, which were collected in two types of...

In permanent magnet synchronous machines (PMSMs), the inductances have important influences on both steady state and dynamic performances, such as designing control strategies, predicting torque flux-weakening capabilities. However, standard procedures for inductance measurement not been established yet. This paper presents a comprehensive analysis comparative study of various off-line methods that can be used to measure based their accuracy, experimental setup complexity. These approaches...

Because of complex and harsh environments in the underground mine, localization accuracy wireless sensor network node coal mine has been greatly affected. So a new weighted centroid algorithm Mine networks based on RSSI was proposed. Based full study signal transmission attenuation model, to use for distance measurements, combine with localization. Simulation results show that improves nodes mine.

Metros are mass rapid-transit systems that have helped solve commuting problems for residents of metropolises throughout the world. However, adverse geological structures, leading to problem such as water inrush and mud gushing, pose a major threat metro construction. Geophysical survey techniques provide quick relatively inexpensive ways detect structures ahead tunnel face. Left line R3 in Qingdao, China will pass an aquifer sand layer under Wolong River. To map conditions below river, we...

A new hot stamping process with quenching and partitioning treatment is proposed in the paper. Compared to direct process, microstructures some retained austenite not only including martensite are formed according constrained carbon equilibrium (CCE) model. During tools high temperature used control (QT) between M s f , of part also implemented by prolonging holding times. In this paper, different times (partitioning times) controlled servo press, research influence time on mechanical properties.

We perform an investigation on identification of the complicated particle beam system, focusing occurrence and mechanism resonant peaks. The concept concerning dynamic effective mass system is put forward, which realizes decoupling mass, stiffness, damping. Excitation strategies, such as constant amplitude variable frequency sweep, are used during testing process. relationships between excitation recorded to study stiffness effects system. results show that variation negative main reasons...

The Taihu Lake basin is one of the fastest-growing regions in China, where natural environment has been seriously affected by humans. plant area index (PAI) an important parameter reflecting change vegetation growth, which plays a crucial role studying growth and protecting ecological environment.

Abstract Aiming at the high embankment section of heavy-load Railway, a finite element model dynamic response subgrade structure under train load is established, and ZL-TNTLM program used to apply excitation. The results show that stress on top roadbed single peak curve heavy load, value vertical acceleration vibration changes obviously presents periodic change With increase speed, pressure track bed foundation does not with but fluctuates slowly; in attenuate non-linearly along depth...

In the fast Z-pinch experiments, beam-target neutrons, Deuterium-Deuterium neutrons and Deuterium-Tritium can be generated. It is a good idea to use deuterium plasmas generate fusion which used in fusion-fission breeders. The common design of apparatuses was introduced. for breeders proposed.

Owing to its high energy efficiency, color rendering and long life, LED lamps are promising in the field of Lighting. However, it is much more important design a secondary optical lens for obtain good output efficiency light distribution pattern than lamps. In auto lamps, has advantages traditional this paper, we proposed developed blueprint taillights. A quasi free surface based on cone taillights was designed desired illumination achieved. We present procedure lens. The simulation...

The paper presents a new approach to assess the insulation condition of capacitive equipment based on power loss density. Power angle is an important parameter evaluate equipment, but it cannot represent actual without considering its capacitance and volume. In paper, through listing some engineering cases theoretical analysis, calculated under different applied voltage converted corresponding density per unit volume which normalize operation voltage, equipment. By analyzing density,...

Surface cover degree, monthly variation of topsoil water content, loss soil and nutrient in alfalfa-corn intercropping, strip rotation cropping corn monoculture were studied this paper.
