The shortage of available water resources and climate change are major factors affecting agricultural irrigation. In order to improve the irrigation use efficiency, it is necessary predict requirements for crops in advance. Reference evapotranspiration (ET o ) a hypothetical standard reference crop evapotranspiration, many types artificial intelligence models have been applied ET ; However, there still few literature regarding application hybrid deep learning model parameters optimization....
We propose to develop a wide-field and ultra-high-precision photometric survey mission, temporarily named "Earth 2.0 (ET)". This mission is designed measure, for the first time, occurrence rate orbital distributions of Earth-sized planets. ET consists seven 30cm telescopes, be launched Earth-Sun's L2 point. Six these are transit telescopes with field view 500 square degrees. Staring in direction that encompasses original Kepler four continuous years, this monitoring will return tens...
Servo press has become the future development trend in field of forging equipment. Its core component is servo motor (permanent magnet synchronous motor, PMSM), and serve completely driven controlled by motor. For ideal drive transmission system advanced press, a conventional PMSM cannot do this well, so an integrated must be used. This article focuses on integration facing application background proposes novel hollow two-sided output with mechanical planetary gear. The designed based PMSM....
Reclaimed water irrigation can effectively alleviate the shortage of resources in arid and semi-arid areas; however, reclaimed contains organic pollutants that may enter agricultural production environment through irrigation, such as endogenous estrogens, so people have always paid attention to safety irrigation. In this paper, we studied effects groundwater alternating two sources on grain quality, well estrogen concentrations winter wheat topsoil North China Plain during 2015–2016. The...
With the increasing demand for astronomical observations, telescope systems are becoming increasingly complex. Thus, observatory control software needs to be more intelligent. It has each instrument inside observatory, finish observational tasks autonomously, and report information users if needed. We developed a distributed autonomous framework named Remote Autonomous Control System 2nd (RACS2) meet these requirements. Rich features integrated into RACS2 framework. The is modular framework,...
This article proposes a locally convergent, computationally efficient model predictive controller with mode switching decisions for the eco-driving problem of electric trucks. The is formulated as bi-level program where high-level optimises speed trajectory and operation implicitly, while low-level computes an explicit policy power distribution two machines. alternating direction method multipliers (ADMM) employed at to obtain optimal solution considering both optimisation integer decisions....
Usually, the conventional low-frequency vibration forming machine has a main transmission mechanism as driving source to provide force and an auxiliary generate force. The chain is long structure complex bloated, which affects process product quality. This paper presents novel mechatronics idea of machine, uses slotted tubular permanent magnet synchronous linear motor (slotted-TPMLM) both source. key that slotted-TPMLM provides sufficient accompanied with certain Consequently, this focuses...
The performance of model predictive control strategies for hybrid electric vehicles (HEVs) highly depends on the accuracy future speed predictions. This paper proposes improved prediction models deterministic (DMPC) and stochastic (SMPC), respectively. For DMPC, neural network-based predictor is first introduced taken as benchmark predictor. A novel considering historical errors proposed, which relies assumption that offset between measurement at current instant a good estimate in short...
A telescope has been an important way to observe the stars since it was invented. With development of times, people have higher and requirements for telescopes. In order further improve imaging quality observation accuracy, aperture is becoming larger larger, associated devices are more complex, working environment diverse. good control system can effectively reduce labor costs utilization efficiency time, so put forward system. The emergence computers promoted rapid a Faced with trend...
This paper aims to study the role of sentiment dispersion in stock market. We extract investor from tweets that are specifically about opinions on stocks. Naïve Bayes is then used assign each tweet a conditional probability representing how positive is. did not discretize so as reduce information loss. Sentiment measured by standard deviation. The resulting correlate with future returns and realized volatility. research able show whether contains return volatility, which helpful formulating...
The utilization of aquaculture wastewater as irrigation is an effective way to recycle and reuse water nitrogen fertilizer resources because it contains numerous nutrients.However, still unclear that the pattern substituting for supplementing conducive improving soil status, fruit yield water-fertilizer use efficiency tomato production.In this context, experiment was intended establish appropriate regime in production freshwater replacement reduction ensure good yields.Pot experiments were...
Water is the source of life. Improving and consolidating safety rural drinking water great significance to ensuring quality promoting economic development. Taking Jin Epian Drinking Safety Promotion Project in Hengxi Town Yinzhou District as an example, this paper briefly analyses design project, hoping provide experience support for development progress project. Jin'e area located upstream Reservoir, Town. The had poor filtration disinfection facilities, quantity were difficult meet...
