Digital technology has transformed agriculture by changing traditional production methods and resource allocation. This paper investigates how agricultural digitization affects land productivity, based on farm household data. Findings indicate that significantly enhances with results remaining robust under sensitivity endogeneity tests. Heterogeneity analysis reveals the positive effects are more pronounced for larger landholdings, lower levels of human capital, older farming populations....

Abstract In this article, the lateral path following problem of unmanned ground vehicle with bounded disturbances is studied. A dual‐mode model predictive control (MPC) algorithm based on adaptive event triggered mechanism proposed. Compared existing MPC algorithm, (AEMPC) can ensure tracking accuracy and reduce optimization computation. Feasibility stability AEMPC are guaranteed by constraint region parameter design. Finally, simulation results dynamics given, comparisons made.

As the root joint of whole lower limbs, pelvis trajectory decides motion virtual human walking. Most current methods simulating can work reasonably well on even terrain, but uneven these appear insufficient. This paper uses Bezier curve to simulate trajectory. We attain by using position points in middle leg supporting duration and double support phase as control points, then connecting curve. approach not only modeling normal walking also sufficient generate terrain.

Starch is one type of biomass fuel commonly used in industries, and presents catastrophic deflagration or explosion hazards when suspended the air under certain conditions. Dust accidents might be effectively inhibited by creating a gas inerting atmosphere, instead adding conventional powder inhibitors to cause cross-contamination edible starch. In this work, evolution starch flame inhibitory atmosphere N2 CO2 was investigated. The mechanisms gases were analyzed, verified summarized...

In this paper, a PID control system based on Double Radial Basis Function(RBF) neural network is proposed for time-varying systems such as 7-DOF mechanical arm. This combines the benefits of system, fuzzy well while being able to classify errors and variations keep them under control. MATLAB/SIMULINK used carry out simulation tentative The results show that can indeed make processing faster more accurate..

This paper introduces internal control quality to study litigation risk which enrich the literature of how reduce firms’ risk. use listed company data from 2000-2015 in China A-share market research affect risk, and kind influence on caused by control. By using regression model conducting endogenous test, this finds that higher quality, lower firms reducing number involving funds used lawsuit. If companies with good they can avoid many risks caught Especially for growth undeveloped market,...

In order to secure the capacity of material handling in case system failures and overcome bottleneck mass flow material,the automatic logistic was upgraded by introducing technology linking malfunction alarm with mobile phone short message service adding an emergency route for transferring.The running efficiency finished product warehouse increased optimizing scheme depoting/retrieving improving scanning retrieving.The featured high reliability stability,less down time low labor...

Scanning cigarette cases with hand-held wireless scanner in distribution station was laboursome and mistakable, the problems of low scanning efficiency high error rate were solved by setting fixed scanners on two sides a distributing conveyor combined RS-232 serial communication OPC technologies. The increased from 25 case/min to 40 case/min, percent needed be repeatedly scanned decreased 5% 0.1%.

This paper uses the China Education Tracking Panel Data (CEPS) to analyze impact of parents' migrant workers on performance compulsory education for left-behind children. The study found that have a significant negative children in education. Although income family can be improved after parents go out work, and educational is positively affected, it still not enough make up being around. also finds going work may come from pressure high expectations. When father went restraints are weakened,...

This paper studies the impact of family finance knowledge on household asset allocation through China Household Financial Survey Data (CHFS). The study found that increase in financial will significantly diversity and promote more participation markets. conclusion is still significant after being subdivided into money market capital market. In addition, this also finds purchase self-owned housing has a crowding out effect its investment education level risk appetite diversification...
