Precision planter monitoring system based on mobile communication network

IET Networks, EarlyView., 2022
Abstract Sowing is an important link in agricultural production and the basis for ensuring high yields and bumper harvests. Agriculture requires precision plows with good performance and stable work. However, the seeding process is in a completely closed state, and the operator relies mainly on experience to judge the operating state and performance of

Coefficient diagram method-based control of semi-active vehicle suspensions with performance evaluation over circular and trapezoidal speed humps at multiple speeds

Journal of Engineering and Applied Science
The occurrence of abrupt vertical excitations, such as speed bumps, complicates the suspension system’s task of balancing stability with ride comfort. This paper uses the Coefficient Diagram Method (CDM) to design a semi-active suspension controller in a

Programmable Sequential 4D Actuation in Multistable Kirigami Metamaterials

Advanced Science, EarlyView.
This study presents a modular kirigami metamaterial framework enabling programmable multistability and sequential 4D actuation. By coupling geometry‐controlled multistability with material‐dependent recovery kinetics, spatiotemporal deformation can be precisely programmed.

Enhanced engine misfire diagnosis through integration of vibration and acoustic emission signals using artificial neural networks

Journal of Engineering and Applied Science
An accurate Engine Misfire Detection diagnosis ensures the engine runs well and reduces emissions. An ANN has successfully combined vibration and acoustic emission (AE) signals to improve the detection of misfires in engines. The vibration and AE signals

How Video‐Based Information Affects Farmers' Willingness to Pay for Drone Services

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Professional service for digital technology like agricultural drones lowers transaction costs and scope thresholds for smallholders. Meanwhile, perceptual adoption barriers remain underexplored. We conduct a two‐stage choice experiment with a randomized video‐based information treatment among 384 Chinese crop farmers to measure its effect on ...

Rural Labor Supply and Economic Opportunities: Commuting, Migration, Tariffs, and Immigration

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Some rural counties remain dependent on agricultural or manufacturing jobs, but an increasing proportion have diversified economics. Rural counties also differ in their abilities to commute to an urban market characterized by higher wages and labor productivity.

Using the Kaplan–Meier Estimator to Assess the Reliability of Agricultural Machinery

Agronomy, 2022
Kaplan–Meier analyses can be used in many disciplines, e.g., agricultural engineering. Agricultural machinery and vehicles can be regarded as objects that ‘die’ because, like living creatures, they failed, although after repair they can be used until ...
