Greenhouses extend growing seasons in upper latitudes to provide fresh, healthy food. Costs associated with carbon-emission-intensive natural gas heating, however, limit greenhouse applications and scaling. One approach reducing heating costs is electrification by using waste heat from cryptocurrency miners. To probe this potential, a new quasi-steady state thermal model developed simulate the ...

This study aims to explore the communication capabilities for video crucial applications of two commercial drones—the Parrot AR.Drone 2.0 and Anafi—in a greenhouse environment. Experiments were conducted on Received Signal Strength (RSS), Round-Trip Time (RTT) throughput 802.11n at 2.4 GHz network. From experiments, it was found that none UAVs have an isotropic radiation pattern. Indoor measure...

A new approach to system linearization and decoupling is presented for climate control of greenhouses and more specifically for the operation of heating/cooling and moisturizing. High-level programming, which provides an easy way to building models, is a feature of most research but also field control systems. The method is applicable to any air-conditioning system and is expected to gain wide ...

The National Research Council’s Committee on Agricultural Education in Secondary Schools recognized the value of supervised experience and recommended that all students participate in worthwhile supervised agricultural experience (SAE) programs (Committee on Agricultural Education in Secondary Schools, 1988). The committee indicated that these programs should include experience in land laborato...
