| Greenhouse structure is one of the most important factors in the greenhouse industry; increasing energy prices is a major challenge for greenhouse owners. Greenhouses should be so designed that they have high light transmission especially in winter and at the same time satisfy the requirements of the construction cost and the safety against the loads which may be imposed upon them. In this research, the goal is to optimize the shape and direction of the greenhouse to minimize the energy required for heating. The design parameters in this work are determined for two different types of greenhouses with the target functions, with the gray wolf optimization method. Optimization of energy consumption for different models of greenhouse and different materials... |

| An approach to developing variable-rate sprayer technologies is to install electronic control systems on conventional sprayers. This study introduces a direct injection type electronic solution concentration control system. This control system was installed on a field sprayer, and then a map-based variable-rate sprayer was developed. The control system consisted of a chemical tank, a chemical metering pump, the metering pump’s driver, the metering pump’s speed sensor, the implement’s travelling speed sensor, an Electronic Control Unit (ECU), a GPS receiver and a mixing unit. The metering pump discharge was measured at different carrier liquid (water) working pressures (3, 4 and 5 bar) and different chemical metering pump shaft speed (100, 200, 300 and... |
