Determination and Evaluation of the energy consumption of grape production in Eyvan county (Ilam province) CIGR Journal
Kamari, Faraidon; Ghamary, Bahram; Azizpanah, Amir.
Grape is one of the most important fruits that has a long history of cultivation and production in our country. Effective use of energy in agriculture is one of the main reasons for the emergence of sustainable agriculture. It reduces environmental problems and pollution, prevents the destruction of natural resources and preserves fossil fuels. Energy analysis is also essential for the proper management of scarce resources to improve agricultural production and thereby identify efficient and economical production activities. In this research, determination and evaluation the energy consumption of grape production in Eyvan county (Ilam province). In the present study, the required data were collected from the presence method and a questionnaire was...

Precision spray modeling using image processing and artificial neural network CIGR Journal
Azizpanah, Amir; Rajabipour, Ali; Alimardani, Reza; Kheiralipour, Kamran; Mohammadi, Vahid.
This study employed artificial neural network method for predicting the sprayer drift under different conditions using image processing technique. A wind tunnel was used for providing air flow in different velocities. Water Sensitive Paper (WSP) was used to absorb spray droplets and an automatic algorithm processed the images of WSPs for measuring droplet properties including volume median diameter (Dv0.5) and Surface Coverage Percent (SCP). Four Levenberg-Marqurdt models were developed to correlate the sprayer drift (output parameter) to the input parameters (height, pressure, wind velocity and Dv0.5). The ANN models were capable of predicting the output variables in different conditions of spraying with a high performance. Both models predicted the...

Design, construction and evaluation of a sprayer drift measurement system CIGR Journal
Azizpanah, Amir; Rajabipour, Ali; Alimardani, Reza; Kheiralipour, Kamran; Ghamari, Bahram; Mohammadi, Vahid.
Spray drift study for reducing environmental hazards and protecting crops is of high importance as the pesticides used today are more active and many are non-selective. Drift potential can be restricted by assessing and optimizing equipment design, application parameters, the liquid spray properties, type of formulation and environmental conditions. The aim of this research was to design, construct and assess an intelligent system to determine the level of the spraying drift. The main parts of the system were liquid supply mechanism, pipes and nozzles, a controlled pneumatic system to pressurize the liquid, a nozzle moving system with a controlling panel and a tunnel for wind providing and control. To assess the performance of sprayer and drift of...
