Minimizing energy expenditure is one of the main purposes of the managers of pressurized irrigation systems. From the energy consumption standpoint, they can reduce energy consumption by supplying a constant flow into the system (a scheme different from urban water pressurized networks in which water demands depend on users). Managers can keep energy demands (opening and closing valves) while meeting pressure restrictions. We developed a computer application in MATLAB containing a genetic algorithm to find the best moment to open and to close valves to minimize an objective function which measures the differences between the objective and the real injected flows. We tested this program in the pressurized irrigation network of the San Vicente Campus, University of Alicante (Southeast Spain) and we calculated the water and energy balance (from the later and present irrigation network) and the carbon credits not emitted to the atmosphere.

At the stage of water treatment for irrigation systems, the efficiency capture coarse and fine mechanical impurities, as well as oil products and organic compounds affects the reliability of the equipment of the irrigation network and the safety of energy exchange processes in irrigated agricultural landscapes. The violation of work irrigation system can cause disruptions in irrigation schedules of agricultural crops, crop shortages, degradation phenomena on the soil and ecological tension. For the combined irrigation system, a water treatment unit has been developed, representing a hydrocyclone apparatus with a pipe filter in the case. For the capacity of 250 m3/h the main geometrical dimensions of hydrocyclone have been calculated. To organize the capture petroleum products and organic compounds, it has been proposed a modernization of a hydrocyclone unit, consisting in dividing the cylindrical part of the apparatus into two section. The first is section is for input irrigation water, the second one is for additional drainage of clarified irrigation water after sorption purification by the filter, placed on the disk and installed coaxially with the drain pipe and the pipe filter.

Software Component is a computer application that is useful for carrying out a desired job. This application is needed as a liaison between the brain (brainware) with hardware (hardware). Software also means a computer program that serves to perform special tasks, such as making documents, manipulating photos, making financial reports, or designing a house. Software can be divided into two, namely: System Operation. Software that functions to connect between users and computers, for example Windows 7, Windows 8, Linux, and Windows 10. Application. Software that can be applied to meet user needs. System network adapter drivers, network operations, and network protocols. As for examples of software in online communication, as follows. skype, hangout, web conference, whatsapp, Microsoft excel, video and audio, earlerning

Background: In order to study the interference of wired transmission mode on robot motion, a mobile robot attitude calculation and debugging system based on radio frequency (RF) technology is proposed. Methods: Microcontroller STM32 has been used as the control core for the attitude information of the robot by using MEMS gyroscope and accelerometer. The optimal attitude Angle of the robot is calculated through nRF24L01 which is the core of the wireless communication module, attitude acquisition module and wireless data communication upper computer application platform. Results: The results shows that the positioning accuracy is better than±5mm. Conclusion: The experimental results show that the proposed attitude solving and debugging system of mobile robot based on RF technology has better reliability and real-time performance. The propped model is convenient for debugging of mobile robot system and has certain engineering application value.

In order to revitalize Indian education system, the Government of India has recently approved National Education Policy-2020 (NEP-2020) and proposed sweeping changes including opening up of Indian higher education to foreign universities, dismantling of the UGC and the AICTE, introduction of a 4-year multidisciplinary undergraduate program with multiple exit options, and discontinuation of the M Phil program. It aims at making ‘India a global knowledge superpower’. In the light of National Education Policy-2020, agricultural education system needs to be redefined in India as it increases knowledge or information and farmer’s capacity to learn. As the level of agricultural education increases, farmers will become more and more self-reliant and will depend more on their self-studies dealing with farming. It is suggested that reorientation of agricultural higher education in context of globalization, food security, diversification, sustainability of ecosystems, and agribusiness is necessary. The curriculum of agricultural higher education needs to be made more broad based and manpower has to be trained scientifically in topics such as biotechnology, genetic engineering, agro-meteorology, environmental science, agro-ecology, computer application, information technology, conservation of natural and human resources, specialized job-oriented courses, and trade and export in agribusiness. Finally, adequate emphasis should be placed on practical skills and entrepreneurial capabilities among the students to achieve excellence. To properly address the challenges faced by today’s Indian agriculture, competent human resource in sufficiently large numbers would be required in the near future. There is a vast scope for young graduates to undertake agriculture as their profession which is directly or indirectly contributing to the economic and social development of the country.
