Abstract Studies and production experience show that with an increase in the mass and power-weight factor of tractors, the return on investment in this technical progress field decreases. The paper justifies that at the current stage, the priority is to reduce the energy consumption of mechanized processes and comply with agro-technological requirements in the changing natural and production conditions. It reflects the areas of designing tractors and the effectiveness of their operation. The compaction effect on the soil is shown, taking into account the types of movers. The authors propose to complete the tractor fleet for various agro-industrial organizations.

The Relationship

With the increasing deployment of IoT devices and applications, a large number of devices that can sense and monitor the environment in IoT network are needed. This trend also brings great challenges, such as data explosion and energy insufficiency. This paper proposes a system that integrates mobile edge computing (MEC) technology and simultaneous wireless information and power transfer (SWIPT) technology to improve the service supply capability of WSN-assisted IoT applications. A novel optimization problem is formulated to minimize the total system energy consumption under the constraints of data transmission rate and transmitting power requirements by jointly considering power allocation, CPU frequency, offloading weight factor and energy harvest weight factor. Since the problem is non-convex, we propose a novel alternate group iteration optimization (AGIO) algorithm, which decomposes the original problem into three subproblems, and alternately optimizes each subproblem using the group interior point iterative algorithm. Numerical simulations validate that the energy consumption of our proposed design is much lower than the two benchmark algorithms. The relationship between system variables and energy consumption of the system is also discussed.

Light Levels

The continual rising cost of energy, existing outdated lighting technology, and inefficient lighting designs have given property owners the opportunity to improve their facilities by retrofitting their existing luminaires with an energy efficient lighting system. A lighting retrofit uses the existing electrical infrastructure to replace, relocate, or convert existing luminaires with the latest generation of cost-effective components. New lighting technology has emerged within the last 6 years that generates energy savings of 40% to 50% while maintaining existing light levels. These upgraded and field-tested solutions lower energy consumption, generate a healthy financial return on investment, and can improve both the quality and quantity of light in the task area. As with any other solution, a cost-effective lighting system must be designed and engineered carefully to accommodate the needs of each work space. Simply installing a new lamp into an existing luminaire will not necessarily guarantee substantial energy savings or an improved lighting environment. In any space that uses electric lighting, the lighting designer must evaluate potential solutions for energy consumption, maintenance concerns, delivered light levels, hostile environments, and the overall economic impact of installing and long-term operation of the new system. In this paper, the author will discuss energy efficient lighting design criteria and how a lighting designer properly engineers a retrofit project to deliver energy savings without sacrificing light levels. The discussion includes a summary of both traditional and emerging technologies, and the long-term impact on energy consumption, maintenance, return on investment, lighting quality, and delivered light levels.

Air conditioning plays a significant role to maintain a cool atmosphere in warm conditions, However, the power consumed by the machine is higher. The commercial prevailing cooling systems are required to operate ventilation and cooling systems in buildings and in turn consumes more power. These systems apart from consuming electricity it also adds to the CO2 emissions to our environment. These energy consumption and CO2 emissions can be decreased by the assistance of energy effective frameworks to the prevailing air conditioning system. The study was conducted on a package unit of 414.2 kW by measuring the relative humidity, dry bulb, and wet bulb temperature to investigate the effect of indirect evaporative cooling on the systems COP. Also, the modelling of the package unit was done using Creo software and the analysis was carried out using ANSYS considering the flow and thermal analysis for different components of the package units. From this analysis it can be observed that by implementing the adiabatic cooling in package unit it is possible to save energy consumption. From the results it can be concluded that energy efficiency was more and the return on investment is high. Also, coefficient of performance of this machine is high and consumes less electricity and the expected energy savings is 20%.

The Impact

Implementing Photovoltaic Systems (SFV) Interconnected to the electrical network, the energy consumption of the network is reduced, thus the SVF is a good alternative in rates where the charge is solely for energy consumption. In this work is presented the analysis of the Great Demand rate in Medium Hourly Voltage (GDMTH) that will allow designing SFV interconnected to the network helping to reduce the maximum demand for peak hours and increase the impact of the generation of energy through the PV system at rates where hourly consumption is considered. The consumption of energy by the user is analyzed, identifying that the highest demand for energy occurs in the intermediate hours and lower consumption in peak hours, however reviewing the electricity bill, the charge for consumption during peak hours increases significantly, SFV sizing is presented to reduce the estimated consumption during peak hours and the return on investment is determined. Subsequently, the implementation of a prototype to generate, store, and manage the injection of energy during peak hours is presented, analyzing the impact on the electricity bill, therefore the reduction of cost demand and energy in this hour time, is corroborated with a reduction up to 37% of monthly electricity bill.

Mr. Haynes in his contribution to the Symposium, and also in previously published papers, has very adequately described the general development, advantages and characteristics of the maraging steels. However, as much of the information which he has given relates to the work done in the laboratories of International Nickel, and because we have only been able to find relatively little information available relating to production experience, we at Dowty Rotol set out to investigate the problems of steel making, forging, and resultant mechanical properties to be obtained under more normal production conditions. As landing gear manufacturers, our prime interest lies in the production of relatively large forgings of somewhat complex shape, and we were therefore particularly anxious to investigate first of all that our normal steel suppliers could produce material to the correct composition, that the material would forge as easily as conventional material, and that the subsequent forgings possessed adequate trans-verse properties, particularly insofar as ductility is concerned. In this latter connection, we had heard of certain difficulties encountered in the USA relating to inadequate ductility in large forgings, which they had concluded was related to the carbon and sulphur content of the steel: i.e. that it was essential to eliminate brittle intermetallic compounds such as titanium carbo-nitrides and titanium sulphides from the steel.

The study provides an assessment of the state and prospects for the development of information management systems (IMS) of agricultural enterprises in the context of modern macroeconomic instability, uncertainty and risks. The features of agricultural production that affect the nature and efficiency of the IMS use are defined. A modern functional approach to IMS assessment in the context of electronic modeling of business processes in the agro-industrial complex is revealed. A convergent feature of the current stage of the IMS development, due to the nature of the current macroeconomic situation, is defined. The role of IMS in the development of risk-oriented management is clarified. The article describes the existing theoretical and methodological approaches to risk morphology, as well as the strengths and weaknesses of centralized and decentralized risk management systems. Special attention is paid to the “modernization” risks that are most closely related to the IMS development.

The article is devoted to the solution of a topical issue- improving the efficiency of road transportation process on the basis of improving the methods of vehicles selecting for the transportation of certain agricultural cargo under the given operating conditions. It has been proved that significant number of parameters influenced on the efficiency of road transportation in agricultural production. In addition to the generally accepted factors (maintenance costs and fuels and lubricants), transportation conditions, type of cargo, type of unloading and loading operations have a significant impact in agricultural production conditions. It is proved that variety of agricultural cargo within one farm encourages enterprises to form a universal automobile park. As a result of the analysis of purchases of vehicles by agricultural enterprises, it has been determined that there are no stable approaches of enterprises to forming the automobile park, which confirms the thesis of the influence as big number of factors on the choice of vehicles for transportation in agricultural production conditions. The approaches to the definition of the reserves for increasing the efficiency of the available automobile park and to the formation of the optimal structure for certain operational conditions have been considered. The objective need for proper grounding of the choice of vehicle for the conditions of agricultural production, due to the need to take into account a large number of parameters that characterize both the vehicle and the cargo and transportation conditions. In this context, the authors have proposed for practical use an algorithm for selecting a vehicle to perform specific transport work on the transportation of agricultural products, which takes into account the set of vehicles characteristics, cargo type and transport conditions. Attention has been drawn on the need for a systematic approach to the selection of transport vehicles estimation criteria in agricultural production. Taking into account the size of the bulk density, the availability of loading and unloading facilities, the peculiarities of transportation conditions, the amount of average expenses per unit of transport allows to comprehensively assess a single vehicle, optimize the choice of vehicle transportation of concrete agricultural cargo, minimize financial losses, thus, to increase the efficiency of the transportation process in agricultural production. Consideration of the optimal list of vehicle parameters provided by the presented algorithm will increase the efficiency of the transport process in agricultural production, both by reducing operating costs and by saving cargo and time. The clear structure of the proposed algorithm, with justification of each of its steps and, the purpose of each step, certainty and discreteness makes it easy to solve with available software.
