Analysis of the use of automatic control systems for the destruction of weeds in the conditions of organic cultivation of vegetable and row crops

Puprose. To analyze the state of development of MTU automatic control systems in the world and Ukraine and determine the rational direction for the development of new systems. Reducing the cost of manual labor for the destruction of weeds when growing environmentally friendly vegetable and row crops. Reduction of protective zones during the destruction of weeds in row-spacings and rows of vegetable and tilled crops. Methods. Monographic, analytical, abstract-logical, structural modeling, design and manufacture of alternative MTU automatic control systems for the implementation of effective methods of weed control in the organic farming system. Results. The analysis of technological solutions was carried out using specialized technical means equipped with automated control systems of the MTU. A technical and economic analysis of the use of technical means for the automated control of the MTU was carried out. The structural and functional scheme of the system for automatically bringing the working bodies of the row cultivator to the row of cultivated plants is substantiated. Conclusions. According to the results of the analysis, it was found that for automatic driving of the MTU in aggregation with agricultural technical means, it is most relevant to use GNSS tools, which are a satellite navigation system created for the purpose of positioning (determining the location in space – that is, coordinates) of objects. The automatic control system developed at the IMA AIP NAAS will allow to increase the productivity and quality of weeding operations by mechanical cultivators when working with minimal protective zones (2–3 cm) or weeding in a row of agricultural crops (corn, sunflower, tomato seedlings, garlic) with polyurethane finger-star discs.

Developing Novel Technologies and Services for Intelligent Low Voltage Electricity Grids: Cost–Benefit Analysis and Policy Implications

The paper presents a set of prototype smart grid technologies and services and validates the economic viability of the proposed solution using cost–benefit analysis (CBA). The study considered the EU-funded project called RESOLVD and implemented the technologies and services in a real-life pilot. The paper focuses on the analysis of technological solutions which enhance the operational efficiency and the hosting capacity of low-voltage electricity distribution grids. The solutions provided better integration of a hybrid battery storage system, with the grid interfacing power electronics, smart gateways for the interconnection of assets at the grid edge, and sensors enhancing infrastructure observability and control. The result from the CBA indicates the economic viability of the project, high scalability, and replicability. The economic benefits were realized with the breakeven value of eight secondary substations (SS) and 16 feeders. The scenario test on the DSO’s willingness to pay for the software as a service (SaaS) revealed that the payback period can further be reduced by almost half with a higher internal rate of return (IRR) and net present value (NPV). Both the CBA and scenario tests showed RESOLVD solution can become more economically viable when deployed in largescale. Moreover, the CBA results provide evidence to the energy policy by allowing DSOs to consider both CAPEX and OPEX for better investment decisions. Further, the paper proposes an alternative business approach that shifts from grid reinforcement to service provision. The paper also discusses the research implications on energy policy and business.

Optimization of the technological solutions for recharge and boron control system at the NPP for the project AES-2006

The article considers the possible ways to optimize the technological solutions of the recharge and boron control system of nuclear power plants under construction within the AES-2006 project. The possibilities for optimization of technological solutions of the system of recharge and boron regulation of the AES-2006 project, which will not affect the reliability and efficiency of its main functions: purge-recharge of the primary circuit and boron regulation, were studied. As a result of the analysis of technological solutions and analytical calculations carried out during the work, it was found that in the system of recharge and boron regulation of the NPP within the project AES-2006 it is possible to perform optimization basing on reduction the metal content of the heat exchange equipment by reducing the surface area of the heat exchangers of the coolant outlet, reducing the power of pumps, as well as reducing the diameter of a number of main pipelines. Implementation of the proposed optimization of technological solutions will allow a more rational arrangement of the system and reduce capital costs for the construction of nuclear power plants as a whole, while not adversely affect the safety of the system and its functions.

The possibility of low-budget GNSS equipment using for cadastral work for the Unified State Real Estate Cadastre purposes and transport link

The article considers geodetic methods for determining land plots location during cadastral work. The analysis of technological solutions in coordinates determining of the land plots’ characteristic points and their areas was carried out. The accuracy of geodetic methods in the cadastral work implementation was assessed. The priority technology was identified, including the use of low-budget GNSS equipment for this very task. The areas values were obtained and root-mean-squares of boundary marks position calculated by means of chosen technology are presented. The estimation and justification of the selected technology for cadastral work is given.

Automated Learning Support System for Adult Education Institutions and Enterprises

One of the actual problems in the world is how to successfully build efficient cooperation between educational institutions and industry representatives. The impact of technology on society is growing and there is a necessity for developing system supporting this cooperation. The system could be focused on knowledge sharing in both directions. It is possible to work more closely with an adult to provide effective learning solutions that meet their unique needs using an automated learning support system. The problem is the non-usage of knowledge management technologies and work-based learning potential to develop and use information systems for sustainable cooperation between education institutions and enterprises. The goal of the paper is to get a new perspective on an efficient cooperation support information system and understand the future of automated learning support systems involving the use of new technological opportunities. The main study question is how the automated learning support system could improve the effective knowledge flow between adult education institutions and enterprises. The research idea is to describe the principles of automated learning support focusing on an online system and knowledge management technologies for adults. The result of the research is the analysis of technological solutions, improved quality of knowledge flow and the information system as a cooperation platform.

Combined standardless electrochemical method for determination of lead(II), copper(II), and cadmium(II) in aqueous solutions

A combined standardless method (no calibration of the device against standard solutions or use of the method of additives is required) for determination of lead, copper, and cadmium in aqueous solutions is suggested. The method operates on principles of inversion voltammetry and potentiostatic coulometry. It is convenient for automated analysis of technological solutions and wastewater from electroplating and hydrometallurgical shops.
