The method of making road markings and performing automatic control of road traffic

Currently, the problem of energy independence is one of the most urgent. Consequently, there is a significant need for alternative sources of power. Along with this, throughout the history of human development, the issues of roads and their quality have been very topical and relevant. It is especially true for Ukraine. With the development of science and technology, these issues are expanded by functionality of roads, their safety both for drivers and for other road users and the ability to perform several functions simultaneously, for example, to provide transport traffic and generate electricity. Goal. The goal is development of the method of road marking and automatic control of the road traffic using multifunctional road panels. Methodology. The analytical methods of research on the development and application of methods and devices for transforming the energy of the sun into electricity were used. Methods of mathematical modulation were used when considering the principle of multi-functional road panels, combined in one system. Results. The functional features of multi-functional road panels of pavement are revealed and their scheme on the roadway is presented. The principle of operation of the road as a unified system of multifunctional road surface panels has been researched. The scheme of implementation of road marking and automatic control of road traffic is presented. Originality. It is suggested to use special plates – multifunctional road panels – instead of the top layer of the road cover. Such an upper layer of road clothing will allow the road, as an integral complex system, to perform several functions simultaneously: to be a part of the road for motor transport, to generate electricity and to draw a road marking independently, and if necessary – to change it. Practical value. The use of the proposed method of road markings and automatic control of road traffic will make possible quality performance and rapid change of road markings at any time of the year and day, depending on the current natural and traffic conditions. Also, the proposed road pavement will generate electricity as an alternative renewable source of energy

Визначення оптимальних параметрів навантаження для ефективної роботи кремнієвих сонячних батарей

Problem. Currently, the most commonly used method is the so-called direct method of converting solar radiation into electric current using a variety of solar batteries (SB). The most widely used in the application were silicon SB. Consequently, the question arises as to which optimal parameters should have an electrical load in order to ensure the efficient operation of SB. Goal. Determination of the optimal active load parameter for monocrystalline and polycrystalline SB, which meets the criterion for transmitting maximum power to load. Methodology. The analytical methods of research on the development and application of methods and devices for transforming the energy of the sun into electricity were used. Experimental methods of research and mathematical methods of processing experimental research were used. Results. The analysis of existing types of silicon SB is carried out, their classification is presented. The determination of the optimal active load parameter for monocrystalline and polycrystalline SB is carried out, which corresponds to the criterion of transfer of maximum power to load. The results of experimental studies are presented as volt-ampere characteristics and the dependence of the power of SB on the load current. An analysis of the results of experimental studies showed that for the most efficient operation of the SB, its active load should be maintained in the range from 3 ohms to 3,5 ohms. Originality. The method for determining the optimal electrical load parameters for silicon monocrystal and polycrystalline SB has been improved. The method of correlation of electric loading of SB to their own active resistance is presented. Practical value. The obtained results allow us to determine the optimal electrical load parameters for silicon monocrystalline and polycrystalline SB. If the types of SB in question are compiled into systems with a corresponding serial-parallel connection, then it is necessary to determine the internal resistance of such a system. Applying this principle, you can determine the optimal load parameters for any silicon solar system.Определены оптимальные параметры активной нагрузки для монокристаллических и поликристаллических солнечных батарей (СБ), соответствующие критерию передачи максимальной мощности в нагрузку.

Це досягається, зокрема, шляхом розробки та впровадження нових інноваційних спільних навчальних програм. До того ж, через зростання інноваційних енергоефективних та енергозберігаючих технологій важливо поліпшувати вищу освіту відповідно до змін у потребах економіки та соціальної сфери у секторі автомобільного транспорту, підвищувати конкурентоспроможність випускників у сфері зайнятості, впроваджувати продуктивну співпрацю між університетами. До того ж, енергетичні й екологічні проблеми в Україні змушують знижувати споживання енергії та заміняти традиційні джерела на «зелені» види енергії в усіх сферах життя і діяльності держави, зокрема і в транспортному секторі, що сприяє приєднанню навчального процесу до вирішення цих проблем. Проведено аналіз існуючих спільних освітніх програм для магістрів. Проведено аналіз та моніторинг ринку праці з визначенням його поточніх та майбутніх потреб, з урахуванням розвитку сучасного електричного транспорту.
