Abstract The paper studies the prospects of using telematics data to support effective solutions for tracking and monitoring the condition of the power supply system (PSS) components of unmanned vessels (UV) through the determination of positioning and, accordingly, operating time of PSS components. The paper attempts to describe one of the modules of the proposed integrated telematics system for UV monitoring, diagnostics and control. For practical implementation of telematics for unmanned merchant vessels, an algorithm has been developed to diagnose the technical condition of PSS components based on the operating time and condition of the units and components of the UV PSS. The results obtained by the algorithm show the technical condition of the observed technical equipment, time of its operation, and justify the need for repair or its complete replacement. The block diagram presents the algorithm that employs a minimal set of data to determine the use of technical equipment for further planning of its preventive maintenance. The paper provides the graphical interpretation of data on the time of PSS components operation and an example of displaying the interface of the remote operator of the UV. It is proposed to use telematics for tracking and monitoring the UV PSS operation in order to improve the quality of equipment maintenance, provide rational use of resources, extend its service life, and plan the repair time. In the future, it is proposed to create an integrated intelligent system based on telematics data, which allows the UV control and monitoring of the technical condition of its equipment.

Influence Of Properties

Sustainable development of construction materials is directly related to research on the processes of hydration of binders. Builders need better types of cement, with lower cost and energy consumption in production. The development of spin chemistry methods allows us to consider the processes of hydration and structure formation of binders from the spin state of the elements involved in chemical reactions. Magnetic interactions have a significant effect on the spin dynamics and the control of the spin multiplicity of radical pairs. The practical implementation of magnetic effects on a binder can be carried out in various ways. However, a long-term impact can be achieved only by introducing ferromagnetic substances into the binders. In the paper presented the results of a study of the influence of the characteristics of finely dispersed powdered ferromagnetic additives on the strength characteristics of cement. Ferromagnetic additives regulate the behavior of the reactants during rotation during the hydration of the binders due to magnetic interactions and control the reactivity of the chemical reaction. A comparative analysis revealed that it is most expedient to use as powdery ferromagnetic additives are the waste from mining and processing enterprises of the Krivorozhsky field. The work investigated the magnetic and dispersed characteristics of 12 different dust. The experiments showed that the origin of dust and the method of their capture are determined their magnetic characteristics. Preparation of samples with the dust and determination of the strength characteristics of cement were carried out by standard methods. The results obtained made it possible to reveal the laws of the effect of the dispersed and magnetic properties of various dust on the degree of activation of binders.

The necessity of formation of resource-saving ekologiurad-based utilization system of agricultural machinery in agriculture was confirmed by studies conducted in the center FNAC VIM in 2013-2018 years during this period, information was collected about the structure of the charged parts of agricultural machinery (agricultural machinery) going to maintenance of the enterprise with the purpose of recycling. Qualified specialists of repair enterprises were involved in determining the status of parts of the utilized equipment, normative documentation and necessary equipment were used. Terms of operation were determined from the date of purchase until the receipt of the machine to the repair company. The obtained data were subjected to statistical processing in order to determine the effect of the terms of service on the technical condition of these items and determining the number of parts of different groups (in percentage) included in the utilized agricultural machinery, as well as one of the main factors for deciding the feasibility of recycling equipment. The aim of work is justification of alternative ecological oriented intelligent system “Selkhozretsikling” formation for realization of a new strategy of resources use connected with their reuse. The averaged dependences of the change in the coefficient of technical readiness for tractors and combines on their service life are determined. Making an informed decision about the appropriateness of further use the machine (repair or disposal), which is close (or reached) to the limit state depends on the accuracy and timeliness of receiving information about the level of loss of its fitness after a certain service life or operating time. As analysis showed in most farms (52%) the preparation of the components of wastes derived of operation technics allows to use their potential on secondary market. Theoretical works and legislative documents make it possible to carry out the necessary practical measures for the formation of a system for utilization of agricultural equipment.

Price Of Risk

В статье рассматриваются актуальные вопросы оценки рисков в работе рыбопромыслового флота. Определен состав основных технических и технологических рисков, а также рискообразующих факторов и причин, оказывающих негативное влияние на работу рыбопромыслового флота. Так, в число рискообразующих фактов входят: природные (штормы, ураганы, цунами, низкие температуры), техническое состояние судов, уровень технического оснащения рыболовных судов рыбопоисковой аппаратурой и спутниковыми системами и др. Риски в деятельности рыбопромыслового флота в основном взаимосвязаны. В этой связи при количественной оценке агрегированной величины всех рисков в работе рыболовного флота необходимо учитывать уровень взаимозависимости рисков и их коэффициент корреляции. Предложена методика расчета агрегированной оценки совокупного риска в работе рыбопромыслового флота. Приводится демонстрационный числовой пример практической реализации методики. Отмечается необходимость создания компьютерной программы реализации методики, что позволит выполнять весь комплекс расчетов агрегированных оценок совокупных рисков и эффективности мероприятий по снижению уровня рисков, а также цены риска. The article discusses topical issues of risk assessment in the work of the fishing fleet. The composition of the main technical and technological risks, as well as risk-forming factors and causes, which have a negative impact on the operation of the fishing fleet, has been determined. So, the facts include: natural (storms, hurricanes, tsunamis, low temperatures), the technical condition of ships, the level of technical equipment of fishing vessels with fish-finding equipment and satellite systems. The risks in the activities of the fishing fleet are mainly interrelated. In this regard, when quantifying the aggregate value of all risks in the operation of the fishing fleet, it is necessary to take into account the level of interdependence of risks and their correlation coefficient. A method for calculating the aggregate assessment of the total risk in the operation of the fishing fleet is proposed. A demo numerical example of the practical implementation of the technique is given. The need to create a computer program for the implementation of the methodology is noted, which will allow performing the whole complex of calculations of aggregated assessments of total risks and the effectiveness of measures to reduce the level of risks, as well as the price of risk.

The aim of the study was to determine the capacity of a selected section of the Sanna river, designated below the lower site of the weir in Zaklików. The capacity calculations included the conditions of flood water discharge, i.e. the reliable flow and the control flow, determined in accordance with the Regulation of the Minister of the Environment on technical conditions that should be ensured for the hydrotechnical structures and their locations. The paper presents the consequences of changes in the regulations regarding the determination of building type, for which reliable flow and control discharges are determined. These modifications in the regulations have an impact on changes in the determination of the probability value for water discharges related to the analysed weir. The calculation of the capacity of the tested section also took into account its technical condition, specifying the variant of calculations for the lack of maintenance works, i.e. for the current state and for the state after maintenance works, consisting in mowing vegetation on slopes and shaping the surface of river bottom, removing pits and shallows. The results of the calculations of capacity of the measured cross-sections showed that the performance of maintenance works will convey the flow of a Q3% reliable flow in the Sanna river, while the Q1% control flow will not fit into the riverbed and will cause inundation of the adjacent areas.

Previous research has revealed that passive (involuntary inhalation) tobacco smoking during gestation can have adverse effects upon the developing fetus. These prior investigations did not concentrate on changes in fetal morphology. This study was undertaken to delineate fetal neural abnormalities at the ultrastructural level in mice pups exposed in utero to passive maternal smoking.Pregnant study animals, housed in a special chamber, were subjected to cigarette smoke daily from conception until delivery. Blood tests for determination of carbon monoxide levels were run at 15-18 days gestation. Sciatic nerve tissue from experimental and control animals were obtained following spontaneous delivery and fixed in 2.5% gluteraldehyde in 0.1M cacodylate buffer pH 7.3. The samples were post-fixed in osmium ferrocyanide (1:1 mixture of 1.5% aqueous OSO4 and 2.5% K4 Fe(CN)6). Following dehydration, the tissues were infiltrated with and embedded in Spurr. Sections were stained with uranyl acetate and lead citrate.

Stationary Heat Transfer

Based on the solution of the problem of non-stationary heat transfer during fluid motion in underground permeable layers, dependence was obtained to determine the operating time of the geothermal circulation system in the regime of constant and falling temperatures. It has been established that for a thickness of the layer H <4 m, the influence of heat influxes at = 0.99 and = 0.5 is practically the same, but for a thickness of the layer H> 5 m, the influence of heat inflows depends significantly on temperature. At a thickness of the permeable formation H> 20 m, the heat transfer at = 0.99 has virtually no effect on the thermal processes in the permeable formation, but at = 0.5 the heat influx, depending on the speed of movement, can be from 50 to 90%. Only at H> 50 m, the effect of heat influx significantly decreases and amounts, depending on the filtration rate, from 50 to 10%. The thermal effect of the rock mass with its thickness of more than 10 m, the distance between the discharge circuit and operation, as well as the speed of the coolant have almost no effect on the determination of the operating time of the GCS in constant temperature mode. During operation of the GCS at a dimensionless coolant temperature = 0.5, the velocity of the coolant is significant. With an increase in the speed of the coolant in two times, the error changes by 1.5 times.
