Determination of the requirement for transportation and technological machines by clusterization of oil and gas production departments

The article considers the analysis of production indicators of oil and gas production departments with the aim of clustering them for the subsequent determination of the need for automobiles and technological machines. The departments have different sizes, power, are in different conditions, are characterized by different performance indicators, but at the same time they are equipped with vehicles according to the same standards. This leads to problems in ensuring the uninterrupted transport and technological service of the main production. In a number of departments, situations arise when the planned number of transport and technological machines is not enough to perform technological operations for the repair or maintenance of wells. In this case, vehicles are sent from another sub-division, thereby limiting their own transport service capabilities. Fleet planning often takes place taking into account the historical conditions of the department, which is generally applicable for old departments with an established well stock, but practically does not work for newly formed departments with large volumes of newly commissioned wells and complicated production conditions. These subdivisions are equipped with vehicles in relation to existing workshops with similar indicators, which most often leads to an insufficient number of machines and downtime of the main production due to lack of machines. In this regard, it is necessary to search for and justify those production indicators of departments that determine their differentiation. The aim of the paper is to increase the efficiency of transport and technological service of oil and gas production facilities based on determining the patterns of influence of production indicators of production and gas shops on the need for transport and technological machines and developing, on this basis, differentiated standards for equipping units with vehicles. Using machine learning methods, the clustering of production units was carried out, and the factors that determine the distribution of departments into four groups were identified. The main factors include the stock of wells in the department and the degree of complexity of this stock. Groups are determined by the degree of change in these factors. The presented approach and the resulting distribution can be used as a basis for more efficient standardization of the needs of departments in automobiles and technological machines and also as part of decision support systems for vehicle fleet management

JUMPING FROG METHOD FOR OPTIMAL CLASSIFICATIONS

In the article the problem of finding optimal classifications on a finite set is investigated. It is shown that the problem of finding an optimal classification is generated by a tolerance relation on a finite set. It is also reduced to an optimization problem on a set of permutations. It is proposed a modification of the mixed jumping frogs to find suboptimal solutions of the problem of classification.In the article the problem of finding optimal classifications on a finite set is investigated.

Accelerator complex based on DC-60 cyclotron

DC-60 heavy ion accelerator, put into operation in 2006, according to its specifications - spectrum, charge and energy of accelerated ions, has the high scientific, technological and educational potential. The highest possible universality both by spectrum of accelerated ions and acceleration energy and regimes was built in DC-60 heavy ion accelerator designing. The new interdisciplinary research complex based on cyclotron DC-60 makes it possible to create a highly-developed scientific-technological and educational environment in the new capital of Kazakhstan..

Effect of ECAP on microstructure and mechanical properties of Cu-₁₄Fe microcomposite alloy

In current study the Cu-14%(wt.)Fe alloy was subjected to 1-10 ECAP passes via route A and, in addition, to 4 passes via routes Bc and C. Microstructure of the alloy after ECAP was characterized using SEM and EBSD analysis. It was shown that the refinement of Fe particles largely depended on the processing route: route A was the most efficient and route Bc was the less efficient. After 10 passes via route A the average thickness of Fe particles decreased to about 3 μm from about 10 μm in initial state. However, the microstructure development in Cu matrix was found to be not dependent much on ECAP route – the average grain/subgrain reached value of about 0.25 μm (according to EBSD analysis) after 4 passes. The mechanical properties of the alloy were also found to be not sensitive to ECAP route

Between platonic love and internet pornography

The article sets out to show how an holistic approach in matters of sexuality is always more helpful than one-sided approaches. On the issue of internet pornography, the authors suggest that the recent anti-masturbation online movement ‘no fapping’ is based on wrong conclusions from insufficient evidence. We suggest that a holistic approach is called for, with emphasis on the embodied human. Abstinence or what is understood by ‘Platonic love’ is not a solution, according to Plato himself. From a phenomenological perspective, we suggest owning up to our strange bodies and habitualising sexual activity

Use of iodine and selenium enriched fodder rations for production of fortified young lamb

The article is devoted to preventive measures to eliminate the problem of dysmicroelementosis in order to increase the productivity of young sheep. The article presents the results of studies of the influence of feeding rations on the growth and development of young sheep of the Edilbaev breed, on the level of their meat productivity and the qualitative characteristics of biologically fortified lamb. Feed additives based on Yoddar-Zn and DAFS-25 were added to the main ration of lambs at the age of four months, once a day, being added into a fodder mixture with concentrates. For the experiment the herd of lambs was divided to four groups of 25 heads each.The changes in live weight at the age of four, five, six and seven months were analyzed, and it was found that at the age of seven months, the absolute average weight gain in the experimental groups varied from 3.45 kg to 4.49 kg, in the control group it was 3.1 kg, while the largest live weight gain was recorded in group III which received both feed additives based on Yoddar-Zn and DAFS-25.There were no significant differences in the parameters of body measurements, with the exception of group III, where the chest circumference increased by 7.2%, and the height of a lamb at the withers increased in average by 8.1%. It was found that group III had the highest meat density coefficient, equal to 3.9, and the cross-sectional area of m. Longissimus dorsi was equal to 13.61 cm2. It was noted that the amount of free amino acids of the lamb group III is 18.8% higher than the meat of the control group. The lamb obtained from the animals of the experimental groups showed a higher protein content and less fat. The ratio of water to protein in all samples was slightly higher than 3.7, which corresponds to the Federa number for meat raw materials. Enriching the rations of the Edilbaevskoy sheep with feed additives Yoddar-Zn and DAFS-25 promotes the stimulation of growth and development of animals, increases the productivity and nutritional value of lamb
