Published: July 2019

In 2017, a significant number of individuals profited from the staggering growth of the price of Bitcoin from $800 USD in January to almost $20,000 USD in December. Because the cryptocurrency market being relatively new when compared to traditional markets such as stocks, foreign exchange, and gold, there is a significant lack of studies in regard to predicting its price behavior. This research is interested in evaluating a number of regression-based algorithms in predicting the price of the Bitcoin (BTC) against United States Dollar (USD). Among the algorithms that will be investigated include the Linear Regression (LR), Neural Network Regression (NNR), Bayesian Linear Regression (BLR), and Boosted Decision Tree Regression (BDTR). By applying such regression-based analysis algorithms, the findings f should further help document the behavior of such a brand new, challenging yet extremely lucrative market.Â Â

The research was aimed at determining the optimal dosage of "STEMB" (Embryonic Stimulant) for preventing delivery and postnatal complications, for which purpose 4 groups of 20 cows in each were formed. During the experiment, the animals in the studied groups were in similar feeding and keeping conditions, dry matter in the diet amounted to 44.95%. The animals in the experimental groups received "STEMB" subcutaneously three times in the 30 days period before delivery with the interval of 7 days in the following dosages: the first experimental group received 0.05 ml per 1 kg of live weight; the second experimental group received 0.075 ml per 1 kg of live weight; the third experimental group received 0.10 ml per 1 kg of live weight; the cows in the reference group did not receive the preparation. It has been determined that the dosage of "STEMB" equal to 0.075 ml per 1 kg of live weight prevents postpartum complications, shortens the labor and the postpartum period. The obtained data may be used for developing the reference criteria of using "STEMB" for correcting the reproductive function and preventing complications during delivery and postnatal complications.Â Â Â

The modern stage of global financial market development is marked by intensive innovation. One of its peculiarities is quick formation and improvement of activities carried out by international regional development banks.The establishment of international regional development banks happened in the 1960s. During this period, development banks were founded in the countries and regions that got free from colonial dependency.At present, concerted efforts are observed in the sector of international regional development banks.During half a century of the activities, the mission, goals and operating principles of international regional development banks have changed conspicuously. Now their priorities are to finance long-term programs of regional infrastructure development, to invest in global projects and to lend socio-economic development programs.Along with earlier established international regional development banks, new institutions are also created. The primary reason for the establishment of these financial institutions is a regionâ€™s need to draw global investment.One of the newly established regional development banks is the Eurasian Development Bank that substantially differs from banks in operation. The Bankâ€™s primary specific features are the parity compliance with the interests of the regionâ€™s countries and the attainment of socio-economic tasks related to the regionâ€™s development.Â Â

During its formation and improvement, cattle acquired a number of biological and economic-useful qualities, which allowed identifying separate groups of animals with high productivity and productive longevity. One of the main criteria for cow selection for further breeding is the quantity and quality of dairy products [4]. Profitability of dairy farming largely depends on both milk yield and theÂ reproductive ability of cows. Troubled calving and subsequent diseases and complications affect the state of the animal organism; preservation and restoration of the health of a cow after troubled calving require considerable expenses. This research was aimed at examining milk production in cows with easy and troubled calving. To achieve this goal, in the studied number of cows with easy and troubled calving, the authors analyzed the following parameters: milk yield during the first lactation, fat and protein mass fraction, the amount of milk fat and milk protein; milk productivity was also studied, depending on the age at first insemination and theÂ duration of the service period. It has been found that milk yields in the cows with troubled calving were higher than in the cows with easy calving. The influence of the age at the first fruitful insemination on the further milk productivity has been determined: the highest yields were obtained from the cows with the age at the first fruitful insemination in theÂ interval between 15.1 and 17.0 months. The maximum milk yields during the first lactation â€“ 6,206 kg - were observed in the cows with relatively short service period (61 to 90 days).Â Â

Published: July 2019

The purpose of the construction of a coal open-cut should be an achievement in the shortest possible time of an access to the mineral deposit and creation of favorable mining conditions for achieving the specified performance. In the con-text of investment restrictions during the construction of the mine, the volume of preparatory work should be minimized (preparation of the surface of the quarry field, organization of the field drainage system, creation of a system of tracks, construction of installation sites, power lines, electrical substations, warehouses, and other infrastructure facilities).The main reason for the failure to comply with the deadlines for the commissioning of coal mines is the un-preparedness of the mining front, so the priority in determining the sequence of putting infrastructure facilities into operation is their influence on the development of the mining front.Justification of the sequence of input of mining sites in the development should be carried out based on the analysis of mining and geological conditions, as well as take into account the location of mining sites relative to the systems of transport and energy communications.The creation of the necessary infrastructure should be carried out in stages with the transfer of costs to the later periods of operation of the mine, when conditions for reinvestment from the company's profits will be created.Â Â

Published: July 2019

This article discusses the influence of conditions of secondary polypropylene recycling in the presence of vegetable fillers on thermal properties of polymer composites. Secondary polypropylene was recycled by the following methods: extrusion using two-screw extruder, agitation in mixing chamber of laboratory station (plastograph), die casting. Polymer composites on the basis of secondary polypropylene in the presence of vegetable fillers (wood dust, rice hulls, buckwheat hulls, and chaff) were produced by extrusion. Thermal properties of polymer composites were determined by thermogravimetric analysis and differential scanning calorimetry. It is established that recycling of secondary polypropylene by various methods does not change melting and crystallization points of polymer phase but is accompanied with decrease in melting enthalpy (by 9-11%) and crystallinity (by 5.6-6.5 %). The polypropylene samples obtained by recycling are characterized by lower thermal stability in air in comparison with initial polypropylene. Addition of vegetable filler to polymer composite on the basis of secondary polypropylene significantly decreases (by 1.13-1.48 times) melting enthalpy and crystallization of polymer phase. The compounds are characterized by relatively high thermal stability: their initial destruction points are close to parameters of initial polymer.Â Â

Published: July 2019

The article proposes the methodology for the automated classification of uplands using Geographic Information System (GIS) and Neural Expert System (NES). Quantitative indicators of topography are used as the basis of the proposed classification. A database consisting of topographic, soil, and land use maps was created using ArcGIS 10 geographic information system. A topologically correct digital elevation model (DEM) was created by the ANUDEM interpolation method. The DEM contains the following maps: hypsometric, steepness and slopes exposure, plan, profile, common curvature of the ground surface, and cumulative runoff maps. The boundaries of elementary surfaces (ES), which are homogeneous morphological formations, are established. Parameters characterizing the Stream Power Index (SPI) are taken into account. The essence of the proposed classification consists in attributing of ES to a certain group of lands based on aggregate of features. To do this, partial scales were created, containing indicators of topography, soil cover, land drainage conditions, as well as the degree of erosion development. The authors formed knowledge base for traning the NES using GIS database and partial scales of estimates. Teaching of neural network was carried out. The classification and topology of land was carried out by means of the NES. The uplands are distributed in flat and slightly convex areas. They are characterized by the following indicators: the curvature of the ground surface: plan curvature (0 â€“ 0.03), profile curvature (0 â€“ 0.15), common curvature (0 â€“ 0.22); slope angles (less than 1.5Ð¾); horizontal dissection in elevation (less than 0.5 km/km2), vertical dissection (less than 5 m); and SPI (from -13.80 to -6.47). Electronic map of uplands of LLC Â«SalairÂ» land-use area was created in the ArcGIS 10 environment.Â Â

Published: July 2019

The article presents the results of years of research conducted in order to establish the optimal parameters of agrophysical soil properties with different ways of its treatment in the agrotechnologies of row crop production. The studies were conducted on the following soil treatment systems: plowing the soil to a depth of 25-27 cm (at a stretch (control); chisel soil treatment to a depth of 38-40 cm (at a stretch); surface treatment of the soil to a depth of 10-12 cm (at a stretch); and combined soil treatment system. The study demonstrated the typical relationship between the structure and density of the compact chernozem, different for the seed and the underlying layers. The parameters of the agrophysical indices of the compact chernozem, which are actually attainable over the arable layer and favorable for tilled field crops, have been theoretically justified and experimentally confirmed.It has been found that for compact chernozem with high and persistent water stability (more than 68%) of the soil structure, unfavorable agrophysical indices are characteristic, sharply differentiated according to its layers: 1) the amount of blocky soil suite (structural aggregates of more than 10.0 mm) can reach 55% in the upper and 90% in the underlying layers of the arable layer; 2) the density of the arable layer of the soil is reduced to 0.94 g/cm3, while in the 15-25 cm and 30-40 cm layers it increases to 1.34 g/cm3.A correlation has been found between the density and share of the blocky fraction, negative in the 0-10 cm soil layer, and positive in the deeper layers. With an increase in the share of the blocky fraction, the upper layer of the soil acquires a loose structure (total porosity of above 60%), and the lower layers are compacted with a decrease in porosity to 50%.Â Â

Published: July 2019

This paper presents multi-instance (MI) image classification for cancer diagnosis using statistical mapping Support Vector Machine (SVM). The existing MI image classification is limited to focusing on standard multi-instance classification (MIC) assumption, but do not generalize to the whole range of MI data and do not fully utilize the power of conventional SVM. The standard MIC assumption labelled a bag of image as positive if there is at least one instance in it which is positive. Unfortunately, this assumption is not applicable if there is less information about abnormal instances provided in a bag. Therefore, the paper aims to propose conventional SVM that utilized the basic statistical mapping to form a bag vector of instances in order to classify MI images and give the benefit of the automated image diagnostic procedure. Numerical tests examine the benefit of instancesâ€™ features transformation to be a vector of bag representation using mean and covariance mapping to Linear-SVM, Square-SVM and Cube-SVM. The experiments used a secondary dataset. The numerical dataset extracted breast histopathology image of 58 patients, which contains 708 features and 2002 instances. The result obtained shows that the proposed SVM can achieve 100% sensitivity after utilizing the covariance mapping with Square-SVM. It means the classification task able to detect the malignant class. In conclusion, the conventional SVM has great potential to improve medical diagnostic procedure using MI image, particularly for cancer diagnostic after adapting statistical features transformation.Â Â Â

Published: July 2019

The article gives a brief analysis of methods and algorithms for the transformation of spatial rectangular coordinates to curvilinear coordinates - geodetic latitude, geodetic longitude, geodetic height. Two algorithms for solving the equation for determining longitude are considered. Three formulas used to calculate the height are analyzed, with an estimate of their errors due to the approximate latitude. The shortcomings of mathematical solutions to these problems are revealed. A study of different approaches and methods for solving the transcendental equation for determining the latitude, based on the theory of separation of the root of the equation, is performed. Using this technique, iterative processes were performed to calculate the reduced latitude , using trigonometric identities, by introducing an auxiliary angle and transforming it to an algebraic quartic equation, which Borkowski solves by the Ferrari's method. The determination of the root isolation interval allowed using the chord method (proportional parts) to determine the latitude. In all cases, estimates of the convergence of the iterative processes that facilitate the comparative analysis of the proposed solutions are obtained. By further decreasing the separation interval of the root, the accuracy of the non-iterative determination of the latitude is improved by the Newton method.Â Â
