HEAT AND AIR MODES OF AGRICULTURAL STRUCTURES
DescriptionIn this article, there are descriptions of ventilation systems of municipal and industrial buildings. We consider the scheme of natural ventilation and ventilation with mechanical drive. In agriculture production, processes accompanied by the releasing into the air of premises various harmful substances: gases and vapors, excess of heat and moisture. The source of the fumes and gases are various technological processes. People, animals and birds in the premises, release carbon dioxide and other gases. Sources of heat gain are the people, animals and birds, solar radiation, production equipment and so on. For optimization of parameters of the air environment, satisfying the hygienic requirements, need to install ventilation. The ventilation system – it is a set of devices for handling, transportation, supply and removal of air. The advantage of this article is the systematization of ventilation systems of production premises. We have identified the main flows of indoor air and placement of exhaust shafts. Greatest interest are the systems operating year-round or during the heat period and exhaust systems equipped with control devices in the form of a throttle valves or gate valves and a device for cleaning the air. We give sufficient attention to the thermal regime of premises, heat losses and heat gain through protecting designs. We indicated that a significant effect on the thermal state of premises might be provided by humidity level of fences, as well as potential of heat and moisture transfer

THE IMPLEMENTATION OF THE CONCEPT OF "ELECTRONIC GOVERNMENT" IN HIGHER EDUCATION
DescriptionIn the article, based on the generalization of long-term operation of archives of Kuban state University, we present current regulations and practice of work with archival documents, pressing questions of transition to paperless acquisition, storage and use of documentary resources of the organization. The author conducted a detailed analysis of the functioning of the archives of the University taking into account the specifics of the focus of the organization, defined the main tasks of the archive. The role of the archive is considered in the context of source of historical and cultural heritage of society. We highlighted problems of control and storage of archival documents, due to the steady growth of documentary information. Due to the rapid development of electronic document management today, the approach to the management of archival documents is formed based on electronic technologies. Based on the analysis and the identified problems, the article presented constructive proposals for the introduction of an electronic document archive organization if the interaction with the EDMS and other systems. To speed up the process of working with paper media, we might use the technology of digitization. It is obvious that now, without implementation of modern information technologies it is impossible to organize effective accounting, storage and use of archival documents

MEANS OF SHAPING AND FORMSERIALIZE IN MODERN FUR CLOTHES
DescriptionIn the article, we perform an analysis of the means of shaping and formserialize in fur clothes taken in the production of domestic and foreign fur companies. The spatial form of fur garments is solved, in the main, constructive. The type, direction and amount of articulation were determined by the design of the product and the properties of the fur: the height of the hairline, the size of fur semi-finished product. The proposed positioning of the shaping of articulation in fur clothes has to be performed in the environment of 3D CAD. It is established that in modern models of the silhouette of a fur product may be formed not only by design divisions but also by a combination of the product of different types of fur. We have performed studies on the use of funds of formation in models of industrial collections fur coat 2015-16 presented on the trading spots of Moscow. We have conducted a monitoring of consumer preferences on the types of fur among women and determined the causes of loss of fur, clothing of spatial forms under adverse conditions of wearing. We have also proposed innovative means of formserialize in a fur garment of solid and perforated fur

HARDENING AND SOFTENING OF CLAY SOIL
DescriptionHardening of clay soil manifests in the form of increase of the resistance of sample to shear deformation. The shear tests of normally compacted and overcompacted soils give values of peak strength at small strains and long-term strength at high. A shear test with constant strain rate of deformation (CRD) with continuous recording of resistance encounters uneven resistance change and the cyclical rate of change of resistance (RCR). The identification of cycles of the SIS allowed us to divide the deformation in each cycle for elastic and inelastic, corresponding to the ascending and descending branches of cycle. On an interval of the total resistance, the increases of the increment of inelastic strain are positive up to some critical value of the total deformation of the sample at which their sum reaches a maximum. This maximum is adopted as a measure of hardening. With further shearing of the sample, inelastic increments are negative, and their sum is monotonously decreases and reaches negative values for the total destruction of the sample. This value is taken as the softening. A symptom of total failure of the sample is the decline of absolute values of inelastic increments of resistance to zero. In general, the trend of the increments of inelastic and elastic increments of the resistance of the sample indicates the development of the destruction of the soil sample on the sliding surfaces and, in particular, yielding of the total surface. The sum of elastic increments of the resistance monotonically increases throughout the shear

RESEARCH THE FILLING PILE’S SETTLEMENT IN CLAY SOILS DURING REPEATED STATIC LOADING
DescriptionThe object of the study is bored piles and their joint work with clay soils. The analysis of the field of static tests of bored piles, arranged by continuous flight auger technology (CFA), was carried out by repeated loading. Curve of settlement and the rate of its development from the applied force was obtained. Linear relationship reducing the amount of settlement in the second cycle from residual displacements after unloading pile on the first cycle was found. There was a relationship increment of settlements in the second cycle from the involvement of the bottom end in the work

Description
Waterflooding helps in the recovery of great amount of oil that would have otherwise been abandoned in the reservoir that is depleted. A reservoir in the Niger Delta, Reservoir X has been used to illustrate this. Reservoir X had oil initially in place as 7.345 MMSTB and was produced for some time with the reservoir natural energy. The remaining oil in the reservoir as at the time that the natural energy of the reservoir was no more sufficient to produce oil was 2.96MMSTB. The reservoir has been left as depleted reservoir with the remaining oil in it. But from the analysis conducted in this work it is seen that if secondary oil recovery project by waterflooding is embarked on the reservoir, part of the remaining abandoned oil would be recovered. With the specifications given, about 1.22MMSTB of the 2.96MMSTB of oil in reservoir X would be produced as at the breakthrough time of 580 days. Moreover, considering the economic aspect of the project, reservoir X and is good to be invested in. From the NPV calculations performed, it is seen that the NPV of reservoir X at discount rate of 10% is $4.13 million

Description
Car license plates recognition problem is one of the typical tasks of computer vision. Video surveillance software usually provides license plates recognition function. Meanwhile, there are many approaches to solve this problem, where template-based methods are the most common. Such methods providing predictable and short enough execution time, and little percent of mistakes. However, such methods are far less effective in case there is a need to recognize car’s license plate, which may be located in unpredictable place, typed in undefined font and on non-standard background, or without strict formatting. For example, USA car license plates. One of the methods to increase effectiveness and quality of such license plates recognition is to use neural networks. It is assumed, that neural networks usage can significantly increase recognition quality. Nevertheless, neural networks usage entails difficulties of it’s training, and often becomes less efficient as template-based methods usage. This article discusses probability of usage of convolutional neural network, which was trained using MNIST (Mixed National Institute of Standards and Technology) database. This article is a review of usage of templates and neural networks for car’s license plate recognition in terms of quality, performance and complexity of the usage

SEED GERMINATION OF SPECIES RANUNCULACEAE OF YAKUT FLORA
DescriptionThe work was done based on the collection of the natural flora of the Yakut Botanical Garden. The object of research was the seeds of 22 species of the family Ranunculaceae. It is known that the seeds of many buttercup characterized morphophysiological tranquility associated with hypoplasia of the fetus (Nikolaeva, 1988; 1999), due to what delayed the germination of their seeds. Laboratory germination of seeds of the studied species varies from 0 to 100%. Among them, we have not found the kinds seeds which have explosive or fast germination (1 type of seed germination). The germination of the studied seeds states ranging from 6-7 days or more. The studied seeds were evenly distributed between 2 (12 species), and 3 types of seed germination (10 species). Type 2 is characterized by slow germination, type 3 - poor germination or lack of it

PROSPECTS OF CULTURE SPECIES OF BETULACEAE IN ROSTOV REGION
DescriptionWere summed up of perennial introductory tests of the representatives of the family Betulaceae S.F. Gray in the Botanical Garden SFedU. The 33 species of this family have been studied for a total. Evaluation of winter hardiness of the family members showed that the absolute resistance to the full range of factors winter have representatives genus Betula, also Alnus incana (L.) Moench and Corylus colurna L. Species of the genus Betula and Corylus may be attributed to the plants having a resistance to drought. The highly drought-resistant species – Carpinus betulus L., C. turczaninowii Hance, Alnus incana (L.) Moench and Ostrya carpinifolia Scop. Less than drought-resistant – Alnus glutinosa (L.) Gaertn. Most of the tested species should be attributed to hemixerophytes. The high degree of defeat by fungal diseases of the species genera Alnus, Betula and Carpinus makes them unsuitable for the regional culture. The causative agent of the disease is a fungus Chondrostereum purpureum (Pers.) Pouzar. Based on the totality ecological and biological properties only species of the genus Corylus remain promising for the culture. For introductory test it is advisable to attract drought-tolerant species of the family Betulaceae such as: Alnus barbata C.A. Mey., A. rubra Bong., A. rugosa (Du Roi) Spreng., Carpinus cordata Blume, C. caucasica Grossh., C. caroliniana Walter, C. orientalis Miller., C. tschonoskii Maxim., Betula insignis Franch., B. lanata (Regel) V.N. Vassil., B. luminifera H.J.P. Winkl., B. nikoensis Koidz., B. forrestii Hand.-Mazz., B. utilis D. Don., Ostrya virginiana K.Koch
