Under‐impedance load shedding: a new preventive action against voltage instability
Authors: Hashemi Sayyed Mohammad , Sanaye‐Pasand Majid , Abedini Moein
Published: October 2018

Load dynamics play an important role in the voltage stability. Grid‐side short‐circuit faults may induce severe voltage drops at motor load buses. Once the fault is cleared, depending upon its clearing time, the load bus voltage may either return to its permissible range or degrade gradually until it collapses. From the short‐term voltage stability viewpoint, the former is a stable phenomenon, while the latter is an unstable circumstance and the load should be shed in order to prevent voltage instability from being spread over the grid. To cope with this problem, this study presents a new under‐impedance load shedding (UILS) scheme. A quadratic distance relay is used as the load shedding element. The trajectory of load impedance is monitored by the proposed UILS relay. Following the grid‐side fault clearance, if the impedance trajectory enters the load shedding zone and remains inside it for a predefined time, voltage instability is detected and the load is curtailed by the UILS relay. The proposed approach is tested on various networks, including a real power system model. The obtained results approve the efficiency of the proposed UILS scheme.
Voltage–current–time inverse‐based protection coordination of photovoltaic power systems
Authors: Singh Manohar , Agrawal Anubha
Published: October 2018

Increasing share of distributed energy resources (DERs) in power networks results in dynamic network topology and short‐circuit fault levels. Low fault infeed in PV connected power network will rarely damage any power components, but detection of faults is of prime importance. The existing over‐current, voltage, and impedance‐based relays may fail to detect/clear the faults. However, it is observed that PV infeed networks are generally weak and experience a collapse in terminal voltage with increase in current during the system faults. In this article, variation in fault currents and voltages is utilised for formulating a new voltage‐current‐time inverse (VCTI) mathematical relay model. The proposed relay model enhances the operating time of the relays and maintains the protection coordination for weak power networks, especially powered with high PV generation. Using this relay model, a cluster‐based protection coordination scheme for PV‐dominant penetrated power network is presented. The performance of the proposed relay model and coordination schemes is compared with inverse definite minimum time (IDMT) relays and other relying models. Based on the proposed relay model, a hardware relay prototype model has been developed and it is found that hardware results are highly stable and are within 3% accuracy of simulated results.
Availability analysis of power substation automation architectures with PRP and HSR protocols
Authors: Rubinstein Marcelo G. , da Vinha Thiago M.
Published: October 2018

Industrial automation has been widely used in electric power substations. In this context, the IEC 61850 standard provides for the utilisation of redundancy in the data link layer to increase frame reception probability. This study aims to evaluate the availability of two power substation automation architectures based on the IEC 62439‐3 standard, which describes two redundancy protocols named parallel redundancy protocol (PRP) and high‐availability seamless redundancy (HSR). The authors evaluate both architectures using either PRP or HSR protocol against using no redundancy protocols. The reliability block diagram method has been used, and afterwards, the mean time to failure and availability have been calculated. Results show that the utilisation of redundancy protocols allied to the repair during the mission allows classifying the architectures in the higher availability class according to CEI IEC 870‐4.
Noise‐resilient voltage and frequency synchronisation of an autonomous microgrid
Authors: Shrivastava Sonam , Subudhi Bidyadhar , Das Susmita
Published: October 2018

We present a new noise‐resilient secondary control scheme for voltage and frequency synchronisation of an autonomous microgrid (MG). The communication network is an integral part of distributed secondary control structure. The communication links among the distributed generator units are assumed to be ideal in nature. However, the communication links are subjected to uncertain noises, which can significantly affect the synchronisation performance of MG control. We consider the information received over the communication link is corrupted with generalised Gaussian noise. Further, the complete non‐linear model of the MG system has been considered for designing a robust distributed control scheme augmented with an auxiliary corrective control input to counterbalance the impact of noises. The performance of the proposed control scheme is evaluated by pursuing simulation of a MG test system in MATLAB/SimPoweSystem environment under load perturbation, changes in communication topology, communication link delays, data dropout, and variations in noise parameter. The results of a comparative assessment of the proposed control scheme with two approaches first a neighbourhood tracking error‐based control scheme and second a noise‐resilient control scheme are presented to illustrate the effectiveness of the proposed robust noise‐resilient control scheme in voltage and frequency synchronisation and accurate active power‐sharing.
Wide band wide scan low cross‐polarised grooved tapered slot antenna array
Authors: Kedar Ashutosh
Published: October 2018

The present study proposes a new geometry of tapered slot antenna (TSA), called as a grooved TSA (GTSA). The antenna is designed to operate in L‐band for phased array applications. The topology of TSA's fins is modified by introducing electrically thin grooves, which split fins into separate sections, electromagnetically coupled to each other. The motive behind this modification is to reduce high cross‐polarisation (x‐pol) level in the radiation pattern of TSAs by altering the flow of surface currents intelligently. The design and optimisation are done using commercial FEM solver, HFSS. Furthermore, an embedded performance of GTSA in 7 × 7 elements array is presented. The mutual coupling between the array elements is minimised by the introduction of metallic baffles parallel to H‐plane. GTSA demonstrates a fractional bandwidth of 0.58 illustrating a reflection coefficient <−10 dB, half power beam width not less than 120° and 90° in E‐ and H‐planes, respectively. It demonstrates an x‐pol level <−20 dB at the extreme scan angles (up to 60°) from the broad side. The GTSA array demonstrates a wide scan performance up to 60° from the broad side. The present work is extremely useful in the realisation of active‐phased array radars.

Context. Exoplanets have now been proven to be very common. The number of its detections continues to grow following the development of better instruments and missions. One key step for the understanding of these worlds is their characterization, which mostly depend on their host stars.

Aims. We perform a significant update of the Stars With ExoplanETs CATalog (SWEET-Cat), a unique compilation of precise stellar parameters for planet-host stars provided for the exoplanet community.

Methods. We made use of high-resolution spectra for planet-host stars, either observed by our team or found in several public archives. The new spectroscopic parameters were derived for the spectra following the same homogeneous process (ARES+MOOG). The host star parameters were then merged together with the planet properties listed in exoplanet.eu to perform simple data analysis.

Results. We present new spectroscopic homogeneous parameters for 106 planet-host stars. Sixty-three planet hosts are also reviewed with new parameters. We also show that there is a good agreement between stellar parameters derived for the same star but using spectra obtained from different spectrographs. The planet-metallicity correlation is reviewed showing that the metallicity distribution of stars hosting low-mass planets (below 30 M⊕) is indistinguishable from that from the solar neighborhood sample in terms of metallicity distribution.

Published: October 2018

Regarding polynomial functions on a subset S of a non-commutative ring R, that is, functions induced by polynomials in R[x] (whose variable commutes with the coeﬀcients), we show connections between, on one hand, sets S such that the integer-valued polynomials on S form a ring, and, on the other hand, sets S such that the set of polynomials in R[x] that are zero on S is an ideal of R[x].
Relationships between quantized algebras and their semiclassical limits
Authors: Oh Sei-Qwon
Published: October 2018

A Poisson ℂ-algebra R appears in classical mechanical system and its quantized algebra appearing in quantum mechanical system is a ℂ[[ħ]]-algebra Q = R[[ħ]] with star product * such that for any a,b Є R ⊆ Q, a*b = ab + B1(a,b)ħ + B2(a,b)ħ2 + … subject to {a,b}= ħ-1(a * b ‒ b * a)|ħ=0, … (**) where Bi : R ⨯ R → R are bilinear products. The given Poisson algebra R is recovered from its quantized algebra Q by R = Q/ħQ with Poisson bracket (**), which is called its semiclassical limit. But it seems that the star product in Q is complicate and that Q is difficult to understand at an algebraic point of view since it is too big. For instance, if λ is a nonzero element of ℂ then ħ - λ is a unit in Q and thus a so-called deformation of R, Q/(ħ - λ)Q, is trivial. Hence it seems that we need an appropriate 픽-subalgebra A of Q such that A contains all generators of Q, ħ є A and A is understandable at an algebraic point of view, where 픽 is a subring of C[[ħ]].

Here we discuss how to find nontrivial deformations from quantized algebras and the natural map in [6] from a class of infinite deformations onto its semiclassical limit. The results are illustrated by examples.

Authors: Baryła Mateusz
Published: October 2018

We use deep learning for problems in computer vision, image recognition and classification. Deep learning methods for fruit recognition are built with methods where features (in our case fruits key features) are processed and sent through multiple layers where transformations and computations are done sequentially to form a prediction model. Deep learning algorithms draws inspiration from many fields especially applied maths fundamentals like linear algebra, probability, information theory and numerical optimization. To the best of our knowledge this is the first web application for fruit recognition. Thanks to that users will be able to recognize most of the Vietnamese fruits without knowledge of Vietnamese language. What is more they can get a short description for each fruit and a video how to eat it. In the paper we compare different models of convolutional neural networks in order to find the best possible model of CNN. This system will is fine-tuned, what means that it learns on examples provided by users of application. Having that we propose algorithm which detects non-fruits pictures uploaded by user.

Backpropagation algorithm with fractional derivatives
Authors: Gomolka Zbigniew
Published: October 2018

The paper presents a model of a neural network with a novel backpropagation rule, which uses a fractional order derivative mechanism. Using the Grunwald Letnikow definition of the discrete approximation of the fractional derivative, the author proposed the smooth modeling of the transition functions of a single neuron. On this basis, a new concept of a modified backpropagation algorithm was proposed that uses the fractional derivative mechanism both for modeling the dynamics of individual neurons and for minimizing the error function. The description of the signal flow through the neural network and the mechanism of smooth shape control of the activation functions of individual neurons are given. The model of minimization of the error function is presented, which takes into account the possibility of changes in the characteristics of individual neurons. For the proposed network model, example courses of the learning processes are presented, which prove the convergence of the learning process for different shapes of the transition function. The proposed algorithm allows the learning process to be conducted with a smooth modification of the shape of the transition function without the need for modifying the IT model of the designed neural network. The proposed network model is a new tool that can be used in signal classification tasks.

Computer-aided processing of the oculomotor signal
Authors: Lewandowski Tomasz , Lewandowska Anna
Published: October 2018

Specific features of oculomotor signal and availability of high-end measurement equipment, as well as using modern IT techniques and tools creates the possibility of automatic processing of this type of data and extensive use of developed algorithms. Analysis of such data is a tedious and complex process so computer processing of the oculomotor signal makes the process less time-consuming, more precise and effective. The article discusses data filtering and removing noise, detection of saccades and fixations and determination of characteristic oculomotor parameters and then analysis using neural networks (unidirectional, two-layer neural network with backpropagation learning method and Kohonen’s self-organising network) and application supporting the analysis process. The proposed test method allows registration of a view path followed by its automatic analysis to obtain objective parameters characterising the movement of the eyeball. The motor apparatus of the eyeball, due to its high sensitivity to changes in the body, can serve as a measure of general health.

Authors: Gajos-Balinska Anna , Wojcik Grzegorz M , Stpiczynski Przemyslaw
Published: October 2018

During processing the EEG signal, the methods of cleaning it from artifacts play an important role. One of the most commonly used methods is ICA (independent component analysis) [1-3]. However, algorithms of this type are computationally expensive. Known implementations of ICA type algorithms rarely include the possibility of parallel computing and do not use the capabilities provided by the architecture itself. This paper presents a parallel implementation of the fastICA algorithm using the available libraries and extensions of the Intel processors (such as BLAS, MKL, Cilk Plus) and compares the execution time for two selected architectures in the PLGrid structure (Zeus and Prometheus).
Clustering qualitative data based on the flow networks
Authors: Lewicki Arkadiusz , Pancerz Krzysztof
Published: October 2018

The paper presents research results referring to the use of flow networks and ant colony algorithm in the problem of generating decision rules for the cluster analysis process. The experiments showed that proposed approach may prove particularly important, when we are dealing with data sets represented by categorical variables associated with the same number of objects for each variance. There are many cases when we have no knowledge about the allocation group of individual data received and in addition defining any metric to measure the distance between observations, does not give any satisfactory results. Meanwhile, the selection of features and the choice of the performance metric is the basic condition for the use of most known classifiers. The article presents a new approach to solve this problem and obtain satisfactory results. It is based on mapping the set of analyzed data into the flow network, calculating the maximum flow and determining the validity of nodes in the network to use the Ant Colony Algorithm to structuring information and determine significant relationships between data.
The introduction of resource-saving technology in water treatment plants
Authors: Alekseev Stanislav
Published: October 2018

The purpose of a technological research is the development of a technology that would allow eliminating the discharge of untreated washing water from a water station in Omsk into the Irtysh, with their repeated use. The paper presents the results of a technological research, which made it possible to determine the optimal technology option for reuse of wash water filters. The studies were carried out by the trial coagulation method, introducing a different amount of contaminated wash water from 10 to 30% into the initial river water and the reagents used in the waterworks. When the combined purification of river and untreated washing water, the turbidity in the settling process decreases to 4.35 mg / l. The efficiency of purification increases with an increase in the amount of raw washing water also increases up to 30%. The technological solutions adopted on the basis of the conducted studies formed the basis for the design documentation for the facilities aimed at developing the re-use of wash water from the Omsk waterworks. The facilities have been built and are being successfully operated now. The proposed solutions made it possible to reduce the intake of water from the source by 10-16.5% and to eliminate the discharge of the contaminated wastewater from the station into the river of Irtysh up to a volume of 51 thousand m3/day.

Published: October 2018

The article deals with the modification of cement compositions by a complex of modifiers, including superplasticizers and finely dispersed mineral fillers (micro fillers), based on local raw materials and by-products of the industry, as well as being capable of improving the physical and mechanical characteristics of cement concretes and solutions. The expediency of joint application of finely dispersed fillers and superplasticizers for obtaining materials with high performance characteristics is shown. The studies described in the article are aimed at expanding the raw materials base of mineral additives in combination with superplasticizers and studying their behavior in the cement system. As finely dispersed mineral additives, the following were used in the work: ground limestone from the overburden from the Mazulsky deposit, waste from sawing the jadeite of the Kashkaraksky deposit, a pulverized fraction of waste from crushing the Berezovskoye gravel, and Novosibirsk microsilica. It is shown that the introduction of the waste from sawing jadeite into the composition of the cement, along with microsilica, leads to increasing strength at bending and compression at 28 days. In the process of manufacturing a concrete and mortar mixture with the addition of limestone flour, increased gas emission was visually observed. The interaction was observed between the finely dispersed limestone flour with additives of plasticizing effect with the observed emission of complex gases, such as ammonium hydroxide, ammonium nitrate, and others.
Optical chemical sensor for solving gas analysis tasks
Authors: Maslennikov Aleksandr , Zubkov Ilya , Kovalenko S.
Published: October 2018

A brief review of the principles of constructing optical gas-analyzing sensors is presented. It is noted that the influence of humidity of the surrounding gas environment during gas analytical procedures using solid-state gas analytical sensors is a serious technological problem. It is shown that sensors of particular interest are functioning on the principle of absorption of the primary light flux because of their reduced sensitivity to fluctuations in the humidity of the carrier gas. The design and the gas analytical properties of an optical chemical sensor are described. Ammonia was used as a test substance in the studies and as a sensitive sensor coating; a functional polymer having a specific highly selective reaction to ammonia was used. The static properties of the sensor were determined, the effect of the carrier gas humidity on its output signal, as well as the stability of the gas analytic properties of the sensor when interacting with ammonia. Analysis of the properties of the optical chemical sensor allows us to conclude that the proposed sensor is promising for solving various gas analytical problems.

Features of the use of intangible resources for the life cycle stages of real estate
Authors: Peshkov Artem
Published: October 2018

Use of intangible resources that can replace the declining volume of material resources for investment and construction activities is a large reserve of economic efficiency. Moreover, in modern conditions, there is a real opportunity to realize the synergetic effects of expanding the scope of use of intangible resources in the construction. As research has shown, in the context of targeted and resource mobility, the project format of interaction between economic entities makes it possible to optimize the resource turnover and the communication potential of development. At the same time, projects cover the sphere of construction production, as well as the sphere of consumption of construction products. Thus, modern trends in the development of demand form a fundamentally new cost structure. The peculiarity of the new structure is that the proportion of intangible development resources is steadily growing.

Authors: Darina Yulia , Daurtsev Ivan
Published: October 2018

The crisis phenomena on the hydrocarbon, gas and other raw materials market make it necessary to search for new points of growth of the national economy in order to ensure the stability of the financial system to external factors. An increase of the population of fast growing companies, the growth rate of which can be intensified through interaction between business and the state is one of the effective mechanisms for overcoming resource dependences. The article discusses the mechanism of interaction of the business community with scientific organizations using budgetary funds, which has positively established itself in foreign markets, in Russia. The authors also examined the regional aspect of state support for such cooperation. However, according to the conducted research, this mechanism does not bring positive results because of some administrative barriers, such as extremely high level of accountability, low-effective control system and transfer of foreign technologies.
Strategic resources of the developer organizations after the change of legislation on the shared construction
Authors: Svetnik Tamara
Published: October 2018

An important and very significant for the construction industry issue is under discussion in this paper - possible losses of the strategic development resources that will arise as a result of the unsystematic solution of the problem of shareholders. It is shown that in the near future, due to the key importance of the construction industry in the development of the country and the difficulties that have arisen in its activities, it will be necessary to search for the appropriate solutions. At present, the attention of theorists and practitioners is directed solely at the consideration of the consequences of legislative changes for citizens and developers organizations. With the use of the I. Ansoff’s methodology, the need for the strategic management in the construction industry has been confirmed, and instability of the external environment for the construction organizations of the Irkutsk region at the end of 2017 and the expected turbulence from the middle of 2018 after the introduction of the adopted legislative changes and new rules of the game on the housing construction market has been expertly assessed. The strategic resources of the industry are singled out, and it is considered how the introduced changes affect their reduction in the near future. It is concluded that the measures proposed by the legislators are not aimed at solving the strategic problems of the industry, but at the expense of excommunication of developers from money and other strategic resources exacerbate the situation. The proposals on the systemic adjustment of the adopted laws are considered in the paper.

Published: October 2018

The lack of information about the correct ways of restoring historical masonry materials from cultural heritage structures tends to create more damage to the said structures. According to Cesare Brandi’s theory of restoration, existing historical materials must be replaced with their equivalent. This paper presents the chemical composition of historical mortars acquired from church ruins of barangay Budiao, Daraga, Albay, Philippines. The historical mortar sample was characterized using petrographic analysis, sieve analysis, atomic absorption spectroscopy (AAS), thermogravimetric analysis (TGA), and infrared spectroscopy (IR). Petrographic analysis shows that the mortar sample is bounded by 90% organic material particularly coral and is held together by microcrystalline calcite (micrite) matrix that comprises of 10% of the total sample mortar composition. Sieve analysis shows a well-graded particle distribution. Atomic absorption spectroscopy (AAS) was also utilized to determine the %Ca for each sieve fraction using HCl for acid digestion. TGA thermograph shows the non-linear drop in weight between 740°C and 850°C, which corresponds to the degradation temperature of calcium carbonate or limestone. IR analysis shows essential characteristic peaks of CaCO3 at 712 cm-1, 874 cm-1, and 1437 cm-1.

RBF NN-Based Backstepping Adaptive Control for a Class of Nonlinear Systems
Authors: Zhao Haibo , Wang Chengguang
Published: October 2018

There are many control methods for nonlinear systems, but some of them can not control nonlinear mismatched systems very well. Backstepping control has obvious advantages in controlling nonlinear mismatched systems. Thus we proposed a new radial-basis-function (RBF) neural network-based backstepping adaptive controller combining RBF neural network (RBF NN) and backstepping control for a class of nonlinear mismatched systems. We adopted RBF NN to approximate the system uncertainty. And we analyzed the controller stability using Lyapunov stability theory. Finally we chose sine signal as simulation input signal, simulation results show that the proposed control strategy has better adaptive ability and robustness than PID control, validating the effectivess of the proposed control strategy.

This paper proposes an application of a recent nature inspired optimization technique namely Moth-Flame Optimization (MFO) algorithm in solving the Economic Dispatch (ED) problem. In this paper, the practical constraints will be included in determining the minimum cost of power generation such as ramp rate limits, prohibited operating zones and generators operating limits. To show the effectiveness of proposed algorithm, two case systems are used: 6-units and 15-units systems and then the performance of MFO is compared with other techniques from literature. The results show that MFO is able to obtain less total cost than those other algorithms.
Mechanisms performance and pressure dependence of hydrogen/air burner-stabilized flames

Published: October 2018

The kinetic mechanism of hydrogen combustion is the most investigated combustion system. This is due to extreme importance of the mechanism for combustion processes, i.e. it is present as a sub-mechanism in all mechanisms for hydrocarbon combustion systems. Therefore, detailed aspects of hydrogen flames are still under active investigations, e.g. under elevated pressure, under conditions of different heat losses intensities and local equivalence ratios etc. For this purpose, the burner stabilized flame configuration is an efficient tool to study different aspects of chemical kinetics by varying the stand-off distance, pressure, temperature of the burner and mixture compositions.

In the present work, a flat porous plug burner flame configuration is revisited. A hydrogen/air combustion system is considered with detailed molecular transport including thermo-diffusion and with 8 different chemical reaction mechanisms. Detailed numerical investigations are performed to single out the role of chemical kinetics on the loss of stability and on the dynamics of the flame oscillations. As a main outcome, it was found/demonstrated that the results of critical values, e.g. critical mass flow rate, weighted frequency of oscillations and blow-off velocity, with increasing the pressure scatter almost randomly. Thus, these parameters can be considered as independent and can be used to improve and to validate the mechanisms of chemical kinetics for the unsteady dynamics.

A supply chain member’s coordination is a challenging issue and a key factor of success in business markets. In vendor-managed inventory systems, the vendor makes replenishment decisions at the site of buyer by which the supply chain can be coordinated more efficiently. Two integrated vendor managed inventory systems under continuous review and periodic review replenishment policies are developed considering partial backordering and limited storage capacity at the buyer’s side. Furthermore, traditional retailer managed inventory systems under the same settings are developed to compare against the integrated systems. Efficient algorithms are presented to derive the optimal values of decision variables. Finally, numerical experiments and comprehensive sensitivity analysis are used to show the applicability and efficiency of the proposed VMI systems.

Areal study of the Don territory provides researchers with the evidences of ethnic culture. Uniqueness of the semantic development of Don dialect phraseology in a modern research paradigm is perceived as a reflection of a national language background of linguistic-cultural community. A special mention must be made with regards to a particular nature of linguistic culture and dialectic terminology of Don dialects. When covering the role of terminology phrases in a dialect and the appropriateness of classifying them as dialect phraseological units, their continual relationship with ethnic and linguistic factors are worth mentioning.
Communication of Emotions by Characters in a Flash Fiction (Based on Short Stories by Thomas Mann)
Authors: Akasheva Tatiana V. , Rakhimova Nuria M. , Emets Tatiana V.
Published: October 2018

The paper is devoted to the issue of nonverbal explication of emotions in literary texts of a flash fiction. Nonverbal means of communication are studied in several directions. There are works reflecting this problem from the perspective of semiotics, linguistics, sociolinguistics and psycholinguistics. A number of scientists is engaged in lexical description of paralinguisms. The study of linguostylistic problems of paralinguisms in literary works presents a special interest. The appeal to this problem is explained by the fact that adequate interpretation of a literary text is impossible without the corresponding reader’s understanding of nonverbal means of emotional expression since this requires nontrivial intellectual operations and a certain breadth of knowledge. The study is based on the analysis of three short stories by a famous German writer Thomas Mann: Der kleine Herr Friedemann (1898), Tobias Mindernickel (1898) and Tristan (1902). The rationale of the study is caused by the immaturity of this subject in German. The novelty is defined by the study of paralinguistic units in literary texts of T. Mann. The purpose of the paper is to describe nonverbal means and to define their functional yield in a literary text. To achieve this purpose, the paper deals with continuous sampling methods, contextual analysis and interpretation. The study showed that Thomas Mann uses paralinguisms to describe the main characters generally applying characterizing, evaluation, text-forming and forecast functions. Paralinguisms ensure text cohesion, integrity of its perception and are always aimed to implement the author’s plan and create the fictitious world of a literary work and consequently, contribute to the expression of an idea and a subject. The materials of the given paper may be used in theoretical courses of German lexicology, stylistics and in practical classes on literary text interpretation.
Linguoculture of Social Networks in the Internet Galaxy: Horizontal and Vertical Outlook

Published: October 2018

Relying on theoretical background (philosophical, cultural, communicative, and linguistic concepts) and the empirical study of communication within such social networks as YouTube, Instagram and Facebook, the authors substantiate the advent and development of new cultures existing in the Internet Galaxy, i.e. linguocultures of social networks, in modern digital and mass-communication community. These new phenomena represent autonomous, high-quality standard and valuable communicative systems appearing on digital network platforms, which are characterized by particular linguistic and communicative aspects: symbolic tools of public communication, standards of verbal behavior, communication formats, principles of self-organization and self-reproduction. The authors also emphasize the autonomy of new cultures thus highlighting the intervention from social institutes of power and business to ensure social control and management, which, therefore, results in both horizontal and vertical dimensions of linguocultures within social networks. Taking the above into account the authors forecast alternative options related to the future of new cultures.

Published: October 2018

The paper considers the formation of entrepreneurial climate in the conditions of social and economic development of the region. At present, one of the priority directions of social and economic policy of the region is the development of small businesses. In turn, the entrepreneurial or business climate acts as a paramount component of small business development. The study of the current state of entrepreneurial climate in the region makes it possible to define current problems of its development and ways to solve them. The social mechanism of entrepreneurial enterprise climate formation in the region is directly focused on the formation of certain motives, ideas, behavior patterns of all business subjects (business community and authorities). This is revealed through the following principles: state support, priority objectives, equal conditions, diversification, partnership, social responsibility, social protection, public representation, exchange of experience, competitive advantage. For successful formation of entrepreneurial climate in the sphere of small business as a factor of social and economic development in the region it is critical to use such methods as monitoring, ranking, public-private partnership, business partnership, social support, multilevel training, multi-purpose competition, social selection, social cooperation in order to ensure interaction of small enterprises based on the principles of mutual aid, transparency and autonomy.
