This paper considers the results of virtual three-dimensional (3D) model use for the assessment of premaxilla position in 3-4-year-olds with complete bilateral cleft lip and palate (CBCLP) after primary cleft lip and palate repair. The use of 3D models allows measuring premaxilla size, protrusion and deviation. On the basis of measuring 3D full-arch jaw models before and after orthodontic treatment we distinguished 3 degrees of premaxilla deviation which may be useful for treatment planning and the prognosis of treatment outcomes. The children and their parents had good compliance with the use of intraoral scanning. Reviewing the literature we found the use of this method in newborns with clefts in order to manufacture a plate for pre-surgical orthopedics. However, we did not find any data of using this method to evaluate the result of surgical treatment in children with protruding premaxilla to determine the next stage of complex treatment. Compared to traditional cast and plastic model measuring, digital technology has many advantages: it is friendlier for children, more simple, needs less time and no materials for dental casts and plastic models, no storage space. There are no significant differences between manual and digital measuring of jaw models. Intraoral scanning and virtual 3D models may be successfully used for the assessment of premaxilla position in young children with CBCLP, which allows to asses surgical results and to choose the kind of orthodontic treatment.

The creation of technical objects which can replace a human when working in an unfriendly environment is an urgent problem. It is most rational to use anthropomorphic robots (AR) in these conditions. Due to the practical kinematics of the human body and the robot, it is able to use the appropriate infrastructure fully. The functioning of the AR in a non-deterministic environment determines the need to control and monitor the actions performed directly by an operator. Whereby it is necessary to solve two problems: the generation of control signals and evaluation of their working off by the AR. Due to the significant number of degrees of freedom of the AR, it is possible to do with the use of a set up copying-type device (ZUCT). The ZUCT is based on a lever system with a structural scheme identical to the human body. It allows to register through encoders movements in joints correctly and to provide generation of AR control signals. The AR is equipped with force sensors for solving the second problem. The loads registered with the use thereof are transmitted to the ZUCT equipped with a system of active drives. It allows to create loads on the body parts of the operator proportional to the loads in the kinematic pairs of the AR. The effectiveness of the developed control system was determined during the working off by the AR “FEDOR" control operations. Their full and unconditional execution with a satisfactory speed allows to claim that the copying control mode is the most rational today. Further improvement of this type of control system is possible due to reducing the weight of the set up device. The submissions reflected the major aspects taken when designing the control AM using ZUCT. For the first time, on the basis of fully implemented technical solutions, the overall, mass parameters of exoskeletons, specifications of the main used units are defined and presented. The feasibility of force-moment feedback allowing the operator to control the interaction of AR links with external objects is confirmed. The complete set of sensors and actuators used in the creation of ZUCT confirms, on the basis of the experimental studies, their sufficiency and the possibility of their use in the creation of new variants of control systems.

The presented work is devoted to the analysis of the phenomenon of "educational autonomy", its description and the need for its implementation in the system of ontent and language integrated learning by means of the mobile learning tools. The article also provides the results of a pedagogical experiment aimed at the efficiency improvement of the educational process at a non-linguistic university. The main purpose of the study is to develop an autonomous learning model based on such very popular mobile applications as Google products and to demonstrate the intermediate results of experiment training, prior to implementation of the model at two Saint-Petersburg universities: Polytechnic and Civil Aviation. For getting this goal the authors suggest defining a category of students' "autonomy" not only within the traditional autonomy focused approach, but also in the framework of CLIL. Hereafter the work is dedicated to the didactic opportunities of the M-learning and "BYOD" policy for higher education. The paper also describes didactic potentials of such Google products, as Google Docs, Google Drive are Google Forms are analyzed. The use of Google products at each stage of experiment training together with the freedom of choice of educational tasks and real-time discussions proved their necessity and positive influence on reading and vocabulary skills acquisition.

In-plant utility transport vehicles are one of the essential elements of a modern manufacturing enterprise. Their functional versatility required at the production facilities poses a challenge for design engineers to establish a comprehensive criterion basis used for search of optimum design parameters. One of the efficient tools to do so is applied numerical analysis allowing to reduce time of the search procedures and lay the groundwork for a rationale basis for the design solutions adopted. An engineering practice of design of a flat body for utility transport vehicles is described herein, with the reference to extensive use of numerical strength analysis for verification and elaboration of its design characteristics.

Transport Control Protocol (TCP) provides user with reliable data communication in cloud networks. Several control mechanisms of TCP have been introduced in order engage reliable smart cities communication Nonetheless, the conventional additive increase and aggressive multiplied decrease strategies that TCP protocol presently uses in congestion window adjustment could not fit well with the high-speed network bandwidth. Hence, high-speed transport protocols appropriate for next-generation Internet is now a subject of interest among scholars. Accordingly, the performance of three techniques of TCP protocols namely SACK TCP, TAHOE TCP and RENO TCP impacted by the node speed and packet size examined and reviewed in this study. The TCP protocols were assessed using average throughput (TP) and Average End-to-End (E2E) delay performance metrics. Meanwhile, the routing protocols were tested using the NS2 simulator. The proposed method is hence practicable in theory. As verification to the method, NS-2 simulations are presented

This article describes the development of the author's methodology for assessing economic potential. It is based on rapid assessment, which is carried out on three main components of economic potential: production capacity, financial potential and intellectual potential. The evaluation of indicators in this methodology will be carried out by the method of expert assessments, using the example of the industrial enterprise of PJSC "Nizhnekamskshina". The carried out approbation of the developed methodology allowed to make a number of analytical conclusions concerning the economic potential of PJSC "Nizhnekamskshina": during 2014-2015. Economic potential of the enterprise was characterized by a low level of financial and intellectual potential, in 2016 this indicator was upgraded to an average level due to an increase in the return on intangible assets. In 2017 average level of economic potential was maintained as well. The main problem side of the enterprise identified in the analysis is a low level of financial capacity which characterizes the critical insolvency of the enterprise and strong dependence on borrowed sources of financing. Accordingly, capital restructuring is one of the priority strategic tasks of PJSC "Nizhnekamskashina" and the main reserve of growth of financial and economic potential.

In this study, we propose and compare neural network models that use unsupervised layers for the prediction of financial time series. We compare the novel FL-RBM and FL-SMIA-RMB models that integrate a Restricted Boltzmann Machine (RBM) and the self-organizing layer of the Selforganized Multi-Layer Network using the Immune Algorithm (SMIA) with the FL-SMIA network and a standard MLP. We aim to investigate the performance of unsupervised learning in comparison to purely supervised and other mixed models. The FL-RBM model combines the products of raw input features (the Functional Link, FL), with the Restricted Boltzmann Machine RBM as a self-organizing first hidden layer, while the FL-SMIA model uses the Immune Algorithm on the first layer. The FLSMIA- RBM model, combines both self-organizing layers with a back-propagation network. The results show that the FL-SMIA model outperforms the FL-RBM, the FL-SMIA-RBM and the MLP as measured by Annualized Return (AR) in one-day-ahead prediction on exchange rates time series. In terms of volatility, the FL-SMIA and MLP perform similarly.

The process of cement manufacturing produces a huge amount of carbon dioxide (CO2). The utilization of alternative waste materials from various industrial processes as a partial substitution to cement is encouraged due to environmental and specific technical requirements. This strategy will have the potential to reduce cost of cement, conserve energy, and reduce waste volumes. Therefore, the aim of this research is to investigate effect of the replacement of cement with modified fly ash (MFA) and ground granulated blast furnace slag (GGBS) to reach 80% total replacement on mechanical and durability performance of cement mortar. Normal consistency, the initial and final setting times, compressive strength and electrical resistivity of all the ternary mixtures were determined and compared with the control binder. Compressive strength and electrical resistivity were tested at various curing ages of 3, 7, 14, and 28 days. Test results revealed that the normal consistency of the ternary mixtures increased with increasing the GGBS and MFA content, while the initial and final setting time decreased compared to that of control mixture. The results also showed that the compressive strength of all the ternary blends mortars were lower at early and later ages in comparison with control mortar. The reductions in the compressive strengths of the ternary mixtures T40, T60 and T80 compared to the control mixture were approximately 16%, 29% and 37%, respectively at 28 days. The surface electrical resistivity of ternary blends mixtures was higher than the control mixture at all curing ages. The use of GGBS and MFA in the production of cement mortar and concrete can significantly help in reducing the CO2 emissions of the cement industry and reduce the overall cost of cement.
