Authors: Sreena S. , Ilankumaran M. 
Published: April 2019

Language is a particular system of communication used by human beings. It consists of development, acquisition, maintenance and use of complex systems of communication. Learning a language is not only a matter of motivation, ability and background but also it depends on the social and linguistic environment of the learners. Human beings are separated to other species in the name of communication skills. Listening skills made the people understand what another person speaks. Speaking skills are helpful to convey the wishes and idea of one person to the other in the correct way. Reading skill is essential to interpret what is given in the text. Writing is to deliver oneâ€™s thoughts. Learning strategies and processes are the most effective when they are in line with the learning style preferences. So, it becomes useful to know which learning strategy is effective to help the learners acquire the knowledge quickly and effectively. Developmental speaking is the effective strategy to enhance the communicative skills based on the process of human brain. Communication skills are necessary for a person to develop the personality. Second language is the non-native language used by the people in a locality for the communication purpose. Second language can be acquired at any age with the strategy of developmental speaking. Cognitive approach is related to the psychological factors of an individual. The paper attempts to discuss a psychological approach to enhance communication skills using developmental speaking as a strategy.Â Â

Evaluation of Synthesized Catalytic Complex Structure-Forming Ability during Paraffin Base Tar Upgrade
Authors: F. Kemalov Alim , A. Kemalov Ruslan , Serge-Bertrand Adiko 
Published: April 2019

The combination of the synthesized multicomponent bifunctional catalytic complex (MBC) components with heavy oil residues (HOR) of the paraffin-naphthenic (P-N) base leads to the chemical structuring of the hydrocarbon (HC) segments of the raw material molecules, and the specifics of HOR physicochemical structure, which will be the criteria for the selection of modifiers with a certain chemical nature [1,2,3,4]. It has been established that the introduction of catalytic activators in the tar composition promotes both the intensification of the oxidation process and the production of bituminous insulating material (BIM) with high physicomechanical properties [1,2,4].Raw materials for the production of special bituminous materials must be highly resinous with a P-HC content of up to 3% by weight. Based on the works by A.S. Kolbanovskaya [6], this is explained by the fact that the dispersed structure of bitumen is significantly dependent on the content of P-HC, since the dispersed phase in the oils is formed by naphthenic (N-) and PN-A-HC at certain temperatures with the side chains of the paraffinic P-HC series. If their content is more than 3% by weight the crystallization skeleton of P-HC is developed, which provides stiffness and reduces the plasticity interval for the system. Together with this, it is known that in the process of HOR oxidation the amount of low-molecular-weight oil A-HC decreases continuously, and the relative amount of PN-HC increases. Due to this, the affinity of the dispersion medium (DM) decreases to asphaltenes [7,8,9], which, moreover, becomes larger, which leads to THE deterioration of the cohesion and adhesion-strength properties of BIM.Â Â

Published: April 2019

In recent years improving the efficiency of wood use is gaining ever-increasing relevance both in Russia and abroad. In issues related to the thermal modification of the properties of wood the increased interest of scientific community can be observed. Heat treatment causes a change in the physical properties and chemical composition of wood raw materials, which subsequently contributes to improvement of the performance characteristics of composite materials and the production efficiency of chemical products from thermally modified shredded wood. The purpose of developing this technology is to improve the performance characteristics of products made of wood-polymer compositions, as well as improved final qualities of the material, namely, the absence of the odor characteristic of thermowood and the formation of cracks on the surface of the material. The effect of the preliminary heat treatment of ground wood in disc-type reactors on water absorption, swelling and tensile strength and compression is established. In the future, the material obtained by this technology can be used in landscape design.Â Â

Published: April 2019

Solution of partial differential equations (PDEs) of three dimensional steady state heat conduction and its error analysis are elaborated in the present paper by using a Trilinear Galerkin Finite Element method (TGFEM). An eight-node hexahedron element model is developed for the TGFEM based on a trilinear basis function where physical domain is meshed by structured grid.Â The stiffness matrix of the hexahedron element is formulated by using a direct integration scheme without the necessity to use the Jacobian matrix.Â To check the accuracy of the established scheme, comparisons of the results using error analysis between the present TGFEM and exact solution is conducted for various number of the elements.Â For this purpose, analytical solution is derived in detailed for a particular heat conduction problem.Â The comparison shows promising result where its convergence is approximately O(hÂ²) for matrix norms L1, L2 and LÂ¥.Â Â

Published: April 2019

Tool wear plays a significant role for proper planning and control of machining parameters to maintain the product quality. However, existing tool wear monitoring methods using sensor signals still have limitations. Since the cutting tool operates directly on the workpiece during machining process, the machined surface provides valuable information about the cutting tool condition. Therefore, the objective of present study is to evaluate the tool wear based on the workpiece profile signature by using wavelet analysis. The effect of wavelet families, scale of wavelet and statistical features of the continuous wavelet coefficient on the tool wear is studied. The surface profile of workpiece was captured using a DSLR camera. Invariant moment method was applied to extract the surface profile up to sub-pixel accuracy. The extracted surface profile was analyzed by using continuous wavelet transform (CWT) written in MATLAB. The results showed that average, RMS and peak to valley of CWT coefficients at all scale increased with tool wear. Peak to valley at higher scale is more sensitive to tool wear. Haar was found to be more effective and significant to correlate with tool wear with highest R2 which is 0.9301.Â Â Â
On Structural Optimization of The Propeller Blade
Authors: Aleshin Mikhail , Smirnov Aleksandr , Murzina Margarita , Boldyrev Yuri 
Published: April 2019

The results of the structural optimization of propeller blades are presented taking into account its composite structure and pitch change mechanism of the propeller and using FSI (Fluid-Structure Interaction) approaches. The optimality criterion of the problem is the propeller thrust with optimization parameters being the characteristics of the internal structure of the propeller blade made from a composite. Together with the optimization of the blade shape, the problem is considered which concerns the reduction of the deformations caused by loads occurring during the operation of the propeller, since significant deformations of the blades lead to decreased thrust.Thus, the following optimization problem can be formulated: to find the optimal configuration of the composite material and its micro-geometrical parameters along the height of the blade to minimize deformations and increase the thrust of the propeller. At the same time, the optimization parameters are limited by the weight of the propeller and the strength characteristics.The technique presented in the paper allows us to obtain the reliable values of thrust and reduce the estimated computational time. The influence of the structure of the composite material on the mechanical properties of the blades is shown; the values of deformation of the blades under the action of centrifugal and aerodynamic loads are given.
