Authors: Borshch Olena , Borshch Volodymyr , Guzyk Dmytro 
Published: July 2018

In barrier building constructions the heat transfer occurs both at the expense of thermal conductivity and as a result of liquid and air vapors resistance. The mechanism of such resistance differs from classical processes of diffusion and the laws of hydrodynamics for integral medium.The temperature mode of the surface and deep layers of barrier building constructions in non-symmetric boundary conditions was analyzed. A mathematical model was developed that characterizes the change in the thermal state of barrier constructions during thermal diffusion. The method for calculating the non-stationary thermal modes of flat walls was presented.

Comparison Between PSO and Genetic Algorithms and for Optimizing of Permanent Magnet Synchronous Generator (PMSG) Machine Design
Authors: N A Prashanth. , Sujatha P 
Published: July 2018

This paper proposes application of Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) in the design of direct-driven permanent magnet synchronous generator machine (PMSGs) for wind turbine applications. The power rating of these machines is in the mega watt (MW) level. The constraints and requirements of the generator are outlined. The proposed design scheme optimizes various PMSG parameters like Pole pair number, Linear current density, Air gap thickness, Rotor outer diameter, Relative width of the permanent magnet etc to achieve certain objectives like maximizing efficiency, increasing Torque, improving power factor etc. The results obtained by GA algorithm and those by PSO algorithm are compared. The performance of Particle Swarm Optimization is found to be better than the Genetic Algorithm, as the PSO carries out global search and local searches simultaneously, whereas the Genetic Algorithm concentrates mainly on the global search. Results show that the proposed PSO optimization algorithm is easy to develop and apply and produced competitive designs compared to the GA algorithm.

Design of a Square-Shaped Broadband Antenna with Ground Slots for Bandwidth Improvement
Authors: M. Jyothsna K , Suganthi S 
Published: July 2018

This paper portrays the design of a compact square-shaped microstrip broadband antenna using ground slots. Polygon shaped slots are placed on the ground under the feed line for bandwidth improvement. Similarly, rectangular slots are placed on the square patch for gain enhancement. Effect of these slots on the performance of the antenna in terms of impedance bandwidth, gain and directivity are studied. Results of simulation tests show that a ground slot with proper dimensions placed under the feed line can improve the impedance matching and hence increase the bandwidth without affecting much the performance of the antenna. This compact antenna of size 9.098 x 9.098 mm can be very useful for applications where size is a major constraint. Simple microstrip feed is used to feed the patch. The percentage bandwidth of this antenna is 75.57 %.

Published: July 2018

This paper presents the development and characterization of aluminium alloy 6063 based metal matrix composite with varying combinations of fly ash and Borosilicate reinforcements. In the present work, the aluminium alloy 6063 (AA) is taken at a constant 84 vol% while the reinforcements Fly Ash (FA) and Borosilicate (B) are varied in the proportions of 2%, 4% 8%, 125 and 14%. Six samples were fabricated by stir casting and the mechanical properties were analyzed using tensile test, hardness test and wear test while the microstructure is analyzed by obtaining SEM and EDX images of the specimen. It is seen that both the reinforcements used in this study, increased the tensile and wear resistance of the alloy. The desirable mechanical and micro structural properties were found to be in the specimen with 84% AA, 14% FA and 2% B. The tensile strength of the aluminum alloy at this desirable combination is found to increase by 11.97%, ductility by 36.75% and the wear resistance by 62%. This metal matrix composite of AA6063 with fly ash and Borosilicate reinforcements can be used in automobile, aerospace and structural applications where wear resistance and tensile properties are mainly required.

Efficient Multilevel Privacy Preserving Authentication Scheme for Emergency Message Communication in VANE
Authors: Santhana Devi G , Germanus Alex M 
Published: July 2018

Vehicular ad hoc networks (VANETs) provide spontaneous traffic related and emergency rescue messages to its users of the route thereby enable them with the trouble-free driving. VANETs send emergency messages in times of exigencies that save people’s lives from disasters. Doing such times it has been a great challenge to ascertain the authentication and privacy of the messages that are broadcasted. Generally when the messages are broadcasted without accommodating privacy the confidential information’s like the vehicle’s id and location are exposed which adversely affect the users. In this paper to ensure privacy to the users we have recommended TA to provide a verification signature to all the vehicles which is mandatory for a vehicle for all its communication purpose. Normally in the existing schemes, the messages are provided with single level or bi level privacy features but, in the proposed scheme the emergency messages are provided with the multilevel privacy features. In the proposed scheme the TA provides a long term Verification signature which is mandatory to all the vehicles that are registered under VANET and this signature is also necessary in receiving the secondary token and common token from RSU at each interval of time. The authentication of the message is verified with the help of common token and encrypted common token as a RSU Verification signature. Since the emergency messages require secure, timely and factual communication our proposed protocol EMPPA scheme recommend the distribution of multiple verification signatures and tokens at various interval of time, so that the privacy, security and the authentication of messages are ensured to the VANET users.

Published: July 2018

The present study was carried out to analyze the performance of an anti-corrosion coating obtained from Carica Papaya extract and PMMA polymer applied on mild steel. This combination was characterized by using FTIR, XRD, Zeta potential measurements and thermogravimetric methods and the presence of major constituents in papaya extract was identified with the functional groups and hetero atoms which able to forms a passive film on the metal surface and protects mild steel from corrosion. These results were verified by visual observation and gravimetric method and then confirmed by electrochemical studies such as Tafel and AC impedance studies. Cyclic voltammetry result study showed that papaya extract confers electroactive property to the polymer. Zeta potential and contact angle measurements of this extract and coating material reinforce protection against corrosion due to high potential& more interfacial tension of the metal surface and hydrophobic nature of film, which repulse the water drops on metal surface, thus giving more adherent, non-porous film.

Authors: Supar Khairi , Hilton Ahmad Hilton 
Published: July 2018

Implementation of multi-bolts arrangements in structures connections are commonplace in steel design to allow for joint efficiency and stronger connections. Woven fabric kenaf fibers are potentially used as reinforcement in composite materials due to excellent specific strength, renewability and less hazardous during handling as compared to commercial fibers. A two-dimensional Extended Finite Element Method (XFEM) framework of single-row multi-bolted joints has been developed to study the stress distribution and predict the joint bearing stress at failure. Stress distribution among adjacent bolts were compared along the hole boundary and net-tension plane, suggesting net-tension failure occurred at end-bolt. The predicted bearing strength from finite element modelling are validated against experimental framework. The testing series under investigated consists of four datasets from single-row 2 bolts and 3 bolts single-lap joints. Current study showed that the XFEM models demonstrated good agreements with the experimental results.

Comparison of four different clutter profiles (border, seaside, free space and forest) using Forward Scatter Radar (FSR), which operates in Ultra-High and Very High Frequency (UHF and VHF) bands, is analyzed in this paper. Clutter levels ranging from low, medium, strong and very strong on each profile were studied. Based on the standard deviation of each clutter profile, border suits the best profile as the strongest clutter profile amidst seaside and free space, while the forest is determined as the lowest clutter profile. Subsequently, the characteristics of the clutter are investigated and compared based on the five distribution models (Log-Normal, Log-Logistic, Gamma, Weibull and Nakagami). The parameters of the five distributions are evaluated using Root Mean Square Error (RMSE) in order to prove that the distribution model fits best to the clutter data. It can be concluded that Gamma distribution is the best distribution model for all cases of frequency bands and profiles.

Leukocyte adhesion deficiency-I caused by a novel mutation in ITGB2 presenting with pyoderma gangrenosum
Authors: Haynes Alison , O’Keefe Andrew , Dancey Paul , Ohson Kamal , Turner Lesley , Chard Marisa 
Published: July 2018

Background: Leukocyte adhesion deficiency (LAD) syndromes are primary immunodeficiency disorders caused by defects in adhesion molecules on leukocytes resulting in impaired migration into tissues. Common cutaneous manifestations of LAD include bacterial infections, omphalitis with delayed separation of the umbilical cord, impaired pus formation and poor wound healing. LAD is associated with significant morbidity and mortality, making early diagnosis and management integral in the care of these patients. Methods: Molecular testing and flow cytometry for expression of CD18 were performed on 2 siblings presenting with cutaneous lesions including pyoderma gangrenosum (PG). Results: We describe 2 siblings with a novel homozygous mutation in ITGB2 (c.2070del, p.Asp690Glufs*25) resulting in an atypical presentation of LAD-I with PG. Conclusion: LAD should be considered in patients presenting with unexplained PG, even in the absence of significant infections or umbilical cord complications. Statement of novelty: To the best of our knowledge, we describe a novel homozygous mutation in ITGB2 (c.2070del, p.Asp690Glufs*25) resulting in LAD-I. Patients with LAD-I may present with unexplained PG and may lack classic symptoms including umbilical cord complications.
Circulating low density lipoprotein (LDL)

Published: July 2018

Abstract
Low-density lipoprotein (LDL) particles are known as atherogenic agents in coronary artery diseases. They modify to other electronegative forms and may be the subject for improvement of inflammatory events in vessel subendothelial spaces. The circulating LDL value is associated with the plasma PCSK-9 level. They internalize into macrophages using the lysosomal receptor-mediated pathways. LDL uptake is related to the membrane scavenger receptors, modifications of lipid and protein components of LDL particles, vesicular maturation and lipid stores of cells. Furthermore, LDL vesicular trafficking is involved with the function of some proteins such as Rab and Lamp families. These proteins also help in the transportation of free cholesterol from lysosome into the cytosol. The aggregation of lipids in the cytosol is a starting point for the formation of foam cells so that they may participate in the primary core of atherosclerosis plaques. The effects of macrophage subclasses are different in the formation and remodeling of plaques. This review is focused on the cellular and molecular events involved in cholesterol homeostasis.
“Stop doing this at once!”: The preferred use of modality for advice-giving by English language learners
Authors: Zalaltdinova Liya 
Published: July 2018

Abstract
This study seeks to explore (1) how English Language Learners (ELLs) of Chinese, German and Brazilian backgrounds develop their pragmatic knowledge of modality use for advice/suggestion-giving in English, and (2) if they demonstrate some common or diverse pattern(s) of its use.
For that purpose, a dataset was developed by analyzing 270 advise-giving ELLs’ essays from the EF-Cambridge Open Language Database for the use of modal devices by learners at elementary, intermediate and advanced proficiency levels; from China, Germany, and Brazil. Three main statistical analyses were performed: MANOVA, VanValen’s test, and Discriminant Function Analysis.
The results of this study indicate that the development of pragmatic knowledge of modality use is not a linear process; and that ELLs demonstrate common patterns of modality use regardless of the sociocultural background they belong to.
