Authors: Premi M.S.Godwin , Sheeba G.Merlin , Livinsa Z.Mary , Valantina G.Mary 
Published: April 2021

Abstract
Human has needed and used energy at an increased rate for their various uses. As a result, huge amount of energy is exhausted and lost. Our objective is to harvest energy from the vehicle with or without load using mechanical gear system and to increase the efficiency level of the energy. The gear system will make the generator rotate, thus producing energy. This work is a real-time work as lot of vehicles moving daily will cross over the setup, generating efficient amount of electrical energy. It is an eco-friendly system as it doesn’t harms anything. It is a conventional power generation system when compared to existing systems. The work deals with the design of the model in real-time of the energy harvester using gear arrangements and increase in efficiency level of energy. The most challenging part in this assignment is the material that is to be used as top plate assembly, such that it can absorb heavy loads like buses, trucks with water tanks etc. Below the plate there are springs in which deformation will take place. The gear assembly is connected to the bottom of the spring through its teeth. When the spring gets deformed due to load, the gear assembly will be rotated which in turn will rotate the generator as it is coupled to the gear assembly. So energy will be produced. To increase its efficiency, gear assembly consisting of different sizes of gears, is used to increase the rotation of the generator which will produce more electrical energy. Generally, the output will be AC (alternating current), so AC to DC (direct current) converter is used. Amplifiers can also be used to make the energy more efficient and store it in battery for further application.

Authors: David Vincent Daniel , Bahar Arifah , Aziz Zainal Abdul 
Published: April 2021

Abstract
This research examined the critical flow over an uneven bump using forced Korteweg-de Vries (fKdV) model. The forced KdV model containing forcing term which represent an uneven bump is solved using Homotopy Analysis Method (HAM). HAM is a semi-analytic technique whereby its solution contains a series of approximated solution in which it converges immediately to the exact solution. A particular HAM solution is chosen with an appropriate convergence parameter by referring to horizontal line segment. The convergent HAM solution depicts that waves only exhibited over the sloping region and no rise of waves found on flat part of bottom topography.

Published: April 2021

Abstract
The objective of this paper is to study the flow patterns around mangrove roots to understand its significance in coastal risk reduction. A computational model of two-dimensional Pneumatophores mangrove roots is developed, and flow is simulated using ANSYS software with a predefined mathematical model and boundary conditions. Computational fluid dynamic analysis of a two-dimensional, viscous, incompressible, turbulent flow under steady and unsteady boundary condition is performed using the Finite volume method. Detailed velocity profiles, residual plots, pressure distributions, vectors of the velocity magnitude and pressure and velocity at different positions around the mangrove roots are presented to visualize the importance of mangroves in reducing the wave velocity. The simulation outcome confirms that the mangrove roots of mangrove species can reduce the initial velocity of water flow. The flow patterns and flow structures around the root in the mangrove forest establishes precious data in increasing the effectiveness of current breakwater model.

A Study on Exponential and Linear Density Stratification on Rectangular Channel Problems
Authors: Venkatesh L. Prasanna 
Published: April 2021

Abstract
In this paper we analyze viscous oscillatory MHD inhomogeneous fluid flow through the rectangular channel with one wall being porous through which suction or injection is taken place with constant rate and the other wall being rigid. The density function in the equation of incompressibility are considered in first case as exponentially distributed and that in the second case as linearly distributed. The governing equation of motion in both cases are solved using similarity transformation and the graphical representation in both cases are analyzed and compared for velocity profiles. Further for second-degree approximation, the exponential stratification reduces to the results of linear stratification results, which are already available in the literature.

Authors: Osman R , Ramli N , Badaruddin Z , Ayub H , Karim S N A Syed Abdul 
Published: April 2021

Abstract
The issues related to students’ expectation on the learning of mathematics is considered crucial because one can never decide the appropriate educational path that suits the students according to what they are supposed to study and should engage in the learning process. This study performed analysis on the secondary data of a previous research conducted on students’ expectation on the learning of mathematics. Due to the vague and imprecise human judgment and preference, fuzzy approach is used in this study. The fuzzy conjoint method based on fuzzy set is being widely used to analyse human preference. However, the method cannot produce the weight of attribution in various degrees of confidence. The aim of this study is to improve fuzzy conjoint method based on trapezoidal fuzzy number and investigate the students’ level of preferences on the learning of Mathematics and to compare the result with the secondary data. Hence, by incorporating fuzzy number in continuous form, it will enable the respondents to express their opinion in a more detailed interpretation. This study improvised the existing procedure by employing trapezoidal fuzzy number in representing the predefined linguistic terms and the aggregation of preference level of the respondents based on each criterion. The highest priorities of degree of agreement for students’ expectation is lecturers should focus more on developing and understanding the concept of learning mathematics, followed by student-lecturer interaction and lecturers and lecturers should have sufficient time to complete all the syllabus.

Inverse fuzzysoft set theory is an extension of fuzzy soft set theory which gives deeper insights in decision making and gives a technique to portray the character of each object in the universe. An application of inverse triangular and trapezoidal fuzzy soft set is established in the course of case study in multi-criteria decision making.
Integration of Sorensen and Cosine Similarity Measure for Solving Fuzzy Decision Making Problems
Authors: Mohamad Daud , Suboh Nurmaizatul Nabilah 
Published: April 2021

Abstract
Similarity measure has been used in many fields of study to measure common features between objects. The fuzzy similarity measure is popularized when elements of vagueness and subjectivity are incorporated in the comparison process. It is a preferred approach to some distance methods since in obtaining the distances, the defuzzification process will be involved that may cause loss of some vital information due to simplification process to a single value. Several fuzzy similarities have been proposed to cater different setting and for better discrimination. Nevertheless, in many cases, an extreme degree of similarity may occur due to the characteristic of the similarity measure itself. In particular, the Cosine similarity measure gives a too low degree of similarity while the Sorensen similarity measure gives a too high degree of similarity where in return the utilization of these similarities may not give the acceptable measurement of similarity. An integration of two or more similarity measures may assist to eradicate this problem. In this paper, the Sorensen and Cosine similarity measure were integrated based on the variation coefficient representation under fuzzy environment. A procedure of ranking alternatives is proposed using the new integrated similarity measure and is used to solve the grading problem of oil palm fruit bunch. The proposed integrated fuzzy similarity measure of Cosine and Sorensen has an advantage of being able to compromise the extreme values produced by the two similarity measures and has the potential to be applied to solving various fuzzy decision making problems.

Codes in Rosenbloom-Tsfasman metric: A Survey
Authors: Gopinadh Bodigiri Sai , Marka Venkatrajam 
Published: April 2021

AbstractThis paper gives a systematic survey of research carried out in the theory of codes equipped with Rosenbloom-Tsfasman metric. In classical coding theory setting, codes are investigated with respect to the Hamming metric which can efficiently address the communication problems arising from channels in which channel noise generates equiprobable errors. But however, not all the real world channels are of that nature, especially, when the possible errors form patterns of a specific shape. Rosenbloom and Tsfasman introduced a non-Hamming metric, called Rosenbloom-Tsfasman metric (RT-metric, in short) that can address the problem of reliable information transmission over parallel noisy channels. Martin, Stinson and Skriganov independently introduced the same metric in the context of the theory of uniform distributions. As this metric happened to be a generalization of the classical Hamming metric, it has attracted so much attention from the coding theory research community and as a result a lot of work has been done in this line of research over the past 3 decades. In this paper we would like to present the key developments in the field of codes with RT-metric.

Abstract
The ground-state properties and optical, mechanical, elastic and thermal properties of the Ca0.875Ba0.125Te alloy have been studied by using the full potential linearized augmented plane wave (FP-LAPW) scheme based on the density functional theory in the frame of generalized gradient approximation (GGA). In order to model Ca1-xBaxTe alloy, 16-atoms supercell of the type 2 × 2 × 2 is employed. The lattice structure of Ca0.875Ba0.125Te alloy is obtained by replacing one Ca atom by one Ba atom in the crystal lattice of CaTe. The charge density plot, electronic structure and density of states plots are made and discussed for the alloy. The lower valence band maxima (VBM) and the upper conduction band minima (CBM) of Ca0.875Ba0.125Te alloy is locaed at Γ point, ensuing in a direct band gap, whereas in case of parent element CaTe the nature of the band gap is indirect. The characteristic properties of Ca0.875Ba0.125Te alloy is dominated by Te 5p electrons (below the Fermi level) and Ba 4d and Ca 3d electrons (above the Fermi level).

Abstract
A novel semiorganic optical material, L-alanine doped urea thiourea magnesium chloride (ATUMC) single crystals has been synthesised by evaporating the mixture of solvents slowly at a temperature of 34 °C. XRD data of crystals AUTMC crystals show a slight change in the values of lattice parameters and volume in comparison with the pure urea thiourea magnesium chloride (UTMC) crystal indicating the inclusion of dopant alanine. The vaious interaction among elements present in the grown sample was elucidated using FT-IR studies. n UV studies has confirmed an absorption between 292 –1000 nm region. By adding alanine as dopant the absorption region lies in the same region. NLO property is also analysed for the grown crystal using Kurtz Perry method. The TG/DTA analyses show that the thermal stability is considerably increased with the addition of alanine dopant in the pure TUMC crystal.
