Study of Effect of Shape, Size and Symmetry on Electronic States of Some Three-dimensional Structures in Mesoscopic Size Regime
Abstract: This study presents theoretical study of effect of size and symmetry of different shaped three-dimensional GaAs structures in mesoscopic size regime. The effective mass Schrӧdinger equation is used in various shapes and its solution are modified as a function of volume and aspect ratio of structures. The calculated energy eigenvalues for square prism, equilateral prism, regular tetrahedral, cylindrical and spherical are comparatively analyzed to observe the effect of shape, size …

Group-Theoretic Symmetry Indices for Modular Building Layouts under Seismic Load Redistribution
Abstract: Symmetry in modular buildings operates simultaneously as an architectural language, a structural regularizer, and a computational design variable. This paper develops a group-theoretic framework for evaluating and optimizing plan symmetry in modular buildings subjected to seismic load redistribution. The building layout is modeled as a finite occupancy–stiffness field defined on a rectangular lattice, where each module encodes both mass and stiffness contributions. Planar reflections and quarter-turn rotations are represented as …

Analysis of Heat Transfer in a Heat Exchanger with Triangular Fins Using Finite Element Modeling
Abstract: The influence of radiation and convection on a catalytic reactor's triangular heat exchanger fins are examined. Heat escapes from the surface by radiation and convection having being transported by conduction throughout the fin. Convection and radiation enable the fin's tip to lose heat, whereas the base of the fin is kept at a constant high temperature. One of the walls is taken for consideration because of its symmetry and ease …

Dynamic Response Analysis of Isotropic and Orthotropic Rectangular Plates under Clamped-Free Conditions
Abstract: This study explores Theoretical and numerical tools of determining the free vibration properties of isotropic and fiber-reinforced composite rectangular plates. The effect of anisotropy of materials on the dynamic response of the plates is compared between the Aluminium plates and the glass-epoxy laminates. The model used in the study is a three-dimensional finite element model that is designed using a combination of SolidWorks and ANSYS workflow. Clamped-free boundary conditions are …

Influence of Gd Doping in Structural, Morphological and Optical Properties of Zno Nanostructures Synthesised Via Sol-Gel Processes
Abstract: In this study, nanocrystalline Zn1-xGdx (x=0.0 and 0.03) samples were synthesised via the Sol-gel combustion process. An array of analytical techniques was employed to examine the prepared samples to determine their different physical features. For both pristine and Gd-doped samples, the crystal symmetry is hexagonal with the P63mc space group which is verified via the Rietveld refinement analysis of X-ray diffraction (XRD) data. The atoms' bond length Zn-O and bond …

Structure and Crystal Growth of Urea Doped P- Block Element
Abstract: Nonlinear optical (NLO) materials exhibiting second harmonic generation have attracted considerable attention over the past few decades because of their technological significance in areas such as optical communication, signal processing, and instrumentation. Urea, being an important NLO material, presents challenges in crystal growth and handling due to its highly hygroscopic nature. Various derivatives of urea have been investigated for NLO applications, and some have shown promising potential in this field. …
