The analysis of the structural, electronic, and optical properties of pure gallium nitride (GaN) and GaN doped with aluminium (Al) and tallium (Tl) was carried out using the FP-LAPW method. The generalized gradient ...

The process of hydrogen production from water using two-dimensional (2D) materials represents a vital research field for the development of clean and sustainable energy sources. This study aims to explore the structural ...

In this work, we studied the structural, elastic, and thermodynamic properties of the compounds Li_2TiBr_6 and Na_2TiBr_6 using Density Functional Theory (DFT). The calculations were performed using the Generalized Gradient ...

This master’s thesis analyzes the structural, electronic, and optical properties of GeS2 , GeO2 , and Janus GeSO monolayers in their trigonal crystalline form. Calculations, performed within the framework of density ...

In this work, we consider the limit cycles of a class of polynomial differential systems of the form {<K1.1/>┊ <K1.1 ilk="MATRIX" > u=v-ε(g₁¹(u)+f₁¹(u)v)-ε²(g₁²(u)+f₁²(u)v), v=-u-ε(g₂¹(u)+f₂¹(u)v)-ε²(g₂²(u)+f₂²(u)v), ...

This study employs the one-dimensional shooting method to numerically solve a boundary value problem (BVP) governed by an ordinary differential equation (ODE). Such BVPs arise in diverse scientific and engineering domains, ...

This thesis presents a novel numerical approach for solving nonlinear Fredholm integro-differential equations involving both the unknown function and its derivative. The proposed method combines the backward finite difference ...
