Study of the Influence of Thermal Tempering on the Bending Behavior of the Silico Soda Lime Glass Material
Abstract: In this contribution, we examine the mechanical behavior of tempered soda-lime-silica glass plates and show that improvements in performance can be achieved through the change of the structural and mechanical properties. Tests of thermal tempering by air jet have been performed on glass plates of different dimensions. Three-point bending tests have been conducted on nontempered and fully tempered float glass plates of four different sizes. A parametric study on the …

Time and Frequency Response of Non-uniform Overhead Lines Under Corona
Abstract: This study presents an efficient and direct technique for determining both the time and frequency responses of non-uniform overhead power transmission lines operating under corona conditions. The assumed-line's non-uniformity is due to the conductors’ sag. Expressions will be presented for the location-dependent line surge impedance and the unevenly distributed lines’ electrical parameters. The analysis starts with solving the relevant system of differential and algebraic equations, subject to the boundary conditions. …

Introduction to Statistical Tests of Significance
Abstract: Hypothesis examination is the process in which we compare between two differing hypotheses. i.e. the null hypothesis H0 and the alternative hypothesis. As the null hypothesis is examined, a choice is either correct or incorrect. An incorrect conclusion can be produced in two methods: We can deny the null hypothesis once it is true (Type I error) or we cannot succeed to eliminate the null hypothesis when it is incorrect …

Thermo-Fluid Characterization of Corrugated U-Tube Shell-and-Tube Heat Exchanger with Polymer Composite Tube Wall: A Combined CFD and Experimental Investigation
Abstract: Shell-and-tube heat exchangers built with metallic tubes work well thermally, but corrosion problems, extra weight, and the inability to adjust the wall’s thermal properties through material choice remain genuine engineering headaches, particularly for corrosive or weight-critical applications. Over the past few years there has been a fair amount of interest in replacing metal tubes with polymer composite alternatives, since blending thermally conductive fillers — graphite nanoplatelets, boron nitride platelets and …
