Comparison of blast analysis methods for modular steel structures
(Turkish Chamber of Civil Engineers, 2018-03)Two blast analysis methods widely used are three-dimensional finite element (FE) and uncoupled equivalent single degree of freedom (ESDOF) methods. The uncoupled equivalent ESDOF method, which is the most common blast ... -
Comparison of computational intelligence models on forecasting automated teller machine cash demands
(Old City Publishing, 2020)We take up the problem of forecasting the amount of money to be withdrawn from automated teller machines (ATM). We compare the performances of eleven different algorithms from four different research areas on two different ... -
Comparison of DC-link capacitor types under various grid conditions
(IEEE, 2019-04)A DC/AC converter can face negative conditions of power systems such as instability. One of the most crucial necessities of the grid is voltage stability. There are some effects of voltage unbalance for grid-tied DC/AC ... -
Comparison of nonlocal nonlinear wave equations in the long-wave limit
(Taylor & Francis, 2020-11-17)We consider a general class of convolution-type nonlocal wave equations modeling bidirectional nonlinear wave propagation. The model involves two small positive parameters measuring the relative strengths of the nonlinear ... -
A comparison of solutions of two convolution-type unidirectional wave equations
(Taylor and Francis, 2023)In this work, we prove a comparison result for a general class of nonlinear dispersive unidirectional wave equations. The dispersive nature of one-dimensional waves occurs because of a convolution integral in space. For ... -
Comparison of synthetic and steady air jets for impingement heat transfer over vertical surfaces
(IEEE, 2012)Natural convection air cooling is the method of choice for many low-power electronics applications due to cost, availability, and reliability considerations. This method is not only limited to low-power applications, but ... -
Comparison of text-independent speaker verification systems in a multi-class, semi-automatic detection scenario
