Second-order wave diffraction by horizontal rectangular barriers
(2011)
A complete second-order analytical solution for the nonlinear diffraction of waves by 2-D rectangular cylinders fixed at the free surface of finite-depth waters is presented. As a sequel to a previous linear treatment of ...
Multi Objective Design of Ships; A Pareto Procedure
(Springer Science and Business Media Deutschland GmbH, 2021)
The design calculations for a displacement type vessel and for a planing hull are done for the main dimensions, starting with a fuel and acceleration criteria. A large number of vessels are simulated with the help of ...
Three-parameter (3P) weibull distribution for characterization of strength of ceramics showing R-Curve behavior
(Elsevier Sci Ltd, 2021)
Strength distribution of advanced ceramics is commonly characterized by two-Parameter (2P) Weibull distribution. However, deviation of strength distribution from 2P-Weibull distribution may occur in ceramics due to various ...
Analysis of the residual stresses and deformations during the autogenous GTAW process
(Emerald Group Publishing Ltd, 2021)
Purpose The gas tungsten arc welding (GTAW) process is a widely used process that produces quality weldments. But the high heat generation from the GTAW arc can cause extreme temperatures as high as 20,000 degrees C. The ...
Numerical simulation of pressure loss in porous media in oscillating flow
(World Scientific and Engineering Academy and Society, 2018)
In this study, the pressure loss in two types of porous media for both unidirectional and oscillatory flows is analyzed using commercial software Comsol©. The numerical results are compared with those obtained in the ...
Hydrodynamic aspects of oscillating flow through porous media consisting of steel spheres
(Springer International Publishing, 2014)
Hydrodynamic aspects of oscillating flow through porous media are investigated within the scope of this experimental work where water is used as the flow medium. Friction factors are found reducing the data of hydrodynamic ...
Spacetimes admitting the Z-symmetric tensor
(Natl Inquiry Services Centre Pty Ltd, 2020)
This paper aims to introduce the spacetimes admitting the Z-symmetric tensor. We investigate the properties of these spacetimes for a perfect fluid and a pressureless perfect fluid (a dust). Some theorems about the properties ...
Weighted approximation by q-Ibragimov-Gadjiev operators
(Univ Osijek, Dept Mathematics, 2020)
The present paper deals with a q-generalization of Ibragimov-Gadjiev operators, which were constructed by Ibragimov and Gadjiev in 1970. We study convergence properties on the interval [0, infinity) and obtain the rate of ...
An overview of wire arc additive manufacturing (WAAM) in shipbuilding industry
(Taylor & Francis Ltd, 2020)
Increasing competition in the international shipbuilding industry pushes the naval architect's pressure to reduce the costs of design and manufacturing of new buildings. Using newly developed Additive Manufacturing (AM) ...
An Integrated Approach to Increase Marine Transportation Safety in Harbor Areas
(Marine Technology Soc Inc, 2017)
The importance of marine transportation safety in harbors and waterways access has become a very serious governmental concern in recent years, with the holding of special conferences on major marine disasters, increasing ...
