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) ...
Production and characterization of recycled polyester (r-PET) blend vortex and ring spun yarns
(Taylor & Francis Ltd, 2020)
Nowadays, many major fashion brands are now producing recycled polyester (r-PET) textile products from PET bottles to contribute to sustainability. Of course, this means that textiles containing r-PET will now be produced ...
Predicting air permeability and porosity of nonwovens with image processing and artificial intelligence methods
(Taylor & Francis Ltd, 2020)
This study was conducted to investigate the relationship between the fiber distribution and the permeability properties of the hydroentangled nonwoven fabrics in terms of air permeability and porosity. The fiber distribution ...
Z-symmetric manifold admitting concircular Ricci symmetric tensor
(Springer Heidelberg, 2020)
This paper deals with Z-symmetric Riemannian manifolds with concircular Ricci symmetric tensor. In the first section, we give an introduction of Z-symmetric manifold. In the second section, the definition of concircular ...
Investigation of formability of HC380LA material via the TPIF-RL incremental forming method
(Taylor & Francis Ltd, 2020)
Prototype parts can be produced rapidly and at low cost using the incremental forming method. The most important problem with this method is that it causes undesirable variations in wall thickness. Various methods have ...
Numerical modeling of friction stir welding using experimental temperature data
(Ice Publishing, 2020)
In this study, time-dependent heat-transfer analysis of friction stir welding of AA 6061-T651 plates was carried out. For this purpose, the Comsol code was utilized, by which the domain was modeled as a rectangular aluminum ...
Development of an Algorithm to Determine the Liquid Spreading Area of Airlaid Nonwoven Fabrics by Image Processing Method
(Ege Univ, 2020)
Today, many quality controls processes that are controlled by Image Processing (IP) technique has achieved state-of-the-art performance for all technology field. The image processing technique, which provides as accurate ...
