Two-dimensional quantum-spin-1/2 XXZ magnet in zero magnetic field: Global thermodynamics from renormalisation group theory
(Taylor & Francis Ltd, 2019)
Phase diagram, critical properties and thermodynamic functions of the two-dimensional field-free quantum-spin-1/2 XXZ model has been calculated globally using a numerical renormalisation group theory. The nearest-neighbour ...
A Detailed Analysis of Ideal Rankine Steam Cycle
(Amer Soc Naval Eng Inc, 2016)
In this theoretical work, the ideal Rankine cycle using water vapor is studied in detail considering a condenser pressure range of 10-80 kPa, a boiler pressure range of 3-15 MPa and a superheater temperature range of 350-600 ...
Search for heavy resonances decaying to a top quark and a bottom quark in the lepton plus jets final state in proton-proton collisions at 13 TeV
(Elsevier, 2018)
A search is presented for narrow heavy resonances decaying to a top quark and a bottom quark using data collected by the CMS experiment at root s= 13 TeV in 2016. The data set analyzed corresponds to an integrated luminosity ...
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 ...
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 ...
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 ...
Electrical, optical, and mechanical percolations of multi-walled carbon nanotube and carbon mesoporous-doped polystyrene composites
(Sage Publications Ltd, 2020)
In this study, we have investigated and compared electrical, optical, and mechanical properties of polystyrene thin films with added multi-walled carbon nanotube and carbon mesoporous. Surface conductivity (sigma), scattered ...
