Pippard relation close to the alpha - beta transition for quartz in granite
(American Institute of Physics, 2016)
In this study, we examine variation of the thermal expansion ?p with the isothermal compressibility KT at various temperatures (1 atm) close to the ?-ß transition in quartz using the experimental data from the literature. ...
Analysis of the thermal expansivity near the tricritical point in dilute chromium alloys
(American Institute of Physics, 2016)
Chromium (Cr) undergoes a first order Neel transition as an antiferromagnetic material. When V, Mo and Mn atoms are substituted in the Cr lattice, a weak first order Neel transition in pure Cr changes toward a second order ...
Calculation of the thermodynamic quantities of perovskite metal organics DMAKCr and perovskite HyFe close to the weakly first-order relaxor-like structural transformation using the mean field theory
(World Scientific Pub., 2019-04-30)
Weakly first-order or nearly second-order phase transitions occurring in metal{organic frameworks (MOFs), particularly in DMAKCr and perovskite HyFe, are studied under the mean field model by using the observed data from ...
Magnetic Transitions in Two Novel Mixed-Valence Iron(Ii)–Iron(Iii) Metal Formate Frameworks : Two Sublattice Model
(Elsevier B.V., 2022)
We study the two-sublattice model in the mean field theory by expanding the Gibbs free energy in terms of the magnetizations M1 (Mup) and M2 (Mdown) with the quadratic coupling M12M22 (quadrupolar interactions) for the ...
Surrogate Based Design Optimization of Multi-Band Antenna
(Institute of Electrical and Electronics Engineers Inc., 2021)
In this work, design optimization process of a multiband antenna via the use of Artificial Neural Network (ANN) based surrogate model and meta-heuristic optimizers is studied. For this mean firstly, by using Latin-Hyper ...
Gain Enhancement of a Traditional Horn Antenna using 3D Printed Square-Shaped Multi-layer Dielectric Lens for X-band Applications
(Applied Computational Electromagnetics Society (ACES), 2021)
In this work, gain of a traditional horn antenna is enhanced up to 2.9 dB over X-band using 3D printed square-shaped multi-layer lens. For this purpose, firstly the multi-layer lenses are designed using Invasive Weed ...
Calculation of the Liquid-Solid Phase Diagram and the Thermodynamic Quantities of the Binary System of Tetradecane and Hexadecane Using the Mean Field Theory
(Springer/Plenum Publishers, 2021)
The T - x phase diagram of a binary system of tetradecane + hexadecane is calculated using the Landau phenomenological model. Expressions derived for the phase lines are fitted to experimental data from the literature and ...
