Existence of solutions to non-Homogeneous higher order Differential Equation in the Schwartz space
2018Co-Authors: V. H. Samoilenko, Yuliia SamoilenkoAbstract:There is studied problem on existence of solutions to non-Homogeneous Differential Equation of higher even order. Similar problem arises while studying soliton and soliton-like solutions to partial Differential Equations of integrable type. By means of Fourier transform and theory of pseudoDifferential operators there is proved the theorem on necessary and sufficient conditions on existence of solutions to linear non-Homogeneous Differential Equation of higher even order in the Schwartz space.

semi analytical solution for electromagnetothermoelastic creep response of functionally graded piezoelectric rotating disk
International Journal of Thermal Sciences, 2013Co-Authors: A Loghman, M Abdollahian, Jafarzadeh A Jazi, Ghorbanpour A AraniAbstract:Abstract Time-dependent electromagnetothermoelastic creep response of rotating disk made of functionally graded piezoelectric materials (FGPM) is studied. The disk is placed in a uniform magnetic and a distributed temperature field and is subjected to an induced electric potential and a centrifugal body force. The material thermal, mechanical, magnetic and electric properties are represented by power-law distributions in radial direction. The creep constitutive model is Norton's law in which the creep parameters are also power functions of radius. Using Equations of equilibrium, strain-displacement and stress–strain relations in conjunction with the potential-displacement Equation a non-Homogeneous Differential Equation containing time-dependent creep strains for displacement is derived. A semi-analytical solution followed by a numerical procedure has been developed to obtain history of stresses, strains, electric potential and creep-strain rates by using Prandtl–Reuss relations. History of electric potential, Radial, circumferential and effective stresses and strains as well as the creep stress rates and effective creep strain rate histories are presented. It has been found that tensile radial stress distribution decreases during the life of the FGPM rotating disk which is associated with major electric potential redistributions which can be used as a sensor for condition monitoring of the FGPM rotating disk.

Eigensolutions, scattering phase shift and thermodynamic properties ofHulthẻn-Yukawa potential
'Elsevier BV', 2019Co-Authors: Adebimpe O., Onate C.a, Salawu S. O., Abolarinwa Abimbola, Lukman A. F.Abstract:The amendibility of a spin-0 and spin-1 particle with a combined potential in the presence of the Duffin-Kemmer-Petiau wave Equation is highly recommendable. Thus, the approximate bound state of the Duffin-Kemmer-PetiauEquation and Schrӧdinger Equation were obtained with a combination of Hulthẻn and Yukawa potentials in theframework of asymptotic iteration method and parametric Nikiforov-Uvarov method respectively for any ar-bitrary angular momentum quantum numberJusing a suitable approximate scheme to the centrifugal term. Thiswas done when the second-order Homogeneous Differential Equation was transformed to a form of recurrencerelation from which a quantization condition obtained was used to calculate the eigenvalue energy Equation andthe corresponding wave function. In other to apply more application to this work, the scattering phase shift ofthe Duffin-Kemmer-Petiau Equation was calculated and the thermodynamic properties of the potential underconsideration were also calculated in view of the Schrӧdinger Equation. It is noted that the results obtained byvarying the two strengths of the potential differs due to the effect of the screening parameter
