Purpose This study aims to examine the plane wave reflection problem in micropolar orthotropic magneto-thermoelastic half space, considering the influence of impedance as a boundary in a nonlocal elasticity. Design/methodology/approach This study presents the novel formulation of governing partial differential equations for micropolar orthotropic medium with impact of nonlocal thermo-elasticity under magnetic field. Findings This study provides the numerical results validation for a particular numerical data and expression for the amplitude ratios of reflected waves and identifies the existence of four different waves, namely, quasi longitudinal displacement qCLD-wave, quasi thermal wave qCT-wave, quasi transverse displacement qCTD-wave and quasi-transverse micro-rotational qCTM-wave. The study derives the velocity equation giving the speed and phase velocity of these waves. The study also shows that the small-scale size effect gives significant impact on phase velocity. Research limitations/implications The graphical analysis examines the variation of speeds and coefficients of attenuation of these waves due to frequency, magnetic field and nonlocal parameters. Also, significant conclusions on the variation of reflection coefficient against nonlocal parameter, frequency, impedance parameter and angle of incidence are provided graphically. Practical implications The creation of more effective micropolar orthotropic anisotropic materials which are very useful in the daily life and their applications in earth science are greatly impacted by the findings of this study. Originality/value The authors of the submitted document initiated and produced it collectively, with equal contributions from all members. - Influence of Gravity and Hydrostatic Initial Stress on Wave Propagation in Context of Three Phase Lag Thermoelasticity

This paper examines plane wave propagation with initial stress and magnetic field in nonlocal dual-phase-lag in anisotropic thermo-elastic solid half-space. By Solving the governing equations in the x-y plane, we find the existence of three plane waves. Three non-homogeneous equations in the reflection coefficients of reflected waves are produced by this research's investigation of the reflection of such waves in plane form, through thermally insulated and isothermal stress-free surfaces. The nonlocal dual-phase-lag thermo elastic solid half space is used to calculate the phase velocity, specific loss, attenuation coefficient, and reflection coefficient for a given material. The variation in frequency and nonlocal parameter, as well as the reflection coefficient, phase velocity, attenuation coefficient, and specific loss, are graphically shown using the MATLAB application. - Enhancing Heart Disease Prediction with Ensemble Deep Learning and Feature Fusion in a Smart Healthcare Monitoring System

Abstract The research problem aims to investigate the effect of heat and moisture on the propagation of plane waves in a micropolar hygro-thermoelastic medium. The governing equations of a hygro-thermoelastic micropolar medium are developed and solved to determine the velocity equation. The plane-wave solution reveals that the medium is propagated by two coupled transverse displacement waves, namely Coupled Transverse Micropolar wave (CTM-wave) and Coupled Transverse Displacement wave (CTD-wave). Additionally, three coupled longitudinal waves are observed: thermal diffusion TD-wave, longitudinal displacement P-wave, and moisture diffusion mD-wave. To assess the characteristics of these waves in the micropolar hygrothermal medium, the speed and distance of propagation are calculated for each wave type. This analysis provides information on how fast and how far the P-wave, TD-wave, mD-wave, CTM-wave, and CTD-wave can travel in the medium. Furthermore, the research problem determines the equations for the coefficient of reflection and energy ratio when a coupled plane wave is incident on the medium. These coefficients quantify the amount of reflected energy compared to the incident energy and provide insights into the wave behavior at the interface of the medium. Finally, the variations in energy ratio and reflection coefficient are depicted graphically, allowing for a visual representation of how these quantities change with different parameters or conditions. These graphs provide a comprehensive understanding of the wave behavior and the effects of heat and moisture on the propagation characteristics in the micropolar hygrothermal medium. - Gravitational Effect on Piezo-Thermoelasiticity in the Context of Three Phase Lag Model with Two Temperature

The problem of plane waves in nonlocal fractional-order thermoelasticity has been studied. We have considered the x-y plane for the governing equation of nonlocal fractional thermoelasticity and solved these governing equations to calculate the equation in terms of frequency. This frequency shows that three sets of waves exist, in which two are coupled and one is uncoupled. The reflection coefficient of plane waves for classical theory and LS theory has been calculated. The effect of phase speeds, specific losses, and attenuation coefficients with respect to the frequency and nonlocal parameter for the two theories (LS theory and the classical theory of thermoelasticity) has been studied numerically for all propagating waves, and the same has been plotted graphically and explained thoroughly. - Fault-resilient localization using fuzzy logic and NSGA II-based metaheuristic scheme for UWSNs

In this present work, we consider the governing equations of Rayleigh wave with rotation, and two-temperature in the context of DPL with impedance boundary conditions in generalized micropolar thermoelastic half-space. We solved the governing equation by using surface wave techniques and satisfying the suitable radiation conditions and obtained the frequency equation. Impact of rotation, two-temperature, initial stress with IBC are computed numerically. The impact of various parameters against dimensionless speed have been shown graphically. - Influence of gravity and initial stress on rayleigh wave propagation in magneto-thermoelastic medium
