The metaphysical doubts attempt to cast doubt on beliefs based on present or recollected clear and distinct perceptions. This paper clarifies the intension of the metaphysical doubts by answering the question of how an omnipotent God/Deceiver might exercise a deceptive influence on clear and distinct perception. My analysis shows： （1） the memory interpretation and the retrospective interpretation to be implausible; （2） the incoherence interpretation to be ill-founded, though its conclusion is partly right, such that we should accept a weaker version of it; （3） the misrepresentation interpretation, the defective-origin interpretation, the truth-value variation interpretation and the radical interpretation to be plausible; （4） all of these credible interpretations to be compatible with each other as well.展开更多

The Laplace and Fourier transforms technique have been employed to solve the model consisting of partial dif- ferential equations and boundary conditions in the transformed domain. In order to obtain the results in the physical domain the quadratic complex polynomial characteristic equation corresponding to the associated system of coupled ordinary differential equations has been solved by using DesCartes’ algorithm with the help of irreducible Cardano’s method. The inverse transform integrals are evaluated by using numerical technique consisting of Fourier series approximation and Romberg integration. The temperature change, stresses and electric potential so obtained in the physical domain are computed numerically and presented graphically for cadmium selenide (CdSe) material. The study may find applications in smart structures, pie- zoelectric filters, resonators, transducers, sensing devices and vibration control.展开更多
