Study of Laminated Composite MEMS and NEMS Performance in Nano Metric Operations [PDF]
Mechanics of Advanced Composite Structures, 2017 Precision of nano-metric operations is an important issue in nano-engineering studies. Several operative parameters might affect the quality of results. The parameters of the nano world are significant but not entirely controllable.

, 2006 We consider the perturbed harmonic oscillator $T_D\psi=-\psi''+x^2\psi+q(x)\psi$, $\psi(0)=0$, in $L^2(\R_+)$, where $q\in\bH_+=\{q', xq\in L^2(\R_+)\}$ is a real-valued potential. We prove that the mapping $q\mapsto{\rm spectral data}={\rm \{eigenvalues

The Core Composition of a White Dwarf in a Close Double Degenerate System
, 2011 We report the identification of the double degenerate system NLTT 16249 that comprises a normal, hydrogen-rich (DA) white dwarf and a peculiar, carbon-polluted white dwarf (DQ) showing photospheric traces of nitrogen. We disentangled the observed spectra

Electromechanical Performance of NEMS Actuator Fabricated from Nanowire under quantum vacuum fluctuations using GDQ and MVIM [PDF]
Journal of Applied and Computational Mechanics, 2017 The Casimir attraction can significantly interfere the physical response of nanoactuators. The intensity of the Casimir force depends on the geometries of interacting bodies. The present paper is dedicated to model the influence of the Casimir attraction

Numerical creep analysis of FGM rotating disc with GDQ method
Journal of Theoretical and Applied Mechanics, 2017 Rotating discs are the vital part of many kinds of machineries. Usually, they are operating at relatively high angular velocity and temperature conditions. Accordingly, in practice, the creep analysis is an essential necessity in the study of rotating discs. In this paper, the time dependent creep analysis of a thin Functionally Graded Material (FGM)
