Contact resistances in trigate and FinFET devices in a Non-Equilibrium Green's Functions approach
, 2016 We compute the contact resistances $R_{\rm c}$ in trigate and FinFET devices with widths and heights in the 4 to 24 nm range using a Non-Equilibrium Green's Functions approach.

Kinetic Compensation of Barrel Launch Under High‐Speed Solid‐Phase Particulate Impacts
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT An accurate launch‐dynamics computational method is critical for barrel weapon service life assessment and multiphase physics field refinement. Given the lack of studies on the solid‐phase buildup behavior at the projectile base, this paper provides an improved method for calculating the launching dynamics under high pressure and high speed ...

Impact of science objectives and requirements on probe mission and system design [PDF]
, 1974 Problem areas in probe science technology are discussed that require a solution before probe systems can actually be designed. Considered are the effects of the model atmospheres on probe design; secondly, the effects of implementing the requirements to ...

Shear viscosity and the r-mode instability window in superfluid neutron stars
, 2013 We analyze how recent computations of the shear viscosity $\eta$ in the core of superfluid neutron stars affect the r-mode instability window. We first analyze the contribution of superfluid phonons to the viscosity, both in their hydrodynamical and ...

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT This study explores the nonlinear dynamics associated with a passive dynamic walker (PDW), focusing on the bifurcation and stability insights derived from spring and damper mechanics. PDWs, which rely on gravity for stable locomotion without active control, exhibit a rich spectrum of behaviors, from periodic to chaotic motion.
