Partial Smoothness, Tilt Stability, and Generalized Hessians [PDF]
SIAM Journal on Optimization, 2013 We compare two recent variational-analytic approaches to second-order conditions and sensitivity analysis for nonsmooth optimization. We describe a broad setting where computing the generalized Hessian of Mordukhovich is easy. In this setting, the idea of tilt stability introduced by Poliquin and Rockafellar is equivalent to a classical smooth second ...

Stability of a tilt-controlling axial gap self-bearing motor with single-stator
Mechanical Engineering Journal, 2017 This paper discusses the stability of a tilt-controlling axial gap self-bearing motor with a single stator. The motor consists of a stator and a disc rotor and is capable of controlling motor torque, axial position, and tilt angles.

Telehandler Stability Analysis Using a Virtual Tilt & Rotation Platform
MachinesThis paper investigates the stability of telehandlers operating on inclined terrain through a sequential methodological approach. In a first stage, stability is assessed using quasi-static methods based on force and moment equilibrium, including the load

Active optical table tilt stabilization [PDF]
Review of Scientific Instruments, 2020 We show that a simple modification to an optical table with pneumatic vibration isolation can be used to actively reduce the long term drift in the tilt of the table by nearly a factor of 1000. Without active stabilization, we measure a root-mean-square (rms) tilt variation of 270 µrad over three days.

Energies, 2022 A solar dish concentrator system has a large windward area and heavy structural mass, and under the action of wind loads and self-weight loads, foundation settlement can easily occur and cause the column (the azimuth axis) to tilt.

Real and visually-induced body inclination differently affect the perception of object stability. [PDF]
PLoS ONE, 2017 The prediction of object stability on earth requires the establishment of a perceptual frame of reference based on the direction of gravity. Across three experiments, we measured the critical angle (CA) at which an object appeared equally likely to fall ...
