Effects of the intrinsic three-dimensionalization of laminar separation bubbles on the amplification of external disturbances
(2018-01-01)
The size and behavior of laminar separation bubbles is strongly related to the laminar-to-turbulent transition process that takes place downstream of the separation of the laminar boundary layer. Wind-tunnel experiments ...
A SEMI-ANALYTICAL APPROACH TO STUDY RESONANCES EFFECTS ON THE ORBITAL MOTION OF ARTIFICIAL SATELLITES
(Univelt Inc, 2013-01-01)
A semi-analytical approach is proposed to study resonances effects on the orbital motion of artificial satellites or space debris orbiting the Earth. Applying successive Mathieu transformations, the order of dynamical ...
New method for observing self-heating effect using transistor efficiency signature
(Ieee, 2017-01-01)
This paper reports a new method for observing the presence of self-heating effect through transistor efficiency (gm/ID) signature from DC measurements, for fast and accurate analysis. This new method is tested first through ...
A Negative-Bias-Temperature-Instability Study on Omega-Gate Silicon Nanowire SOI pMOSFETs
(Ieee, 2019-01-01)
The Negative-Bias-Temperature-Instability (NBTI) is an important reliability parameter for advanced technology nodes. This work presents an experimental study of NBTI in omega-gate nanowire (NW) pMOSFET. The 3D-numerical ...
Stable propagation of orbital angular momentum modes in pedestal waveguides
(2018-01-01)
We use numerical simulations to show that, even under common perturbations such as waveguide bends, pedestal waveguides are suited for stable propagation of modes carrying orbital angular momentum (OAM) in integrated devices.
Multi-layers Lateral SOI PIN Photodiodes for Solar Cells Applications
(Ieee, 2019-01-01)
In this paper, a lateral PIN photodiode based on a SOI wafer has been studied through numerical simulations. This device can be used as a solar cell embedded in a CMOS circuit in order to propose autonomous ultralow-power ...
Addendum to: Convergence towards asymptotic state in 1-D mappings: A scaling investigation [Phys. Lett. A 379 (2015) 1246]
(2015-05-16)
An analytical description of the convergence to the stationary state in period doubling bifurcations for a family of one-dimensional logistic-like mappings is made. As reported in [1], at a bifurcation point, the convergence ...
Optimising geometry and asymmetrical damping ratio to reduce vehicle vertical acceleration under stochastic road profile
(2018-01-01)
This work presents a study on the dynamic behaviour of a vehicle suspension system with asymmetrical viscous damping, with stochastic road profile. The geometrical configuration of a double-wishbone suspension system is ...
Optimising geometry and asymmetrical damping ratio to reduce vehicle vertical acceleration under stochastic road profile
(Katholieke Univ Leuven, Dept Werktuigkunde, 2018-01-01)
This work presents a study on the dynamic behaviour of a vehicle suspension system with asymmetrical viscous damping, with stochastic road profile. The geometrical configuration of a double-wishbone suspension system is ...
MODE SATURATION, MODE COUPLING AND ENERGY HARVESTING FROM AMBIENT VIBRATION IN A PORTAL FRAME STRUCTURE
(Amer Soc Mechanical Engineers, 2014-01-01)
There has been much recent interest in the concepts of electro-mechanical systems that are able to scavenge, or harvest energy from their operating environment. Here, we present the extraction of energy from a simple portal ...
