Actuators, 2023 Vibration-control techniques generally fall into two categories: passive methods that optimize the structure of the suspension to absorb any impact from the ground, and active methods that directly control the vertical force of the suspension by ...

Trapping dust particles in the outer regions of protoplanetary disks [PDF]
, 2011 Aims. We attempt to explain grain growth to mm sized particles and their retention in the outer regions of protoplanetary disks, as observed at sub-mm and mm wavelengths, by investigating whether strong inhomogeneities in the gas density profiles can ...

Improvement of Boeing Bump Method Considering Aircraft Vibration Superposition Effect
Applied Sciences, 2021 Pavement evaluation is critical for the decision-making process of pavement preservation and rehabilitation. Roughness is a key airport pavement characteristic that has been linked to impacts such as safety and service life. The Boeing Bump is one of the

Map++: A Crowd-sensing System for Automatic Map Semantics Identification
, 2015 Digital maps have become a part of our daily life with a number of commercial and free map services. These services have still a huge potential for enhancement with rich semantic information to support a large class of mapping applications. In this paper,

Dust Evolution and the Formation of Planetesimals
, 2016 The solid content of circumstellar disks is inherited from the interstellar medium: dust particles of at most a micrometer in size. Protoplanetary disks are the environment where these dust grains need to grow at least 13 orders of magnitude in size. Our

Multi-field Inflation with a Random Potential [PDF]
, 2009 Motivated by the possibility of inflation in the cosmic landscape, which may be approximated by a complicated potential, we study the density perturbations in multi-field inflation with a random potential.

Stellar irradiated discs and implications on migration of embedded planets I: equilibrium discs
, 2012 The strength and direction of migration of low mass planets depends on the disc's thermodynamics. In discs where the viscous heating is balanced by radiative transport, the migration can be directed outwards, a process which extends the lifetime of ...

Bump Modeling and Vehicle Vertical Dynamics Prediction
Advances in Mechanical Engineering, 2014 During a journey, motor vehicles are subjected to different types of irregularities in the pavement. Some of these irregularities are introduced for a specific purpose over a stretch of road to slow down the vehicle at certain road points.

Dynamical Synapses Enhance Neural Information Processing: Gracefulness, Accuracy and Mobility
, 2012 Experimental data have revealed that neuronal connection efficacy exhibits two forms of short-term plasticity, namely, short-term depression (STD) and short-term facilitation (STF).
