A fast impulsive contact suite for rigid body simulation
IEEE Transactions on Visualization and Computer Graphics, 2004A suite of algorithms is presented for contact resolution in rigid body simulation under the Coulomb friction model: Given a set of rigid bodies with many contacts among them, resolve dynamic contacts (collisions) and static (persistent) contacts. The suite consists of four algorithms: 1) partial sequential collision resolution, 2) final resolution of ...

Fast-Impulse Nanothermite Solid-Propellant Miniaturized Thrusters
Journal of Propulsion and Power, 2013Highly reactive nanothermites prepared by mixing bismuth trioxide or cupric oxide nanoparticles with aluminum nanoparticles were evaluated as solid propellants for small-scale propulsion applications. Miniaturized engines were fabricated from steel in three-piece configurations without a converging/diverging nozzle.

Instrument Voltage Transformer time-response to fast impulse
2016 17th International Conference on Harmonics and Quality of Power (ICHQP), 2016Instrument Voltage Transformers (VT) are well known for their critical behavior when subjected to fast impulse voltages. Furthermore, the accuracy of VT is defined by IEC Standards only at power frequency and doesn't consider fast impulse response. Under these conditions the VT may introduce errors in voltage measurements and the transmitted signals ...

Characterization of Ionization Phenomena in Soils Under Fast Impulses
IEEE Transactions on Power Delivery, 2006Protective devices such as spark gaps and surge arresters are used to divert surges to earth. It is, therefore, necessary that earthing systems are designed with a low-magnitude earth impedance value so that the overvoltage protection devices can divert high fault currents effectively to earth for all types of fault. Power frequency characterization of

A fast impulsive noise color image filter using fuzzy metrics
Real-Time Imaging, 2005In this paper, the problem of impulsive noise reduction in multichannel images is addressed. A new filter is proposed on the basis of a recently introduced family of computationally attractive filters with a good detail-preserving ability (FSVF). FSVF is based on privileging the central pixel in each filtering window in order to replace it only when it

Design and Construction of a Compact Electrostatic Fast Impulse Current Generator
2005 IEEE Pulsed Power Conference, 2005A new version of a very fast impulse current generator based on the use a floating electrode was designed and constructed. The "Roman generator" is an electrostatic generator able to produce lightning-like current derivatives, with amplitude in the order of kA.

IEEE Transactions on Image Processing, 2001
A generic n-dimensional filter with the primary purpose of eliminating impulsive-like noise is presented. This recursive nonlinear filter is composed of two conditional rules, which are applied independently, in any order, one after the other. It identifies noisy items by inspection of their surrounding neighborhood, and afterwards it replaces their ...

2012 International Symposium on Intelligent Signal Processing and Communications Systems, 2012
Impulsive noise in a compressed measurement signal can be detected by the energy distribution of the reconstructed sparse signal. In this paper, the fast preprocessing for impulsive noise rejection for a compressed measurement image signal is proposed. An image is sparsified by octave-tree wavelet transform with db8 as the mother wavelet. The impulsive
