Near Grazing Dynamics of Piecewise Linear Oscillators

Impacts in mechanical systems are ubiquitous.

Dynamics of Coin Tossing Is Predictable

The dynamics of the tossed coin can be described by deterministic equations of motion, but on the other hand it is commonly taken for granted that the toss of a coin is random.

ON THE CRUSHING OF OPEN-CELL FOAMS

Polynomial matrix factorization for broadband adaptive signal processing

This talk will outline some of my recent research into techniques for factorizing polynomial matrices.

SD Oscillators: Current State and Future Research Prospects

A higher gradient theory for solid mixtures and its application to microelectronic materials

Rotational Motion of Pendula Systems for Wave Energy Extraction

The main aim of this work is to investigate different planar base excitation schemes, with respect to energy extraction from a mechanical pendulum. Focus is placed on how each forcing configuration affects the stable rotational motion or stability boundaries associated with stable rotations.

Near Grazing Dynamics of Piecewise Linear Oscillators

Impacts in mechanical systems are ubiquitous. These can be intrinsic; such as suspension cables in bridges acting as one-sided springs, unintentional; such as lateral 'Hunting' motions of trains causing loss of contact with the track, a result of wear or manufacturing errors; such as dead zones or gear rattles or...

Nonlinear Dynamics and control of an Autoparametric System with a Pendulum

Vibrations of an autoparametric system, composed of nonlinear mechanical oscillator with an attached damped pendulum, around 1:2 resonance region, are investigated in this work.

Hysteretic effects in dry friction: Experiment and Modeling

New type of static friction model containing hysteresis is presented.
