Nonlinear Amplification of Extreme Climate-Carbon Cycle Events
… in a general manner. Our analysis suggests that nonlinear amplifications have contributed substantially to many past climate-carbon cycle disruptions. The study of the mechanisms driving these disruptions becomes an valuable case study for the evolution of human-driven climate change. Better …

Large gain amplification mechanism for piezoelectric actuators utilizing a rolling contact joint
… practice is to use some form of displacement amplification mechanism. An efficient, heavy-duty displacement amplification mechanism for piezoelectric stack actuators is presented in this thesis. The displacement amplification gain is increased by a factor of more than 100 in a single stage by …

Orbital angular momentum and fully structured light in nonlinear media and cavities
… between high intensity laser light and nonlinear matter. By changing the structure of light's properties such as intensity and polarisation as well as the type of nonlinear action that occurs during propagation through the medium, we aim to describe how the properties of light are …

Nonlinear site amplification functions for Central and Eastern North America
Site amplification functions are used to modify ground motions from a reference bedrock condition to a surface condition based on the geologic features of the site of interest. Site amplification has been extensively studied and evaluated empirically for seismic regions such as the Western United …

Adaptive Digital Predistortion with Applications for LMDS Systems
… A background on LMDS link design, non-linear amplification, and predistortion is presented to assist the reader. A developed simulation uses AM-AM and AM-PM characteristics obtained from laboratory measurements of a 28 GHz amplifier to determine the effect of several predistortion …

Shear flow instabilities in stratified magnetohydrodynamics
… the astrophysically relevant case. Using weakly nonlinear theory, we derive amplitude equations for the two cases of Pe,Rm∼O(1) and Pe,Rm»1, where Pe (the ratio between thermal convection and thermal diffusion) and Rm (the ratio between magnetic induction and magnetic diffusion) denote the Péclet …
