Large amplitude driving of a persistent current qubit
… current qubit in the presence of large amplitude microwave radiation is studied. Three main results are presented in this work. A new coherent quasi classical regime has been observed, where coherent quantum dynamics persist even while transitions between energy levels are caused by many …

Elastic wave tailoring at the macro/micro/nano- scales using intentional strongly nonlinear coupling
… in the linear dynamic regime such as frequency-amplitude dependence, sudden transitions (jumps), bifurcations, saturation effects, internal resonances, and chaos. In this work we harness this nonlinear behavior in the form of nonlinear coupling in acoustic waveguides. Common methods of achieving …

Finite Element Procedures in Modelling the Dynamic Properties of Rubber
… dependent on strain rate, temperature and strain amplitude. The non-linear elastic property and the strain amplitude dependence give a non-linear dynamic behavior that is covered by the models suggested in this thesis. The focus is on a finite element procedure for modelling these dynamic …

Analysis of Linear and Nonlinear Quasiperiodic Metamaterials with Local Resonators
… both determined as a function of the excitation amplitude, with the results indicating a strong amplitude dependence for both. As the amplitude is increased, all modes experience a shift in frequency, which can result in loss of localization for some edge modes and the generation of breathers for …

An Exploration of Nonlinear Locally Resonant Metamaterials with Electromechanical and Topological elements
… features such as edge modes, resulting in amplitude dependence that can affect the localization of these modes in the nonlinear regime. Finally, a metamaterial with nonlinearity, electromechanical local resonators, and quasiperiodic patterning is modeled and investigated. Multiple …

Exploring the Limits of Boundary Element Methods for Wave Energy Converter Hydrodynamics
… to capture some behavior when viscous damping or amplitude dependence is present in the experimental data, and disagreements between BEM and experi- ments increase at higher frequencies. The comparison in BEM parameters across geometries indicates that there could be a connection between the …

Fiber Orientation Modeling: a Method to Improve Quantitation of Intramyocellular Lipids in Human Subjects at 7 Tesla
… was translated by the well-known orientation dependence interaction OMEGA = 3cos2THETA-1, where THETA is the angle between EMCL and the applied field. As the result, the location and amplitude of individual curves representing each strand could be derived. Depend on the aforementioned Gaussian …

Estimates of crustal transmission losses using MLM array processing
… layer, and iii) expanding the role of arrival amplitudes in inversion theory. Just as there may be a number of possib1e paths in the sea between a source and receiver, each with a different loss characteristic, trajectories in the crust are variegated and exhibit different TL behaviors. It is …

EXPERIMENTAL INVESTIGATION OF THE RESPONSE OF FLAMES WITH DIFFERENT DEGREES OF PREMIXEDNESS TO ACOUSTIC OSCILLATIONS
… strategy. Special emphasis was placed on the amplitude dependence of their response. Also, the behaviour of self-excited fully premixed flames was examined. kHz OH* chemiluminescence was used to study qualitatively the heat release response of the flames, while kHz OH Planar Laser Induced …
