The interaction of shock waves and dispersive waves
We introduce and analyze a coupled system of partial differential equations which model the interaction of shocks with a dispersive wave envelope. The system mimics the Zakharov equations from weak plasma turbulence theory but replaces the linear wave equation in that system by a nonlinear equation …

Ridge waves
… of the modes it supports. In addition, the waves travelling along the flanks 'feel' the topography of the opposite side so t hat increasing the width or steepness of the eastern slope decreases the frequencies of the modes supported by the western side (and vice versa). The dispersion …

WALKING IN WAVES
… of two sections. The first section, “Walking in Waves,” is composed of stories about familial relationships and the balancing act of motherhood. Some of these stories play with unique formats or degrees of speculative fiction. Many are rather lyrical in nature. The second section is a …

Waves of Cement
Waves of cement is a collection of four short stories, all written in first person, and with varying themes. "Aspero Ranch" is a Western story about an unwelcoming dude ranch in the Rocky Mountains and the wranglers who work there; " Smoking and lying on the couch" is the story of a depressed man …

The Formation of Edge Waves Under Monochromatic and Random Incident Waves
Edge waves are coastal waves trapped near the shore by reflection and refraction. Previous studies show the excitation mechanism of edge waves under monochromatic wave conditions via phase locking and nonlinear growth. However, how efficiently the mechanism would work under random incident waves …

Practical localized waves generation
Since the early works on localized waves (LW), extensive results were published on this important subject, from both the theoretical and the experimental points of view. Nevertheless, those experimental techniques of LW generation suffer from several shortcomings. A major one is that only pulse …

Models for ocean waves
Ocean waves represent an important design factor in many coastal engineering applications. Although extreme wave height is usually considered the single most important of these factors there are other important aspects that require consideration. These include the probability distribution of wave …

Sources of localized waves
… representation, we find a new class of focused X Waves which can be extremely localized. The modified bidirectional decomposition is applied to the nonhomogeneous scalar wave equation, resulting in moving sources generating L W pulses. In this work, we also address the possibility of exciting L W …

Nonlinear spin waves in magnetic thin films - foldover, dispersive shock waves, and spin pumping
Three nonlinear phenomena of spin waves and the spin Seebeck effect in yttrium iron garnet (YIG)/Pt bi-layer structures are studied in this thesis and are reported in detail in Chapters 4-7. In the fourth chapter, the first observation of foldover effect of nonlinear eigenmodes in feedback ring …

Whistler Waves: Modeling and Observations
<p>The thesis presents the results of all the research from the published and in publication process research in the Journal of Geophysical Research [1]. This research focuses on whistler wave ducting events in the equatorial magnetosphere. High-density ducts are the main focus of whistler study in …
