Formation Process of Acoustophoretic Patterns
The acoustic radiation force is a nonlinear wave effect that exerts a non-zero time- averaged force on objects in the wave. In recent years, the acoustic radiation force has been widely explored for manipulating objects and small particles. These applications range from moving a few objects at a …

Wave-current interaction in water of finite depth
In this thesis, the nonlinear interaction of waves and current in water of finite depth is studied. Wind is not included. In the first part, a 2D theory for the wave effect on a turbulent current over rough or smooth bottom is presented. The logarithmic profile of the basic current is modified by …

The impact of wave-modified wind stress in an ocean circulation model
A wave-related momentum flux parametrization is introduced in the ocean circulation model HYCOM. The physical process driving this parametrization is the growing and dissipation of the surface wave field. Two numerical experiments are conducted for the South Atlantic: one with the new wave effect …

Reconfigurable phased microstrip antenna array with defected ground structure and defected microstrip structure for beam steering application
… structure (DMS), which due to their slow wave effect and band-stop property, are able to disturb surface current distribution, then change the element phase and hence steer the main beam. This work started with investigating and applying new method for beam steering based on using DGS and …

Standard and Anomalous Wave Transport Inside Random Media
<p>This thesis is a study of wave transport inside random media using random matrix theory. Anderson localization plays a central role in wave transport in random media. As a consequence of destructive interference in multiple scattering, the wave function decays exponentially inside random …

Internal Resonances in Vibration Isolators and Their Control Using Passive and Hybrid Dynamic Vibration Absorbers
… the foundation are two criteria used to show the effects and significance of the IRs on isolator performance. Passive and hybrid DVAs embedded in the isolator are investigated to suppress the IRs. In the passive approach, two DVAs are implemented and their parameters are selected so that the IRs …

Improving Steering Module Efficiency for Incremental Loading Finite Element Numeric Models
Engineers frequently use computerized numeric models to calculate and predict water levels and current patterns for rivers, bays, and other bodies of water. This computation often involves an iterative process known as incremental loading that can cause frustration and consume a lot of time. …
