Nonlinear Dynamic Model of M-EHA Considering Fluid Bulk Modulus Variation

Modulus Stabilization with Bulk Fields

We propose a mechanism for stabilizing the size of the extra dimension in the Randall-Sundrum scenario. The potential for the modulus field that sets the size of the fifth dimension is generated by a bulk scalar with quartic interactions localized on the two 3-branes. The minimum of this potential yields a compactification scale that solves the hierarchy problem without fine tuning of parameter...

A bulk modulus dependent linear model for acoustical imaging.

Modeling the acoustical process of soft biological tissue imaging and understanding the consequences of the approximations required by such modeling are key steps for accurately simulating ultrasonic scanning as well as estimating the scattering coefficient of the imaged matter. In this document, a linear solution to the inhomogeneous ultrasonic wave equation is proposed. The classical assumpti...

Fluid-Induced Nonlinear Dynamic Tensioning of Cables

The long-term goal of this research is to identify the dominant mechanisms that control the dynamic tension in submerged cables. This goal addresses the need to suppress or alleviate the dynamic component of cable tension that may adversely affect the performance of underwater cables and any mission they are used to support. For instance, large dynamic tension forces may degrade the positioning...

The bulk modulus of covalent random networks

We re-examine the calculation of the bulk modulus of random networks with a variable mean coordination 〈r〉 that ranges from 〈r〉 = 4 down through the phase transition from rigid to floppy that occurs at around 〈r〉 = 2.4. In contrast to previous workers, we use random-network models, rather than depleted diamond lattices, so our results are more relevant to glasses. We find that the bulk modulus ...
