Geoacoustic Inversion for a New England Mud Patch Sediment Using the Silt-Suspension Theory of Marine Mud

IEEE Journal of Oceanic Engineering, 2020
This article provides an application of the silt-suspension theory to a Bayesian-inference inversion for the geo-acoustic parameters in marine mud. The theory, with consequences that have been developed recently, postulates a suspension of water and clay mineral card-houses that supports moderately dilute concentrations of silt particles.

Geoacoustic parameter variations and inversion estimates with a silt-suspension theory of mud

The Journal of the Acoustical Society of America, 2018
Marine mud sediments can be modeled by a recent silt-suspension theory [Pierce, et al., JASA, 142, 2591 (2017) (A)], in which silt particles are embedded in a suspension of flocculated clay particles. This presentation investigates the influence on attenuation predictions from uncertainties in parameters such as the effective grain density and the ...

Prediction of silt soil subgrade moisture content based on unsaturated seepage theory

2011 Second International Conference on Mechanic Automation and Control Engineering, 2011
In order to study the distribution of water in silt soil subgrade, this paper establish finite element model based on unsaturated seepage theory to research the groundwater level, rainfall, evaporation factors influencing on the moisture content of subgrade and side slope materials.

Based on Fuzzy Theory to Model and Analysis about Global Stability of Seawall Established on Deep Silt

DEStech Transactions on Materials Science and Engineering, 2017
This article is based on Swedish circle method and Fuzzy theory and make assumptions to cohesion of silt C and internal frictional angle of silt those are the main random variable effecting the stability of whole seawall, then give the model of fuzzy reliability as a reference to be consulted in engineering.

Applications of a suspension theory of silt particles in mud to frequency and other parameter dependencies of geoacoustic quantities

The Journal of the Acoustical Society of America, 2017
A recent suspension theory of marine mud [Pierce, et al., POMA 29, accepted] hypothesizes that embedded silt particles are the dominant contributors to compressional wave attenuation. The approach predicts frequency intervals within which attenuation increases roughly linearly with frequency, as often assumed. These intervals depend on the measured (or

Tor-tilting and weak silting theories in comodule categories

Journal of Algebra and Its Applications
In this paper, we introduce and investigate Tor-tilting comodules and weak silting comodules, providing a generalization of the established tilting and silting theories in the comodule category. Our exploration yields a comprehensive understanding of their fundamental properties, including their associated torsion theories.

Theory of sound propagation through a fluidic medium with suspended clay and silt particles having the general characteristics of mud

The Journal of the Acoustical Society of America, 2019
Work presented at previous meetings and in various publications for propagation of sound through mud continues with a theory that simultaneously takes into account viscous flow past both suspended clay and silt particles. Why silt particles do not settle under the action of gravity to the bottom of the layer is explained because (1) the clay particles ...
