• #### A mode-matching analysis of dielectric-filled resonant cavities coupled to terahertz parallelplate waveguides ﻿

(2012-09-07)
We use the mode-matching technique to study parallel-plate waveguide resonant cavities that are filled with a dielectric. We apply the generalized scattering matrix theory to calculate the power transmission through the ...
• #### Model development for a highly sloped, limestone watershed to be used in a radar-based flood alert system ﻿

(2005)
Flood Warning Systems are not a new commodity to the hydrologic world, however, the advancements in GIS data, hydrologic modeling tools, NEXRAD, and internet capabilities have allowed for improvements in flood prediction. ...
• #### Model independent search for new phenomena in pp¯ collisions at s√=1.96  TeV ﻿

(2012)
We describe a model-independent search for physics beyond the standard model in lepton final states. We examine 117 final states using 1.1  fb−1 of pp¯ collisions data at s√=1.96  TeV collected with the D0 detector. We ...
• #### Model of intracellular calcium concentration changes in bovine aortic endothelial cells ﻿

(1997)
The endothelium is a monolayer of cells which lines the inside of blood vessels. It responds to several different kinds of agonists by increasing the cytoplasmic concentration of calcium ions $(\lbrack Ca\sp{2+}\rbrack\sb{c}).$ ...
• #### MODEL OF SOLAR-WIND MAGNETOSPHERE COUPLING ﻿

(1987)
The control of the strength and pattern of magnetospheric convection by the interplanetary magnetic field (IMF) is well established. This control is widely interpreted as evidence for magnetic interconnection between the ...
• #### Model of superthermal ions in the dayside Venus ionosphere ﻿

(1993)
A model is presented which simulates the behavior of superthermal ions previously reported in the dayside ionosphere of Venus. The model considers effects of E $\times$ B and gradient drifts, charge exchange and collisions ...
• #### Model of superthermal ions in the postshock flow field at Venus ﻿

(1992)
The role of the superthermal ions in the dayside postshock ionospheric flow field at Venus is investigated in a 2-D model by integrating the equation of motion of a superthermal population of O$\sp+$ test particles and ...

(2007)
• #### Model of Venus ionopause formation ﻿

(1992)
A model is presented that simulates the physics of the Venus mantle plasma. A modified magnetohydrodynamic (MHD) fluid picture is assumed where the post-shock solar wind plasma is mass-loaded by photoionizations and other ...
• #### Model reduction of large spiking neurons ﻿

(2010)
This thesis introduces and applies model reduction techniques to problems associated with simulation of realistic single neurons. Neurons have complicated dendritic structures and spatially-distributed ionic kinetics that ...
• #### Model reduction of second order linear dynamical systems ﻿

(2005)
In this thesis, we propose several algorithms for model reduction of second order dynamical systems. These various projection methods are based on singular value decomposition, Krylov projection, and balanced truncation. ...
• #### Model reduction of strong-weak neurons ﻿

(2014)
We consider neurons with large dendritic trees that are weakly excitable in the sense that back propagating action potentials are severly attenuated as they travel from the small, strongly excitable, spike initiation zone. ...

(1973)
• #### Model validation and consistency ﻿

(2000)
This thesis addresses model validation, important in robust control system modeling, for the identification method developed by Antoulas. Given a system model, the problem is to assess whether the model is consistent with ...
• #### Model-Based Acquisition for Compressive Sensing & Imaging ﻿

(2013-09-16)
Compressive sensing (CS) is a novel imaging technology based on the inherent redundancy of natural scenes. The minimum number of required measurements which defines the maximum image compression rate is lower-bounded by ...
• #### Model-based clustering for multivariate time series of counts ﻿

(2010)
This dissertation develops a modeling framework for univariate and multivariate zero-inflated time series of counts and applies the models in a clustering scheme to identify groups of count series with similar behavior. ...
• #### Model-based clustering of large networks ﻿

(2013)
We describe a network clustering framework, based on finite mixture models, that can be applied to discrete-valued networks with hundreds of thousands of nodes and billions of edge variables. Relative to other recent ...
• #### Model-based Inverse Halftoning with Wavelet-Vaguelette Deconvolution ﻿

(2000-09-01)
In this paper, we demonstrate based on the linear model of Kite that inverse halftoning is equivalent to the well-studied problem of deconvolution in the presence of colored noise. We propose the use of the simple and ...
• #### Modeled and observed fine particulate matter reductions from state attainment demonstrations ﻿

(2014)
States rely upon photochemical models to predict the impacts of air quality attainment strategies, but the performance of those predictions is rarely evaluated retrospectively. State implementation plans (SIPs) developed ...
• #### Modeling 3D Minimal-Energy Curves of Given Length ﻿

(2005-01-04)
We present a subdivision scheme for the construction of 3D minimal-energy curves of given length that satisfy endpoint constraints. When given desired positions and tangents for the endpoints, and the length of the curve, ...
