Adaptive Distributed Source Coding Based on Bayesian Inference
Chen, Feng (2015-08-14)Distributed Source Coding (DSC) is an important topic for both in information theory and communication. DSC utilizes the correlations among the sources to compress data, and it has the advantages of being simple and easy ... -
Assessing Dual-Doppler Vertical Velocity Retrievals from Rapid-Scan Radar Data
Gebauer, Joshua (2020-12)Vertical velocity is the most difficult wind component to accurately retrieve from dual- Doppler observations. Typical radar scans are conducted with shallow elevation angles and therefore, the radial velocity observations ... -
Assimilation of ground-based remote sensors for improving the prediction of bore-generating nocturnal convection
Chipilski, Hristo Georgiev (2021-08)Advances in Numerical Weather Prediction (NWP) require a synchronous improvement in the structure of the underlying Global Observing System (GOS). However, recent progress toward high-resolution modeling has not been ... -
Breaking the Practical Performance Barriers of Polarimetric Phased Array Weather Radars
Salazar Aquino, Cesar (2022-12-16)Phased array radars (PAR) are being proposed as an alternative to replacing the Next Generation Weather Radar (NEXRAD) network, which has been in service for more than 30 years, reaching the end of its life cycle. The PAR ... -
Controllability of Linear and Nonlinear Control Systems related through Simulation Relations
Ho, Nancy (2015-12)For nonlinear input-disturbance systems that are connected by a simulation relation, we examine to what extent they share certain controllability properties. Specifically our main objective is to determine the conditions ... -
Convergence Rates for Stationary Distributions of Semistochastic Processes
Broda II, James (2017-05)The primary objects of study in this dissertation are semistochastic processes. The types of semistochastic processes we consider are continuous-time and continuous-state processes consisting of intervals of deterministic ... -
Development and Application of a Unified Framework for Meso to Synoptic Scale Error Growth Diagnosis and Weather Extremes in Global Numerical Weather Prediction
Lillo, Samuel (2021-12)While the average skill of medium-range numerical weather prediction (NWP) has steadily improved over the last three decades, there is still considerable variance in day-to-day forecast performance. Much of this variance ... -
Finite difference method on 1D and 2D Riemann problems for Euler equations with different state of equations
Jin, Ling (2022-08-04)We discussed the finite difference WENO5 scheme on the 1D and 2D compressible Euler equations. The 1D Chaplygin gas system with a constant external force led to two kinds of solutions: contact discontinuity and delta shock. ... -
GEOMETRIC QUANTIZATION OF A SEMI-GLOBAL MODEL OF A FOCUS-FOCUS SINGULARITY
Sunkula, Mahesh (2019-08-01)Quantization of a classical mechanical system is an old problem in physics. In classical mechanics, the evolution of the system is given by a Hamiltonian vector field on a symplectic manifold (``phase space''). ... -
A Kinematic and Thermodynamic Analysis of the 17 May 2019 McCook / Farnam, Nebraska Tornadic Supercell
Satrio, Martin (2023-08-04)The Targeted Observation by Radars and UAS of Supercells field project successfully deployed on a cyclic tornadic supercell in southwest Nebraska on 17–18 May 2019. This case study uses data from the two airborne radars ... -
LOCAL ESCAPE RATE DICHOTOMY FROM A PROBABILITY POINT OF VIEW
Davis, Connor (2020-07-30)We will discuss a dichotomy pertaining to escape rates in dynamical systems. This dichotomy pertains to the limiting behavior of the escape rate as it is compared to the size of a shrinking hole (the local escape rate). ... -
Measuring The Trilinear Higgs Couplings at LHC
Wickramarachchi, Priyangika (2015-12)The results from the Large Hadron Collider (LHC) indicate that the couplings of the Higgs boson to other particles are consistent with the Standard Model. The coupling of the Higgs boson to itself will be the final and ... -
MODELING AND CONTROL OF MICROGRID COMPONENTS
Tajik, Elham (2018-12-14)Due to the increase in the integration of renewable energy resources into electrical power systems, there are various challenges that modern power systems are facing. A lot of issues in this subject are discussed under ... -
A Multiscale Investigation of the 26–27 April 2011 Tornado Outbreak
Chasteen, Manda (2021-12)One of the most prolific tornado outbreaks ever documented occurred on 26–27 April 2011 and comprised three successive episodes of tornadic convection that primarily impacted the southeastern United States, including two ... -
Naturalness in Supersymmetry
Padeffke-Kirkland, Maren (2015-06)Weak scale supersymmetry solves the Big Hierarchy problem of the Standard Model. But recent severe sparticle mass limits from the LHC accentuate the Little Hierarchy Problem: Why are the W , Z and h masses so small (∼ 100 ... -
NORM RETRIEVAL FROM SPATIOTEMPORAL SAMPLES
Bozkurt, Fatma (2018-12)The goal of this dissertation is to investigate norm retrievable frames having dynamical sampling structure, particularly those that fail the phase retrieval con- dition. We give several classifications to show how to ... -
ON THE EXISTENCE OF KAM TORI FOR PRESYMPLECTIC VECTOR FIELDS
Bauer, Sean (2016-05)We prove the existence of a torus that is invariant with respect to the flow of a presymplectic vector field found in a family of presymplectic vector fields. Moreover, the flow on this invariant torus is conjugate to a ... -
Oscillation theory for canonical systems, applications, and a couple of other things
Scarbrough, Kyle (2020-07-30)Oscillation theory for canonical systems is developed. This is then applied to various topics related to semibounded systems and the essential spectrum. The correspondence between self-adjoint relations and self-adjoint ... -
PERIODIC SOLUTIONS OF THE DISPERSION-MANAGED NONLINEAR SCHRODINGER EQUATION
Adekoya, Oreoluwa (2019-05-10)We study the existence, uniqueness and stability of solutions to the initial-value problem for the periodic dispersion-managed nonlinear Schr\"{o}dinger (DMNLS) equation, an equation that models the propagation of periodic, ... -
