Cold, dense quark matter
… quantum chromodynamics (QCD) in the context of dense neutron star cores. We discuss the physical motivation for studying quark matter, and how the fundamental symmetry and symmetry breaking patterns of QCD guide the construction of phenomenological quark models – in particular, the …

Relaxation of Dense Suspension
Dense suspensions exhibit complex rheological behavior by behaving liquid-like at low shear stresses and solid-like at high shear stresses. The microscopic interactions between individual particles create non-Newtonian macroscopic behaviors by transitioning from hydrodynamic interactions to …

Survival guide for dense networks
… to cope with the high contention expected in dense networks. While increased delay and reduced throughput are predictable results of contention from background traffic, high contention increases collisions, resulting in increased packet retransmissions and dropped packets. Two factors are …

Nuclear physics and dense matter
Crucial to understanding the properties of dense matter in supernova explosions and neutron stars is determining the role of the nuclei present in such matter. Because many of the properties of the matter do not depend strongly on the fine details of nuclear structure, the liquid drop model of the …

Relaxation behavior of dense suspensions
Dense suspensions of solid particles in Newtonian fluids exhibit a variety of non-Newtonian behaviors depending on the shear stress applied to the suspension and the particle mass fraction ([mathematical symbol]m). Suspensions at sufficiently high fm shear-thicken dramatically and eventually shear …

Transonic aerodynamics of dense gases
Transonic flow of dense gases for two-dimensional, steady state, flow over a NACA 0012 airfoil was predicted analytically. The computer code used to model the dense gas behavior was a modified version of Jameson's FLOS2 airfoil code. The modifications to the code enabled modeling the dense gas …

Classification of Dense Masses in Mammograms
… in the Classification of tumors, non-tumors, and dense masses in a Mammogram, certain characteristics such as texture in a mammographic image are used to identify the regions of interest as a part of classification. Pattern recognizing techniques such as nearest mean classifier and Support vector …

Electronic structure of warm dense matter
The electronic structure of warm dense matter has been investigated using absorption spectroscopy by looking at shifts in the K-edge position of shocked compressed parylene-C and potassium chloride. The Vulcan laser facility was used to drive double sided shocks into the embedded chlorine samples …

XUV probing of warm dense matter
… to test models of free-free absorption in warm dense aluminium by Iglesias, Shaffer et al. and Hollebon et al., Radiative heating using L-shell x-rays from a high temperature palladium plasma was used to heat an aluminium foil to a temperature of 0.9±0.23eV. Before the sample could significantly …

Variational Theory of Hot Dense Matter
… can be used for practical calculations of hot dense matter. Our calculations are a significant improvement over the previous calculation due to Friedman and Pandharipande. The Hamiltonian contains modern realistic two nucleon and three nucleon interactions along with relativistic boost …

Dense matter in effective meson theories
In the limit of a large number of colors, quantum chromodynamics is thought to reduce to a theory in which mesons are the relevant degrees of freedom. Baryons emerge as topological solitons in such theories. Nucleon properties are well reproduced within these models--the agreement with experiment …

The Chromatic Structure of Dense Graphs
… the sparse problem degenerates away from the dense one. Finally, Chapter 7 considers a chromatic Ramsey problem first posed by Erdős: what is the greatest chromatic number of a triangle-free graph on $n$ vertices or with m edges? We improve the best known bounds and obtain tight (up to a …

Discount bundling via dense product embeddings
… sets created from click-stream data to generate dense continuous representations of products called embeddings. We then put minimal structure on these embeddings and develop heuristics for complementarity and substitutability among products. Subsequently, we use the heuristics to create multiple …

Dense visual learning for robot manipulation
… with the scalable ability to understand the dense visual state of their varied environments. The limitations have both been in the state representations used, and how to acquire them without significant human labeling effort. In this thesis we present work that leverages self-supervision, …

Continual Learning for Deep Dense Prediction
… alleviate catastrophic forgetting for pixel-wise dense labeling problems. We build upon the regularization technique using knowledge distillation to minimize the discrepancy between the posterior distribution of pixel class labels for old tasks predicted from 1) the original and 2) the updated …

Viscous-inviscid interactions of dense gases
The interaction of oblique shocks and oblique compression waves with a laminar boundary layer on an adiabatic flat plate is analyzed by solving the Navier-Stokes equations in conservation-law form numerically. The numerical scheme is based on the Beam and Warming’s implicit method with approximate …
