Functional quantization
… we care about. Traditional data compression and quantization techniques, designed to recreate or approximate the data itself, gloss over this point. Are performance gains possible if source coding accounts for the user's function? How about when the encoders cannot themselves compute the …

Effective loop quantization of black holes : a comparative analysis of quantization schemes.
Loop quantization of spherically symmetric black hole (BH) spacetimes has quantization ambiguities stemming from the choices (schemes) of the two polymerization parameters that characterize quantum corrections in effective loop quantum gravity (LQG). In this dissertation we systematically carry out …

Quantization Dimension for Probability Definitions
The term quantization refers to the process of estimating a given probability by a discrete probability supported on a finite set. The quantization dimension Dr of a probability is related to the asymptotic rate at which the expected distance (raised to the rth power) to the support of the …

Acoustic mode quantization in nanostructures
Brillouin light scattering has been employed to investigate the confined acoustic modes of three different nanostructures, viz. silica and polystyrene nanospheres, hollow carbon microspheres, and GeO2 nanocubes. The confined acoustic modes observed show significantly different features from those …

Quantization of anomalous gauge theories
"We discuss the quantization of Anomalous Gauge Theories (AGT) both in the context of functional integration and canonical Hamiltonian approach. The Wess-Zumino term (WZT), which repairs gauge symmetry in AGT is discussed and its derivation is presented in the canonical approach as a consequence of …

Functional quantization-based stratified sampling
Functional quantization-based stratified sampling is a method for variance reduction proposed by Corlay and Pagès (2015). This method requires the ability to both create functional quantizers and to sample Brownian paths from the strata defined by the quantizers. We show that product quantizers are …

Nonattribution Properties of JPEG Quantization Tables
… using only the header information, such as quantization table and huffman table, of the JPEG encoding. Having done research on around 110, 000 images, we reached to state that "For all practical purposes, using quantization and huffman tables alone to predict a camera make and model isn't a …

Casimir-Polder interaction in second quantization
The Casimir-Polder interaction between a single neutral atom and a nearby surface, arising from the (quantum and thermal) fluctuations of the electromagnetic field, is a cornerstone of cavity quantum electrodynamics (cQED), and theoretically well established. Recently, Bose-Einstein condensates …

Quantization Points of Densities and Samples
… by a finite number of values is known as quantization. Given a probability density function (p.d.f.) or a random sample, the quantization problem is to choose those k values (or points) that will best represent the given p.d.f. or sample. The optimal quanitization points (also known as …

Quantization of Fields of Arbitrary Spin
The search for relativistic field equations for elementary particles of arbitrary spin is a long standing problem of Quantum Field Theory. Although much work has been done on relativistic field theories describing fields with various mass-spin spectra, little has been done on picking out those …

Sampling and quantization for optimal reconstruction
… The thesis first considers the effects of quantization in the environment of interleaved, oversampled multi-channel measurements with the potential of different quantization step size in each channel and varied timing offsets between channels. Considering sampling together with quantization …

Quantization and erasures in frame representations
… coefficients, with specific focus on quantization and erasure errors. The projections are implemented by modifying the unaffected coefficients using an additive term, which is linear in the error. This low-complexity implementation only assumes linear reconstruction using a …
