Data compression and definability of types in stable and dependent formulas
Data compression formulas
2015/9/28
Data compression and definability of types in stable and dependent formulas.
Compression schemes, stable definable families, and o-minimal structures
Compression schemes stable definable families o-minimal structures
2015/9/28
We show that any family of sets uniformly definable in an ominimal
structure has an extended compression scheme of size equal
to the number of parameters in the defining formula.
Some considerations for different time-domain signal processing of pulse compression radar
code correlation ionosphere radar time domain
2015/8/28
Radar technology has for a long time used various systems that allow detection under high-resolution conditions, while emitting at the same time low peak power. Among these systems, transmitted pulse ...
Compression of the electron repulsion integral tensor in tensor hypercontraction format with cubic scaling cost
electron repulsion integral tensor tensor hypercontraction format cubic scaling cost
2015/7/14
Electron repulsion integral tensor has ubiquitous applications in quantum chemistry calculations. In this work, we propose an algorithm which compresses the electron repulsion tensor into the tensor h...
Mechanical aspects of thrust faulting driven by far-field compression and their implications for fold geometry
Anticline Finite element Fold Frictional contact Rock Thrust fault
2015/7/1
In this paper we present a mechanical model that intends to captures the kinematical aspects of thrust fault related folds induced by regional-scale far-field contraction. Fold shapes may be the only ...
Acyclic edge-coloring using entropy compression
Acyclic edge-coloring entropy compression Combinatorics
2012/6/29
An edge-coloring of a graph G is acyclic if it is a proper edge-coloring of G and every cycle contains at least three colors. We prove that every graph with maximum degree Delta has an acyclic edge-co...
The MgSiO3 system at high pressure: Thermodynamic properties of perovskite, postperovskite, and melt from global inversion of shock and static compression data
perovskite postperovskite melt
2014/4/8
We present new equation-of-state (EoS) data acquired by shock loading to pressures
up to 245 GPa on both low-density samples (MgSiO3
glass) and high-density,
Partition Reduction for Lossy Data Compression Problem

2012/4/17
We consider the computational aspects of lossy data compression problem, where the compression error is determined by a cover of the data space. We propose an algorithm which reduces the number of par...
Lossless Linear Compression of Data with Minimal Dimension in Linear Minimum Variance Estimation
LMV estimation lossless compression linear transformation singular value
2011/11/11
Consider a Linear Minimum Variance (LMV) estimation problem where the linear transformation of data is needed to compress dimension of observation data without loss of performance. A necessary and su±...
