A Neural Network based Background Supression Technique applied to VHE Gamma Ray Data coming from the Crab Pulsar
Imaging Atmospheric Cherenkov Technique Flux Upper Limit
2014/12/12
In this thesis we present new results for the 99.9% confidence level flux upper limits on the pulsed VHE gamma ray signal coming from the Crab pulsar. In order to achieve optimum hadronic background s...
Kernel based unfolding of data obtained from detectors with finite resolution and limited acceptance
unfolding kernel apparatusfunction inverseproblem regularization
2012/11/23
A kernel based procedure for correcting experimental data for distortions due to the finite resolution and limited detector acceptance is presented. The unfolding problem is known to be an ill-posed p...
A method for filling gaps in solar irradiance and in solar proxy data
filling gaps solar irradiance solar proxy data
2011/8/17
Abstract: Data gaps are ubiquitous in spectral irradiance data, and yet, little effort has been put into finding robust methods for filling them. We introduce a data-adaptive and nonparametric method ...
Inverse Ising inference using all the data
Inverse Ising inference data logistic regression
2011/8/17
Abstract: We show that a method based on logistic regression, using all the data, solves the inverse Ising problem far better than mean-field calculations relying only on sample pairwise correlation f...
Reconstructing signals from noisy data with unknown signal and noise covariance
statistics information theory statistical mechanics
2011/8/17
Abstract: We derive a method to reconstruct Gaussian signals from linear measurements with Gaussian noise. This new algorithm is intended for applications in astrophysics and other sciences. The start...
Comparison of SCIPUFF Plume Prediction with Particle Filter Assimilated Prediction for Dipole Pride 26 Data
Data Assimilation Particle Filter Chem-BioField Test Dispersion Model
2011/8/16
Abstract: This paper presents the application of a particle filter for data assimilation in the context of puff-based dispersion models. Particle filters provide estimates of the higher moments, and a...
Non-commutative tomography: A tool for data analysis and signal processing
Non-commutative tomography data analysis signal processing
2011/8/2
Abstract: Tomograms, a generalization of the Radon transform to arbitrary pairs of non-commuting operators, are positive bilinear transforms with a rigorous probabilistic interpretation which provide ...
Nonparametric model reconstruction for stochastic differential equation from discretely observed time-series data
Nonparametric model reconstruction stochastic differential equation discretely observed time-series data
2011/8/2
Abstract: We develop a scheme for estimating state-dependent drift and diffusion coefficients in a stochastic differential equation from a time-series data. There is no need to have any prior knowledg...
Evaluating Data Assimilation Algorithms
Evaluate Data Assimilation Algorithms assimilation refers
2011/8/5
Abstract: Data assimilation refers to methodologies for the incorporation of noisy observations of a physical system into an underlying model in order to infer the properties of the state of the syste...
Asymptotic simplicity and static data
General Relativity asymptotic structure spatial infinity
2010/12/20
The present article considers time symmetric initial data sets for the vacuum Einstein field equations which in a neighbourhood of infinity have the same massless part as that of some static initial d...
Staggered chiral perturbation theory in the two-flavor case and SU(2) analysis of the MILC data
Staggered chiral perturbation theory two-flavor case SU(2) analysis of the MILC data
2011/1/13
In the light pseudoscalar sector, we study rooted staggered chiral perturbation theory in the
two-flavor case. The pion mass and decay constant are calculated through NLO for a partiallyquenched theo...
A statistical-mechanical view on source coding: physical compression and data compression
statistical-mechanical physical compression data compression
2010/11/23
We draw a certain analogy between the classical information–theoretic problem of lossy data compression (source coding) of memoryless information sources and the statistical mechanical behavior of a c...
A critical look at V_us determinations from hadronic tau decay data
critical look V_us determinations hadronic tau decay data
2011/1/6
A critical review of hadronic decay data based determinations of |Vus| is given, focussing on the impact of the slow convergence of the integrated D = 2 OPE series for the conventional flavor-breaki...
Validation and Verification of MCNP6 Against Intermediate and High-Energy Experimental Data and Results by Other Codes

2011/1/7
MCNP6, the latest and most advanced LANL transport code representing a recent merger of MCNP5 and MCNPX, has been Validated and Verified (V&V) against a variety of intermediate and high-energy experim...
Imbalanced data sets containing much more background than signal instances are very common
in particle physics, and will also be characteristic for the upcoming analyses of LHC data. Following up the...
