Secure parameter estimation: Fundamental tradeoffs

2017 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2017
The problem of parameter estimation in an adversarial setting, in which an active adversary might decide to compromise the data for the purpose of subverting the estimation decisions, is considered. Forming secure estimation decisions entails two intertwined inference decisions.

Fundamental image quality parameters of poroelastography

2011 IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2011
Poroelastography is an emerging elastographic technique that aims at imaging the temporal mechanical behavior of fluid-filled tissues. While standard elastographic methods focus primarily on the visualization of soft and hard tissue regions as being indicative of tissue pathological changes, poroelastography allows imaging several novel parameters that

Fundamental parameters of BE UMa revised

Astronomy Reports, 2008
We have determined a complete set of parameters for the young pre-cataclysmic variable BE UMa from a comprehensive photometric and spectroscopic analysis using model atmospheres. Our precise photometry and spectroscopy were acquired with the 6-m telescope and Zeiss-1000 telescope of the Special Astrophysical Observatory and the 1.5-m Russian-Turkish ...

The Fundamental Parameters of Cosmology

Publications of the Astronomical Society of the Pacific, 1999
I describe the evidence for the big bang, including the various cosmological parameters. There is general concordance on their values, although the uncertainties remain large enough to justify the ensuing debate. Structure formation is reviewed, and here there is consensus on the hierarchical nature of the sequence of formation.

The Fundamental Parameters of Massive Stars

AIP Conference Proceedings, 2009
We analyzed far‐UV (FUSE), UV (HST, IUE) and optical spectra of hot massive stars in the Milky Way with non‐LTE, line‐blanketed models with sphericity and expanding winds. We were able to reconcile previously discrepant diagnostics from Hα to highly ionized transitions (e.g.

Fundamental Parameters of Antennas

2009
The most basic properties of an antenna are its radiation pattern, gain, impedance, and polarization. These properties are identical for linear passive antennas used either as a transmitter or receiver by virtue of the reciprocity theorem [1]. A complete definition of the terms used for antennas can be found in [2]. The radiation pattern is defined in

Fundamentals of Robust Parameter Estimation

2017
The research of parameter estimation in different models of real systems resulted in the development of a number of algorithms possessing theoretically optimal properties regarding a chosen criterion.

Fundamental Parameters of B Supergiants

2006
To understand the chemical evolution of galaxies, we need a deep understanding of the evolution of massive stars and their role in processing and delivering chemical elements. B-type supergiants represent a substantial population in this context. We present here initial results from non-LTE, line-blanketed stellar atmosphere modelling [1] of a large ...

The nature of topological parameters. I. Are topological parameters `fundamental properties'?

Journal of Computer-Aided Molecular Design, 2003
Topological parameters are often used descriptors in QSAR and QSPR studies. Though easily generated from an appropriate algorithm useful in developing predictive models they are not readily interpretable. Though every molecule has an intrinsic topology it is not clear whether topological parameters are 'fundamental' properties or not.
