Secure parameter estimation: Fundamental tradeoffs
2017 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2017The 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 Parameters of Antennas
2009The 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

Fundamental Parameters of B Supergiants
2006To 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 ...

Fundamental parameters of BE UMa revised
Astronomy Reports, 2008We 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, 1999I 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, 2009We 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.
