The fundamental parameters of astrophysical plasma turbulence and its dissipation: non-relativistic limit

Journal of Plasma Physics
A specific set of dimensionless plasma and turbulence parameters is introduced to characterize the nature of turbulence and its dissipation in weakly collisional space and astrophysical plasmas.

Effect of different vegetation restoration types on fundamental parameters, structural characteristics and the soil quality index of artificial soil

Soil & Tillage Research, 2018
Outside soil spray seeding (OSSS), the technology of spraying an artificial soil mixture onto the surface of cut slopes for creating a bed for plant species to germinate and grow, has been widely used to restore cut slopes.

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 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

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 CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics

Physics of the Dark Universe
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades. This concordance model is constructed by a universal cosmological constant

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 ...
