On the validity of the regional time and magnitude predictable model in China
time dependent seismicity validation test China
2015/9/30
A simplified form of the "regional time and magnitude predictable model" gives the time interval, T, between two successive mainshocks in a region and the magnitude, Mf, of the following mainshock by ...
Validity of the Hohenberg Theorem for a Generalized Bose-Einstein Condensation in Two Dimensions
Bose - Einstein condensation horn theorem states generalized condensation
2014/12/22
Several authors have considered the possibility of a generalized Bose-Einstein condensation (BEC) in which a band of low states is occupied so that the total occupation number is macroscopic, even if ...
Respiratory Inductance Plethysmography—A Rationale for Validity during Exercise
VENTILATION RUNNING EXERCISE MONITORING RESPIRATION AMBULATORY MONITORING
2017/5/18
The aim of this study was to provide a rationale for future validations of a priori calibrated respiratory inductance plethysmography (RIP) when used under exercise conditions. Therefore, the validity...
Validity of Viscous Core Correction Models for Self-Induced Velocity Calculations
Validity of Viscous Core Correction Models Self-Induced Velocity Calculations Computational Physics
2012/4/20
Viscous core correction models are used in free wake simulations to remove the infinite velocities at the vortex centreline. It will be shown that the assumption that these corrections converge to the...
Validity of the Refraction Microtremors (ReMi) Method for Determining Shear Wave Velocities for Different Soil Types in Egypt
Refraction Microtremors ReMi Crosshole Downhole Shear Wave Egypt
2013/3/7
The Refraction Microtremor (ReMi) method is being used around the world by the geotechnical and geophysical community to determine shear-wave velocities. This is due to its faster, less expensive and ...
Kramers' law: Validity, derivations and generalisations
Arrhenius’ law Kramers’ law metastability large deviations Wentzell Freidlin theory
2011/7/28
Abstract: Kramers' law describes the mean transition time of an overdamped Brownian particle between local minima in a potential landscape. We review different approaches that have been followed to ob...
A sufficient condition for the validity of quantum adiabatic theorem
A sufficient condition validity quantum adiabatic theorem
2010/10/29
In this paper, we attempt to give a sufficient condition of guaranteeing the validity of the proof of quantum adiabatic theorem. The new sufficient condition can clearly remove the inconsistency and c...
The validity of the kinetic collection equation revisited – Part 2: Simulations for the hydrodynamic kernel
the kinetic collection equation the hydrodynamic kernel
2010/8/16
The kinetic collection equation (KCE) has been widely used to describe the evolution of the average droplet spectrum due to the collection process that leads to the development of precipitation in war...
The Validity of Company Valuation Using Discounted Cash Flow Methods
Discounted Cash Flow valuation method
2010/4/27
This paper closely examines theoretical and practical aspects of the widely used discounted cash flows (DCF) valuation method. It assesses its potentials as well as several weaknesses. A special empha...
The Validity of the Super-Particle Approximation during Planetesimal Formation
planet formation planetesimals N-body simulations convergence accretion disc
2010/3/8
The formation mechanism of planetesimals in protoplanetary discs is hotly debated. Currently, the favoured model involves the accumulation of meter-sized objects within a turbulent disc, followed by a...
On the influence of temporal change on the validity of landslide susceptibility maps
temporal change validity landslide susceptibility maps
2009/12/8
The consideration of non-stationary landslide causal factors in statistical landslide susceptibility assessments is still problematic. The latter may lead to erroneous model predictions, especially in...
On the validity of ideal MHD in the vicinity of stagnation points in the heliosphere and other astrospheres
heliospheric boundaries magnetic fields stagnation points
2009/5/27
The paradigm of ideal MHD is investigated in the vicinity of null points of flows and magnetic fields. These null points determine the location and geometrical shape of the heliopause (or other astrop...
Some Doubts on the Validity of the Foreground Galactic Contribution
Cosmic microwave background—ISM clouds—dust extinction—ISM structure
2009/5/12
The Galactic foreground contamination inCMBRanisotropies,
especially from the dust component, is not easily separable from the cosmological
or extragalactic component. In this paper, some doubts wi...
The validity of the kinetic collection equation revisited
kinetic collection equation revisited
2008/10/30
The kinetic collection equation (KCE) describes the evolution of the average droplet spectrum due to successive events of collision and coalescence. Fluctuations and non-zero correlations present in t...
