Deriving numerical estimates from descriptive information: the computation of earthquake parameters
macroseismic epicenter epicentral intensity macroseismic magnitude
2015/9/30
We describe here how the origin time, the epicenter location, the epicentral intensity and the magnitude of the earthquakes included in the Catalogue of Strong Italian Earthquakes (CFTI3) have been de...
SimSphere model sensitivity analysis towards establishing its use for deriving key parameters characterising land surface interactions
SimSphere model sensitivity establishing
2014/12/19
Being able to accurately estimate parameters characterising land surface interactions is currently a key scientific priority due to their central role in the Earth’s global
energy and water cyc...
Deriving the radial-velocity variations induced by stellar activity from high-precision photometry - Test on HD189733 with simultaneous MOST/SOPHIE data
late-type – stars: activity – stars: rotation – techniques: radial velocity – planetary systems – stars: individual
2011/10/19
Stellar activity induces apparent radial velocity (RV) variations in late-type main-sequence stars that may hamper the detection of low-mass planets and the measurement of their mass. We use simultane...
Deriving the existence of $B\bar{B}^*$ bound states from the X(3872) and Heavy Quark Symmetry
Deriving the existence Heavy Quark Symmetry
2011/7/21
We discuss the possibility and the description of bound states between $B$ and $\bar{B}^*$ mesons. We argue that the existence of such a bound state can be deduced from (i) the weakly bound X(3872) st...
Generating functions for the Bernstein polynomials: A unified approach to deriving identities for the Bernstein basis functions
Bernstein polynomials generating function Szasz-Mirakjan basis functions
2011/2/28
The main aim of this paper is to provide a unified approach to deriving identities for the Bernstein polynomials using a novel generating function. We derive various functional equations and different...
Sphere packing problems have a rich history in both mathematics and physics; yet,
relatively few analytical analyses of sphere packings exist, and answers to seemingly simple ques-tions are unknown. ...
A general framework for deriving integral preserving numerical methods for PDEs
general framework deriving integral preserving numerical methods PDEs
2010/12/8
A general procedure for constructing conservative numerical integra-tors for time dependent partial di erential equations is presented. In particular, linearly implicit methods preserving a time avera...
Deriving Bell's nonlocality from nonlocality at detection
Deriving Bell nonlocality nonlocality detection
2010/10/18
It is argued that Bell’s nonlocality is a particular case of nonlocality at detection, which appears already in single-particle interference experiments. The unity of nonlocality and local causality i...
A new method for deriving aerosol solar radiative forcing and its first application within MILAGRO/INTEX-B
aerosol solar radiative forcing first application MILAGRO/INTEX-B
2010/8/25
We introduce a method for deriving aerosol spectral radiative forcing along with single scattering albedo, asymmetry parameter, and surface albedo from airborne vertical profile measurements of shortw...
Uncertainty analysis of computational methods for deriving sensible heat flux values from scintillometer measurements
Uncertainty analysis computational methods sensible heat flux values scintillometer measurements
2010/2/8
The use of scintillometers to determine sensible heat fluxes is now common in studies of land-atmosphere interactions. The main interest in these instruments is due to their ability to quantify energy...
A Comparison of Some Methods of Deriving the Instantaneous Unit Hydrograph
Comparison Some Methods Instantaneous Unit Hydrograph
2009/10/28
The geomorphological instantaneous unit hydrograph (IUH) proposed by
Gupta et al. (1980) was compared with the IUH derived by commonly used
time-area and Nash methods. This comparison was performed ...
DERIVING LAND COVER OF A LARGE AGRICULTURAL WATERSHED FROM MULTI-TEMPORAL LANDSAT SCENES
Agricultural NonPoint Source Pollution large watersheds Thematic Mapper hydrologic models
2009/10/13
Determining land-cover characteristics of large watersheds for use in hydrologic models has been enhanced by application of remotely sensed data and the technologies used to interpret them. The object...
Deriving inherent optical properties and associated inversion-uncertainties in the Dutch Lakes
chlorophyll-a suspended particulate matters inherent optical properties
2009/7/22
Remote sensing of water quality in inland waters requires reliable retrieval algorithms, accurate atmospheric correction and consistent method for uncertainty estimation. In this paper, the GSM semi-a...
Dynamical process upscaling for deriving catchment scale state variables and constitutive relations for meso-scale process models
catchment scale state variables meso-scale process models
2009/5/15
In this study we propose an uspcaling approach to derive time series of (a) REW scale state variables, and (b) effective REW scale soil hydraulic functions to test and parameterise models based on th...
Deriving albedo maps for HAPEX-Sahel from ASAS data using kernel-driven BRDF models
