THEORETICAL MODELLING STUDY ON THE RELATIONSHIP BETWEEN MULTI-FREQUENCY MICROWAVE VEGETATION INDEX AND VEGETATION PROPERTIES (OPTICAL DEPTH AND SINGLE SCATTERING ALBEDO)
Microwave Vegetation Index Matrix Doubling Model Optical Depth Single Scattering Albedo Soil Moisture Roughness
2018/5/15
This paper presents a theoretical study of derivation Microwave Vegetation Indices (MVIs) in different pairs of frequencies using two methods. In the first method calculating MVI in different frequenc...
EFFECTS OF LIDAR DEM RESOLUTION IN FLOOD MODELLING: A MODEL SENTITIVITY STUDY FOR THE CITY OF TEGUCIGALPA, HONDURAS
Flood modelling DEM resolution LIDAR SOBEK
2015/8/13
An important aspect of hydraulic flood modelling deals with representing topography of river and floodplain. Commonly, flood
model applications are reported successful in topographically simple area...
Computationally efficient methods for modelling laser wakefield acceleration in the blowout regime
Computationally efficient methods modelling laser wakefield acceleration blowout regime Accelerator Physics
2012/4/19
Electron self-injection and acceleration until dephasing in the blowout regime is studied for a set of initial conditions typical of recent experiments with 100 terawatt-class lasers. Two different ap...

Energy harvesting (EH) is a multidisciplinary research area, involving physics, materials science and engineering, with the objective of providing renewable sources of sufficient power to operate targ...
Modelling the helical-flexo-electro-optic effect
helical-flexo-electro-optic effect flexoelectric coupling electric fields
2011/8/18
Abstract: The helical-flexo-electro-optic effect shows interesting in-plane electro-optic switching behaviour due to flexoelectric coupling with applied electric fields. Previous understanding of the ...
Modelling Complexity: the case of Climate Science
Uncertainty, Probability, Climate Models, Climate Change, Climate Variability, Spatial scales, Time scales, Chaos, Numerical Methods, Irreversibility, Entropy Production, Energy Balance
2011/8/30
We briefly review some of the scientific challenges and epistemological issues related to climate science. We discuss the formulation and testing of theories and numerical models, which, given the pre...

2010/4/27
Labor productivity in Turkey, Spain, Belgium, Austria, Switzerland, and New Zealand has been analyzed and modeled. These counties extend the previously analyzed set of the US, UK, Japan, France, Italy...
Modelling Extreme-Mass-Ratio Inspirals using Pseudospectral Methods
Gravitational Waves Astronomy Extreme-Mass-Ratio Inspirals Self-Force
2010/3/18
We introduce a new time-domain method for computing the self-force acting on a scalar particle in a Schwarzschild geometry. The principal feature of our method consists in the division of the spatial ...
Multi-channel modelling of the formation of vibrationally cold polar KRb molecules
Multi-channel modelling vibrationally cold polar KRb molecules
2010/4/8
We describe the theoretical advances that influenced the experimental creation of vibrationally and translationally cold polar $^{40}$K$^{87}$Rb molecules \cite{nphys08,science08}. Cold molecules were...
Modelling longwave radiation to snow beneath forest canopies using hemispherical photography or linear regression
forest snow canopy radiation modelling longwave radiation hemispherical photography
2014/4/3
Forest canopies reduce shortwave radiation and increase longwave radiation reaching the underlying surface, compared with
open areas, and thus influence rates at which forest snowpacks melt. Th...
In this paper we seek the solutions of the time dependent
Ginzburg-Landau model for type-II superconductors such that the
associated physical observables are spatially periodic with respect to
some...
