Experimental investigation on steady granular flows interacting with an obstacle down an inclined channel: study of the dead zone upstream from the obstacle. Application to interaction between dense snow avalanches and defence structures
Experimental investigation steady granular flows the dead zone upstream dense snow avalanches defence structures
2009/12/9
An experimental investigation with dry granular flows passing over an obstacle down a rough inclined channel has been performed. The aim is to improve our understanding of the interaction between dens...
Investigation of over-horizon VHF radio signals associated with earthquakes
over-horizon VHF radio signals earthquakes
2009/12/9
This paper presents the preliminary results on the possible reception of over-horizon VHF radio signals from a FM (frequency modulation) transmitter during abnormal situations (probably in close assoc...
Investigation of long period crustal deformation on the inactive branch of the North Anatolian Fault Zone
long period crustal deformation inactive branch North Anatolian Fault Zone
2009/12/8
The western part of North Anatolian Fault (NAF) bifurcates around Mudurnu into two fault segments: northern and southern branch. The latter bifurcates again at west of Pamukova and creates middle stra...
Investigation of recent catastrophic landslides in the flysch belt of Outer Western Carpathians (Czech Republic):progress towards better hazard assessment
catastrophic landslides flysch belt Outer Western Carpathians hazard assessment
2009/12/8
Rapid snow melting and intense precipitation triggered and reactivated tens of mostly shallow landslides in the eastern part of the Czech Republic at the turn of March and April 2006. This area is bui...
Investigation of a parameter estimation method for contaminant transport in aquifers
Investigation parameter estimation method contaminant transport aquifers
2009/12/4
Real world groundwater aquifers are heterogeneous and system variables are not uniformly distributed across the aquifer. Therefore, in the modelling of the contaminant transport, we need to consider t...
Investigation of Relationship between Economy and Environment

2009/12/3
The economic activity is based on the necessary of human development. The environment changes when thesociety develops. The relationship between society and environment is always an important topic wh...
Investigation of the anomaly in η-photoproduction off the neutron
photoproduction eta-meson narrow nucleon resonance
2009/11/24
Quasi-free photoproduction of η-mesons off the neutron and off the proton has been studied using a deuterium target and bremsstrahlung photons produced by MAMI-C with incident energies up to 1.5 GeV...
Analytical and numerical investigation of nonlinear internal gravity waves
Analytical and numerical investigation nonlinear internal gravity waves
2009/11/12
The propagation of long, weakly nonlinear internal waves in a stratified gas is studied. Hydrodynamic equations for an ideal fluid with the perfect gas law describe the atmospheric gas behaviour. If w...
An investigation of nucleation events in a coastal urban environment in the Southern Hemisphere
nucleation events coastal urban environment Southern Hemisphere
2009/11/9
Ambient aerosols play an important role in atmospheric processes affecting the human and natural environments. They affect air quality, reduce visibility, and induce climate change by directly scatter...
A global mathematical investigation of a predator-prey model
predator-prey plane differential system
2010/4/8
We construct a global bifurcation diagram of the plane differential system $$ {l} \dot x = x(1-x)-x y/(a+x^2), \dot y = y(\delta-\beta y/x), x(t)>0, y(t)>0, a>0, \delta>0, \beta>0, $$ which describes ...
ENSO dynamics in current climate models:an investigation using nonlinear dimensionality reduction
ENSO dynamics current climate models nonlinear dimensionality reduction
2009/10/30
Linear dimensionality reduction techniques, notably principal component analysis, are widely used in climate data analysis as a means to aid in the interpretation of datasets of high dimensionality. T...
GROUND WATER INVESTIGATION IN GNEISSIAN ROCK,SYSTEMATIC STUDY OF A SMALL AREA
GROUND WATER INVESTIGATION GNEISSIAN ROCK SYSTEMATIC STUDY
2009/10/29
Careful investigations should precede drillings in hard rocks for drinking
water. A description is given of a method for groundwater prospecting in
hard rocks which integrates studies of petrography...

Decade's Investigation Stability Erodible Stream Beds
2009/10/29
This paper reviews work on the stability of a particulate stream bed to the erosive
attack of a flow with a free surface. Attention is given to the development of the
hydraulic, the potential-flow a...
