In this paper, we examine the effect of solar flare event on the Global Positioning System (GPS) signal reception in Peninsular Malaysia during the X5.4 class solar flare on 7th March 2012, 00:24 UT a...
Relationship between geomagnetic classes’ activity phases and their occurrence during the sunspot cycle
Classes of geomagnetic activity Phases of geomagnetic classes Sunspot cycle
2015/8/28
Four well known geomagnetic classes of activity such as quiet days activity, fluctuating activity, recurrent activity and shock activity time occurrences have been determined not only by using time pr...
Record of Early Toarcian carbon cycle perturbations in a nearshore environment: the Bascharage section (easternmost Paris Basin)
Black shale deposit early Jurassic the negative carbon isotope
2015/1/6
In order to understand the significance of the worldwide deposition of black shale facies in the Early Toarcian (~ 183 Ma), considerable attention has been drawn to this Early Jurassic sub-stage over ...

Shift of effective lightning areas during pre to post period of solar cycle minimum of 2008-2009 as determined from Schumann resonance studies at Agra, India
Schumann resonance Thunderstorm activity Effective lightning areas
2015/8/18
Employing a set of 3-component search coil magnetometer, Schumann resonance studies have been in progress at Agra (Geograph. lat. 27.2°N, long. 78°E), India since 01 April, 2007. We have analysed the ...
Evidence for paleolakes in Erythraea Fossa, Mars: Implications for an ancient hydrological cycle
Mars Mars, Surface Mars, Climate Geological processes
2014/4/8
There is now widespread agreement that the surface of Mars underwent some degree of fluvial modification,but there is not yet full understanding of its surface hydrological cycle and the nature of sta...
Spectral‐element simulations of long‐term fault slip: Effect of low‐rigidity layers on earthquake‐cycle dynamics
Spectral‐element simulations of long‐term fault slip low‐rigidity layers earthquake‐cycle dynamics
2014/4/8
We develop a spectral element method for the simulation of long‐term histories of spontaneous seismic and aseismic slip on faults subjected to tectonic loading.
Our approach reproduces all stages of ...

Carbon-cycle global temperature the biosphere’s ability
2010/1/28
Researchers in Switzerland and Germany have analysed data stretching back over 1000 years to get the best estimate yet of how changes in global temperature affect the biosphere’s ability to soak up ca...
A simple model for the earthquake cycle combining self-organized complexity with critical point behavior
earthquake cycle self-organized complexity critical point behavior
2009/11/12
We have studied a hybrid model combining the forest-fire model with the site-percolation model in order to better understand the earthquake cycle. We consider a square array of sites. At each time ste...

hydrological cycle planetary climate system simple nonlinear dynamical model
2009/11/11
We present the construction of a dynamic area fraction model (DAFM), representing a new class of models for an earth-like planet. The model presented here has no spatial dimensions, but contains coupl...
