A possible model for initiationof ULF oscillation in magma
ULF oscillations magma volcano electromagnetic emission
2015/9/14
During the period just prior to an earthquake, an electomagnetic emission develops over seismic zones. In this paper, a model of excitation of magnetic fields over zones of volcanic activity is propos...
Analysis of Laser Power Threshold for Self Oscillation in Thermo-Optically Excited Doubly Supported MEMS Beams
MEMS Limit cycle Hopf bifurcation Numerical continuation Resonator
2015/8/26
An optically thin MEMS beam suspended above a substrate and illuminated with a CW laser forms an interferometer, coupling out-of-plane deflection of the beam to absorption within it. In turn, laser ab...
Fisheries,El Niño-Southern Oscillation and Upper Ocean Temperature Records:An Eastern Pacific Example
Fisheries El Nino-Southern Oscillation Upper Ocean Temperature Records Eastern Pacific Example
2015/8/19
It is often recounted that the collapse of the Peruvian anchoveta fishery in the early 1970s was a direct consequence of the El Niño of 1972–73. Comparison of time series of upper-ocean thermal d...
TOGA-TAO and the 1991–93 El Nino Southern Oscillation Event
TOGA-TAO Nino Southern Oscillation Event
2015/8/19
The El Niño-Southern Oscillation (ENSO) phenomenon is an interannual perturbation of the climate system characterized by aperiodic weakening of the tradewinds and warming of the surface layers in...

Oscillation of the Measurement Accuracy of the Center Location of an Ellipse on a Digital Image
Experiment Accuracy Measurement Digital Image Target
2014/9/9
Circular targets are often utilized in photogrammetry and a circle on a plane is projected as an ellipse onto an oblique image. This paper reports an experiment conducted to investigate whether the me...
Update of the Chronology of Natural Signals in the Near-Surface Mean Global Temperature Record and the Southern Oscillation Index
Climate Variability Southern Oscillation Index ENSO
2013/3/11
Time series for the Southern Oscillation Index and mean global near surface temperature anomalies are compared for the 1950 to 2012 period using recently released HadCRU4 data. The method avoids a foc...
