ACCELERATION OF SEA LEVEL RISE OVER MALAYSIAN SEAS FROM SATELLITE ALTIMETER
Climate Change Sea Level Rise Satellite Altimeter
2016/10/14
Sea level rise becomes our concern nowadays as a result of variously contribution of climate change that cause by the anthropogenic effects. Global sea levels have been rising through the past century...
Monitoring Activity for Recognition of Illness in Experimentally Infected Weaned Piglets Using Received Signal Strength Indication ZigBee-based Wireless Acceleration Sensor
Acceleration Sensor Pig Activity Bacterial Infection Wireless Sensor Network
2016/5/20
In this experiment, we proposed and implemented a disease forecasting system using a received signal strength indication ZigBee-based wireless network with a 3-axis acceleration sensor to detect illne...

Fermi acceleration is a mechanism, first suggested by
Enrico Fermi in 1949, to explain heating of particles in cosmic
rays.
Peak ground acceleration produced by local earthquakes in volcanic areas of Campi Flegrei and Mt. Vesuvius
Peak ground acceleration Scaling law Stochastic method Mt. Vesuvius Campi Flegrei
2015/9/14
The scaling law of the seismic spectrum experimentally calculated at Mt. Vesuvius and Campi Flegrei is used to constrain the estimate of the maximum expected peak acceleration of ground motion.
Four decades of European geomagnetic secular variation and acceleration
European secular variation secular acceleration geomagnetic jerks
2015/8/28
Geomagnetic secular variation, the generally slow, continuous change in the core magnetic field, is characterized by occasional rapid variations known as geomagnetic jerks. Recent studies on magnetic ...
Anomalous secular sea-level acceleration in the Baltic Sea caused by isostatic adjustment

2015/8/18
Observations from the global array of tide gauges show that global sea-level has been rising at an average rate of 1.5-2 mm/yr during the last ~150 years [Douglas 1991, Spada and Galassi 2012]. Althou...
The stochastic acceleration problem in two dimensions
stochastic acceleration problem two dimensions
2015/7/14
We consider the motion of a particle in a two-dimensional spatially homogeneous mixing potential and show that its momentum converges to the Brownian motion on a circle. This complements the limit the...

Maximal acceleration Extended Relativistic Dynamics Hydrogen-like atom probabilistic description center of mass
2012/4/20
The existence of a maximal acceleration for massive objects was conjectured by Caianiello 30 years ago based on the Heisenberg uncertainty relations. Many consequences of this hypothesis have been stu...
