A 1D in position and 2D in velocity Particle in Cell with Monte Carlo Collision model of a low-pressure nitrogen discharge plasma has been coupled to a 1D reaction-diffusion kinetics for the whole vibrational ladder of the N2(X) state, for the vibrationally lumped N2(A), N2(B), N2(C), N2(a') states as well as for N atoms. The model includes several electron-molecule as well as molecule-molecule...

Seismic tomography models of the three-dimensional upper mantle velocity structure of the Mediterranean-Carpathian region provide a better understanding of the lithospheric processes governing its geodynamical evolution. Slab detachment, in particular lateral migration of this process along the plate boundary, is a key element in the lithospheric dynamics of the region during the last 20 to 30 ...

Traditional vehicle management system is based on metal plate mainly identified by the video and image processing techniques which are low accuracy and less efficiency. However based on RFID technology, electronic license has the unique factory curing ID number and the vehicle physical binding, making it incomparable anti-counterfeiting. Here the design scheme of the whole system including data...

As Earth evolved over the last 4.5 billion years, its mineralogy changed. As we peer back through Earth’s history, it seems logical to think that our lens would grow increasingly fogged and our light ever more dim. How do we see beyond the oldest preserved rocks and minerals, after billions of years of volcanism, plate tectonics, and weathering? How do we see past the Moon-forming collision, wh...

A Distributed-Lagrange-Multiplier(DLM)-based method is implemented for the simulation of particulate flow. Initially, we show that our fluid-particle solver produces results which are in good agreement with numerical studies of benchmark viscous flow problems. Subsequently, the bouncing motion of a solid sphere onto a solid plate in an ambient fluid is considered. Comparing results for the coef...

A new method for implementing collision welding at a laboratory scale has been developed. The pressure that drives the flyer plate toward the target is created by electrically driven rapid vaporization of a thin metallic conductor, rather than by chemical explosives or magnetic forces. Dissimilar welding couples of copper-titanium, copper-steel, aluminum-copper, aluminummagnesium and titanium-s...

We report on 2D collision experiments with 9 thin Delrin disks with variable axisymmetric mass distributions. The disks floated on an air table, and collided at speeds of about 0.5 to 1.0 m/s with a flat-walled stationary thick steel plate clamped to the table. The collision angle was varied. The observed normal restitution was roughly independent of angle, consistent with other studies. The fr...

Abstract Indonesia is located between three significant plate confluences that play a role in creating subduction zone. Sumatra, one of Indonesia’s provinces, near the collision Eurasian Plate, Indo-Australian and Pacific Plate. The Semangko Fault, Mentawai Islands, chain non-volcanic forearc islands, active faults induce earthquakes landslides are all produced by zones on Sumatra Island. recei...
