There is a lack of scientific knowledge about the physical sea characteristics eastern part Mediterranean Sea. The current work offers comprehensive view wave fields in southern Israel waters covering period between January 2017 and June 2018. analyzed data were collected by meteorological buoy providing wind parameters. As expected for this area, strongest storm events occurred throughout Octo...

pulsed current plasma arc welding (pcpaw) is one of the most widely used welding processes in sheet metal manufacturing industry. in any fusion arc welding process, the weld bead geometry plays an important role in determining the mechanical properties of the weld and hence quality of the weld.  moreover, the geometry of weld bead involves several simultaneously multiple quality characteristics...

Abstract. A temporal analysis was performed on a sample of 100 bright short GRBs with T90<2s from the BATSE Current Catalog along with a similar analysis on 319 long bright GRBs with T90>2s from the same catalog. The short GRBs were denoised using a median filter and the long GRBs were denoised using a wavelet method. Both samples were subjected to an automated pulse selection algorithm to obje...

The design, calibration, and performance of the Mars Orbiter Laser Altimeter (MOLA) receiver are described. The MOLA measurements include the range to the surface, which is determined by the laser-pulse time of flight; the height variability within the footprint determined by the laser echo pulse width; and the apparent surface reflectivity determined by the ratio of the echo to transmitted pul...

We present analysis and numerical simulations of a new method to sense atmospheric wavefront distortion in real time with Rayleigh beacons. Multiple range-gated images of a single pulse from the laser are used to determine each phase map, providing an advantage over other methods in that photon noise is substantially reduced for a given brightness of the beacon. A laser at about 350 nm projects...

The four-dimensional Hodgkin–Huxley equations are considered as the prototype for description of neural pulse propagation. Their mathematical complexity and sophistication prompted a simplified two-dimensional model, the FitzHugh–Nagumo equations, which display many of the former’s dynamical features. Numerical and mathematical analysis are employed to demonstrate that the FitzHugh–Nagumo equat...
