Masers found in massive star-forming regions can be located precisely in sixdimensional phase space and therefore serve as a tool for studying Milky Way dynamics. The non-random orbital phases at which the masers are found and the sparseness of current samples require modeling. Here we model the phasespace distribution function of 18 precisely measured Galactic masers, permitting a mean velocit...

GPR and reflection seismics share common physical and methodological bases but are sensitive to different subsurface physical properties. The peculiarities of the electromagnetic case impact data acquisition, processing and interpretation. We review multi-offset techniques in GPR applications focusing on similarities and differences through examples taken from different subsurface and target co...

Provided the velocity of the medium is known and the the medium does not allow different reflectors to have identical surface seismic measurements that persist under small perturbations of the medium, map migration achieves a one-to-one mapping from surface seismic data to the subsurface seismic image by using the slopes in addition to the location (and time) of the events in the data. In this ...

The effect of Gibberellic Acid (GA3) and Benzyladenine (BA) on Aloe vera was evaluated at pot cultivation conditions. This study was performed in two factorial test based on complete random plan and 4 repeats with 12 treatments. The main factor was included spraying, drip and spraying + drip. Secondary factor was included concentrations of GA3 and BA at 0, 100...

In order to estimate elastic parameters of the subsurface, geophysicists need reliable information about angle-dependent reflectivity. In this paper, we describe how to image nonzero offsets during shot-profile migration so that they can be mapped to the angle domain with Sava and Fomel’s (2000) transformation. CIGs also contain information about how well focused events are at depth, and so pro...

Abstract—Orthogonal Frequency Division Multiplex (OFDM) systems are very sensitive to frequency offset caused by tuning oscillator instabilities and Doppler shifts induced by the channel. The Schmidl and Cox Algorithm (SCA) is quite robust in estimating the frequency offset for systems with large OFDM symbol lengths. It uses two OFDM symbols for training with the first one having two identical ...
