Today, seawater and brackish water desalination is a subject of concern of many researchers all over the world. The recourse to the desalination by distillation using solar energy represents an appreciable element of the water resource and constitute

With the aim of mitigating the problem of salinity of purified waste water of the STEP (waste water treatment plant) of Ouargla, one proposed to study the possibility of integration of solar energy to solve the problem of this water intended for the

We propose a fast and efficient frequency-domain implementation of a modified parabolic Radon transform (modified PRT) based on a singular value decomposition (SVD) with applications to multiple removal. The problem is transformed into a complex line

The stacking of long-offset seismic data requires a nonhyperbolic traveltime function that depends on two-way traveltime, normal moveout (NMO) velocity and effective anellipticity. Based on a standard fractional approximation, a new parameterization

We formulated two coherency measures, based on the bootstrapped differential semblance (BDS) estimator, that offered higher resolution in parameter tracking than did standard normalized differential semblance. Bootstrapping is a statistical resamplin

We present a fast and efficient frequency-domain implementation of a modified parabolic Radon transform (modified PRT) based on a singular value decomposition with applications to multiple removal. With a change of variable, the problem is transforme

Y-faujasite previously impregnated with aqueous wastes containing mainly UO 2 2+ cations ( ca 1000 ppm) showed interesting catalytic activities in n-octanol-1 amination. The reaction was run in gas phase and the catalytic performances were investigat

We present an automatic algorithm to implement nonhyperbolic velocity analysis in VTI media. The approach is based on the use of nonhyperbolic traveltime equations that are accurate at large offsets and in anisotropic media. This is combined with an
