Landsat-7 Enhanced Thematic Mapper Plus (ETM+) sensor offers several
enhancements over the Landsat-5 Thematic Mapper (TM) sensors, including increased
spectral information content, improved geodetic accuracy, reduced noise, reliable
calibration, and matching scenes were recorded by both, and improved spatial resolution
of the thermal band. In this paper, we present some comparisons between Landsat-7
ETM+ and Landsat-5 TM imagery in order to quantify these improvements. Practically,
we find that the ETM+ continues the record of TM observations, and, in many respects,
substantially improves upon the earlier sensor. Specific improvements include lower
spatial noise levels, improved information content, and geodetic a

We consider the general nonlinear regression problem . A
survey of some classical methods and stochastic approximation procedures for
estimating is first given. We solve the nonlinear regression problem by
considering the optimal stochastic approximation procedure by [3],[4]. This leads us
to introduce a new procedure , called "Stochastic Approximation Iterative Least
Square Procedure" SA -ILS procedure. The new procedure is applied to a number of
nonlinear regression models. We report on the results of a simulation investigation
which indicate that the new procedure is highly efficient with respect to the number
of observations required to obtain the parameter estimates for given regression
problem.

     In this work, lead oxide (PbO) thin films were deposited using D.C. sputtering method on a surface of glass substrates and then thermally annealed at a temperature of 473K with annealing times of (1,2 and 3) hours. The structural, morphological, and optical properties of films were determined using X-ray diffraction (XRD), atomic force microscopy (AFM), FT-IR, and UV-Visible spectroscopy. The structure studies confirmed that PbO films are polycrystalline structures in an orthorhombic phase with average grain size (24.51, 29.64, 46.49, 16) nm with increasing annealing time. From AFM, the roughness of the film surface  (3.26, 1.76, 1.61, 1.79) nm as the film annealing time increases. The optical band gap values of the PbO thin fi

    Terrestrial laser scanners (TLSs) are 3D imaging systems that provide the most powerful 3D representation and practical solutions for various applications. Hence this is due to effective range measurements, 3D point cloud reliability, and rapid acquisition performance. Stonex X300 TOF scanner delivered better certainty in far-range than in close-range measurements due to the high noise level inherent within the data delivered from Time of Flight (TOF) scanning sensors. However, if these errors are manipulated properly using a valid calibration model, more accurate products can be obtained even from very close-range measurements. Therefore, to fill this gap, this research presents a user-oriented target-based calibration routine to

In this paper we present a study on Peristaltic of fractional generalized Maxwell viscoelastic fluid through a porous medium. A modified Darcy-Brinkman model is utilized to simulate the flow of a generalized Maxwell fluid in a porous medium in an inclined channel with slip effect. The governing equation is simplified by assuming long wavelength and low Reynolds number approximations. The numerical and approximate analytical solutions of the problem are obtained by a semi-numerical technique, namely the homotopy perturbation method. The influence of the dominating physical parameters such as fractional Maxwell parameter, relaxation time, amplitude ratio, permeability parameter, Froude number, Reynolds number and inclination of channel on

The structural, optical properties of cupper indium gallium selenite (CuIn1-xGaxSe) have been studied. CuIn1-xGaxSe thin films for x=0.6 have been prepared by thermal evaporation technique, of 2000±20 nm thickness, with rate of deposition 2±0.1 nm/sec, on glass substrate at room temperature. Heat treatment has been carried out in the range (373-773) K for 1 hour. It demonstrated from the XRD method that all the as-deposited and annealed films have polycrystalline structure of multiphase. The optical measurement of the CIGS thin films conformed that they have, direct allowed energy gap equal to 1.7 eV. The values of some important optical parameters of the studied films such as (absorption coefficient, refractive index, extinction coeffici

Steganography is one of the most popular techniques for data hiding in the different media such as images, audio or video files. This paper introduced the improved technique to hide the secret message using the LSB algorithm inside the RGB true color image by encrypting it using the secret key transformation function. The key is selecting randomly in the GF (2n) with condition it has an inverse value to retrieve the encrypted message. Only two bits are used for the low byte in each pixel (the blue byte) to hide the secret message, since the blue color has a weak effect on human eyes. The message hidden by the suggested algorithm is less vulnerable to be stolen than other similar applications.

In this paper, we will show that the Modified SP iteration can be used to approximate fixed point of contraction mappings under certain condition. Also, we show that this iteration method is faster than Mann, Ishikawa, Noor, SP, CR, Karahan iteration methods. Furthermore, by using the same condition, we shown that the Picard S- iteration method converges faster than Modified SP iteration and hence also faster than all Mann, Ishikawa, Noor, SP, CR, Karahan iteration methods. Finally, a data dependence result is proven for fixed point of contraction mappings with the help of the Modified SP iteration process.

The Hagiastridae Reidel include Spongodiscacea with two, three or four rayed test comprised of layered spongy meshwork lacking concentric ring or spirl. This family appears to be restricted to the Mesozoic (1, 2, 3). It has ageologic history extending at least as far as the Jurassic. The majority of Hagiastridae species are distinctive and with short range.
Seven species of Hagiastridae: Paronaella ewingi, Halesium quadratum, Patulibracchium inaequalum, Patulibracchium marshensis, Hagiastrum plenum, Crucella messinae, Crucella irwini, have been described. They are frome the upper Jurassic-lower Cretaceous Karimia Formation of northren Iraq.

The s-level of a screened hydogenic atom in a uniform magnetic field of arbitrary strength B have been calculated accurately. First, the related spherical symmetric case )~(2122Brhas been treated by using the linear variational method. The trial wave function is taken as linear mixture of hydogenic and 3D harmonic ascillator wave functions of s-symmetry. Second, the actual nonspherical case)(21222yx is studied by adopting the correction proposed by Mustafa and Chhajlany (Phys. Rev.A,50,(I994),2926). The latter accounts for the difference between the two cases in an appaximate way by utilizing the properties of the 2D and 3D harmonic oscillators.
We start our study with the unsceened hydrogen case to recover their shifted
