A number of Lnx Oy rare-earth oxides where Ln = La, Ce, Pr, Nd, Sm, Eu, Tb,
Dy and Er, x=1, 2, 4, 6 and y=2, 3, 7, 11 have been studied by powder
diffractometry and pycnometry coupled with the simulation of their lattice
dimensions by empirically derived pair potentials using the GULP code.
Crystallographic analysis showed the oxides exist in the tri, tetra and mixed tri-tetra
valency with Bravias lattices: hexagonal- P, cubic- I and cubic- F as a result of the
oxidation state assumed by the Ln element that may be caused by the nature of the
oxide or preparation process involved. Unit cell volumes of the oxides that exhibit
identical Bravias lattices reflect a behavior that can be correlated with the atomic

Image registration plays a significant role in the medical image processing field. This paper proposes a development on the accuracy and performance of the Speeded-Up Robust Surf (SURF) algorithm to create Extended Field of View (EFoV) Ultrasound (US) images through applying different matching measures. These measures include Euclidean distance, cityblock distance, variation, and correlation in the matching stage that was built in the SURF algorithm. The US image registration (fusion) was implemented depending on the control points obtained from the used matching measures. The matched points with higher frequency algorithm were proposed in this work to perform and enhance the EFoV for the US images, since the maximum accurate matching po

In this study, four sampling stations were selected from two locates on the
Tigris river (Baghdad region) and others on the Euphrates river (Al-Anbar
Governorate) in order to determine concentrations, seasonal variation and pollution
intensity assessment of heavy metals (Ni, Cu, Pb, Mn and Cd) in the two rivers
sediments. Distribution of studied metals showed that stations in the Tigris river
generally had higher concentrations than stations in Euphrates river. Manganese was
found at high concentrations in all studied stations and ranged between 200 - 500
ppm, while Cd was found at the lowest concentrations and ranged between not
detected to 1.8 ppm during study period. Based on index of geoaccumul

In this paper, we characterize the unitary composition operator pC on the Hardy space 2H where p is a special automorphism of a unit open disk U such that. In addition to we study the compactness and essential normality of and give some other partial results.

A digital elevation model (DEM) is a digital file of terrain elevations for ground positions. It is a raster representation of the elevation of the ground and objects, such as buildings and trees, with pixel values in the images, as well as the wide range of uses and applications. In this research, the Easting, Northing, and Elevation, data set had been gathered, they collected by performing field survey using global Positioning system (GPS). Modified an interpolation method had been presented it depends on Quadrant and Octant methods to produce a DEM surface. Some classic techniques such as Nearest neighbor and universal Kriging, have been used for comparison purpose with the results of the new technique. A new technique has been used i

In this paper, an modify minimum eigen values technique is introduced to detect
edge points and outline the boundaries of objects within an image. The presented
edge method is performed by utilizing 3×3 and 5×5 windows, and counting the
eigenvalues within each. The minimum eigen value then adopted to replace the
window's center which finally produces an image. Two types of image samples were
used to test the propused method. Sobel type of edge detection then was applied and
the results were better in edge detection obviously.

Adult and nymph stages of German cockroaches Blatilla germanica were infested with two entomopathogenic nematodes, Steinernema carpocapsae and Heterorhabditis bacteriophora in vitro at 15, 20, 25o C. Results showed that S. carpocapsae was more virulent than H. bacteriophora at all temperatures over the exposure times of 24, 48 and 72 h. Infection of nymphs by S. carpocapsae at 20o C caused 100% mortality after 72h and 100% mortality of adults at 25 o C after 72h. Reproduction of S. carpocapsae significantly increased at 25o C after 72 h compared to H. bacteriophora.

The aim of the current paper is to resolve the non-uniqueness in gravity interpretation through searching for singular points in the gravity field that are coincide with causative body vertices. The Absolute Second Horizontal Gradient (ASHG) method is used to locate the horizontal reference location of the body, while its amplitude could be used to define body corner depth. Intelligent use of the ASHG method could help in differentiating between basin and intrusion structures from their gravity effect and could facilitate the interpretation in forward modeling and constrain inversion modeling to maximum limit. The method is tested by using many synthetic examples with different types of shapes. A real data is used to examine the method a

In this study, a qualitative seismic velocity interpretation is made up through using 2D-seismic reflection data on Luhais oil field in southern of Iraq which is situated at about 105 Km to the east from the Basra city. Luhais oil field was chosen to study the type and nature of the distribution of the seismic velocities of Nahr Umr and Zubair Formations in order to show its explorational importance, where these formations contain abundant quantities of hydrocarbons. Picking of the tops of Nahr Umr and Zubair was carried out from the synthetic seismogram which is calculated from sonic-logs and check shot of well Lu-2. Velocity model was obtained via using an implementation of Petrel program version, 2013 and was corrected according to to

Object detection in real time is considered as a challenging problem. However, it is very important in a wide range of applications, especially in field of multimedia. The players and ball are the most important objects in soccer game videos and detecting them is a challenging task because of many difficulties, such as shadow and illumination, ball size, ball occluded by players or merged with lines, and similar appearance of players. To overcome these problems, we present a new system to detect the players and ball in real-time by using background subtraction and Sobel detection. The results were more accurate and approximately two times faster than those using only background subtraction.
