This research includes prepare magnetostrictive compound at ratio x = (0.0, 1.0) by ceramic method at 1200 ℃ sintering temperature. studied some of structural properties by X-ray diffraction technique, and mechanical properties by Fourier-transform infrared FT-IR technique. This is to determine the speed and frequency of ultrasonic waves that's can be generated using the prepared compound. The results show formation the cubic spinel structure of ferrite, and values of Average crystallite size at nm. We observed at ratio x = 1.0 increase in values of Average crystallite size, lattice parameter, and decrease in values of density, and Young's coefficient. The results also showed the frequency of ultrasonic generated at the kHz and MHz ranges, the speed and frequency of the ultrasonic waves generated by are higher than the speed and frequency of the cobalt Ferrite .

This work includes study of Co Zn-ferrite samples doped by Ni which prepared by Ceramic method. Then verified that it had spinel structure by using XRD. In addition we study properties such as electrical resistivity , electrical conductivity , dielec
tric constant and loss coefficient. And also we have studied variations of this properties in terms of temperature at different frequencies in the range of (20 -105) Hz.
Pairs of electron-holes are produced in the space-charge region of a diode pn
heterojunction as a result of an accelerated electron beam collisions having
enough energy larger or equal (≤ ٥٠ kev). Due to the intrinsic electric field an
electric cu
rrent will flow (Electron beam induced current EBIC) in an
appropriate external electric circiut. When an external forward electric field is
applied an electric current IF will flow, helping in electron-hole which
combination produc an additional cathodo-lumines-cence. the study of cothodolumines-
cence intensity variations will give electronic properties and electric
structure of the space - charge.
This work aims to find the differential scattering cross-section
for X-ray
scattered by aluminum target with angles in intervals in accordance to both
polarization cases ( completely – partly).
In addition, the relative scattered intensity and po
larization degree have been
presented as a function of scattered angles and the extreme values are found for each curve.
In this paper, we explore text classification with extremely weak supervision, i.e., only relying on the surface text of class names. This is a more challenging setting than the seed-driven weak supervision, which allows a few seed words per class. W
e opt to attack this problem from a representation learning perspective---ideal document representations should lead to nearly the same results between clustering and the desired classification. In particular, one can classify the same corpus differently (e.g., based on topics and locations), so document representations should be adaptive to the given class names. We propose a novel framework X-Class to realize the adaptive representations. Specifically, we first estimate class representations by incrementally adding the most similar word to each class until inconsistency arises. Following a tailored mixture of class attention mechanisms, we obtain the document representation via a weighted average of contextualized word representations. With the prior of each document assigned to its nearest class, we then cluster and align the documents to classes. Finally, we pick the most confident documents from each cluster to train a text classifier. Extensive experiments demonstrate that X-Class can rival and even outperform seed-driven weakly supervised methods on 7 benchmark datasets.
Basalt is classified as a isotropic rock in according to its mechanical
properties. But gypsum is considered isotropic transverse rock . coming
the mechanical parameters values joins practice direction of parameters
.
By using a nondestructive me
thod such as the ultrasonic test which
depends on understanding the effectual of mechanical properties upon
speed of ultrasonics inside rocks , one can indirectly predict the
mentioned parameters
Tests were completed within 35 gypsum and 11 basalt rocks specimens
which collected by completions under the direction of General
Organization for Land Development ( Directorate of Geological
Investigation).
