This research is based on experimental results of magnetization and magnetic susceptibility of ferrite slab prepared in a previous work with a computerized simulation to find the influence of ferrite slab on a microwave propagation in terms of determining the behavior of attenuation factor .A slab of ferrite Co0.6Zn0.4Fe2O4were prepared by classical ceramic method. We have studied an influence of slab of the CoZn-ferrite its thickness is , loaded in a rectangular waveguide on a propagation of microwaves. The values of the reverse and forward attenuation factor has been found. After that, we choose the location of the slab X0 inside the guide which means the optimum status of microwave propagation has been reached at .

The ESR signal of the Co0.6Zn0.4Fe2O4 ferrite system was recorded at room temperature. The experimental magnetic moment value was estimated by means of integrated intensity of ESR signal and its maximum position. It has been used some theoretical rel
ations were used to estimate the values of magnetic moment of the studied ferrite.
The cation distributions between tetrahedral and octahedral sites were established from the values of magnetic moment.In addition, the lifetimeof energy level was determined.
Substrate Integrated Waveguide (SIW) is an important technology that
helps to get benefit of metal rectangular waveguides and Micostrip,
allowing for microwave circuits with high-performance, high-integrity
and low-cost. Using this technology, mic
rowave circuits with high
performance, small size and high integrity could be designed.
This work aims to analyze the performance of the microwave radio link’s parameters
used to connect different systems and intra systems. Fuzzy logic technique is used to study
the difficulties of the radio link’s parameters based on type of modulati
on, and distance
between the receiver and transmitter. Four parameters are used as an input parameters for
the fuzzy logic system mainly: required power, the length of the microwave radio link,
modulation type and the signal to noise ratio(S/N). The output parameter is determined to
be the microwave link capacity.
Analytical study to select the optimal microwave radio link parameters to examine
the efficiency of the radio link capacity will be shown. Additionally, studying the input and
output memberships of the microwave radio link parameters using fuzzy logic will be
explained.
The telescopic cantilever beam is widely used in different types of cranes. These
structures are flexible; it can expand or shrink according to the operating conditions. The
dynamic changes of the total length of the structure lead to time-dependen
t vibrational
characteristics. In practice, CAD modeling for this case is a challenging matter due to the
nature of the problem of analyzing stress and deformation occurring during the operation
of the crane. This research discusses the feasibility of finding a solution for the design
problems initialized during the failure of the telescopic cantilever beam through the
application of Finite Element Analyses (FEA) in order to find the ideal dimension of the
structure which represents the best design for the telescopic cantilever beam.
The copper wire drawing is one of cold forming operations which
basicly the copper is used as pure material for various diameters &
sections in electrical conductors industry.
By cooperation with S.M.C company for cables industry in
Damascus – Sy
ria, a research has been done during 2 years on rod
breakdown heavy drawing machine -HENRICH - GERMANY- 2
lines- with max productivity 25 ton/24hr.
50 samples of copper wire breaks and deformations have been
studied & analyzed, thus the defects are classified in main statistics
diagrams in gold of give main instructions that contribute in raising
the quality level of local copper wire manufacturing & giving a
whole view about this industry.
