يقدم هذا البحث دراسة هدفها تحسين أداء آلة درفلة الحديد على الساخن , و جعلها مطابقة للمواصفات الدولية حيث تشمل الدراسة مرحلتين: الأولى و تتضمن النمذجة الرياضية و محاكاة آلة الدرفلة . أما المرحلة الثانية فتشمل تطوير و اختبار نظم التحكم البديلة . اختبرت صحة هذا النموذج من خلال تحليل منحنيات الأداء المستخلصة من محاكاتها و مقارنتها مع قيم منحنيات و جداول المحطة الحقيقية المأخوذة من HSRMP و ذلك من خلال تضمين هذا النموذج لبارامترات النظام المميزة و المتغيرات الممثلة للأداء الحقيقي للمحطة , هذا يجعل منه أداة مفيدة تتيح محاكاة أداء المحطة , تفسير سلوك المتغيرات و اختبار الحالات إضافة إلى إمكانية تغير العمل و استراتيجيات التشغيل لتحسين التشغيل بشكل عام . من هذا النموذج أنجز التحليل المبدئي و الذي أثبت إمكانية تحسين أداء المحطة بتنفيذ التعديلات التالية : • تقليل قيمة الثابت التكاملي للنماذج المرتبطة بالحلقات المتوضعة في المرحلة الأخيرة • توحيد كل نسب التغذية الردية للحلقات Fed back . • نقل الدائر ليتوضع في المرحلة الأخيرة . ملاحظة : ان الرمز HSRMP هو اختصار للعبارة Hot Strip Rolling Mill Plant و تعني معمل درفلة الحديد على الساخن .
This paper presents a study aimed at improving the performance of the machine, hot steel rolling, and make them conform to international standards, where the study includes two phases: the first includes mathematical modeling and simulation programming language with a rolling machine. The second phase will include the development and testing of alternative control systems. I tested the validity of this model through analyzes of performance curves derived from simulated and compared with the values of the curves and tables station real taken from the HSRMP. Through ensure this form to the parameters of the system characteristic variables representing the performance of the real station, this makes it a useful tool allows simulation of plant performance, explain the behavior of variables The test cases in addition to the possibility of change work and operating strategies to improve the overall operation. From this model performed the initial analysis, which proved the possibility of improving the performance of the station to implement the following modifications: • Reduce the value of hard integrative models associated with the rings are positioned in the final stage. • unification of all evil ratios for nutrition workshops. • Revolving transfer is located in the last phase . Note: HSRMP ( Hot strip rolling Mill plant ) .

This paper deals with computer simulation methods when constructing the
equipment in iron rolling mill plants for dimensioning machines, which have become more
important in the recent years. And it determines the ideal prerequisites to simulate dri
ving
system for electrical and mechanical subsystems. The drive systems is built around several
components which have their own technology and multiple time-scales: electrical
machines, power semiconductor, control circuits from the firing sequences to the different
regulators. This requires the simulation of both the electrical and mechanical components
in one model. The use of a uniform simulation program offers the possibility to combine in
mechanical modeling with the electrical necessities. This research will be in the description
of the simulation-aided design and its relationship with vibration caused by the twisting
torque using the drive systems.
In this
work a computer model based on finite difference method is
developed to calculate the temperatures and thermal
stresses/strains within the roll under various cooling system
parameters for High Chromium Cast Iron Roll, and study of the
effect of each parameter on thermal Fatigue phenomena in this
roll.
The deep-well pumps are practically and widely used to pump water up
from wells. These pumps are driven by squirrel-cage induction motors
where the pump is directly connected with the induction motor it drives.
They form a pump-motor set or a deep
-well set.
Economioally, the cost of digging a well proportionates with the diameter
of the hole opening.
This diameter is related to the deep-well set dimensions. Whenever the
dimensions of the deep-well set are small, the cost of digging a hole will
be notably less.
From here, in this research we shall test the possibility of desiging a
deep-well induction motor with a voltage of f =150 Hz frequency in a
small size. and in trifold speed of the induction motor which has same
power and functions as the motor with a voltage of f = 50 Hz frequency
and where the essential parameters of the motor aren’t worse than the
motor with f = 50 Hz Frequency.
Nowadays, glycogen synthase kinase 3 (GSK-3) inhibitors become
one of the most important drug targets for the development of their
selective inhibitors serving as promising drugs for the treatment of
many diseases, particularly Alzheimer's disease
. Targeting GSK-3
enzyme has a therapeutic importance in many diseases and is one of
the valuable fields for researchers in both academic research centers
and pharmaceutical companies.
Breast cancer is the most widespread types of cancer among women. An efficient
diagnosis in its early stage can give women a better chance of full recovery. Calcification
is the important sign for early breast cancer detection. Mammography is the m
ost effective
method for breast cancer early detection using low radiation doses. The studies improved
the sensitivity of mammogram from 15% to 30% based on Computer Auto-Detection CAD
systems, which are used as a “second opinion” to alert the radiologist to structures that,
otherwise, might be overlooked. This article summarizes the various methods adopted for
micro-calcification cluster detection and compares their performance. Moreover, reasons
for the adoption of a common public image database as a test bench for CAD systems,
motivations for further CAD tool improvements, and the effectiveness of various CAD
systems in a clinical environment are given.
