يهدف هذا البحث إلى تحويل بيانات الطبقي المحوري المحوسب لعظم الفخذ المصاب بالسرطان إلى نموذج ثلاثي الأبعاد, و تصميم البديل المعدني للمنطقة المصابة و تحليله في برامج التحليل الميكانيكي, من أجل دراسة وثوقيته و ملاءمته من حيث توزع الإجهادات و القوى تماماً كما لو كان في جسم المريض بعد التركيب و بالتعاون مع طبيب الجراحة العظمية, يتم الاعتماد على برامج CAD الخاصة بالعمل الميكانيكي الطبي المشترك حيث نستخدم برنامج Mimics لقراءة صورة الطبقي المحوري و برنامج 3MATIC من أجل تحويل الصورة إلى نموذج رقمي ثلاثي الأبعاد بعد عملية توليد السطح و الحجم للبديل العظمي, و تتم عملية تحليل الإجهادات و القوى التي ستتعرض لها منطقة التعويض في برنامج COMSOL, حيث تبين بعد التصميم و التحليل أن البديل ملائم ميكانيكياً و لا يحوي مناطق خطرة بعد تطبيق الحمل المتوقع.
This research aims to convert CT data of hip bone that sufferining cancer to 3D model, and designing metal implant of the infected area on the mechanical analysis programs, to study operability and convenience in terms of distribution of stresses and forces just as in patient’s body after installation and under the guidance of the bone surgeon.By depending on Mimics software to read the CT image and 3MATIC to convert the image to 3D digital model after generation the surface and the volume of the implant, the analysis process of stresess and forces in COMSOL software. Where after design and analysis the metal implant was appropriate mechanicaly and do not contain dangerousareas after the application of the expected forces.

In this paper, the algorithm was designed for cylinders, slots and pockets extraction from
CAD models saved in STL file depending on rule-based method and graph-based method.
Besides, windows application was designed using Visual Studio C# which al
lows the user
to import CAD model and features extraction and view their geometric information
(cylinder diameter, height, cylinder center coordinates, width, height, length for slots and
pockets. In addition, all surfaces that the feature consists from.
The proposed algorithm consists from multi-steps are: dividing input model into multi
surfaces based on RegionGrowing method, next step is cylinder features extraction
depending on rule-based method, slots and bockets extraction depending on graph-based
method, calculating geometric information for each extracted feature.
The results show that the proposed algorithm can extract cylinders, slots and pockets
features from CAD models which saved in STL files and calculates geometric information
for each extracted feature.
Importance and aims of the research
Biomechanics science is interested in studying the dynamic function and the
movement of vital tissues depending on their mechanical properties.
The main objective of this research is to design a digital model of
the human femur
using the engineering software specialized in medical image processing and engineering
design in order to simulate the mechanical behavior. This would provide important medical
information to orthopedic surgeons concerning the paths and the causes of bone fractures
and deformities, and open a new perspectives in prosthetics efficiency enhancement.
Materials and methods
A three dimensional digital model of the femur was produced using the software
DeVIDE v 9.8 for medical image processing. A surface triangular mesh was constructed
and the mechanical response of the model has been simulated using Ansys 14.5.
Results and discussions
We have shown the steps necessary to design a computerized model of femur bone
on the basis of three-dimensional X-ray images. The results showed the distribution of
stresses and displacements of human femur at normal load conditions.
Conclusion and recommendations
It is recommended to adopt the specialized engineering software for the threedimensional
simulation which can be used in different medical applications.
This research presents software programs that have been designed in order to evaluate the reliability in
electrical distribution networks, by calculating the reliability indices for 20 kV distribution feeders. It is
the first study in this field for the distribution network in Syria.
First of all, the mathematical models of reliability have been presented.
GIS software provide manual import tools to maps produced on CAD software to be transformed to geo-database. This operation consumes time and effort. The "transformation" however will not be
adequate unless we analyze the relation between CAD and GI
S software in preparing maps. The question raised here if this relation competitive or integrative? This research tries to answer this matter
by studying it from different angles: modeling, spatial feature, scale, spatial analysis and data management. Analyses reveal that this relation isn't competitive at all, but rather integrative, as CAD
software produce technical\design plans, whereas GIS software are dedicated for the production of general and thematic maps. Thus, CAD based spatial data (topographic, cadastral, master plans) could
be "up-graded" to be efficient in GIS environment. However available tools to make this are basically manual, and for that, an automated approach was developed to execute this upgrade from CAD to GIS.
This new approach was applied and evaluated and the output results were satisfactory accurate, time\effort saving, and indeed didn't miss any of CAD layers. This all could be achieved if being conditioned with the approach constrains.
Online abuse can inflict harm on users and communities, making online spaces unsafe and toxic. Progress in automatically detecting and classifying abusive content is often held back by the lack of high quality and detailed datasets.We introduce a new
dataset of primarily English Reddit entries which addresses several limitations of prior work. It (1) contains six conceptually distinct primary categories as well as secondary categories, (2) has labels annotated in the context of the conversation thread, (3) contains rationales and (4) uses an expert-driven group-adjudication process for high quality annotations. We report several baseline models to benchmark the work of future researchers. The annotated dataset, annotation guidelines, models and code are freely available.
