تستطيع أجهزة القيادة السيرفو هوائية توليد قوى و سرعات عالية و تحريك العناصر بشكل دقيق جداً و سريع. و بمساعدة الصمامات التناسبية صار بمقدورنا التحكم بدقة الحركات و سرعتها في الدارات السيرفو هوائية. و بحسب المهمة المطلوبة، تستخدم الأسطوانات الخطية في معظم الأحيان. و قمنا بنمذجة نظام سيرفو هوائي باعتماد صمامات هواء تناسبية بملف واحد و بملفين تناسبيين للتحريض و القيادة. برهنا هنا أنه من الممكن اختيار حجم عناصر الأنظمة السيرفو هوائية و مواصفاتها، بالتشغيل أولاً على النموذج المحول إلى الخطي، و من ثم فحص التأثيرات الكلية لهذا الاختيار مع نموذج النظام اللاخطي الكامل. و هذا يساعد على اختيار عناصر دارات الأنظمة السيرفو هوائية بشكل أفضل، و يسهل على المصمم تنفيذ الدارات الفعلية المعقدة التصاميم في مجالات الصناعات التي تستخدم مثل هذه التقنيات بشكل مبسط و دقيق بحيث تحقق الوثوقية المطلوبة منها بأقل التكاليف و الجهود المبذولة للحصول على النتائج المرجوة.
Servo pneumatic control systems are able to generate a big forces and high speeds with a high accuracy. Thanks to proportional valves we are able to control the accuracy and speeds of motions in servo pneumatic circuits. Depending on the goal, almost we use the linear cylinders. And we achieved a simulation of servo pneumatic system using a single and double solenoid proportional valve for inducting and control. And we confirmed here, that we can choose servo pneumatic components, sizes and specifications by working on the model translated into linear, then checking the effects of this model comparing with the complete nonlinear system. This will help in choosing the components of servo pneumatic systems more easily and helping the designer to achieve more complicated actual systems with more durability and less cost and efforts to achieve the needed results.

The quick consuming of products and the strong competition
between producers caused to increase the complexity of products, so
the digital factory became a need between design and producing
actually to achieve a production system with a shorter ti
me and
optimal design and parameters without engineering modifications.
This research offering a reference model basing on a complete
framework between the engineering applications to build a
computational model with a single core based on the integration
between three dimensions modeling and automation of application
for digital factory concept, to optimize the design of achieving the
ideal execution of actual production system. Where we achieved the
control of three-dimensional computer model according to process
automation exactly as in actual through integrating tools, where the
percentage of exact between the real factory and digital factory was
83% by using the time of process as the main factor for comparison
in this evaluation.
Recommendation systems are the systems thathelp users to select
suitable items from a large collection of items based on their tastes
and interests. Such systems have become one of the most powerful
tools in electronic commerce and social websites
. Nonetheless ,
using these systems in e-commerce websites faces many drawbacks
such as: cold start-up, scalability and sparsity.
In this paper, we present a solution to cold-start-up problem, and
compare between many association rule algorithms to select the
most suitable one to solve the scalability and sparsity problems.
Recommender systems represents a class of systems designed to help individuals deal with information overload or incomplete
information. Such systems help individuals by providing recommendation through the use of various personalization
techniques
. Collaborative filtering is a widely used technique for rating prediction in recommender systems. This paper presents a
method uses preference relations instead of absolute ratings for similarity calculation.
The result indicates that the proposed method outperform the other methods such as the Somers Coefficient.
إن الهدف الأول للإرتيابات الميكانيكية-البصرية هو تحسين الأداء الوظيفي للنظم البصرية و عدم تراجعها في
ظروف الإستثمار القاسية و أيضاً تحديد دقة و كلفة التجميع حسب الحساسية و الوظيفة المطلوبة من النظام.و كما نعلم، فإنه تحت تأثير الظروف المحيطية من حرار
ة و اهتزاز و صدم و رطوبة و ضغط ...الخ، يتغير موقع و أشكال العناصر البصرية ضمن الحامل المعدني الحاضن لتلك العناصر و هذا يعني خروج المحاور البصرية لتلك العناصر عن المحاور الميكانيك للحامل المعدني الحاضن.
In this paper we consider the properties of linear systems by means of
directed graphs and numerical structures. We also state efficient algorithms
for determining an approximate number of the non-zero terms within
determinants' expressions of the
ir matrices. The stated algorithms make use of
trees representing numerical structures which contains the indices of the nonzero
terms.
This paper yields interesting results used in practical engineering
applications which include linear systems with sparse matrices, for example:
networks, electronic circuits, earth velocities boxes (gearboxes), multi-works
systems ...etc.
