سيتم في هذا البحث دراسة أداء خدمة نقل الصوت VOIP عبر شبكة الانترنت من خلال مقارنة أداء بروتوكول تهيئة الجلسة SIP و بروتوكول H323 و تقييم محددات الجودة كالتأخير الزمني، نسبة ضياع الرزم و عدد المكالمات الفعالة في الشبكة مع تغير عدد المستخدمين للشبكة. لتحقيق ذلك سنقوم باستخدام تقنية المحاكاة المناسبة و هي OPNET.
In this paper, we assess the Voice Over Internet Protocol performance by comparing the performance of two protocols used in VOIP such as SIP and H.323. Moreover, we evaluate the quality indicators such as delay and packets loss. For this purpose OPNET simulator is used as suitable simulation technology.

Research summary
تتناول هذه الدراسة تأثير تغير عدد المستخدمين على أداء بروتوكولي إرسال الصوت عبر الإنترنت SIP و H.323. يتمحور البحث حول تقنية VOIP التي تتيح إجراء المكالمات الهاتفية عبر الإنترنت باستخدام إشارات رقمية بدلاً من الإشارات التماثلية المستخدمة في شبكات الهاتف التقليدية. تم استخدام برنامج OPNET لمحاكاة الشبكة ودراسة محددات الجودة مثل التأخير الزمني ونسبة ضياع الرزم وعدد المكالمات الفعالة. أظهرت النتائج أن بروتوكول H.323 يتفوق على SIP من حيث تقليل التأخير وضياع الرزم، بينما يتفوق SIP في عدد المكالمات الفعالة. توصي الدراسة باستخدام H.323 في التطبيقات التي تتطلب جودة عالية وزمن تأخير منخفض مثل المحاضرات عن بعد والتطبيقات الطبية، بينما يمكن استخدام SIP في التطبيقات التي تتطلب عدد مكالمات أكبر مثل التواصل الاجتماعي والدردشة.
Critical review
دراسة نقدية: تقدم هذه الدراسة فهماً عميقاً لأداء بروتوكولي SIP و H.323 في بيئات مختلفة، مما يساهم في اتخاذ قرارات مستنيرة حول استخدام كل منهما. ومع ذلك، يمكن تحسين الدراسة من خلال تضمين المزيد من السيناريوهات الواقعية التي تعكس تنوع التطبيقات الحديثة. كما أن استخدام بروتوكولات أخرى مثل WebRTC يمكن أن يضيف قيمة إضافية للبحث. من المهم أيضاً النظر في العوامل الاقتصادية والتكلفة التشغيلية لكل بروتوكول، حيث أن هذه العوامل تلعب دوراً كبيراً في اختيار البروتوكول المناسب.

The process of transfer a speech signal by high confidentially and as quickly as possible through the Internet needs to develop compression and encryption technology for a speech signal, so as, to reduce its size and make it understandable to persons
not authorized to listen to.
A system was designed to encrypt the voice over Internet Protocol (VoIP) and use compression technique for the purpose of reducing the size of data and send it over the network, (A_law PCM) algorithm was used the to compress audio data. Then algorithms of Triple Data Encryption Standard (TDES) and Advanced.
Encryption Standard (AES) were applied. A new encryption algorithm was proposed based in its work on the block cipher encryption system called the Direct and Reverse algorithm, which based on three basic steps, firstly expand the initial key, secondly direct the encryption of each round in one direction, and finally substitute (Bytes) as used in the Compensation Box in AES algorithm by making it moving. In general compression ratio was calculated and it was (50%) and the results of the correlation coefficient for the proposed algorithm was compared with the results of (AES, TDES) algorithms.
With the rapid growth of the size of the data stored in the cloud systems, the need for
effective data processing becomes critical and urgent. This research introduces a study of
the most important characteristics of databases management systems: H
ive, SQLMR, and
MariaDB Galera. Hive is a cloud database management system. SQLMR is a hybrid
system, which depends on the integration between the cloud and traditional systems
capabilities. While MariaDB Galera is a traditional database management system
developed to cope with the cloud characteristics. In this research, we show the most
important developments that have been on those systems, and then we compare their
performance in data processing based on the execution time of query operations with the
change of the volume of data. That is to identify the performance of those systems
practically and to know the developing requirements for access to optimized data
management system, and to help users in the selection of the database system that achieves
their requirements in terms of availability and scalability.
This research presents a study with the help of Finite Element Method and the use of
CATIA V5 program to know the behavior of a permissible link - column used in metal
structures at high temperatures (on fire). In this article we will present an an
alysis using the
finite element method using the CATIA V5 program for the effect of different engineering
parameters (plate thickness, screw diameter, reinforcement nerves) on the behavior of
joints used in metal structures on fire. We also studied the effect of the number of bolts on
the stresses and transitions in the link and their comparison with the welding cases. We
studied and analyzed the studied model and obtained the deformation and failure schemes
at high temperatures, the flow charts and the temperatures that show the behavior of this
link to the fire. We also obtained the stress and strain schemes for the link and the transport
and load schemes at different temperatures and the behavior of this link at these different
temperature.
A Vehicular Ad-hoc Network (VANET) is a collection of nodes forming a
wireless network, but the nodes of this network are vehicles with special equipment that
enable them to communicate with each other. VANET protocols have to face high
challenges
due to dynamically changing topologies, link breakage and low vehicular
density. A suitable and effective routing protocol helps to ensure that messages are reached
to their destinations and achieve the desired aim of the application.
In this research, we present an analysis of the performance of two major routing
protocols used in these networks, which are AODV (Ad hoc On-Demand Distance Vector)
and GPSR (Greedy Perimeter Stateless Routing). This analysis is based on various
parameters such as end-to-end delay and average dropped packets, in order to find the best
protocol which can be used in the network with low density at the junctions. To achieve
this purpose, we used a simulator OPNET_17.5. Depending on the simulation results, we
have obtained and the analysis and comparison of two protocols at different low density
contract. We found that GPSR protocol has better performance end-to-end delay and
average dropped packets are used as the performance metrics, and is better for VANET
under the low vehicular density simulation scenario at junctions.
Voice recognition includes two basic parts: speech and speaker recognition. These
recognition processes consider as the most important processes of modern technologies,
many systems has been developed that differ in the methods used to extract feat
ures and
classification ways to support recognition systems of this type.
The study was conducted in this research on the previous subject, where the system
is designed to recognize the speaker and his voice orders and focus on several
complementary algorithms to carry out the research. we conducted an analytical study on
MFCC algorithm used in the extraction of features, and it has been studying two
parameters the number of filters in the filters bank and the number of features that taken
from each frame and the impact of these two parameters in the recognition rate and the
relationship of these two parameters on each other. It was the use of feed forwarding back
propagation neural networks performance analysis as characteristics and we analyze the
performance of the network to gain access to the best features and components to the
process of achieving recognition. And it has been studying Endpoint algorithm that used
to remove periods of silence and its impact on voice recognition rates.
