يعتبر بروتوكول الانترنت Voice Over IP Protocol بأنه اتصال صوتي عبر الانترنت بالغ الأهمية ، و يتميز بجودة الخدمة العالية (Quality of Service) . سنقوم في هذا العمل بتقييم مدى مطابقة خدمة الانترنت في يومنا هذا للتوقعات المرجوة منه عن طريق دراسة أداء البروتوكول Voice over IP وجودة الخدمة الخاصة به (Quality of Service). حيث اعتمدنا على منهجية اختيار المرمزات أولاً ضمن بعض المقاييس للحصول على نتيجة محاكاة لمقارنة و تحليل (QoS). و الذي اعتمدنا به على برتوكولات VoIP في حال وجود عدة مستخدمين مع ثلاثة خوارزميات للمرمزات، و بعد تحديد المشكلة في هذا النطاق أخذنا مجموعة من العوامل بعين الاعتبار نتيجة لتأثيرها على أداء الصوت, مثل jitter و Delay . يحاكي هذا العمل ثلاثا من اكثر المرمزات شيوعاً ( تحويل الصوت من تناظري لرقمي و ضغط الحزم ) و هي G.711 و G.723.1 و G.729 . إن الهدف الرئيسي هو تحقيق أداء صوت بجودة عالية من خلال اتخاذ القرار المناسب في اختيار مرمز الصوت.
Voice over IP Protocol is an important Internet voice connection, characterized by high quality of service. In this work, we will assess how today's Internet service matches its expectations by examining the performance of the Voice over IP protocol and its quality of service. We have relied on the method of selection of encoders first within some parameters to obtain the simulation result of the comparison and analysis (QoS). Which we adopted on VoIP protocols in the case of multiple users with three algorithms for the symbols, and after determining the problem in this range, we took a number of factors into account due to their impact on sound performance, such as jitter and Delay. This action simulates three of the most common encoders (analog audio conversion and packet compression), G.711, G.723.1 and G.729. The main objective is to achieve high-quality sound performance by making the appropriate decision in the choice of sound encoder.

Adapter modules have emerged as a general parameter-efficient means to specialize a pretrained encoder to new domains. Massively multilingual transformers (MMTs) have particularly benefited from additional training of language-specific adapters. Howe
ver, this approach is not viable for the vast majority of languages, due to limitations in their corpus size or compute budgets. In this work, we propose MAD-G (Multilingual ADapter Generation), which contextually generates language adapters from language representations based on typological features. In contrast to prior work, our time- and space-efficient MAD-G approach enables (1) sharing of linguistic knowledge across languages and (2) zero-shot inference by generating language adapters for unseen languages. We thoroughly evaluate MAD-G in zero-shot cross-lingual transfer on part-of-speech tagging, dependency parsing, and named entity recognition. While offering (1) improved fine-tuning efficiency (by a factor of around 50 in our experiments), (2) a smaller parameter budget, and (3) increased language coverage, MAD-G remains competitive with more expensive methods for language-specific adapter training across the board. Moreover, it offers substantial benefits for low-resource languages, particularly on the NER task in low-resource African languages. Finally, we demonstrate that MAD-G's transfer performance can be further improved via: (i) multi-source training, i.e., by generating and combining adapters of multiple languages with available task-specific training data; and (ii) by further fine-tuning generated MAD-G adapters for languages with monolingual data.

This article reviews the structure of an integrated navigation system made up of unit inertial sensors manufactured by MEMS technology, a GPS Receiver unit, magnetic compasses manufactured by MEMS technology, and a high barometric sensor. The integra
ted system is built using an Extended Kalman Filter (EKF). This reviewing is performed with the use of a closed-loop system that has simple integration namely the Loosely Coupling Integration.
After conducting several air tests to collect real navigational data, antipersonnel navigational data has been used to do the integrated navigation system analysis with EKF environment in the software Matlab.
It has been noticed after the analysis that the complementary horizontal navigation system error does not exceed 50 m. With deliberate withholding of GPS data for different periods in order to test the performance of the integrated navigation system in case of withholding the GPS signal, we have found that the integrated navigation system achieves good accuracy, where the horizontal error does not exceed 200 m value when the withholding GPS data for 120 seconds. This can be considered as small and acceptable values compared with the horizontal error value for inertial navigation unit stim300 when operating independently of up to 8200 m.
The employment of multiple antennas at the transmission and reception side for the
formation of a MIMO system contributed significantly to improve the reliability of
transmission and increase the data rate. In the last decade, this system represent
ed the
backbone of wireless communications which paved the way for the development of many
techniques in this area. Therefore, there is a need to study the most important of these
techniques and compare its performance analysis.
This research deals with several closed-loop MIMO techniques : (P-OSM) which
maximizes the minimum Euclidean distance in the received signal constellation in order to
reduce the bit error rate, (X and Y Precoders) which improve the diversity gain of MIMO
system. The aim is to study and analysis the performance of previous techniques in
practical scenarios of wireless communication systems in the presence of limited feedback
channel. The results shows the possibility of practical employment of the P-OSM
technique in a simple way compared to other techniques due to its good performance and
low complexity order.
