تهدف هذه المقالة إلى استخدام المعوضات التزامنية الساكنة في حالتين أولاً عندما تكون مجمعة أي تمثل معوض واحد في مكان واحد من الشبكة المدروسة باستطاعة واحدة و هي الاستطاعة المتطلبة (المطلوبة) للشبكة المدروسة، و ثانياً عندما تُقسّم استطاعة التعويض اللازمة على عدة معوضات تزامنية ساكنة باستطاعات مناسبة و تُربط في الأمكنة الأفضل (الأكثر ملائمة) من الشبكة المدروسة، و ذلك لتحسين زمن الفصل الحرج لنظام قدرة كهربائي متعدد الآلات IEEE-9 و بالتالي تحسين الاستقرار العابر له (استقراره العابر).
This paper aims to use Static Synchronous Compensators (STATCOMs) in two cases combined or distributed, where it act in the first case as one compensator at one placement of electrical network, for the same required power of studied network, and distributed compensators as multi-STACOM with suitable powers in the second case where they are connected at the best placements of studied network, for improving critical clearing time of IEEE-9 nodes test system and its transient stability.

This paper tries to clarify the impact of parallel and serial compensation of power transmission lines on the
performance of distance relays which protect these lines. To this end, power system analysis software
(NEPLAN) will be used for explaining
distance relay behavior in the presence of different parallel or serial
reactive power compensators, with main types of faults that may occur in different locations on the protected
line.
In this paper, Syrian power transmission network is simulated using (NEPLAN) software, and three reactive
power compensators: parallel (STATCOM), serial (TCSC), and unified (UPFC), are used to compensate
reactive power on transmission line. Several simulations, in many cases are carried out to illustrate the
impact of fault type and location on the measured impedance seen by the distance relay.
The objective of identifying the impact of reactive compensators on fault impedance seen by distance relay
(i.e. fault location), is to determine the possible ways to resolve the problem and improve the performance of
transmission line protection.

Smart shorthand, to display video content, is one of the main problems in computer vision
literature, because it is important to reduce the size of video storage in various media,
especially in mobile phones and monitoring cameras, and reduce the t
ime needed to watch
video.
The smart shorthand process is to build software capable of displaying and save important
content from the viewer, which contains new details, either in terms of the image or in the
accompanying voice and deleting scenes with repeated content.
In this research, a new methodology was introduced to extract new scenes in the image and
sound, without affecting the continuity of motion within the video, and in a manner that
ensures continuous viewing. The methodology relied on two basic algorithms: the first
algorithm works to extract scenes with variable details in the image, based on the
eigenvalues of the scenes, which show a significant change in the details of the scene,
while the second algorithm is based on the extraction of sound with variable details, based
on the algorithm introduced in 1985 from [1], which can encode the sound signal with a
double-value frame 1 or 0, in the signal area containing details that takes value 1, while in
the non- Details takes value 0, the two algorithms are executed synchronously, and thus the
variable scenes and the adjacent acoustic signal are drawn.
The methodology used to work on large video clips in terms of movement of objects
within them has achieved very good effectiveness, great accuracy in synchronization
between the scenes and sound adjacent to them.
This paper presents Imperial College London's submissions to the WMT21 Quality Estimation (QE) Shared Task 3: Critical Error Detection. Our approach builds on cross-lingual pre-trained representations in a sequence classification model. We further im
prove the base classifier by (i) adding a weighted sampler to deal with unbalanced data and (ii) introducing feature engineering, where features related to toxicity, named-entities and sentiment, which are potentially indicative of critical errors, are extracted using existing tools and integrated to the model in different ways. We train models with one type of feature at a time and ensemble those models that improve over the base classifier on the development (dev) set. Our official submissions achieve very competitive results, ranking second for three out of four language pairs.
The Research suggests a novel model aims to reduce the time of search for image
files by proposing a new indexing mechanism to avoid the plague algorithm used with
indexing so that the access time to these files becomes as less as possible.
The fi
rst stage in this paper is to clarify the importance of archiving in organizing
files via designing a database, storing images in it and recording the times needed to
obtain the required files from the database. Then the indexing process for image files
stored in the database is applied by proposing a new algorithm -B+ Tree enhanced- for
organizing image files according to a certain mechanism to facilitate accessing any file,
conducting queries and recording the times used to get those files from the database to
compare them with the times required to access files before indexing in order to show the
efficiency of the proposed method.
This paper introduces a system to recognize labels of time plans, where labels are
extracted from time plan. This labels are images, so spatial segmentation is used to extract
images of labels only. Size of images of labels are made same using medi
an's algorithm for
two purposes. The first one is to create database training for used neural networks. The
second is to recognizing's processing. Two methods of recognizing are dependent on using
neural networks technic: classification using perceptron network and recognizing using
back propagation network. Perceptron network is built to take image as input and to give
classification index as output for label. Then label is recognize dependent on stored table
of ASCII for label. Back propagation network is designed to recognize images for all
letters of English alphabet that are used in time plan. Results of research appear efficiency
of designed system to recognize labels of time plan from their images for both methods
after system had been applied on three time plans.
