من باب الحرص على مواكبة أحدث التقنيات التي تم التوصل إليها عالمياً و بهدف ملاحقة الركب العالمي في مجال التكنولوجيا كان لابد لنا من السعي الحثيث للبحث في أحدث السبل التكنولوجية لتحسين واقع عمل المؤسسات ضمن الجمهورية العربية السورية. يهدف هذا البحث إلى بناء شبكة من المتحكمات المنطقية (PLCs) القابلة للبرمجة مع شاشات (HMI) و أنظمة SCADA و دراسة أنسب البروتوكولات لبناء الشبكة مع تحديد الأسباب. بعد د ا رسة و تحديد البروتوكولات الأنسب لبناء الشبكة, يتم استخدام هذه الشبكة الصناعية المؤتمتة في تحسين الواقع الحالي لشركة المياه في مجال تحصيل بيانات العدادات بالدقة و السرعة المطلوبتين. بنيت الشبكة بالاعتماد على مجموعة من المتحكمات المنطقية القابلة للبرمجة بحيث يتم استخدام كل متحكم لتحصيل البيانات من حي من أحياء محافظة حماة تربط هذه المتحكمات الموزعة عبر موجه مركزي لنقل البيانات إلى المركز الرئيس لشركة المياه ,و للتواصل مع النظام تستخدم واجهات التخاطب البشرية HMI و نظام SCADA لإظهار و تخزين البيانات التي تم تحصيلها تربط هذه الواجهة ضمن الشبكة نفسها الخاصة بالمتحكمات المنطقية القابلة للبرمجة لنحصل بذلك على شبكة صناعية موزعة.
In order to keep up with the latest international technologies which have been achieved recently. We have to search continuously for the technological methods in order to improve the present situation of the institutions in the Syrian Arab Republic. This research aims to build a network of Programmable Logic Controllers (PLCs) with Human Machine Interface (HMI) and supervisory control and data acquisition (SCADA) system, as well as, studying the most suitable protocols to build the network beside identifying the causes of choosing the protocol. After studying and identifying it, we had better to use the automated industrial network to improve the present situation of water company concerning with getting meters data accurately as fast as possible. We build the mentioned network by means of a group of PLCs, so that, each one could be used to get the data for an avenue in Hama city. These distributed controllers would be connected by a central router in order to pass all the data to the water company center. We will use a HMI and SCADA system for showing collected data, controlling, and saving the collected data. This HMI and SCADA system will be connected to the same PLCs, and thus, we will get a distributed industrial network.

The experiment carried out to improve the efficiency of drip
irrigation system , based on soil moisture. The indirect measure of
humidity Was used in the experiment, connected with the pointing
device (separator continued), and a control device pr
ogrammed on a
low humidity degree, which is degree the field capacity of the soil and
which value is 25%, and on a high moisture degree which is saturation degree
at 75%..
Since Electroencephalogram (EEG) signals have very small magnitude, it's very hard
to capture these signals without having noise (produced by surrounding artifacts) affect the
real EEG signals, so it is necessary to use Filters to remove noise.
Th
is work proposes a design of an electronic circuit using a microcontroller, an
instrumentation amplifier and an operational amplifier able to capture EEG signals, convert
the captured signals from analog state to digital one and send the converted signal (digital
signal) to a group of three digital filters.
This paper gives a design of three digital elliptic filters ready to be used in real time
filtering of EEG signals (which preliminary represents the condition of the brain) making
the software part which complements the hardware part in the EEG signals capturing
system.
Finally we are going to show the way of using the designed electronic circuit with
the three designed digital filters, demonstrate and discuss the results of this work.
We have used Eagle 6.6 software to design and draw the circuit, CodeVision AVR
3.12 software to write the program downloaded on the microcontroller, Mathworks
MATLAB 2014a software to design the three digital filters and Mathworks MATLAB
2014a Simulink tool to make the appropriate experiments and get the results.
The research presents a design for an automated checking system for students. The
system takes a picture of the student, then it extracts his/her basic facial features. The
network was trained using the reverse spreading algorithm. If a training da
tabase is
generated for each student consisting of 15 training samples contained of the necessary
facial expressions to identify the student for one time at the beginning of the semester, then
the neural network will be trained on students database to obtain a trained neural network
able to identify the students of each category depending on their physical appearance. That
will result in knowing who attends and who does not attend the session. The system
designed for this purpose was supplied with the trained network. The system provides the
possibility of automated checking for students according to the content of the study giving
the alarm in case of the existence of the picture of a student who does not belong to the
same group.
In this paper, we processed an array which represents the
human hand image to get the characteristics of this image. So,
we used FPGA technique, and the processing operation is
partitioned into three threads which is carried out in parallel.
Each
thread is carried out using the pipeline technique by
partitioning thread into four segments. After that, we evaluated
the speedup that we get in result of using the pipeline technique
and the parallel threads. So, we have the possibility to design an
embedded system integrated into chip (SoC), and using the
mobile phones as integral devices support the software and
hardware resources.

Most of the time, when dealing with a particular Natural Language Processing task, systems are compared on the basis of global statistics such as recall, precision, F1-score, etc. While such scores provide a general idea of the behavior of these syst
ems, they ignore a key piece of information that can be useful for assessing progress and discerning remaining challenges: the relative difficulty of test instances. To address this shortcoming, we introduce the notion of differential evaluation which effectively defines a pragmatic partition of instances into gradually more difficult bins by leveraging the predictions made by a set of systems. Comparing systems along these difficulty bins enables us to produce a finer-grained analysis of their relative merits, which we illustrate on two use-cases: a comparison of systems participating in a multi-label text classification task (CLEF eHealth 2018 ICD-10 coding), and a comparison of neural models trained for biomedical entity detection (BioCreative V chemical-disease relations dataset).
