هدف هذا البحث هو دراسة تقريب مبسط من أجل تصميم مضخمات أولية نقل ممانعة منخفضة الضجيج باستخدام ترانزيستورات ثنائية القطبية من أجل المستقبلات الضوئية. اِشْتُقَّتِ الحلول التحليلية من أجل الانحياز الأمثلي و ضجيج تيار الدخل المكافئ. ثم أُنجزت الدراسة بإجراء مقارنة بين الدارات المصممة. حسِب ضجيج تيار الدخل المكافئ بإدخال المعاملات إلى و باستخدام برنامج مكتوب matlab باستخدام برنامج محاكاةmultisim من أجل كشف إشارة نبضية بعرض نبضة 30ns.
The aim of this research is to study a simplified approach for the design of low-noise bipolar transimpedance preamplifiers for optical receivers. Analytical solutions for optimum biasing and minimum equivalent input-noise current were derived. The study was achieved by doing comparison between the designed circuits. The equivalent input noise current was calculated by entering the parameters in Matlab program and using Multisim as a simulation tool to detect a pulse signal of 30ns width.

Due to scientific and technical advances in industrial electronics, SRMs have become one of the most attractive motors in recent decades.
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.
Lemmatization aims to reduce the sparse data problem by relating the inflected forms of a word to its dictionary form. Most prior work on ML based lemmatization has focused on high resource languages, where data sets (word forms) are readily availabl
e. For languages which have no linguistic work available, especially on morphology or in languages where the computational realization of linguistic rules is complex and cumbersome, machine learning based lemmatizers are the way togo. In this paper, we devote our attention to lemmatisation for low resource, morphologically rich scheduled Indian languages using neural methods. Here, low resource means only a small number of word forms are available. We perform tests to analyse the variance in monolingual models' performance on varying the corpus size and contextual morphological tag data for training. We show that monolingual approaches with data augmentation can give competitive accuracy even in the low resource setting, which augurs well for NLP in low resource setting.
Food Industries are among the most important and ancient industries in Syria. The most famous kinds of
it are: Yogurt and cheese industries, biscuit and juice industries.
Food industries' factories are special because of its many production lines a
nd its machines and of the
preparation needed.
The purpose of this research is to study noise resulted by machines in companies of food industries by
measuring noise levels with an anchor equipment and comparing the results with international standards
in order to estimate the amount of dosages that workers in industrial establishments face, and then to
conclude appropriate recommendations to reduce noise levels.
In this paper, A random modeling has been performed for
gyroscopes' components noise in unit measurements inertial
Crossbow IMU400CD MEMS by Alan Variance. Three random
components were discriminated in the noise sensors in addition to
the estimat
ed coefficients of these components, while the technical
bulletin did not mention but one component. Knowing the random
noise type gives the ability to use it as an output component of the
navigational system; estimating it with the navigation support
means such as GPS or magnetic compass or ... etc. enables to
correct gyroscopes out.
Inertial sensors Gyroscopes are gaining nowadays more and
more research interest in a variety of transport fields (i. e. land, sea
and air). Recent efforts are going towards developing those
traditional electromechanical models to electronic manufacturer
microenvironment technology called Micro Electro Mechanical
System (MEMS).
But in return MEMS gyroscopes suffer precision low when
compared to other types as a result of errors, many appear on the
output of particular random errors that can't be deleted
methodologies calibration known, so it is classified as a type of
noise or random processes where they are modeled using random
modeling techniques stochastic Modeling to identify and
distinguish types of noise in the sensor output. Among the most
famous of these techniques mode Allan Variance (AV).
