Nowadays, quantity and the volume of documents used in the modern world are growing According to the statistics; the volume of corporate e-textinformation is doubling every three years. Document automation market in the world increased by about 20% per year, analysts said.Currently, many countries in the world to createthe preconditions for growth and the rapid development of this market segment constitute and implement the work of special legislative projects, which entail a more simple legalization of documents of electronic circulation.A question about e-services activities within different countries revealed its responses to the diversity of e-services, with 63% of the participating countries saying they started e-business services, 57.9% said they provide e-government services and 50.9% provide electronic educationservices, and 22.8% reported that they do not provide any of the electronic services to their citizens.Such acts and laws simplify operations associated with the exchange of necessary documents between government and business that contributes to good implementation of such systems in the further development of relations between thesestructures.According to Forrester Research, 38% of the Fortune 500 believe that the acquisition of modern document automation is critical for the success of their business.In accordance with the opinion of industry analysts, the benefits to businessusers when implementing the document automation sufficiently diverse. For example, according to Siemens Business Services, by using document automation. −staff productivity increased by 20-25%;−the cost of archival storage electronic documents by 80% lower compared to the cost of storage of paper archives.With the introduction of document automation acquired both tactical and strategic benefits.The object of scientific research is an electronic document management system.The subject of scientific research is a technology for modeling electronic document management systems.Purpose of work is development of technology implementation of the electronic document management system ofthe state institution of Iraq, Satisfying international standards and allowing improving the quality of the work of a public institution.
Scientific task – the development of the model of electronic document management system, Different from
the known ones according to international standards.
The realization of the goal which accomplished by solving the following particular problems:
− analysis of existing electronic document management systems and their compliance with
international standards; The development of a model of the electronic document management
system for the state institution of Iraq;
− setting up the workflow of the state institution of Iraq, Using the electronic document
management system Case.
Methods for solving scientific research problems: Methods of modeling and design of electronic document
management systems.
Scientific novelty the technology of introduction of system of electronic document circulation of the state
institutions of Iraq based on a universal model meeting the requirements of international standards.
Practical significance of the work
Application of the proposed model of the electronic document management system will improve both
qualitative and quantitative characteristics of the management system of a public institution

Theoretical values of in amorphous silicon quantum dots (1.8 – 12 nm) dielectric reduction have been
calculated. These calculations presented that the dielectric constant of amorphous silicon quantum dots is suppressed.
Also, it has been investigated the frequency dependence of the dielectric constant. The variation of the dielectric
constant with frequency is similar to the variation of polarizability and polarization. The dielectric constant is made
up of contributions from electronic, atomic, and space charge polarization. With the presented calculations, the effect
of quantum confinement was adopted, since the bandgap of nano semiconductors can be governed by the size of
amorphous silicon quantum dots.

This work is improving the performance properties of greases additives graphene concentrate. It has
been established that the addition of 1% graphene concentrate to the lubricant Solidol J contributes to an increase in its
anti-wear properties by more than 30 percent. With the enrichment of commercial grease Lithol-24 with graphene
concentrate, a decrease in the diameter of the spot of wear of the balls was determined at the plate size from 0.36 mm
to 0.30 mm. As a result of testing lubricants in rolling bearings, a decrease in the heating temperature of bearings
operating on lubricants enriched with graphene concentrate was found in comparison with commercial lubricants.

This sheet research presents the implementation of Coded Orthogonal Frequency Division
Multiplexing (COFDM) communication system encoded using Reed Solomon (RS) Coding implemented on
TMS320C6713 platform. The collaboration of MATLAB integrated development environment (IDE) and Code
Composer Studio (CCS) are adopted. The real time implementation is one of the most difficult issues of OFDM
implementation. The problem of real time implementation is the memory consumption and the processing time.
The other problem is Synchronization of OFDM receiver. Time and frequency synchronization to distinguish the
begin of the OFDM symbol. The capability of RS for encoding the error correction ability makes it the most used
error correction codes algorithm, so we use it with OFDM systems to combining them make the system has
excellent performance potentiality in multipath and fading channels. The bit error rate and the number of error bits
are calculated during each test on the system.

Filtering huge amounts of data is a very critical issue with the explosion of data over the web and
cloud storage. A need to classify and sort these data is linked to that issue to facilitate data management and
database building for various applications. Machine learning techniques are the most suitable to deal with such
big data.
One of the applications that can be implemented in machine learning is a tourist advising system that
harvests data from tourism sites and aggregates different types of data about them (humidity, temperature,
distance from user’s country, etc…) and classifies them. These data should be updated constantly, since the
system provides real-time decision based on real-time data, where they are used later on by a bagging system to
provide the user with suggested tourism sites with percentage to how suitable these sites according to the
preferences submitted in addition to some other criteria.
