Owing to the exponential expansion in the data size, fast and efficient systems of analysis areextremely needed. The traditional algorithms of machine learning face the challenge of learning bottlenecks suchas; human participation, time, and the accuracy of prediction. But, the efficient and fast methods of dynamiclearning offer considerable advantages like lower human participation, rapid algorithms of learning, and easinessimplementation. This review paper presents the researches with a brief display for recently existing works in big dataanalytics and the effective algorithms of machine learning, furthermore, the issues of resources allocation in big data

The world is witnessing a marked and rapid change in the use of the Internet in all areas of life
and this is a natural development. Because the existence of the web has swelled and increased and became a lot in
various magazines depend on it and greatly. Our topic today is about Internet applications in libraries and information
centers. How has library performance developed in general? What are the challenges facing librarians? What is the
benefit of the students and researchers?
Thanks to the presence of the Internet there has been a great revolution in the performance of libraries and traditional
processes and developed many of them, for example, reference services, document delivery, resource sharing, and
others.
Librarians and staff in information centers face significant challenges in developing their Web site. And this returned
to all those who come to the library benefit, where there is a schedule of dates and official holidays, planning
of buildings within the library, information center for easy access to the destination and organization of different
memberships in different categories, circulation and acquisition, and easy to announce the activities of various
periodicals and seminars and know all the details and special rules. This research tries to introduce the impact of
the technology on the libraries in terms of librarian and library visitors and the resources in the libraries

Let X be a T -module, T is a commutative ring with identity and K be a proper submodule of X. In this
paper we introduce the concepts of 2-visible submodules and fully 2-visible modules as a generalizations of visible
submodules and fully visible modules resp., where K is said to be 2-visible whenever K=I2 K for every nonzero
ideal I of T and AT -module X is called fully 2-visible if for any proper submodule of it is 2-visible.Study some of
the properties of these concepts also discuss the relationship 2-visible submodules and fully 2-visible modules with
2-pure submoules and other related submodules and modules resp. are given

ontext:The way public organizations produce, acquire, use, and commercialize software ischanging as a result of open source software (OSS). Because of the numerous benefits provided by open sourcesoftware, public organizations began to use it to meet their demands. As a result, governments implement variousmeasures to encourage and facilitate OSS use. A variety of factors continue to influence the choice to implementOSS, which can have a positive or negative impact on the adoption process.Objective:The study’s purpose is to explore the most critical factors that may influence the open source softwareadoption process, which are drawn from chosen case studies from various domains in public organizations. Based ontheir findings, the authors produced a guideline to tell prospective adopters about the most crucial factors that theymay confront during the adoption process.Method:Authors chose a handful of publications that address three public domains: healthcare, municipalgovernment, and higher learning institutions. We looked for articles based on various criteria, beginning with theirrelevance to open source software adoption in general and, more specifically, in the public sector. We also screenedthe papers based on whether they were written in simple English or if they were written in another language.Results:According to the findings, government and top management support, reliability, security, availability, andcost ownership are the most influential elements that contributed to the adoption process’s success. Lacking ofin-house development, connectivity, quality, computing resources, and expertise were identified as barriers to theadoption of open source software in specific sectors.
