Fog Computing as a Support for 5G Network

5G will enable new future Internet of Services (IoSs) paradigms such as\ud Anything as a Service (AaaS), where devices, terminals, machines, also smart\ud things and robots will become innovative tools that will produce and will use\ud applications, services and data. However, 5G will have to support huge mobile\ud traffic volumes, and will also have to deal with the rapid increase of new and\ud complex applications and services. On the other hand, Fog Computing, which\ud extends Cloud Computing to the edge of the network, with its service\ud orchestration mechanisms offers virtually unlimited dynamic resources for\ud computation, storage and service provision, that will overcome the constraints of\ud smart mobile devices. 5G in the fog computing environment will create\ud opportunities for companies to deploy many new real-time services that cannot be\ud delivered over current mobile and wireless networks. This paper evaluates Fog\ud Computing as a support mechanism for 5G Network in terms of latency,\ud throughput, and energy efficiency

MongoDB as solution for data warehousing in online HRM systems

With development of technology and techniques for data collection, modern business organizations are able to store large amounts of new information about customers and employees within it. In order to respond to the needs identified in the field of data warehousing and data analysis within human enterprise resource planning (ERP), business organizations increasingly opt for new ways to store the data. One of them is use of non-relational databases (NoSQL). This paper presents an information system (IS), developed for the needs of human resource management (HRM). For data warehousing IS use benefits of NoSQL MongoDB and was developed to be accessible via the Internet At this point, the authors aim to point out the potential solution in data warehousing and ERP system development. This solution can be used as the initial point for the systems further evolving, which tend to support futures that Industry 4.0 offers

Data Visualization in Business Intelligent &Analysis – Analysis of First Positioned Tools According to Gartner’s Magic Quadrant in Ability to Execute

Data Visualization tools in Business Intelligent (BI) and Analysis are very effective because they allow gaining of deeper understanding of huge amounts of data stored in databases. For this reasons many market research companies take into consideration usage of Data Visualization tools as part of their BI solutions and analyze their competitive advantage at the market as well as the benefits and disadvantages. In this paper, the Data Visualization tools that are on the top of Gartner and Forrester researches, Tableau and Qlik, are taken into consideration. They are positioned higher on the “Ability to execute” axis and\ud according to researchers’ report, are faster growing sales tools and deserve analyses in details. They are used as Visual Data Analysis (VDA) tools from theoretical and practical side and are analyzed for previous defined Key\ud Performance Indicators in order to gain deeper insights and make a comparison of their ability to execute

E-health monitoring system

Monitoring of patients’ vital parameters very often is limited to hospitals or other health care centres, which makes the process time consuming and expensive. Rapid advancement in information and communication technologies offers great opportunities for development of remote monitoring systems, which on one hand, will reduce costs and travel time, and on the other will increase health service efficiency and user satisfaction. The goal of this paper is to propose an ehealth system that allows doctors to closely monitor patients’ vital parameters, no matter where they are located. Integration of web, mobile and smart TV technology, will provide greater accessibility of patients’ data, and will improve patient – doctor communications

Modeling and evaluation of VPN laboratory exercises for Information Technology curricula

Establishment of a secure connection over Internet in industrial and commercial environments is very important. Considering that, information technology (IT) professionals are in charge for implementing the appropriate technologies. Therefore, the efficient IT security training inclusion in the university courses has the crucial role. The creation of VPN laboratory exercises for industrial Ethernet and business communication is presented in this paper. The VPN exercises are implemented on two laboratory sets for teaching VPN, the first one based on Allen-Bradley® communication equipment in combination with other hardware and software components, and the second platform based on Cisco routers. The qualitative study was conducted in order to analyze student’s experiences. Research findings indicate the importance of students experience in using learning materials and scenarios, experience in problem solving and using laboratory sets for mastering VPN technology

Artificial Bee Colony Optimization Technique for Effective Resource Allocation

Accelerating the development and deployment of advanced communication technologies and complex databases will require a comprehensive strategy integrating efforts from invention to deployment. The concurrent high-performance computing systems are composed of hundreds of thousands of computational nodes, as well as deep memory hierarchies and complex interconnect topologies. Existing high performance algorithms and tools already require courageous programming and optimization efforts to achieve high efficiency on current supercomputers. On the other hand, these efforts are platform-specific and non-portable. Since most of the existing optimization algorithms and tools are not optimized for modern computer architectures and cannot efficiently exploit massively parallel systems, one aim of this research is to identify and to analyze the general problems and modern trends in this research area. This paper investigates the efficiency of artificial bee colony optimization algorithm for effective resource allocation. Parallel version of the algorithm have been proposed based on the flat parallel programming model with message passing for communication between the computational nodes in the platform and parallel programming model with multithreading for communication between the cores inside the computational node. Parallel communications profiling is made and parallel performance parameters are evaluated on the basis of experimental results

Geometric modeling and principle of the golden section

Modeling the process is a virtual representation of the object (model). Mathematical and geometrical principles for designing a model based on the socalled golden ratio. The paper aims to present the specifics of expressing the proportions of the golden section. As the golden section studied and used by many artists and architects in the creation of their work at the end of these examples are described its use. In addition, it will be listed and examples of the golden ratio occurrence in the art

Effects of Using Databases of Educational Materials in the Education System in Macedonia

Technologies have become important part of our lives. Their inclusion in education is inevitable. The steps for introducing ICTs in education vary from country to country. Macedonia has invested with a lot of hardware and software in education. Teachers have received numerous training, some for use of ICTs. This research was aiming to determine the situation of usage of educational materials and to define recommendation for future improvements. Teachers from urban schools were interviewed with the questionnaire. Data from multiple choice questions have given quantitative results, and several open-ended questions have given qualitative information. The findings are several: only part of the interviewed teachers had experience with databases of educational materials; all teachers still\ud need capacity building activities focusing exactly on the use and benefits from databases of educational materials; technical support and upgrading of software and materials should be performed on a regular basis. Training materials for professional development of teachers on preparation and usage of databases of educational materials in Macedonian language should be developed and implemented. Subsequently, teachers will be able to design, develop, use and update educational materials in Macedonian language. Thus, application of ICT in education will have bigger positive impact
