Wireless mobile communication have grown dramatically in last decades. Due to increased usage of wireless mobile networks and communications in our everyday life, the society has become extremely exposed to cyber security attacks and threats in this environment. In order to provide a basis for further in detail discussion on attacks and security mechanisms in this challenging environment, this paper...
This paper aims to consider how changes in QoS (Quality of Service) indicators affect the quality of IPTV (Internet Protocol Television) video. Degradation of QoS indicators can occur at any point in time, when the value of transfer channel function changes or if there is an appearance of additional noise. Therefore, for this purpose it is necessary to conduct a temporal analysis of the impact of...
This paper describes an embedded system for the automation of scheduling systems such as school bells, factory shift changes, military drills etc. The system consists of two parts: a remote node used for remote control and setup of the system and the real time actuator node which controls a physical object, for example, a bell system. The hardware and software structure are illustrated in detail for...
In this paper, we investigate the operation of amplify-and forward (AF) two-hop relay networks in the available of in-phase and quadrature-phase imbalance (IQI) at the relay. A close-form analysis is set up in the high signal-to-interference-plus-noise ratio (SINR) mode, where IQI effects in a top result on the SINR. From there, we can see that the time division factor, the energy conversion coefficient,...
In this paper using Artificial Neural Network (ANN) are presented forecasting results of PM10 concentrations for the city of Sarajevo. Input data of the proposed model are meteorological variables (wind speed, humidity, temperature and pressure) and pollution variable (PM10 concentration) recorded in the Federal Institute for Hydrometeorology from 2010 to 2013. The proposed model is tested on the...
The emerging and developing technology of cloud computing may be defined as an availability of scalable and easily accessible virtualised resources allowing the various paradigms. Cloud computing thus helps to reduce cost of ownership and management of virtualized resources, lowering the market entry threshold to new players and enabling provisioning of new services. Nevertheless, it is not massively...
Big Data is becoming one of the most important technology trends with a potential for a dramatic change in which organizations use information in order to improve the customer's experience and transform their own business models. Big Data as a concept is new in the world of technology and therefore requires research in technological or business sense. Management and analysis of large amount of network...
Quantum Key Distribution (QKD), based on the laws of physics rather than the computational complexity of mathematical problems, provides an information-theoretically secure way of establishing symmetrical binary keys between two geographically distant users. This paper is oriented to the practical realization of QKD public channels which are usually implemented as overlay point-to-point connections...
This paper presents challenges encountered while parallelizing an existing sequential algorithm. A breadth-first search implementation in CUDA C++ of quadratic time complexity is used. Even though BFS might seem like an easily parallelizable problem due to many independent iterations over graph vertices, there are other important aspects which need to be considered. Properties like granulation, communication...
Nowadays, the competitive market in telecommunications field which is characterized by the alterations in technology, as well as business, together with convergence and regulatory pressures is challenging for telecom operators. In order to achieve, maintain, and improve their market position, telecom operators need to redefine their business and capabilities beyond traditional services, and to address...
Smart grid can be viewed as a modern electric power grid infrastructure with enhanced reliability, flexibility and efficiency that is achieved through automated control of production and distribution of electric power, modern communications infrastructure, smart monitoring devices, and renewable energy resources. New features introduced by smart grid means that substation communication is more complex...
Electricity market designs are continuously undergoing change in an effort to improve and respond to technology, economic and policy changes. Increasing amounts of variable re-newables are a catalyst for additional market evolution. Markets work best when there is transparency between market player. The creation of smarter distribution grid started by developing an advanced metering infrastructure...
In this paper, we analyse the performance analysis for two and three time slot transmission schemes (2TS and 3TS) for two-way Amplify-and-Forward (AF) relaying networks which are developed by wireless power and data transfer, where the energy harvesting (EH) relay node helps interchange information between two nodes. We derive the throughput and the approximate expressions of outage probability of...
One of the most challenging problems in the field of digital image processing is image denoising. When processing medical images, it is of particular relevance to improve the perceived quality of images, while preserving the diagnostically relevant information. This paper investigates the capacity of a neural network framework for medical image denoising. Specifically, the performance of the proposed...
The aim of this work is to create a decision support system based on Adaptive Neuro-Fuzzy Inference System (ANFIS), which will be used for objective classification of employees in the employment process by analyzing available information about the candidates. Information about the candidates is extracted from the relevant documents on one company during the advertising for job in Information Technology...
Business process management is the process of modifying or adjusting an organization's business process in order to achieve higher productivity or lower costs. Each company or organization has a value creating process that usually involves people, machines and information. One of the main problems with such processes is that it is very difficult to predict how much of each resource is actually needed...
