This article contains a detailed explanation of the research, methodology and results of different searching strategies when traversing through an unknown area. We have been challenged by the ways to simulate and evaluate the effectiveness of various approaches in order to speed up the simulation using parallel computing. The goal is to compare the...

COVID-19 takes an increasing share of everyday life and imposes the need for an exploratory data analysis executed by both, professionals and the general public. The primary focus of this paper is designing and implementing a system for processing the vast amount of case data available to obtain overall statistics for symptoms and rank them in real...

This review focuses on the analysis of non-invasive Brain-Computer Interface methods, and in particular in the state-of-the-art machine learning-based methods for Electroencephalography (EEG) acquisition. EEG as a tool can be used to detect various states concerning human health, but it can also be used to detect the human’s states such as alertnes...

The increased number of IoT devices results in continuously generated massive amounts of raw data. Parts of this data are private and highly sensitive as they reflect owner’s behavior, obligations, habits, and preferences. In this paper, we point out that flexible and comprehensive access control policies are “a must” in the IoT domain. The Semanti...

Nowadays we are witnessing the establishment of the data-driven science as a new scientific paradigm, that is opening a waste amount of new opportunities for scientific and technological advances. The data is becoming the main asset in today’s science and technology. Unfortunately, a significant amount of available and stored data is not used today...

We propose a dynamic intelligent load balancing and reactive power compensation switch plugin for power meters and a smart scalable system architecture applicable as addon on top of the existing power distribution networks. The load balancing module will improve the load balance in a network and thus decrease the power losses, whereas the distribut...

A concept guided by the ISO 37120 standard for city services and quality of life is suggested as unified framework for smart city dashboards. The slow (annual, quarterly, or monthly) ISO 37120 indicators are enhanced and complemented with more detailed and person-centric indicators that can further accelerate the transition toward smart cities. The...

Increased designers' interest in digital system design using hardware description languages has resulted in a huge data set of open source, available on the Web. Difficulties in discovering specific component introduce the need of automation in the process of search and reuse of already existing components. Despite the interface, a very important p...

Using the existing hierarchical, client-server addressing concepts and identifying the load balancing problem among phases in 3-phase systems, we propose a novel, very simple algorithm for dynamic intelligent load balancing (DILB), that decreases the power losses in a power distribution network (PDN). Our solution is easily applicable to every part...

Plug-in electrical vehicles (PEV) are capable of both grid-to-vehicle (G2V) and vehicle-to-grid (V2G) power transfer. The advantages of developing V2G include an additional revenue stream for cleaner vehicles, increased stability and reliability of the electric grid, lower electric system costs, and eventually, inexpensive storage and backup for re...

In this paper, a document collaboration platform for enterprise environments is presented. It incorporates the collaboration, security, auditing and reuse features into the document editor, as a tool that has well known interface to the end users. The platform enables template definition with annotation of the collaboration and protection units, ca...

The global warming and the frequent forest fires are the greatest evils, that is happening to the world today. They are key motivation factor in development of systems for an early prevention and detection of forest fires. In this paper, we review the general architecture of a forest fire system, present several existing systems and pilot-projects,...

A huge part of the HDL development process is spent on testing and simulation. Supporting the idea of a testbench design automation, we present a module of the HDL IP Cores system, integrated with a client-side eclipse plug-in, as an automatic testbench search engine embedded inside the designer's native programming environment. The concept is exte...

The Green IT concepts, very popular among large companies worldwide, seems to have many obstacles in some areas/communities, despite the possibility of saving money. The contribution of this paper to the scientific discussion of Green IT is based on the research done among Macedonian companies and we comment on the challenges they are faced with in...

Green IT represents a collection of strategic and tactical initiatives which directly decrease carbon dioxide emissions caused by the computer usage of companies in many different ways. The contribution of this paper to the scientific discussion of Green IT is based on the research done among Macedonian companies and it proposes practices that will...

Recently, the hardware description languages (HDL) are part of the most of hardware design processes and the HDL components are the main intellectual property (IP) of the producers of IC's. The large companies have internal databases and moreover whole code sub-versioning repositories, but however the easiness of code reuse is still quite low and t...

These days, the number of data sources an ordinary computer user works with every day is very large and continues to grow. With the increasing number of cloud services with specialized functionalities, the users are faced with the necessity to routinely perform manual actions to interchange data among different cloud and web services, in order to p...

Following the global trends and innovations in the communication and information technology, the way of communication between universities and faculties with the students, and among students themselves, became significantly different than a few years ago. The use of social networks and other forms of interactive communication for this type of commu...

Supporting the idea of the semantic web, we developed an intelligent GUI extension for the Oracle JDeveloper 11g R2.ThisGUI extension supports the basic Oracle semantic scenarios (set table space, test query with variables, call pre-written query from file and etc.) from the client side and is also a quite extensive system, thus it is very easy to...

Supporting the idea of the semantic web, we developed a Semantic Stored Procedures (SSP) programming environment for the Oracle11g database, similar to the existing ones, available for the stored procedures in the relational databases. This show-case SSP-environment supports the basic test/store/execute/remove scenarios for sem_match-queries, but i...

There are a lot of P2P computing systems or distributed GRID systems that have clients that need to be downloaded and installed on the client's computer and after that they will start with their work for the grid computation. Unlike this approach, there is another type of grid processing clients, which are based on web browsers. These Web GRID syst...

A few years ago, the System on Chip idea grew largely and ‘flooded’ the market of embedded systems. Many System on Chip designers started to write their own HDL components and made them available on the Internet. The idea of searching for a couple of pre-written cores and building your own System on Chip only by connecting them seemed time saving....
