This paper presents an obstacle detection system able to permit the visually impaired user to get information on the surrounding complex environment. The system also allows setting an active mobile connection with the distant assistant guide. A low-cost ultrasound microcontroller based system, capable of detecting grounded or raised obstacles up to a few meters in front of the subject, is proposed...
This paper presents an algorithm for Distributed Generation (DG) allocation planning, using fuzzy set theory and fuzzy multi criteria decision making based on the Bellman-Zadeh method. The proposed model considers power losses and investment deferral values on one side (goals) and line currents, node voltages and short circuit power values on the other (constraints). The objective of this work is...
One of the recent advances in ceramic tile industrial production is the introduction of ink-jet printers. Ink-jet printers are used for face texture printing in the biscuit tile production stage. This enables production of various ceramic tiles. Different textures and images can be used as the face of the tile. Because of this advance in automatic tile production, it is possible to introduce new methods...
One of the most important components for proper functioning of cities is the mobility. As the paper focuses on transportation, the use of Intelligent Transportation Systems is crucial to enable modern smart cities solutions, both in cargo as well as passenger transport. This paper presents various problems of the typical city with regards to transport and mobility. Some problems are already partly...
This paper deals with the Internet of Things solutions and value chain related to the Smart City domain. Characterization of the IoT services and applications including connectivity requirements is proposed and illustrated with two case studies, on smart parking and air quality monitoring based on urban crowd sensing. Regulatory issues, as well as the role of the national regulatory authority for...
New Renewable Energy sources are changing the way the Electric Grid is conceived: new challenges are given to Distribution Network Operators (DNOs) and to Transmission Systems Operators (TSOs). These challenges regards business models adopted and reliability, efficiency and controllability of the system. In this new framework, it is important to give to Decision Makers tools able to help them in facing...
The multiobjective allocation optimization of single tuned passive power filters for decreasing the power losses and harmonic mitigation in distribution networks is presented in the paper. The Pareto definition of the multiobjective problems is used in the paper. The two objectives problem consists of the two technical objective functions, the real power losses and the total harmonic distortion, is...
Data stored in the database mostly represent current valid state. Nowadays, complex information systems require data evolution management, state monitoring over the time. Temporal definition has been proposed, which is, however, still based on conventional paradigm. Therefore, non-current values are difficult to obtain, manage and evaluate. In this paper, several temporal evolution streams are proposed...
This paper proposes a real-time Audio and Video Artifacts Detection Tool (AVADT), solution that wraps implemented artifacts detection methods for most important and common audio and video artifacts. It can also be used for evaluation of different modules and functions of device under testing (e.g. encoder, decoder). AVADT can operate in two modes: offline mode for evaluation of existing, locally stored...
Paper derives a procedure of identifying induction machine variable inductance values. Parameter identification is done from measurements during no-load direct start acceleration. Genetic algorithm is used for parameter identification. It is used to minimise least squares difference between calculated and measured data by selecting parameters of induction motor model. Variable inductance is identified...
Together with the rapidly increasing trends of smart systems, there is a clear need for integration tools of different technologies spanning from individual user to smart city conception. With 40% of total world energy consumption, building systems are put in the central focus of the area. The paper introduces modular technology integration strategy based on model predictive control and focuses on...
In this paper, we briefly introduce the social sensing and sentiment analysis paradigms. The first one regards the general framework in which information coming from social media, and in particular from On Line Social Networks (OSNs), may be used for mining useful knowledge to be exploited in several real-world applications. Indeed, all the elements that people share on OSNs (texts, links, positions,...
