Smart objects are present in our cities everywhere, thus it is becoming more and more necessary to have a connection platform, not only capable to make those objects talk with each other, but to present the results of their functions also to the citizens/users. Objective of this paper is the definition and development of a model that represents a connection and interaction layer between smart objects...
In this paper two methods for blind source separation of nonstationary signals, such as electroencephalogram output, applied to time frequency distributions are compared through implementation in a virtual instrument. Both methods are based on image processing approaches, but adopt different strategies for solving the blind source separation problem: the first method is based on a data clustering...
Buildings energy efficiency plays a key role in terms of reducing energy consumption and improving the internal comfort. For this purpose, European standards regulate the use of different insulation systems, applied to the internal or external building envelope. However, different studies demonstrate that considerable thicknesses of insulation layers are inappropriate in our Mediterranean climates...
This paper presents a novel solution for noninvasive real-time heart rate monitoring by the Microsoft device Kinect™ version 2.0. In this paper, it is firstly evaluated the state of the art concerning the solutions for non-invasive detection of vital signs and secondly it is presented the implementation and the tests of a novel methodology for evaluating the heart rhythm by a non-invasive monitoring...
Sports and recreational activities provide an interesting domain of research that includes several of the critical challenges for next generation of services. The adoption of emerging Internet of Things technologies into the field of sport could significantly improve the sport experience and also the safety level of team sports. To this purpose, this paper presents a novel Sport System based on the...
An essential task in devising photovoltaic power plant energy production capacities is based on the evaluation of a PV module thermal behavior from typical meteorological conditions in a given place. Multi-layer models (MLMs) allow to evaluate precisely the PV cell temperatures and to calculate both front and back layer temperatures through at least a 3 temperatures multi-layer models (3T-MLMs). Front...
The paper describes design and features of novel semi-autonomous floor scrubber add-on module, used for cleaning large indoor and outdoor tile/marbles spaces found in modern (smart) cities. Module is designed in such a manner that it can be easily added to and removed from scrubber machine and that additional sensors and capabilities can be introduced (modular design). In the paper localization capabilities...
The research presents results of analysis of 36 ferry and passenger routes on the Croatian Adriatic shore, with sail time up to 60 minutes. 19 of the routes representing 41.5% of daily mileage in the high season have been found suitable. Those lines carried 81.1% of all passengers and 87.4% of vehicles in the domestic sea transport in 2015. Detailed analysis of requirements for electrification has...
It is expected that the fifth generation (5G) of mobile networks will be standardized in 2020. For this new generation, there are several new performance requirements in addition to higher data rates. E-health and the Internet of Things (IoT) are two important applications that define the new requirements. In this paper, we discuss several technological trends in wireless communications towards 5G...
In this work SPARTACUS a novel Passive RFID augmented device useful to be adopted in challenging IoT contexts like the building automation is presented. While being completely passive, the novel RFID tag conjugates identification, sensing, local computing, and actuation control and enables a proactive communication with any standard RFID reader. Thanks to a specific electromagnetic design and exploiting...
This work presents a performance evaluation study of LOADng routing protocol in Internet of Things (IoT) applications. LOADng is a simplified light version of AODV developed taking into account the limited resources of IoT devices. Initially created in 2011, LOADng emerges as an alternative to the standard RPL protocol. The use of LOADng is justified once several studies has exposed the drawbacks...
Multichannel electroencephalogram (EEG) signals are known to be highly non-stationary and often multi-component. A new method for its complexity, in terms of number of signal components extracted from its time-frequency distributions, has been proposed in this paper. Exploiting its spectral energy variation with time, the joint time-frequency distribution approach was upgraded by the modification...
One of the important elements of successful parenting is care for children's safety, which includes parental knowledge about children's whereabouts, especially when a child has complex communication needs. In this context smartwatch may become a new aid not only for children but for all persons with complex communication needs, primary due to location and communication functions which can be efficiently...
Currently, the fast rate of population growth in urban areas are putting a big pressure in services supply. In order to fulfil citizens' demands, the cities' operations need to be intelligently optimized. All around the world cities are implementing smart cities initiatives to address this challenge. The development of smart initiatives implies the adoption of solutions that heavily rely on Information...
