Conference proceedings front matter may contain various advertisements, welcome messages, committee or program information, and other miscellaneous conference information. This may in some cases also include the cover art, table of contents, copyright statements, title-page or half title-pages, blank pages, venue maps or other general information relating to the conference that was part of the original...
The objective of the study is to develop an efficient travel management model to generate a smart transportation corridor system to mitigate congestion which will prevent, or minimize traffic delays on urban freeways. Based on a first order partial differentiation (PDE) method via a “continuum” approach this study develops a mathematical model which will capture the behavior traffic flow during the...
ZnO tetrapods were synthesized by an “environmentally green” microwave evaporation of Zn powder in air atmosphere, without any use of organic solvents or precursors. The tetrapods were characterized by X-ray diffractometry and Field Emission-Scanning Electron Microscopy. The ZnO powder was then deposited onto a commercial alumina substrate with interdigitated platinum electrodes and the sensitivity...
In this paper, we present measurements of the optimum signal-to-noise ratio distribution recorded by RFID reader based on software radio. The measurements are conducted in an indoor environment while maintaining an RFID setup that does not deteriorate the tag responsiveness. The analysis shows that, although non-linear in nature, the RFID system signal-to-noise can be characterized through the scale...
3D-printing technology promises high added value in many scientific contexts, including that of new materials for electromagnetics. The joint use with Radio Frequency Identification (RFID) technology is very appealing for designing new RFID-based smart devices while maintaining cost-effectiveness. In this work a T-Resonator structure for the dielectric characterization of substrates, including 3D-printed...
Machine learning is a useful method to assess biomedical data. However, due to the complexity of these data, it is important to rely on a robust methodology. Predictions with machine learning are not only an add-on to statistical analysis but are a real process of discovering and establishing clinical validity of the diagnostic techniques. This paper describes a machine learning approach to predict...
In this work we present an IC architecture of RF energy harvesting for wireless sensors networks. By analyzing a probabilistic approach used for modeling the possible amount of Global System for Mobile Communication (GSM) energy that could be harvested, an IC system with a 0.18μm CMOS SMIC technology has been designed and optimized at 90 and 900 MHz. so to take advantage of the GSM and FM radio radiated...
This work presents the design and implementation of a low-complexity beam steering polar transceiver based on a revised DDS-PLL phase shifter architecture. The proposed modulator-less topology targets narrowband communications for enhanced Internet-of-Things systems, and has been prototyped using an FPGA evaluation board and a custom PCB with four PLLs centered at 2.453-GHz. Measured system performance...
In automatic and image processing based wildfire smoke detection various spatial and temporal procedures are used to detect certain wildfire features. The final step is usually the classification procedure that finally decides if some detected phenomena represents wildfire smoke or not. In classification procedure various classifiers can be used, but as the system has to work in real time and usually...
Current manually-operated SOS systems used in Rallying are ineffective when driver and co-driver cannot push the SOS button due to loss of consciousness after the impact. The SafeRally service proposes a low-cost pilot monitoring system, to associate with existing tracking systems, able to automatically notify a serious accident, when both the driver and the co-driver cannot request help by themselves...
This paper presents a visual comfort considered light control method for energy savings in open-plan office and investigates its performance. Simulation and pilot testing results show that more than 60% energy savings could be achieved while providing recommended visual comfort level for each user. Since the proposed algorithm saves energy significantly compared to the previous light control policies...
Social media are increasingly used with different purposes, ranging from attempts to reach wider audiences, to attract different publics, to propose alternative means for interaction with citizens and/or other stakeholders. Apparently, there is an immense list of possibilities and there is potential to explore social media as one of the vehicles for providing smart governance for smart cities taking...
Since its definition, RPL (the IPv6 Routing Protocol for Low-Power and Lossy Networks) has been emerging as the standard protocol for routing in Internet of Things (IoT) solutions. RPL is a proactive routing protocol that performs the process of route creation based on Objective Functions (OFs). The OFs are responsible for defining rules and constraints to select the best paths considering different...
We present a method for estimating overheating of a partially covered solar cell module by use of short-circuit current measurement combined with infrared thermography. The resulting analysis allows for predictive calculation of over-heating and thus prevention of damage to the solar cell module due to partial shadow induced overheating.
The need for fast, reliable and sustainable means of communication is on the rise. Beacons are all set to revolutionize the industry with its immense potential and the ability to be deployed almost anywhere to offer an enhanced user experience. In this paper, we design and validate a context aware content delivery system using a Raspberry Pi which plays the role of a beacon. A local database has been...
Parkinson's disease is a common neurodegenerative disorder causing several motor symptoms. Gait disorders such as festination and freezing of gait are important clinical problems, since, despite their high impact on patients' quality of life, they are poorly understood and counteracted phenomena due to their episodic nature, heterogeneous manifestation, and drug resistance. Automatic and objective...
