The paper proposes a customized frequency domain energy detection spectrum sensing scheme. It is needed to fulfill requirements provided by the IEEE 802.22 standard, aimed at extending Internet services to Television White Space frequencies. It provides a detection scheme allowing to achieve strict sensitivity required by the protocol either in sensing time or in detection capabilities. In particular,...
A near-field/far-field transformation for circular aperture antennas, formulated as a linear inverse problem, is here proposed. The approach takes into account for the a-priori information about the radiating and geometrical characteristics of the antennas under test, by representing the aperture field with Circular Prolate Spheroidal Wave functions.
Participation of electromagnetic compatibility testing laboratories in proficiency tests is a recommended practice for the purpose of assuring the quality of test results. Participation to proficiency tests is mandatory for laboratories accredited to ISO/IEC 17025 [1]. However a proficiency test can be successfully organized and completed only if the measurement method in the scope of the proficiency...
The idea of Industry 4.0 includes the concept of Industrial Internet of Things (IIoT) that is the possibility for industrial devices to have Internet connection and share data. Huge amount of data are stored and analyzed in the Cloud to extract meaningful information to be sold as "services". Today, many Industry 4.0 scenarios do not require a short latency between data collection and output...
In this paper, a technique for accurate estimation of the moment of magnetic dipole is proposed. The achievable accuracy is investigated, as a function of measurement noise affecting estimation of magnetic field cartesian components. The proposed technique is validated both via simulations and experimentally.
Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
Streaming media applications generate a sizable part of network traffic and represent a significant proportion of network providers' income. The commitment to user satisfaction can be summarized by different concepts, content providers emphasizing quality of experience (QoE), whereas network providers are more focused on quality of service (QoS). Measuring QoS parameters, and understanding the relationship...
Mobile Broadband (MBB) access networks are becoming more and more used worldwide, and the devices adopted to access them are increasing in number and complexity (smart-phones, mobile hotspots, vehicular infotainment systems). The highly dynamic nature of such scenarios calls for continuous monitoring and measurement of the network. To this aim, the Available Bandwidth is a performance metric of the...
In this paper we present characterization of a soft, flexible and stretchable piezoelectric transducer towards its use as mechanical energy scavenger. In particular here we address the mechanical to electrical conversion process, an intense characterization procedure has been performed in order to evaluate the performance of a conformable piezoelectric foil. The proposed transducer and the measurement...
This work aims to present the results of the first phase of crowdfunding campaign devised to involve general public in the development of a portable device for air quality monitoring and the associated infrastructure. A portable device based on an array of electrochemical sensors has been developed and calibrated in lab in order to build detailed maps of personal exposure to air pollutants with the...
An effective remote monitoring of elderly people in telehealth applications requires their everyday activities not to be affected by the monitoring. In this regard, a possible strategy is to make sure that the components (i.e. sensor and antenna) necessary to carry out such monitoring are seamlessly integrated within the elderly's daily routine. Starting from these considerations, the present paper...
This paper presents a measurement system for UHF-RFID tag detection employing leaky coaxial cable as distributed reader antenna. The proposed system is characterized through an experimental analysis in terms of S-parameters. Then the leaky feeder is employed in a measurement setup with commercial UHF-RFID reader. Measurement results show the leaky feeder capability to detect tags independently on...
Museum environmental monitoring is an important issue for the artifact conservation. Many solutions have been proposed to tackle this problem, but the museum constraints prevent an easy application in several cases, especially if the monitoring has to be performed in museums where an environmental control system has been already installed. This paper describes a simple though powerful solution, which...
Brain-Computer Interface (BCI) is an innovative communication technique mainly used in biomedical applications for assisting devices. In this context, main aim is help people with severe disabilities restore the movement ability, or replace lost motor function controlling external devices, or communicate with other people leading them to become more self-sufficient. The connection between BCI and...
Monitoring system designed for biological and marine environment observation are equipped with different types of sensors related to different disciplines. For each sensor integrated in the system it is necessary to develop a driver (software/firmware) specific to its operation. This kind of approach limits the system flexibility because the addition of a new sensor involves the update of the entire...
A novel technique based on the Field Mapping Algorithm (FMA) is proposed to gauge reflector surface smoothness from near-field reflector measurements. The proposed method provides exact information of the antenna surface with much less computation time compared with other available techniques. A few examples are given to illustrate the advantages of the new surface-analysis technique.
