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 method will be presented in the perspective to use the device as power generator or sustainer for wearable devices by using actions such as leg motion, body movements, induced vibrations or external kinetic sources but also as vibration sensor. Theoretical considerations and experimental results of output voltage, power and performance as response of localized kinetic energy are also reported demonstrating the capabilities of the proposed device.

In the last years an increasing number of attacks targeting energy consumption in computing systems have been designed and deployed. In this paper we propose a methodology that can be used to limit the effect of all types of power attacks by using the isolation properties guaranteed by virtualization systems. We describe the idea underlying our approach and we present the power consumption measurements we have carried out to validate our approach.

Network emulators are powerful tools that allow to test and characterize network equipment and protocols. The market offers several measurement solutions. The most widely adopted are software network emulators and among them surely free or open-source emulators are the most used especially in research contexts. Unfortunately, software network emulators are not distributed with technical support and certified performance information. Certified information, about the ability of these software to accurately reproduce the wanted network conditions, is very important to validate the results obtained during design activity and test campaigns that involve them. In this paper, an experimental analysis of the ability of two widely used network emulators to emulate several imposed network conditions in different test set-ups is carried out. In particular, we have focused the attention on analyzing the fidelity in the generation of both static and random packet delays under different operating conditions. Obtained results confirm that imposed conditions are not equally reproduced and particular attention has to be paid in specific situations, as very low static delay imposed conditions.

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 its orientation.

The advances in wireless low-power sensors and the increasing demand for portable healthcare monitoring systems have inspired the realization of Wireless Body Sensor Networks (WBSNs). IEEE Std. 802.15.6 defines the communication protocol for WBSN applications in terms of physical and medium access layers. The high generality and flexibility of standard requirements poses the question of how WBSN parameters, i.e. sampling frequency, node priority, superframe duration, have to be carefully set to guarantee a given accuracy level for the extraction and estimation of the biomedical information of interest. In this context, the present paper focuses on the most suitable design of network configuration by considering how the occurrence of missing packets affects the resulting quality of service. Throughout numerical simulations in Matlab, we reproduce a plausible WBSN scenario for monitoring the cardiac activity during physical exercise. The effect of missing packets on the recovered electrocardiographic (ECG) time-series at receiver side has been finally investigated, in terms of root-mean-square error and accuracy of the estimated heart rate, thus providing some criteria for choosing the most suitable network configuration.

Our daily life is characterized by countless human relationships. Every day we go to work, do shopping, partake in leisure time. At the base, there are some choices that lead us to make a series of activities; In which we interact and relate with many people. What influences the choices we make? Answering this question can be a very daunting task. However, it can help us to identify the main key elements that influence the behaviour of people. Arguably the weather conditions have a major impact in our daily decisions and events, with the more extreme weather having a stronger influence our lives. How can we tie Human behaviour to environmental conditions? Can we determine the human behaviour during a catastrophic environmental event? To answer these questions, we can query various information sources including social networks. These represent a good starting point with respect to the analysis of a human behaviour aspect. The aim of the paper is to develop a methodology in gaining an understanding to what is happening on the territory from user behaviours and vice versa. The paper will conclude with a discussion of the results generated from the application of this methodology to real cases.

The paper presents the design and implementation of an integrated wireless network that support to the multiparametric geophysical monitoring network of the Campi Flegrei volcanic area. The wireless network is equipped with a tool for real-time monitoring and fault detection. The enhancement of the transmission system with respect to the previously existing one has been realized in view of the increased need for seismic monitoring, which is a consequence of the drilling of an exploration well for scientific purposes. The goal is to increase the performance of the recently deployed transmission system in terms of availability and reliability, given the high seismic risk and hazard associated with the experiment. Thanks to the automated monitoring tool, a significant increase in the availability of the system as well as an improvement in the quality of the connection are achieved.

This work concerns the development of an efficient near-field/far-field (NF/FF) transformation technique with spherical spiral scanning suitable for an offset mounted quasi-planar antenna. Such a NF/FF transformation, relying on the nonredundant sampling representations of electromagnetic fields, requires practically the same number of NF data both when the antenna under test (AUT) is onset and offset mounted, since such a number depends only on the surface modelling the AUT. It is developed by properly applying the unified theory of spiral scannings for non-volumetric antennas, when the AUT is considered as contained in a flexible surface formed by two circular bowls with the same aperture and eventually different bending radii. Some numerical results assessing the accuracy and the robustness of the proposed technique are shown.

The current revolution of the manufacturing sector, usually referred to as Industry 4.0, is deeply modifying the traditional production paradigms. The availability of cost-effective sensing and/or computing elements as well as ad-hoc communications protocols are, in fact, making it possible to provide the whole supply chain with a global awareness about the production process. Selecting the most adequate protocol results fundamental to assure the best integration of the industrial machines with the current de-facto information framework, i.e. Internet of Things. Stemming from their past experiences on wireless communication and distributed measurement systems, the authors will provide hereinafter a proper roadmap between the different and most common communication protocols according both to the wireless operating range and industrial requirements.
