Deep Convolutional Neural Networks (DCNNs) achieve state of the art results compared to classic machine learning in many applications that need recognition, identification and classification. An ever-increasing embedded deployment of DCNNs inference engines thus supporting the intelligence close to the sensor paradigm has been observed, overcoming limitations of cloud-based computing as bandwidth requirements, security, privacy, scalability, and responsiveness. However, increasing the robustness and accuracy of DCNNs comes at the price of increased computational cost. As result, implementing CNNs on embedded devices with real-time constraints is a challenge if the lowest power consumption shall be achieved. A solution to the challenge is to take advantage of the intra-device massive fine grain parallelism offered by these systems and benefit from the extensive concurrency exhibited by DCNN processing pipelines. The trick is to divide intensive tasks into smaller, weakly interacting batches subject to parallel processing. Referred to that, this paper has mainly two goals: 1) describe the implementation of a state-of-art technique to map DCNN most intensive tasks (dominated by multiply-and-accumulate ops) onto Orlando SoC, an ultra-low power heterogeneous multi cores developed by STMicroelectronics; 2) integrate the proposed implementation on a toolchain that allows deep learning developers to deploy DCNNs on low-power applications.

Working collaboratively is no longer an issue but a reality, what matters today is how to implement collaboration so that it is as successful as possible. It is therefore necessary to consider the criteria to be taken into account to promote its effectiveness. As part of our work, we are interested in taking into account the collaboration context for this purpose and the role that contact can take in this context. We wondered about its definition, representation and exploitation. The latter must be able to be done at different stages of collaboration: before, during and after. In this article, we present the collaboration context model that we have established and show why and how it can be used to establish successful collaboration.

Radio over Fiber (RoF) is one of the main technologies for the next-generation access networks due to its immunity to electromagnetic interference, low latency, low power consumption and high transmission capacity. RoF enables the processing of several radio frequency (RF) signals in a centralized location, reducing both capital expenditures (CAPEX) and operating expenditures (OPEX). This paper describes a testbed of Internet-of-Things (IoT) for environmental monitoring based on RoF that is under development in the framework of the H2020 FUTEBOL project. Moreover, we assess the impact of RoF on network performance by using a new methodology oriented to real environments.

The Internet of Things is an inter-networking of physical devices that communicate with each other through the Internet. The technological progress of the last few decades and more efficient wireless protocols led to an exponential growth of devices connected with an increasing amount of data exchanged across the globe. The birth of the IoT caused significant changes in different sectors, among which e-Health, involving big innovations in medical care, prevention and remote diagnosis. The goal of our project is to plan and implement an IoT node to collect clinical data and to detect atrial fibrillation through the analysis of electrocardiogram. We chose to focus on this particular arrhythmia because it represents one of the most common heart diseases. Additionally, it is often asymptomatic and associated with more dangerous illnesses. The device validation has been realized on a sample of patients affected by atrial fibrillation and other heart diseases, in order to evaluate the reliability of the obtained data and the efficiency of the algorithm. Finally, we have analyzed the advantages and limitations of the device, introducing potential future adjustments that could improve its functionality.

The media has brought to the attention of the general public the issue of subjects claiming titles (e.g. academic degrees) which they have not achieved. Verifying these identity claims can be a cumbersome task. In this paper we show how identity claims can be supported through a permissioned blockchain. Although our approach can be applied to multiple contexts, we focus on the scenario where educational institutions provide graduation titles to subjects. The subjects can then demonstrate the possession of the given titles through transactions in the blockchain. We validate the feasibility of our approach through an implementation, named Scholarium, based on MultiChain, and provide a security analysis of the proposed system.

In this paper the partial waveforms technique is applied to model electric vehicles battery chargers for harmonic penetration studies. After some recalls on partial waveforms technique, the EV battery charger based on the boost architecture is briefly described. The results of numerical examples show the ability of the developed time domain model to accurately assess the harmonic emission in the ac supply network.

This paper deals with the control of aggregated domestic thermostatic loads, as refrigerators and water heaters, in order to provide an effective support to the primary frequency regulation, without compromising the secondary frequency regulation and the customer comfort. The analyzed control strategies are those defined by ENTSO-E and three alternative strategies proposed in the present paper. The dynamic models of the aggregated loads are implemented and tested in the MATLAB/Simulink™ platform. Several simulations of a model of the Sardinian electrical grid are performed to evaluate the impact of the considered control strategies on the provision of frequency regulation services.

To consolidate the new 5G paradigm, many aspects correlated to the business model, societal impacts, must be analysed. The 5G Italian experience coordinated by “Ministry of Economic Development” (MISE Trial) has the target to create and enforce a 5G ecosystem development in Italy involving different public and private actors, industries, research centers and universities, like in the 5G PPP initiative. The potential synergies to improve the global 5G ecosystem in Italy are analyzed and the selected use cases are introduced to describe how to create the “5G road” in Italy.

This paper deals with photovoltaic (PV) systems with operating voltage increased over the value 1500 V in DC, which represents the limit of the current solutions and the actual standard for the PV plant at utility-scale level. The increase of the DC voltage is aimed at reducing the cable energy losses, the number of components and to optimise the layout of the plants, increasing the competitiveness of Medium Voltage PV (MVPV) solutions with rated powers of hundreds of megawatt. The analysis carried out has identified the possible solutions to adopt in order to reach this target and has remarked that today the International Standards are not covering all the aspects of the technical solutions to be introduced in a MVPV plant. This paper indicates the key issues to be addressed by new Standards on some components in order to enable the deployment of MVPV solutions. Finally, the characteristics of an installation at 1500 V DC and some results of tests carried out on the isolation system of a 1500 V PV plant are discussed.
