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.

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.

Over the last decades, the evolution of information and communication technology has joined the automation and control systems development, leading to Cyber- Physical Systems integration in industrial environments. Since complex threats targeting physical processes require advanced and interdisciplinary security approaches, classic cyber-security tools are ineffective in industrial scenarios. In this paper, we present a modular framework able to provide cyber-physical security for industrial control systems. Our Deep Detection Architecture (DDA) fills the gap between computer science and control theoretic approaches. Moreover, we present an innovative cyber-physical simulation methodology as a baseline for validation purposes.

In this paper, we address large displacements monitoring using sub-pixel offset tracking. This technique, working only with the amplitude channel, can be applied in the observation of fast movements even in scarcely temporally coherent areas. The case study concerns the Slumgullion landslide (US). It is a fast landslide, causing each year movements of several meters, thus impossible to be monitored with differential interferometry. The obtained results have been compared with those available in literature retrieved through on field measurements. This comparison confirmed the reliability of the implemented methodology.

In the Bitcoin blockchain, rewarding methods for remunerating miners participating in a pool have to meet certain requirements in order to guarantee the proper functioning of the cryptocurrency ecosystem. In particular, these allocation rules reward pool participants in proportion to their contribution in the transaction validation process. Deployed rewarding methods met fairness concerns at the expense of vulnerability to miners exploiting pools' attractiveness for deciding when to mine for a pool and when to ‘hop’ to another one resulting more attractive: a phenomenon called pool-hopping. The most used score-based methods are designed to prevent this practice, but are not completely hopping proof. In this work, we propose a methodology to analyze the pool-hopping phenomenon, focusing on the detection of pool-hoppers. Analyzing those Bitcoin transactions that pools create for rewarding its participants, it is possible to determine time epochs where miners worked. Thus, we analyze those miners that have worked intermittently for pools adopting a rewarding system which pays out for each validated block. This evaluation leads us qualifying the miners that have hopped along with their hopping behavior and financial performance.

This paper deals with the use of commercial Nanophosphate™ based Li-Ion cells at high power pulse discharge rates. An ad-hoc experimental setup allows for repeating in an automatic way a series of pulse tests on the cell with discharge currents up to 100C-rate, being C the nominal capacity of the cell. Characterization of cell ageing and State of Health (SOH) behavior during current pulses is discussed throughout the paper.

The use of multi-polarization features (intensities at the HH, VV channels and their ratio) from the X-band COSMO-Sky Med SAR images collected over an agricultural test site in Mekong Delta, Vietnam, is investigated in this study in order to develop methodology for rice monitoring. The proposed approach aims to detect rice areas and to estimate the sowing dates. The rice mapping is based on a classification of rice fields or non-rice fields and the sowing date estimation is performed with a novel procedure based on a rice training signature obtained from trends of ratio between HH and VV intensities related to rice fields.

The modelling of the magnetic losses in the core of ferrite inductors for power conversion circuits has been considered in this paper. On the basis of the Revised Generalized Steinmetz Model (RGSE) an equivalent circuital modelling has been obtained. The losses are modelled as an equivalent resistance connected in parallel to the inductor. The model has been tested under periodic triangular current waveforms.

Falls may have serious consequences in the elderly and are of great concern to the health care systems given the progressive population aging. Fall likelihood may be estimated through Gait Analysis (GA) and corrective actions might be undertaken on subjects exposed to the risk. Devices for GA, providing precise and objective measurements, are available, but either their management is complex or they are overly costly for a widespread adoption. Thus, risk assessment is often accomplished on the basis of a specialist's subjective judgment. This paper illustrates our attempt at implementing a GA platform exploiting a sensorized carpet that is already a commercial product in Europe.

The main purpose of this work is to present a tutorial description on how to design and develop an observer, which is capable of estimating the position and the orientation of a drone commanded by a controller, whose shape and structure are unknown. Starting from Newton's and Euler's laws, a mathematical model describing the dynamics of a quadcopter has first been obtained. By linearizing this model it is possible to implement a Luenberger observer and validate it with simulations in a Linux environment, thanks to the use of the Ardupilot controller and the Gazebo simulator. Finally, starting from the results obtained from the simulation, it is possible to evaluate the error made in the estimation by observer and reconstruct the trajectory traveled by the drone during the simulation.
