Impact of Novel Energy Management Actions on Household Appliances for Money Savings and CO2 Emissions Reduction
2009
In order to obtain CO2 emissions reductions, energy management control actions inside apartments and detached houses have to be carried out. In this work, new control actions devoted to the reduction of electrical energy consumptions inside typical Italian apartments are proposed. These “Distributed on Site” (DoS) actions consist in employing specific control strategies to smartly exploit the hot water provided by a solar panel, the electricity generated by a photovoltaic panel and the delayed starting of appliances.

A low power and high resolution data logger for submarine seismic monitoring
2010
The design, implementation and characterization of a digital waveform recorder for ocean bottom seismic monitoring is here reported. The system is capable of synchronously acquiring, and logging on a flash memory bank, four high resolution signals. Thanks to a very careful design of the system architecture and by using robust digital signal processing techniques, two main conflicting issues have been addressed: a high dynamic range, better than 120 dB, usually obtained with high energy demanding converters, and a power consumption as low as 250 mW, hence allowing to easily increase the time of a continuous submarine monitoring session up to 3 months.
High Resolution Time Domain Reflectometry for Dielectric State Monitoring in High Voltage Cables
2017
A high resolution Time Domain Reflectometry system has been designed in order to investigate the possibility of measuring with good accuracy the dielectric properties of high voltage cables insulator materials by means of Time-of-Flight measures. The system employs a dedicated Time-To-Digital Converter in order to achieve a time resolution of 90 ps. By exploiting averaging techniques the resolution has been further increased. Experimental results showed the possibility of measuring the dielectric constant with a resolution of 0.03%.
A Two-End Traveling Wave Fault Location System for MV Cables
2019
In this paper, a new low-cost device is proposed for fault location in power distribution system. The device is part of a system that should include several units installed in couples at the two ends of medium voltage (MV) cable lines. Their low cost justifies a widespread installation of these devices, moreover other functionalities could be considered so as to enrich the potential of the system for MV cables monitoring and asset management. The system exploits a two-end traveling wave technique, low complexity, and low-cost solutions both for the analog front end as well as for the communication infrastructure. A LoRa network is indeed considered as wireless modulation technique perfectly…
An FPGA-Based Adaptive Fuzzy Coprocessor
2005
The architecture of a general purpose fuzzy logic coprocessor and its implementation on an FPGA based System on Chip is described. Thanks to its ability to support a fast dynamic reconfiguration of all its parameters, it is suitable for implementing adaptive fuzzy logic algorithms, or for the execution of different fuzzy algorithms in a time sharing fashion. The high throughput obtained using a pipelined structure and the efficient data organization allows significant increase of the computational capabilities strongly desired in applications with hard real-time constraints.
An embedded datalogger with a fast acquisition rate for in-vehicle testing and monitoring
2011
A very compact and high performance datalogger for automotive in-vehicle testing is here described. The small logger dimensions and the availability of a CAN interface allows to easily implement multiple and distributed acquisition schemes, very challenging with traditional instrumentation. High acquisition rate, up to 100 Ksps/ch, and low cost was obtained through a very accurate hardware and software design.

An Electronic Emulator of Combined Photovoltaic and Solar Thermal Systems
2010
An emulator of combined Photovoltaic and Solar Thermal (CPS) systems is presented. In order to carry out early testing on the design of such systems, a - microcontrolled based - hardware board has been designed, implemented and tested. This emulator is able run several typical daily solar irradiation patterns as a function of the seasons and a complete solar thermal and photovoltaic model that depends on a very flexible set of parameters characterizing the real CPS behaviour. By properly varying these parameters many different CPS models can easily be created and tailored to the energy performance needed for a predefined target application. Beside these functionalities, the CPS emulator is …
