An Intelligent Car Driver for safe Navigation with Fuzzy Obstacle Avoidance.
2009
In order to respond effectively to the environment uncertainties, autonomous vehicles are generally equipped with sensors. The proposed car guidance system is equipped with an intelligent controller, based on fuzzy logic, which calculates the speed and wheels orientation in order to follow a path while it is avoiding unknown obstacles. Better fluidity of driving are obtained using future-path, car dimension and car position prevision. Vehicle symmetries also speed-up and simplify the guidance system reducing the inputs and the rules numbers.
Robust and Model Predictive Control applied to DC/DC converters and Shunt Active Filters
Al giorno d'oggi, la domanda di energia elettrica incrementa giorno per giorno. La gente spesso la usa con superficialità sottovalutando quanto essa sia preziosa. Fino a qualche decennio fa, la generazione di energia elettrica era centralizzata e dipendeva dallo sfruttamento delle risorse fossili. La limitatezza delle fonti fossili, insieme agli effetti ambientali del loro sfruttamento, hanno portato la ricerca a trovare vettori energetici alternativi poco inquinanti e facilmente reperibili. Lo sviluppo e la diffusione delle fonti energetiche rinnovabili hanno sancito la fine di una rete elettrica centralizzata a favore di una nuova idea di rete elettrica di tipo distribuita che permette di…
Copy–Move Forgery Detection by Matching Triangles of Keypoints
2015
Copy-move forgery is one of the most common types of tampering for digital images. Detection methods generally use block-matching approaches, which first divide the image into overlapping blocks and then extract and compare features to find similar ones, or point-based approaches, in which relevant keypoints are extracted and matched to each other to find similar areas. In this paper, we present a very novel hybrid approach, which compares triangles rather than blocks, or single points. Interest points are extracted from the image, and objects are modeled as a set of connected triangles built onto these points. Triangles are matched according to their shapes (inner angles), their content (c…
A MOBILE ROBOT FOR TRANSPORT APPLICATIONS IN HOSPITAL DOMAIN WITH SAFE HUMAN DETECTION ALGORITHM
2009
We have been developing a MKR (Muratec Keio Robot), an autonomous omni-directional mobile transfer robot system for hospital applications. This robot has a wagon truck to transfer luggage, important specimens and other materials. This study proposes a safe obstacle collision avoidance technique that includes a human detection algorithm for omni directional mobile robots that realizes a safe movement technology. The robot can distinguish people from others obstacles with human detection algorithm. The robot evades to people more safely by considering its relative position and velocity with respect to them. Some experiments in a hospital were carried out to verify the performance of the human…
ARC FAULT DETECTION EQUIPMENT AND METHOD USING LOW FREQUENCY HARMONIC CURRENT ANALYSIS
2012
An arc fault detection circuit includes a current sensing circuit coupled to a line conductor carrying a current. The current sensing circuit operates to sense current and output data indicative of the sensed current. A processing circuit implements a frequency transform algorithm to transform the output data to frequency data in a low frequency range and with a high spectral resolution where a minimum short time observation window is concerned. The processing circuit identifies an arc fault condition on the line conductor by identifying differences in said frequency data between at least two subsequent observation windows and identifying characteristics which exceed thresholds.

SALUTE E SICUREZZA NEI LUOGHI DI LAVORO: LE RISPOSTE INTEGRATE DEGLI ORDINAMENTI STATALE E INTERSINDACALE
2020
Il saggio analizza la risposta dell’ordinamento intersindacale all’emergenza epidemiologica da Covid-19 in materia di salute e sicurezza nei luoghi di lavoro attraverso una disamina del Protocollo del 24 aprile 2020, e delle prime applicazioni contrattualcollettive. Tecnicismi a parte, lo studio sottolinea come le misure pattuite dalle parti sociali specificano ed integrano gli obblighi inderogabili e generali di legge in materia di salute e sicurezza. Infine, il saggio si interroga sulla compatibilità tra meccanismi di contact tracing e privacy all'insegna di una prospettiva multi-livello. The essay focuses on the recent measures undertaken by social partners against Covid-19 in the field …
Covid-19 e salute e sicurezza nei luoghi di lavoro: la prospettiva intersindacale
2020
Il saggio analizza la risposta dell’ordinamento intersindacale alla emergenza epidemiologica da Covid-19 in materia di salute e sicurezza nei luoghi di lavoro attraverso una disamina del Protocollo del 24 aprile 2020, e delle prime attuazioni a livello di categoria ed aziendale. Tecnicismi a parte, l’articolo sottolinea come le misure pattuite dalle parti sociali specificano ed integrano gli obblighi inderogabili e generali di legge in materia di salute e sicurezza. The essay focuses on the meausures undertaken by social partners to cope with Covid-19 having regard to health and safety in the workplace, throughout an analisis of interconfederal, national and company agreements. The article …
Somministrazione e mancata valutazione dei rischi
2019
L'articolo analizza il recente indirizzo giurisprudenziale relativo alle conseguenze sanzionatorie in caso di ricorso alla somministrazione nelle unità produttive in cui non sia stato predisposto il documento di valutazione dei rischi. The current work deals with the recent jurisprudence about the remedies in case of use of temporary employment in company units lacking of health and safety risk rating document.
PROCEDURA AMMINISTRATIVA, FUNZIONI DI GOVERNO E LIBERTÀ FONDAMENTALI NELLA "VICENDA DICIOTTI"
2019
This paper addresses some considerations on the administrative discipline of the procedure for the identification of the "place of safety" and the functional link between the Minister’s conduct and the activity actually carried out by the Minister; finally the compatibility between the ministerial nature of kidnapping (and the alleged existence of "an important public interest") with the protection of fundamental freedoms
