Il quartiere Cappuccinelli a Trapani: per un intervento di retrofit sostenibile attraverso l’uso della vegetazione

2018

La riduzione del consumo di energia primaria e delle emissioni di CO2 nell’aria sono due obiettivi chiave delle politiche internazionali, come dimostrato dagli standard sempre più restrittivi in tema di efficienza energetica degli edifici. Il settore edilizio è considerato, infatti, uno dei più importanti settori strategici al fine di raggiungere questi due obiettivi e per questa ragione le politiche energetiche a livello globale si stanno indirizzando sempre più nella promozione di strategie finalizzate alla regolamentazione della sua efficienza attraverso il progetto di edifici sostenibili. L’articolo intende dimostrare, tramite la presentazione di un caso studio, l’efficacia e la complem…

Observer-Based Stabilization of Stochastic Systems with Limited Communication

2012

Published version of an article in the journal: Mathematical Problems in Engineering. Also available from Hindawi: http://dx.doi.org/10.1155/2012/781542 Open Access This paper studies the problem of observer-based stabilization of stochastic nonlinear systems with limited communication. A communication channel exists between the output of the plant and the input of the dynamic controller, which is considered network-induced delays, data packet dropouts, and measurement quantization. A new stability criterion is derived for the stochastic nonlinear system by using the Lyapunov functional approach. Based on this, the design procedure of observer-based controller is presented,which ensures asy…

Modeling and Backstepping Control of the Electronic Throttle System

2013

Published version of an article in the journal: Mathematical Problems in Engineering. Also available from the publisher at: http://dx.doi.org/10.1155/2013/871674 Open access Electronic throttle is widely used in modern automotive engines. An electronic throttle system regulates the throttle plate angle by using a DC servo motor to adjust the inlet airflow rate of an internal combustion engine. Its application leads to improvements in vehicle drivability, fuel economy, and emissions. In this paper, by taking into account the dynamical behavior of the electronic throttle, the mechanism model is first built, and then the mechanism model is transformed into the state-space model. Based on the s…
