STUDIO DI UNA FRIZIONE MAGNETOREOLOGICA PER AUTOVEICOLI

2013

Dopo un’accurata ricerca bibliografica sui fluidi magnetoreologici, il loro comportamento ed impiego, si è passati alla progettazione di una frizione magnetoreologica per autoveicoli. Considerando le caratteristiche di coppia trasmessa e potenza, il dispositivo è stato dimensionato tenendo presente i vincoli di ingombro del veicolo preso in esame. Sottoponendo il dispositivo ad analisi magnetostatica agli elementi finiti, si è determinato l’andamento delle linee di flusso del campo magnetico nel meato di fluido e nelle zone di maggior interesse, calcolando la coppia teoricamente trasmessa dall’innesto.È stato anche eseguito il confronto delle prestazionifra una frizione MR ed una frizione t…

Settore ING-IND/14 - Progettazione Meccanica E Costruzione Di MacchineAfter a thorough literature search on magnetorheological fluids their behavior and use it has gone to the design of a magnetorheological clutch for motor vehicles. Considering the characteristics of transmitted torque and power the device is dimensioned taking into account the constraints of space of the examined vehicle. Subjecting the device to magnetostatic finite element analysis it was determined the trend of the flow lines of the magnetic field in the gap of fluid and in areas of greater interest calculating the torque transmitted theoretically by the clutch. The performance comparison between a traditional clutch and a MR clutch was also performed pointing out that the MR clutch presents shorter response times with high energy savings. The study carried out shows that the device is well suited to a vehicle with automatic or robotic or otherwise with very short response times but requires a control system for the starting the vehicle.

Economic impact of Ice Thermal Energy Storage Systems in residential buildings in presence of double-tariffs contracts for electricity

2009

Thermal energy storage is one of the most important methods of demand-side load management, thanks to the capacity of reducing significantly the peak power demand for air conditioning in buildings. Thermal Energy Storage Systems (TESS) are indeed used for producing and storing cooling capacity during off-peak hours (in particular during night hours) to meet the following day's air conditioning requirements. The current paper presents a study on the effects of the installation of Ice TESS for cooling on the power daily profile of residential buildings, and examines the economic repercussions on the electricity billing. With reference to this second theme, the paper examines, in particular, t…

The eXtensible Dynamic Presentation Manager for content adaptation

2008

Human Computer Interaction studies deals with systems and tools that are able to improve user experience during interaction with computer. For this purpose, modern web application are expected to supply multimodal and multi-channel access, adaptivity and transcoding features. We will present in this work the eXtensible Dynamic Presentation Manager (XDPM) which is a set of innovative tools that support the eXtensible Presentation Language (XPL) in the adaptation of contents to different working contexts. The adaptation is performed according to the delivery context information which have been formalized by means of a profiler system. A profile holds information about the specific access devi…

La retribuzione nel lavoro pubblico in tempi di crisi

2019

Il saggio analizza le recenti misure di riduzione del costo del lavoro nel pubblico impiego italiano alla luce della degli orientamenti della giurisprudenza al riguardo. La crisi economica è un fattore sempre presente nelle argomentazioni dei giudici. Aumenta il tasso di litigiosità e il potere giudiziario deve valutare la legittimità del-le scelte della pubblica amministrazione e la reazione giudiziaria dei lavoratori pubblici nel tentativo di recuperare, in tutto o in parte, le quote di retribuzione perdute (o non adeguate nel corso del tempo).

Settore IUS/07 - Diritto Del LavoroThe essay analyzes recent measures to reduce the cost of labor in the public sector in the light of several judgments on the topic. The economic crisis is always present in the legal reasoning of the judges. The litigation rate increases and the judicial power must assess the legitimacy of the choices of public administration and the judicial reaction of public workers in an attempt to recover in whole or in part the remuneration quotas lost (or not adequate during the time).

LA REGISTRAZIONE OCCULTA CURATA DA UNA PERSONA PRESENTE AL COLLOQUIO

2019

Il saggio, inserito in una collettanea in tema di investigazioni atipiche alla sua seconda edizione, analizza criticamente l’ascolto “non rivelato” da parte di un soggetto presente . Le coordinate costituzionali e convenzionali consentono di mettere in evidenza l’innegabile compressione dei diritti in rilievo e una difficoltà nell’individuazione della disciplina probatoria applicabile che si ripercuote sull’utilizzabilità processuale dei risultati dell’attività di registrazione. L'analisi è condotta su un piano evolutivo che partendo dall'inquadramento sistematico mette in luce l'evoluzione normativa e giurisprudenziale, con particolare riguardo alle aree di incidenza con la disciplina del …

Il tempo del desiderio. Per Jean-Luc Nancy

2021

This essay aims to sketch the philosophical profile of Jean-Luc Nancy by analysing his last works on pandemics. In these writings the author develops a pecu- liar and pivotal care and concern for the present time, which does not actually ap- pear to be different from that produced in other works of the author’s such as “Being Singular Plural” or “The Sense of the World”. This allows us to speak of “a desire for the present” in the philosopher’s opus, which finds in the question of technology an ideal position for analysis.

A Proposal to estimate the roaming–dog Total in an urban area through a PPSWOR spatial sampling with sample size greater than two

2018

Settore SECS-S/05 - Statistica SocialeDogs roaming in urban areas constitute an issue for public order hygiene and health. Proper planning of actions for health and security control and allocation of financial funds require the knowledge of the roaming–dog–population size in a given urban area. Unfortunately a reliable statistical procedure aimed to measure such population is not available yet in literature. This paper presents a simple reproducible survey sampling procedure to estimate the number of roaming dogs in an urban area through the description of a real study carried out on a restricted area of the city of Palermo in southern Italy. A sample of areas is drawn by means of a drawn–by–drawn spatial sampling with probabilities proportional to size and without replacement (PPSWOR). As inclusion probabilities are not available in closed form they are estimated by Monte Carlo approach which is of simple implementation and permits design–based variance estimation even when first–order inclusion probabilities are unknown.
