The ATLAS level-1 trigger: Status of the system and first results from cosmic-ray data
2007
The ATLAS detector at CERN's Large Hadron Collider (LHC) will be exposed to proton-proton collisions from beams crossing at 40 MHz. At the design luminosity of 10^34 cm^-2 s^-1 there are on average 23 collisions per bunch crossing. A three-level trigger system will select potentially interesting events in order to reduce the read-out rate to about 200 Hz. The first trigger level is implemented in custom-built electronics and makes an initial fast selection based on detector data of coarse granularity. It has to reduce the rate by a factor of 10^4 to less than 100 kHz. The other two consecutive trigger levels are in software and run on PC farms. We present an overview of the first-level trig…

Effect of a Passive Tuned Mass Damper on Offshore Installation of a Wind Turbine Nacelle
2021
Abstract Although the installation of offshore wind turbines takes place in calm seas, successful mating of wind turbine components can be challenging due to the relative motions between the two mating parts. This work investigates the effect of a passive tuned mass damper on the mating processes of a nacelle for a 10-megawatt (MW) offshore wind turbine. A nacelle with lifting wires and a monopile with a mass damper are respectively modelled using the multibody formulation in the HAWC2 program. A single mass damper is tuned to target at the first natural period of the monopile and is coupled to the main program using a dynamic link library. Afterwards, numerical simulations were carried out…

Evaluating the Performances of Small Wind Turbines: A Case Study in the South of Italy
2012
AbstractAmong renewable energy resources, wind energy became more attractive in the last decade. Wind farms installations dramatically increased in areas where climatic conditions, topography and environment have allowed their development. The installation of wind turbines, usually carried out in remote areas, recently began to cover areas identified by a complex terrain such as urban and suburban zones. Although these new sites’ choices are characterized by lower productivity there is increasing interest in wind energy production in both urban and suburban area. In this work the authors have carried out an energy analysis developed from a sample of small wind turbines available on the mark…
Kalenarte 2014. L’arte del Paesaggio, ovvero del connubio tra Cultura e Natura
2014
Il saggio è dedicato all'edizione di Kalenarte del 2014, intitolata "L’arte del Paesaggio, ovvero del connubio tra Cultura e Natura". Si tratta di un progetto articolato che si inserisce nelle attività del MAACK, Museo d'arte Contemporanea all'aperto di Casacalenda (CB) in Molise, riconosciuto come uno dei parchi d'arte contemporanea più importanti d'Italia, e consiste nello svolgimento delle residenze d'artista di Nelida Mendoza e Baldo Diodato, esponenti di rilievo della scena internazionale dell'arte contemporanea e nell'installazione delle opere site specific ideate d'accordo con la comunità locale. The essay is dedicated to the 2014 edition of Kalenarte, entitled "The art of the landsc…
Yumiko Kimura, Jun Sato. Universi geometrici
2016
The catalogue is dedicated to the artistic research of Yumiko Kimura (Tokyo, 1961) and Jun Sato (Tokyo, 1947). The catalogue was made on the occasion of the exhibition "Geometric Universes", which presented a selection of works by the Japanese artist in the Valley of the Temples in Agrigento and then at the FAM gallery with the patronage of the Museum of Geometric and MADI Art in Dallas and the inclusion in the official celebrations of the 150th anniversary of relations between Japan and Italy.
Yumiko Kimura. Invenzione e geometria
2016
Il saggio prende in esame la ricerca artistica di Yumiko Kimura (Tokyo, 1961), artista specializzata in sculture in vetro che coniugano arte geometrica e ricerca della luce. Il contributo è stato realizzato in occasione della mostra "Universi geometrici", che ha presentato una selezione di opere dell'artista giapponese all’interno della Valle dei Templi di Agrigento e poi alla FAM gallery con il patrocinio del Museum of Geometric and MADI Art di Dallas e l'inserimento nelle celebrazioni ufficiali del 150° anniversario delle relazioni tra Giappone e Italia. The essay examines the artistic research of Yumiko Kimura (Tokyo, 1961), an artist specializing in glass sculptures that combine geometr…
