The Hydrogen Readiness Program Workshop with Marco Quaranta, IVECO Trucks Australia
Following a series of online forums as part of the Victorian Hydrogen Hub's Hydrogen Readiness Program, the half-day mobility workshop 'Exploring the pathway to net-zero vehicles' was held at Crown in Melbourne. This video contains an interview following the workshop with IVECO Trucks Australia's Strategic Projects and Institutional Relations Manager, Marco Quaranta
Riga. Gianni Celati
Gianni Celati, a cui “Riga” dedica un nuovo numero dopo quello del 2008, è oggi uno degli scrittori italiani più importanti e significativi. Questo volume raccoglie suoi testi narrativi e saggistici, interviste e conversazioni radiofoniche, parti dell’inedito Taccuino Siciliano del 1984, brani delle lezioni bolognesi al DAMS dedicate alla letteratura americana, testi sul cinema e la letteratura, su James Joyce, da lui tradotto, su Giacomo Leopardi e Alberto Giacometti, e poi sulle idee di spazio e di paesaggio. Seguono una scelta di recensioni e commenti alla sua opera, dal 1971 al 2008, da Calvino a Manganelli, da Luigi Ghirri a Stefano Bartezzaghi. Completano il volume un Album di oltre quaranta fotografie, dagli anni Settanta al Duemila, e una serie di saggi scritti per l’occasione che approfondiscono l’opera di uno dei maestri della letteratura del secondo Novecento e oltre
MABS validation through repeated execution and data mining analysis
Agent Based Modelling is the most interesting and advanced approach for simulating a complex system: in a social context, the single parts and the whole are often very hard to describe in detail. Besides, there are agent based formalisms which allow to study the emergency of social behaviour with the creation and study of models, known as artificial societies. Thanks to the ever increasing computational power, it's been possible to use such models to create software, based on intelligent agents, which aggregate behaviour is complex and difficult to predict, and can be used in open and distributed systems. Data mining is born in the last decades in order to help users in finding useful knowledge from the otherwise overwhelming amount of data available nowadays from the web and the data collected every day by companies. Data Mining techniques can therefore be the keystone to reveal non-trivial knowledge expressed by the initial assumption used to build the micro-level of the model and the structure of the society of agents that emerged from the simulation
A Generalised Beam Formulation for the Dynamic Analysis of Camber-Morphing Helicopter Blades
Morphing structures can be used for aircraft to modify the shape of lifting surfaces during the different phases of operations. The analysis of peculiar topologies often employed in this type of structure is very complex and requires the development of large, computationally intensive three-dimensional finite element models, to be used for static and dynamic analyses. However, the structures of rotorcraft blade behave like prismatic beams. So a tailored semi-analytical formulation can be developed, by assuming that it is possible to characterize appropriately the behavior of the blade section. This article shows how it is possible to exploit the same semi-analytical approach also for the analysis of the behavior of morphing structure that are designed to allow a chordwise variation of the curvature of the lifting surfaces
Preparation and characterisation of Li-doped ZnO films
ZnO:Li films have been prepared by radio frequency (rf) diode sputtering using a Li-doped ZnO target. The film depositions were performed in pure Ar or in 28% O2/Ar sputtering gas. For comparison undoped ZnO films were also prepared. Structural, electrical, and optical measurements have been performed on films prepared under different deposition conditions and the results related with Li content and O/Zn ratio obtained by nuclear reaction and Rutherford backscattering measurements, respectively. The Li doping has not changed the films c-axis preferential orientation typical of the undoped films, but it introduces a crystallite order change. As is expected by deposition of doped oxides the sputtering gas mixture is the main parameter controlling the dopant concentration. Moreover, the oxygen presence in gas mixture has also been found to play an important role in controlling the optical properties of the film. The change in lithium concentration does not affect the electrical resistivity if the deposition parameter values have been selected in order to produce undoped zinc oxide films with a high electrical resistivity
