Le città visibili / Visible cities
No full textFrancesca Belloni intervista Vittorio Magnago Lampugnani, storico e teorico dell'architettura, professore emerito ETH Zurigo.
Il numero monografico della rivista - Le scuole di architettura nel teatro del mondo / Schools of architecture on the world stage - curato da Francesca Belloni ed Edoardo Colonna di Paliano, tratta il tema dell'insegnamento dell'architettura, individuando alcuni ambiti geografici di riferimento. In un momento in cui la figura dell’architetto è in continua trasformazione e allo stesso tempo in profonda crisi, tanto da far emergere da parte di alcuni l’interrogativo sulla sua stessa sopravvivenza, almeno nelle forme tradizionali fino a oggi
conosciute, la rivista “Architettura Civile” si propone di riflettere sull’insegnamento dell’architettura.
All'interno della sezione dedicata alla "Scena svizzera e tedesca / The Swiss and German scene" l'intervista a Vittorio Magnago Lampugnani pone l'accento sulla visione dell'architettura in ambito svizzero-tedesco e la tradizione della progettazione urbana nel contesto dell'architettura contemporanea

All'interno della sezione dedicata alla "Scena svizzera e tedesca / The Swiss and German scene" l'intervista a Quintus Miller pone l'accento sulla visione dell'architettura in ambito svizzero-tedesco, sulla tradizione dell'insegnamento di Aldo Rossi al Politecnico di Zurigo, sul rapporto tra memoria e progetto di architettura e sugli strumenti impiegati nell'insegnamento del progetto in uno degli atelier dell'Accademia di architettura di Mendrisio - Università della Svizzera italiana
Ice skating
No full textWhat we are proposing in this chapter is an overview of the ice skating. We are now not considering the figurative ice skating, but only the ice speed-skating. Furthermore, only few hints will be provided about the outdoor skating, focusing then on the indoor competitions. After an historical reconstruction of the origins of this sport, the analysis will be divided into two main blocks: the dynamical model and the aerodynamic analysis of a speed skater (both numerical and experimental). Few notes about the track will be discussed along the chapter
Analysing the Effect of Chassis Torsional Flexibility on the Rollover Threshold of a Multi-Purpose Agricultural Vehicle
No full textMulti-purpose agricultural tractors are vehicles that are usually involved in different operations, including road maintenance in small villages and cultivation of small agricultural plots, particularly in mountainous areas. These vehicles typically feature narrow tracks to enhance manoeuvrability, making rollover stability a critical consideration in operational settings. This characteristic arises from the interplay between the suspension and vehicle chassis. This paper introduces a numerical multi-body model designed to replicate the dynamics of a multi-purpose tractor with a torsional chassis. Model parameters were derived through experimental measurements conducted on an actual vehicle. Static measurements were performed to assess tire and suspension stiffness while tilting tests were performed to establish the static rollover limit of the vehicle. Dynamic tests conducted on a four-post test rig characterised the vehicle’s dynamics. The validated model was utilised to explore the vehicle’s stability by reproducing the static rollover tests and simulating the vehicle’s performance under working conditions on a banked road. The vehicle rollover stability was studied by performing a sensitivity analysis that considered both chassis torsional stiffness and suspension stiffness under different loading conditions. The results indicate a trade-off between frame and suspension stiffnesses that enhances overall vehicle stabilit

No full textWith the increasing emphasis on environmental sustainability, the electrification of urban public bus fleets has gained significant attention. Understanding the factors influencing the energy consumption of battery-electric buses (BEBs) is crucial for enhancing their energy efficiency. Therefore, it is crucial to identify the subsystems that contribute most to energy consumption and understand how operational factors influence them. This paper presents a comprehensive analysis of BEB energy consumption based on experimental measurements performed with a 12 m fully electric battery bus. The main limitations of this study stem from the use of a single vehicle over a total period of 18 days, during which 187 routes were completed. Additionally, sandbags were used as ballast in place of actual passengers. Various parameters, including the number of passengers, drivers, route characteristics, environmental conditions, and traffic, were analyzed to assess their impact on BEB energy consumption. Data related to the energy consumed by various bus utilities were collected through the vehicle’s CAN network, with a sampling rate of 1 measurement per second. These data were analyzed both daily and per route, revealing the breakdown of energy consumption among different utilities and highlighting those responsible for the highest energy use. The results correlate the total distance traveled, service duration, average speed, driver’s driving style, route characteristics, internal and external temperatures, and air-conditioning system’s reference temperature with the energy consumption of the traction motors and climate control system. In addition, the correlation between the driver, vehicle acceleration, and throttle pedal use, and the energy consumed by the electric traction motor is presented
