PERMANENZE E VARIAZIONI DEL PAESAGGIO TECNOLOGICO
2019
Il saggio presenta i risultati di un lavoro di ricerca condotto sulle emergenze tecnologiche della città di Palermo che si caratterizzano come elementi del paesaggio urbano. In particolare i sistemi di trasporto dell'acqua e dell'energia del gas per l'illuminazione delle strade hanno contribuito a definire l'immagine del paesaggio urbano costruendo un sistema di relazioni che anche dopo la demolizione di alcuni di questi baluardi hanno mantenuto una riconoscibilità. La trattazione contribuisce a delineare il tema comune a tutti i saggi che caratterizzano la pubblicazione della comunicazione del paesaggio attraverso diversi sistemi di trasmissione delle informazioni.
Injury and Throwing Distance in Teenage Cyclist- Vehicle Crash
2016
The study of the injury caused by vehicle-teenage cyclist crash is presented in this paper. The results of the crash with three vehicles: sedan, SUV and Pick up are compared. Three different positions are analyzed: front, rear and lateral position. The injury on the cyclist head is examined by HIC criterion, in the way indicated by the rules. A comparison is done between the results of the simulations for Pick up, SUV and sedan, concluding that the injury of the head is more dangerous for Pick-up impact than SUV or the sedan, but only at greater speed than 40 km/h. Teenage cyclist is more likely to suffer an injury to the chest in rear impacts with the sedan, because 3 ms values remain abov…
Teenage cyclist - Pick up crash by multibody simulation; HIC evaluation and comparison with previous results
2016
The study of the injury caused by Pick-up vehicle-teenage cyclist crash is presented in this paper. The vehicle has high frontal part, in order to compare the results with those obtained previously in the sedan and SUV - teenage cyclist crash. No variation is executed on the model of the teenage cyclist and the bike. Three different positions are analyzed: front, rear and lateral position. The injury on the cyclist head is examined by HIC criterion, in the way indicated in the rules. Correlation HIC – AIS is used to calculate the lethality of the injuries. A comparison is made between the results of the simulations for Pick up, SUV and sedan, concluding that the injury of the head is more d…
Biomechanics Parameters in Teenage Cyclist – SUV Accident and Comparison with the Pedestrian
2015
The study of the injury caused by the vehicle-teenage cyclist crash is presented in this paper. The vehicle is a SUV, with high frontal part, in order to compare the results with those obtained previously in the sedan- teenage cyclist crash and begin a study of the influence of the frontal shape of the vehicle. No variation is executed on the model of the teenage cyclist and the bike. Three different positions are analyzed: front, rear and lateral position. The injury on the cyclist head is examined by HIC criterion, in the way indicated in the rules. Correlation HIC – AIS is used to calculate the lethality of the injuries. The principal conclusion is done that the injury of the head is mor…
A New Theoretical Approach on Teenage Cyclist-Vehicle Crash
2016
Data obtained in teenage cyclist impact against three vehicles (sedan, SUV and Pick Up), tested in previous works, are analyzed to verify the theoretical results by the coupling of momentum conservation principle and energy conservation principle. The speed of vehicle and thorax are compared with theoretical ones, obtaining an excellent agreement. Following the results found in the literature, particular emphasis is done on teenager cyclist thorax and head speeds, indicating that the cyclist speed can be theoretically until 1,41 times the impact speed, while greater values, until 2, are obtained in the simulations. A small slowing of the vehicle is found theoretically and in the simulations…
Mäntän kaupungin muutos tehdaskaupungista taidekaupungiksi
2011
Metsäteollisuuden deindustrialisaatio on aiheuttanut uudelleen rakenteistumista, mikä vaikuttaa pieniin asutuskeskuksiin jotka aiemmin ovat olleet riippuvaisia paperi- ja selluloosatehtaista. Pro gradu –työssäni olen kuvaillut ja analysoinut tapoja joilla Mänttä, pieni paperiteollisuuskaupunki, on selvinnyt suurista muutoksista. Mänttä on vastannut muutoksiin pyrkimällä investoimaan kulttuuriin ja taiteeseen. Mänttä pyrkii nykyään profiloitumaan ”taidekaupunkina”, sillä siellä järjestetään lukuisia taidenäyttelyitä ja kulttuuritapahtumia. Vuonna 2006 Mänttä haki Euroopan kulttuuripääkaupungin titteliä mutta ei saanut sitä. Olen analysoinut Mäntän muutosprosessia tehdaskaupungista taidekaupu…
The Use of Multimodal Resources by Technical Managers and Their Peers in Meetings Using English as the Business Lingua Franca
2020
Background: Engineers increasingly work and advance their careers in international business settings. As technical managers, they need management and technical skills when working with different stakeholders with whom they may not share a common first language. Studies have revealed that informal oral communication skills are of prime importance for global engineers who face challenges in building shared meaning and formulating clear messages in meetings with non-native speakers of English. This article proposes that studying the use of multimodal resources (spoken language, gaze, gestures, and objects) in meetings can unpack how work tasks are accomplished in business through different com…
Performance of Lead-Acid Batteries with Nanostructured Electrodes at Different Temperature
2018
In this work we present innovative lead-acid batteries with nanostructured electrodes, which are cycled in a wide range of temperatures typically of lead-acid commercial batteries (EN 61427-1: 2013). In comparison to parameters usually used to commercial batteries, much more stressful conditions in terms of cut-off, charge/discharge rate and discharge were imposed.
High-Performance Lead-Acid Batteries Enabled by Pb and PbO2 Nanostructured Electrodes: Effect of Operating Temperature
2021
Lead-acid batteries are now widely used for energy storage, as result of an established and reliable technology. In the last decade, several studies have been carried out to improve the performance of this type of batteries, with the main objective to replace the conventional plates with innovative electrodes with improved stability, increased capacity and a larger active surface. Such studies ultimately aim to improve the kinetics of electrochemical conversion reactions at the electrode-solution interface and to guarantee a good electrical continuity during the repeated charge/discharge cycles. To achieve these objectives, our contribution focuses on the employment of nanostructured electr…
