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.
LAS COMPETENCIAS DEL PROFESORADO EN TIC: ESTRUCTURA BÁSICA
2013
Las competencias en TIC del profesorado son una variable clave para la integración de las TIC en la escuela. Este artículo presenta un esquema de indicadores de competencia para dos dimensiones, competencias tecnológicas y competencias pedagógicas, desde un modelo MIMIC. El modelo incluye la definición de una relación específica entre estas dimensiones y también de los efectos de un conjunto de factores relevantes: personales (género, edad y frecuencia de uso del ordenador) y contextuales (tipo de centro, etapa educativa y acceso al aula de informática). La información se recogió mediante un cuestionario aplicado a una muestra de 868 profesoras y profesores de educación primaria y secundari…
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…
Passaggi aerei: suggestioni per un progetto
2011
The paper reports some suggestions useful for designing the small footbridge in the Archaeological Park named "Valle dei Templi" in Agrigento. The aim of the collection of different kinds of examples related to the design of bridges, footbridges and "aerial passageways" between buildings is to describe in which way -by using contemporary architectural "languages"- it is possible to solve the problem related to the necessity of climbing over an obstacle like a river, a street, a bunch of railways and so on, without interrupting the continuity of the pedestrians passage. Different kind of structures and materials are shown by underlining their potentialities in order to solve the pro¬b¬lems r…
