Increasing the flexural capacity of RC beams using steel angles and pre-tensioned stainless steel ribbons

2016

This article presents an experimental programme on reinforced concrete beams retrofitted with steel angles and pre-stressed stainless steel ribbons to increase their flexural strength and ductility. Two different configurations of the steel ribbon were designed, and two companion specimens for each type considered were subjected to a four-point bending test to facilitate a direct comparison in the analysis of the effectiveness of the retrofitting technique. The influence of longitudinal steel angles and transverse stainless steel ribbons is analysed, and the concrete confinement due to stainless steel ribbons examined. The strengthened beams show remarkable increments in flexural strength a…

Modélisation et analyse spatiales des pratiques de mobilité partagée et de transport flexible en région PACA

2019

En France métropolitaine, en 2018, on estime que les transports contribuent à environ 40 % dans l'émission du dioxyde de carbone atmosphérique, et consomment un tiers de l'énergie produite (ADEME, 2018). L'objectif de neutralité carbone fixé par l'État vise une réduction de 40 % des gaz à effet de serre dès 2030, puis 75 % à l'horizon 2075. Dans ce contexte, la région PACA a réduit de 22 % ses émissions entre 2000 et 2017, pour une baisse moyenne de 30 % au niveau de la France sur la même période. Face aux enjeux environnementaux, la région PACA, comme la plupart des régions françaises, se doit de réduire drastiquement ses émissions de polluants atmosphériques liés aux transports routiers. …

Què serà de la filosofia en el segle XXI?

2004

És normal que el fet de trobar-nos no sols a les acaballes d'un segle, sinó també d'un miHenni, ens provoque reflexions escatològiques diverses; també la filosofia pot ser objecte d'aquest tipus de reflexions que poden ben bé acompanyar un estudi sobre el que ha fet (i continua fent) la filosofia a la segona meitat del segle XX.

Multi-Energy School System for Seasonal Use in the Mediterranean Area

2020

School buildings represent an energy-consuming sector of real estate where different efficiency actions are necessary. The literature shows how the design of a multi-energy system offers numerous advantages, however, there are problems related to the integration of cogeneration units with renewable energy sources due to the low flexibility of the first one and the high degree of uncertainty of the latter. The authors provide an alternative solution through the analysis of a case study consisting of a multiple energy system in three Sicilian schools, focusing on the system&rsquo

Why know myself? Flexible behaviour and the need for self-modelling: Poster

2021

In this paper I argue that some forms of the capacity for behavioural flexibility entail a specific kind of representation, a self-model. This means that systems with that capacity, among them human beings, must have self-models. In its basic form, the capacity for behavioural flexibility allows a system to respond to the same sensory stimulus differentially, depending on the values of parameters with which it represents the world. On seeing a street, I might cycle straight ahead or take a sharp turn left – depending on whether I represent it to blocked off just around the corner. More advanced forms expand on this. Self-models are a form of self-representation in which states are represent…

Developments in the biomechanics and equipment of Olympic cross-country skiers

2018

Source at: http://doi.org/10.3389/fphys.2018.00976 Here, our aim was to describe the major changes in cross-country (XC) skiing in recent decades, as well as potential future developments. XC skiing has been an Olympic event since the very first Winter Games in Chamonix, France, in 1924. Over the past decades, considerable developments in skiing techniques and improvements in equipment and track preparation have increased skiing speed. In contrast to the numerous investigations on the physiological determinants of successful performance, key biomechanical factors have been less explored. Today’s XC skier must master a wide range of speeds, terrains, and race distances and formats (e.g., dis…
