L’effet des pots acoustiques du caveau phonocamptique de la cathédrale de Noyon : analyse modale et performance chantée
2016
International audience; Au CFA de 2014 nous présentions le caveau phonocamptique de la Cathédrale de Noyon qui comporte, dans un espace souterrain réduit (15 m²), un nombre important de pots acoustiques (64). L’étude des livres liturgiques et de la documentation de la cathédrale (XVe-XVIIe siècles) ne permet pas à ce jour d’identifier le rôle et l’usage de ce caveau. Pourtant, les études archéologiques et acoustiques que nous avions présentées en 2014 montraient le soin qu’avaient pris les bâtisseurs pour élaborer cet espace : deux modèles de pots de hauteurs différentes, correspondant à deux fréquences moyennes proches d’une quarte musicale, une répartition choisie dans l’espace et un trav…
Detecting Kernel Vulnerabilities During the Development Phase
2015
Testing is one of the major problems in Linux kernel development cycle. Security analysis and ensuring no new vulnerabilities has been introduced is one of the toughest issues of testing. Kernel developers attempt to find as many security issues as possible before merging with the mainline branch. Failure to detect vulnerabilities will result in vulnerable kernel shipped by distribution and vulnerable systems. The kernel developers can choose between several industrial and open source tools to assist in the development process and shorten the development cycle. (Though not as many as user space developers. Kernel tools are limited and rare compared to user space tools) Some of these tools a…
La Investigación Acción Participativa (IAP) en el sector empresarial. Interviniendo desde lo local
2019
El artículo muestra el potencial de aplicación de las metodologías participativas de investigación y planeación social para una gestión participativa del conocimiento y el desarrollo de estrategias de intervención en el territorio. En este contexto se muestra una investigación realizada en base a metodologías de investigación acción-participación implementadas en una iniciativa empresarial de una localidad de la Comunidad Valenciana. Así, el carácter influyente y la capacidad de integrar saberes, conocimientos y aprendizajes de los diversos actores sociales e institucionales favorecen la promoción y el desarrollo de estrategias capaces de dar respuesta a las distintas problemáticas existent…
Making Gibellina Nuova
2012
The 1968 earthquake destroyed the Sicilian town Gibellina. The citizens were then moved into a New City drawn by the Institute for Social Building Development ISES in a plain formerly used only for agriculture. How to give identity to an urban infrastructural system spread between fields? Quaroni and Anversa, who were comissioned to construct the building of the main church, combined the necessity of identity with a symbol of the city's rebirth project. The dome of the church is a spherical structure, recognizable in this way from close-up as well as from far away. “To make the city” it is necessary to embed the church into a context through the design of public space. Only then, Quaroni’s …
FARE SPAZIO : Latina dalla fondazione alla contemporaneità
2018
FARE SPAZIO ha l’obiettivo di esplorare nuovi strumenti di ascolto e azione che offrono una visione alternativa della città, nuovi dispositivi di indagine e conoscenza, di interpretazione e rappresentazione del territorio, capaci di restituirne la molteplicità, le stratificazioni. E’ una riflessione cross-disciplinare su Latina e il suo territorio (e sull’urbano tout court), andando oltre la descrizione stereotipata per scorgere le trasformazioni della città. Una narrazione sensibile che guarda alle pratiche artistiche e culturali e all’esercizio di diverse metodologie come strumenti prediletti per leggere la complessità e al contempo creare nuove possibilità, nuovi immaginari.
Privileged places in the city: urban quality, livability, sustainability
2022
Public spaces are privileged places in the city. Unfortunately, conurbation phenomena have taken over, leaving local places and identities to disintegrate, marking a clear break between community and settlement, obstructing the common good and the use of public spaces. To improve well-being and quality of life, public spaces must be attractive and safe, which is why they must be designed according to principles that meet the needs and expectations of all citizens, with particular attention to the weakest, as indicated in the Public Space Charter in 2013, in line with the European Landscape Convention and the United Nations Program for Human Settlements (UN-Habitat). Seniors and children mus…
Enhancing Metastability by Dissipation and Driving in an Asymmetric Bistable Quantum System.
2018
The stabilizing effect of quantum fluctuations on the escape process and the relaxation dynamics from a quantum metastable state are investigated. Specifically, the quantum dynamics of a multilevel bistable system coupled to a bosonic Ohmic thermal bath in strong dissipation regime is analyzed. The study is performed by a non-perturbative method based on the real-time path integral approach of the Feynman-Vernon influence functional. We consider a strongly asymmetric double well potential with and without a monochromatic external driving, and with an out-of-equilibrium initial condition. In the absence of driving we observe a nonmonotonic behavior of the escape time from the metastable regi…
Highly occupied gauge theories in 2 + 1 dimensions : a self-similar attractor
2019
Motivated by the boost-invariant Glasma state in the initial stages in heavy-ion collisions, we perform classical-statistical simulations of SU(2) gauge theory in 2+1 dimensional space-time both with and without a scalar field in the adjoint representation. We show that irrespective of the details of the initial condition, the far-from-equilibrium evolution of these highly occupied systems approaches a unique universal attractor at high momenta that is the same for the gauge and scalar sectors. We extract the scaling exponents and the form of the distribution function close to this non-thermal fixed point. We find that the dynamics are governed by an energy cascade to higher momenta with sc…
Topics in calculus and geometry on metric spaces
2022
In this thesis we present an overview of some important known facts related to topology, geometry and calculus on metric spaces. We discuss the well known problem of the existence of a lipschitz equivalent metric to a given quasiultrametric, revisiting known results and counterexamples and providing some new theorems, in an unified approach. Also, in the general setting of a quasi-metric doubling space, suitable partition of unity lemmas allows us to obtain, in step two Carnot groups, the well known Whitney’s extension theorem for a given real function of class C^m defined on a closed subset of the whole space: this result relies on relevant properties of the symmetrized Taylor’s polynomial…
Experimental Engineering of Arbitrary Qudit States with Discrete-Time Quantum Walks
2019
The capability to generate and manipulate quantum states in high-dimensional Hilbert spaces is a crucial step for the development of quantum technologies, from quantum communication to quantum computation. One-dimensional quantum walk dynamics represents a valid tool in the task of engineering arbitrary quantum states. Here we affirm such potential in a linear-optics platform that realizes discrete-time quantum walks in the orbital angular momentum degree of freedom of photons. Different classes of relevant qudit states in a six-dimensional space are prepared and measured, confirming the feasibility of the protocol. Our results represent a further investigation of quantum walk dynamics in p…
