Città della prossimità aumentata

2021

La sfida per le città aumentate antisindemiche sarà quella di recuperare il loro naturale policentrismo, la diversità dei loro quartieri e borgate che, smettendo di essere fragili periferie senza diritti, tornino ad essere luoghi di vite e non solo di abitazioni, colmando il divario educativo, lavorativo, sanitario, culturale, digitale, dotandosi di micro-presìdi di salute pubblica e di comunità energetiche autosufficienti. Immagino città fondate su una nuova prossemica che riduca la loro forsennata mobilità centripeta, garantendo la risposta a molti bisogni entro un raggio di 15 minuti a piedi (lo stanno già facendo Parigi, Barcellona, Milano, Bologna). Voglio proporre qui una “città della…

Attitude measurement by artificial vision

2005

The recent development of light and low-cost airborne platforms (microlight, drones, kites, balloons,...) has led to the need for simple and low-cost devices allowing attitude measurement with respect to a reference horizon of the platform itself or of an embedded setting. A theoretical study of the conditions for measuring attitude angles from artificial vision is proposed and an original practical algorithm allowing these measurements to be performed in real time is described. An implementation in a CMOS retina circuit is also presented. These points are illustrated by experiments confirming the feasibility of the device.

Effect of stiffness on the phase behavior of cubic lattice chains

2005

Gran canonica Monte Carlo (GCMC) simulazioni assistite da tecniche di riponderazione istogramma sono stati utilizzati per studiare l'effetto della flessibilità catena sul comportamento di soluzione fase di cubi catene reticolari corti con 4-32 segmenti. Ciò è stato fatto variando un parametro di rigidità gradualmente fino alla media calcolata end-to-end distanza avvicinato la lunghezza totale. Per entrambe le catene flessibili e rigide si è riscontrato che la temperatura critica, ottenuta tramite mista analisi dei campi di dimensioni finite, aumentata lunghezza della catena e la densità critica trasferisce a valori più bassi, in accordo con le osservazioni sperimentali. Il estrapolato lungh…

Measurement of the muon neutrino inclusive charged-current cross section in the energy range of 1–3 GeV with the T2K INGRID detector

2016

International audience; We report a measurement of the $\nu_{\mu}$-nucleus inclusive charged current cross section (=$\sigma^{cc}$) on iron using data from exposed to the J-PARC neutrino beam. The detector consists of 14 modules in total, which are spread over a range of off-axis angles from 0$^\circ$ to 1.1$^\circ$. The variation in the neutrino energy spectrum as a function of the off-axis angle, combined with event topology information, is used to calculate this cross section as a function of neutrino energy. The cross section is measured to be $\sigma^{cc}(1.1\text{ GeV}) = 1.10 \pm 0.15$ $(10^{-38}\text{cm}^2/\text{nucleon})$, $\sigma^{cc}(2.0\text{ GeV}) = 2.07 \pm 0.27$ $(10^{-38}\te…

Skin conductance measurement for the assessment of analgosedation adequacy in infants treated with mechanical ventilation: A multicenter pilot study

2020

Background Patients treated in neonatal/pediatric intensive care units (N/PICUs) are frequently exposed to pain. To assess its severity, several behavioral and behavioral-physiological scales are used, but their usefulness is limited. It is therefore justified to search for additional methods to assess the adequacy of analgesia and sedation in these patients. Objectives To evaluate the usefulness of skin conductance (SC) measurement in the assessment of analgosedation quality in infants requiring mechanical ventilation treated in N/PICUs. Material and methods Thirty infants aged 6-208 days treated in 6 N/PICUs, mechanically ventilated and receiving analgosedation, were included for the stud…

Concetto, profondità, superficie. Georg Simmel, Theodor W. Adorno e la crisi della modernità

2010

L’indagine filosofica e la sua trasmissione didattica, così come si realizzano nella relazione tra maestro ed allievo, permettono di interrogare ed evidenziare alcuni aspetti cogenti della stessa natura del concetto. In un’ottica adorniana il concetto coglie la realtà tramite la mediazione del linguaggio e la definizione di una terminologia; allo stesso tempo, un tale sforzo definitorio rischia di smarrire la relazione con l’obiettività nella reificazione linguistica. Emerge qui la natura paradossale del concetto, la sua coestensiva eccedenza e insufficienza nei confronti della «cosa». Seppur da prospettive differenti, Georg Simmel e Theodor W. Adorno colgono nella modernità, e nella sua co…

Reliability of numerical models for simulating galvanic corrosion processes

2012

International audience; Maturity of numerical simulation represents an important issue in the development of predictive models of galvanic corrosion. As widely used in electrochemical engineering, a coupled electrochemical-transport-reaction (CETR) model is recommended to simulate the current distribution above a galvanic corrosion cell made of the cut-edge of a galvanized steel sheet. Nevertheless, simulating current density distributions obtained experimentally by scanning vibrating electrode technique (SVET) above such a galvanic cell appears to be more accurate using an electrostatic model considering a homogeneous conductivity. In this case, the absence of concentration gradients next …

Towards a multi-agent model to prevent damage caused by cocoa mirids to cocoa pods

2019

Agriculture in general and cocoa farm in particular is one of the primary sources of income for several African countries. Although quite useful for the development of Africa, cocoa production is faced with several challenges like the diseases of cocoa trees. Mirid (Sahlbergella singularis) is the worst pest affecting cocoa production across west Africa causing 30% to 40% of damage on cocoa production. It is difficult to control the mirids’ population and its impact on the cacao production. Related works on mirids studied the mirids population as a macroscopic entity without considering local interactions of individual mirids. These models did not consider the behaviours and the environment…

La fondazione del monastero di Santa Chiara di Piazza Armerina (1320-1340): un vuoto documentario

2017

ITALIANO: Il numero degli insediamenti francescani femminili in Sicilia nel XIII e XIV secolo è ridotto e la ricostruzione della storia dei pochi monasteri esistenti è resa più complessa dalla mancanza di documenti che accomuna buona parte di essi. È il caso del monastero di Santa Chiara di Piazza Armerina la cui storia trecentesca, a partire dalla fondazione, sembra essere avvolta nell’oblio. Il saggio si propone, sulla scorta dei pochi documenti rinvenuti, di chiarire alcuni elementi legati alla sua fondazione ad opera di Guglielmo Caldarera barone di Bifara e di Favarotta. / ENGLISH: The number of female franciscan settlements in Sicily in the 13th and 14th centuries is limited and the r…
