Ghost stochastic resonance in FitzHugh–Nagumo circuit
2014
International audience; The response of a neural circuit submitted to a bi-chromatic stimulus and corrupted by noise is investigated. In the presence of noise, when the spike firing of the circuit is analysed, a frequency not present at the circuit input appears. For a given range of noise intensities, it is shown that this ghost frequency is almost exclusively present in the interspike interval distribution. This phenomenon is for the first time shown experimentally in a FitzHugh-Nagumo circuit.
Towards Process Centered Architecting for Quantum Software Systems
2022
Quantum Software Engineering (QSE) is a recent trend - focused on unifying the principles of quantum mechanics and practices of software engineering - to design, develop, validate, and evolve quantum age software systems and applications. Software architecture for quantum computing (a.k. a. quantum software architectures (QSA)) supports the design, development, and maintenance etc. phases of quantum software systems using architectural components and connectors. QSA can enable quantum software designers and developers to map the operations of Qubits to architectural components and connectors for implementing quantum software. This research aims to explore the role of QSAs by investigating (…
The state of research on software engineering competencies: A systematic mapping study
2022
Considering the critical role of software in modern societies, we face an urgent need to educate more competent software professionals. Software engineering competencies (SEC) are considered the backbone of successfully developing software products. Consequently, SEC has become a hotspot for software engineering research and practice. Although scientific literature on SEC is not lacking, to our knowledge, a comprehensive overview of the current state of SEC research is missing. To that end, we conducted an extensive and systematic review of the SEC literature. We provide an overview of the current state of research on SEC, with a particular focus on common SEC research areas. In addition to…
Fonti per la storia del Manicomio di Palermo alla Vignicella (1884-1902)
2020
Il testo ripercorre le tappe che hanno condotto alla realizzazione di una delle più vaste opere pubbliche di stampo sanitario realizzate a Palermo nel XIX secolo: l'Ospedale Psichiatrico alla Vignicella. Tramite l’individuazione e l’analisi delle principali fonti ottocentesche e dei primissimi del Novecento, pur confrontandosi con la più recente letteratura periegetica, si fissano alcuni punti fermi rispetto alla progettazione ed esecuzione dei lavori, oltre che, non di meno, in relazione alla concezione scientifica sulle quali erano state fondate. Le immagini d’epoca accompagnano il testo in senso illustrativo e documentario. The text traces the steps that led to the construction of one of…
‘The best guess for the future?’ Teachers’ adaptation to open and flexible learning environments in Finland
2021
Finnish education has recently experienced reforms with respect to guidelines forming the curriculum framework for basic education and school architecture. Since 2016, all new schools incorporate open and flexible design, at least to some extent. The more open school design challenges the conventional organisation of space and pre-defined structures and interaction practices. This study investigates how teachers both adapt and are affected by new demands for pedagogy, team teaching and teacher-student relationships. Interview data of 21 teachers of six modern schools are reviewed through thematic analysis. The new school layouts provided some incongruence with the teachers’ aims and their p…
The relevance of point defects in studying silica-based materials from bulk to nanosystems
2019
The macroscopic properties of silica can be modified by the presence of local microscopic modifications at the scale of the basic molecular units (point defects). Such defects can be generated during the production of glass, devices, or by the environments where the latter have to operate, impacting on the devices’ performance. For these reasons, the identification of defects, their generation processes, and the knowledge of their electrical and optical features are relevant for microelectronics and optoelectronics. The aim of this manuscript is to report some examples of how defects can be generated, how they can impact device performance, and how a defect species or a physical phenomenon …
LA CONVENANCE DE L’ORNEMENT : UNE QUESTION ÉTHIQUE ?
2019
Nell'era contemporanea, in cui gli architetti sono spesso alla ricerca di una bellezza spettacolare, la questione dell'ornamento trova un'importante attualità nel dibattito filosofico e architettonico. La domanda è se l'ornamento non abbia una dimensione etica. Per rispondere, studierò qui tre momenti storici decisivi di questo dibattito: la teoria dell'armonia di Alberti, l'approccio della scuola di Chicago alle relazioni di forma e funzione (LH Sullivan e J. Root) e la critica dell'ornamento in A. Loos. Pur appartenendo a diversi orizzonti culturali, queste teorie possono far luce sul dibattito contemporaneo svelando la dimensione etica e non solo quella estetica dell'ornamento. In contem…
GPU-accelerated time integration of Gross-Pitaevskii equation with discrete exterior calculus
2022
The quantized vortices in superfluids are modeled by the Gross-Pitaevskii equation whose numerical time integration is instrumental in the physics studies of such systems. In this paper, we present a reliable numerical method and its efficient GPU-accelerated implementation for the time integration of the three-dimensional Gross-Pitaevskii equation. The method is based on discrete exterior calculus which allows us the usage of more versatile spatial discretization than traditional finite difference and spectral methods are applicable to. We discretize the problem using six different natural crystal structures and observe the correct choices of spatial tiling to decrease the truncation error…
L'EVALUATION DES PERFORMANCES ET LE DEGRE D'AUTONOMIE DES ACTEURS LOCAUX : LE CAS DES BANQUES DE RESEAU.
2009
The structure of the system to evaluate the performance in the banking sector is poorly studied in France. We don't have many information about Organizational Architecture of retail banks although manager argue that branches are important to generate regular revenues. The questions are numerous : how are branches managed ? are the decision rights equally assigned in branches among all the banking sector ? And what's about the specificity of mutual banks ? The aim of the study if to answer theses questions and try to elaborate a typology between mutual and commercial bank.
Digital Architectures Generated Using Forces in Urban Environment
2008
A paper, a description of a software application is given, which allows to generate tridimensional models of buildings, directly inside a geo referential context, following a parametric approach, in which the volume of the building is put in direct relation with forces/law bonds emerging from the urban context. The user is, therefore, able to interactively operate within a project process, in which by changing the parameters values and by verifying in real time, the results of the changes, he/she is able to evaluate all possible infinite scenarios. The system,thought for Trento’s (Italy) urban context, may also be applied on other cities.
