PUMP AS TURBINE (PAT) IN INTERMITTENT DISTRIBUTION NETWORKS
2012
A hydraulic model was performed in order to evaluate potential energy recovery resulting by the use of centrifugal pump as turbines (PAT) in the water distribution network characterized by the presence of private tanks. The model integrates the Enhanced Global Gradient Algorithm (EGGA) (Todini [1], Giustolisi et al. [2]), with a pressure driven model (Criminisi et al. [3]) that entails a more realistic representation of the influence of the private tanks filling and emptying process in the network behaviour. The model was applied to real case study: a district metered area in Palermo (Italy). Namely three different scenarios were analyzed and compared with the actual scenario (Scenario 0 - …
Learning Pros and Cons of Model-Driven Development in a Practical Teaching Experience
2016
Current teaching guides on Software Engineering degree focus mainly on teaching programming languages from the first courses. Conceptual modeling is a topic that is only taught in last courses, like master courses. At that point, many students do not see the usefulness of conceptual modeling and most of them have difficulty to reach the level of abstraction needed to work with them. In order to make the learning of conceptual modeling more attractive, we have conducted an experience where students compare a traditional development versus a development using conceptual models through a Model-Driven Development (MDD) method. This way, students can check on their own pros and cons of working w…
Il Paradigma della Città Fluida
2013
Nella recente crisi globale i poderosi flussi di capitali finanziari, sociali e relazionali che hanno alimentato la riqualificazione urbana nel corso degli ultimi quindici anni non sono più disponibili ad essere intercettati in maniera indiscriminata così come è stato possibile fino a qualche anno fa. Nell'era della crisi strutturale le città più dinamiche non sono più quelle in grado di attrarre progetti urbani iconici ed investitori spinti dal mercato immobiliare o dalla redditività delle attività ricreative, ma quelle città che, a partire dalle loro profonde e diversificate risorse culturali, saranno capaci di attuare una vera e propria “metamorfosi” per usarle come base per la creazione…
Towards a validated definition of the clinical transition to secondary progressive multiple sclerosis: A study from the Italian MS Register.
2022
Background: Definitions for reliable identification of transition from relapsing-remitting multiple sclerosis (MS) to secondary progressive (SP)MS in clinical cohorts are not available. Objectives: To compare diagnostic performances of two different data-driven SPMS definitions. Methods: Data-driven SPMS definitions based on a version of Lorscheider’s algorithm (DDA) and on the EXPAND trial inclusion criteria were compared, using the neurologist’s definition (ND) as gold standard, in terms of sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), Akaike information criterion (AIC) and area under the curve (AUC). Results: A cohort of 10,240 MS patients wi…
To Move or Not to Move. That is the question.
2011
International audience; In the same way that scientists have to "Publish or perish!", medical students, residents and young doctors in France have to "Move or perish!". "La mobilité" (professional mobility) has become a key word in French medical circles. Thus, in 2003, a group of English teachers at the Dijon School of Medicine and at ENS-Lettres et Sciences Humaines (Lyon) conducted a mobility-related needs assessment to identify how we could help young professionals prepare for their stay abroad in English-speaking environments. To assess the actual needs of French professionals, we first contacted a cardiovascular surgeon, Eric Steinmetz, who had spent one year as a research fellow in S…
Model-Driven Development Approach for Providing Smart Home Services
2009
Smart home is about the application of automation techniques for the comfort and security of residents' privately owned homes. In a smart home environment, different and independent embedded devices provide services that can be freely used by others, in the sense of service invocation. This paper presents our idea of using Model Driven Development (MDD) for the composition of existing services, by which we aim at demonstrating how new smart home services will be promoted.
Laboratory formation of a scaled protostellar jet by coaligned poloidal magnetic field
2014
International audience; Although bipolar jets are seen emerging from a wide variety of astrophysical systems, the issue of their formation and morphology beyond their launching is still under study. Our scaled laboratory experiments, representative of young stellar object outflows, reveal that stable and narrow collimation of the entire flow can result from the presence of a poloidal magnetic field whose strength is consistent with observations. The laboratory plasma becomes focused with an interior cavity. This gives rise to a standing conical shock from which the jet emerges. Following simulations of the process at the full astrophysical scale, we conclude that it can also explain recentl…
Organizational Culture Challenges of Adopting Big Data: A Systematic Literature Review
2019
Part 2: Big Data Analytics; International audience; The interest of adopting big data (BD) in organizations has emerged in recent years. Even though many organizations have attempted to adopt BD, the benefits gained by this investment has been limited, and organizations struggle to fully utilize the potential of BD. There has been done several studies on the different challenges and benefits that may occur during the process of adopting and using BD. One major factor that has been discussed in the literature to overcome such challenges has been organizational culture. This paper aims to provide a systematic literature review that reports the organizational culture’s impact on BD adoption th…
An Inquiry-based approach to the Franck-Hertz experiment
2014
In this study we present the results of an inquiry-driven learning path experienced by a sample of 15 selected engineering undergraduates engaged to perform the Franck-Hertz experiment. Before being involved in this experimental activity, the students received a traditional lecture-based instruction on the fundamental concepts of quantum mechanics. Despite the instructor’s introduction to specific technological/engineering-based contents during the course, the students’ answers to an open-ended questionnaire, administered at the end of the lectures, demonstrated that the acquired knowledge was characterized by a strictly theoretical vision of quantum science, basically in terms of an artifi…
Un approccio design-driven alla validazione delle pratiche collaborative per l’economia circolare urbana
2022
L’articolo esplora i metodi e i processi seguiti nella validazione di pratiche collaborative per l’economia circolare urbana. I contenuti presentati sono il risultato dell’attività di ricerca condotta nell’ambito di Reflow, un progetto di ricerca europeo H2020 focalizzato sullo sviluppo di pratiche innovative dedicate a metabolismi urbani circolari. A partire dalla revisione della letteratura e dall’analisi di pratiche relative ai processi collaborativi per l’economia circolare, la pubblicazione identifica una serie di concetti chiave per l’implementazione di progetti di circolarità urbana, evidenziando l’assenza di metodi e strumenti condivisi per la validazione di azioni circolari su larg…
