Dubai, da città in transizione a città resiliente?
2020
L'articolo presenta il lavoro, Dubai Pop-Up. Architecture in a transient city, esito di un un workshop internazionale di progettazione (coordinato da T. Aglieri Rinella e R. Garcia Rubio) che ha portato al centro la questione Dubai, riunendo un gran numero di docenti e studenti per ragionare sull’introduzione di nuovi modi di pensare la città. Grazie alle diversificate e talvolta sorprendenti ipotesi che i progetti elaborati suggeriscono, appare chiaro quanto possa essere ancora aperto il grado delle alternative a quel modello di sviluppo orientato solamente sulla “monocoltura del profitto” che sino adesso ha guidato le scelte urbane in questa città. The article presents the work "Dubai Pop…
TABLE 3. QUESTIONS DE DURABILITÉ CULTURELLE ET ENVIRONNEMENTALE
2016
Il contributo gli esiti di un forum dei soggetti territoriali, sottolineando come il tema della partecipazione sia un prerequisito per la sostenibilità delle scelte progettuali. L'article porte sur les résultats d'un forum régional du sujet et met l'accent sur la participation comme une exigence pour la durabilité des choix de conception. Le Forum, organisé dans le cadre du programme DO.RE.MI.HE., a représenté l’une des rares occasions de voir plusieurs organismes territoriaux et associations, qui travaillent à divers niveaux sur le territoire, réunis autour d’une même table en vue d’imaginer un futur pour la ville et le territoire au départ du site UNESCO.
New fault detection filter design approach for continues-time switched systems
2012
This paper investigates the problem of fault detection filter design for continuous-time switched systems. The designed fault detection filter is assumed to be asynchronous with the original systems. Attention is focused on designing a fault detection filter such that the estimation error between the residual and the fault is minimized in the sense of H ∞ norm. By employing piecewise Lyapunov function and average dwell time techniques, a sufficient condition for the existence of such a filter is exploited in terms of certain linear matrix inequalities. Finally, an example is provided to illustrate the effectiveness of the proposed approach.
Optimal pareto solutions of a dynamic C chart: An application of statistical process control on a semiconductor devices manufacturing process
2015
The present paper proposes a novel economic-statistical design procedure of a dynamic c control chart for the Statistical Process Control (SPC) of the manufacturing process of semiconductor devices. Particularly, a non-linear constrained mathematical programming model is formulated and solved by means of the ε-constraint method. A numerical application is developed in order to describe the Pareto frontier, that is the set of optimal c charts and the related practical considerations are given. The obtained results highlight how the performance of the developed dynamic c chart overcome that of the related static one, thus demonstrating the effectiveness of the proposed procedure.
A Branch-and-Cut method for the Capacitated Location-Routing Problem
2011
International audience; Recent researches in the design of logistic networks have shown that the overall distribution cost may be excessive if routing decisions are ignored when locating depots. The Location-Routing Problem (LRP) overcomes this drawback by simultaneously tackling location and routing decisions. The aim of this paper is to propose an exact approach based on a Branch-and-Cut algorithm for solving the LRP with capacity constraints on depots and vehicles. The proposed method is based on a zero-one linear model strengthened by new families of valid inequalities. The computational evaluation on three sets of instances (34 instances in total), with 5–10 potential depots and 20–88 …
Earth System Chemistry integrated Modelling (ESCiMo) with the Modular Earth Submodel System (MESSy) version 2.51
2016
Abstract. Three types of reference simulations, as recommended by the Chemistry–Climate Model Initiative (CCMI), have been performed with version 2.51 of the European Centre for Medium-Range Weather Forecasts – Hamburg (ECHAM)/Modular Earth Submodel System (MESSy) Atmospheric Chemistry (EMAC) model: hindcast simulations (1950–2011), hindcast simulations with specified dynamics (1979–2013), i.e. nudged towards ERA-Interim reanalysis data, and combined hindcast and projection simulations (1950–2100). The manuscript summarizes the updates of the model system and details the different model set-ups used, including the on-line calculated diagnostics. Simulations have been performed with two diff…
The on-line coupled atmospheric chemistry model system MECO(n) – Part 5: Expanding the Multi-Model-Driver (MMD v2.0) for 2-way data exchange includin…
2018
Abstract. As part of the Modular Earth Submodel System (MESSy), the Multi-Model-Driver (MMD v1.0) was developed to couple online the regional Consortium for Small-scale Modeling (COSMO) model into a driving model, which can be either the regional COSMO model or the global European Centre Hamburg general circulation model (ECHAM) (see Part 2 of the model documentation). The coupled system is called MECO(n), i.e., MESSy-fied ECHAM and COSMO models nested n times. In this article, which is part of the model documentation of the MECO(n) system, the second generation of MMD is introduced. MMD comprises the message-passing infrastructure required for the parallel execution (multiple programme mul…

Simulation-based design of a bipolar membranes electrodialysis unit for chemicals production from brines
2022
Nowadays environmental concerns are modifying the production and consumption patterns used so far. An important objective to improve our society is the use of sustainable processes that can reduce industrial waste streams. Bipolar membranes electrodialysis (EDBM) is an emerging environmentally friendly process that could be easily integrated into a circular economy approach to valorize waste brines. It is an electro-membrane process that allows the production of chemicals using only water, electrical energy and a salty solution. When electric current is applied to the electrodes of the EDBM stack, water dissociation takes place in the bipolar membranes. Therefore, the ions from water are co…
