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.
Progettazione e valutazione inclusiva con gli EAS Metodologie, ricerche e strumenti
2022
Il testo affronta il tema della didattica inclusiva per Episodi di Apprendimento Situato (EAS), dispositivo metodologico in grado di professionalizzare le pratiche degli insegnanti e rendere gli allievi centro dei loro apprendimenti. A partire da una prima parte metodologico-applicativa, il lavoro è integrato da una sperimentazione condotta in due contesti inclusivi differenti: le scuole speciali in Spagna (CEE) e la scuola ordinaria italiana. In entrambi i contesti, al termine del percorso di sperimentazione, si è evidenziato un miglioramento auto-percepito delle competenze metodologiche e digitali possedute dagli insegnanti.
Inverting Multiple Residual Stress Components from Multiple Cuts with the Contour Method
2007
An extension of the contour method is presented which allows the measurement of multiple stress components by making multiple cuts. In the contour method, a body is carefully cut in two using wire electric discharge machining (EDM). The contours, or shapes, of the cut surfaces are then measured and used to calculate the original residual stress normal to the cut plane using a simple finite element calculation. In the extension presented here, the two pieces from the original body can be cut again in a transverse direction, and the contours of the new cut surfaces are measured. The stresses calculated on the planes of these second cuts have been affected by the first cut. Then a simple inver…
L'elemento soggettivo e la didattica della progettazione architettonica
2008
Ogni anno, con una certa quantità di ripetizioni e di innovazioni, si procede alla stesura di un programma didattico che, articolato in più voci (collocazione nel progetto formativo, obiettivi, contenuti, modalità d’esame, bibliografia essenziale), struttura le tappe di un percorso nei mesi in cui si sviluppa l’insegnamento. Nella presente riflessione, senza svalutare in alcun modo le conoscenze oggettive che possono concretizzarsi in una interpretazione dei punti della teoria della progettazione di Rossi, si vuole individuare un percorso didattico che parta dalla componente autobiografica dello studente. Per affrontare tale questione si dovrebbe spostare l’attenzione sul modo in cui gli…
Conformable eddy current array delivery
2016
The external surface of stainless steel containers used for the interim storage of nuclear material may be subject to Atmospherically Induced Stress Corrosion Cracking (AISCC). The inspection of such containers poses a significant challenge due to the large quantities involved; therefore, automating the inspection process is of considerable interest. This paper reports upon a proof-of-concept project concerning the automated NDT of a set of test containers containing artificially generated AISCCs. An Eddy current array probe with a conformable padded surface from Eddyfi was used as the NDT sensor and end effector on a KUKA KR5 arc HW robot. A kinematically valid cylindrical raster scan path…
KNOWN RESIDUAL STRESS SPECIMENS USING OPPOSED INDENTATION
2009
In order to test new theories for residual stress measurement or to test the effects of residual stress on fatigue, fracture, and stress corrosion cracking, a known stress test specimen was designed and then fabricated, modeled, and experimentally validated. To provide a unique biaxial stress state, a 60 mm diameter 10 mm thick disk of 316L stainless steel was plastically compressed through the thickness with an opposing 15 mm diameter hard steel indenters in the center of the disk. For validation, the stresses in the specimen were first mapped using time-of-flight neutron diffraction and Rietveld full pattern analysis. Next, the hoop stresses were mapped on a cross section of two disks usi…
Robotic path planning for non-destructive testing of complex shaped surfaces
2015
The requirement to increase inspection speeds for non-destructive testing (NDT) of composite aerospace parts is common to many manufacturers. The prevalence of complex curved surfaces in the industry provides significant motivation for the use of 6 axis robots for deployment of NDT probes in these inspections. A new system for robot deployed ultrasonic inspection of composite aerospace components is presented. The key novelty of the approach is through the accommodation of flexible robotic trajectory planning, coordinated with the NDT data acquisition. Using a flexible approach in MATLAB, the authors have developed a high level custom toolbox that utilizes external control of an industrial …
DETERMINATION AND ANALYSIS OF HEAD AND CHEST PARAMETERS BY SIMULATION OF VEHICLE-TEENAGER IMPACT
2013
This paper reports the results of multi-body numerical simulation of a vehicle crash with a teenager pedestrian. A previous technique utilized for adult pedestrian impact is applied. The work starts with the determination of the masses for the various segments of the body of a teenager with a total mass of 45 kg and then switches to the construction of the dummy and the middle-class vehicle in the Visual Nastran environment. Simulations are performed for both frontal impacts and lateral impacts, when the vehicle is travelling at a constant speed and when the vehicle is braking, following the Euro NCAP rules on the subject. The results are analysed by calculating the values of the head inju…
FE Calculation Methodology for the Thermodynamic Fatigue Analysis of an Engine Component
2006
Thermo mechanical fatigue problem is treated to define an analysis methodology permitting the strength evaluation by reliability viewpoint. The main difficulty is the lack of both theoretical and experimental information; consequently the problem is treated verifying continually the validity and the limits of the developing solution method. The main task of the activity described in this paper was the development of a numerical methodology, based on FE analyses, for the evaluation of the structural behavior of engine components subjected to thermo mechanical fatigue phenomena. The chosen application was the exhaust manifold of an IC engine; FE analyses were executed following the standard m…
