Buckling and Postbuckling of Stiffened Composite Panels with Cracks and Delaminations by Ritz Approach

2017

A Ritz approach for the analysis of buckling and post-buckling of stiffened composite panels with through-the-thickness cracks and/or delaminations is presented. The structure is modeled as the assembly of plate elements whose behavior is described by the First-order Shear Deformation Theory and von Karman’s geometric nonlinearities. Penalty techniques ensure continuity along the edges of contiguous plate elements and the enforcement of the restraints on the external boundaries. They are also used to avoid interpenetration problems. General symmetric and unsymmetric stacking sequences are considered. A computer code has been developed and used to validate the proposed method, comparing the …

Corporate Sustainability – From a Fuzzy Concept to a Coherent Reality

2018

Abstract During the last few decades, the search for sustainability has experienced a tremendous momentum, encompassing all the levels of the global system. Fuelled by complex (both proactive and reactive) motivators, the process has surpassed the characteristics of an intellectual endeavor – more preoccupied by idealist goals, and less focused on the actual means to achieve them – and has proved that it can successfully be transposed into the corporate real world – of decision making, objective assessment, and relentless scrutiny. The paper aims to (broadly) explore the world of the most sustainable corporations – based on a descriptive (factual and dynamic) analysis of Corporate Knight’s …

Sub specie æternitatis: the role of the ruin and the ancient in the process of architectural renewal between metamorphosis and resurgence

2022

Composing new works of architecture inspired by vestiges from antiquity or archaeology. The reflections and the case study which will be proposed, pertaining to a recent design experiment for the archaeological area and Antiquarium of Tyndaris, are dedicated to this theme. Over and above any charm exerted by such places, by landscapes in which the ruins appear identical in substance and which sometimes manifest themselves as “sub specie æternitatis”, there are reasons linked to the very profession of architect and to the gashes in the crucible of controversies around the role of history in its contentious relationship with architectural design. That apart, the aporias revealed by Michel Fou…

Entro questa concezione della storia o meglio di una metodologia per la storia che "tenda all'archeologia in quanto descrizione intrinseca del monumento" le opere e i progetti di architettura appaiono come i protagonisti di un'azione drammatica incentrata sull'opposizione tra la permanenza della "struttura" e il fremito del mutamento. Quel fremito che nell'età dell'Umanesimo aveva animato le menti degli architetti affrontando allo stesso modo i campi della filologia e dell'architettura studiando i monumenti antichi come testi allo scopo di "generare nuove forme e dare così vita a una nuova classica tradizione".Settore ICAR/14 - Composizione Architettonica E Urbanain sintesi alle trasformazioni che valgono come fondazione e rinnovamento delle fondazioni stesse.&nbspdi Tindari che si proporranno. Al di là e oltre la suggestione esercitata dai luoghi da paesaggi cui i ruderi appaiono consustanziali e che si manifestano talora "sub specie aeternitatis" vi sono motivi legati al mestiere stesso di architetto e alle lacerazioni vissute nel crogiolo delle polemiche intorno al ruolo della storia nel suo controverso rapporto con il progetto di architettura. Del resto le aporie svelate da Michel Foucault mettendo in discussione quello che si era proposto come progetto di una storia globale avevano dato rilievo alla discontinuità alle fratture alle soglieComporre nuova architettura in rapporto con le vestigia dell'antichità o in ambito archeologico.

Integrated satellite data fusion and mining for monitoring lake water quality status of the Albufera de Valencia in Spain

2015

Abstract Lake eutrophication is a critical issue in the interplay of water supply, environmental management, and ecosystem conservation. Integrated sensing, monitoring, and modeling for a holistic lake water quality assessment with respect to multiple constituents is in acute need. The aim of this paper is to develop an integrated algorithm for data fusion and mining of satellite remote sensing images to generate daily estimates of some water quality parameters of interest, such as chlorophyll a concentrations and water transparency, to be applied for the assessment of the hypertrophic Albufera de Valencia. The Albufera de Valencia is the largest freshwater lake in Spain, which can often pr…

noRANSAC for fundamental matrix estimation

2011

The estimation of the fundamental matrix from a set of corresponding points is a relevant topic in epipolar stereo geometry [10]. Due to the high amount of outliers between the matches, RANSAC-based approaches [7, 13, 29] have been used to obtain the fundamental matrix. In this paper two new contributes are presented: a new normalized epipolar error measure which takes into account the shape of the features used as matches [17] and a new strategy to compare fundamental matrices. The proposed error measure gives good results and it does not depend on the image scale. Moreover, the new evaluation strategy describes a valid tool to compare diffe rent RANSAC-based methods because it does not re…

The architecture and Neogene to Recent evolution of the W Calabrian continental margin: an upper plate perspective to the Ionian subduction system (C…

2010

The western Calabria continental margin forms the transition between the Pliocene to Recent Marsili spreading center and continental Calabria, all parts of the upper plate of the Ionian subduction zone. Integrating high-resolution and crustal seismic images constrained by gravity modeling, we provide a detailed reconstruction of the architecture of the margin and develop a new scheme for its Miocene to present evolution. This time span encompasses the continent-continent collision between Africa and Eurasia, subsequent orogenic collapse and rifting apart between the two continental masses, and the Pliocene to Recent emplacement of oceanic crust in the Vavilov and Marsili basins. The crust o…
