The scope of the project is to develop and test methods for designing and implementing innovative and sustainable Strategic Plans for Waste Prevention and Management in various urban contexts that will enhance urban environmental resilience and guarantee progress towards more sustainable production and consumption patterns together with improvements waste recovery and recovered materials use. Urban_Wins will define a data set, based on material flow indicators, capable of supporting and orienting decision making processes for urban waste prevention and management. Knowledge of the factors that influence the metabolism of cities will be improved together with the understanding of how those factors can be transformed in positive drivers of technological, non-technological and governance changes. The information set produced by the consortium will also focus on how a more efficient use of resources and a better management of waste can improve urban quality and citizens welfare, key points for urban stakeholders involvement, both in the planning and implementation of actions. The proposal reunites diverse actors such as cities, research institutes and universities, environmental NGOs, IT&C, technological innovation and waste management companies, professional associations that represent EU regions, sectors and levels of governance. The complex partnership guarantees that advancement in EU research in the field of urban metabolism and waste management strategies is directly linked to stakeholder engagement and mutual learning and contributes to the achievement of resource efficiency and waste management objectives. Urban_Wins analytical tools will be built on the base of datasets and experiences of 24 EU cities from 6 European countries and the Strategic Plans will be tested by 8 EU cities and will encompass regulatory measures, educational initiatives and sector specific actions.

Sketching is at the root of any design activity. In visual design, hand and pencil are still the primary tools used to produce a large variety of initial concepts in a very short time. However, in product and media design the sonic behavior of objects is also of primary importance, as sounds may afford seamless and aesthetically pleasing interactions. But how might one sketch the auditory aspects and sonic behavior of objects, in the early stages of the design process? Non-verbal sounds, more than speech, are naturally and spontaneously used in everyday life to describe and imitate sonic events, often accompanied by manual expressive gestures that complement, qualify, or emphasize them. The SkAT-VG project aims at enabling designers to use their voice and hands, directly, to sketch the auditory aspects of an object, thereby making it easier to exploit the functional and aesthetic possibilities of sound. The core of this framework is a system able to interpret users intentions trough gestures and vocalizations, to select appropriate sound synthesis modules, and to enable iterative refinement and sharing, as it is commonly done with drawn sketches in the early stages of the design process. To reach its goal, the SkAT-VG project is based on an original mixture of complementary expertise: voice production, gesture analysis, cognitive psychology, machine learning, interaction design, and audio application development. The project tasks include case studies of how people naturally use vocalizations and gestures to communicate sounds, evaluation of current practices of sound designers, basic studies of sound identification trough vocalizations and gestural production, gesture analysis and machine learning, and development of the sketching tools.

The subject of this paper is the plate composed of two identical layers connected to each other in a discontinuous way, i.e. via discontinuous elements (connectors). This paper presents a model that describes the mechanical behavior of this plate by a system of exact, analytical (explicit) equations. The discrete distribution of discontinuous connectors is replaced by a fictitious continuous medium (interlayer). Accordingly, the plate is modeled as an equivalent three-layered plate: Two outer layers and a connecting inner interlayer. In order to obtain a fast and easy to use tool, something that is necessary for an analytical model to be chosen over finite elements and empirical formulas, modeling process is developed within the framework of two-dimensional elasticity. In so doing, the model also represents a means for attaining full comprehension of the mechanical phenomena that are involved, something that neither three-dimensional elasticity nor finite elements and empirical formulas can attain. The transition from three to two-dimensional behavior is obtained by relating the normal stress in the direction transverse to the plate to the distortion in the interlayer. The two-dimensional behavior is governed using kinematic and force assumptions that do not impose appreciable constraints on the stress-strain state and structural behavior. Starting from these assumptions, the paper develops the relationships between displacements and interface stresses, for both continuous and discontinuous connection. The latter relationships, which are used in this model, and the former relationships, which were used in a previously presented model, are discussed and compared to each other. The subsequent sections of the paper describe the model and present some real case applications of discontinuously-connected layered plate. © 2012 Elsevier Ltd. All rights reserved.

The subject of this paper is the plate composed of two relatively stiff outer layers (skins) and a more compliant inner layer (soft interlayer, called core), i.e., three-layered (sandwich) plate. This system may represent composite and laminated plates, e.g., sandwich panels and decks. This paper presents a model that describes the behavior of three-layered plate by a system of exact analytical (explicit) equations, derived from the Kirchhoff-Love plate assumptions. Accordingly, this system of equations corresponds to the Kirchhoff-Love equation of the plate. The pie-chart of research on sandwiches allots only a slight slice to analytical modeling, while it allots the largest slice to approximate prediction methods. In particular, the three-layered plate lacked the two-dimensional governing equations. Empirical or semi-empirical formulations, finite element models, a priori formulas based on simplified or rough theories may represent more accessible research topics; however, they suffer from high layer-to-interlayer stiffness ratios, which impinge on their results. Thus, these approximate prediction methods provide unsatisfactory results for the continuously increasing ratios that the industry is developing, and will be developing, to increase ever more the stiffness-to-density and strength-to-density ratios of the sandwiches. Conversely, this model, whose formulation is exact, does not suffer whatsoever from high skin-to-core elastic modulus ratios, and therefore it is specifically dedicated to modern, advanced, and innovative sandwich plates. To apply this exact model is less time consuming than to generate any finite element mesh or to apply any approximate method. Consequently, approximate methods become completely unnecessary for the three-layered plates that comply with Kirchhoff-Love plate assumptions. On the contrary, for the three-layered plates that do not comply with these assumptions, the finite element models continue to represent a viable means, provided that beforehand their reliability is checked and their free parameters are calibrated. To facilitate check and calibration, exact results from the model are provided in the paper, which finite element results can be compared to. © 2012 Elsevier Ltd. All rights reserved.

This study shows a procedure for the identification of the mechanical characteristics and dynamic parameters of glass fiber-reinforced polymer (FRP) pultruded elements. The matching between analytical model and experimentally acquired modal and natural frequency data is used to investigate the homogeneity of materials (resin and fibers) and the mechanical characteristics variation for pultruded profile with different cross sections, also in presence of induced damage. The experimental results are given primacy, and then the model must be modified by trial and error methodologies of model updating approach. This work depicts the sensitivity analysis based FE model updating procedure and its application to mechanical characteristics and damage assessment of different GFRP members from modal parameters. The accuracy analysis, that relies upon the relative confidence between the results (exp. and analytical) features a FE model of pultruded composite profiles with orthotropic behavior. The same structures were subjected to damage and their identification is based on dynamic response through the curvature mode shapes. This approach allows to know the location and size of damage, the change in dynamic characteristics and thus the decrease in strength and stiffness. The damage identification was carried out also with FE analysis by updating the undamaged beam model. © 2012 Elsevier Ltd.

This paper is focused on laminated glass plate designed with the "sacrificial ply" concept: The glass layer that collects the live loads is considered as broken (i.e., it is not considered), independently of whether or not it is fractured. Accordingly, the load-bearing system is composed of: Heath-strengthened (or annealed) glass layer, plus interlayer, plus toughened (tempered, or chemically-strengthened) glass layer. Hence, the laminated glass plate is hybrid.The first part of the paper derives the constitutive law of the interlayer materials that belong to the latest generation. Then, the behavior of the laminated glass plate is predicted by using this new constitutive law in lieu of the constitutive law of traditional interlayer materials, and the results are analyzed.The second part discusses the results of a theoretical analysis conducted on products available on the architectural marketplace that encompass glass structural applications. These results prove that the ultimate load is dictated by the toughened glass only if the stiffness of the interlayer surpasses a critical value; otherwise, it is dictated by the less resistant glass. However, the critical value is very high. Moreover, the results prove that assessment cannot use practical or simplified expressions (e.g., effective thickness), since these expressions provide the maximum stress in the plate but not in each layer. © 2013.


This paper reports field test results to determine the dynamic behavior of a large all-GFRP space-reticular structure. The first experimental results are illustrated in the frame of a wider research aimed to study the dynamic and static performance of an all-GFRP structure built in L'Aquila (Italy), i.e. a temporary shelter to an ancient church collapsed after the earthquake of 6th of April 2009. Free vibrations were given to the structure with an instrumented hammer and recorded by a laser vibrometer. This kind of test gives the possibility to deduce some strategic information upon structural performance in the field of dynamic identification without invasive tests. In the detail the experimental data of the fundamental frequency and period and damping coefficient are here presented, together with displacements deduced. A comparison to a finite element analysis and closed form solutions suitable to structural vibration analysis allows first final considerations in the field of all-GFRP structure to be done. © 2011 Elsevier Ltd.


A programme of structural assessment and control is currently in progress at Palazzo Ducale in Venice, to evaluate the state of preservation of the two external Medieval façades. A long-term monitoring system of mono-directional accelerometers was set up to investigate the dynamic out-of-plane behaviour of the south façade along a vertical section. A type of action that could be taken as ordinary, involving frequencies in the range of 60-80. Hz, was identified during the first months of activity; the response to this kind of dynamic stress allowed a reliable evaluation of the dissipation properties of the structure. As well, the response to an extraordinary-type event, i.e. an earthquake, could be measured during the monitoring period. The first numeric elaborations based on experimental data are presented, i.e. a first calibration of the model of the south façade, aimed to establish the boundary conditions of the model (i.e. translational stiffness of connections to roof and floor structures), by means of spectral analysis with input experimental response spectrum. The good performance of this preliminary numerical model could finally be assessed. © 2012 Elsevier Ltd.

The subject of this paper is the plate composed of two identical isotropic outer layers and a more compliant inner interlayer, perfectly connected to one another at the interface (three-layered plate). This paper presents a model that describes the behavior of this plate by a system of exact analytical (explicit) equations. An analytical model is preferred over finite element models and simplified formulas if it is fast and easy-to-use. Thus, modeling has been developed within the framework of two-dimensional elasticity, instead of three. In so doing, the model also represents a means for attaining full comprehension of the involved phenomena, something that neither three-dimensional elasticity nor finite element models and simplified formulas can attain. The two-dimensional behavior is governed here by using assumptions that do not impose constraints on the behavior. Starting from these assumptions, the paper illustrates the relationships between displacements and interface stresses. The subsequent sections of the paper describe the model and present some real case applications. The contribution of this paper is to consider both the shear modulus and the elastic modulus of the interlayer. Thus, this model applies to three-layered plates with any interlayer, whether utterly compliant or relatively stiff. Conversely, the previous exact analytical models assumed zero elastic modulus, and hence they applied to utterly compliant interlayers only. Hence, not only does the new model predict the exact behavior of plates that the former analytical models described only approximately, but this model may also be used as a benchmark for finite element models, which cannot assign zero value to the elasticity modulus of the interlayer together with the actual shear modulus. © 2013 Elsevier Ltd.

INCOMMON will be the first study to systematically analyse the field of performing arts as resulting from the practice of commonality both theorized and experienced over the 1960s and the 1970s.In particular, the project is aimed to study the history of the laboratory Italy as the place where artistic counterculture expressed by performing arts arose in a milieu characterized by a profound relation between philosophy, politics, and revolutionary practices. The overall objectives of INCOMMON are i) to study, collect and contextualize those encounters between theatre, music, visual arts, cinema and video art that assumed the form of performances, especially those created as collaborations between artists; ii) to apply the concept of will-to-the-common to the art field of the counterculture; iii) to underline the significance of artistic communities in the local and international scene; iv) to create a digital archive of the performances of the Italian artists of the period. The project will connect historical, philosophical and artistic debates to those in other sciences, sociology and in particular Social Network Theory,in order to reveal significant structures of meanings in the artistic community and to reveal the peculiar characteristics of shared creative processes.The methodology that will be developed is meant 1) to produce new ways of modelling the knowledge and interpretation of performing arts and 2) to create an innovative form of digital archive visualization, where rich interfaces will sustain and improve the understanding of the context and relationships analysed. INCOMMON will produce a comprehensive approach, oriented toward collection, digitization, restoration and dissemination of direct documentation and related materials of the Italian performing arts production of the great creative, political, existential wave of the counterculture, preserving and making accessible a patrimony that otherwise will continue to be lost to future generations.
