H-BIM and web-database to deal with the loss of information due to catastrophic events - The digital reconstruction of San Salvatore's Church in Campi di Norcia (Italy)
No full textNowadays , we are able to produce geometric models of historical buildings at different scales of detail, using photos and measurements. This is true when you are observing something that is still under your eyes. We are faced more and more with lack of preservation actions and maintenance activities, policies framed without foresight, unexpected natural events, etc., that are forcing professionals and researchers to operate without usual data. In such cases, we need a consistent repository to collect and distribute data to produce information.Furthermore, we need to "give intelligence" to these repositories, in order to query them with respect to geometrical instances, topological issues, historical features, etc. This last aspect, (archives and databases connected with geometrical aspects), lead our digital model to a new dimension, the informative one (where spatial, temporal, historical and building parameters work together), that should always characterize speculative actions towards the constitution of a wealth of knowledge. We need to work on the efficiency of the process to reach effective methodologies of survey
Systemic Design approach in policy making for sustainable territorial development
No full textThe era of transition that we are experiencing need a radical change also in the structure of society. This must be reflected in political commitment to find a new structure of rules able to facilitate participatory processes and to support initiatives than can bring social innovation. For this reason, cooperation between design, technology, economics and sociology is fundamental. As the society is currently undergoing a profound change it is necessary that the policies outcome from a commitment arising from a multidisciplinary team. An example of coordinated work between universities, local authorities, government offices, associations, public bodies is the RETRACE project (Systemic Approach for Transition towards a Circular Economy). RETRACE's aim is to drive EU policies applying the SDA (Systemic Design Approach), which means by using the output of a system as an input of another system. Applying CE to define a strategy in order to look forward to a regional development allows to reach fundamental social benefits: "[...] the circular economy will offer a number of societal benefits for European countries not least in terms of carbon emissions reductions and job gains" (Wijkman, Skanberg, 2015)
Digital interactive Mollino. A Collection of 3D Models from Carlo Mollino Design Drawings
No full textThis paper presents a research aimed to create a collection of digital interactive models of Carlo Mollino's designs. Mollino's archive contains hundreds and hundreds of drawings, photographs, writings and other materials, related to his design activity in the fields of architecture and furniture design. Only few architectural designs were realized, the others remained ‘on paper'. Digital modeling is a way to give a new life to this important archival heritage allowing new scientific discoveries and interpretations about his masterpieces. The collection has been set to rigorous scientific assumptions in order to offer to scholars some validated base materials and interaction instruments, in order to facilitate personal surveys, interpretations and sharing of knowledge

No full textCurrent Efforts to Make Perovskite Solar Cells Industrially Viable
No full textPhotovoltaic (PV) technology has evolved rapidly in the past few decades and now encompasses a large variety of materials and device structures. A perovskite solar cell (PSC) is a photovoltaic device which includes a perovskite-structured compound, most commonly a hybrid organic-inorganic lead halide-based material, as the light-harvesting active layer. These devices are cheap to produce and simple to manufacture at a laboratory level. Solar cell efficiencies of devices using these materials have increased from 3.8% in 2009 to 22.1% in early 2016, making this the fastest-advancing solar technology to date. Therefore, it is clear that - with the potential of achieving even higher efficiencies - PSCs have become commercially attractive, and a few issues should be fixed soon. A key aspect to be taken into account in any PV technology is the operational durability of these systems in outdoor conditions. Clearly, loss of performance during operation represents a significant drawback and limitation for their commercialization. In this context, the large compositional flexibility of polymeric materials as well as their proven easy processability may be of great help in imparting improved durability to PV systems. We show that rapid light-induced free-radical polymerization at ambient temperature produces multifunctional fluorinated photopolymer coatings that confer luminescent and easy-cleaning features on the front-side of the devices, while concurrently forming a strongly hydrophobic barrier toward environmental moisture on the back contact side. The luminescent photopolymers re-emit ultraviolet light in the visible range, boosting perovskite solar cells efficiency to nearly 19% under standard illumination. Coated devices reproducibly retain their full functional performance during prolonged operation, even after a series of severe aging tests carried out for more than 6 months. The industrialization of PSCs also requires the development of processes different with respect to those used in academic laboratories. For example, lab-scale PSC preparation is based on spin-coating technique, that is not transferable on a large scale. In this contribution we will also show the alternative strategies proposed by the scientific community to fabricate solar cells components on large areas
Experimental and Numerical Assessment of Multi-Event Injection Strategies in a Solenoid Common-Rail Injector
No full textNowadays, injection rate shaping and multi-pilot events can help to improve fuel efficiency, combustion noise and pollutant emissions in diesel engine, providing high flexibility in the shape of the injection that allows combustion process control. Different strategies can be used in order to obtain the required flexibility in the rate, such as very close pilot injections with almost zero Dwell Time or boot shaped injections with optional pilot injections. Modern Common-Rail Fuel Injection Systems (FIS) should be able to provide these innovative patterns to control the combustion phases intensity for optimal tradeoff between fuel consumption and emission levels.In this work, a 1D-CFD model in GT-SUITE of a solenoid ballistic Common-Rail injector was firstly refined respect to the previous work [1] and then it was validated against an extensive experimental dataset of single injections, standard double pilot and multi-pilot injection patterns (up to 4 pilot events) with almost zero dwell time between two consecutive injection events. The experimental hydraulic test data used to validate the one-dimensional model were obtained by means of the UniPG Injection Analyzer based on the Zeuch's method.The comparison between the experimental and simulated volumetric injection rates showed a more than satisfactory accuracy of the model in predicting the actual behavior of the ballistic injector for all the injection patterns tested, even for relatively complex injector command strategies, characterized by reduced Dwell Time values between consecutive injection events
Decision Scheme for Lighting Controls in Non-Residential Buildings
No full textThis report offers guidelines in order to balance lighting quality, user comfort and energy efficiency in lighting controls solutions for lighting in non-residential buildings (i.e. for commercial, institutional and industrial buildings). It provides a decision scheme with a focus on the user requirements (visual comfort, performance, personal control) to determine the most applicable control solution, including the consequences for possible savings. In this, it assumes that there are no technological or financial hurdles. The decision scheme identifies 16 possible control strategies, for both daylight and electric lighting, and provides guidance for which strategy would be most effective in each of the 12 cases defined by space usage and occupancy
Seismic reliability of steel structures isolated by fps
No full textThis paper evaluates the seismic reliability of steel structures, isolated using friction pendulum system, subjected to artificial earthquake ground motions. The behaviour of the steel superstructure is assumed linear whereas the FPS devices are described by adopting a velocity-dependent model. Both the seismic input, modelled as a non stationary random processes, and the friction coefficient at large velocity are considered as random variables through appropriate probability density functions. Incremental dynamic analyses are developed and then the fragility curves related to both superstructure and isolation level are evaluated. Finally, considering the seismic hazard curve related to a site near Sant'Angelo dei Lombardi (Italy), the seismic reliability of the overall steel system is evaluated
