L'impiego dei polimeri nel design, da materiali di imitazione a protagonisti
No full textI primi oggetti realizzati alla metà dell'800 con i polimeri semi-sintetici di prima generazione per farsi accettare dal mercato imitavano i materiali naturali come l'ambra, il corno, la tartaruga. Lo scritto fornisce una sintetica panoramica dell'evoluzione delle plastiche nell'ambito del design, dal loro apparire fino all'estetica degli oggetti contemporanei. Il testo è la sintesi di un intervento tenuto da Cecilia Cecchini nell'ambito del corso interdisciplinare "La plastica nell'atre e per l'arte" promosso dalla Fondazione Plart in collaborazione con numerosi enti di ricerca e università. L'autrice è vice presidente del Corso
From gridmap-file to VOMS: managing Authorization in a Grid environment
No full textFrom gridmap-file to VOMS: managing authorization in a Grid environment R. Alfieri, R. Cecchini, V. Ciaschini, L. dell’Agnellod, A. Frohner, K. Lorentey, F. Spataro Future Generation Computer Systems 21 (2005) 549–558 doi:10.1016/j.future.2004.10.006 Abstract Grids are potentially composed of several thousands of users from different institutions sharing their computing resources (or using resources provided by third parties). Controlling access to these resources is a difficult problem, as it depends on the policies of the organizations the users belong to and of the resource owners. Moreover, a simple authorization implementation, based on a direct user registration on the resources, is not applicable to a large scale environment. In this paper, we describe the solution to this problem developed in the framework of the European DataGrid [M. Draoli, G. Mascari, R. Piccinelli, Project Presentation, DataGrid-11-NOT-0103- 1] and DataTAG [http://www.datatag.org/] projects: the Virtual Organization Membership Service (VOMS) [R. Alfieri, et al., Managing Dynamic User Communities in a Grid of Autonomous Resources, TUBT005, in: Proceedings of the CHEP 2003, 2003]. VOMS allows a fine grained control of the use of the resources both to the users’ organizations and to the resource owners
A 3d platform for energy data visualization of building assets
No full textWith an exemplary role, the improvement of energy efficiency in public buildings is
in the forefront of the European policies for smart and sustainable growth. However, very often
the sector is characterized by large and old constructions that may also be marked by historical
and cultural value and whose energy consumption is hard to be reduced, due to specific
constraints. In order to operate in this field, the definition of a solid knowledge framework on
the built environment appears to be the only viable starting point. Therefore, the analysis of the
delicate balance between conservation and transformation should be investigated with a multiscalar
approach able to move from the city to the building elements. For this reason, it is
extremely important to provide tools for monitoring and analysing the energy behaviour of the
public building stocks to those actors that are involved in their management. The research here
presented proposes a workflow to implement a web platform based on a three-dimensional GIS
(Geographic Information System) interoperable with BIM (Building Information Modeling) and
able to store, handle and display information on building assets and their energy consumption.
With the aim of defining a repeatable model, the process starts from easily retrievable data on
the built environment and uses standard data models and classification systems. The threedimensional
model is built in a semi-automated way from the combination of the twodimensional
GIS cartography of the municipality and from the point cloud resulting from a
LiDAR (Light Detection And Ranging) national survey campaign. The set of thermal properties
and energy data can be retrieved from the energy performance certificate of the buildings. In
order to test and validate the process, an application on the building stock owned by the
University of Pavia (Italy) is presented. Nine complexes distribute inside the historical centre of
the city and heterogeneously dated from the X to the XX century are considered. After the
definition of the model and its representation inside the web environment, an example of use is
displayed with reference to a comparative energy analysis of different buildings
Tridimensional computed tomography (TC 3D) in plastics: First personal experience
No full textTraditional diagnosis of craniofacial malformations is based on standard radiography, cephalometry and computed tomography. Tridimensional reconstructions (TC 3D) have been useful for a better clinical and therapeutic approach to the complex craniocephalic pathology. This study shows first experiences of use of 3D Siemens programme on Somatom HiQ in the Radiodiagnostic Department of Policlinico S. Matteo of Pavia. Pros and cons of such method in diagnostic and surgical planning of some traumatic, neoplastic and malformative pathologies are reported and discussed. Cephalic dyssymetries are more easily studied because of a better sight of skeletal and soft parts alterations. Better knowledge of relations between skeleton and adjoining soft parts and more accurate cephalometric mensurations, even considering prosthetic treatment, make preoperative planning easy. Limits of such a method are: necessity of sedation for pediatric patients, in order to get complete immobility; exposition to a relative high dose of radiations and some technical artifacts
