Reverse Electrodialysis with seawater and concentrated brine: a comprehensive process modelling
2012
A multi-physics modelling tool for Reverse Electrodialysis
2015
In this work, a multi-physics modelling approach has been developed for the RED process.
Process modelling of a novel acid-base flow battery based on bipolar-membranes
2021
The storage of electrical energy is crucial for a deeper penetration of renewable energies with intermittent nature, e.g. solar and wind energy. The Acid/Base Flow Battery (AB-FB) is a novel, sustainable, environmental-friendly storage technology with high energy density of the electrolyte solutions. The process is based on reversible electrodialytic techniques with bipolar membranes, which convert the electrical energy in the chemical energy associated to pH gradients and vice versa. The charge phase is a bipolar membrane electrodialysis process, while the discharge phase is a bipolar membrane reverse electrodialysis process. The stack consists of several repetitive units, called triplets,…
REAPOWER – USE OF DESALINATION BRINE FOR POWER PRODUCTION THROUGH REVERSE ELECTRODIALYSIS
2015
Salinity gradient power (SGP) represents a viable renewable energy source associated with the mixing of two solutions of different salinities. Reverse electrodialysis (SGP-RE or RED) is a promising technology to exploit this energy source and directly generate electricity. However, although the principle of this technology is well known since several years, further R&D efforts are still necessary in order to explore the real potential of the SGP-RE process. With this regard, the aim of the REAPower project ( [GRAPHICS] ) is the development of an innovative system for power production by SGP-RE process, using sea (or brackish) water as a diluted solution and brine as a concentrate. The use o…

Reverse electrodialysis: advanced modelling and scale-up
A Norm-Governed Holonic Multi-agent System Metamodel
2013
Modeling and designing systems that require a high level of coordination, control and automation is a very difficult task. The problem is the lack of design processes able to cover all the features these systems present. This paper presents an extension of the ASPECS metamodel for supporting organizational and normative principles and it allows to define models not only from an holonic agent viewpoint but also from a normative organization perspective. Moreover, our work emphasizes and makes it explicit the norms that regulate the structural, behavioral and finally adaptive aspect of an organizational system. The extended metamodel was experimented creating a Virtual Enterprise model for th…
Fast Volumetric Reconstruction of Human Body through Superquadrics
2013
This paper describes a technique to reconstruct the volumes of the human body. For this purpose, are introduced mathematical objects able to represent 3d shapes, called super quadrics. These objects are positioned in the space according the captures made by a Microsoft Kinect device and are composed to represent the volumes of the human body. The employment of quaternions provides a relevant speedup for the rotation of the volumes and allows to follow the human movements in real time and reduced computational cost.
Dallo scavo archeologico alla riprogettazione virtuale di un edificio: La chiesa a doppia abside del casale di Quattro Macine, Giuggianello (Lecce)
2003
The increasingly widespread use of computational technologies in the archaeological field it has opened up new possibilities of research thanks to the passage of information technology from simple support for "management and documentation" of data as a tool for the "production and analysis" of data themselves. Nowadays, having new software from computer-aided architectural design (Computer Aided Design) it is possible for the archaeologist to use the computer to realize a virtual reconstruction intended as a tool of archaeological analysis of an artifact building, retracing all the individual steps of the activity constructive up to the original architectural project. To proceed in this wor…
Indagini multidisciplinari e ricostruzione virtuale: il caso di studio del Teatro Nord di Hierapolis di Frigia (Turchia)
2018
The contribution concerns the multidisciplinary research conducted on the North Theatre of Hierapolis in Phrygia (south-western Turkey), built in the 2nd cent. AD and collapsed because of an earthquake in the third quarter of the 4th cent. AD. A systematic analysis and topographical survey of the remains of the Theatre were performed, and plan of the building was integrated into the digital archaeological map of the city. These data were combined with those from the geological study of the site (characterized by landslides) and from the geophysical prospecting (magnetometry and GPR) carried out in the area of the scaena and in the space between the Theatre and the North Agora. The integrati…
