A multiple layered functional data model to support multiple representations and interoperability of GIS

2001

This paper presents a multi-layered functional data model to support multiple representation and information sharing among distributed spatial information systems. The key idea is that a geographical space (foe example an urban space) can be viewed as a set of abstract spatial functionalities on which different application classes can be derived to manipulate objects of the same geographical space and share the same abstract generic functionalities. The object classes define multiple views or representations of a domain. For example in urban management, transportation systems, water supply and sewage systems applications can share generic network functionalities defined by graph treversal o…

Charge loss correction in CZT pixel detectors at low and high fluxes: analysis of positive and negative pulses

2018

Charge losses are typical drawbacks in cadmium–zinc–telluride (CZT) pixel detectors. The effects of these phenomena are strongly related to the interaction point of the photons and are more severe for photon interactions at the inter-pixel gap and near the pixelated anode. In this work, we present some original techniques able to correct charge losses in pixelated CZT detectors at both low and high fluxes. The height, the shape and the arrival time of collected- and induced-charge pulses with both positive and negative polarities are analysed to recover charge losses after the application of charge sharing addition (CSA). Sub-millimetre CZT pixel detectors, fabricated by different manufactu…

Connection between Design and Nature Reflections and Projects for the future of the Planet

2022

Humanity’s delayed reaction to the consequences of the climate crisis is the result of multiple interests and strategies caused by denialist policies and piloted information. It is also true, however, that there is a strictly cultural responsibility, in the form of a lack of dialogue between sources of knowledge. Restoring the balance between humanity and nature is the most important issue that contemporary design must address. Design has the task of highlighting objects and strategies in re-establishing the relationship between Man and the context in which he lives by re-integrating the social and natural ecosystems. In this context, thanks to the evolution of natural sciences and technolo…

Enabling peer-to-peer User-Preference-Aware Energy Sharing Through Reinforcement Learning

2020

Renewable, heterogeneous and distributed energy resources are the future of power systems, as envisioned by the recent paradigm of Virtual Power Plants (VPPs). Residential electricity generation, e.g., through photovoltaic panels, plays a fundamental role in this paradigm, where users are able to participate in an energy sharing system and exchange energy resources among each other. In this work, we study energy sharing systems and, differently from previous approaches, we consider realistic user behaviors by taking into account the user preferences and level of engagement in the energy trades. We formulate the problem of matching energy resources while contemplating the user behavior as a …

InspirationWall

2015

Collaborative idea generation leverages social interactions and knowledge sharing to spark diverse associations and produce creative ideas. Information exploration systems expand the current context by suggesting novel but related concepts. In this paper we introduce InspirationWall, an unobtrusive display that leverages speech recognition and information exploration to enhance an ongoing idea generation session with automatically retrieved concepts that relate to the conversation. We evaluated the system in six idea generation sessions of 20 minutes with small groups of two people. Preliminary results suggest that InspirationWall contrasts the decay of idea productivity over time and can t…

A Reinforcement Learning Approach for User Preference-aware Energy Sharing Systems

2021

Energy Sharing Systems (ESS) are envisioned to be the future of power systems. In these systems, consumers equipped with renewable energy generation capabilities are able to participate in an energy market to sell their energy. This paper proposes an ESS that, differently from previous works, takes into account the consumers’ preference, engagement, and bounded rationality. The problem of maximizing the energy exchange while considering such user modeling is formulated and shown to be NP-Hard. To learn the user behavior, two heuristics are proposed: 1) a Reinforcement Learning-based algorithm, which provides a bounded regret and 2) a more computationally efficient heuristic, named BPT- ${K}…

REPUTATION MANAGEMENT ALGORITHMS IN DISTRIBUTED APPLICATIONS

2020

Nowadays, several distributed systems and applications rely on interactions between unknown agents that cooperate in order to exchange resources and services. The distributed nature of these systems, and the consequent lack of a single centralized point of control, let agents to adopt selfish and malicious behaviors in order to maximize their own utility. To address such issue, many applications rely on Reputation Management Systems (RMSs) to estimate the future behavior of unknown agents before establishing actual interactions. The relevance of these systems is even greater if the malicious or selfish behavior exhibited by a few agents may reduce the utility perceived by cooperative agents…

The Role of Sharing Mobility in Contemporary Cities. Legal, Social and Environmental Issues

2020

The emergence of sharing mobility is having a profound impact on urban landscapes. In fact, it is deeply affecting the traditional organization of local services by calling into question how urban transportation is planned, and by redesigning city spaces. Further, by connecting people to shared assets, services or both, sharing mobility is poised to facilitate the more efficient use of underutilized resources, becoming a powerful tool for economic growth and social inclusion, while also contributing to sustainability. That being said, the economic, social and spatial impacts of sharing mobility have not been sufficiently investigated, and so far, the evidence is mixed. From a normative stan…

Information providers e information sharing mechanisms nel mercato creditizio italiano.

2015

Il presente lavoro esamina i principali casi aziendali di information providers e sistemi di information sharing operanti nel mercato creditizio italiano, con una prospettiva di analisi prettamente economico-aziendale. Sono analizzati i modelli di business dei primi 5 operatori italiani: Cerved, Crif, Infocamere, Experian, Euler Hermes Siac. Sarà, inoltre, preso in esame il sistema di condivisione di informazioni di natura pubblica, gestito dalla Banca d’Italia, che ha un ruolo di rilievo nel sistema creditizio italiano. Quello che emerge dall’analisi è un quadro molto variegato dei sistemi di informazione creditizia operanti in Italia in quanto, accanto al tradizionale business dell’inform…
