Strategic Vision of a Euro-Mediterranean Port City: A Case Study of Palermo

2013

Italian harbours assume a decisive role in order to develop a Euro-Mediterranean web for maritime transportation. The geostrategic position of the Italian peninsula can be seen as a logistic platform at the centre of the maritime trades in the Mediterranean area, giving to its port cities the role of gateway of economic flows. The port poles, meant as hubs, are able to attract investments and create economic growth and territorial development through new operative models of urban usage and management. The management policies have to consider the environmental characteristics and distinctive features, respecting the identity of the places as concrete evidence of history, a source of intellec…

Industrial development as discursive change: A case of symbiotic learning

2016

The Eyde Cluster is a network of companies at Agder seeking to enhance sustainabledevelopment through vocational training. A dialogical approach is taken to developing anew discourse, using principles of communicative organisational change. There isdiscussion of a more bottom up approach, in line with Workplace Innovation. The paperargues for balancing formal education and vocational training in a way that createssymbiotic learning.

Il fondamento effimero : seminario residenziale di allestimento urbano e architettura effimera, Tonezza del Cimone, 25-31 Agosto 2018

2019

Tourist places often suffer a fate that sees them seasonally abandoned, so that their image drastically changes over the course of the year, generating gaps that need an identity rather than waiting for the festive mass passing by. Professors, students, teacher assistants collaborated together in a weekly on-site workshop meeting and listening people resident with a bottom-up approach.

Constrained Role Mining

2013

Role Based Access Control (RBAC) is a very popular access control model, for long time investigated and widely deployed in the security architecture of different enterprises. To implement RBAC, roles have to be firstly identified within the considered organization. Usually the process of (automatically) defining the roles in a bottom up way, starting from the permissions assigned to each user, is called {\it role mining}. In literature, the role mining problem has been formally analyzed and several techniques have been proposed in order to obtain a set of valid roles. Recently, the problem of defining different kind of constraints on the number and the size of the roles included in the resu…

Combining Top-down and Bottom-up Visual Saliency for Firearms Localization

2014

Object detection is one of the most challenging issues for computer vision researchers. The analysis of the human visual attention mechanisms can help automatic inspection systems, in order to discard useless information and improving performances and efficiency. In this paper we proposed our attention based method to estimate firearms position in images of people holding firearms. Both top-down and bottom-up mechanisms are involved in our system. The bottom-up analysis is based on a state-of-the-art approach. The top-down analysis is based on the construction of a probabilistic model of the firearms position with respect to the people’s face position. This model has been created by analyzi…

DEMAND Project: An algorithm for the assessment of the prosumers’ flexibility

2020

Demand side aggregation represents an important opportunity for ancillary services provision due to the potential that the coordinated management of distributed resources has on affecting power systems' operation. In this framework, the Aggregator has a main role and takes on different relationships with the other actors of the power system, usually becoming a mediator between the prosumers and the distribution system operator. The DEMAND project introduces a new point of view in demand side aggregation by proposing a new framework where the Aggregator is no more needed and prosumers can share and combine their flexibility in a new aggregation platform called Virtual Aggregation Environment…

DEMAND Project: Bottom-Up Aggregation of Prosumers in Distribution Networks

2018

The paper explains the concept of the DEMAND project, whose aim is to develop a technical framework for allowing a Bottom-Up aggregation of prosumers connected to the distribution grid. Load and generation aggregation is a very current issue given the great potential that the coordinated management of distributed resources has on power systems operation and design. The novelty in DEMAND is the absence of a physical aggregator and the recourse to a virtual aggregation environment (VAE) for allowing the exchange of information among the prosumers in order to provide a service to the DSO. After a general description of the research project, the paper presents the services that the aggregated c…

A Methodology for Exploiting Smart Prosumers’ Flexibility in a Bottom-Up Aggregation Process

2022

The electrical power system is evolving in a way that requires new measures for ensuring its secure and reliable operation. Demand-side aggregation represents one of the more interesting ways to provide ancillary services by the coordinated management of a multitude of different distributed resources. In this framework, aggregators play the main role in ensuring the effectiveness of the coordinated action of the distributed resources, usually becoming mediators in the relation between distribution system operators and smart prosumers. The research project DEMAND recently introduced a new concept in demand-side aggregation by proposing a scheme without a central aggregator where prosumers ca…

The Expansion of English-medium Instruction in the Nordic Countries.Can Top-Down University Language Polices Encourage Bottom-up Disciplinary Literac…

2015

Recently, in the wake of the Bologna Declaration and similar internationalinitiatives, there has been a rapid increase in the number of university courses and programmestaught through the medium of English. Surveys have consistently shown theNordic countries to be at the forefront of this trend towards English-medium instruction(EMI). In this paper, we discuss the introduction of EMI in four Nordic countries (Denmark,Finland, Norway and Sweden). We present the educational setting and the EMIdebate in each of these countries and summarize relevant research findings. We then makesome tentative suggestions for the introduction of EMI in higher education in othercountries. In particular, we are…
