Activity-Centered Design: An Appropriation Issue
2011
When designing workplace computer systems one must take human activity into account. It has become standard practice to approach this issue through user-centered design. The aim of this paper is to stimulate thought on activity-centered design and to propose the concept of appropriation as a fundamental principle of this design approach. This orientation aims to take into consideration the constituent function of tools during conception. We will take the design of computer systems dedicated to customer relations as an example.
Using tools effectively despite defective hand posture: A single-case study.
2019
Apraxia, a cognitive disorder of motor control, can severely impair transitive actions (object-related) and may lead to action errors (e.g., rubbing a hammer on a nail instead of pounding it) and hand posture errors (e.g., grasping a tool in a wrong way). Here, we report a rare observation of a left-handed patient, left-lateralized for language, who developed a severe apraxia following a right brain lesion. Interestingly the patient showed a significant number of hand posture errors, while she perfectly demonstrated the actual use of tools. This case stressed the predictions made by the current theories of tool use. According to the manipulation-based approach, the hand posture errors shoul…
Branch-Price-and-Cut for the Soft-Clustered Capacitated Arc-Routing Problem
2021
The soft-clustered capacitated arc-routing problem (SoftCluCARP) is a variant of the classical capacitated arc-routing problem. The only additional constraint is that the set of required edges, that is, the streets to be serviced, is partitioned into clusters, and feasible routes must respect the soft-cluster constraint, that is, all required edges of the same cluster must be served by the same vehicle. In this article, we design an effective branch-price-and-cut algorithm for the exact solution of the SoftCluCARP. Its new components are a metaheuristic and branch-and-cut-based solvers for the solution of the column-generation subproblem, which is a profitable rural clustered postman tour …
A comparison of two different formulations for Arc Routing Problems on Mixed graphs
2006
[EN] Arc routing problems on mixed graphs have been modelled in the literature either using just one variable per edge or associating to each edge two variables, each one representing its traversal in the corresponding direction. In this paper, and using the mixed general routing problem as an example, we compare theoretical and computationally both formulations as well as the lower bounds obtained from them using Linear Programming based methods. Extensive computational experiments, including some big and newly generated random instances, are presented.

Towards the Preservation and Dissemination of Historical Silk Weaving Techniques in the Digital Era
2019
Historical weaving techniques have evolved in time and space giving as result more or less fabrics with different aesthetical characteristics. These techniques were transferred along the main silk production centers, thanks to the European Silk Road and creating a common European Frame on themes and techniques. These had made it complicated to determine whether a fabric corresponds to one century or another. Moreover, in order to understand their creation, it is necessary to determine the number of weaves and interlacements that each textile has, therefore, mathematical models can be extracted from these layers. In this sense, three dimensional (3D) virtual representations of the internal s…
Persistenza della thòlos nell’architettura contemporanea
2020
La thòlos è una costruzione che può essere assunta come un inizio dell’architettura e che definisce principi che stanno oltre la storia e l’archeologia: rappresenta un archetipo legato al mondo litico, proveniente dall’oriente e diffuso sin dall’età greco-arcaica in tutto il Mediterraneo. Custodisce memorie di epoche mitiche e forme che affiorano con continuità nell’architettura, attraversa la storia e persiste nella modernità soprattutto negli spazi di culto e celebrativi. Lo spazio della thòlos consente di riprendere nel progetto contemporaneo alcuni temi i cui esiti conducono ad una architettura che è in antitesi alla continuità visiva interno-esterno e all’assenza di confini, che all’in…
A bottom-up harmonized energy-environmental models for europe (BOHEEME): A case study on the thermal insulation of the EU-28 building stock
2021
Abstract The paper presents a methodological approach, called “BOttom-up Harmonized Energy-Environmental Models for Europe” (BOHEEME), that combines bottom-up modeling, energy dynamic simulation, and life cycle assessment for evaluating and comparing the energy and environmental effects of different renovation strategies of the residential EU building stocks, from micro to the macro level. The study defines 672 building models representative of the residential EU-28 building stocks built before 2010, called archetypes, and the improvement of their envelope, applying different insulation materials from a traditional one to bio-based materials and studying their environmental effects via LCA.…
SUITE D'AUTORE: ARCHITETTURA, DESIGN E TECNOLOGIA PER UNA MODERNA CULTURA DELL'OSPITALITA'
2008
Per comprendere a fondo l’insieme delle modificazioni che hanno interessato il territorio antropizzato nel corso dei secoli, occorre anche valutare quelle specifiche architetture che sono destinate all’ospitalità; in particolare occorre considerare le loro peculiarità concettuali, spaziali, funzionali e tecnologiche, che si sono lentamente modificate per garantire il raggiungimento di un alto livello qualitativo per l’accoglienza. Nel presente volume, l’esigenza di indagare nel campo dell’accoglienza e di ritrovare quei caratteri della ricerca scientifica che ne definiscono la storia, la tecnica, i materiali e non di meno le emozioni, diviene l’obiettivo che l’Autore vuole raggiungere. Il v…
Mediterranean Great Conversation
2015
The exit from the Mediterranean emergency requires rethinking its identity in a new perspective. This means recognizing its legitimate role as a “Great Sea in Between”, as a cultural interface able to connect all the citizens that address to it, in everyday life and as individuals, involving them in a real “great conversation” based on the design disciplines. Design, Brand, Visual Identity, Packaging, Social Media, Fashion, Food, Architecture, Music may be powerful antidotes to the immobility of those who mourn a lost Mediterranean harmony and also a viable alternative to the ethnic closure led by the proponents of the Clash of Civilizations.
