A novel forklift solution for promoting occupational re-integration of disabled people22nd Mediterranean Conference on Control and Automation
No full textA study on the employment of disabled people as forklift truck drivers for cargo handling operations is here presented. The work focused on the design of a customized forklift and the development of a novel lift machine as aid for people with paraplegia. Results of a market research about the usefulness of such a system is presented and a novel robotic modified forklift simulator has been realized and described. A final testing session is introduced to assess the performances of disabled and non-disabled people during typical logistic task executions

No full textNel campo della realtà virtuale e della computer grafica spesso si ha a che fare con modelli tridimensionali di grandi dimensioni. Nonostante i miglioramenti dei dispositivi hardware avvenuti in questi ultimi anni, quando l'applicazione utilizza modelli composti da milioni di poligoni, non sempre è possibile raggiungere un sufficiente grado di interattività.
A tale scopo sono state sviluppate numerose tecniche che ottimizzano e velocizzano il processo di visualizzazione. In particolare, il lavoro svolto riguarda una tecnica di semplificazione di mesh poligonali ed il suo impiego per la generazione di livelli di dettaglio (LOD). Inoltre è stata implementata una tecnica di compressione di mesh di triangoli per una gestione ed archiviazione più efficiente di modelli di grandi dimensioni
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
A Stereo-Panoramic Telepresence System for Construction Machines
No full textWorking machines in construction sites or emergency scenarios can operate in situations that can be dangerous to an operator both
for direct control of the machine or teleoperation in co-presence. Remote operation has been typically hindered by limited sense
of presence of the operator in the remote of the environment to due the reduced field of view of cameras. Starting from these
considerations we are introducing a novel real-time panoramic telepresence system for construction machines. This system does
allow fully immersive operations in critical scenarios while keeping the operator in a safe location at moderate distance from the
construction site. An omnidirectional stereo vision head mounted over the machine acquires and streams data to the operator with a
streaming technique that focuses on the current direction of site of the operator. According to the motion of the operators head, the
telepresence system will determine the involved cameras to use and the appropriate region of interest in cameras. The operator uses
a head-mounted display to experience the remote site also with the possibility to view digital information overlaid to the remote
scene as a type of augmented reality. The paper addresses the design and architecture of the system starting from the vision system
and then proceeding to the immersive visualizatio
