Towards a psychophysical evaluation of a surgical simulator for bone-burring
Get PDFThe CRS4 experimental bone-burr simulator implements visual and haptic effects through the incorporation of a physics-based contact model and patient-specific data. Psychophysical tests demonstrate that, despite its simplified model and its inherent technological constraints, the simulator can articulate material differences, and that its users can learn to associate virtual bone with real bone material. Tests addressed both surface probing and interior drilling task. We also explore a haptic contrast sensitivity function based on the model s two main parameters: an elastic constant and an erosion factor. Both parameters manifest power-law-like sensitivity with respective exponents of around two and three. Further tests may reveal how well simulator users perceive fine differences in bone material, like those encountered while drilling through real volume boundaries.139-14
A Decision Support System based on the SWAT model for the Sardinian Water Authorities
Get PDFSardinian Regional Authorities, such as Assessorato della Difesa dell’Ambiente, have the demanding problem of water management and protection. Targeted to their specific needs they use alternative applications and models for their specific tasks. Black box models, in the past, have been the most commonly used approach to describe the hydrological cycle. Despite their wide use, these models have shown severe limitations to take into account land use and climate changes. Physically based models can make better prediction when different combination of soil and land use, within the basin, have a significant effect on the hydrological cycle. The variety and complexity of alternative environmental problems found in the island, which vary from the impact of the agro-zootechnical to the industrial compartment, have suggested that empirical models are less suitable to predict the environmental dynamics at the catchment’s scale. Regional Authorities enact Regional Directives to enforce different European Directives, and no absolute limits can be drawn to separate their alternative field of application. The Piano di Tutela delle Acque Regional Directives aim to enforce water policy in terms of definition on where and how water resources must be used and what water protection actions need to be taken to improve water quality of rivers, lagoons, groundwater, lakes etc.. In this context, the hydrological physically based SWAT model has been chosen and applied to estimate both the water balance of the main catchments of the island and the impact of land management practices on downstream water bodies. The performance of the model has been evaluated on several stream flow monitoring gages against registered data.The study has been partially funded by the Sardinian Regional Authorities.369-37
La valorizzazione delle produzioni di pane tipico Coccoi e Moddizzosu. Relazione conclusiva
Get PDFNel corso dell’indagine, sono state condotte delle prove per la messa a punto di uno starter microbico. Sia per il Coccoi che per il Moddizzosu è stato, quindi, definito il protocollo di lavorazione, che deriva dai risultati dell’attività di ricerca, dai risultati ottenuti nelle prove di panificazione e dai suggerimenti dei panificatori. Contemporaneamente sono stati portati avanti gli studi per la preparazione del marchio commerciale e del suo regolamento d’uso

Lightweight client-pull protocol for mobile communication
Get PDFConsumer mobile devices, such as cellular phones and PDAs, rely on TCP/IP as main communication protocol. However, cellular networks are not reliable as wired and wireless LAN, due to both users mobility and geographical obstacles. Moreover, limited bandwidth outside urban areas requires an application level data priority management, in order to improve user experience and avoid communication stack deadlocks. This paper presents early specification and first prototype of the LCPP (Lightweight Client-Pull Protocol), a UDP-based communication protocol specially designed to provide better performance, fast responsiveness and save processing power on mobile devices. Using some concepts adopted in the field of P2P file sharing, LCPP provides data priority management approach, which enables application to negotiate concurrent access to communication channel and to be notified about delaying, network congestion or remote device inability to process data
Collaborative immersive visualization without goggles -- experiences in developing a holographics display system for medical applications
No full textConference held in Turin, Italy, November 3-5, 2005. CD ROM ProceedingsIn this contribution, we report on the development of a novel holographic display technology that targets multiple freely moving naked eye viewers and of a collaborative medical application prototype that aims at exploiting this technology to provide medical specialists with a truly interactive 3D collaborative environment for diagnostic discussions and/or pre-operative planning
