The selection of a project among a set of possible alternatives is a difficult task decision makers have to face. Difficulties in selecting a project arise because of the different goals involved and because of the large number of attributes to consider. Our approach is based upon a fuzzy extension of the Analytic Hierarchy Process (AHP). This paper focuses(More)
Ortholumen is a light pen based tabletop interaction system that can employ all the pen’s spatial degrees of freedom (DOF). The pen’s light is projected from above onto a horizontal translucent screen and tracked by a webcam sitting underneath, facing upwards; system output is projected back onto the same screen. The elliptic light spot cast by the pen(More)
The aim of this study is to identify the minimum safe amount of effective remnant liver volume (ERLV) in patients undergoing a major hepatectomy. Thirty-eight consecutive major hepatectomies (resection of > or = 3 Couinaud segments) performed between July 1999 and March 2004 in which a frozen section liver biopsy was obtained were included. No patient had(More)
BACKGROUND Induction with monoclonal antibodies for prevention of acute cellular rejection (ACR) may avoid many of the adverse events associated with polyclonal antibodies. Basiliximab, a chimeric monoclonal antibody directed against the alpha-chain of the interleukin 2 receptor (CD25), has been extensively evaluated as an induction therapy for kidney(More)
International regulatory authorities view risk management as an essential production need for the development of innovative, somatic cell-based therapies in regenerative medicine. The available risk management guidelines, however, provide little guidance on specific risk analysis approaches and procedures applicable in clinical cell therapy manufacturing.(More)
A common problem in optical motion capture is the so-called missing marker problem. The occlusion of markers can lead to significant loss of tracking accuracy unless continuous data flow is guaranteed by computationally demanding interpolation or extrapolation schemes. Since interpolation algorithms require data sampled before and after an occlusion, they(More)
It is becoming increasingly more common for people to own botha smartphone and a tablet, providing a design opportunity to leverage the combination of these two formfactors. Our work aims to explore this by: a) defining the design space of distributed input and output solutions that rely on and benefit from phone--tablet collaboration, both physically and(More)
A common problem in optical motion capture of human-body movement is the so-called missing marker problem. The occlusion of markers can lead to significant problems in tracking accuracy unless a continuous flow of data is guaranteed by interpolation or extrapolation algorithms. Since interpolation algorithms require data sampled before and after an(More)
For Emergency Response Management (ERM) personnel the processes of reaching common ground, a common operational picture (COP), and a common understanding of an emergency situation are of key importance. We present a concept and a system, called CERMIT to support co-located and remote actors in organizational ERM training and work practice. CERMIT is based(More)
In this paper we focus on transmission and failure of transmission of warrant. We identify three individually necessary and jointly sufficient conditions for transmission of warrant, and we show that their satisfaction grounds a number of interesting epistemic phenomena that have not been sufficiently appreciated in the literature. We then scrutinise(More)
