Electronic collaboration is a pervasive concept that influences practically all human domains, from work to learning to entertainment; making possible the collaboration between two or more distant persons. To encourage the exploitation of this new phenomenon, we have to demonstrate its benefits using validated evaluating methods that ensure the reliability of its effects. However, e-collaboration...
This paper advises the use of k-dimensional size functions for comparison and retrieval in the context of multidimensional shapes, where by shape we mean something in two or higher dimensions having a visual appearance. The attractive feature of k-dimensional size functions is that they allow to readily establish a similarity measure between shapes of arbitrary dimension, taking into account different...
The silicon-vertex-trigger (SVT) [1,2] at CDF is made of two pipelined processors: the associative-memory, AM [3,4], finding low precision tracks (roads) and the track-fitter, TF, refining the track quality with high-precision fits. We propose to extend the SVT use, now mostly focused on B-physics, to high-PT physics as a tracker in the forward/backward region. The upgraded SVT structure is easily...
The silicon vertex trigger (SVT) in the CDF experiment at Fermilab performs fast and precise track finding and fitting at the second trigger level and has been a crucial element in data acquisition for Run II physics. However as luminosity rises, multiple interactions increase the complexity of events and thus the SVT processing time, reducing the amount of data CDF can record. The SVT upgrade aims...
