A new graphics client prototype for the HepRep protocol is presented. Based on modern toolkits and high level languages (C++ and Ruby), Fred is an experiment to test applicability of scripting facilities to the high energy physics event display domain. Its flexible structure, extensibility and the use of the HepRep protocol are key features for its use in the astroparticle experiment GLAST.
Recently it has been proposed, using the formalism of positive-operator-valued measures, a possible definition of quantum coordinates for events in the context of quantum mechanics. In this short note we analyze this definition from the point of view of local algebras in the framework of local quantum theories.
We examine the longstanding problem of introducing a time observable in Quantum Mechanics; using the formalism of positive-operator-valued measures we show how to define such an observable in a natural way and we discuss some consequences.
