Visitors Unchained
Traversing and transforming abstract syntax trees that involve name binding is notoriously di cult to do in a correct, concise, modular, customizable manner. We address this problem in the setting of OCaml, a functional programming language equipped with powerful object-oriented features. We use visitor classes as partial, composable descriptions of the operations that we wish to perform on abs...

متن کاملUnchained polygons and the N-body problem
We study both theoretically and numerically the Lyapunov families which bifurcate in the vertical direction from a horizontal relative equilibrium in R. As explained in [CF1], very symmetric relative equilibria thus give rise to some recently studied classes of periodic solutions. We discuss the possibility of continuing these families globally as action minimizers in a rotating frame where the...
متن کاملSpatial imaging in color and HDR: prometheus unchained
The Human Vision and Electronic Imaging Conferences (HVEI) at the IS&T/SPIE Electronic Imaging meetings have brought together research in the fundamentals of both vision and digital technology. This conference has incorporated many color disciplines that have contributed to the theory and practice of today's imaging: color constancy, models of vision, digital output, high-dynamic-range imaging,...
متن کاملVisualizing Museum Visitors' Behavior
Museum curators are interested in understanding what is happening in their museum: what exhibitions and exhibits do visitors attend to, what exhibits visitors spend most time at, what hours of the day are most busy at certain areas in the museum and more. We use automatic tracking of visitors’ position and movements at the museum to log visitor information. Using this information, we provide an...
