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...

Some may think that any phenomenon that has not been explained needs explanation. Other...
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 کاملExplanation of normative declines in parents' knowledge about their adolescent children.
This study aimed to explain why parental knowledge of adolescents' whereabouts declines with age. Such an investigation is important because previous studies have established an association between behavior problems and low levels of parental knowledge. A time-sequential sample comprising 2415 adolescents aged 13-18 years was investigated on five annual occasions. Each year, parental knowledge ...
