We investigate the protection of migrating agents against the untrusted sites they traverse. The resulting calculus provides a formal framework to reason about protection policies ...
Error propagation is a central problem in grid computing. We re-learned this while adding a Java feature to the Condor computational grid. Our initial experience with the system w...
We describe a model-based height controller for a hopping robot with a pneumatically powered leg. The controller explicitly models variation in the leg angle and height. Using an ...
— While planning the execution of report-generation workloads, database administrators often need to know how long different query workloads will take to run. Database systems ru...
Recently, object-oriented languages, such as C , have been extended with language features prevalent in most functional languages: parametric polymorphism and higher-order function...
