Instrumenting programs with code to monitor runtime behavior is a common technique for profiling and debugging. In practice, instrumentation is either inserted manually by programmers, or automaticall...
Given a set P of n uncertain points on the real line, each rep-resented by its one-dimensional probability density function, we consider the problem of building data structures on P to answer range qu...

2015/8/31
Hand drawn sketches can be used as an aid in spatial queries for identifying spatial relationships. This paper is developing a framework
describing the computational methods for solving these queries...
We construct public-key systems that support comparison queries (x > a) on encrypted data as well as more general queries such as subset queries (x in S). These systems also support arbitrary conjunct...
