Hypothetical queries are queries embedding hypotheses about the database. The embedded hypothesis in a hypothetical query indicates, so to say, a state of the database intended for...
In this paper, we aim to estimate the similarity between users according to their GPS trajectories. Our approach first models a user’s GPS trajectories with a semantic location ...
We introduce a Hoare logic for higher-order functional languages with control operators such as callcc. The key idea is to build the assertion language and proof rules around an e...
Cminor is a mid-level imperative programming language; there are proved-correct optimizing compilers from C to Cminor and from Cminor to machine language. We have redesigned Cminor...
E-FRP is declarative language for programming resourcebounded, event-driven systems. The original high-level semantics of E-FRP requires that each event handler execute atomically...
