Symbolic execution is a powerful automated technique for generating test cases. Its goal is to achieve high coverage of software. One major obstacle in adopting the technique in pr...
Abstract. We present a general scheme for automated instantiation-based invariant discovery. Given a transition system, the scheme produces k-inductive invariants from templates re...
The automatic and unobtrusive identification of user's activities is one of the challenging goals of context-aware computing. This paper discusses and experimentally evaluate...
Abstract-- Mobile devices are becoming increasingly powerful with regards to processing speed, networking capabilities, storage capacity etc. While these improvements open up new p...
A new context management framework, which supports the interaction between different domain context managers, is proposed. Two different context producerconsumer patterns are defin...
In this paper, we propose an algorithm to estimate 2D shapes and positions of obstacles such as buildings using GPS and wireless communication history of mobile nodes. Our algorith...
