This paper defines the Non-Blocking Atomic Commitment problem in a message-passing asynchronous system and determines a failure detector to solve the problem. This failure detector, which we call the modal failure detector star, and which we denote by M*, is strictly weaker than the perfect failure detector P but strictly stronger than the eventually perfect failure detector ◇P. The paper shows...

This paper develops an entire communication support system for speech handicaps using lip reading. Our system is a high level system and consists of a face detector using Viola-jones method, lip detector based on active appearance model, utterance section detector, determined phrase recognizer using DP matching, camera controller, and message output. We implemented our system in the commercial ...
