Boxer is a semantic parser for English texts with many input and output possibilities, and various ways to perform meaning analysis based on Discourse Representation Theory. This involves the various ways that meaning representations can be computed, as well as their possible semantic ingredients.

This paper presents a novel adaptive control methodology for a class of uncertain systems in the presence of time-varying unknown nonlinearities. The adaptive controller ensures uniformly bounded transient and asymptotic tracking for system’s both input and output signals simultaneously. The performance bounds can be systematically improved by increasing the adaptation rate. Part II extends the...

Multiple Pointing Input System(MPIS) allows concurrent manipulation of multiple pointing devices, and is targeted as a generic input system. This paper reports on an experimental evaluation on our MPIS prototype system. The system allows concurrent manipulation of multiple pointing devices. The experiment has subjects sort 8 objects on the screen in displayed order. We found that concurrent man...
