We analyze a tradeoff between early warnings of plan failures and false positives. In general, a decision rule that provides earlier warnings will also produce more false positives. Slack time envelopes are decision rules that warn of plan failures in our Phoenix system. Until now, they have been constructed according to ad hoc criteria. In this paper we show that good performance under differe...

Human-computer interaction (HCI) and artificial intelligence (AI) share a long history of research. Concepts such as problem spaces, goals and operators, rationality, and computational models of cognition have significantly influenced research directions in both fields. Recently the concept of agents has sparked a common interest among AI and HCI researchers. Our demonstration focuses on interf...

HORTON, THOMAS E. HabilisDraw: A Tool-based Direct Manipulation Software Environment. (Under the direction of Associate Professor Robert St. Amant). Direct manipulation interfaces already employ a weak analogy to the use of physical tools in the real world. Despite certain tradeoffs, a stronger application of tool-using principles can lead to improvements in the design of software interfaces. I...

L’affaire Dubuisson concerne le procès criminel de Pauline qui a abattu son ancien amant. La mémoire l’Occupation joué un rôle déterminant dans ce en 1953.

Plants grow under climatic changing conditions that cause modifications in vegetative and reproductive development. The degree of changes in organ development i.e. its phenotypic plasticity seems to be determined by the organ identity and the type of environmental cue. We used intraspecific competition and found that Antirrhinum majus behaves as a decoupled species for lateral organ size and nu...
