Creem-Regehr, Sarah Hope; Willemsen, Peter; Gooch, Amy A.; Thompson, William B. | The influence of restricted viewing conditions on egocentric distance perception: implications for real and virtual environments | Three experiments examined the influence of field of view and binocular viewing restrictions on absolute distance perception in the real world.

Riloff, Ellen M. | Information extraction as a stepping stone toward story understanding | Historically story understanding systems have depended on a great deal of handcrafted knowledge. Natural language understanding systems that use conceptual knowledge structures (Schank and Abelson 1977; Cullingford 1978; Wilensky 1978; Carbonell 1979; Lehnert 1981; Kolodner 1983) typically rely on ... | Information extraction; Story understanding | 1999 |

Henderson, Thomas C.; Cohen, Elaine | Innate theories as a basis for autonomous mental development | Sloman (in robotics), Chomsky and Pinker (in natural language), and others, e.g., Rosenberg (in human cooperative behavior) have proposed that some abstract theories relevant to cognitive activity are encoded genetically in humans. The biological advantages of this are (1) to reduce the learning ... | Autonomous mental development | 2009 |

Henderson, Thomas C. | Instrumented sensor system - practice | In previous work, we introduced the notion of Instrumented Logical Sensor Systems (ILSS) that are derived from a modeling and design methodology [4, 2].

Henderson, Thomas C. | Instrumented sensor system architecture | Sensor systems are becoming ubiquitous throughout society, yet their design, construction and operation is still more of an art than a science.

Freire, Juliana | Integrated scientific workflow management for the Emulab network testbed | The main forces that shaped current network testbeds were the needs for realism and scale. Now that several testbeds support large and complex experiments, management of experimentation processes and results has become more difficult and a barrier to high-quality systems research.
