Michael Screech (1926-2018)

Approximate OWL-Reasoning with Screech

With the increasing interest in expressive ontologies for the Semantic Web, it is critical to develop scalable and efficient ontology reasoning techniques that can properly cope with very high data volumes. For certain application domains, approximate reasoning solutions, which trade soundness or completeness for inctreased reasoning speed, will help to deal with the high computational complexi...

Jet Flow Field during Screech

Measurements were made of the flow field structure and the near field parameters of a jet exhausting from a sonic nozzle with a 1.27 cm exit diameter. Compressed air was used for obtaining stagnation pressures up to ~ 5 atmospheres. The jet exhausted vertically from a settling chamber into an acoustically insulated room and through an insulated duct out through the roof. Measurements were made ...

Irwin Rose (1926-2015).

On June 2, 2015, Irwin (Ernie) Rose died quietly in his sleep at age 88, after a long and fruitful lifetime of sleuthing for the secrets of life at the molecular level. Truly great scientists are much more than the sum of their publications and awards. This is especially true for Ernie who, when informed that he had been awarded the 2004 Nobel Prize in Chemistry, wondered aloud whether he reall...

David Hubel 1926–2013

Hydraulic microelectrode advancermade by David Hubel. David Hubel was a giant in our field, yet he waswarm, friendly, and humble in person. He and Torsten Wiesel, following in the footsteps of their mentor Steve Kuffler, discovered fundamental principles of information processing in the brain and fundamental principles of how the brain wires itself up. I think many people in the field see David...
