Acoustic position estimation is used where high accuracy navigation is required over a small area, such as for searching or for collecting gravitational or geomagnetic data. In this position estimation method, a surface ship or submersible periodically sends out a high-frequency acoustic 'ping' at a prearranged frequency. This ping is...
Our confidence in software systems depends on our confidence in the exhaustiveness of our testing. As software systems get more complex, the task of exhaustive testing becomes more complex and even infeasible in some cases. In order to build less error prone systems, we therefore need to not only focus...
Farmers rely almost exclusively on the imported European honeybee (Apis mellifera L.)
for fruit and vegetable crop pollination services. The recent decline in honeybee health
has underscored the danger of relying on a single species to provide vital services.
Increasing pollinator biodiversity with native bees may provide biological insurance

In the early part of his philosophical career, Paul Ricoeur worked out a general theory of symbols which he illustrated with the symbols of evil. He subsequently explained this theory in several essays (his final major statement on symbols can be found in Interpretation Theory: Discourse and the Surplus of...
