SUMMARY Since the Boyer-Moore algorithm was described in 1977, it has been the standard benchmark for the practical string search literature. Yet this yardstick compares badly with current practice. We describe two algorithms that perform 47% fewer comparisons and are about 4.5 times faster across a wide range of architectures and compilers. These new(More)
Measuring O 2 flux across the sediment-water interface is a widely used approach to assess benthic production and mineralization of organic material in aquatic environments. In addition, many other biogeochemical sediment processes are tightly regulated by O 2 exchanged across the sediment-water interface. Hence, the ability to monitor this flux accurately(More)
As the systems we build become more complex, understanding and managing their behavior becomes more challenging. If the system's inputs are within an acceptable range, it will behave predictably. However, the system may " fall off the cliff " if input values are outside this range. This nonlinear behavior is undesirable, because the system no longer behaves(More)
An intertidal Crassostrea virginica oyster reef was instrumented to quantify processes affecting boundary layer flow, suspended sediment deposition and erosion, and the flux of oxygen to and from the benthos. Velocity and suspended sediment concentrations were measured at opposing sides of the reef and sediment fluxes, due to the combined effects of(More)
