The Oceanographic Systems Laboratory at Woods Hole Oceanographic Institution has developed a small, low power, single-axis, range-gated pulse-coherent Doppler sonar, that is primarily intended for boundary layer turbulence studies. This instrument is composed of a receiver-transmitter, a 24MHz analog-to-digital converter, a down converter, and a low power(More)
The Oceanographic Systems Laboratory at Woods Hole Oceanographic Institution has developed a low-power multi-frequency sonar board capable of operating at a wide range of frequencies from 200 KHz to 2 MHz and suitable for a wide range of applications. Its features include a transmitter, a receiver with gain control, a 24 MHz analog-to-digital converter, a(More)
A series of studies was performed to develop an alternative to the U.S. Environmental Protection Agency's gold standard IM240 mass-based emission test. The new IM147 test was based on the second phase of the IM240 that consists of 147 sec of transient vehicle operation. Paired IM240/IM147 tests were conducted on vehicles ranging from 1981 to 1996 to(More)
As AUVs continue to gain popularity around the world, the need for robust launch and recovery methods is growing as well. Larger vehicles with more capabilities are much more difficult to safely recover post-mission than smaller man-portable systems. Line Capture Line Recovery (LCLR) combines several key technologies developed by the Woods Hole(More)
The effectiveness of using a computer supported collaborative learning tool in a college-level Java Programming class is investigated in this paper. As an initial attempt, eight collaborative learning laboratory sessions were created. This paper will discuss students' responses to these sessions and report the difficulties encountered in this experiment,(More)
CARB staff has performed an economic analysis for its proposed Low Carbon Fuel Standard (LCFS) concluding that adoption of the standard will result in a cost savings to California motorists of up to $3.4 billion per year by 2020 ($11 billion over the period from 2010 to 2020). The staff’s emissions analysis also concludes that there will be a significant(More)
Elliptic curve discrete logarithm problem (ECDLP) is the base of the security of elliptic curve cryptography (ECC). The verification of the security of ECC has been studied by solving an ECDLP. However, we need a large amount of computational resources for the verification. Then, this paper proposes a method gathering computational resources with Web-based(More)
