A high-resolution primitive equation model simulation is used to form an energy budget for the principal semidiurnal tide (M₂) over a region of the Hawaiian Ridge from Niihau to Maui. This region includes the Kaena Ridge, one of the three main internal tide generation sites along the Hawaiian Ridge and...
Reducing garment waste and finding sustainable alternatives within the apparel industry has gained momentum in recent years as concerns increase towards the polluting nature of the industry. Designing for longevity, by focusing on aspects such as emotional and physical durability have been cited as possible solutions. The purpose of this...
Forests should be monitored and measured frequently to ensure its sustainability and continuity of carbon sequestration. However, conventional monitoring methods are costly and labor intensive. New technologies, such as unmanned aircraft systems (UAS) can be used as an alternative method to monitor and measure forests. The objective of this study...
This research presents an analysis of thermal stratification in the reactor cold leg of the Advanced Plant Experiment-Combustion Engineering (APEX-CE). This phenomenon may be a precursor leading to a Pressurized Thermal Shock (PTS) event in a nuclear power plant. This work was performed in support of the U.S. Nuclear Regulatory...
A new incremental ADC is proposed which extends the order of a
conventional incremental ADC from N to (2N-1) by way of a two-step
operation. For a given conversion time, the duration of each step can be
optimized. For an Nth-order IADC, the performance is equivalent to that
of a...
Complex conceptual system design trade studies
traditionally consider risk after a conceptual design has
been created. Further, one person is often tasked with
collecting risk information and managing it from each
subsystem. This paper proposes a method to explicitly
consider and trade risk on the same level as other important...
The objective of this study was to evaluate the presence
of methicillin-resistant Staphylococcus aureus and
coagulase-negative Staphylococcus spp. in bulk tank
milk samples from 288 organic and conventional dairy
farms located in New York, Wisconsin, and Oregon
from March 2009 to May 2011. Due to recent publications
reporting the presence...
Euphausia pacifica occupy a remarkably wide range of ecosystems. We examined the
differences in brood sizes from eight regions of the North Pacific to explore how variation
in the brood size might contribute to their success over such a range. We show
a compilation and analysis of short-term E. pacifica...
Premise of research. The lianoid habit is found in 125 extant plant families and is most diverse and abundant in structurally complex forests, such as tropical forests. A stem with lianoid anatomy is described from Cretaceous sediments of Hornby Island, British Columbia.
Methodology. The stem segment, 2.5 cm in diameter...
Extended-counting A/D converters are proposed which achieve a high
accuracy by performing the conversion in several cycles. During the
first cycle, the circuit performs as an incremental ADC, while during the
remaining ones it acts as a multi-slope counting converter. With only
one opamp and a single-slope ADC, the accuracy...
