Presented is an investigation into the modeling, active control design, and simulation of a generic horizontal pendulum wave energy converter, known as a PWEC. A description is provided of the dominant attributes PWECs have, showcasing their promising potential as wave energy converters. Seeking to further promote this potential, an active...
Vertical Axis Pendulum Wave Energy Converters (VAPWECs) are thought to be both effective and robust at converting ocean wave energy into usable electricity. Seeking to build upon and investigate such potential, this work examines the merits of actively controlling a generic VAPWEC's pendulum for the purpose of increasing the converter's...
Juvenile survival and recruitment can be more sensitive to environmental, ecological and anthropogenic factors than adult survival, influencing population-level processes like recruitment and growth rate in long-lived, iteroparous species such as southern right whales. Conventionally, Southern right whales are individually identified using callosity patterns, which do not stabilise until 6–12...
Superpopulation capture–recapture models are useful for estimating the abundance of long-lived, migratory species because they are able to account for the fluid nature of annual residency at migratory destinations. Here we extend the superpopulation POPAN model to explicitly account for heterogeneity in capture probability linked to reproductive cycles (POPAN-τ). This...
Since the decimation of the southern right
whale Eubalaena australis population in New Zealand by
whaling, research on its recovery has focused on the wintering
ground at the Auckland Islands, neglecting potentially
important wintering habitat at Campbell Island. For
the first time in 20 years we conducted an expedition to...
The objectives of this study were (a) to measure the amount
of cross-pollination caused by three bee species at 10, 20 and 40
rods distance from a foreign pollen source, (b) to measure the effects
of bee species, planting pattern and season on broad sense heritability
estimates for seed yield...
Crops were grown at the experimental farms using accepted cultural practices ( within the limits of experimentation) or trials were conducted on growers' fields. Most experiments were designed as randomized complete blocks with three to five replications. Herbicide treatments were applied uniformly with precision plot sprays. Unless otherwise indicated, preplant...
In the fall 2015, students at the University of Missouri embarked upon an extended series of protests aimed at calling out the University’s failure to address recent racist incidents against Black students and a larger oppressive campus culture. The protests prompted the creation of a student group led largely by...
Several wave energy converter designs have been recently proposed that are made of flexible materials. Flexible devices are able to generate electricity by being stretched, and are intended to simplify deployment and maintenance concerns over existing wave energy devices. Due to the relative infancy of flexible wave energy converters, however,...
The overall purpose of this study was to investigate
certain aspects of the effectiveness of adult career programs.
The central focus was to compare the differences
in vocational self-concept crystallization among the participants
exposed to the classroom group program and the
individualized telecourse programs. Further information
was desired regarding the...
