Most fishes exhibit differences in activity patterns from day to night, with a switch from
high to low activity at dusk and reverse at dawn. Marine reef fishes show similar behavior
among sites, despite dissimilar species assemblages, suggesting that common selection pressures
are leading to convergent behavior. Few studies to...
Urban stormwater runoff contains pollutants that have a detrimental effect on pond water quality and watershed water quality. Stormwater best management practices (BMPs), such as a constructed wetland, can treat these pollutants through processes like infiltration, adsorption, and plant uptake. It is hypothesized that the surface-runoff fed pond at Bruce...
The ability of Cumella vulgaris to avoid burial under different
rates of sedimentation and to recover from burial once buried was
studied. Sedimentation rates higher than 0. 25 cm/mm are
necessary to bury 50% of C. vulgaris with the deposition of 4 cm of
sediment.
Cumella vulgaris can swim several...
This collection consists of autobiographical essays which center around my father,
my first husband, and my backyard. All of the pieces are recollections, and most occur
either from my study inside the house, or from the deck outside, looking at the yard. The
Preface is the story of how I...
We describe a CASE tool for designing hard real-time applications, called HaRTS. The design tool supports a hierarchical design diagram which combines the control and data flow of a hard real-time application. The design hierarchy separates a design into self-contained subdesigns. Yet, the design can be flatten to give you...
A test system was developed and used to
investigate ice/structure interaction with centrifugal
modeling. The test system was designed to perform two
main functions: (1) create a uniform ice sheet, and
(2) drive a model structure through the ice sheet at a
constant speed. Both of these functions were required...
Ocean wave energy converter technology continues to advance and new developers continue to emerge, leading to the need for a general design, modeling, and testing methodology. This work presents a development of the process of taking a wave energy converter from a concept to the prototype stage. A two body...
Application supporting a Graphical User Interface (GUI) are difficult to create. Their inherent complexity, their interdependence with many other disciplines, and the inadequacy of the existing tools leave the programmer with too much to do. In particular, almost no help is provided to create application-specific code. Some visual formalisms such...
A portion of this study was initiated to provide the
basis for implementing a chill unit accumulation procedure
in Yemen. Most continuous or daily minimum, maximum
temperature models severely underestimated chilling units,
and slight modifications offered little improvement for the
complex models. Only the Crossa Raynaud formula approximated
generally accepted...
