The calculation of interplanetary trajectories is a numeric problem which requires a high degree
of precision for the results to be accurate. A computer program was written for this project which
uses leapfrog integration combined with Newton’s method of iterative root finding to find ideal
interplanetary trajectories. Reasonable initial conditions...
Quantum mechanics provides a conventional theory of scattering that is limited in
at least two ways: it focuses exclusively on the asymptotic regime and, in a more general
sense characteristic of all quantum descriptions, provides no concrete account of individual
particle evolution in spacetime. This is particularly true during the...
A method to design foot trajectory in Cartesian
coordinates for a six-leg walking machine is presented in
this thesis. The walking machine is based on the geometry of
the darkling beetle.
The walking procedure developed by Y.S. Baek is
introduced first to provide step length and leg swing time
for...
I explore the proposition that evolutionary biology is
currently in the midst of its greatest period of synthesis. This period,
which I call the Ongoing Synthesis, began in 1963 and continues at
the present time. I use analysis of citations, conduct, and content to
compare the Ongoing Synthesis to widely...
DNA mismatch repair (MMR) is an evolutionarily conserved process used by cells to decrease mutation rates, thereby increasing genetic stability and reducing cancer risk. Germline mutations in the MMR gene MLH1 have been identified in Lynch Syndrome patients, and in many cases are suspected but not confirmed as causative for...
Current research into path planning for Unmanned Aerial Vehicles (UAVs) has placed a major focus on accomplishing the goals of various agents while avoiding collisions between each other. However, there has been little focus on whether the planned trajectories are fair for each agent.
This work provides an answer to...
In this thesis, a method is presented to construct minimum-time
robot trajectories for predefined Cartesian end-effector path in a
workspace containing obstacles. The method is preferably applied to a
geometric collision-free path of a SCARA robot by using the theories of
Bezier, B-spline, and parabolic blending curves. The motion of...
The change process for clients in long-term adolescent residential treatment has received heightened research attention for the past 15-year (Gass, 2006). The research indicates that individuals enrolled in long-term adolescent residential treatment centers, on average, experience improved psycho-social functioning to degrees that are statistically and clinically significant (Behrens & Satterfield,...
The effect of heterozygosity on the phenotypic stabilities of six
morphological plant characteristics was studied in hybrid crosses of
two self-pollinated barley species Hordeum vulgare L., emend Lam.
and Hordeum distichum L., emend Lam. Experimental material
consisting of parents and their F₁ diallel progeny were grown at two
field locations...
The near-surface circulation in the Santa Barbara Channel and off the coast of central and southern California is described based on 20 releases of drifters
drogued 1 m beneath the surface from 12 sites within the channel at bimonthly
intervals. This description includes small-scale features of the circulation which are...
