A radioactive particulate release experiment to produce a near-field ground deposition representative of small-scale venting from an underground nuclear test was conducted to gather data in support of treaty capability development activities. For this experiment, aCO₂‐driven “air cannon” was used to inject ¹⁴⁰La, a radioisotope of lanthanum with 1.7‐d half-life...
Ocean acidification (OA), the change in ocean chemistry due to increasing concentrations of anthropogenic carbon dioxide in the atmosphere, is an environmental problem that is an active area of scientific research yet remains largely outside of the public’s awareness. It is often assumed that if we raise OA awareness, then...
Recent state and national standards have increased the interest in engineering at the K-12 level. Science standards, in particular, have begun to make the case for including engineering throughout the K-12 scope of study. Despite the increased attention to engineering, the characteristics and uniqueness of the field of engineering are...
The atomic solid state energy (SSE) scale is introduced as a tool for inorganic materials design. The SSE scale is obtained by assessing an average electron affinity (EA) (for a cation) or an average ionization potential (IP) (for an anion) for each atom using data from compounds having that specific...
A representation for the process of mechanical design,
along with its computer implementation is presented and
discussed. The representation consists of three
fundamental concepts: design objects, constraints, and
decisions. The design objects are the structures with
which the physical artifacts of the design are described.
A design object consists of...
In order to observe laser phase noise, this noise must be converted to
amplitude noise, which can be achieved using either an interferometer or an
absorption resonance in an atomic/molecular vapor or gas. When phase noise is
converted to amplitude noise, it is manifested as a heterodyne signal in the...
Humboldt County has several areas which have naturally
high to extreme wildland fire hazards. Recent settlement within
these areas increases the likelihood of a destructive fire. This
report examines the extent and degree to which climate, slope and
vegetation influence the wildland fire hazard in Humboldt County,
as well as...
We consider the problem of strategic adversarial planning in a Real-Time Strategy (RTS) game. Strategic adversarial planning is the generation of a network of high-level tasks to satisfy goals while anticipating an adversary's actions. In this thesis we describe an abstract state and action space used for planning in an...
Antimicrobial peptides (AMPs) play an important role in the innate immune system. Determining the pathways by which these proteins are regulated allows for modulation of their expression for better health. Two families of antimicrobial peptides have been studied in humans: cathelicidins and defensins. There is a single cathelicidin in humans...
