Establishing Metrics To Encourage Broader Use Of Atomic Requirements – A Call For Exchange And Experimentation, William L. Honig
Establishing Metrics To Encourage Broader Use Of Atomic Requirements – A Call For Exchange And Experimentation, William L. Honig
Computer Science: Faculty Publications and Other Works
There are seemingly many advantages to being able to identify, document, test, and trace single or “atomic” requirements during system development and maintenance. Ongoing work with Agile development has focused on “user stories” that can capture individual features for implementation. However, it is still difficult to evaluate the quality of such requirements and teaching their creation is difficult.
Based on a working definition of atomic requirement, this paper proposes a set of metrics for their evaluation. Ten metrics designed to measure atomic requirements are presented here: five used on individual requirements statements and five applied to a requirements document or …

Drone-Based Airborne Vlf-Em In Detecting Groundwater Contamination Due To Landfill Leachate, Chanho Park, Mine Dogan
Waldo Library Student Exhibits
Modern landfills follow a strict state and federal regulation on their location, design, operation and monitoring practices. One of the key focus in the regulations is in terms of leachate. While the exact composition of the leachates depends on various factors such as waste composition and degradation processes, in general they contain groups of dissolved organic matter, inorganic cations and heavy metals.
Very Low Frequency-Electromagnetic (VLF-EM) has been widely used for delineating leachate plume direction and boundaries. Previous studies using VLF-EM were carried out as on-ground measurements due to limitations in technologies. With the advancements in Unmanned Airborne Systems (UAS), …

To achieve the Paris Agreement’s goal of limiting the increase in global average temperatures to “well below 2 degrees Celsius,” and ideally 1.5 degrees Celsius, above pre-industrial levels, global greenhouse gas (“GHG”) emissions must reach net zero in the second half of the century. The global community is not currently on track to achieve net zero emissions. In fact, with the exception of a slight dip during the Covid-19 pandemic, emissions have risen steadily in recent years. This, together with the increasingly visible impacts of climate change, has prompted growing interest in the possibility of removing GHGs directly from the …

Pressure Dependence Of The Rate Coefficient Of Ozone Using Master Equation Simulations Of Recombination Kinetics, Adil Yermek
Master's Theses (2009 -)
The ozone layer in Earth’s atmosphere is distinctive and crucial for the evolution of life. Investigating the process of ozone formation aids in comprehending the evolution of our planet’s atmosphere. The reaction that forms ozone is O + O2 → O3. One can describe ozone forming reaction approximately using Lindeman mechanism, which is very handy. However, its limitation arises from assuming a steady-state approximation, which neglects transient dynamics and complexities that could impact reaction kinetics under non-equilibrium conditions. For this reason, Master Equation simulations can be seen as an enhancement or extension of the Lindemann mechanism, providing a thorough understanding …

Coral reefs and their associated landforms (carbonate islands and shorelines) are under increasing threat from the effects of anthropogenic climate change, including sea level rise (SLR). The ability of a reef to keep up with SLR depends on the rate of calcium carbonate accretion. Census-based carbonate budgets quantify rates of net calcium carbonate production on a reef and facilitate estimations of vertical reef accretion potential (RAP). To date, most carbonate budget studies have been undertaken in clear-water settings resulting in a limited understanding of how inshore reefs situated in more marginal environmental settings are functioning now and under future climate …

Effective conservation of endangered species depends on knowledge of their distributions, but species detection can often be challenging. An example of this is provided by the Critically Endangered Margaret River burrowing crayfish (Engaewa pseudoreducta), which is highly cryptic. Due to the burrowing habit of this crayfish, detection of this species currently requires a great deal of effort, the results are often non-conclusive, and, as it involves manual excavation of their burrows, the habitat of this and other species is destroyed in the detection process. In response to these challenges, this study developed and optimized a species-specific probe-based qPCR assay targeting …

Systematic Comparison Of Ultraviolet Vs. White Light For Lightboard Illumination, Craig Looney
Systematic Comparison Of Ultraviolet Vs. White Light For Lightboard Illumination, Craig Looney
Physics Faculty Publications
Since Peshkin’s invention of the original open-hardware lightboard, tempered low-iron glass has been the preferred lightboard writing surface: low-iron for maximal transparency, tempered for safety and durability. Unfortunately, the tempering process often leaves marks on the glass that become highly visible when illuminated with edge-mounted white LEDs. One obvious idea is to illuminate the glass with UV LEDs; the UV light should cause the fluorescent marker writing to visibly fluoresce, while UV light scattered by defects should be invisible. McCorkle and Whitener (2017, 2020) reported a qualitative performance enhancement for near-visible UV blacklight illumination, but no systematic investigations have been …

Radio Propagation Through Density Irregularities In The Auroral Ionosphere, Pralay Raj Vaggu
Doctoral Dissertations and Master's Theses
A radio wave propagating through a structured or turbulent ionosphere undergoes multiple effects, such as refraction, diffraction, etc., that distort the incident radio wave by inducing phase and amplitude fluctuations. These fluctuations are called ionospheric scintillation. Scintillation effects can be detrimental to Global Navigation Satellite Systems (GNSS) such as Global Positioning System (GPS), but the observed effects can be used as a tool to study the underlying plasma process that causes scintillation. Scintillation is commonly seen in equatorial and high-latitude regions. This study centers around the scintillation and its causative plasma processes that dominantly happen in the high-latitude ionosphere …
