Quantification Of Radicals Generated In A Sonicator, K. O. Badmus, J. O. Tijani, C. P. Eze, O. O. Fatoba, L. F. Petrik

Mining Engineering Faculty Research & Creative Works

The hydroxyl radical (OH•) is a powerful oxidant produced as a consequence of cavitation in water. It can react nonspecifically in breaking down persistent organic pollutants in water into their mineral form. It can also recombine to form hydrogen peroxide which is very useful in water treatment. In this study, terephthalic acid (TA) and potassium iodide dosimetry were used to quantify and investigate the behavior of the generated OH radical in a laboratory scale sonicator. The 2-hydroxyl terephthalic acid (HTA) formed during terephthalic acid dosimetry was determined by optical fiber spectrometer. The production rate of HTA served as a means …

The Age Of Scalia, Jamal Greene

Faculty Scholarship

During periods of apparent social dissolution the traditionalists, the true believers, the defenders of the status quo, turn to the past with an interest quite as obsessive as that of the radicals, the reformers, and the revolutionaries. What the true believers look for, and find, is proof that, once upon a time, things were as we should like them to be: the laws of economics worked; the streams of legal doctrine ran sweet and pure; order, tranquility, and harmony governed our society. Their message is: turn back and all will be well.

Corporate Criminal Liability For Algorithmic Price Fixing In Canada, Theodore Milosevic

Canadian Journal of Law and Technology

The use of computerized algorithms is increasingly common in the modern business environment. An algorithm can be defined as ‘‘a set of mathematical instructions or rules that, especially if given to a computer, will help to calculate an answer to a problem.” As noted in this definition, algorithms are particularly powerful tools when combined with computing power. The proliferation of computerized algorithms in business settings has occasionally led to unintended and injurious outcomes. This is perhaps most notable in relation to the algorithmic trading of securities. The 2010 ‘‘Flash Crash” of the United States (U.S.) financial markets, during which key …

Beyond Airspace Safety: A Feminist Perspective On Drone Privacy Regulation, Kristen Mj Thomasen

Canadian Journal of Law and Technology

No technology emerges in a social or legal vacuum. The laws and norms guiding acceptable uses of new technologies help to shape the ways in which these technologies benefit or disadvantage different individuals and communities. Recently, the impact of drones on women’s privacy has garnered sensational attention in media and popular discussion. Media headlines splash stories from drones spying on sunbathing or naked women and girls, to drones being used to stalk women through public spaces, to drones delivering abortion pills to women who might otherwise lack access. Yet despite this popular attention, and the immense literature that has emerged …

On The Double Chain Ladder For Reserve Estimation With Bootstrap Applications, Larissa Schoepf

Masters Theses

"To avoid insolvency, insurance companies must have enough reserves to fulfill their present and future commitment-refer to in this thesis as outstanding claims towards policyholders. This entails having an accurate and reliable estimate of funds necessary to cover those claims as they are presented. One of the major techniques used by practitioners and researchers is the single chain ladder method. However, though most popular and widely used, the method does not offer a good understanding of the distributional properties of the way claims evolve. In a series of recent papers, researchers have focused on two potential components of outstanding claims, …

Thrust Sensing For Small Uavs, Christopher Scott Marchman

Masters Theses

"Unmanned aerial vehicles (UAVs) have become prevalent in both military and civilian applications. UAVs have many size categories from large-scale aircraft to micro air vehicles. The performance, health, and efficiency for UAVs of smaller sizes can be difficult to assess and few associated instrumentation systems have been developed. Thrust measurements on the ground can characterize systems especially when combined with simultaneous motor power measurements. This thesis demonstrates the use of strain measurements to measure the thrust produced by motor/propeller combinations for such small UAVs. A full-bridge Wheatstone circuit and electrical resistance strain gauges were used in conjunction with constant-stress cantilever …

Exhumation Of The Nacimiento Block: A Thermochronologic Analysis, Lisa Marie Arnold Lori

Masters Theses

Sensitivity Analysis Of Geomechanical Parameters In A Two-Way Coupling Reservoir Simulation, Hector Gabriel Donoso

Masters Theses

"Currently reservoir simulators model geomechanical effects such as compaction, subsidence, fault reactivation, breach of the seal integrity, etc. using only the rock compressibility to change the pore volume. However, rock compressibility as a scalar quantity is unfit to represent the true rock mechanics in the reservoir. In order to accurately represent geomechanical effects in a reservoir simulation, a two-way coupling simulation of the stress analyzer and the reservoir simulator was done. Based on the poroelasticity theory during the production or depletion of the reservoir the porosity and permeability changed due to the stress or pore pressure changes.

A sensitivity analysis …

Event-Sampled Direct Adaptive Neural Network Control Of Uncertain Strict-Feedback System With Application To Quadrotor Unmanned Aerial Vehicle, Nathan Szanto

Masters Theses

"Neural networks (NNs) are utilized in the backstepping approach to design a control input by approximating unknown dynamics of the strict-feedback nonlinear system with event-sampled inputs. The system state vector is assumed to be unknown and an observer is used to estimate the state vector. By using the estimated state vector and backstepping design approach, an event-sampled controller is introduced. As part of the controller design, first, input-to-state-like stability (ISS) for a continuously sampled controller that has been injected with bounded measurement errors is demonstrated and, subsequently, an event-execution control law is derived such that the measurement errors are guaranteed …

Design And Fabrication Of A System For The Additive Manufacturing Of Transparent Glass, Luke John Gilbert

Masters Theses

"Despite glass' prevalence in the scientific and engineering community, very little research has been conducted attempting to additively manufacture (AM) glass. Even less research has been done on optically transparent glass. Glass’ material properties make it ineligible for most AM processes if the end result is to be transparent. Even small gas inclusions can cause large amounts of scattering. Additively manufacturing transparent glass brings the advantages found in other AM processes with the added benefit of having optical properties better than those found in polymers. Additively manufacturing glass also allows the optical properties of transparent parts to vary arbitrarily. This …

Music And The Child, Natalie Sarrazin

Milne Open Textbooks

Children are inherently musical. They respond to music and learn through music. Music expresses children’s identity and heritage, teaches them to belong to a culture, and develops their cognitive well-being and inner self worth. As professional instructors, childcare workers, or students looking forward to a career working with children, we should continuously search for ways to tap into children’s natural reservoir of enthusiasm for singing, moving and experimenting with instruments. But how, you might ask? What music is appropriate for the children I’m working with? How can music help inspire a well-rounded child? How do I reach and teach children …

Thresholding Techniques For Discrimination Of Seborrheic Keratosis From Melanoma In Dermoscopy Images, Pramada Kishtagari

Masters Theses

“Malignant melanoma is a very deadly form of skin cancer which has claimed many lives over the past few years. If detected early this can be cured, hence early detection of malignant melanoma is essential. Unfortunately melanoma is mimicked by seborrheic keratosis, a benign skin cancer. Identifying malignant melanoma as seborrheic keratosis using clinical diagnosis can prove fatal to the patient. To prevent such errors, dermoscopy, a common non-invasive skin imaging technique, is used which improves the diagnosis of these pigmented lesions by visualizing the morphological structures. This study proposes an automatic method by applying image processing techniques to aid …
