Making a massacre: The 1622 Virginia “massacre,” violence, and the Virginia Company of London’s corporate speech
No full textWhen news reached London that the Powhatan Confederacy had mounted an assault on the Virginia colony in March 1622, the loss of colonists, infrastructure, and goods came to the Virginia Company of London as crisis among crises. Colonists were resisting efforts to diversify the colony’s commodities and shareholders were growing impatient with the lack of dividends. The Virginia Company responded to news of the attack by embarking on a print publication campaign to depict the violence not as a mere incursion but as a “massacre.” This article
examines this publication campaign to argue that the Virginia Company leveraged its corporate rhetoric to convert the violence of the so-called massacre into a dividend for shareholders and a vindication of the company’s economic program. Ultimately, the article argues that we
must read the Virginia Company’s publications through the lens of corporate strategy—not as reportage but as active efforts to generate capital.Journal ArticlePublishe

SALDI-MS of real world samples
No full textSurface-assisted laser desorption/ionization mass spectrometry (SALDI-MS) is a method of mass spectrometry, ideal for the low mass range, as it reduces fragmentation and helps with clarity of sample analysis. Projected applications of this technology can be seen in medical and drug research.
• Quinine is a small, organic biomolecule (molecular weight 325 g/mol) that is derived from the bark of the cinchona plant. Native to the Americas, is historically used as an anti-malaria, but in recent years has emerged in drug analyses of heroin. Dealers dilute the sample in quinine, which has a similar bitter taste, as a way to conserve supply.
Due to its variety of functional groups and reactive units, quinine has many side effects. As of April 2019, the FDA limits quinine to 83ppm in beverage samples. Coupled with its increased use in illegal drugs and its regulated recreational use, a new, quick and easy method of detection is needed for its analysis.
• Quinine is commonly found dissolved in carbonated beverages to make tonic water.
• Transition metal oxide (TMOs) nanoparticles are used in SALDI-MS because they require minimal sample preparation, have large surface area to sample rations (which helps with desorption/ionization), and they are compatible with a wide range of different samples
Multimedia principles & the Pickens Multimedia Studio
No full textMy research focuses on the goals of the newly created Pickens Multimedia Studio at the Academic Excellence in Instructional Strategies Office (AXIS) within the College of Education and Professional Studies. The Pickens Studio aims to provide faculty end-to-end support with incorporating multimedia into their coursework. We are working to provide support in adherence to Mayer’s Multimedia Principles so that faculty can provide students with a robust and effective online learning environment.Graduate Research PresentationDr. Nancy Hasting

Coupling data-driven and model-based methods to improve fault diagnosis
No full textMonitoring a system is often not an easy task and the best approach to address it would be to develop a monitoring system that uses data, expert knowledge, and mathematical models. Combining these three sources of information on the system is often unpractical of various reasons such as in complex systems. In this paper, a hybrid method for diagnosing single and multiple simultaneous faults, while considering unknown operating conditions, is proposed. This method consists of a Bayesian classifier combining statistical decisions and fault signature matrix. Several scenarios of operating conditions are simulated for illustrative purposes. The results, in terms of classification rates, show the interest of the hybrid classifier. It demostrates higher capabilities to isolating multiple simultaneous faults that the purely data-driven classifier fails to accomplish.Journal ArticlePreprint - online ahead of prin
Design of a nested saturation controller with improved wind disturbance rejection for UAVs
No full textThis paper presents an augmented nested saturation controller for Unmanned Aerial Vehicles (UAVs) to achieve steady state wind rejection. The work improves a control law that is not able to reject wind disturbances for UAV dynamics by introducing proportional and derivative multipliers and a saturation element. The augmented nested saturation controller is able to reject ambient wind disturbances and limit uncontrollable spikes in state error when there is a strong wind gust. The controller is evaluated on path following tasks with both circular and linear trajectories. The experiments are carried out on Software-in-the-Loop simulation on Gazebo which offers realistic dynamic behavior. The results show that developed approach successfully rejected steady winds up to 1.3N. The augmented controller achieved stability with 1.3N for a straight and circular path where the original nested controller is not able to do so.Conference Pape
