This project was to extend Jarvis by adding home control and a natural voice-activated user-interface system.

Point-N-Share Binoculars, James Sargent, Zachary Hyatt

Electrical and Computer Engineering

Point-n-Share Binoculars are a pair of smart binoculars that can share locations. This is accomplished by using fused sensor data from

• Global Positioning System (GPS)
• Laser Range Finder (LRF)
• Inertial Measurement Unit (IMU)

Using an LRF, the distance between the user and target is determined. The pitch and heading of the binoculars is collected from the IMU. Using trigonometry, the true difference in GPS coordinates between the user and the target is calculated. That difference is then added to the user’s GPS coordinates to determine the coordinates of the target.

The GPS coordinates of the marked location are then transmitted …

Onboard Load Sensor For Use In Freight Railcar Applications, Constantine Tarawneh, Jazmin Ley, Dylan Blackwell, Stephen Crown, Brent Wilson

Mechanical Engineering Faculty Publications

Approximately 40% of intercity freight transportation occurs by rail, making it the most widely used method of transporting large commodities. This trend is expected to persist over the next thirty years as our highway systems are strained and experiencing increased congestion and costly delays. Currently, the load of freight railcars is typically measured by weighbridges or retrofitted tracks at isolated locations. This practice is not efficient and limited by the fact that the load of the railcar cannot be monitored continuously, not to mention the inherent inaccuracies of such systems. Hence, there is great merit for an onboard load sensor …

Measuring The Effects Of High-Altitude Flight And Upper Atmospheric Radiation On Muscle Cells, Lori M. Caldwell, Annelise Dykes, Katherine Glaittli, Charles Harding

Biological Engineering

As longer space missions become more desirable to public and private institutions, the physiological impact on astronauts must be considered. One of the primary concerns for those spending time in low-gravity environments is the eventual loss of muscle tissue due to atrophy, because a decreased force pulling on muscle fibers leads to marked atrophy in as little as nine days¹ (Fig. 1). This debilitating loss of muscle makes it difficult for homeward-bound astronauts, who are returning to full gravity, to regain their physical strength.

Non-Invasive, Inductive Electrodes For Application In Brain Computer Interfaces, Colin Ecsedy, Justin Marriott, Andrew Parker

Biological Engineering

Brain-Computer Interfaces (BCI) have proved to be a major factor in facilitating motor recovery, recovery of hearing and vision loss, and other debilitating conditions and diseases (Nicolas-Alonso, 2012). This is accomplished by measuring neurological signals and interpreting that information into a desired action. The most common method of sensing neurological activity for BCI is by either surface or implanted electrodes that are either prone to unreliability or are dangerously invasive (Alpert, 2008). Part of this unreliability is based on the low specificity of the electrode method, requiring many pairs of electrodes to accurately detect signals in a particular area. By …

This work was done using recombinant spider silk proteins (rSSps) produced in transgenic goat milk.

Recently, spider silks have been recognized for their biocompatibility and lack of immunogenicity. Their incredible strength and ability to safely be in contact with the body makes them highly desirable for use …

Synthesizing Microcarriers As A Platform For The Pharmaceutical Delivery Of Quercetin For Antiviral Applications, Taylor Eggertsen, Arther Hart, William Johnson

Biological Engineering

This project aims to increase quercetin bioavailability and antiviral activity against cytomegalovirus (CMV). CMV is the leading viral cause of birth defects in the U.S. Ganciclovir, the current treatment for CMV infection, exhibits cytotoxicity in pregnant women and other immunocompromised populations. Quercetin is a naturally derived compound with antioxidant, anti-cancer, antiviral and anti-inflammatory properties and exhibits anti-CMV activity (Cotin, 2012). Low solubility and rapid metabolic breakdown result in low bioavailability, however (Thilakarathna, 2013). Pluronic-F127 capped poly(lactic-co-glycolic acid) (PLGA), and chitosan-capped alginate microbeads are investigated as microcarriers to provide time-release antiviral treatment for congenital CMV. Quercetin, PLGA, chitosan, alginate, and Pluronic …

Minimization Of Quantum Circuits Using Quantum Operator Forms, Martin Lukac, Michitaka Kameyama, Marek Perkowski, Pawel Kerntopf

Electrical and Computer Engineering Faculty Publications and Presentations

In this paper we present a method for minimizing reversible quantum circuits using the Quantum Operator Form (QOF); a new representation of quantum circuit and of quantum-realized reversible circuits based on the CNOT, CV and CV† quantum gates. The proposed form is a quantum extension to the well known Reed-Muller but unlike the Reed-Muller form, the QOF allows the usage of different quantum gates. Therefore QOF permits minimization of quantum circuits by using properties of different gates than only the multi-control Toffoli gates. We introduce a set of minimization rules and a pseudo-algorithm that can be used to design circuits …
