Deliver Us from Obscurity: How Persecution Shaped William Byrd into One of England’s Finest Composers
Get PDFBecause of the persecution and religious oppression William Byrd faced, his compositional process was forced to be more intricate, innovative, and creative. Consequently, he penned some of the greatest music England has ever seen. Elizabethan England’s history shows how the tenor of Byrd’s relationship with Elizabeth I is deeply ironic, as Elizabeth protected Byrd from the persecution that she afflicted upon him. Even though many of Byrd’s works appear docilely Anglican upon first glance, a deeper analysis reveals many hidden allusions to his Catholic beliefs, developing a masterful level of complexity to his compositions. Many of his motets had double meanings inherent in their composition. Byrd’s most exquisite music achieved that status because of his underlying expression of his non-compliant beliefs and spiritual character of musical inspiration
German Poetry in Musical Motion
Get PDFThe musical era of Romanticism leaped forward from the individuality of Beethoven and developed composers that were unafraid of expressing their passions through their music. The leading figures of Romanticism, like Schubert and Liszt, no longer saw themselves as servants of their audiences but instead made it their goal to show what they loved in their music. Even despite the stark individualism that was prevalent in this era, there was a shared passion many composers had that was able to unify them, a love for poetry. By studying emotive vocal genres like the German Lied as well as the influences of poetic literature on purely instrumental works, poetry is revealed to be a common trait in the Romantic era

Exploring a Smart Home Smoke Detector
Get PDFCommon household devices have become packed with technology including microphones, cameras, and even internet connectivity. While this technology provides numerous benefits, many consumers have concerns about the security and potential exploitation of these devices. Our team was provided with a smart home smoke detector by Ceaser Creek Software, our project sponsor. The team at CCSW had already gained access to the device\u27s memory and the ability to inject/execute custom code. Our team was tasked with reverse engineering the smoke detector in order to understand how the device works. Specifically, our team has worked to gain access to the microphone, record audio data, and send that information over the network. Our team performed static analysis of the device\u27s memory, dynamic analysis of running tasks, and ran custom code on the device. We successfully managed to create new tasks, keep the device awake while running code, and view data recorded by the microphone during a self-test. We are currently working to manually record audio and export that data over the network
Multi-Material Quasi-Zero Stiffness Vibration Isolators
Get PDFVibration-generating machines are ubiquitous in modern life, and it is often desirable to prevent the vibrations from being transmitted through the machine’s supports to protect either the supported object or nearby structures and equipment from excess shaking. A mounting system with a low stiffness is generally required to isolate a vibration source or receiver. Optimal isolation occurs by disconnecting the path altogether, resulting in zero stiffness, but this is not typically practical since the machine still needs to be supported. Quasi-zero stiffness (QZS) describes a property of a connection point where the stiffness is approximately zero at an operating point but becomes high if the object moves away from that point. This enables a mount to secure a vibrating object relatively in place while substantially reducing the vibrations transmitted through the mounts, and the mechanism works whether it is the base or the supported object that is vibrating. This project is seeking to extend prior work on a QZS mount concept that relies on large deformations of elastomeric beams to enhance its practicality and suitability for a variety of applications.
The specific goals of this project are to evaluate several materials as used in the mounts, explore manufacturing issues with casting and 3D printing processes, apply a multi-material design concept to increase the strength of a mount without losing its QZS properties, and apply the mount concept to a multi-mount system. Physical mechanical testing of various elastomeric materials is used to develop a nonlinear, hyperelastic material characterization for finite element (FE) simulations in both design and analysis of QZS mounts. Mechanical testing of individual mounts and mount systems demonstrates proof of concept and validates the existence of QZS properties seen in FE simulations for both multi-material and single-material mounts. Multi-axis stiffness properties are also evaluated in simulation and measurement for system design purposes, and dynamic testing is presented to characterize the damping in QZS isolation
Sketchy Driver
Get PDFCedarville’s cyber operations program requires students to learn how to interact with drivers in its Linux Systems Programming class. Historically, the class required students to complete a homework assignment in which they complete a driver for a virtual Linux-based device. However, this assignment proved both unideal (as a virtual device) and needlessly complex for its scope.
Our team’s goal was to develop a custom physical device and corresponding assignment to replace the previous device driver assignment. Our design criteria was as follows: a fun and simple physical device to interact with, the ability to use this device with a cloud-based virtual machine, an interactive driver, and a low manufacturing cost. In terms of manufacturing cost, our goal was to keep a reasonable cost for a set of roughly 20 units.
We decided to pursue an ESP32-S2 solution, with the goal of creating a USB Vendor-type device that could be easily passed through to a cloud VM with minimal user interaction. In an effort to create both a fun and focused assignment, we set developmental efforts on an Etch-a-sketch type device.
Our device consists of 4 main components: hardware, firmware, the device driver, and client-side software. We constructed a physical shell for the device using 3D printing, developed firmware to interact with the two integrated rotary encoders, created a driver to interface the device with the client, and built a software client program to display functionality of the device to the students.
Our assignment aspect focused on the device driver. We took our functioning device driver and pulled out pieces that we desired students to learn. Given the entire assignment, students should be able to understand how device drivers function, in how they interact with the physical device and the rest of the system itself
H3K27Ac Levels are Affected by Heat Stress and Anti-Mitotic Drugs in Tetrahymena Thermophila
Get PDFGene regulation is one of the most complex tasks to be undertaken by any eukaryotic cell, and a prime contributor to gene regulation is the post-translational modification of histone tails. Diffuse Intrinsic Pontine Glioma (DIPG) is an example of a cancer that occurs when one lysine, H3K27 on the tail of histone H3, is mutated to a methionine, making the usual post-translational modifications (methylation and acetylation) that occur at position 27 impossible. We believe that this lysine residue is critical for the regulation of cell division. Our hypothesis was that perturbations of cell division, as well as stress, will affect acetylation at H3K27. We also sought to find some of the binding partners that interact with H3K27ac by doing whole cell CO-IP. Our results show that stress and mitotic inhibitors affect acetylation levels of H3K27, and that proteins associated with DNA repair, transcription, RNA processing, and nuclear proteostasis associate with H3K7ac
