Software Updates To A Multiple Autonomous Quadcopter Search System (Maqss), Jared Speck, Toby Chan May 2017

Software Updates To A Multiple Autonomous Quadcopter Search System (Maqss), Jared Speck, Toby Chan

Computer Engineering

A series of performance-based and feature implementation software updates to an existing multiple vehicle autonomous target search system is outlined in this paper. The search system, MAQSS, is designed to address a computational power constraint found on modern autonomous aerial platforms by separating real-time and computationally expensive tasks through delegation to multiple multirotor vehicles. A Ground Control Station (GCS) is also described as part of the MAQSS system to perform the delegation and provide a low workload user interface. Ultimately, the changes to MAQSS noted in this paper helped to improve the performance of the autonomous search mission, the accuracy ...


Implementing Software Lab At Hackathons, Istvan Gates Jan 2017

Implementing Software Lab At Hackathons, Istvan Gates

Williams Honors College, Honors Research Projects

Hackathons are events where groups of college students have 24 hours to build up a any project, using Computer Science and Electrical Engineering skillsets. These events are typically hosted on college campuses, and attract over 200 students per event. Each student brings 2 devices - their phone, and their laptop. That means that 400 devices are connected to a University venue's Internet network, commonly overloading it. Software Lab alleviates this overloading by providing an abstracted NAS node network for events. Software Lab guarantees speeds of at least 100 mbits/s, and provides a 8-10x improvement on download speeds over the ...


Novel Mechanisms Underlying Warm-Up And Percussion Myotonia In Myotonia Congenita, Kevin Richard Nnovak Jan 2017

Novel Mechanisms Underlying Warm-Up And Percussion Myotonia In Myotonia Congenita, Kevin Richard Nnovak

Browse all Theses and Dissertations

Patients with myotonia congenita have muscle hyperexcitability due to loss-of-function mutations in the ClC-1 chloride channel in skeletal muscle, which causes spontaneous firing of muscle action potentials (myotonia), producing muscle stiffness. Triggers for myotonia can occur voluntarily at the neuromuscular junction or involuntarily by striking the muscle with a reflex hammer (percussion myotonia). In patients, muscle stiffness lessens with exercise, a change known as the warm-up phenomenon. Our goal was to identify the mechanism underlying warm-up and percussion myotonia and to use this information to guide development of novel therapies. To determine these underlying mechanisms, we used a drug to ...
