The Effect Of Neurostimulation On Ischemic Pain And Methods Of Assessing Pain, Kaylee Keck
Biomedical Engineering
Peripheral arterial disease (PAD) impacts approximately eight million people in the United States [1]. Disease progression leads to chronic ischemic pain, hindering quality of life. Pharmaceuticals are a typical treatment for pain associated with PAD; but as few as 30% of patients have a significant reduction of pain (≥50%) [2].
Neurostimulation is commonly used as a treatment for various diseases and injuries, including Parkinson’s disease and sports-related back and knee injuries [2]. The objective of the study was to explore neurostimulation and its effect on pain and paresthesia for a model of acute peripheral ischemia in young college students.

A Feed Forward Circuit For Jitter Attenuation On High-Speed Digital Signals, Eric Rule
A Feed Forward Circuit For Jitter Attenuation On High-Speed Digital Signals, Eric Rule
Electrical Engineering
In the age of high-speed digital circuitry, there exists a need for clean, precise clock signals. In generating and distributing clock signals throughout a circuit, unwanted jitter can become a serious issue. A common technique for attenuating jitter uses phase-locked-loops to treat the signal, but as the clock frequency increases, so does the cost and complexity of the designs. Following the research completed by Dr. Tina Smilkstein [1], this project examines a purely feed-forward technique for attenuating jitter that is low-complexity and robust, and aims to design an integrated circuit that implements the technique.

Utilization Of High Efficient Single Phase Motor, Kevin Hua
Utilization Of High Efficient Single Phase Motor, Kevin Hua
Electrical Engineering
A Smith Motor is a three phase induction motor that has shunt capacitors parallel to its induction coils. The shunt capacitors provide balance and allow the motor to operate using a single phase power supply. Preliminary studies show that the Smith Motor is more efficient than a single phase induction motor powered by a single phase power supply, but less efficient than a three phase induction motor powered by a three phase power supply. The Smith Motor’s advantage is its ability to operate from a single phase power source instead of having a three phase power source installed. Its limitation …
