Improving Torque Distribution Of The Baja Car's Drive Shaft, Natalie E. Falerios

Senior Honors Theses and Projects

This honors thesis analyzes torque variation in the drive shaft system of the Baja SAE vehicle, with a focus on the effects of universal joint (U-joint) geometry and phasing in an inherited and new drive shaft design. The original drivetrain was inherited from a previous team and affected the seat placement that did not comply with the Baja SAE rules. This resulted in a redesign of the drive shaft and evaluation of both the inherited and redesigned configurations’ performance. An initial experiment was created and attempted to analyze the torque variation in the drive shaft, however, there were time constraints …

Waveforms For Next Generation Non-Stationary Channels, Zhibin Zou

Electronic Theses & Dissertations (2024 - present)

Waveform design aims to achieve orthogonality among data signals/symbols across all available Degrees of Freedom (DoF) to avoid interference while transmitted over the channel. Precoding involves the decomposition of the channel matrix into orthogonal components for the purpose of constructing a precoding matrix that is then combined with the data signal to achieve orthogonality in the spatial dimension. On the other hand, modulation uses orthogonal carriers in a certain signal space to carry data symbols with minimal interference from other symbols.

Iverson, Andrew Fry

Faculty Publications

The mill behavior of a 312 Combustion Engineering Raymond Bowl Mill was studied with five blends of Utah bituminous coal and steam-exploded woody biomass, ranging from 100 % coal to 100 % biomass. Mill power consumption increased with biomass content, peaking at 187 % of the power required for 100 % coal before the mill faulted at 100 % biomass. After repositioning the rollers, power consumption for 100 % biomass decreased by 13 % compared to 100 % coal. SEM images revealed that milled biomass particles were non-spherical, indicating some fibrous structure remained post steam-explosion. The particle size distribution (PSD) …
