Selective Laser Melting of H13 Tool Steel for Rapid Tooling

Creator:: Katancik, Michael
Abstract:: The current knowledge on the microstructural evolutions and mechanical properties of selective laser melting (SLM) produced H13 tool steel components is limited. This research is focused on optimization of SLM processing parameters for H13 tool steel and investigation of microstructure and mechanical properties of H13 tool steel components after SLM...

Developmental effects of micro- and nanoscale tire particles and recycled rubber on zebrafish

Creator:: Mottern, Taylor H.
Abstract:: Plastics have become an essential part of everyone lives, found in almost every product made today. Tires only make up a fraction of these products but as their use increasing so does the microplastics that flake off. Many studies have evaluated the toxic effects of tire particles on aquatic environments...

Radiation Emissions from Turbulent Premixed Jet-A/Air Flames Diluted with Combustion Products

Creator:: Hoter, Zohar R.
Abstract:: Heat flux measurements of radiation emissions from turbulent premixed flames diluted with N 2 and CO 2 were taken to identify sensitivities of radiation heat loss to diluent fraction and species. This work is motivated by the desire to better characterise radiant heat transfer in the presence of combustion products,...

The Adverse Effects of Diurnal Light Exposure on Aging Drosophila melanogaster

Creator:: Nash, Trevor N.
Abstract:: The proliferation of light emitting diodes (LEDs) are increasing human light exposure, yet the long-term effects of such exposure remains unknown. The current study aims to address this by measuring the longevity of Drosophila melanogaster kept in several light conditions. Initial longevity testing determined that flies kept in daily light-dark...

Active Control of Passive Dynamics for Ground Disturbance Rejection

Creator:: Koepl, Devin N.
Abstract:: We present a model for running that combines active control with passive dynamics, in an attempt to approach the economy and robustness of animal running. Our work is inspired by examples of guinea fowl encountering an unexpected drop in ground surface, with little a ect on their running gait. Previous...

Light Transmittance Properties of Biological Tissues of the Red-sided Garter Snake, Thamnophis sirtalis parietalis, Between 450 and 850 Nanometers

Creator:: Bixby, Eric M.
Abstract:: Using a spectrometer and photomultiplier tube, I measured the electromagnetic radiation transmittance properties of three types of tissue-- ventral skin, cardiac muscle, and liver tissue--in the red-sided garter snake Thamnophis sirtalis parietalis between the wavelengths of 450 and 850 nanometers (nm). Control readings were taken using a 10⁻² neutral density...

Bait and Trap Design Preferences for Drosophila suzukii

Creator:: Marcus, Monica H.
Abstract:: Knowledge of Drosophila suzukii's preference for an attractive trap design and bait can be used to improve detection and management of this new invasive fruit pest. Desired trap and bait attributes include: high D. suzukii capture and species specificity; early-season detection prior to significant crop damage; higher capture of females...

Preserving the Planar Dynamics of a CompliantBipedal Robot with a Yaw-Stabilizing Foot Design

Creator:: Abate, Andrew M.
Abstract:: The ATRIAS agile humanoid robot, along with a number of other spring-mass walking machines, currently have two instabilities: one resulting from inertial forces on the torso which cause the robot to spin like a top, and another resulting from stiff ground collisions which cause chattering of the point-contact toes. This...
