Simulating Motion Success With Muscle Deficiency In A Musculoskeletal Model Using Reinforcement Learning, Daniel Castillo Aug 2023

Simulating Motion Success With Muscle Deficiency In A Musculoskeletal Model Using Reinforcement Learning, Daniel Castillo

Theses and Dissertations

Humans possess an extraordinary ability to execute complex movements, captivating the attention of researchers who strive to develop methods for simulating these actions within a physics-based environment. Motion Capture data stands out as a crucial tool among the proven approaches to tackle this challenge. In this research, we explore the effects of decreased muscle force on the body's capacity to perform various tasks, ranging from simple walking to executing complex jumping jacks. Through a systematic reduction of the allowed force applied to individual muscles or muscle groups, we aim to identify the threshold at which the body's muscles tolerate the …


Bird Mortality In The Human Built Environment, Stacie Schwartz Jun 2013

Bird Mortality In The Human Built Environment, Stacie Schwartz

Honors Theses

Human development is having a detrimental effect on bird populations around the world. One hundred million to one billion birds are killed every year from colliding with human-built structures. I explored factors influencing the inability of birds to avoid man-made structures. If we can better understand these reasons, we can find solutions to this problem. After a known bird avoidance method, fritted glass, was installed in the Wold building, I investigated whether this glass actually deters birds from striking windows. Strikes on windows were noted daily through observation of specific windows on campus. Results show that vegetation outside of windows …
