Changes in climate caused by increased concentrations of carbon dioxide (CO₂) in the Earth’s atmosphere have led land and ocean surface temperatures to increase by 0.85°C and sea level to increase by 19 cm relative to preindustrial times. Global climate change will lead to further alterations in mean temperature and...
Bipedal locomotion is a complex phenomenon to understand and control, making it difficult for legged robots to achieve the speed, agility, efficiency, and robustness of their animal counterparts. This thesis argues for the use of numerical optimization to investigate and implement bipedal control as it applies to biology, dynamical models,...
There is a fundamental distortion in our understanding of Native people, especially Native women. This distortion is rooted in imperialism and the colonization of Native lands and has created a dominant/subordinate relationship between Non-Native/Native people. Anthropological life history research has traditionally reflected this relationship. As a Native woman, the author...
