Range of motion of beetle body as a function of foot positions

Creator:: Foo, Chee Kit
Abstract:: This thesis presents a method for determining range of body motion for a walking machine with feet fixed on the ground. The darkling beetle was selected as the sample subject in this study. A closed form inverse kinematic solution is used to determine if a point in space is within...

A simplified dynamic model of the hind leg of a beetle during step initiation

Creator:: Mallysetty, Venkata Ramana
Abstract:: This thesis investigates a simple dynamic model of the hind leg of a beetle during initiation of a step. The primary assumption was that the full load of the body was carried on the hind leg during this time. That is, the only forces on the body were that of...

Detection and analysis of separated flow induced vortical structures

Creator:: Snider, Stephen David Louis
Abstract:: Flow separation is an important phenomenon in fluid dynamics because of the effect it has on lift and drag on immersed bodies. Areas of swirl within a separated flow region may have a distinct effect on the surface forces, modifying the lift and drag characteristics. A correlation between the passage...

Modeling innovativeness in consumer products with the influence of environmental sustainability

Creator:: Gilchrist, Brady
Abstract:: This thesis is the result of two research publications, which together form a framework for the evaluation of product innovativeness with potential future applications to early design. Innovation is a challenging concept to quantify. Experts seemingly have a grasp of what innovation is when they see it, however this evaluation...

From running birds to walking robots : optimization as a unifying framework for dynamic bipedal locomotion

Creator:: Hubicki, Christian M.
Abstract:: 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,...

Single Phase and Flow Boiling Heat Transfer and Flow Characterization in Microscale Pin Fin Heat Sinks

Creator:: Rasouli, Erfan
Abstract:: The ever increasing requirements for heat dissipation in various thermal management applications such as computer chip cooling and high power electronics have necessitated the need for novel thermal management techniques. Thermal management using heat sinks with microscale features is amongst the prominent techniques developed over the past two decades. In...

DNS study of Particle-bed-Turbulence Interactions in Oscillatory Flows

Creator:: Ghodke, Chaitanya Deepak
Abstract:: Turbulent flows over rough surfaces are encountered in many engineering and geophysical applications. Flows of this nature, due to their increasing technological interests, have been a subject of rigorous investigation in recent years. Of the particular interest to the oceanographic community is the study of turbulent oscillatory flow over rough...

Modeling in-situ vapor extraction during flow boiling in microscale channel

Creator:: Salakij, Saran
Abstract:: In-situ vapor extraction is performed by applying a pressure differential across a hydrophobic porous membrane that forms a wall of the channel as a means of reducing the local quality of flow boiling within the channel. As the local quality is reduced, the heat transfer capability can be improve while...
