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,...
Resource Type:: Dissertation

Utilizing the thermodynamic properties of E85 to increase the specific efficiency of a high specific output single cylinder Formula SAE engine

Creator:: Duncan, Derek N.
Abstract:: Formula SAE is a collegiate engineering competition that has participants from around the globe. Of the 1000 points available throughout the event, 100 (10%) are dedicated to the fuel efficiency of the student built race cars. Competition rules allow either gasoline or E85, a mix of 85% ethanol and 15%...

Dynamics and control for spring-mass legged robots

Creator:: Vejdani Noghreiyan, Hamid Reza
Abstract:: The objective of this study is to propose control strategies for legged robots to walk and run naturally like humans and animals. To achieve this goal, we use the spring-mass model for the legged robots to be able to create the same dynamics in the leg as humans and animals....

Determination of cutting forces with asymmetric wedged blades

Creator:: Phan, Andrew Vinh
Abstract:: Cutting operations using blades appear in several different industries such as food processing, surgical operations, gardening equipment, and so forth. As our society continues to increase our technological prowess, there is an ongoing need to better understand the underlying causes of simple tasks such as cutting so that cutting operations...

Influence of subset size, shape and orientation on texture based digital image correlation

Creator:: Cui, Jianqing
Abstract:: Digital Image Correlation(DIC) is one of full-field strain measurement techniques devel- oped in recent decades, which has been well-demonstrated to conduct the mechanical properties study of solid materials, by collecting data using digital cameras. X-ray to- mography(CT) imaging helps the correlation techniques expanded to three dimensional investigation of materials, known...

Grasping complex casting shapes with an underactuated parallel jaw gripper on an industrial robot

Creator:: Carpenter, Ryan Joseph
Abstract:: Steel foundries are in great need of automation as current operations involve many hazardous manual tasks. Automating foundry operations is very challenging due to the variety of tasks that must be performed on physical objects that vary significantly in size, shape, and weight. This thesis focuses on robotically automating the...

A modeling and empirical study of a novel bimodal natural gas internal combustion engine with fuel compression capability

Creator:: Elgin, Robert C., III
Abstract:: Given the current abundant supply and cheap price of natural gas (NG) in the United States, there is a significant opportunity to use this fuel for transportation. However, there are few fueling stations for consumers. To address this need, a dual-mode engine has been developed where in one mode all...

Numerical design of a high-flux microchannel solar receiver

Creator:: Rymal, Charles
Abstract:: This thesis discusses the design of several microchannel solar receiver devices for use in CSP (concentrated solar power) using CFD (computational fluid dynamics) simulations. The goal is to demonstrate that, by taking advantage of the higher heat transfer coefficienct of microchannels, solar receivers can achieve higher efficiency than current receiver...
Resource Type:: Masters Thesis

Evaluation of Abaqus for simulating quasi-static Mode III shear of edge notched carbon fiber reinforced polymer panels

Creator:: Hyder, Imran
Abstract:: The ability to engineer stiffness and strength in any desired direction make composites an ideal material candidate for various applications when compared to their traditional isotropic counterparts. In spite of this, the ability to model the material response in composites has yet to be fully explored. Composite research largely focuses...
Resource Type:: Masters Thesis

Development of a Mobile Application for Android Platforms

Creator:: Hayden, Levi G.
Abstract:: The ability to develop mobile applications for smartphones and tablets is an increasingly valuable skill in today’s labor market. This thesis details the development of the mobile application Drone Drop from beginning to finish. I first describe the background research conducted to learn about programming languages and other tools used...
