Safe Navigation Of Quadruped Robots Using Density Functions, Andrew Zheng
Safe Navigation Of Quadruped Robots Using Density Functions, Andrew Zheng
All Theses
Safe navigation of mission-critical systems is of utmost importance in many modern autonomous applications. Over the past decades, the approach to the problem has consisted of using probabilistic methods, such as sample-based planners, to generate feasible, safe solutions to the navigation problem. However, these methods use iterative safety checks to guarantee the safety of the system, which can become quite complex. The navigation problem can also be solved in feedback form using potential field methods. Navigation function, a class of potential field methods, is an analytical control design to give almost everywhere convergence properties, but under certain topological constraints and …

A Study Of 5g Cellular Connectivity To Unmanned Aerial Vehicles, Jackson Murrin
All Theses
The market of unmanned aerial vehicles (UAVs) has seen significant growth in the past ten years on both the commercial and military sides. The applications for UAVs are endless and options by manufacturers allow users to modify their drones for their specific goals. This industry has opened up the excitement of piloting vehicles in the air, photography, videography, exploration of nature from a different point of view and many other hobbies assisted by the emergence of UAVs. The growth of this industry coincides with the roll out of new 5G cellular network technology. This upgrade in cellular network infrastructure allows …
The Extent Of Drone Education Being Taught In Asc Schools To 4-Year Construction Students, Cheran Teja Dumpati
The Extent Of Drone Education Being Taught In Asc Schools To 4-Year Construction Students, Cheran Teja Dumpati
All Theses
The technology of Unmanned Aircraft Systems (UAS) is growing rapidly in many fields and has become one of the skills in demand in the industry. Universities are one of the primary sources of teaching drone technology with a career-oriented approach. The goal of this study is to investigate the content of the drone curriculum being taught in Associated Schools of Construction (ASC) schools. This includes the topics covered, practical training offered, and the key deliverables taught. This information serves as a foundation for the schools that are looking forward to start drone courses in their department. The research found that …
Tradespace Exploration Of A Uav Conceptual Design Using Model-Based Systems Engineering, Ayan Srivastava
Tradespace Exploration Of A Uav Conceptual Design Using Model-Based Systems Engineering, Ayan Srivastava
All Theses
The objective of this research is to apply model-based systems engineering approaches to the conceptual design of unmanned aerial vehicles. This is accomplished by evaluating the models of aircraft performance, extracting input and output parameters from the models, creating chains of models, and implementing the models in the MATLAB programming language. By following this process, it is possible to identify the global parameters that remain constant across models, the shared input parameters, the dependencies between models, and the feedback loops with the systems models.
The models are currently implemented in two files using Microsoft MS Excel, one is focused on …
Experimental Study Of The Three-Stream Scalar Mixing In A Turbulent Coaxial Jet, Matthew Dinger
Experimental Study Of The Three-Stream Scalar Mixing In A Turbulent Coaxial Jet, Matthew Dinger
All Theses
In the present study we investigate three-stream scalar mixing in a turbulent coaxial jet. In
this flow the center jet and the annulus, consisting of acetone-doped air and ethylene respectively, are
mixed with the co-flow air. A unique aspect of this study compared to previous studies of three-scalar
mixing is that two of the scalars (the center jet and air) are separated from the third (annulus);
therefore, this flow better approximates the mixing process in a nonpremixed turbulent reactive
flow. Planar laser-indiced fluorescence and Rayleigh scattering are employed to measure the mass
fractions of the acetone-doped air and ethylene, respectively. …
