Viros i Martin, Antoni (2022-07-20)The popularity of Cognitive Assistants, defined as intelligent AI agents that enhance human capabilities and interact through natural language, has surged in the last decade. Recent advances in natural language understanding ...
-
Davis, Allen Miller (2022-11-14)Mission-adaptive aerostructural design considers the alteration of structural geometries to im-prove multi-objective performance in multiple aerodynamic environments. Geometric structural alterations can be tailored to ...
-
Bera, Ritwik (2022-01-11)Recent successes in the field of robot learning have combined reinforcement learning algorithms and deep neural networks. Yet, reinforcement learning has not been widely applied to robotics and real world scenarios. This ...
-
Missel, Jonathan William (2013-04-25)Low Earth Orbit is over-cluttered with rogue objects that threaten existing technological assets and interfere with allocating new ones. Traditional satellite missions are not efficient enough to collect an appreciable ...
-
Peck, Caleb Hamilton (2023-05-11)Solutions to differential equations form the bedrock of many guidance, navigation and control operations, such as state propagation and optimal control. While analytical solutions exist for a variety of problems, complex ...
-
Restrepo, Carolina Isabel (2009-05-15)The new vision for space exploration will focus on sending humans to the moon and eventually to Mars. This endeavor presents new challenges that are critically different from the past experience with robotic missions to ...
-
Tandale, Monish Deepak (Texas A&M University, 2007-09-17)The adaptive dynamic inversion control methodology uses dynamic inversion to calculate the control, and adaptation to compensate for the errors in the inversion due to model uncertainties. Traditionally, adaptive control ...
-
Runco, Carl Christopher (2022-04-21)Micro air vehicles are inherently susceptible to wind because of reduced inertia and have lower aerodynamic efficiency due to the poor performance of airfoils at low Reynolds numbers. Cyclorotors can potentially overcome ...
-
Beckett, Andrew 1984- (2012-11-12)Intelligence, surveillance, and reconnaissance unmanned aircraft systems (UAS) are the most common variety of UAS in use today and provide invaluable capabilities to both the military and civil services. Keeping the sensors ...
-
Fisher, James Robert (Texas A&M University, 2005-02-17)This thesis describes the implementation of Yaos adaptive robust control to an aircraft control system. This control law is implemented as a means to maintain stability and tracking performance of the aircraft in the ...
-
Narang, Anshu (2012-09-18)This dissertation addresses the control problem for the general class of control non-affine, non-standard singularly perturbed continuous-time systems. The problem of control for nonlinear multiple time scale systems is ...
-
Chandra, Manik (Texas A&M University, 2007-04-25)This work presents a control algorithm developed from the mammalian emotional processing network. Emotions are processed by the limbic system in the mammalian brain. This system consists of several components that carry ...
-
Franklin, David Joseph (2020-03-30)This thesis describes a novel concept called "Hard Truck Platooning" that achieves platooning between commercial tractor trailers with the aid of a smart tow hitch between the trailer of the leading vehicle and the tractor ...
-
Morris, Jeffery C. (2010-01-14)Automated spacecraft docking is a concept of operations with several important potential applications. One application that has received a great deal of attention recently is that of an automated docking capable unmanned ...
-
Henrickson, James V (2014-04-28)Shape memory alloys are capable of delivering advantageous solutions to a wide range of engineering-based problems. Implementation of these solutions, however, is often complicated by the hysteretic, non-linear, thermomechanical ...
-
El Ashkar, Joseph Elie (2023-08-04)The energy density limitations of current battery technologies constrain reconnaissance missions carried out by small unmanned aerial systems (UAS). Even in dangerous environments, limited range requires many UAS to return ...
-
Jares, Garrett (2023-01-04)This work investigates and develops a novel method of cyberattack which aims to take control of an autonomous aerospace system by injection of false measurement data. This work demonstrates that an attacker can use ...
-
Savage, Elizabeth (Texas A&M University, 2004-09-30)The proposed project is the simulation of a system to search for air vehicles which have splashed-down in the ocean. The system comprises a group of 10+ autonomous underwater vehicles, which cooperate in order to locate ...
-
Lee, Sang Hyun (2015-04-28)Recently developed satellite systems require a group of satellites acting in concert with one another to meet mission objectives. Specifying a constellation by defining all the orbit elements for each satellite is complex, ...
-
Ding, Yuanyuan (2009-05-15)The existing air transportation system is approaching a bottleneck because its dominant huband- spoke model results in a concentration of a large percentage of the air traffic at a few hub airports. Advanced technologies ...
