▼ The use of electrical vertical takeoff and landing (eVTOL) aircraft to provide efficient, high-speed, on-demand air transportation within a metropolitan area is a topic of increasing interest, which is expected to bring fundamental changes to the city infrastructures and daily commutes. NASA, Uber, and Airbus have been exploring this exciting concept of Urban Air Mobility (UAM), which has the potential to provide meaningful door-to-door trip time savings compared with automobiles. However, successfully bringing such vehicles and airspace operations to fruition will require introducing orders-of-magnitude more aircraft to a given airspace volume, and the ability to manage many of these eVTOL aircraft safely in a congested urban area presents a challenge unprecedented in air traffic management. Although there are existing solutions for communication technology, onboard computing capability, and sensor technology, the computation guidance algorithm to enable safe, efficient, and scalable flight operations for dense self-organizing air traffic still remains an open question. In order to enable safe and efficient autonomous on-demand free flight operations in this UAM concept, a suite of tools in learning-based perception and control systems with stress testing for safe autonomous air mobility is proposed in this dissertation. First, a key component for the safe autonomous operation of unmanned aircraft is an effective onboard perception system, which will support sense-and-avoid functions. For example, in a package delivery mission, or an emergency landing event, pedestrian detection could help unmanned aircraft with safe landing zone identification. In this dissertation, we developed a deep-learning-based onboard computer vision algorithm on unmanned aircraft for pedestrian detection and tracking. In contrast with existing research with ground-level pedestrian detection, the developed algorithm achieves highly accurate multiple pedestrian detection from a bird-eye view, when both the pedestrians and the aircraft platform are moving. Second, for the aircraft guidance, a message-based decentralized computational guidance algorithm with separation assurance capability for single aircraft case and multiple cooperative aircraft case is designed and analyzed in this dissertation. The algorithm proposed in this work is to formulate this problem as a Markov Decision Process (MDP) and solve it using an online algorithm Monte Carlo Tree Search (MCTS). For the multiple cooperative aircraft case, a novel coordination strategy is introduced by using the logit level-k model in behavioral game theory. To achieve higher scalability, we introduce the airspace sector concept into the UAM environment by dividing the airspace into sectors, so that each aircraft only needs to coordinate with aircraft in the same sector. At each decision step, all of the aircraft will run the proposed computational guidance algorithm onboard, which can guide all the aircraft to their respective destinations while avoiding potential conflicts among them.

▼ This dissertation focuses on the development of magnetic resonance imaging (MRI)-guided microwave thermal therapy systems for driving experimental studies in small animals, and to experimentally validate computational models of microwave ablation, which are widely employed for device design and characterization. MRI affords noninvasive monitoring of spatial temperature profiles, thereby providing a means to to quantitatively monitor and verify delivery of prescribed thermal doses in experimental studies and clinical use, as well as a means to validate thermal profiles predicted by computational models of thermal therapy. A contribution of this dissertation is the development and demonstration of a system for delivering mild hyperthermia to small animal targets, thereby providing a platform for driving basic research studies investigating the use of heating as part of cancer treatment strategies. An experimentally validated 3D computational model was employed to design and characterize a non-invasive directional water-cooled microwave hyperthermia applicator for MRI guided delivery of hypethermia in small animals. Following a parametric model-based design approach, a reflector aperture angle of 120°, S-shaped monopole antenna with 0.6 mm displacement, and a coolant flow rate of 150 ml/min were selected as applicator parameters that enable conformal delivery of mild hyperthermia to tumors in experimental animals. The system was integrated with real-time high-field 14.1 T MRI thermometry and feedback control to monitor and maintain target temperature elevations in the range of 4 – 5 °C (hypethermic range). 2 - 4 mm diameter targets positioned 1 – 3 mm from the applicator surface were heated to hyperthermic temperatures, with target coverage ratio ranging between 76 - 93 % and 11 – 26 % of non-targeted tissue heated. Another contribution of this dissertation is using computational models to determine how the fibroids altered ablation profile of a microwave applicator for global endometrial ablation. Uterine fibroids are benign pelvic tumors located within the myometrium or endometrium,and may alter the profile of microwave ablation applicators deployed within the uterus for delivering endometrial ablation. A 3D computational model was employed to investigate the effect of 1 – 3 cm diameter uterine fibroids in different locations around the uterine cavity on endometrial ablation profiles of microwave exposure with a 915 MHz microwave triangular loop antenna. The maximum change in simulated ablation depths due to the presence of fibroids was 1.1 mm. In summary, this simulation study suggests that 1 – 3 cm diameter uterine fibroids can be expected to have minimal impact on the extent of microwave endometrial ablation patterns achieved with the applicator studied in this dissertation. Another contribution of this dissertation is the development of a method for experimental validation of 3D transient temperature profiles predicted by computational models of MWA. An experimental platform was developed integrating custom… Advisors/Committee Members: Punit Prakash.

▼ Healthy pre-natal development of the mammalian visual system requires that retinal ganglion cell (RGC) axons navigate a precise path to their targets in the thalamus and superior colliculus by making a precise series of turns determined by the complex interactions between growth cone and extracellular environment. One important choice point for RGC axons is the crossing of the midline at the optic chiasm, where ipsilateral/ contralateral sorting takes place. In this thesis a novel image analysis method using steerable filters for quantifying the gross orientation and turning of axons from a static image (such as from DiI filled axons) is presented. This method was applied to understanding Slit dependent axon guidance at the mouse optic chiasm. It was possible to quantify the differences at the chiasm between the wildtype and various classes of mutants involving heterzygous or homozygous knockout of the Slit1 and the Slit2 genes. Assessment was in terms of the spatial distributions in axon density and axon orientation as derived from DiI labeled RGCs originating from one eye. The animals were assessed at embryonic day 13.5. To my knowledge this is the first quantification of its kind in the field of axon guidance. It was found that there were strong statistical differences from wildtype in both the Slit1-/-;Slit2-/- and Slit1+/+;Slit2-/- knockouts in terms of both axon density and axon orientation across large extents of the chiasm. In both these knockouts it was found that the changes in axon density were localised to the anterior region of the chiasm, but the changes in axon orientation were spread across almost the entire extent of the chiasm. No other combination of the Slit1 and Slit2 knockouts for which embryos could be generated showed significant differences from wildtype in terms of spatial changes in axon density or axon orientation. No embryos were generated for the Slit1+/-;Slit2-/- combination. No changes in the spatial distribution of axon density or axon orientation were found between the Slit1-/-;Slit2-/- and Slit1+/+;Slit2-/- knockouts, suggesting that in terms of these two quantities, the two phenotypes are indistinguishable. This evidence suggests that the role of Slit2 is more important than the role of Slit1 at the optic chiasm in terms iii of axon guidance. In addition, the gradients of mRNA expression of Slit1 and Slit2 were quantified using in situ hybridisation, and these data were used to compare the mRNA gradients with the orientation and turning of axons in both the wildtype and Slit1/Slit2 knockout chiasms. Although this provided a powerful visualisation tool, no simple mathematical relationship was found between the mRNA gradient of Slit1 or Slit2 and the orientation or turning of axons at the optic chiasm. These approaches now provide an important suite of methods for spatial analysis of axon tracts and molecular gradients in axon guidance.

▼ The objective of this investigation is to explore the use of hand gestures to control semi-autonomous vehicles, such as quadcopters, using realistic, physics based simulations. This involves identifying natural gestures to control basic functions of a vehicle, such as maneuvering and onboard equipment operation, and building simulations using the Unity game engine to investigate preferred use of those gestures. In addition to creating a realistic operating experience, human factors associated with limitations on physical hand motion and information management are also considered in the simulation development process. Testing with external participants using a recreational quadcopter simulation built in Unity was conducted to assess the suitability of the simulation and preferences between a joystick approach and the gesture-based approach. Initial feedback indicated that the simulation represented the actual vehicle performance well and that the joystick is preferred over the gesture-based approach. Improvements in the gesture-based control are documented as additional features in the simulation, such as basic maneuver training and additional vehicle positioning information, are added to assist the user to better learn the gesture-based interface and implementation of active control concepts to interpret and apply vehicle forces and torques. Tests were also conducted with an actual ground vehicle to investigate if knowledge and skill from the simulated environment transfers to a real-life scenario. To assess this, an immersive virtual reality (VR) simulation was built in Unity as a training environment to learn how to control a remote control car using gestures. This was then followed by a control of the actual ground vehicle. Observations and participant feedback indicated that range of hand movement and hand positions transferred well to the actual demonstration. This illustrated that the VR simulation environment provides a suitable learning experience, and an environment from which to assess human performance; thus, also validating the observations from earlier tests. Overall results indicate that the gesture-based approach holds promise given the emergence of new technology, but additional work needs to be pursued. This includes algorithms to process gesture data to provide more stable and precise vehicle commands and training environments to familiarize users with this new interface concept.

The aim of the present thesis is to explore the development of metacognition and computational thinking skills in Educational Robotics activities. Initially, the thesis introduces a didactic model which sets rules and conditions for creating favorable and efficient learning conditions in EP activities. The model is called CPGC +, after Collaboration, Problem, Game, and Competition, while "+" stands for supplementary teachers’ supportive interventions which aim to promote students' skills such as computational thinking, metacognitive and problem-solving skills. The dissertation then presents research results exploring techniques for guiding and supporting students to develop metacognition and computational thinking skills. In particular, it focuses on the role of guidance (strong or minimal) and on the modality of the response to the prompting questions (written, selection or discussion) as well as on the role of the students' age and gender. The positive results of the research suggest that, in the framework of the CPGC+ model and with the appropriate support and guidance techniques, Educational Robotics can be a dynamic learning tool that supports the development of students' skills, irrespective of their age and gender. In addition, incorporating prompts for written answers or for choosing the right answer, positively affects the development of their skills.

▼ In this research, the artificial immune system (AIS) paradigm is used for the development of a conceptual framework for autonomous flight when vehicle position and velocity are not available from direct sources such as the global navigation satellite systems or external landmarks and systems. The AIS is expected to provide corrections of velocity and position estimations that are only based on the outputs of onboard inertial measurement units (IMU). The AIS comprises sets of artificial memory cells that simulate the function of memory T- and B-cells in the biological immune system of vertebrates. The innate immune system uses information about invading antigens and needed antibodies. This information is encoded and sorted by T- and B-cells. The immune system has an adaptive component that can accelerate and intensify the immune response upon subsequent infection with the same antigen. The artificial memory cells attempt to mimic these characteristics for estimation error compensation and are constructed under normal conditions when all sensor systems function accurately, including those providing vehicle position and velocity information. The artificial memory cells consist of two main components: a collection of instantaneous measurements of relevant vehicle features representing the antigen and a set of instantaneous estimation errors or correction features, representing the antibodies. The antigen characterizes the dynamics of the system and is assumed to be correlated with the required corrections of position and velocity estimation or antibodies. When the navigation source is unavailable, the currently measured vehicle features from the onboard sensors are matched against the AIS antigens and the corresponding corrections are extracted and used to adjust the position and velocity estimation algorithm and provide the corrected estimation as actual measurement feedback to the vehicle’s control system. The proposed framework is implemented and tested through simulation in two versions: with corrections applied to the output or the input of the estimation scheme. For both approaches, the vehicle feature or antigen sets include increments of body axes components of acceleration and angular rate. The correction feature or antibody sets include vehicle position and velocity and vehicle acceleration adjustments, respectively. The impact on the performance of the proposed methodology produced by essential elements such as path generation method, matching algorithm, feature set, and the IMU grade was investigated. The findings demonstrated that in all cases, the proposed methodology could significantly reduce the accumulation of dead reckoning errors and can become a viable solution in situations where direct accurate measurements and other sources of information are not available. The functionality of the proposed methodology and its promising outcomes were successfully illustrated using the West Virginia University unmanned aerial system simulation environment.
