Effects Of Uncertainty Refinement On Satellite Collision Probability, Bruce Thomas Morrison
Effects Of Uncertainty Refinement On Satellite Collision Probability, Bruce Thomas Morrison
Masters Theses
"Due to the drastic increase in orbital debris about the Earth, the likelihood for new and current mission satellites to collide with other objects grows. When a mission satellite is placed in a highly populated orbit in the vicinity of other satellites or debris, it is necessary to consider the probability of collision to assess any possible conjunctions. The computation of the collision probability is heavily dependent on the relative position and velocity of the objects during conjunction, as well as the combined covariance. There are two main types of analytic collision probability computations; the first assumes that the objects …
Object Detection, Classification, And Tracking For Autonomous Vehicle, Milan Aryal
Object Detection, Classification, And Tracking For Autonomous Vehicle, Milan Aryal
Masters Theses
The detection and tracking of objects around an autonomous vehicle is essential to operate safely. This paper presents an algorithm to detect, classify, and track objects. All objects are classified as moving or stationary as well as by type (e.g. vehicle, pedestrian, or other). The proposed approach uses state of the art deep-learning network YOLO (You Only Look Once) combined with data from a laser scanner to detect and classify the objects and estimate the position of objects around the car. The Oriented FAST and Rotated BRIEF (ORB) feature descriptor is used to match the same object from one image …
Optical Tracking System To Monitor Laparoscopic Training, William D. Rytlewski
Optical Tracking System To Monitor Laparoscopic Training, William D. Rytlewski
Masters Theses
Laparoscopic Surgery, also known as Minimally Invasive Surgery, is a surgical technique where surgeons perform surgery through small incisions in the patient’s abdomen using a camera to monitor the movements of the instruments inside the patient. In order for the surgery to be performed, the surgeon must possess a unique set of skills obtained through training using a variety of techniques. Simulators are the preferred method of training for laparoscopic surgery since they provide medical residents with real world scenarios as well as a tremendous amount of feedback on what he/she did wrong or right. However, due to the high …

Cyber-Adaptive Physical Systems For Automated Construction Progress Monitoring And Asset Tracking, Syed Hammad Rasheed
Masters Theses
Despite the benefits of building information models as a means of communication, collaboration and integration in construction projects, their use is often limited to the design and tendering/bidding stage. Potential of building information models lies in its implementation during construction, operations and maintenance phases of a facility’s lifecycle. Tight Integration of building information model and physical facility by means of computational resources is required to achieve this potential such that changes in one environment are automatically reflected in the other. This is termed a cyber-adaptive physical systems approach. This research investigates the applicability of a cyber-adaptive physical systems approach in …
