A System for the Detection of Adversarial Attacks in Computer Vision via Performance Metrics
… or attacks committed by an adversary to hijack a system, are prevalent in the deep learning tasks of computer vision and are one of the greatest threats to these models' safe and accurate use. These attacks force the trained model to misclassify an image, using pixel-level changes undetectable to …

A noise-gated PLL for clock recovery in a free-space laser communication system
In this thesis, I developed a phase-locked loop system for data clock recovery in a free-space laser communication application. The clock recovery unit is designed to operate at extremely low optical received power, tolerate a fading channel, and also account for Doppler effects. I explored the …

Inventory planning for low demand items in online retailing
… backordering costs in determining the optimal system inventory level and allocation of inventory to warehouses. For the case of Poisson demand and constant replenishment lead time, we develop methods to approximate the key system performance metrics like transshipment, backorders and average …

Analysis of airline schedule padding on U.S. domestic routes
… for them. Using flight data from FAA Aviation System Performance Metrics, we analyze the scheduled and actual flight times on 2359 directional non-stop domestic routes during 2009. The time of each flight is decomposed to delay at gate, taxi-out time, airborne time and taxi-in time. Then, the …

Crosstalk mitigation of high-speed interconnects using modal signaling
… integrity impairments, which in turn limit the system performance and signaling rate. The focus of this research is to explore the application of modal decomposition of coupled transmission lines to crosstalk mitigation of high-speed interconnects, in particular far-end crosstalk (FEXT), which …
