The Super-Resolution Vision System is a DARPA-sponsored project designed to create an imaging system that can “see” more sharply through optical turbulence. The system has integrated several image processing techniques into a modular package. To test the system, measurements of optical targets at ranges up to 2 km were collected at White Sands Missile Range, NM, between 13 and 15 November, 2012. This report documents the atmospheric characterization performed in support of that test to measure winds and turbulence strength present. Weather conditions during much of the test period were dry and clear, except during the afternoon of November 15. Turbulence strength (C2n) reached 2 × 10?13 m?2/3 during much of the daylight hours (0900 to 1500), providing a stressing environment for much of the testing period. Meteorological data were collected from 0630 through 1630 local time each day of the test. RM Young 81000 sonic anemometers were located at 0-, 800-, and 1800-m target points at 1.5-m elevation to provide point estimates of C2 n. Sonic anemometer data were also collected at a 0-km tower at several levels, providing a vertical turbulence profile. Turbulence data were also collected optically using scintillometers over 800- and 1800-m paths.

A new automatic approach that uses approximate deterministic solutions for providing the starting fission source for Monte Carlo eigenvalue calculations was evaluated in this analysis. By accelerating the Monte Carlo source convergence and decreasing the number of cycles that has to be skipped before the tallies’ estimation, this approach was found to increase the efficiency of the overall simulation, even with the inclusion of the extra computational time required by the deterministic calculation.

An uncommon architecture of a direct-coupled transmit/receive FMCW radar transceiver was investigated and implemented. The architecture uses a single dual polarization antenna to transmit and receive circularly polarized waves and implements a form of on-chip circulator by directing energy between common- and differential-modes on a symmetric waveguide structure.

At the most practical level, this thesis examines how to parallelize a language for laying out visualizations. By specifying important subsets of layout languages with a restricted form of constraints over trees, we find we can abstract the problem to automatically parallelizing systems of constraints. Our solution combines language design, program synthesis, and highperformance algorithms. We introduce innovatations in each of these areas in order to build our end-to-end system.This thesis introduces techniques for parallel computing over trees and applies them to generating layout engines.

This thesis investigates performance analysis for nonlinear systems, which consist of both known and unknown dynamics and may only be defined locally. We apply combinations of integral quadratic constraints (IQCs), developed by Megretski and Rantzer, and sum-of-squares(SOS) techniques for the analysis.

In this dissertation, we first discuss several formulations for Sparse PCA, as well as the algorithms for solving the formulations and a few greedy methods. We then develop a block coordinate ascent algorithm for solving DSPCA with better dependence on problem size. We show that our algorithm converges much faster than the existing first-order algorithm in practice and demonstrate that our code can handle huge real data sets. We also demonstrate that Sparse PCA does bring more interpretability and hence gives rise to new interesting findings in various real data sets.

This research aims at designing a non-invasive, low-cost, and portable imaging device for cancer screening. Conceptualization, architectural and system-level design, and finally implementation of the system called TUSI, Time-Domain Ultra-Wideband Synthetic Imager, are addressed. Using an array of closely controlled radiating silicon chips, acting as transceivers in microwave /mm-wave frequencies, this device transmits short “beam-steered” pulses and picks up reflections from tissue abnormalities (e.g. cancerous tissue). By processing the data from multiple transceivers, a larger aperture is synthesized. In essence, this imager probes the “electrical” properties of the tissue.

A stand alone, mobile photovoltaic power system along with a cable deployment system was designed and constructed to take part in the Desert Research And Technology Studies (RATS) lunar surface human interaction evaluation program at Cinder Lake, Arizona. The power system consisted of a photovoltaic array/battery system. It is capable of providing 1 kW of electrical power. The system outputs were 48 V DC, 110 V AC, and 220 V AC. A cable reel with 200 m of power cable was used to provide power from the trailer to a remote location. The cable reel was installed on a small trailer. The reel was powered to provide low to no tension deployment of the cable. The cable was connected to the 220 V AC output of the power system trailer. The power was then converted back to 110 V AC on the cable deployment trailer for use at the remote site. The Scout lunar rover demonstration vehicle was used to tow the cable trailer and deploy the power cable. This deployment was performed under a number of operational scenarios, manned operation, remote operation and tele-robotically. Once deployed, the cable was used to provide power, from the power system trailer, to run various operational tasks at the remote location.

A legged crawler's unsteady dynamics are explored with an emphasis on how these affect optical flow estimation, which mediates navigation. The optical flow algorithm's gains are further tuned using policy gradient reinforcement learning so as to improve motion estimation for specific unsteady regimes. This approach is demonstrated in an obstacle avoidance scenario.
