Autonomous Scene Understanding, Motion Planning, and Task Execution for Geometrically Adaptive Robotized Construction Work
(2019)
The construction industry suffers from such problems as high cost, poor quality, prolonged duration, and substandard safety. Robots have the potential to help alleviate such problems by becoming construction co-workers, ...
Optical Quartz Crystal Microbalance (OQCM) for Dual-Mode Analysis
(2018)
Label-free biosensors allow for real-time measurements of the target molecule, providing valuable kinetic data about the unperturbed biological system. Yet, they generally rely on a single transduction mechanism that ...
Computational Studies of Turbulent Skin-Friction Drag Reduction with Super-Hydrophobic Surfaces and Riblets
(2017)
Skin-friction Drag Reduction (DR) with SuperHydrophobic (SH) surfaces and riblets was investigated using Direct Numerical Simulation (DNS) to study the scaling and mechanism of DR, and the pressure loads on SH surfaces in ...
New Methods for Terahertz and Ultrafast Infrared Spectroscopy of Biological Materials and Graphene Buffer Layer
(2019)
The development of advanced optical spectroscopy has always been a frontier in optics and material science. This dissertation develops several new methods for terahertz (THz) and infrared spectroscopy and presents their ...
Probing Heat Transport and Energy Conversion at the Atomic and Single Molecule Scale
(2018)
The study of heat transport and energy conversion constitutes an important subject in modern physics and engineering research. The widely-applied Fourier’s and Planck’s laws have proven to be very useful to describe heat ...
Electron Acceleration and Radiation Generation from Relativistic Laser-Plasma Interactions and Statistical Methods at High Repetition-Rate
(2021)
This dissertation explores the interaction between high-intensity lasers and plasmas to accelerate electrons and produce radiation via experimental and computational efforts. The laser pulses used in this dissertation have ...
Efficient Algorithms for Light Transmission, Focusing and Scattering Matrix Retrieval in Highly Diffusive 3D Random Media
(2018)
Wavefront shaping provides an increasingly appealing avenue for imaging and other applications that require controlling electromagnetic waves passing through complex and disordered media. Indeed, these techniques allow ...
Spatial Nonlocality and Its Effects on the Scattering Characteristics of Wave-Bearing Media
(2022)
Reciprocity is the principle in the study of wave propagation that states that given a source and a receiver in a linear domain, switching their locations will not affect the received signal. Systems that break reciprocity ...
Surface Dimer Engineering and Properties of GaAs(N)(Bi) Alloys
(2018)
Due to the significant bandgap narrowing induced by dilute fractions of N and Bi in III-V semiconductors, emerging dilute nitride-bismide semiconductor alloys are of significant interest for long-wavelength applications ...
Quantum Light Scattering in Disordered and Structured Media
(2021)
Understanding the complex interactions of the quantum light with different media provides valuable insights into potential applications in quantum tomography, microscopy, circuit and network design, and imaging. This thesis ...
