Controlling Electromagnetic Surface Waves with Scalar and Tensor Impedance Surfaces.
(2013)
The propagation characteristics of electromagnetic waves on various isotropic (scalar) impedance surfaces have been studied for some time, in order to control surface waves and leaky-wave radiation. One and two dimensional ...
Designing Thermal Modulators for Portable GC x GC Systems.
(2015)
Microelectromechanical systems (MEMS) have the advantage of scale and can be manufactured in bulk. One of the active areas of MEMS research is the development of micro-scale comprehensive two-dimensional gas chromatography ...
Toward Co-Design of Autonomous Aerospace Cyber-Physical Systems.
(2014)
Modern vehicles are equipped with a complex suite of computing (cyber) and electromechanical (physical) systems. Holistic design, modeling, and optimization of such Cyber-Physical Systems (CPS) requires new techniques ...
HgCdTe Auger-Suppressed Infrared Detectors Under Non-Equilibrium Operation.
(2009)
A nearly universal goal for infrared photon detection systems is to increase their operating temperature without sacrificing performance. The limiting factor for cooling requirements is the dark current in the detector ...
Structural Characterization and Impedance Spectroscopy of Substituted, Fused-Ring Organic Semiconductors.
(2011)
Organic materials present a number of advantages over silicon that make them ideal candidates for modest performance devices like active matrix backplanes and RFID tags. The work detailed here describes both structural ...
Nonholonomic Virtual Constraints and Gait Optimization for Robust Robot Walking Control.
(2016)
Bipedal locomotion is well suited for mobile robotics because it promises to allow robots to traverse difficult terrain and work effectively in man-made environments. Despite this inherent advantage, however, no existing ...
Improving Statistical Image Reconstruction for Cardiac X-ray Computed Tomography.
(2014)
Technological advances in CT imaging pose new challenges such as increased X-ray radiation dose and complexity of image reconstruction. Statistical image reconstruction methods use realistic models that incorporate the ...
Advances in Simultaneous Localization and Mapping in Confined Underwater Environments Using Sonar and Optical Imaging.
(2016)
This thesis reports on the incorporation of surface information into a probabilistic simultaneous localization and mapping (SLAM) framework used on an autonomous underwater vehicle (AUV) designed for underwater inspection. ...
Plasma Discharges in Gas Bubbles in Liquid Water: Breakdown Mechanisms and Resultant Chemistry.
(2015)
The use of atmospheric pressure plasmas in gases and liquids for purification of liquids has been investigated by numerous researchers, and is highly attractive due to their strong potential as a disinfectant and sterilizer. ...
A Three-Dimensional Bidirectional Interface for Neural Mapping Studies
(2010)
Advances in neuro-medicine depend critically on supporting technologies, including those associated with penetrating microelectrodes. While these have developed from single-site microwires to three-dimensional micromachined ...
