(2020-03-26)In the past couple of decades, wireless communication has undergone rapid development. The current fourth generation and upcoming fifth generation wireless technologies promise us an ultra-fast data rate. However, a lot ... -
Phased array impedance tuning, secure transmission, and nonlinear spatial intermodulation suppression for next-generation radar and communications systems.
(2020-03-30)Simultaneously transmitting radar and communications signals from the same multi-beam phased array system, using spatial diversity, allows multiple functions to use the same frequency and can alleviate spectral congestion. ... -
Faster circuit optimization techniques for full-band and notched waveforms to enable next-generation radar.
(2020-04-14)As the wireless spectrum becomes increasingly congested, more efficient sharing of the spectrum is desperately needed. In order to coexist, next-generation radars will have to adapt their spectral use in real-time. Two ... -
A model of clocked electric field inputs for molecular quantum-dot cellular automata.
(2019-11-08)Quantum-dot cellular automata (QCA) is a low-power, high-speed, beyond- CMOS approach to general-purpose computing [1]. Elementary devices called “cells” are implemented using mixed-valence molecules with redox centers ... -
An electromagnetic sensor and method for extraction of transient vapor fraction in dynamic systems.
(2019-11-06)The capture of transient steam quality provides valuable insight into the operational conditions needed for process control and design of saturated steam systems. Acquisition of accurate fluid phase or composition before ... -
Application of coordinated control strategies to tubular solid oxide fuel cell models.
(2019-07-17)Solid oxide fuel cell (SOFC) power plants have been demonstrated to produce power efficiently in theory and in practice. However, popular control methods have not accounted for controlling the SOFC and the connecting power ... -
Fabrication and demonstration of a microfluidic device toward a microfluidic-based microinjection for Cx. pipiens embryo.
(2019-07-17)According to the World Health Organization (WHO), more than 390 million people each year have reported being affected by mosquito borne diseases. In order to prevent epidemics of fatal diseases, altering mosquitoes through ... -
Investigation of a trapezoidal microchannel for hydrodynamic detachment of cells or biomolecules.
(2019-05-29)Fluid-based non-specific adsorption (NSA) methods and cell adhesion studies both use hydrodynamic forces to detach biomolecules or cells. To address the limitations in current microfluidic detachment assays and NSA removal ... -

High-density intraoperative brain monitoring during cardiac surgery.
(2019-04-10)Functional near-infrared spectroscopy (fNIRS) is a prominent technique that allows assessment of functional brain activity by measuring hemodynamic responses. Most existing functional brain imaging methods are only capable ... -
An explicit electron-vibron model for olfactory inelastic electron transfer spectroscopy.
(2019-04-01)The vibrational theory of olfaction was posited to explain subtle effects in the sense of smell inexplicable by models in which molecular structure alone determines an odorant’s smell. Amazingly, behavioral and neurophysiological ... -
Diamagnetic and plasmonic properties of graphene.
(2018-12-12)Graphene is a two-dimensional (2D) material, and it has many applications in electronics and photonics due to its unique properties. We study diamagnetism of graphene and demonstrate applications of graphene in sensing, ... -
Ambiguity function magnitude inversion and applications of morphological dilation in POCS.
(2018-11-15)This dissertation examines morphological dilation for applications in Projection onto Convex Sets (POCS) as well as the inversion of ambiguity function magnitude. In general, POCS solvers implement Least-Squares (LS) ... -
Evaluating approaches to detecting ice accretion in and around turbofan jet engines.
(2018-07-19)The accumulation of ice crystals in the compressor stages of a jet engine causes power loss events during flight that could potentially become catastrophic. The electromagnetic properties of ice clouds make them nearly ... -
Robust and efficient methods for proton computed tomography.
(2018-07-23)Proton computed tomography (pCT) is a recent promising imaging modality with the goal of generating accurate 3D maps of relative stopping power (RSP) with respect to water. Since the early developments of this imaging ... -
Circuit optimization and frequency agility for cognitive radar.
(2018-04-27)Due to the increased demand on the spectrum, radars are in increased stress to participate in dynamic spectrum allocation. Therefore, the next generation radar will be an adaptable cognitive radar. This type of radar will ... -
Semi-supervised learning for electrocardiography signal classification.
(2018-04-24)An electrocardiogram (ECG) is a cardiology test that provides information about the structure and function of the heart. The size of the ECG data collected from patients can be very large, and the data analysis is tedious. ...
