Guided-mode-resonance-coupled plasmonic-active SiO₂ nanotubes for surface enhanced Raman spectroscopy

Creator:: Xu, Xiaobin, Hasan, Dihan, Wang, Lei, Chakravarty, Swapnajit, Chen, Ray T., Fan, D. L., and Wang, Alan X.
Abstract:: We demonstrate a surface enhanced Raman scattering (SERS) substrate by integrating plasmonic-active SiO₂ nanotubes into Si₃N₄ gratings. First, the dielectric grating that is working under guided mode resonance (GMR) provides enhanced electric field for localized surface plasmon polaritons on the surface of metallic nanoparticles. Second, we use SiO₂ nanotubes with...

Wave Energy Converter Modeling in the Frequency Domain : A Design Guide

Creator:: Bosma, Bret, Zhang, Zhe, Brekken, Ted K. A., Özkan-Haller, H. Tuba, McNatt, Cameron, and Yim, Solomon C.
Abstract:: Wave energy converter research continues to advance and new developers are continuing to emerge, leading to the need for a general modeling methodology. This work attempts to outline the design methodology necessary to perform frequency domain analysis on a generic wave energy converter. A two-body point absorber representing a generic...

Adversarial Policy Switching with Application to RTS Games

Creator:: King, Brian, Fern, Alan, and Hostetler, Jesse
Abstract:: Complex games such as RTS games are naturally formalized as Markov games. Given a Markov game, it is often possible to hand-code or learn a set of policies that capture the diversity of possible strategies. It is also often possible to hand-code or learn an abstract simulator of the game...

On surrogate supervision multi-view learning

Creator:: Jin, Gaole
Abstract:: Data can be represented in multiple views. Traditional multi-view learning methods (i.e., co-training, multi-task learning) focus on improving learning performance using information from the auxiliary view, although information from the target view is sufficient for learning task. However, this work addresses a semi-supervised case of multi-view learning, the surrogate supervision...

Time and statistical information utilization in high efficiency sub-micron CMOS successive approximation analog to digital converters

Creator:: Guerber, Jon
Abstract:: In an industrial and consumer electronic marketplace that is increasingly demanding greater real-world interactivity in portable and distributed devices, analog to digital converter efficiency and performance is being carefully examined. The successive approximation (SAR) analog to digital converter (ADC) architecture has become popular for its high efficiency at mid-speed and...

A probabilistic framework and algorithms for modeling and analyzing multi-instance data

Creator:: Behmardi, Behrouz
Abstract:: Multi-instance data, in which each object (e.g., a document) is a collection of instances (e.g., word), are widespread in machine learning, signal processing, computer vision, bioinformatic, music, and social sciences. Existing probabilistic models, e.g., latent Dirichlet allocation (LDA), probabilistic latent semantic indexing (pLSI), and discrete component analysis (DCA), have been...

Maximum flow in planar digraphs

Creator:: Harutyunyan, Anna
Abstract:: Worst-case analysis is often meaningless in practice. Some problems never reach the anticipated worst-case complexity. Other solutions get bogged down with impractical constants during implementation, despite having favorable asymptotic running times. In this thesis, we investigate these contrasts in the context of finding maximum flows in planar digraphs. We suggest...

Hybrid computational voxelization using the graphics pipeline

Creator:: Rauwendaal, Randall
Abstract:: This thesis presents an efficient computational voxelization approach that utilizes the graphics pipeline. Our approach is hybrid in that it performs a precise gap-free computational voxelization, employs fixed-function components of the GPU, and utilizes the stages of the graphics pipeline to improve parallelism. This approach makes use of the latest...

Performance and optimization of pulsed UWB localization with large number of sources

Creator:: Kwon, Changho
Abstract:: Pulsed ultra-wideband (UWB) radio uses extremely short pulses to transmit information. Such pulses provide very fine timing information, which has led to technological advances in high-precision localization. This thesis focuses on techniques and experiments of Time-Difference-of-Arrival (TDOA) localization of a large number of simultaneous sources. First, common localization techniques such...

Efficient detection and scheduling for MIMO-OFDM systems

Creator:: Liu, Wei
Abstract:: Multiple-input multiple-output (MIMO) antennas can be exploited to provide high data rate using a limited bandwidth through multiplexing gain. MIMO combined with orthogonal frequency division multiplexing (OFDM) could potentially provide high data rate and high spectral efficiency in frequency-selective fading channels. MIMO-OFDM technology has been widely employed in modern communication...
