Micro-photoluminescence spectroscopy of excitons in individual single-walled carbon nanotubes
Single-walled carbon nanotubes (SWNTs) are fascinating materials to study one-dimensional photophysics. Their optical properties are strongly affected by strong Coulomb interactions and are determined by "excitons" which ...
Spectrum sharing techniques for next generation cellular networks
Spectrum sharing is an opportunistic strategy to improve the efficient usage of the frequency spectrum. Much of the research to quantify these gains are under the premise that the spectrum is being used inefficiently. Our ...
A High Throughput Configurable SDR Detector for Multi-user MIMO Wireless Systems
Spatial division multiplexing (SDM) in MIMO technology significantly increases the spectral efficiency, and hence capacity, of a wireless communication system: it is a core component of the next generation wireless ...
High Throughput VLSI Architecture for Soft-Output MIMO Detection Based on A Greedy Graph Algorithm
Maximum-likelihood (ML) decoding is a very computational- intensive task for multiple-input multiple-output (MIMO) wireless channel detection. This paper presents a new graph based algorithm to achieve near ML performance ...
A Theoretical Analysis of Joint Manifolds
The emergence of low-cost sensor architectures for diverse modalities has made it possible to deploy sensor arrays that capture a single event from a large number of vantage points and using multiple modalities. In many ...
Workload shaping for QoS and power efficiency of storage systems
The growing popularity of hosted storage services and shared storage infrastructure in data centers is driving the recent interest in resource management and QoS in storage systems. The bursty nature of storage workloads ...
The characteristics of nanoscale sunscreen particles
This thesis describes the characterization and photochemical behavior of metal oxide nanopigments derived from commercial sunscreens. We investigate their size, morphology, elemental composition, and crystal structure using ...
Fast, Exact Synthesis of Gaussian and nonGaussian Long-Range-Dependent Processes
1/f noise and statistically self-similar random processes such as fractional Brownian motion (fBm) and fractional Gaussian noise (fGn) are fundamental models for a host of real-world phenomena, from network traffic to ...
