Photothermal energy conversion by plasmonic nanoparticles
Photothermal energy conversion is important when designing optically active devices based on plasmonic nanoparticles. Many early applications of these nanoparticles, like photothermal tumor ablation, drug delivery, and ...
Supporting vehicular mobility in urban multi-hop wireless networks
Deployments of city-wide multi-hop 802.11 networks introduce challenges for maintaining client performance at vehicular speeds. In this thesis, we experimentally demonstrate that current network interfaces employ policies ...
Interfacial charge transfer in nanoscale polymer transistors
Interfacial charge transfer plays an essential role in establishing the relative alignment of the metal Fermi level and the energy bands of organic semiconductors. While the details remain elusive in many systems, this ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
