• #### Fourier transform infrared spectroscopy of 6.1-Angstrom semiconductor quantum wells ﻿

(2002)
The 6.1-Angstrom (A) family of III-V semiconductors---InAs, GaSb, and AlSb and their alloys and heterostructures---has unique properties that may find application in next generation multi-functional semiconductor devices. ...
• #### Full-Duplex Infrastructure Nodes: Achieving Long Range with Half-duplex Mobiles ﻿

(2012-09-05)
One of the primary sources of inefficiency in today's wireless networks is the half-duplex constraint - the assumption that nodes cannot transmit and receive simultaneously in the same band. The reason for this constraint ...
• #### Full-duplex Wireless with Large Antenna Arrays ﻿

(2015-12-03)
To meet the growing demand for wireless data, base stations with very large antenna arrays are being deployed in order to serve multiple users simultaneously. Concurrently, there is growing interest in full-duplex operation. ...
• #### Full-duplex Wireless: Design, Implementation and Characterization ﻿

(2012)
One of the fundamental assumptions made in the design of wireless networks is that the wireless devices have to be half-duplex, i.e., they cannot simultaneously transmit and receive in the same frequency band. The key ...
• #### Fully Integrated CMOS-Compatible Photodetector with Intrinsic Gain and Red-Green-Blue Color Selectivity ﻿

(2014-04-21)
Currently, image sensors are hybrid devices, combining semiconductor photodiodes with off-chip color filters of different materials to convert wavelength-selected light into useful photocurrent. Here we demonstrate a fully ...
• #### Fundamental limits in spike sorting ﻿

(2007)
Spike sorting refers to the detection and classification of electric potentials (spikes) from multi-neuron recordings. It is a difficult but essential pre-processing step before neural data can be analyzed for information ...

• #### Gamma radiation from excited states of light nuclei (fluorine-19 + alpha, oxygen-18 + proton, oxygen-16 + helium-3, and fluorine-19 + deuteron ﻿

(1959)
Abstract Not Available.

(1986)
• #### General-purpose architectures for media processing and database workloads ﻿

(2000)
Workloads on general-purpose computing systems have changed dramatically over the past few years, with greater emphasis on emerging compute-intensive applications such as media processing and databases. However, until ...
• #### GENERALIZED REPLACEMENT IN ITERATIVE RESTORATION ALGORITHMS ﻿

(1983)
A new formulation of an iterative restoration algorithm is presented in this dissertation for the solution of noisy, non-linear restoration problems. The constraints and distortions are assumed to be known and are modeled ...
• #### Genomic Detection Using Sparsity-inspired Tools ﻿

(2011)
Genome-based detection methods provide the most conclusive means for establishing the presence of microbial species. A prime example of their use is in the detection of bacterial species, many of which are naturally vital ...

(1971)
• #### Gold nanoshells: Optical properties and femtosecond electron dynamics ﻿

(1998)
The chemistry, optical properties, and femtosecond electron dynamics of gold nanoshells are described. The gold nanoshells consist of Au-coated Au$\sb2$S nanoparticles prepared via aqueous phase chemistry using HAuCl$\sb4$ ...
• #### Golden-Eye: A server-side location-sensing system for wireless LANs ﻿

(2004)
Determining the location of a wireless client is a key problem for location-aware systems and for security applications. Many recent studies have used Bayesian methods to determine location from wireless LAN signals, but ...
• #### GPU Accelerated Reconfigurable Detector and Precoder for Massive MIMO SDR Systems ﻿

(2015-12-02)
We present a reconfigurable GPU-based unified detector and precoder for massive MIMO software-defined radio systems. To enable high throughput, we implement the linear minimum mean square error detector/precoder and further ...
• #### Graphene Photonic Devices for Terahertz and Mid-Infrared ﻿

(2013-11-08)
Graphene and other strictly two-dimensional materials are the rising stars on the horizon of material science, condensed matter physics and engineering. The richness of optical and electronic properties of graphene attract ...

(1978)
• #### Hierarchical robot path planning using a distributed blackboard ﻿

(1990)
Hierarchical path planning techniques for Intelligent Autonomous Mobile Robots (IAMRs) attempt to subdivide the overall task of path planning into several layers. This subdivision is made more difficult by the physical ...
