• #### Statistical characterization of sensors for sensor fusion ﻿

(1996)
It is standard practice in advanced telerobotic systems to use a detailed model of the operating environment to plan tasks and drive simulations. How well these systems operate is highly dependent upon the accuracy of this ...

(1975)
• #### Structure of Knowledge Representation and Reasoning ﻿

(1988)
This thesis deals with one important aspect of Artificial Intelligence, knowledge representation and reasoning. Problems like knowledge representation hypothesis, production systems, and the proceduralist and declarativist ...
• #### Studies in system representation and control ﻿

(1995)
Representation of an abstract system by a mathematical object such as a matrix or a differential equation is important because much of the analysis is done via representations. For discrete-time input-output systems, ...
• #### Studies of an injection controlled rare gas halide excimer laser ﻿

(1988)
Characteristics of an injection-controlled electron-beam pumped XeF(C $\to$ A) excimer laser have been investigated with emphasis on efficient wideband tuning and scaling issues. Using a quasi-cw dye laser as an injection ...

(1972)
• #### Studies on capacity and performance of digital transmission over copper loops ﻿

(1995)
Digital transmission over copper loops is studied. Models are found of main sources of interference, including near-end crosstalk (NEXT), far-end crosstalk (FEXT), impulse noise (IN) and intersymbol interference (ISI). ...

• #### Sub-wavelength Metallic Ring Apertures for Communications, Sensing and Nonlinear Optics ﻿

(2013-11-06)
In this thesis, we demonstrate sub-wavelength ring aperture arrays in a metal film which can be used for communications, material sensing, and nonlinear optics. We show in simulation and experiment extraordinary optical ...
• #### Subnet discovery in passive internally sensed network tomography ﻿

(2007)
Passive internally-sensed network tomography is the study of network characteristics and behavior based on observations of network traffic on a select subset of links inside the network. In this research, we identify the ...
• #### Subradiant, superradiant and Fano resonances in dimer and ring/disk nanocavities ﻿

(2010)
Subradiant and superradiant plasmon modes in ring/disk nanocavities and dialers are investigated theoretically and experimentally. The subradiance is obtained through an overall reduction of the total dipole moment of the ...
• #### Supporting vehicular mobility in urban multi-hop wireless networks ﻿

(2009)
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 ...
• #### Surface enhanced Raman scattering with metal nanoshells ﻿

(2004)
A systematic investigation of surface enhanced Raman scattering (SERS) was performed using metal nanoshells as the substrate. Nanoshells are a dielectric sphere coated with a thin metal shell, which have a well understood, ...
• #### Suspended Si Ring Resonator for Mid-IR Application ﻿

(2013-11-22)
Suspended ring resonators formed by both single-mode waveguide (SMW) and multi-mode waveguide (MMW) are designed, fabricated and characterized near 3.4 μm by thermal tuning and near 4.5 μm and 5.2 μm by tunable quantum ...
• #### SWIR Imaging and Echelle Spectroscopy via Compressive Sensing ﻿

(2012)
A new sampling theory, called compressive sensing (CS), has recently emerged and its fundamental idea can be distilled as: it is possible to obtain near complete recovery of a signal/image from a small set of mixed ...

(1972)
• #### Symbol timing synchronization for OFDM-based WLAN systems ﻿

(2008)
In this work, we address the problem of symbol timing synchronization for Orthogonal Frequency Division Multiplexing (OFDM) WLAN systems. OFDM systems are known to be sensitive to synchronization errors and improving the ...
• #### SYNTHESIS OF OPTIMAL CONTROL SYSTEMS WITH STABLE FEEDBACK ﻿

(1987)
In this thesis, the question of optimal control system design when constrained to using a stable controller is addressed. The performance index that is minimized is H$\sp\infty$-norm of the sensitivity of the closed-loop ...
