• #### Inference by Reparameterization using Neural Population Codes ﻿

(2015-12-04)
Behavioral experiments on humans and animals suggest that the brain performs probabilistic inference to interpret its environment. Here we present a general-purpose, biologically plausible implementation of approximate ...

(1973)
• #### Information theory of transmit diversity and space-time code design ﻿

(2000)
We restate the achievable information rates for multiple transmit multiple receive antenna systems in fast fading channels. Then we consider non-ergodic channel, where we evaluate asymptotic expression for the outage ...
• #### Integral manifold based control design of an electromechanical system ﻿

(1997)
The control problem of an electromechanical system becomes more complex when the flexibility and friction are taken into account in the system model. To approach this problem, an electromechanical system is studied in this ...
• #### Interfacial charge transfer in nanoscale polymer transistors ﻿

(2009)
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 ...
• #### Intersymbol interference equalization by universal likelihood ﻿

(1997)
Codelength based inference is used to decode binary symbols distorted by an inter-symbol interference (ISI) channel with additive noise. The transmitted signals are antipodal waveforms constructed from $\pm$1 valued signature ...
• #### Inverse kinematics and dynamic control methods for robotic systems ﻿

(1995)
This dissertation presents new algorithms for inverse kinematic computations of robotic manipulators and for the control of multiple cooperating manipulator systems. The results presented in this thesis can be classified ...
• #### Inverse model for the extraction of biological parameters from ovarian tissue fluorescence spectra and multivariate classifiers for tissue diagnosis ﻿

(2007)
We present an inverse model to decompose bulk fluorescence spectra and extract tissue biological parameters. By deconvolving the effects of absorption and scattering from measured spectra, we are able to extract the intrinsic ...
• #### Inverse problems in image processing ﻿

(2004)
Inverse problems involve estimating parameters or data from inadequate observations; the observations are often noisy and contain incomplete information about the target parameter or data due to physical limitations of the ...
• #### Investigating self-assembly of functionalized nanotubes and peptides by tunneling microscopy ﻿

(2006)
Scanning tunneling microscopy (STM) is an ideal tool for probing the chemistry and physics of these types of nanostructures. Building upon on our previous carbon nanotube research, we have investigated thiol and thiophene ...
• #### Investigation of graphitic nanostructures and nanomachines ﻿

(2010)
Carbon allotropes such as nanotubes, graphene, and buckyball all preserve the same lattice structure. However, their electronic properties are very different depending on their dimensionality. These nanostructures can be ...
• #### INVESTIGATION OF LITHIUM - NIOBIUM TRIOXIDE THIN FILMS IN MIS STRUCTURE (FERROELECTRIC) ﻿

(1986)
Thin film LiNbO(,3) was deposited on silicon substrates by using r.f. sputtering techniques under different conditions. A set of films was deposited with different substrate temperatures and with different gas mixtures ...

(1972)
• #### Investigations in improving image visualization and quality in positron emission tomography/computed tomography (PET/CT) imaging ﻿

(2010)
Positron Emission Tomography/Computed Tomography (PET/CT) is a widely used imaging modality for managing patients with cancer. The combination of PET and CT can provide both functional and anatomic information of disease ...
• #### IO-lite: A copy-free UNIX I/O system ﻿

(1997)
Memory copy speed is known to be a significant barrier to high-speed communication. We perform an analysis of the requirements for a copy-free buffer system, develop an implementation-independent applications programming ...
• #### Ionization of Rydberg atoms by half-cycle pulses: Effect of pulse shape and rise time ﻿

(1998)
The ionization of potassium np Rydberg atoms with $n\sim388$ by pulsed unidirectional electric fields, termed half-cycle pulses (HCPs), with various well-characterized shapes (rectangular, triangular, and sawtooth) and ...
• #### Issues in myoelectric teleoperation of complex artificial hands ﻿

(1995)
This dissertation introduces a novel method of teleoperation of complex anthropomorphic robotic hands: converting the myoelectric signal generated by an operator's muscles during movement into robot commands replicating ...
• #### Issues related to data mining with self organizing maps ﻿

(2004)
This thesis demonstrates that the clustering by Kohonen's Self-Organizing Map algorithm (KSOM) can be significantly improved by magnification control. As a second contribution, the thesis proposes a fully automated technique ...
• #### Iterative design of l(p) digital filters ﻿

(2008)
The design of digital filters is a fundamental process in the context of digital signal processing. Being essential building blocks, digital filters are used in diverse areas ranging from medical imaging or audio and video ...
