• #### 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 ...
• #### Inversion Formula for Continuous Multifractals ﻿

(1997-01-20)
In a previous paper the authors introduced the inverse measure <i>Âµ</i><sup>â  </sup> of a probability measure <i>Âµ</i> on [0,1]. It was argued that the respective multifractal spectra are linked by the 'inversion formula' ...
• #### Investigating irregularly patterned deep brain stimulation signal design using biophysical models ﻿

(2015-06)
Parkinson's disease (PD) is a neurodegenerative disorder which follows from cell loss of dopaminergic neurons in the substantia nigra pars compacta (SNc), a nucleus in the basal ganglia (BG). Deep brain stimulation (DBS) ...
• #### Investigating Multiple Candidate Genes and Nutrients in the Folate Metabolism Pathway to Detect Genetic and Nutritional Risk Factors for Lung Cancer ﻿

(2013)
Purpose: Folate metabolism, with its importance to DNA repair, provides a promising region for genetic investigation of lung cancer risk. This project investigates genes (MTHFR, MTR, MTRR, CBS, SHMT1, TYMS), folate metabolism ...
• #### 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 ...
• #### Investigation of Reliability of Hydraulic Robots for Hazardous Environments Using Analytic Redundancy ﻿

(1999-01-01)
The Rosie mobile worksystem is a robot that is on the cutting edge of hazardous environment robotics. It is a heavy-duty hydraulic robot designed for nuclear reactor decontamination and dismantlement. The robot consists ...

• #### 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 ...
• #### Isolating the Performance Impacts of Network Interface Cards through Microbenchmarks ﻿

(2004-06-01)
This paper studies the impact of network interface cards (NICs) on network server performance, testing six different Gigabit Ethernet NICs. Even with all other hardware and software configurations unchanged, a network ...
