• #### A variational study of the electrical impedance tomography problem ﻿

(2002)
This research is focused on the numerical solution of the inverse conductivity problem, widely known as electrical impedance tomography (EIT). The EIT problem is concerned with imaging electrical properties, such as ...
• #### A vision-based fuzzy logic and neural network approach to the control of hyper-redundant robot manipulators ﻿

(1994)
Hyper-redundant robot manipulators possess a very large degree of kinematic redundancy and are capable of motion similar to that of snakes and elephant trunks. Because of the computational burden required to calculate the ...
• #### A waste water treatment plant as a contemporary public space ﻿

(2007)
The piazza is failing as a typology of public space in Florence, Italy due to sprawl, tourism, and the profuse use of the car. However, the city of Florence keeps building new piazzas to act as a public space inside the ...
• #### A wavelet-based approach to three-dimensional confocal microscopy image reconstruction ﻿

(2004)
An algorithm based on the Haar wavelet basis and implementing an expectation maximization-maximum penalized likelihood estimator in 3-D is shown to provide dramatic improvement over traditional stopped-EM algorithms in ...
• #### A wavelet-based numerical scheme for stochastic mechanics ﻿

(2000)
Uncertainty is an inherent part of many physical systems. This is often ignored to simplify mathematical models thereby leading to a deterministic treatment of the system. Incorporation of the uncertainty into the model, ...

(1968)

(1972)
• #### A zonally and annually averaged study of potential early Martian atmospheres ﻿

(1993)
Observations of the surface of Mars suggest a high probability of surface water activity in that planet's past. Consequently, many studies of Mars' early atmosphere have attempted to estimate the carbon dioxide level by ...

(1979)
• #### A. Isothermal adsorption studies in the system soap-water. B. The adsorption of water by silica and alumina at high temperatures ﻿

(1951)
Systematic adsorption studies have not been made on soap samples of known crystalline form. Recent investigations in soap chemistry have been directed to the practical determination of the soap-water phase diagram and to ...

(1978)
• #### Ab initio methods for protein structure prediction ﻿

(2010)
Recent breakthroughs in DNA and protein sequencing have unlocked many secrets of molecular biology. A complete understanding of gene function, however, requires a protein structure in addition to its sequence. Modern protein ...
• #### Ab initio theoretical study of the small fullerenes carbon(20)-carbon(36) ﻿

(1997)
Ab initio SCF Hartree-Fock calculations have been carried out on all the fullerene isomers of C$\sb{20}$ to C$\sb{36}.\ C\sb{20},\ C\sb{24},$ and C$\sb{26}$ have only one fullerene isomer each, of $C\sb{2h},\ D\sb6$ and ...
• #### Abounding Interiors ﻿

(2014-04-24)
Within the history of the graphic plan, cell-based and wall-based plans comprise a dialectic of definition and openness. A new type of architectural project whose formal legibility operates predominantly in the plan has ...
• #### Abraham Lincoln's Northwestern Approach to the Secession Crisis ﻿

(2013-09-16)
While the migration of Abraham Lincoln’s family to the Northwest has often been documented as a significant event of his youth, historians have neglected the powerful repercussions this family decision had on Lincoln’s ...
• #### Absence to presence: The life history of Sylvia [Bataille] Lacan (France) ﻿

(1995)
Sylvia (Bataille) Lacan (1908-1993) was a french film actress who was married to the philosopher Georges Bataille and to the psychoanalyst Jacques Lacan. Despite this fact, she is virtually absent from the critical accounts ...
• #### Absent mothers, absent fathers: Aspects of German Fascism as seen through the contemporary camera (Germany, Helma Sanders-Brahms, Agnieszka Holland, Marianne S. W. Rosenbaum, Su Friedrich) ﻿

(1993)
The personal history of individuals during the World War II and post-war period is looked at through the film texts "Deutschland, bleiche Mutter", "Europa, Europa", "Peppermint Frieden" and "The Ties That Bind". These film ...
• #### Absolute calibration of a retarding-potential Mott polarimeter ﻿

(1992)
Mott polarimeters are used in many areas of physics to determine the spin polarization of electrons in studies of processes dependent on the electron's intrinsic spin angular momentum and associated spin magnetic moment. ...
• #### Absolute differential and integral cross sections for charge transfer of state-selected keV oxygen ion with oxygen(2) ﻿

(1998)
Absolute differential and integral charge transfer cross sections have been measured for 0.5, 0.85, 1.5, 2.8, and 5.0 keV O$\sp+$ with O$\sb2$ at scattering angles between 0.01$\sp\circ$ and 3.50$\sp\circ$ in the laboratory ...
