26 Zhdanov, Michael S.3-D magnetic inversion with data compression and image focusingWe develop a method of 3-D magnetic anomaly inversion based on traditional Tikhonov regularization theory. We use a minimum support stabilizing functional to generate a sharp, focused inverse image. An iterative inversion process is constructed in the space of weighted model parameters that acce...2002-01-01
27 Bhanu, Bir3-D model building for computer visionThis paper presents a Computer-Aided Geometric Design (CAGD) based approach for building 3-D models which can be used for the recognition of 3-D objects for industrial machine vision applications. The objects are designed using the Alpha_1 CAGD system developed at the University of Utah. A new metho...CAGD; 3-D models; Machine vision1985
28 Ailion, David Charles31P NMR spin-lattice relaxation: structural glass dynamics in Rb1-x(ND4)xD2PO4We performed 3 1P NMR measurements of the temperature-dependent spin-lattice relaxation time in several mixed single crystals of Rbi_x(ND4 ) xD2P04 [DRADP] having different ammonium concentration x (x =0.22, 0.44, 0.78) as well as in three pure single crystals (ND4)D2P04 [DADP], (NH4)H2P04 [ADP], an...NMR; Spin-lattice; Relaxation; Crystals; Glass; Spin-glass1993
29 Ailion, David Charles; Blinc, Robert35Cl spin-lattice relaxation in incommensurate bis(4-chlorophenyl)sulfoneThe 35C1 nuclear-quadrupole-resonance (NQR) spin-lattice relaxation rate in incommensurate bis(4- chlorophenyl)sulfone (BCPS) is determined by Raman processes below 60 K and by direct one-phonon processes above 60 K. The variation of the 35C1 spin-lattice relaxation rate over the incommensurate NQR...35Cl; Incommensurate bis(4-chlorophenyl)sulfone; Raman processes; NQR; Incommensurate systems1995-01
30 Miller, Jan D.; Lin, Chen-Luh3D analysis of particulates in mineral processing systems by cone beam X-ray microtomographyIn general, x-ray computed tomographic (CT) techniques are able to provide 3D images of the internal structure of opaque materials in a nondestructive manner. The unique cone beam geometry allows acquisition of all 2D projections with only one rotation of the sample thus providing for fast data acqu...X-ray microtomography; Liberation; Heap leaching; Exposure analysis; Coal washability2003
31 Zhdanov, Michael3D inversion of airborne electromagnetic dataTime-domain airborne surveys gather hundreds of thousands of multichannel, multicomponent samples. The volume of data and other complications have made 1D inversions and transforms the only viable method to interpret these data, in spite of their limitations. We have developed a practical methodolog...2012-01-01
32 Gooch, Amy A.; Gooch, Bruce; Willemsen, Peter; Kniss, Joe; Riesenfeld, Richard F.; Shirley, Peter S.3D Line textures and the visualization of confidence in ArchitectureThis work introduces a technique for interactive walkthroughs of non-photorealistically rendered (NPR) scenes using 3D line primitives to define architectural features of the model, as well as indicate textural qualities. Line primitives are not typically used in this manner in favor of texture ma...Presentation graphics; Interactive walkthroughs2007
33 Gerig, Guido3D of brain shape and volume after cranial vault remodeling surgery for craniosynostosis correction in infantsThe skull of young children is made up of bony plates that enable growth. Craniosynostosis is a birth defect that causes one or more sutures on an infant's skull to close prematurely. Corrective surgery focuses on cranial and orbital rim shaping to return the skull to a more normal shape. Functional...2013-01-01
34 Furse, Cynthia M.3D ray-tracing for intra-vehicle environmentsIn order to develop a wireless communication system that could be used for all types of aircraft sensor networks, the severe multipath channel found inside aircrafts must be well defined. This multipath channel is much more complex than usual outdoor/indoor channels and thus far, research has been l...2009
35 Gerig, Guido3D tensor normalization for improved accuracy in DTI tensor registration methodsThis paper presents a method for normalization of diffusion tensor images (DTI) to a xed DTI template, a pre-processing step to improve the performance of full tensor based registration methods. The proposed method maps the individual tensors of the subject image in to the template space based on ma...2012-01-01
36 Morse, Michael DavidThe 3d?Ni(?F)3d10Cu???*? manifold of excited electronic states of NiCuDiatomic NiCu has been supersonically cooled in a molecular beam and investigated by resonant two-photon ionization spectroscopy. A total of nine band systems connecting the ground 3d?Ni3??Cu??, X 2?5/2 state to the 3d?Ni(3F)3d??Cu??*?? manifold of states have been found, and bands of eight of these...1992
37 Saam, Brian3He spin exchange cells for magnetic resonance imagingWe present a protocol for the consistent fabrication of glass cells to provide hyperpolarized (HP) 3He for pulmonary magnetic resonance imaging. The method for producing HP 3He is spin-exchange optical pumping. The valved cells must hold of order 1 atm.L of gas at up to 15 atm pressure. Because char...3He; Spin exchange cells; Hyperpolarized 3He; Pulmonary magnetic resonance imaging; Spin-exchange optical pumping; SEOP; Glass cells2002
38 Gerig, Guido4D active cut: an interactive tool for pathological anatomy modeling4D pathological anatomy modeling is key to understanding complex pathological brain images. It is a challenging problem due to the difficulties in detecting multiple appearing and disappearing lesions across time points and estimating dynamic changes and deformations between them. We propose a novel...2014-01-01
