26 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
27 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

29 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.

37 Mathews, V. JohnA baseband residual vector quantization algorithm for voiceband data signalsAbstract-In this paper, we present a new approach to the digitization and compression of a class of voiceband modem signals. Our approach, which we call baseband residual vector quantization (BRVQ), relies heavily upon the simple structure present in a modem signal. After the signal is converted to...1989
38 Sekercioglu, CaganA birders quide to TurkeyAs I write, it is early December and the woods outside my window lay dusted with snow like a holiday card by Currier and Ives. A minute ago, I looked up and caught a glimpse of an adult Cooper's Hawk dashing swiftly through the trees. It swooped up, landed on a branch, then briefly shook its tail an...2006-01-01
39 Mathews, V. John; Schlegel, ChristianA blind adaptive projection receiver for CDMA systemsAbstract - This paper presents a blind and adaptive CDMA receiver that does not require knowledge of the spreading codes associated with users other than the ones of interest.

50 Jones, David T.A comparative study of certain goblet cellsThe origin of the primordial droplets has been rightly given the primary place in the study of secretion. Bowen has limited the term secretion to the actual synthesis of these droplets from cytoplasmic materials, which limitation we shall accept. The secondary problems in this field concern chieflly...1937-06
