    • A (HELIUM-3)-(HELIUM-4) DILUTION REFRIGERATOR 

      PEDERSON, DONALD OTIS (1971)
    • A 2-D simulation study on CO2ᅠsoluble surfactant for foam enhanced oil recovery 

      Zeng, Yongchao; Farajzadeh, Rouhi; Biswal, Sibani L.; Hirasaki, George J. (2019)
      This paper probes the transport of CO2ᅠsoluble surfactant for foaming in porous media. We numerically investigate the effect of surfactant partitioning between the aqueous phase and the gaseous phase on foam transport for subsurface applications when the surfactant is injected in the CO2ᅠphase. A 2-D reservoir simulation is developed to quantify the ...
    • A 200 MeV proton spin polarimeter 

      Rice, James Allen (1983)
      The design, construction, and calibration of a 2 MeV proton spin polarimeter are described. This polarimeter monitors the beam at the transfer point between the linear accelerator and the Alternating Gradient Synchrotron at Brookhaven National Laboratory. The polarimeter determines the beam polarization to an accuracy of 1% in less than ten minutes ...
    • A 2D optical lattice for creating a 1-dimensional Fermi gas 

      Paprotta, Tobias (2009)
      Ultracold atomic gases can be prepared in laboratory environments with unrivaled control and purity. In one and a half decades the field has evolved from the first Bose condensates in dilute alkali gases to multiple species mixtures and degenerate Fermi systems. Combining quantum degenerate fermions and optical lattices enables the simulation of ...
    • A 3.0 meter liquid mirror telescope 

      Mulrooney, Mark (2000)
      We constructed a 3.0 meter diameter f/1.5 Liquid Mirror Telescope (LMT) between 1990 and 1994 at the NASA Johnson Space Center, Houston, Texas. We have subsequently operated it since 1995 at the NASA Orbital Debris Observatory (NODO), Cloudcroft, NM. Employing an inexpensive rotating container of mercury as its primary parabolic mirror, the NASA LMT ...
    • A 3D microfluidic tumor model to study immune cell infiltration into solid tumors 

      Vu, Timothy Q (2017-08-07)
      The tumor microenvironment consists of other cells besides cancer cells, including immune cells like T-cells, natural killer cells, and macrophages. The roles of these infiltrated cells, however, are diverse and can be both pro- or anti-tumorigenic. The effects of infiltrated natural killer cells are poorly characterized and highly misunderstood. To ...
    • A 3D printable perfused hydrogel vascular model to assay ultrasound-induced permeability 

      Royse, Madison K.; Means, A. Kristen; Calderon, Gisele A.; Kinstlinger, Ian S.; He, Yufang; (2022)
      The development of an in vitro model to study vascular permeability is vital for clinical applications such as the targeted delivery of therapeutics. This work demonstrates the use of a perfusion-based 3D printable hydrogel vascular model as an assessment for endothelial permeability and its barrier function. Aside from providing a platform that more ...
    • 'A Almshouse Ting Dat': Developments in Poor Relief and Child Welfare in Jamaica during the Interwar Years 

      Roper, Shani (2013-07-24)
      This dissertation examines the development of poor relief and child welfare policy in Jamaica during the interwar years. It establishes the paradigms for accessing relief and how this influenced broader discussions of poverty, class and citizenship in society. As such it shows how these concerns about poverty, in the public sphere, influenced state ...
    • A Ball and Beam Module for a Haptic Paddle Education Platform 

      Rose, Chad G.; Bucki, Nathan; O’Malley, Marcia K. (2017)
      Single degree of freedom force-feedback mechatronic devices, often called haptic paddles, are used in university curriculum as well as massive open online courses (MOOCs). While devices differ based on the goals of a given course, broadly speaking they provide hands-on learning for students studying mechatronics and dynamics. We introduce the third ...
    • A Bayesian approach for capturing daily heterogeneity in intra-daily durations time series 

      Brownlees, Christian T.; Vannucci, Marina (2013)
      Intra-daily financial durations time series typically exhibit evidence of long range dependence. This has motivated the introduction of models able to reproduce this stylized fact, like the Fractionally Integrated Autoregressive Conditional Duration Model. In this work we introduce a novel specification able to capture long range dependence. We propose ...
    • A Bayesian hierarchical model for detecting associations between haplotypes and disease using unphased SNPs 

      Fox, Garrett Reed (2008)
      This thesis addresses using haplotypes to detect disease predisposing chromosomal regions based on a Bayesian hierarchical model for case-control data. By utilizing the Stochastic Search Variable Selection (SSVS) procedure of George and McCulloch (1997), the number of parameters is riot constrained by the sample size, as are the frequentist methods. ...
    • A Bayesian Integrative Model for Genetical Genomics with Spatially Informed Variable Selection 

      Cassese, Alberto; Guindani, Michele; Vannucci, Marina (2014)
      We consider a Bayesian hierarchical model for the integration of gene expression levels with comparative genomic hybridization (CGH) array measurements collected on the same subjects. The approach defines a measurement error model that relates the gene expression levels to latent copy number states. In turn, the latent states are related to the ...
    • A Bayesian Multivariate Functional Dynamic Linear Model 

      Kowal, Daniel R.; Matteson, David S.; Ruppert, David (2017)
      We present a Bayesian approach for modeling multivariate, dependent functional data. To account for the three dominant structural features in the data—functional, time dependent, and multivariate components—we extend hierarchical dynamic linear models for multivariate time series to the functional data setting. We also develop Bayesian spline theory ...
    • A Bayesian Nonparametric Spiked Process Prior for Dynamic Model Selection 

      Cassese, Alberto; Zhu, Weixuan; Guindani, Michele; Vannucci, Marina (2019)
      In many applications, investigators monitor processes that vary in space and time, with the goal of identifying temporally persistent and spatially localized departures from a baseline or “normal” behavior. In this manuscript, we consider the monitoring of pneumonia and influenza (P&I) mortality, to detect influenza outbreaks in the continental United ...
    • A behavioral approach to positive interpolation 

      Mayo, Andrew (2005)
      We study interpolation by positive functions from a behavioural point of view. In particular, by considering the notion of mirror image data, the interpolation problem with passivity constraint is transformed into an unconstrained behavioural modeling one. It will be shown that the generating system for this problem has to be unitary with respect to ...
    • A binary encoded strip scintillation hodoscope for charged particle detection 

      Hoftiezer, John H. (1977)
      A position-sensitive scintillation hodoscope with reduced photomultiplier use has been built. The device is an attempt to develop an economical, fast counter with good timing characteristics, good spatial resolution, and high efficiency. Isolated strips of plastic organic scintillator form a single layer (per dimension) detecting surface, while ...
