  • Wang, Carter; Osorio Pizano, Carolina (Elsevier, 2012-11)
    Traditional queueing network models assume infinite queue capacities due to the complexity of capturing interactions between finite capacity queues. Accounting for this correlation can help explain how congestion propagates ...
  • Li, Zi Rui; Liu, Gui Rong; Cheng, Yuan; Han, Jongyoon; Chen, Yu Zong; Wang, Jian-Sheng; Hadjiconstantinou, Nicolas (American Physical Society, 2009-06)
    We present a theoretical model describing Ogston (pore size comparable to or larger than the characteristic molecular dimension) sieving of rigid isotropic and anisotropic biomolecules in nanofluidic molecular filter arrays ...
  • Chen, Ying; Schuh, Christopher A. (American Physical Society, 2009-03)
    We present an easy-to-implement technique for determining the effective properties of composite materials with periodic microstructures, as well as the field distributions in them. Our method is based on the transformation ...
  • Stohl, A.; Seibert, P.; Arduini, J.; Eckhardt, S.; Fraser, P.; Greally, B. R.; Lunder, C.; Maione, M.; Muhle, J.; O'Doherty, S.; Prinn, Ronald G.; Reimann, S.; Saito, T.; Schmidbauer, N.; Simmonds, P. G.; Vollmer, M. K.; Weiss, R. F.; Yokouchi, Y. (European Geophysical Society, 2009-03)
    A new analytical inversion method has been developed to determine the regional and global emissions of long-lived atmospheric trace gases. It exploits in situ measurement data from three global networks and builds on ...
  • Gogineni, Usha; del Alamo, Jesus A.; Valdes-Garcia, Alberto (Institute of Electrical and Electronics Engineers (IEEE), 2011-07)
    This paper presents a first order model for RF power of deeply scaled CMOS. The model highlights the role of device on-resistance in determining the maximum RF power. We show excellent agreement between the model and the ...
  • Tow, Emily W.; Lienhard, John H. (ASME International, 2013-07)
    Bubble column dehumidifiers are a compact, inexpensive alternative to conventional fin-tube dehumidifiers for humidification-dehumidification (HDH) desalination, a technology that has promising applications in small-scale ...
  • Emig, Thorsten; Graham, Noah; Faghfoor Maghrebi, Mohammad; Rahi, Sahand Jamal; Jaffe, Robert L.; Kardar, Mehran (National Academy of Sciences, 2011-04)
    Casimir forces between conductors at the submicron scale are paramount to the design and operation of microelectromechanical devices. However, these forces depend nontrivially on geometry, and existing analytical formulae ...
  • Orr, F. M. Jr; Seto, Carolyn Jennifer (Springer Netherlands, 2009-06)
    This paper presents the first instance of a double contact discontinuity in analytical solutions for multicomponent, two-phase flow in porous media. We use a three-component system with constant equilibrium ratios and fixed ...
  • Iwasa, Yukikazu; Bascunan, Juan; Bobrov, Emanuel Saul; Ahn, Min Cheol; Hahn, Seung-Yong (Institute of Electrical and Electronics Engineers, 2009-07)
    This paper addresses adverse effects of dimensional uncertainties of an HTS insert assembled with double-pancake coils on spatial field homogeneity. Each DP coil was wound with Bi2223 tapes having dimensional tolerances ...
  • Carter, Joshua Adam; Yee, Jennifer C.; Eastman, Jason; Gaudi, B. Scott; Winn, Joshua Nathan (Cambridge University Press, 2009-02)
    The light curve of an exoplanetary transit can be used to estimate the planetary radius and other parameters of interest. Because accurate parameter estimation is a non-analytic and computationally intensive problem, it ...
  • Hirano, Teruyuki; Suto, Yasushi; Taruya, Atsushi; Narita, Norio; Sato, Bun'ei; Johnson, John Asher; Winn (IOP Publishing, 2010-01)
    We obtain analytical expressions for the velocity anomaly due to the Rossiter- McLaughlin effect, for the case when the anomalous radial velocity is obtained by cross-correlation with a stellar template spectrum. In the ...
  • Greytak, Matthew B.; Hover, Franz S. (Institute of Electrical and Electronics Engineers, 2009-07)
    Path planning algorithms that incorporate risk and uncertainty need to be able to predict the evolution of path-following error statistics for each candidate plan. We present an analytic method to predict the evolving error ...
  • Cerfon, A. J.; Freidberg, Jeffrey P.; Parra Fabian, Ignacio Esteban; Antaya, T. A. (American Physical Society, 2013-02)
    Using a two-dimensional fluid description, we investigate the nonlinear radial-longitudinal dynamics of intense beams in isochronous cyclotrons in the nonrelativistic limit. With a multiscale analysis separating the time ...
  • Balasubramanian, Koushik; McGreevy, John (American Physical Society, 2009-11)
    A Lifshitz point is described by a quantum field theory with anisotropic scale invariance (but not Galilean invariance). In 8, gravity duals were conjectured for such theories. We construct analytically a black hole that ...
  • Falcao-Filho, Edilson L.; Gkortsas, Vasileios-Marios; Kaertner, Franz X.; Gordon, Ariel (Optical Society of America, 2009-06)
    Closed form expressions for the high harmonic generation (HHG) conversion efficiency are obtained for the plateau and cutoff regions. The presented formulas eliminate most of the computational complexity related to HHG ...
  • Pelletier, Jon D.; Perron, J. Taylor (American Geophysical Union (AGU), 2012-05)
    The geomorphic literature contains many analytic solutions for the topographic evolution of gently sloping soil-mantled hillslopes responding to base level changes. Most of these solutions are limited to vertical base level ...
  • Pires, R.; Repp, M.; Ulmanis, J.; Kuhnle, E. D.; Tiecke, T. G.; Greene, Chris H.; Ruzic, Brandon P.; Bohn, John L.; Tiemann, E.; Weidemuller, M. (American Physical Society, 2014-07)
    We provide a comprehensive comparison of a coupled channel calculation, the asymptotic bound-state model (ABM), and the multichannel quantum defect theory (MQDT). Quantitative results for [superscript 6]Li-[superscript ...
  • Johnson, Kristine Dianne; Simchi-Levi, David; Sun, Peng (Institute for Operations Research and the Management Sciences (INFORMS), 2014-06)
    Scrip systems provide a nonmonetary trade economy for exchange of resources. We model a scrip system as a stochastic game and study system design issues on selection rules to match potential trade partners over time. We ...
  • Chakrabarti, Ayan; Zickler, Todd; Freeman, William T. (Institute of Electrical and Electronics Engineers (IEEE), 2010-08)
    Blur is caused by a pixel receiving light from multiple scene points, and in many cases, such as object motion, the induced blur varies spatially across the image plane. However, the seemingly straight-forward task of ...
  • Custo, Anna; Boas, David A.; Tsuzuki, Daisuke; Dan, Ippeita; Mesquita, Rickson; Fischl, Bruce; Grimson, W. Eric L.; Wells, William M. (Elsevier, 2009-07)
    We describe a neuroimaging protocol that utilizes an anatomical atlas of the human head to guide diffuse optical tomography of human brain activation. The protocol is demonstrated by imaging the hemodynamic response to ...
