  • Ross, Adam Michael; Stein, David B.; Hastings, Daniel E. (American Institute of Aeronautics and Astronautics, 2013-11-19)
    Multi-Attribute Tradespace Exploration for Survivability is a system design and analysis methodology that incorporates survivability considerations into the tradespace exploration process (i.e., a solution-generating and ...
  • Xu, Jun; Fang, Nicholas Xuanlai; Cui, Yanxia; Fung, Kin Hung; He, Sailing (Optical Society of America, 2012-07)
    We demonstrate a multiband plasmonic absorber based on transverse phase resonances. We show that the modification of conventional metallic surfaces of T-shape grooves can cause mode splitting of the plasmonic waveguide ...
  • Shah, Devavrat; Niesen, Urs; Gupta, Piyush (Institute of Electrical and Electronics Engineers, 2009-06)
    We study the problem of determining the multicast capacity region of a wireless network of n nodes randomly located in an extended area and communicating with each other over Gaussian fading channels. We obtain an explicit ...
  • Tse, David N. C.; Soriaga, Joseph B.; Hou, Jilei; Smee, John E.; Padovani, Roberto; Jing, Sheng (Hindawi Publishing Corporation, 2008-04)
    Abstract We study the potential benefits of base-station (BS) cooperation for downlink transmission in multicell networks. Based on a modified Wyner-type model with users clustered at the cell-edges, we analyze the ...
  • Secord, Thomas W.; Mazumdar, Anirban; Asada, Harry (Institute of Electrical and Electronics Engineers, 2010-07)
    Variable stiffness actuation and energy harvesting have been important yet separate challenges in robotics. Both functions are needed, however, for mobile robots on extended missions when actuators and generators must be ...
  • Clifford, Gari D.; Sameni, Reza; Jutten, Christian; Shamsollahi, Mohammad B. (Hindawi Publishing Corporation, 2007-01)
    A three-dimensional dynamic model of the electrical activity of the heart is presented. The model is based on the single dipole model of the heart and is later related to the body surface potentials through a linear model ...
  • Potter, Andrew Cole; Lee, Patrick A. (American Physical Society, 2010-11)
    The ends of one-dimensional p+ip superconductors have long been predicted to possess localized Majorana fermion modes [A. Kitaev, arXiv:cond-mat/0010440]. We show that Majorana end states are robust beyond the strict 1D ...
  • Gamarnik, David; Stolyar, Alexander L. (Springer-Verlag, 2012-04)
    We consider a heterogeneous queueing system consisting of one large pool of O(r) identical servers, where r→∞ is the scaling parameter. The arriving customers belong to one of several classes which determines the service ...
  • Trigg, Jason A.; Gutwin, Karl; Keating, Amy E.; Berger, Bonnie (Public Library of Science, 2011-08)
    The alpha-helical coiled coil can adopt a variety of topologies, among the most common of which are parallel and antiparallel dimers and trimers. We present Multicoil2, an algorithm that predicts both the location and ...
  • Paster, Eli Travis; Ruddy, Bryan P.; Pillai, Priam V.; Hunter, Ian (SPIE, 2011-03)
    Conducting polymer materials can be employed as actuation elements, length sensors, force sensors, energy storage devices, and electrical components. Combining the various functionalities of conducting polymers to create ...
  • Bilgic, Berkin; Adalsteinsson, Elfar; Goyal, Vivek K. (Wiley Blackwell, 2011-06)
    Clinical imaging with structural MRI routinely relies on multiple acquisitions of the same region of interest under several different contrast preparations. This work presents a reconstruction algorithm based on Bayesian ...
  • Leonardi, Christopher Ross; Holmes, David W.; Williams, John R.; Tilke, Peter G. (Society for Modeling & Simulation International, 2011-04)
    This paper presents a numerical framework that enables scalable, parallel execution of engineering simulations on multi-core, shared memory architectures. Distribution of the simulations is done by selective hash-tabling ...
  • Finchelstein, D. F.; Sze, Vivienne; Chandrakasan, Anantha P. (Institute of Electrical and Electronics Engineers, 2009-10)
    Performance requirements for video decoding will continue to rise in the future due to the adoption of higher resolutions and faster frame rates. Multicore processing is an effective way to handle the resulting increase ...
  • Bond, Robert A.; Kim, Hahn G. (Institute of Electrical and Electronics Engineers, 2009-10)
    Multicore architectures require parallel computation and explicit management of the memory hierarchy, both of which add programming complexity and are unfamiliar to most programmers. While MPI and OpenMP still have a place ...
  • Williams, John R.; Holmes, David W.; Tilke, Peter G. (Queen Mary, University of London, 2010-08)
    This paper discusses the implementation of particle based numerical methods on multi-core machines. In contrast to cluster computing, where memory is distributed across machines, multi-core machine can share memory across ...
  • Malakis, A.; Berker, A. Nihat; Hadjiagapiou, I.A.; Fytas, N.G.; Papakonstantinou, T. (American Physical Society, 2010-04)
    The effects of bond randomness on the phase diagram and critical behavior of the square lattice ferromagnetic Blume-Capel model are discussed. The system is studied in both the pure and disordered versions by the same ...
  • Han, Qing; Bradshaw, Elizabeth M.; Nilsson, Björn; Hafler, David A.; Love, J. Christopher; Nilsson, Bjorn (Royal Society of Chemistry, 2010-04)
    The large diversity of cells that comprise the human immune system requires methods that can resolve the individual contributions of specific subsets to an immunological response. Microengraving is process that uses a ...
  • Ranger, Manon; Celeste Johnston, C.; Rennick, Janet E.; Limperopoulos, Catherine; Heldt, Thomas; du Plessis, Adre J. (Lippincott Williams & Wilkins, 2013-07)
    Objectives: Inferring the pain level of a critically ill infant is complex. The ability to accurately extract the appropriate pain cues from observations is often jeopardized when heavy sedation and muscular blocking agents ...
  • McBee, Megan E.; Su, Dan; Pang, Yan Ling Joy; Gu, Chen; Prestwich, Erin; Dedon, Peter C.; Chionh, Yok Hian; Ho, Chia-Hua; Pruksakorn, Dumnoensun; Indrakanti, Ramesh Babu; Ng, Chee Sheng; Hia, Fabian; Dong, Hongping; Shi, Pei-Yong; Preiser, Peter Rainer; Alonso, Sylvie (Oxford University Press, 2013-08)
    A renewed interest in non-coding RNA (ncRNA) has led to the discovery of novel RNA species and post-transcriptional ribonucleoside modifications, and an emerging appreciation for the role of ncRNA in RNA epigenetics. ...
  • Kewlani, Gaurav; Iagnemma, Karl (Institute of Electrical and Electronics Engineers, 2009-12)
    The ability of mobile robots to quickly and accurately analyze their dynamics is critical to their safety and efficient operation. In field conditions, significant uncertainty is associated with terrain and/or vehicle ...
