  • da Costa, David Carvalho Teixeira; de Neufville, Richard (Transportation Research Board of the National Academies, 2012-11)
    This paper provides a practical procedure for designing efficient taxi pickup operations at airports. How to do this effectively is an open question. Solutions are not available, and practices vary. They reflect different ...
  • Joshi, Ajay J.; Kim, Byungsub; Stojanovic, Vladimir Marko (Institute of Electrical and Electronics Engineers, 2009-09)
    In a power and area constrained multicore system, the on-chip communication network needs to be carefully designed to maximize the system performance and programmer productivity while minimizing energy and area. In this ...
  • Rodriguez-Wong, Alejandro; Woolf, David; Hui, Pui-Chuen; Iwase, Eiji; McCauley, Alexander Patrick; Capasso, Federico; Loncar, Marko; Johnson, Steven G. (American Institute of Physics, 2011-05)
    We propose an optomechanical structure consisting of a photonic-crystal (holey) membrane suspended above a layered silicon-on-insulator substrate in which resonant bonding/antibonding optical forces created by externally ...
  • Stojanovic, Vladimir Marko; Shamim, Imran; Batten, Christopher; Joshi, Ajay J.; Kwon, Yong-Jin; Beamer, Scott; Asanovic, Krste (Institute of Electrical and Electronics Engineers, 2009-12)
    We present a vertical integration approach for designing silicon photonic networks for communication in manycore systems. Using a top-down approach we project the photonic device requirements for a 64-tile system designed ...
  • Twu, Nancy; Li, Xin; Urban, Alexander; Balasubramanian, Mahalingam; Lee, Jinhyuk; Liu, Lei; Ceder, Gerbrand (American Chemical Society (ACS), 2014-12)
    Increasing lithium content is shown to be a successful strategy for designing new cathode materials. In layered Li[subscript x]N[subscript 2–4x/3]Sb[subscript x/3O[subscript 2] (x = 1.00–1.15), lithium excess improves both ...
  • Asatekin, Ayse; Barr, Miles C.; Baxamusa, Salmaan H.; Lau, Kenneth K.S.; Tenhaeff, Wyatt; Xu, Jingjing; Gleason, Karen K. (Elsevier, 2010-04)
    Chemical Vapor Deposition (CVD) methods significantly augment the capabilities of traditional surface modification techniques for designing polymeric surfaces. In CVD polymerization, the monomer(s) are delivered to the ...
  • Marbleston, Adam Henry; Boyden, Edward Stuart; Marblestone, Adam Henry (Elsevier, 2014-09)
    Can we develop technologies to systematically map classical mechanisms throughout the brain, while retaining the flexibility to investigate new mechanisms as they are discovered? We discuss principles of scalable, flexible ...
  • Brizzolara, Stefano; Grassi, Davide; Tincani, Emilio P. (Hindawi Publishing Corporation, 2012)
    The main theoretical and numerical aspects of a design method for optimum contrar-rotating (CR) propellers for fast marine crafts are presented. We propose a reformulated version of a well-known design theory for contra-rotating ...
  • Burkhart, Justin M.; Korsunsky, Roman; Perreault, David J. (Institute of Electrical and Electronics Engineers (IEEE), 2013-04)
    This paper introduces a design methodology for a resonant boost converter topology that is suitable for operation at very high frequencies. The topology we examine features a low parts count and fast transient response, ...
  • Burkhart, Justin M.; Korsunsky, Roman; Perreault, David J. (IEEE Industry Applications Society, 2010-06)

  • Parkesh, Raman; Childs-Disney, Jessica L.; Nakamori, Masayuki; Kumar, Amit; Wang, Eric; Wang, Thomas; Hoskins, Jason; Tran, Tuan; Thornton, Charles A.; Disney, Matthew D.; Housman, David E. (American Chemical Society (ACS), 2012-02)
    Myotonic dystrophy type 1 (DM1) is a triplet repeating disorder caused by expanded CTG repeats in the 3′-untranslated region of the dystrophia myotonica protein kinase (DMPK) gene. The transcribed repeats fold into an RNA ...
  • Slocum, Alexander H.; Bosworth, William R.; Mazumdar, Anirban; Saez, Miguel A.; Culpepper, Martin Luther; Levine, Robert A. (American Society of Mechanical Engineers, 2009-06)
    This paper focuses on the design and implementation of a percutaneous catheter-based device to provide physicians with an externally controlled tool capable of manipulating and cutting specific chordae tendinae within the ...
  • Ramanujam, Rohit Sunkam; Soteriou, Vassos; Lin, Bill; Peh, Li-Shiuan (Institute of Electrical and Electronics Engineers (IEEE), 2010-07)
    Router microarchitecture plays a central role in the performance of an on-chip network (NoC). Buffers are needed in routers to house incoming flits which cannot be immediately forwarded due to contention. This buffering ...
  • Castonia, Ryan; Boussemart, Yves; Cummings, M. L. (American Institute of Aeronautics and Astronautics, 2010-04)
    This paper presents the findings from the design, development, and evaluation of a hidden semi-Markov model based operator state monitoring display. This operator state monitoring display is designed to function as a ...
  • Dorsch, Daniel S.; Winter, Amos (ASME International, 2014-08)
    The Atlantic razor clam (Ensis directus) burrows by contracting its valves, fluidizing the surrounding soil and reducing burrowing drag. Moving through a fluidized, rather than static, soil requires energy that scales ...
  • Bassett, Erik K.; Slocum, Alexander H.; Masiakos, Peter T.; Pryor, Howard I., II; Farokhzad, Omid C.; Karp, Jeffrey Michael (National Academy of Sciences, 2009-03)
    Insertion of trocars, needles, and catheters into unintended tissues or tissue compartments results in hundreds of thousands of complications annually. Current methods for blood vessel cannulation or epidural, chest tube, ...
  • Burgess, Ian B.; Zhang, Yinan; McCutcheon, Murray W.; Rodriguez, Alejandro W.; Bravo-Abad, Jorge; Johnson, Steven G.; Loncar, Marko (Optical Society of America, 2009-10)
    We propose a scheme for efficient cavity-enhanced nonlinear THz generation via difference-frequency generation (DFG) processes using a triply resonant system based on photonic crystal cavities. We show that high nonlinear ...
