  • Shaker, Hamid Reza; How, Jonathan P. (Institute of Electrical and Electronics Engineers, 2010-07)
    Stability analysis for a class of switched nonlinear systems is addressed in this paper. Two linear matrix inequality (LMI) based sufficient conditions for asymptotic stability are proposed for switched nonlinear systems. ...
  • Cueto-Felgueroso, Luis; Juanes, Ruben (American Physical Society, 2009-03)
    The formation of preferential flow paths during infiltration of water into homogeneous, dry soil is an important phenomenon whose explanation and prediction have remained elusive under the standard theories of multiphase ...
  • Englot, Brendan J.; Hover, Franz S. (Institute of Electrical and Electronics Engineers, 2009-12)
    Our aim is to explore the fundamental stability issues of a robotic vehicle carrying out localization, mapping, and feedback control in a perturbation-filled environment. Motivated by the application of an ocean vehicle ...
  • Rajapakse, Jagath; Mundra, Piyushkumar A. (BioMed Central Ltd, 2011-11)
    Background: Biological networks are constantly subjected to random perturbations, and efficient feedback and compensatory mechanisms exist to maintain their stability. There is an increased interest in building gene ...
  • Bizzi, Emilio; Piron, Lamberto; Agostini, Michela; Turolla, Andrea; Silvoni, Stefano; Cheung, Vincent Chi-Kwan (National Academy of Sciences, 2009-11)
    Production of voluntary movements relies critically on the functional integration of several motor cortical areas, such as the primary motor cortex, and the spinal circuitries. Surprisingly, after almost 40 years of research, ...
  • Grocholski, Brent; Shim, Sang-Heon Dan; Prakapenka, V. B. (American Geophysical Union, 2010-07)
    First-principles calculations on MgSiO(subscript 3) suggested a breakdown into MgO + SiO(subscript 2) at pressure above 1000 GPa with an extremely large negative Clapeyron slope, isolating the lowermost mantles of larger ...
  • Polanco, Miguel Angel Mendez; Grinberg, Ilya; Kolpak, Alexie M.; Levchenko, Sergey V.; Pynn, Christopher; Rappe, Andrew M. (American Physical Society, 2012-06)
    Stable ferroelectric (FE) phases in nanometer-thick films would enable ultra-high density and fast FE field effect transistors (FeFETs), and the stability of ferroelectricity in ultrathin films has been under intense ...
  • Kim, Pilnam; Kim, Sung Jae; Han, Jongyoon; Suh, Kahp Y. (American Chemical Society (ACS), 2009-12)
    We demonstrate a recycled ion-flux through heterogeneous nanoporous junctions, which induce stable ion concentration polarization with an electric field. The nanoporous junctions are based on integration of ionic hydrogels ...
  • Sinha, Niraj; Melnik, R. V. N.; Anand, S.; Mahapatra, D. Roy (The International Society for Optical Engineering, 2009-08)
    In this paper, we propose a new design configuration for a carbon nanotube (CNT) array based pulsed field emission device to stabilize the field emission current. In the new design, we consider a pointed height distribution ...
  • Peters, Steven Conrad; Bobrow, James E.; Iagnemma, Karl (Institute of Electrical and Electronics Engineers, 2010-07)
    An analogy between the dynamics of a cart-pole system and vehicle rollover dynamics is used to derive a controller for tipping up and stabilizing a planar model of a passenger vehicle near rollover by controlling lateral ...
  • Wood, Levi Benjamin; Asada, Harry (Institute of Electrical and Electronics Engineers (IEEE), 2009-07)
    This work develops a provably stable broadcast feedback approach to regulating the aggregate output of a collection of stochastically behaving cellular units with pronounced hysteresis. Similar to skeletal muscle, comprised ...
  • Manchester, Ian R.; Mettin, Uwe; Iida, Fumiya; Tedrake, Russell Louis (Sage, 2011-01)
    We propose a constructive control design for stabilization of non-periodic trajectories of underactuated robots. An important example of such a system is an underactuated “dynamic walking” biped robot traversing rough or ...
  • Kubota, Yasuo; Liu, Jun; Hu, Dan; DeCoteau, William E.; Eden, Uri T.; Smith, Anne C.; Graybiel, Ann M. (American Physiological Society, 2009-10)
    The sensorimotor striatum, as part of the brain's habit circuitry, has been suggested to store fixed action values as a result of stimulus-response learning and has been contrasted with a more flexible system that conditionally ...
  • Zaheer, Saad; Rahi, Sahand Jamal (American Physical Society, 2010-02)
    We investigate a stable Casimir force configuration consisting of an object contained inside a spherical or spheroidal cavity filled with a dielectric medium. The spring constant for displacements from the center of the ...
  • Cai, T. Tony; Wang, Lie; Xu, Guangwu (Institute of Electrical and Electronics Engineers / IEEE Information Theory Society, 2010-07)
    This article considers sparse signal recovery in the presence of noise. A mutual incoherence condition which was previously used for exact recovery in the noiseless case is shown to be sufficient for stable recovery in the ...
  • Bond, Bradley N.; Daniel, Luca (Institute of Electrical and Electronics Engineers, 2009-09)
    This paper presents theoretical and practical results concerning the stability of piecewise-linear (PWL) reduced models for the purposes of analog macromodeling. Results include proofs of input-output (I/O) stability for ...
  • Kashinath, Abishek; Demkowicz, Michael J.; Misra, A. (American Physical Society, 2013-02)
    He implanted into metals precipitates into nanoscale bubbles that may later grow into voids, degrading the properties of engineering alloys. Using multiscale modeling, we show that a different class of He precipitates may ...
  • Ajoy, Ashok; Cappellaro, Paola (American Physical Society, 2012-12)
    Gyroscopes find wide applications in everyday life from navigation and inertial sensing to rotation sensors in hand-held devices and automobiles. Current devices, based on either atomic or solid-state systems, impose a ...
  • Cardinal, Jean; Demaine, Erik D.; Fiorini, Samuel; Joret, Gwenaël; Newman, Ilan; Weimann, Oren (Springer, 2009-01)
    The Stackelberg Minimum Spanning Tree Game is a two-level combinatorial pricing problem introduced at WADS’07. The game is played on a graph, whose edges are colored either red or blue, and where the red edges have a given ...
  • Feldser, David M.; Kostova, Kamena K.; Winslow, Monte Meier; Taylor, Sarah E.; Cashman, Chris; Whittaker, Charles A.; Sanchez-Rivera, Francisco J.; Resnick, Rebecca; Bronson, Roderick T.; Hemann, Michael; Jacks, Tyler E. (Nature Publishing Group, 2010-11)
    Tumorigenesis is a multistep process that results from the sequential accumulation of mutations in key oncogene and tumour suppressor pathways. Personalized cancer therapy that is based on targeting these underlying genetic ...
