  • Stimulus Familiarity Determines Recognition Strategy for Novel 3-D Objects 

    Unknown author (1989-07-01)
    We describe a psychophysical investigation of the effects of object complexity and familiarity on the variation of recognition time and recognition accuracy over different views of novel 3D objects. Our findings indicate ...

  • Stimulus Simplification and Object Representation: A Modeling Study 

    Unknown author (2002-03-15)
    Tsunoda et al. (2001) recently studied the nature of object representation in monkey inferotemporal cortex using a combination of optical imaging and extracellular recordings. In particular, they examined IT neuron ...

  • Stochastic Combinatorial Optimization with Risk 

    Unknown author (2008-09-13)
    We consider general combinatorial optimization problems that can be formulated as minimizing the weight of a feasible solution wT x over an arbitrary feasible set. For these problems we describe a broad class of corresponding ...

  • Stochastic cycle selection in active flow networks 

    Woodhouse, Francis Gordon; Forrow, Aden; Fawcett, Joanna B; Dunkel, Jörn (National Academy of Sciences of the USAProceedings of the National Academy of Sciences, 2016)
    Active biological flow networks pervade nature and span a wide range of scales, from arterial blood vessels and bronchial mucus transport in humans to bacterial flow through porous media or plasmodial shuttle streaming in ...

  • Stochastic Digital Circuits for Probabilistic Inference 

    Unknown author (2008-11-24)
    We introduce combinational stochastic logic, an abstraction that generalizes deterministic digital circuit design (based on Boolean logic gates) to the probabilistic setting. We show how this logic can be combined with ...

  • Stochastic hub and spoke networks 

    Hult, Edward Eric (University of CambridgeJudge Business School, 2011-10-11)
    Transportation systems such as mail, freight, passenger and even telecommunication systems most often employ a hub and spoke network structure since correctly designed they give a strong balance between high service quality ...

  • Stochastic Modelling Of A Chemotactic Microswimmer 

    Yahaya, Ibrahim (2011-11-23)
    Key to Escherichia coli (E-coli) bacteria survival is its ability to direct its movement to greener pasture and flee harmful environment - also known as chemotaxis. This thesis focuses on the modelling of E-coli chemotaxis ...

    Key to Escherichia coli (E-coli) bacteria survival is its ability to direct its movement to greener pasture and flee harmful environment - also known as chemotaxis. This thesis focuses on the modelling of E-coli chemotaxis ...

  • Stochastic Primal-Dual Hybrid Gradient Algorithm with Arbitrary Sampling and Imaging Applications 

    Chambolle, Antonin; Ehrhardt, Matthias Joachim; Richtárik, Peter; Schönlieb, Carola-Bibiane
    We propose a stochastic extension of the primal-dual hybrid gradient algorithm studied by Chambolle and Pock in 2011 to solve saddle point problems that are separable in the dual variable. The analysis is carried out for ...

  • A Stored Picture Hacking Facility 

    Unknown author (MIT Artificial Intelligence Laboratory, 1972-06)
    A short description of LISP functions that have been written for use with the stored picture facility. These functions allow one to display an image of a stored scene on the 340 scope, and produce graphs and histograms of ...

  • Story experience in a virtual San storytelling environment : a cultural heritage application for children and young adults 

    Ladeira, Ilda (University of Cape TownFaculty of ScienceDepartment of Computer Science, 2005)
    This dissertation explores virtual storytelling for conveying cultural stories effectively. We set out to investigate: (1) the strengths and/or weaknesses of VR as a storytelling medium; (2) the use of a culturally familiar ...

  • Story Understanding: the Beginning of a Consensus 

    Unknown author (MIT Artificial Intelligence Laboratory, 1978-06)
    This paper is written for an Area Examination on the three papers: "A Framed PAINTING: The Representation of a Common Sense Knowledge Fragment" by Eugene Charniak, "Reporter: An Intelligent Noticer" by Steve Rosenberg, and ...

  • Strategies to Implement Parallel Discrete Event System Specification Algorithms 

    Adekunle, Onaopepo Husamat (AUST, 2014-12-15)
    Discrete Event System Specification (DEVS) formalism is a Modeling and Simulation (M&S) framework that provides a means of specifying systems. It separates a model from its simulator. The former describes the structure and ...

  • Stratified shear flow: experiments in an inclined duct 

    Meyer, Colin R; Linden, Paul Frederick (Journal of Fluid Mechanics, 2014-07-22)
    We present results of experiments on stratified shear flow in an inclined duct. The duct connects two reservoirs of fluid with different densities, and contains a counterflow with a dense layer flowing beneath a less-dense layer ...


  • Strength and Fracture of Earth-Based and Natural Fiber-Reinforced Composites 

    Kabiru, Mustapha (2010-12-15)
    This study examined the mechanical properties of earth-based materials that are relevant to the future development of affordable housing. Earthcrete structures were produced by mixing various proportions of laterites, clay ...

  • Stresslets Induced by Active Swimmers 

    Lauga, Eric Jean-Marie; Michelin, Sébastien (American Physical SocietyPhysical Review Letters, 2016-09-30)
    Active particles disturb the fluid around them as force dipoles, or stresslets, which govern their collective dynamics. Unlike swimming speeds, the stresslets of active particles are rarely determined due to the lack of a ...

  • Strictly continuous extension of functionals with linear growth to the space BV 

    Rindler, Filip; Shaw, Giles (Oxford University PressThe Quarterly Journal of Mathematics, 2015-06-24)
    In this paper, we prove that the integral functional F[u]: BV(Ω;ℝ^m) → ℝ defined by F[u] := ∫_Ω f(x,u(x),∇u(x))dx + ∫_Ω ∫_1^0 f^∞ (x, u^θ (x), (d D^s u)/(d |D^s u|) (x) is continuous over BV(Ω;ℝ^m), with respect to ...
