  • Why Classical Finite difference Approximations fail for a singularly perturbed System of Convection-Diffusion Equations 

    Aroh, Innocent Tagbo (2016-06-07)
    We consider classical Finite Difference Scheme for a system of singularly perturbed convection-diffusion equations coupled in their reactive terms, we prove that the classical SFD scheme is not a robust technique for solving ...

  • Why Conniving is Better than Planning 

    Unknown author (1972-02-01)
    A higher level language derives its great power form the fact that it tends to impose structure on the problem solving behavior for the user. Besides providing a library of useful subroutines with a uniform calling ...

  • Why Conniving is Better than Plannng 

    Unknown author (1972-04-01)
    This paper is a critique of a computer programming language, Carl Hewitts PLANNER, a formalism designed especially to cope with the problems that Artificial Intelligence encounters. It is our contention that the ...

  • Why Do We See Three-dimensional Objects? 

    Unknown author (1992-06-01)
    When we look at certain line-drawings, we see three-dimensional objects. The question is why; why not just see two-dimensional images? We theorize that we see objects rather than images because the objects we see are, ...

  • Why Stereo Vision is Not Always About 3D Reconstruction 

    Unknown author (1993-07-01)
    It is commonly assumed that the goal of stereovision is computing explicit 3D scene reconstructions. We show that very accurate camera calibration is needed to support this, and that such accurate calibration is difficult ...

  • Wicked Problems and Gnarly Results: Reflecting on Design and Evaluation Methods for Idiosyncratic Personal Information Management Tasks 

    Unknown author (2008-02-10)
    This paper is a case study of an artifact design and evaluation process; it is a reflection on how right thinking about design methods may at times result in sub-optimal results. Our goal has been to assess our decision ...

  • Wide-Area Egomotion Estimation from Known 3D Structure 

    Unknown author (2006-01-09)
    We describe an algorithm that takes as inputs a coarse3D model of an environment, and a video sequence acquiredwithin the environment, and produces as output an estimateof the camera s 6-DOF egomotion expressed in the ...

  • Wireless Sensor Networks for Environmental Monitoring Applications 

    Odo, Christian Maduabuchi (2016-08-16)
    After many years of rigorous research and development in wireless sensor network (WSN) technology with numerous responses to innovative applications, WSNs still have some interesting unanswered questions. In this thesis ...

  • WIRElist 

    Unknown author (1969-01-01)
    This memo describes a design aid used for the automatic production of wirelists for machine or hand wiring of wire-cards.

  • Witt groups of complex varieties 

    Zibrowius, Marcus (University of CambridgeDepartment of Pure Mathematics and Mathematical StatisticsTrinity Hall, 2011-07-12)
    The thesis Witt Groups of Complex Varieties studies and compares two related cohomology theories that arise in the areas of algebraic geometry and topology: the algebraic theory of Witt groups, and real topological K-theory. ...

  • A workflow for geocoding South African addresses 

    Van Rensburg, Alexandria (University of Cape TownFaculty of ScienceDepartment of Computer Science, 2015)
    There are many industries that have long been utilizing Geographical Information Systems (GIS) for spatial analysis. In many parts of the world, it has gained less popularity because of inaccurate geocoding methods and a ...

  • Workshop Manual on Water Filtration

  • Workshop on the Design and Control of Dextrous Hands 

    Unknown author (1982-04-01)
    The Workshop for the Design and Control of Dexterous Hands was held at the MIT Artificial Intelligence Laboratory on November 5-6, 1981. Outside experts were brought together to discuss four topics: kinematics of hands, ...

  • World Wide Web Without Walls 

    Unknown author (2007-08-24)
    Today's Web is built upon a particular symbiotic relationship betweensites and users: the sites invest capital to create and market a setof features, and users gain access to the sites often in exchange fortheir data (e.g., ...

  • Worldline CPT and massless supermultiplets 

    Arvanitakis, Alexandros-Spyridon; Mezincescu, L; Townsend, Paul Kingsley (World Scientific PublishingInternational Journal of Modern Physics A, 2016-09-30)
    The action for a massless particle in 4D Minkowski space–time has a worldline-time reversing symmetry corresponding to CPT invariance of the quantum theory. The analogous symmetry of the $\mathscr{N}$-extended superparticle ...

  • Worldsheet methods for perturbative quantum field theory 

    Casali, Eduardo (University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsTrinity College, 2015-10-01)
    This thesis is divided into two parts. The first part concerns the study of the ambitwistor string and the scattering equations, while the second concerns the interplay of the symmetries of the asymptotic null boundary of ...

  • Wrist-Partitioned Inverse Kinematic Accelerations and Manipulator Dynamics 

    Unknown author (1983-04-01)
    An efficient algorithm is presented for the calculation of the inverse kinematic accelerations for a 6 degree-of-freedom manipulator with a spherical wrist. The inverse kinematic calculation is shown to work synergistically ...

  • Writing and Representation 

    Unknown author (MIT Artificial Intelligence Laboratory, 1988-09)
    This paper collects several notes I've written over the last year in an attempt to work through my dissatisfactions with the ideas about representation I was taught in school. Among these ideas are the notion of a 'world ...
