Why Classical Finite difference Approximations fail for a singularly perturbed System of ConvectionDiffusion Equations
(20160607)We consider classical Finite Difference Scheme for a system of singularly perturbed convectiondiffusion 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
(19720201)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
(19720401)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 Threedimensional Objects?
(19920601)When we look at certain linedrawings, we see threedimensional objects. The question is why; why not just see twodimensional 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
(19930701)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
(20080210)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 suboptimal results. Our goal has been to assess our decision ...

WideArea Egomotion Estimation from Known 3D Structure
(20060109)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 cameraÂ s 6DOF egomotion expressed in the ...

Wireless Sensor Networks for Environmental Monitoring Applications
(20160816)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
(19690101)This memo describes a design aid used for the automatic production of wirelists for machine or hand wiring of wirecards.

Witt groups of complex varieties
(University of CambridgeDepartment of Pure Mathematics and Mathematical StatisticsTrinity Hall, 20110712)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 Ktheory. ...

A workflow for geocoding South African addresses
(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 on the Design and Control of Dextrous Hands
(19820401)The Workshop for the Design and Control of Dexterous Hands was held at the MIT Artificial Intelligence Laboratory on November 56, 1981. Outside experts were brought together to discuss four topics: kinematics of hands, ...

World Wide Web Without Walls
(20070824)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
(World Scientific PublishingInternational Journal of Modern Physics A, 20160930)The action for a massless particle in 4D Minkowski space–time has a worldlinetime 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
(University of CambridgeDepartment of Applied Mathematics and Theoretical PhysicsTrinity College, 20151001)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 ...

Worms of Ganymedes  Hazards of Image "Restoration"
(MIT Artificial Intelligence Laboratory, 198009)

WristPartitioned Inverse Kinematic Accelerations and Manipulator Dynamics
(19830401)An efficient algorithm is presented for the calculation of the inverse kinematic accelerations for a 6 degreeoffreedom manipulator with a spherical wrist. The inverse kinematic calculation is shown to work synergistically ...

Writing and Representation
(MIT Artificial Intelligence Laboratory, 198809)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 ...
