  • Quality control tools for interactive rendering of 3D triangle meshes 

    Southern, Richard (University of Cape TownFaculty of ScienceDepartment of Computer Science, 2002)
    In this dissertation we explore methods of quality control of untextured polygonal models. The tools presented build, evaluate and improve on the field of multiresolution analysis through decimation. We evaluate the quality ...

  • Quality of service and NFC Communications Security of applications dedicated to dependent people 

    Afolabi-Bello, Oluwayemisi (2016-05-15)
    The application of Near Field Communication (NFC) technology in every part of the world today has tremendously improved efficiency and effectiveness regarding security. The use of this technology in the healthcare system ...

  • Quantification of Uncertainty and Risks for Developing Marginal Fields in the Niger Delta 

    Awotiku, Oluwabiyi Isaac (2011-11-20)
    The Niger Delta is Nigeria’s and Africa’s most prolific producing basin and has some untapped oil resources because of their marginality. The development of marginal oil field in Nigeria has now become an important strategic ...

  • Quantifier-Free Boolean Algebra with Presburger Arithmetic is NP-Complete 

    Unknown author (2007-01-01)
    Boolean Algebra with Presburger Arithmetic (BAPA) combines1) Boolean algebras of sets of uninterpreted elements (BA)and 2) Presburger arithmetic operations (PA). BAPA canexpress the relationship between integer variables ...

  • Quantifying eddy feedbacks and forcings in the tropospheric response to stratospheric sudden warmings 

    Hitchcock, Peter; Simpson, Isla R. (American Meteorological SocietyJournal of the Atmospheric Sciences, 2016-08-26)
    The equatorward shift of the zonal mean midlatitude tropospheric jet following a stratospheric sudden warming in a comprehensive, stratosphere-resolving model is found to be well quantified by a simple model, due to Lorenz ...

  • Quantifying Incremental Oil Production and Economics of using Intelligent Completion as a Tool for Reservoir Management 

    Bentil, Nana Esi (2013-05-25)
    Huge amount of hydrocarbon in place is left unrecovered. Integrated reservoir management, in addition to the use of new technologies improves hydrocarbon recovery. Intelligent completion is one of the technologies which ...

  • Quantifying separability in virtually special groups 

    Hagen, Mark Fearghus; Patel, Priyam (Mathematical Society PublishingPacific Journal of Mathematics, 2016)
    We give a new, effective proof of the separability of cubically convex-cocompact subgroups of special groups. As a consequence, we show that if G is a virtually compact special hyperbolic group, and Q ≤ G is a K-quasiconvex ...

  • Quantifying the Risks of Wellbore Failure during Drilling Operations Using Bayesian Algorithm 

    Adeyemi, Adeyeye Emmanuel (2019-06-23)
    The wellbore integrity plays an important role in petroleum operations like drilling, well completion and production. Caliper, Electrical image logs, Acoustic televiewers (ATV) and Optical televiewers (OTV) are some of the ...

  • Quantitative Aspects of the Computation Performed by Visual Cortex in the Cat, With a Note on a Function of Lateral Inhibition 

    Unknown author (MIT Artificial Intelligence Laboratory, 1973-12)
    A quantitative summary is given of the computation that is performed by visual cortex in the cat. Part of this computation seems to be achieved using a sample-and-average technique; some quantitative features of this ...

  • Quantitative assessment of computational models for retinotopic map formation 

    Hjorth, JJ Johannes; Sterratt, David C; Cutts, Catherine S; Willshaw, David J; Eglen, Stephen John (WileyDevelopmental Neurobiology, 2014-11-14)
    Molecular and activity-based cues acting together are thought to guide retinal axons to their terminal sites in vertebrate optic tectum or superior colliculus (SC) to form an ordered map of connections. The details of ...

  • Quantitative differences in developmental profiles of spontaneous activity in cortical and hippocampal cultures 

    Charlesworth, Paul; Cotterill, Ellese; Morton, Andrew; Grant, Seth GN; Eglen, Stephen John (SpringerNeural Development, 2015-01-28)
    Background: Neural circuits can spontaneously generate complex spatiotemporal firing patterns during development. This spontaneous activity is thought to help guide development of the nervous system. In this study, we had ...

  • Quantitative Inference in a Mechanical Design Compiler 

    Unknown author (1989-01-01)
    This paper presents the ideas underlying a program that takes as input a schematic of a mechanical or hydraulic power transmission system, plus specifications and a utility function, and returns catalog numbers from ...

  • Quantitative Information Flow as Network Flow Capacity 

    Unknown author (2007-12-10)
    We present a new technique for determining how much information abouta program's secret inputs is revealed by its public outputs. Incontrast to previous techniques based on reachability from secretinputs (tainting), it ...

  • Quantitative Information-Flow Tracking for C and Related Languages 

    Unknown author (2006-11-17)
    We present a new approach for tracking programs' use of data througharbitrary calculations, to determine how much information about secretinputs is revealed by public outputs. Using a fine-grained dynamicbit-tracking ...

  • Quantized Skyrmions from SU(4) weight diagrams 

    Halcrow, CJ; Manton, Nicholas Stephen; Rawlinson, JI (Physical Review C, 2018-03-06)
    © 2018 authors. Published by the American Physical Society. Starting from solutions of the lightly bound Skyrme model, we construct many new Skyrmion solutions of the standard Skyrme model with tetrahedral or octahedral ...

  • Quantum communication complexity advantage implies violation of a Bell inequality 

    Buhrman, Harry; Czekaj, Lukasz; Grudka, Andrzej; Horodecki, Michal; Horodecki, Pawel; Markiewicz, Marcin; Speelman, Florian; Strelchuk, Sergii (National Academy of SciencesProceedings of the National Academy of Sciences, 2016-03-08)
