Algebraic boundaries of Hilbert's SOS cones
(Cambridge University PressCompositio Mathematica, 2012-10-15)We study the geometry underlying the difference between nonnegative polynomials and sums of squares. The hypersurfaces that discriminate these two cones for ternary sextics and quaternary quartics are shown to be ...

Algebraic Functions For Recognition
(1994-01-01)In the general case, a trilinear relationship between three perspective views is shown to exist. The trilinearity result is shown to be of much practical use in visual recognition by alignment --- yielding a direct method ...

An Algorithm for Bootstrapping Communications
(2001-08-13)I present an algorithm which allows two agents to generate a simple language based only on observations of a shared environment. Vocabulary and roles for the language are learned in linear time. Communication is robust and ...

An Algorithm for Group Formation and Maximal Independent Set in an Amorphous Computer
(1998-02-01)Amorphous computing is the study of programming ultra-scale computing environments of smart sensors and actuators cite{white-paper}. The individual elements are identical, asynchronous, randomly placed, embedded and ...

An Algorithm for Parsing Flow Graphs
(1984-03-01)This report describes research about flow graphs - labeled, directed, acyclic graphs which abstract representations used in a variety of Artificial Intelligence applications. Flow graphs may be derived from flow ...

An Algorithm for Solutions of Hammerstein Integral Equations with Monotone Operators
(2016-06-07)Let X be a uniformly convex and uniformly smooth real Banach space with dual space X ∗ . Let F : X → X ∗ and K : X ∗ → X be bounded monotone mappings such that the Hammerstein equation u + KF u = 0 has a solution in X. An ...

Algorithms for Approximating fixed Points of Multivalued Quasi-Nonexpansive Mappings in Banach Spaces
(AUST, 2019-06-14)Let E be a strictly convex real Banach space and let D ⊆ E be a non-empty closed convex subset of E. Let {T}i∈I be a finite family of quasi-nonexpansive multivalued map which are continuous with respect to the Hausdorff ...

Algorithms for Approximation of Solutions of Equations Involving Nonlinear Monotone-Type and Multi-Valued Mappings
(2015-07-13)It is well know that many physically significant problems in different areas of re- search can be transformed into an equation of the form Au = 0, (0.0.1) where A is a nonlinear monotone operator from a real Banach space ...

Algorithms For Approximation of J-Fixed Points of Nonexpansive - Type Maps, Zeros of Monotone Maps, Solutions of Feasibility and Variational Inequality Problems
(AUST, 2019-07-05)It is well known that many physically significant problems in different areas of research can be transformed at equilibrium state into an inclusion problem of the form 0 ∈ Au, where A is either a multi-valued accretive map ...

Algorithms for efficiently and effectively matching agents in microsimulations of sexually transmitted infections
(University of Cape TownFaculty of ScienceDepartment of Computer Science, 2018)Mathematical models of the HIV epidemic have been used to estimate incidence, prevalence and life-expectancy, as well the benefits and costs of public health interventions, such as the provision of antiretroviral treatment. ...

Alignment by Maximization of Mutual Information
(1995-03-01)A new information-theoretic approach is presented for finding the pose of an object in an image. The technique does not require information about the surface properties of the object, besides its shape, and is robust ...

The Alignment of Objects with Smooth Surfaces
(1988-07-01)This paper examines the recognition of rigid objects bounded by smooth surfaces using an alignment approach. The projected image of such an object changes during rotation in a manner that is difficult to predict. A ...

The Alignment of Objects With Smooth Surfaces: Error Analysis of the Curvature Method
(1991-11-01)The recognition of objects with smooth bounding surfaces from their contour images is considerably more complicated than that of objects with sharp edges, since in the former case the set of object points that generates ...

Alkali Activation and Natural Fiber Reinforcement of Termite Mound Soil for Sustainable, Low Cost and Environmentally Friendly Construction Materials
(2021-04-15)In the construction field, development of green, sustainable and renewable materials is the main focus of research. In that direction, alkali activation technique has attracted a lot of attention in the past few years. ...

Alloy*: A Higher-Order Relational Constraint Solver
(2014-09-02)The last decade has seen a dramatic growth in the use of constraint solvers as a computational mechanism, not only for analysis and synthesis of software, but also at runtime. Solvers are available for a variety of logics ...

Alpenhorn: Bootstrapping Secure Communication without Leaking Metadata
(2016-10-05)Alpenhorn is the first system for initiating an encrypted connection between two users that provides strong privacy and forward secrecy guarantees for metadata (i.e., information about which users connected to each other) ...

Alpha invariants and coercivity of the Mabuchi functional on Fano manifolds
(Université Paul SabatierAnnales de la Faculté des Sciences de Toulouse, 2016)We give a criterion for the coercivity of the Mabuchi functional for general Kàhler classes on Fano manifolds in terms of Tian's alpha invariant. This generalises a result of Tian in the anti-canonical case implying the ...

Alpha Invariants and K-Stability for General Polarizations of Fano Varieties
(Oxford University PressINTERNATIONAL MATHEMATICS RESEARCH NOTICES, 2014-09-26)We provide a sufficient condition for polarisations of Fano varieties to be K-stable in terms of Tian’s alpha invariant, which uses the log canonical threshold to measure singularities of divisors in the linear system ...

The Alpha-Beta Heuristic
(1961-12-01)The Alpha-Beta heuristic is a method for pruning unneeded branches from the move tree of a game. The algorithm makes use of information gained about part of the tree to reject those branches which will not affect the ...
