Constraints on Dbar Uplifts [PDF]

open access: yes, 2016
We discuss constraints on KKLT/KKLMMT and LVS scenarios that use anti-branes to get an uplift to a deSitter vacuum, coming from requiring the validity of an effective field theory description of the physics.

Constraint Programming [PDF]

open access: yesRevue Ouverte d'Intelligence Artificielle, 2000
This article recounts the story of constraint programming, one of the most remarkable and enduring scientific contributions of Alain Colmerauer. It is a personal story, having lived through, and contributed to, the events that are reported here.

Desires, norms and constraints [PDF]

open access: yes, 2004
This paper deals with modeling mental states of a rational agent, in particular states based on agent’s desires. It shows that the world the agent belongs to forces it to restrict its desires. More precisely, desires of a rational agent are restricted by

Farmers’ knowledge and perceptions of virus diseases affecting hot pepper and their management in Rwanda

open access: yesFundamental and Applied Agriculture, 2020
Hot pepper (Capsicum spp.) is an important cash crop in Rwanda however, its productivity can only increase after addressing factors that limit its production.

Composition with Target Constraints [PDF]

open access: yes, 2010
It is known that the composition of schema mappings, each specified by source-to-target tgds (st-tgds), can be specified by a second-order tgd (SO tgd). We consider the question of what happens when target constraints are allowed.

Constraint acquisition

open access: yesArtificial Intelligence, 2017
Constraint programming is used to model and solve complex combina- torial problems. The modeling task requires some expertise in constraint programming. This requirement is a bottleneck to the broader uptake of constraint technology. Several approaches have been proposed to assist the non-expert user in the modelling task. This paper presents the basic

Constraints on Neutrino Mixing [PDF]

open access: yes, 1999
We explore the implications of imposing the constraint that two neutrino flavors (which for definiteness we take to be the mu and tau neutrinos) are similarly coupled to the mass basis in addition to the unitarity constraints.

Constraint Fluids

open access: yesIEEE Transactions on Visualization and Computer Graphics, 2012
We present a fluid simulation method based on Smoothed Particle Hydrodynamics (SPH) in which incompressibility and boundary conditions are enforced using holonomic kinematic constraints on the density. This formulation enables systematic multiphysics integration in which interactions are modeled via similar constraints between the fluid pseudoparticles

Linear constraints from generally covariant systems with quadratic constraints

open access: yes, 2006
How to make compatible both boundary and gauge conditions for generally covariant theories using the gauge symmetry generated by first class constraints is studied.

Constraints in Quantum Geometrodynamics [PDF]

open access: yes, 2003
We compare different treatments of the constraints in canonical quantum gravity. The standard approach on the superspace of 3--geometries treats the constraints as the sole carriers of the dynamic content of the theory, thus rendering the traditional ...
