Constructing security in today's world.Constructing International Security helps policy makers and students recognize effective third-party strategies for balancing deterrence and restraint in security relationships. Brett V. Benson shows that there are systematic differences among types of security commitments. Understanding these commitments is key, because commitments, such as formal military alliances and extended deterrence threats, form the basis of international security order. Benson argues that sometimes the optimal commitment conditions military assistance on specific hostile actions the adversary might take. At other times, he finds, it is best to be ambiguous by leaving an ally and adversary uncertain about whether the third party will intervene. Such uncertainty transfers risk to the ally, thereby reducing the ally's motivation to behave too aggressively. The choice of security commitment depends on how well defenders can observe hostilities leading to war and on their evaluations of dispute settlements, their ally's security and the relative strength of the defender.Security, InternationalSecurity, International.355/.031POL011000bisacshBenson Brett V.1973-1499803UkCbUPUkCbUPBOOK9910779345203321Constructing international security3726200UNINA03924nam 2200637 450 991080722050332120201203183643.01-4704-6251-6(CKB)4100000011437133(MiAaPQ)EBC6346623(RPAM)21655465(PPN)250799588(EXLCZ)99410000001143713320201203d2020 uy 0engurcnu||||||||txtrdacontentcrdamediacrrdacarrierDynamics near the subcritical transition of the 3D Couette flow I below threshold case /Jacob Bedrossian, Pierre Germain, Nader MasmoudiProvidence, RI :American Mathematical Society,[2020]©20201 online resource (v, 158 pages)Memoirs of the American Mathematical Society ;Number 1294"July 2020, volume 266, number 1294 (fourth of 6 numbers)."1-4704-4217-5 Includes bibliographical references and index.Outline of the proof -- Regularization and continuation -- High norm estimate on Q2 -- High norm estimate on Q3 -- High norm estimate on Q1/0 -- High norm estimate on Q1/[not equal] -- Coordinate system controls -- Enhanced dissipation estimates -- Sobolev estimates."We study small disturbances to the periodic, plane Couette flow in the 3D incompressible Navier-Stokes equations at high Reynolds number Re. We prove that for sufficiently regular initial data of size [epsilon] [less than or equal to] c0Re-1 for some universal c0 > 0, the solution is global, remains within O(c0) of the Couette flow in L2, and returns to the Couette flow as t [right arrow] [infinity]. For times t >/-Re1/3, the streamwise dependence is damped by a mixing-enhanced dissipation effect and the solution is rapidly attracted to the class of "2.5 dimensional" streamwise-independent solutions referred to as streaks. Our analysis contains perturbations that experience a transient growth of kinetic energy from O(Re-1) to O(c0) due to the algebraic linear instability known as the lift-up effect. Furthermore, solutions can exhibit a direct cascade of energy to small scales. The behavior is very different from the 2D Couette flow, in which stability is independent of Re, enstrophy experiences a direct cascade, and inviscid damping is dominant (resulting in a kind of inverse energy cascade). In 3D, inviscid damping will play a role on one component of the velocity, but the primary stability mechanism is the mixing-enhanced dissipation. Central to the proof is a detailed analysis of the interplay between the stabilizing effects of the mixing and enhanced dissipation and the destabilizing effects of the lift-up effect, vortex stretching, and weakly nonlinear instabilities connected to the non-normal nature of the linearization"--Provided by publisher.Memoirs of the American Mathematical Society ;Number 1294.Inviscid flowMixingShear flowStabilityThree-dimensional modelingDamping (Mechanics)Viscous flowMathematical modelsInviscid flow.Mixing.Shear flow.Stability.Three-dimensional modeling.Damping (Mechanics)Viscous flowMathematical models.532.5835B3576E0576E3076F0676F1035B4076F25mscBedrossian Jacob1984-1432124Germain Pierre1979-Masmoudi Nader1974-MiAaPQMiAaPQMiAaPQBOOK9910807220503321Dynamics near the subcritical transition of the 3D Couette flow I4071607UNINA
