Stationary stochastic Navier–Stokes on the plane at and above criticality
Stochastics and Partial Differential Equations: Analysis and Computations, 2023 AbstractIn the present paper, we study the fractional incompressible Stochastic Navier–Stokes equation on $${\mathbb {R}}^2$$ R 2 , formally defined as $$\begin{aligned} \partial _t v = -\tfrac{1}{2} (-\Delta ...

Critical temperature of two coupled Ising planes [PDF]
Physical Review B, 1995 It is shown that the method proposed by Wosiek [Phys. Rev. B 49, 15 023 (1994)] for the calculation of the order-disorder critical temperature, which turns out to be exact when the critical temperature is determined by symmetry properties like self-duality, is, when applied to a system of two coupled Ising planes, the lowest-order approximation in a ...

Critical Layer Analysis of Stuart Vortices in a Plane Jet [PDF]
Mathematical Problems in Engineering, 2014 Asymptotic techniques are used to model quasi‐steady‐state vortices in the plane (Bickley) inviscid jet. A nonlinear critical layer analysis is used to find a family of steady‐state finite amplitude two‐dimensional vortices which are based on the Stuart vortex.

Fatigue assessment of a FSAE car rear upright by a closed form solution of the critical plane method
Fracture and Structural IntegrityMaterial fatigue is extensively discussed and researched within scientific and industrial communities. Fatigue damage poses a significant challenge for both metallic and non-metallic components, often resulting in unexpected failures of in-service parts.

Identification of critical transmission limits in injection impedance plane [PDF]
International Journal of Electrical Power & Energy Systems, 2012 Abstract In this paper, equations are derived that describe the mapping of critical boundaries and characteristic curves from the three dimensional PQV-surface into the two-dimensional injection impedance plane (load impedance plane for both positive and negative resistance).
