Influence of multiple islands on the hysteresis and dynamics of a western boundary current perturbed by a mesoscale eddy at a gap

open access: yesFrontiers in Marine Science, 2023
The hysteresis of a western boundary current (WBC) flowing across a gap and the dynamics of the mesoscale eddy–WBC interaction with the presence of two islands in the gap are studied using a 1.5-layer ocean model.

Critical temperature and energy gap for the BCS equation [PDF]

open access: yesPhysical Review B, 2008
We derive upper and lower bounds on the critical temperature $T_c$ and the energy gap $Ξ$ (at zero temperature) for the BCS gap equation, describing spin 1/2 fermions interacting via a local two-body interaction potential $λV(x)$. At weak coupling $λ\ll 1$ and under appropriate assumptions on $V(x)$, our bounds show that $T_c \sim A \exp(-B/λ)$ and $Ξ ...

Cubic critical portraits and polynomials with wandering gaps [PDF]

open access: yesErgodic Theory and Dynamical Systems, 2012
AbstractThurston introduced $\sigma _d$-invariant laminations (where $\sigma _d(z)$ coincides with $z^d:\mathbb S ^1\to \mathbb S ^1$, $d\ge 2$) and defined wandering $k$-gons as sets ${\mathbf {T}}\subset \mathbb S ^1$ such that $\sigma _d^n({\mathbf {T}})$ consists of $k\ge 3$ distinct points for all $n\ge 0$ and the convex hulls of all the sets ...

Estimation of a Critical Gap/ Lag in Uncontrolled Intersections in Sri Lanka [PDF]

open access: yesJournal of South Asian Logistics and Transport
The critical gap/lag value for an uncontrolled intersection is an important parameter in estimating highway traffic capacity and developing micro stimulations of traffic movements.

Analyzing variations in spatial critical gaps at two-way stop controlled intersections using parametric and non-parametric techniques

open access: yesJournal of Traffic and Transportation Engineering (English ed. Online), 2021
At two-way stop controlled (TWSC) intersections drivers on minor stream are generally at risk because of the difficulty in judging safe gap between major stream vehicles.
