On the tail asymptotics of the area swept under the Brownian storage graph [PDF]

open access: yes, 2014
In this paper, the area swept under the workload graph is analyzed: with $\{Q(t) : t\ge0\}$ denoting the stationary workload process, the asymptotic behavior of \[\pi_{T(u)}(u):={\mathbb{P}}\biggl(\int_0^ {T(u)}Q(r)\,\mathrm{d}r>u\biggr)\] is analyzed ...

Energy Efficiency Optimization Design of a Forward-Swept Axial Flow Fan for Heat Pump

open access: yesFrontiers in Energy Research, 2021
As one of the key components of the heat pump system, compared to that of a conventional axial fan, the blade tip area of a forward-swept axial fan is much larger than its blade root, which is the main noise source of the fan and also has an important ...

The Dynamics Of Vortex And Monopole Production By Quench Induced Phase Separation [PDF]

open access: yes, 1994
Our understanding of the mechanism by which topological defects are formed in symmetry breaking phase transitions has recently changed. We examine the non-equilibrium dynamics of defect formation for weakly-coupled global O(N) theories possessing ...

Problems of ensuring traffic flow on a Basic turbo roundabout with non-standard curvilinear entries (a case study) [PDF]

open access: yesPrzegląd Komunikacyjny, 2023
: With ever-increasing motorisation and the desire for greater traffic safety, conventional roundabouts and turbo roundabouts are being designed. Turbo roundabouts provide greater traffic safety than conventional roundabouts due to the segregation of ...

Optimization of integrated geological-engineering design of volume fracturing with fan-shaped well pattern

open access: yesPetroleum Exploration and Development, 2023
According to the variable toe-to-heel well spacing, combined with the dislocation theory, discrete lattice method, and finite-element-method (FEM) based fluid-solid coupling, an integrated geological-engineering method of volume fracturing for fan-shaped

Statistics of the first passage time of Brownian motion conditioned by maximum value or area [PDF]

open access: yes, 2014
We derive the moments of the first passage time for Brownian motion conditioned by either the maximum value or the area swept out by the motion. These quantities are the natural counterparts to the moments of the maximum value and area of Brownian ...

Correlations among age, sex, axial length, and subfoveal choroidal thickness in the choriocapillaris structure analyzed using multiple en face image averaging optical coherence tomography angiography.

open access: yesPLoS ONE, 2021
PurposeTo analyze the structure of the choriocapillaris in healthy eyes by using averaged en face images acquired using swept source optical coherence tomography angiography and to examine the changes in the macular profile in relation to age, sex, axial

Correction of wavelength-dependent laser fluence in swept-beam spectroscopic photoacoustic imaging with a hand-held probe

open access: yesPhotoacoustics, 2020
Recently, we demonstrated an integrated photoacoustic (PA) and ultrasound (PAUS) system using a kHz-rate wavelength-tunable laser and a swept-beam delivery approach.
