Spreading of a surfactant monolayer on a thin liquid film: Onset and evolution of digitated structures [PDF]

open access: yes, 1999
We describe the response of an insoluble surfactant monolayer spreading on the surface of a thin liquid film to small disturbances in the film thickness and surfactant concentration.

Characteristics of NOx Formation and Removal in the Transient Process of a 660 MW Coal-fired Power Unit

open access: yes发电技术, 2020
In order to complete the peak load regulating of power system, coal-fired power units have long-term frequent load fluctuations, which have a significant impact on the formation and removal of nitrogen oxides. In this paper, with the goal of studying the

Intermediate Palomar Transient Factory: Realtime Image Subtraction Pipeline [PDF]

open access: yes, 2016
A fast-turnaround pipeline for realtime data reduction plays an essential role in discovering and permitting follow-up observations to young supernovae and fast-evolving transients in modern time-domain surveys.

Some Asymptotic Results for the Transient Distribution of the Halfin-Whitt Diffusion Process [PDF]

open access: yes, 2013
We consider the Halfin-Whitt diffusion process $X_d(t)$, which is used, for example, as an approximation to the $m$-server $M/M/m$ queue. We use recently obtained integral representations for the transient density $p(x,t)$ of this diffusion process, and ...

Software Control of Machines Based on Typification of Transient Zone Parameters for Processing of Original Non-Circular Parts

open access: yesМеханика машин, механизмов и материалов
The paper provides an overview of trends in the preparation of control programs for CNC metal cutting machines. The direction in the development of programming of machining parts based on the transient zone parameter typification is described.

Analysis of Transient Processes in a Radiophysical Flow System

open access: yes, 2006
Transient processes in a third-order radiophysical flow system are studied and a map of the transient process duration versus initial conditions is constructed and analyzed.

Transient Simulation of Underground Pumped Storage Hydropower Plants Operating in Pumping Mode

open access: yesEnergies, 2020
The increasing penetration of variable renewable energies (VRE) in the European electricity mix requires flexible energy storage systems (ESS), such as pumped storage hydropower (PSH). Disused mining voids from deep closed mines may be used as subsurface

A multispecies birth-death-immigration process and its diffusion approximation

open access: yes, 2016
We consider an extended birth-death-immigration process defined on a lattice formed by the integers of $d$ semiaxes joined at the origin. When the process reaches the origin, then it may jumps toward any semiaxis with the same rate.

Modified Bloch equations in presence of a nonstationary bath [PDF]

open access: yes, 1999
Based on the system-reservoir description we propose a simple solvable microscopic model for a nonequilibrium bath. This captures the essential features of a nonstationary quantum Markov process.
