Constant Rate of Loading Nonlinear Consolidation

Soils and Foundations, 1985
ABSTRACT A solution of the problem of one dimensional nonlinear consolidation under constant rate of loading is presented. The computed results of excess pore pressure in the sample are compared with those obtained by the linear theory. A new dimensionless parameter is shown to influence the magnitude of difference between linear and nonlinear ...

Gust Loading Factors with Nonlinear Pressure Terms [PDF]

Journal of the Structural Division, 1978
The purpose of this paper is to develop an analytical expression for the gust loading factor of buildings in which the nonlinear pressure terms are taken into account. The main steps leading to such an expression are presented and numerical examples are given showing the influence of the nonlinear terms on the magnitude of the random response.

Short-Term Electric Load Forecasting of Integrated Energy System Considering Nonlinear Synergy Between Different Loads

IEEE Access, 2021
As an efficient form of energy utilization, an integrated energy system integrates oil, natural gas, coal, and other energy sources and converts them into electric, cooling, and heating for users through energy conversion devices.

Beam Loading in the Nonlinear Regime of Plasma-Based Acceleration [PDF]

Physical Review Letters, 2008
A theory that describes how to load negative charge into a nonlinear, three-dimensional plasma wakefield is presented. In this regime, a laser or an electron beam blows out the plasma electrons and creates a nearly spherical ion channel, which is modified by the presence of the beam load.

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

FEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Hurricane Wave Loads on Spar-Type Floating Wind Turbines: A Comparison of Simulation Schemes

Atmosphere, 2023
Floating wind turbines are sensitive to hurricane events. Since the turbine rotors are parked and the blades are feathered during hurricanes, the aerodynamic loads due to boundary-layer winds are relatively small compared to the hydrodynamic loads due to

Robust load frequency control of nonlinear power networks [PDF]

International Journal of Control, 2018
This paper proposes a decentralised second-order sliding mode (SOSM) control strategy for load frequency control (LFC) in power networks, regulating the frequency and maintaining the net inter-area power flows at their scheduled values. The considered power network is partitioned into control areas, where each area is modelled by an equivalent ...

Type I interferons modulate autophagy to shape gemcitabine response in pancreatic cancer cells

FEBS Open Bio, EarlyView.
Type I interferons differentially modulate autophagy and the response of pancreatic cancer cells to gemcitabine. IFNα2b stimulates autophagic flux and protects cells from gemcitabine‐induced cell death, contributing to chemoresistance. In contrast, IFNβ1a inhibits autophagosome formation and enhances gemcitabine‐induced cell death, resulting in ...
