ABS Control of Electronic Mechanical Braking System Based on Integral Sliding Mode [PDF]

open access: yesZhengzhou Daxue xuebao. Gongxue ban
In order to solve the disadvantages of traditional brake system logic threshold control, which was complicated in logic and difficult to make full use of road adhesion, and the problems of nonlinearity and uncertainty of ABS, a control strategy of ABS ...

The Slip Transfer Process Through Grain Boundaries in HCP Ti

open access: yes, 1993
Information on the mechanisms of slip transfer across grain boundaries in an HCP α-Ti alloy has been obtained from deformation experiments performed In situ in the transmission electron microscope.

Leakage flow-induced vibration of an eccentric tube-in-tube slip joint

open access: yes, 1985
Eccentricity of a specific slip-joint design separating two cantilevered, telescoping tubes did not create any self-excited lateral vibrations that had not been observed previously for a concentric slip joint. In fact, the eccentricity made instabilities

Analysis of Brownian motion and thermophoresis effects with chemical reaction on Williamson nanofluid flow over permeable stretching sheet

open access: yesPartial Differential Equations in Applied Mathematics
This study warrants a broad analysis on the simultaneous effects of Brownian and thermophoresis on the chemically reacting Williamson nanofluid flow via a permeable expanding sheet.

Constraints on transient glacier slip with ice-bed separation

open access: yes, 2022
Glacier slip facilitates fast glacier flow and modulates sea-level rise, but empirical constraints on slip-controlling processes at relevant scales are limited.

Finite Time Adaptive Sliding Mode Control of Multi-agent Systems via Unknown External Disturbance and Undirected Network [PDF]

open access: yesمکانیک هوافضا, 2023
In this paper, the finite time control of 2nd order multi-agent systems (MASs) consisting of a leader and a number of followers under external disturbance is discussed.

Normative expression and accurate understanding of focal mechanism parameters

open access: yesGeosystems and Geoenvironment, 2023
This paper aims at the understanding of the relationship between the upper and lower hemisphere projection maps of the focal sphere, the correct reading of the focal mechanism parameters on the projection diagram, and to investigate if there is ...

Hybrid molecular and continuum fluid dynamics models for micro and nanofluidic flows [PDF]

open access: yes, 2009
From molecules to living organisms and from atoms to planets a variety of physical phe- nomena operate at different temporal and spatial scales. Understanding the nature of those phenomena is crucial for advancing new technologies in many disciplines ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Effect of anchorage slip and inelastic shear on seismic response of reinforced concrete frames.

open access: yes, 1993
Reinforced Concrete structures located in regions of high seismic activity are expected to develop inelastic deformations in their critical regions. Therefore, inelastic dynamic analysis is required to obtain reliable predictions of structural behavior ...
