Vibration prediction and analysis of strip rolling mill based on XGBoost and Bayesian optimization

open access: yesComplex & Intelligent Systems, 2022
The stable operation of strip rolling mill is the key factor to ensure the stability of product quality. The design capability of existing domestic imported and self-developed strip rolling mills cannot be fully developed, and the frequent occurrence of ...

Strip lateral position control using electromagnets in continuous processing line

open access: yesMechanical Engineering Journal, 2015
In continuous metal strip processing lines, such as pickling, annealing and surface treatment lines, lateral instability of strips is a common problem. Strip lateral movement has a bad influence on productivity of the processing lines.

Research on Evaluation Index and Application of Rockburst Risk in Deep Strip Mining

open access: yesShock and Vibration, 2020
The practice shows that deep strip mining induces rockburst disaster easily. Accurately evaluating rockburst risk of the strip coal pillar is of great significance for ensuring the safety of deep strip mining.

New developments of the ZZ Ceti instability strip : the discovery of 11 new variables [PDF]

open access: yes, 2010
Using the The SOuthern Astrophysical Research (SOAR) 4.1-m telescope, we report on the discovery of low amplitude pulsations for three stars previously reported as not-observed-to-vary (NOV) by Mukadam et al.

Dynamic Stability of Moderately Thick Composite Laminated Skew Plates using Finite Strip Method [PDF]

open access: yesMechanics of Advanced Composite Structures, 2015
The dynamic instability regions of composite laminated skew flat plates subjected to uniform in-plane axial end-loading are investigated. The in-plane loading is assumed as a combination of a time-invariant component and a harmonic time-varying component

AMPLITUDE FINE STRUCTURE IN THE CEPHEID P–L RELATION. I. AMPLITUDE DISTRIBUTION ACROSS THE RR LYRAE INSTABILITY STRIP MAPPED USING THE ACCESSIBILITY RESTRICTION IMPOSED BY THE HORIZONTAL BRANCH [PDF]

open access: yes, 2010
The largest amplitude light curves for both RR Lyrae (RRL) variables and classical Cepheids with periods less than 10 days and greater than 20 days occur at the blue edge of the respective instability strips.

FINDING THE INSTABILITY STRIP FOR ACCRETING PULSATING WHITE DWARFS FROM HUBBLE SPACE TELESCOPE AND OPTICAL OBSERVATIONS [PDF]

open access: yes, 2009
Time-resolved low resolution Hubble Space Telescope ultraviolet spectra together with ground-based optical photometry and spectra are used to constrain the temperatures and pulsation properties of six cataclysmic variables containing pulsating white ...

Temperature Differences in the Cepheid Instability Strip Require Differences in the Period-Luminosity Relation in Slope and Zero Point [PDF]

open access: yes, 2008
A graphical and an algebraic demonstration is made to show why the slope and zero point of the Cepheid period-luminosity (P-L) relation is rigidly coupled with the slope and zero point of the Cepheid instability strip in the HR diagram. In this way it is

Deep Transverse Lateral Retinaculum Reconstruction for Medial Patellar Instability

open access: yesArthroscopy Techniques, 2015
Medial patellar instability can be a disabling complication of an extensive lateral retinaculum release. It is often overlooked, and for the diagnosis, it is necessary to have a high index of suspicion.
