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

Complex & 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 ...

A Theoretical γ Doradus Instability Strip

The Astrophysical Journal, 2003
In this paper, we present the first theoretical γ Doradus instability strip. We find that our model instability strip agrees very well with the previously established, observationally based, instability strip of Handler & Shobbrook. We stress, as do Guzik et al., that the convection zone depth plays the major role in the determination of our ...

Strip lateral position control using electromagnets in continuous processing line

Mechanical 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

Shock 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.

Convective effects and the RR lyrae instability strip [PDF]

Symposium - International Astronomical Union, 1984
The effects of nonlinear, nonlocal, diffusive convection have been included in the structure equations of pulsational hydrodynamic analyses of a series of RR Lyrae models. We find a well-defined red edge of the unstable region that depends on mode of pulsation.

Dynamics of Large-Scale Plastic Deformation and the Necking Instability in Amorphous Solids

, 2002
We use the shear transformation zone (STZ) theory of dynamic plasticity to study the necking instability in a two-dimensional strip of amorphous solid. Our Eulerian description of large-scale deformation allows us to follow the instability far into the ...

Dynamical Instabilities of Quasi-static Crack Propagation Under Thermal Stress [PDF]

, 2003
We address the theory of quasi-static crack propagation in a strip of glass that is pulled from a hot oven towards a cold bath. This problem had been carefully studied in a number of experiments that offer a wealth of data to challenge the theory.

The Faint Cepheids of the Small Magellanic Cloud: an evolutionary selection effect?

, 2003
Two problems about the faintest Small Magellanic Cloud (SMC) Cepheids are addressed. On one hand evolutionary tracks fail to cross the Cepheid Instability Strip for the highest magnitudes (i.e.

Spectrum Analysis of Bright Kepler Gamma Doradus Candidate Stars [PDF]

, 2012
Ground-based spectroscopic follow-up observations of the pulsating stars observed by the Kepler satellite mission are needed for their asteroseismic modelling.

“Constant” eclipsing binary in the instability strip

New Astronomy, 2015
Abstract The eclipsing binary OO Peg consist of two late-A type stars in circular orbit with a period of 2.985 days. I use the high-resolution spectroscopic and extensive light curves from the ASAS and Hipparcos survey to measure the physical properties of the system.
