ARL‐Unbiased Exponential Control Charts With Estimated Parameters: Statistical Design and Implementation

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT The bias of a control chart is an important factor in practical applications. Average run length (ARL)‐biased control charts have their out‐of‐control (OOC) ARL (ARLOOC) greater than the in‐control (IC) ARL (ARLin) for some values of the monitored parameter.

Effect of Freeze–Thaw Action on Mesostructure of Ecological Fiber Reinforced Loess

open access: yesAdvances in Civil Engineering
Traditional chemical additives inevitably pollute, damage, and destroy the ecological environment and natural resources while simultaneously addressing the requirements of engineering construction in loess areas.

Stability of Monitoring Weak Changes in Multiply Scattering Media with Ambient Noise Correlation: Laboratory Experiments [PDF]

open access: yes, 2009
Previous studies have shown that small changes can be monitored in a scattering medium by observing phase shifts in the coda. Passive monitoring of weak changes through ambient noise correlation has already been applied to seismology, acoustics and ...

Subglacial landscape formation and sediment discharge: relating basal conditions to bedform dimensions and properties at Rutford Ice Stream, West Antarctica

open access: yesBoreas, EarlyView.
Basal conditions that facilitate fast ice flow are still poorly understood and their parameterization in ice‐flow models results in high uncertainties in ice‐flow and consequent sea‐level rise projections. Direct observations of basal conditions beneath modern ice streams are limited due to the inaccessibility of the bed.

Large amplitude oscillations in prominences [PDF]

open access: yes, 2009
Since the first reports of oscillations in prominences in the 1930s, there have been major theoretical and observational developments to understand the nature of these oscillatory phenomena, leading to the whole new field of the so-called “prominence ...

Horizontal Clusters and Firm Resilience

open access: yesJournal of Regional Science, EarlyView.
ABSTRACT The paper examines the role that cluster‐specific horizontal relationships play in firm resilience following a negative shock. We use the Emilia earthquake that hit part of Emilia‐Romagna (Italy) in May 2012 to provide evidence of the negative effect of horizontal clustering on firm performance after a natural disaster.

Field Testing and Numerical Simulation of the Dynamic Response of Loess Hill Site under High-Speed Train Load

open access: yesShock and Vibration
In this study, the loess hill site of an elevated bridge section in Tongwei-Qin’an of the Baolan high-speed railroad was selected as the research object, and the vibration acceleration of the loess hill site under the elevated bridge was tested in the ...

Comparative seismology of pre- and main sequence stars in the instability strip [PDF]

open access: yes, 2001
Pulsational properties of 1.8 M$_{\odot}$ stellar models covering the latest stages of contraction toward the main sequence up to early hydrogen burning phases are investigated by means of linear nonadiabatic analyses.

Drainage Divide Migration in Response to Asymmetric Uplift at Eastern Qinling, China

open access: yesTerra Nova, EarlyView.
ABSTRACT Drainage divide migration shapes landscape, sediment patterns, and biodiversity, which is affected by a variety of factors. While geomorphic index and numerical simulations have been employed to investigate divide migration, previous studies ignore the present‐day vertical velocity field.
