In some cases water droplets can completely wet microstructured superhydrophobic surfaces. The dynamics of this rapid process is analyzed by ultrahigh-speed imaging. Depending on the scales of the microstructure, the wetting fronts propagate smoothly and circularly or-more interestingly-in a stepwise manner, leading to a growing square-shaped wetted area: entering a new row perpendicular to the...

In the literature, estimators for regression or multivariate location and dispersion that have been shown to be both consistent and high breakdown are impractical to compute. This paper gives easily computed high breakdown robust √ n consistent estimators, and the applications for these estimators are numerous. For regression, the response plot of the fitted values versus the response is shown ...

X-band accelerator structures meeting the Next Linear Collider (NLC) design requirements have been found to suffer damage due to Radio Frequency (RF) breakdown when processed to high gradients [F. Le Pimpec, et al., in: LINAC 2002, Korea, SLAC-PUB-9526, 2002 [1]]. Improved understanding of these breakdown events is desirable for the development of structure designs, fabrication procedures, and ...

Titanium is a highly reactive metal so that a thin layer of oxide forms on its surface whenever exposed to the air or other environments containing oxygen. This layer increases the corrosion resistance of titanium. The oxide film is electrochemically formed through anodizing. In this study, anodizing of titanium was performed in phosphate-base solutions such as H3Po4, NaH2Po4, and Na2Hpo4 at 9....

This paper presents a new mathematical model to solve cell formation problem in cellular manufacturing systems, where inter-arrival time, processing time, and machine breakdown time are probabilistic. The objective function maximizes the number of operations of each part with more arrival rate within one cell. Because a queue behind each machine; queuing theory is used to formulate the model. T...

background: nasal continuous positive airway pressure (ncpap) is an effective method of ventilation in newborns with respiratory distress syndrome (rds). using an appropriate nasal skin care protocol is identical to prevention or reduction of nasal skin breakdown in those who receive ncpap. this study aimed to investigate the effectiveness of an evidence-based clinical care protocol on nasal sk...

We thank all the discussants for their contributions and in particular we wish to thank Hampel. The concept of breakdown point goes back to his Ph.D. thesis [Hampel (1968)] and he was the first to exhibit a high breakdown equivariant regression estimate now known as the least median of squares [Hampel (1975)], a fact which is sometimes forgotten. These two sources are the starting point of the ...
