Electrostatic stresses can overcome surface tension on water-based dust grains, causing them to elongate.

In order to improve this phenomenon, the 3D calculation model on the GSF of trench wall is established by assuming the sliding surface to be a quarter ellipsoidal surface and the sliding mass to be a ...

Recently, high concentrations of hydrogen in soil gas have been observed in shallow, ellipsoidal surface depressions known colloquially as “fairy circles” or Carolina bays. 14 These features ...

Microsoft has kicked off its AI PC revolution with the launch of the Surface Pro 11, which has an optional OLED display, a new and improved Surface Pro Flex keyboard and, of course, a ton of AI ...

Optical Surfaces routinely produces ellipsoidal mirrors in a range of materials (Zerodur, BK7, fused silica) with typical surface accuracy of better than lambda/10 (dependent on size and radius ...

ABSTRACT: Maritime radar and automatic identification systems (AIS), which are essential auxiliary equipment for navigation safety in the shipping industry, have played significant roles in maritime ...

Optical Surfaces routinely produces ellipsoidal mirrors in a range of materials (Zerodur, BK7, fused silica) with typical surface accuracy of better than lambda/10 (dependent on size and radius) and ...

The surface geometry of each fossa prosthesis type was extracted ... 2010), with a friction coefficient of 0.001 (Xu et al., 2017). We developed the ellipsoidal fossa prosthesis based on the lower ...

In 1917 D’Arcy Thompson observed that the pair of antlers of a red deer, a sambur or a wapiti Make up between them a single surface that is more or less spherical or occasionally an ellipsoidal ...
