Cavitation Erosion Pits and Craters in Metals
Semina: Ciências Exatas e Tecnológicas, 2017 Cavitation pits and erosion were obtained using the rotating disk device, where a steel disk with cavitation inducers and specimens fixed on it rotates inside a water chamber to provide the cavitating flow.

Depth of Cracking beneath Impact Craters: New Constraint for Impact Velocity [PDF]
, 2002 Both small-scale impact craters in the laboratory and less than 5 km in diameter bowl-shaped craters on the Earth are strength (of rock) controlled. In the strength regime, crater volumes are nearly proportional to impactor kinetic energy.

Crater population and resurfacing of the Martian north polar layered deposits [PDF]
, 2010 Present-day accumulation in the north polar layered deposits (NPLD) is thought to occur via deposition on the north polar residual cap. Understanding current mass balance in relation to current climate would provide insight into the climatic record of ...

Surface ages of mid-size Saturnian satellites [PDF]
, 2015 The observations of the surfaces of the mid sized Saturnian satellites made by Cassini Huygens mission have shown a variety of features that allows study of the processes that took place and are taking place on those worlds.

On the persistency of crater assignment criteria for Stromboli explosion-quakes
Annals of Geophysics, 1996 On the basis of the results of previous works by our group, this paper aims to investigate the correlation between features of a kind of seismic events recorded at Stromboli (the so called explosion-quakes) and the source of such explosions, i.e.

Determination of the Size and Depth of Craters on the Moon
Center for Educational Policy Studies Journal, 2018 Experimental work in the research of astronomical phenomena is often difficult or even impossible because of long-lasting processes or too distant objects and correspondingly too expensive equipment. In this paper, we present an example of observation of

A Multi-Annotator Survey of Sub-km Craters on Mars
Data, 2020 We present here a dataset of nearly 5000 small craters across roughly 1700 km2 of the Martian surface, in the MC-11 East quadrangle. The dataset covers twelve 2000-by-2000 pixel Context Camera images, each of which is comprehensively labelled by six ...

Geology of the Debussy quadrangle (H14), Mercury
Journal of Maps, 2021 Mercury’s Debussy Quadrangle (H14) lies between 0–90° E and 22.5–65° S. Here we use MESSENGER data to produce the first geological map of this quadrangle at a scale of 1:3,000,000, based on linework completed at a scale of 1:300,000.

Impact crater degradation, Oxia Planum, Mars
Journal of Maps, 2021 The main goal of the European Space Agency (ESA) and Roscosmos ExoMars rover mission is to collect samples from the near-subsurface of Mars. The rover will look for any physical or chemical evidence of ancient life in the near subsurface.

Vision‐based crater and rock detection using a cascade decision forest
IET Computer Vision, 2019 Both crater and rock detection are components of the autonomous landing and hazard avoidance technology (ALHAT) sensor suite, as craters and rocks represent the majority of landing hazards.
