and Introduction: A synthesis of a diverse suite of observations of H2O-related landforms that are possible Mars analogs from terrestrial polar regions (Devon Island in the Arctic; the Dry Va lleys of Antarctica) put into question any requirement for extended episode(s) of warm and wet climate in Mars’s past. Geologically transient episodes of localized H2O cycling, forced by exogenic impacts, ...

Mechanisms of creating fractals have been clarified in various fields of science [1-3]. A remarkable success may be the discovery of so-called Laplacian fractals which involve pattern formations in diffusion-limited ag gregation, viscous fingering, crystallization, electrodeposition, dielectric breakdown, chemical dissolution, and bac terial colony growth. Fractal geometry is especially powerfu...

The vegetation type and its coverage in forest ecosystems are crucial soil erosion surface runoff. Cover crops provide significant protection to the aggregates, preventing damage caused by rainfall runoff that might occur absence of these crops. However, changes land use, such as converting forests into oil palm plantations, have resulted cover, which affect erosion, runoff, and, ultimately, ec...

Leading edge protection (LEP) coating systems are applied to protect turbine blade edges from rain erosion. The performance of a LEP system is assessed in an accelerated erosion test (RET) as metric for industrial application, but these tests expensive. Modelling methods available predict erosion, based on fundamental material properties, there lack validation. Springer model (1976) analysed th...

Controlled traffic farming (CTF) is used to confine soil compaction the least possible area of field, thereby achieving economic and environmental benefits. In context climate change, erosion one most discussed topics, there a research gap in understanding effects CTF on Central Europe. The aim this work was show potential reduce water erosion, terms runoff loss steep land. A 16 ha experimental...

— This paper introduces a new rain removal model based on the shrinkage of the sparse codes for a single image. Recently, dictionary learning and sparse coding have been widely used for image restoration problems. These methods can also be applied to the rain removal by learning two types of rain and non-rain dictionaries and forcing the sparse codes of the rain dictionary to be zero vectors. H...
