The knowledge of Arctic Sea ice coverage is particular importance in studies climate change. This study develops a new sea classification approach based on machine learning (ML) classifiers through analyzing spaceborne GNSS-R features derived from the TechDemoSat-1 (TDS-1) data collected over open water (OW), first-year (FYI), and multi-year (MYI). A total eight extracted observables five month...

Motion of uid elements can be described by the Navier-Stokes equations. They arise from use Law motion to a uid. In this investigation, two dimensional have been engaged. Then they are applied an incompressible viscous movement down inclined plane with net ow. These leads examining effects velocity at various angles inclination and finding boundary layer thickness. Viscous laminar fluid ow also...

Abstract Ongoing global changes are expected to affect the worldwide production of many fisheries and aquaculture systems. Because invertebrates represent a relevant industry, it is crucial anticipate challenges that resulting from current environmental alterations. In this review, we rely on estimated physiological limits six commercialised species sea urchins ( Loxechinus albus , Mesocentrotu...

Conventional work ow functionality like task sequencing, split parallelism, join synchronisation and iteration have proven e ective for business process automation and have widespread support in current work ow products. One the other hand, newer requirements for work ows are encountered in practice, opening grave uncertainties about the extensions for current languages. Di erent concepts, alth...

The mol-ecule of the title compound C7H8N4O·0.5H2O, alternatively called (E)-1-(pyridin-4-yl-methyl-ene)semi-carb-azide hemihydrate, is in the E conformation and is almost planar; the r.m.s. deviation of the positions of the atoms of the pyridine ring from the best-fit plane is 0.0039 Å. The C, N and O atoms of the rest of the mol-ecule sits close on this plane with a largest deviation of 0.115...

In the title compound, C(4)H(6)N(3) (+)·H(2)O(4)P(-)·H(2)O, the pyrimidin-ium ring is essentially planar, with an r.m.s. deviation of 0.0016 Å. In the structure, pairs of symmetry-related anions are connected into centrosymmetric clusters via strong O-H⋯O hydrogen bonds forming six-membered rings with an R(2) (2)(6) motif. These clusters are inter-connected via water mol-ecules through OW-H⋯O h...

Abstract Combining spatially localized X-ray diffraction (XRD) with microtomography (XMT) enables the mapping of micro- and nanoscale structures simultaneously. The combination these methods results in a powerful tool when considering structural studies hierarchical materials, allowing one to couple relationships connections at various scales. In this study, XMT was used map anatomy cellular 3D...
