Formal deformation of curves with group scheme action [PDF]
, 2004 We study equivariant deformations of singular curves with an action of a finite flat group scheme, using a simplified version of Illusie's equivariant cotangent complex.

Development of Saudi continuous chart datum: Arabian Gulf case study
Geomatics, Natural Hazards & Risk, 2019 Global navigation satellite systems (GNSS) is widely utilized in marine applications for high accuracy vertical positioning. The errors introduced to charts by the present use of traditional shore-based discrete point chart datum (CD) can become a ...

Measuring the Water Level Datum Relative to the Ellipsoid During Hydrographic Survey [PDF]
, 2011 Hydrographic surveys are referenced vertically to a local water level “chart” datum. Conducting a survey relative to the ellipsoid dictates a datum transformation take place before the survey is used for current navigational products.

Vertical datum and coordinate systems in Jordan
International Journal of Information Technology, Communications and Convergence, 2011 Advancement in satellites and telecommunication technologies has created a great interest in global positioning system (GPS) applications. The lack of a good geoid model for Jordan has limited the use of GPS applications. This has lead to refining the Jordanian geoid model for better GPS measurements in order to obtain reliable results in the triplet ...

The Anatomical Record, EarlyView.Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Enhancement of height system for Malaysia using space technology: the study of the datum bias inconsistencies in Peninsular Malaysia [PDF]
, 2003 The algorithm for orthometric height transfer using GPS has been widely presented. Its practical limitations are mostly due to datum bias inconsistencies and lack of precise geoid.

Biogeography of intertidal invertebrates is influenced by latitude along the west coast of Australia
Ecography, EarlyView.Along the west coast of Australia, intertidal rock platforms support high invertebrate diversities that provide vital ecosystem services, yet patterns in diversity are not well understood. Here, we document and examine the invertebrate assemblages on intertidal rock platforms in Western Australia and delineate ecoregions according to assemblage ...

Journal of Quaternary Science, EarlyView.ABSTRACT The second half of the Allerød interstadial in the Netherlands is characterised by pine forest. Excavated trunks of 165 pine trees at Leusden‐Den Treek in the central Netherlands (LETR16) were dated by dendrochronology and radiocarbon. Two chronologically separated pine forest phases occurred during relatively warm periods as recorded in ...
