Users, Engineers, Surveyors, and GIS Professionals spend an enormous amount of time correcting field surveys to the classical State Plane Coordinate System (SPCS). The current mapping corrections are in the order of 1:30,000, or 33 parts per million (ppm). Modern surveys (e.g., GPS/In...
"In mid-November, I directed the New York State Intelligence Center to actively investigate drone sightings and coordinate with federal law enforcement to address this issue, and those efforts are ongoing. But in order to allow state law enforcement to work on this issue, I am now calling on ...
In general, we do not expect unique factorisation in this coordinate ring (this is basically because Bezout’s theorem suggests that the zero set of a polynomial on will almost never consist of a single (closed) point). Of course, we can use the algebraic formalism of ideals to get around...
The \(yoz\) plane of the Cartesian coordinate system is parallel to the [111] planes of the tungsten crystal. Quasi-parallel proton beam of kinetic energy \(E_k=2\)MeV was assumed to be aligned with the \(z\)-axis of the coordinate system, and let \(k_z\) be a longitudinal ...
The method reduces the orbit determination process to performing intersections of two-dimensional laminas in the plane. Sciré et al. showed that the batch estimators could be a useful tool to estimate the state of space debris at a certain time [24]. Tao et al. presented a more accurate ...
Some coordinate system names were changed. Corrections were made to transformation methods for some coordinate systems. Some outdated transformation WKIDs were removed that no longer exist in the EPSG registry. The transformations are still supported with their current WKIDs. New vertical transformations...
This seems like an inherently modularizable and repetitive task, which could particularly benefit from both crowdsourcing and automated tools, if given the right platform to rigorously coordinate all the contributions; and it is a type of mathematics that previous methods usually could not scale up ...
Thus, the study’s simulation model was established using a 2D plane coordinate system. According to geometry information of the field-testing sections of cutting on MJ-HSR, Detailed dimensions for the cutting calculation model as follows: the depth of the cutting is approximately 8.0 m, and ...
The X axis completes the right-handed coordinate system; the +X direction is always oriented towards the Sun for GPS BLOCKII/IIA, IIF, BeiDou and GLONASS-M satellites and away from the Sun for GPS BLOCKIIR satellites. The nominal attitude of a GPS satellite should satisfy two ...
A basis of this space generates a coordinate matrix of full rank, which implies that there is at least one non-singular minor. This implies that there exists a function in this space which is nowhere vanishing on some subset of of cardinality at least . If we multiply (3) by and sum ...
