Multipole structure and coordinate systems
Multipole expansions depend on the coordinate system, so that coefficients of multipole moments can be set equal to zero by an appropriate choice of coordinates. Therefore, it is meaningless to say that a physical system has a nonvanishing quadrupole moment, say, without specifying which coordinate system is used. (Except if this moment is the lowest non-vanishing one.) This result is demonstra...

متن کاملSynthesis and Crystal Structure of a Novel Six-Coordinate Gallium (III) Complex
The reaction of gallium (III) nitrate octahydrate with the proton transfer compound (pydaH2)2+ (pydc)2– ( where pyda is 2,6-pyridinediamine and pydcH2 is 2,6-pyridinedicarboxylic acid) leads to the formation of (C5H8N3) [Ga(C7H3NO4)2] · 4H2O · CH3OH. The crystal system of the anionic complex is triclinic with space group Pī and two molecules per unit cell. The unit cell parameters are a=10.23...
متن کاملCoordinate Systems and Terrain Reusability
This paper is about a coordinate system problem for the “live” aspect of LVC training that impacts terrain reusability. Commonly used commercial software for producing correlated terrains has an outdated definition of datums that assumes that NAD83 and WGS84 are still equivalent, and does not take into account the newer realizations of these, or the fact that there have been significant plate t...
متن کاملInteroperable Coordinate Transformation and Identification of Coordinate Systems
The OpenGIS Consortium (OGC), an industry group, has developed COM, CORBA and Java interface specifications allowing vendors to develop mutually interoperable geospatial software. OGC established the Coordinate Transformation Working Group (CT-WG) in April 1998. The working group developed a Unified Modeling Language object model of coordinate systems (CS) and coordinate transformations (CT) in...
