We calculate the distance between the objects and check that the distance is not less than the acceptable minimum for the calculation: var distance = math.distance(position, Transforms[i].Position); var permittedDistance = math.max(distance, MinDistance); We calculate the gravitational force from...
example. calculating specific gravity specific gravity is determined by dividing the density of a material by the density of water at 4 degrees celsius. for the calculation, the density of the material and that of the water must be expressed in the same units. density of water in various ...
superstring theory and its superset M-Theory can be satisfied by extra number systems, such as the hypercomplex quaternion and octonion numbers. Mathematician Cohl Furey has shown that quaternions can represent the charge of quarks and leptons in the standard model. See:https://www.youtube.com/...
Hi all, I am trying to model the gravitation field due disturbances of density. I am using the Poisson's equation for gravity e.g.en.wikipedia.org/wiki/Poisson's_equation Let's consider a cube with 1x1x1 meter as geometry. Now starting comsol, I use the Poisson module, where I assign...
example gtotal = gravitywgs84(h,lat,lon,'Exact',[noatm,nocent,prec,jd],action) calculates an array of total gravity values in the direction normal to the Earth surface at point P in the direction normal to an ellipsoid confocal to the Earth WGS84 ellipsoid passing through point P. exampl...

Pipe vibration can be used to insert a long optical fibre into a long spatially curved, e.g. helical, steel pipe (Longet al.1993,1994). The optical fibre may be viewed as a ‘plug-flow’ model of a flowing fluid as in Bourrière's work (Sections 3.1and5.2.8). However,Jensen (1997...
The calculation formulas for drilling energy variables are discussed in this section. First, as a dynamic energy system, the drill string takes energy inputs from surface devices (top drive and draw works), gravity potential energy, and a mud motor deployed downhole.The work (energy input) done...
