Cartesian Coordinates (x,y,z) Cylindrical Coordinates (r,q,z) Spherical Coordinates (r,q,f) Vectors In 1 dimension, we can specify direction with a + or - sign. In 2 or 3 dimensions, we need more than a sign to specify the direction of something: ...
An ultrasound imaging system includes a scan conversion process for converting ultrasound data into a standard display format conversion and can be performed on a personal computer by programming the computer to convert data from polar coordinates to Cartesian coordinates suitable for display on a comput...
The solutions in Cartesian coordinates are the Hermite–Gaussian modes, which are given by (4) HGm,n(˜x,˜y)=NmnwHm(˜x)Hn(˜y)e−˜x2+˜y22e−iΦN,˜x=√2x/w,˜y=√2y/w,HGm,n(x̃,ỹ)=NmnwHmx̃Hnỹe−x̃2+ỹ22e−iΦN,x̃=2x/w,y...
These transducer arrays acquire three-dimensional data in spherical coordinates along lines tiled in azimuth and elevation angles at incremental depth. This study aims at evaluating fast filtering and scan conversion algorithms applied in the spherical domain prior to visualization into Cartesian coordinates...
For molecular structures with very low symmetry, the hyperpolarizability tensor could be estimated more accurately by using the mixed spherical-Cartesian formalism [42]. In this formalism, the orientational averaged first-order hyperpolarizability squared ⟨βHRS⟩ is expressed by Equation (4), in...
Based on the obtained amplitudes of the electric field vector projections in the focus (2), it is possible to derivate expressions for the intensity and its components along the Cartesian axes. It should be noted that the expressions for the intensity with even and odd numbers m will be diffe...
The Discrete Ordinates Model (DOM) solves the radiative transfer equation (RTE) for a finite number of discrete solid angles, each associated with a vector direction si (i = 1, 2, . . . , n) fixed in the global Cartesian system, and the integrals over these directions are replaced by...
