Perhaps one of the most interesting is the one conceived of by the German philologist Theodor Benfey, who created a two dimensional spiral in 1964.
Interestingly, some of these beams could be designed with controllable spatial profiles and thus propagate along various desired trajectories such as parabolic, snake-like, hyperbolic, hyperbolic secant, three-dimensional spiraling, and even self-propelling trajectories.
Both models produced two-dimensional spiral wave dynamics for that were similar for each patient.
Taking the format of a common photograph album, Coffin organized a series of postcards depicting rainbows into a three-dimensional spiral forming one enormous rainbow.
A newly developed three-dimensional spiral injection scheme for beam insertion into a solenoidal storage ring is reported.
An elegant three-dimensional spiral design is carved into the end armrests -- a wave motif that is echoed in seven staircases along the promenade, whose shallow steps are of the same granite as the benches.
The current draft, like last year's version, declares, "The five towers on the master plan shall be organized in a three-dimensional spiral culminating in the Freedom Tower," following the overall design concept by Studio Daniel Libeskind.
Through introducing two piecewise-linear triangular wave functions in a three-dimensional spiral chaotic Colpitts oscillator model, a four-dimensional grid multiscroll hyperchaotic system is constructed.
The purpose of this study was to determine the precision and accuracy of 3-dimensional spiral computed tomography-based linear measurements of neoplasms associated with the mandible.
Its cladding, made of perforated steel plates, forms an intricate three-dimensional spiral characterized by five different diameters which decrease along the height of the structure.
Axisymmetric, basic spherical Couette flow computations are compared with available numerical results while a three-dimensional spiral Taylor-Görtler vortex flow simulation is tested against experimental measurements.
