The phrase "a spherical design" is correct and usable in written English.
It can be used when describing an object, concept, or structure that has a round or globe-like shape.
Example: "The architect presented a proposal featuring a spherical design for the new community center, emphasizing its modern aesthetic."
Alternatives: "a round design" or "a globe-like design".
Also we investigate whether there is a spherical design of harmonic index attaining the bound.
These definitions are of a different nature, illustrating the broadness of the concept of a spherical design.
In this paper, we define a spherical design of harmonic index t from the viewpoint of this equivalent condition, and we give its construction and a Fisher type lower bound on the cardinality.
BBD is a spherical design with excellent predictability within the spherical design space.
The mirror for the proposed telescope has a novel spherical design that will allow it to be enlarged, or built in stages, said Dr. Guy Monnet, an astronomer at the European Southern Observatory and the project manager for OWL.
Thus, two dome-shaped skeletons represent halves of a more spherical design, which suggests that the role of the silicoflagellate basal ring is to enable double skeleton formation, but the full implications of this have yet to be explored.
By means of a computer search, Hardin and Sloane (1996) found spherical designs for all t 13 with a minimal number of points; for instance, they produced a (94, 13 -design.
Best results were achieved with a 400 500 nm spherical design with alternating surface coatings of catalase and PSS over a silica core.
The reward using of Box-Behnken designs to include the fact that they are all spherical designs and require factors to be run at only three levels.
It is well-known that an equivalent condition of spherical design is given in terms of harmonic polynomials.
As a generalization of these results, we prove that a union of spherical designs with a certain property carries the structure of a coherent configuration.
