TL;DR: A relationship between 3D rotation of an object and 2D shape changes in a sequence of images is established and it is shown that with orthographic projections, the3D rotation angles can be computed from a set of linear shape change parameters.

TL;DR: In this paper, it was shown that the tensor surface harmonic (TSH) method for the bonding theory of transition metal clusters is essentially the "orbital character" (OC) scheme proposed by the author and his co-workers.
Abstract: This paper shows that the tensor surface harmonic (TSH) method for the bonding theory of transition metal clusters is essentially the “orbital character” (OC) scheme proposed by the author and his co-workers. It is found, if the surface harmonic function is used as the generator orbital (GO), that the tensor surface harmonic functions can be expressed in terms of the rotation matrix elements D m′m l ( α, β, γ ), and that the weighted energy can be given by a closed formula.

TL;DR: In the space of ℂn there is a well-known integral representation of Bochner-Martinelli as discussed by the authors, which is also known as the integral BochNER-MARTINELLI representation.

TL;DR: The basic principle of this specific digital time correlative accumulation is introduced and the prospects for successful use in an acoustic channel with multipath, time-space variables and high noise level are amply discussed.
Abstract: A specific digital time correlative accumulation has been developed. It is an adaptable scheme of signal processing for underwater acoustic technology used in telemetry., telecontrol and some remote sensing. Its basic principle is here introduced and the prospects for successful use in an acoustic channel with multipath, time-space variables and high noise level are amply discussed. The performances of this scheme are analysed.
