Construction of Mutually Orthogonal Graph Squares Using Novel Product Techniques

open access: yes, 2022
Sets of mutually orthogonal Latin squares prescribe the order in which to apply different treatments in designing an experiment to permit effective statistical analysis of results, they encode the incidence structure of finite geometries, they ...

A Direct Construction of Inter-Group Complementary Code Set

open access: yesIEEE Access, 2018
Complete complementary codes (CCCs) is a collection of mutually orthogonal complementary codes and Inter-group complementary (IGC) code set consists of multiple disjoint groups of 2-D codes.

Daily scale wintertime sea surface temperature and IPC-Navidad variability in the southern Bay of Biscay from 1981 to 2010 [PDF]

open access: yesOcean Science, 2013
The combination of remotely sensed gappy Sea surface temperature (SST) images with the missing data filling DINEOF (data interpolating empirical orthogonal functions) technique, followed by a principal component analysis of the reconstructed data, has ...

On the othogonal trajectories and conformal mapping of complex variable functions [PDF]

open access: yes, 2015
This research goal is to investigate the connection of orthogonal trajectories, analitic functions, and conformal mapping. Orthogonal trajectories are the intersection of two families of mutually perpendicular curves. The analytical property of a complex

Nonspectrality of Certain Self-Affine Measures on ℝ3

open access: yesAbstract and Applied Analysis, 2014
We will determine the nonspectrality of self-affine measure μB,D corresponding to B=diag[p1,p2,p3]  (p1∈(2ℤ+1)∖{±1}, p2∈2ℤ∖{0}), and D={0,e1,e2,e3} in the space ℝ3 is supported on T(B,D), where e1,  e2, and e3 are the standard basis of unit column ...

A COMPARATIVE ANALYSIS OF RADIATION FROM CIRCULAR AND RECTANGULAR APERTURES: LIMITATIONS ON THEIR USE FOR BESSEL BEAM FORMATION [PDF]

open access: yesRadio Physics and Radio Astronomy
Subject and Purpose. Essentials of the processes for millimeter-wavelength radiation from circular apertures are analyzed, with emphasis on the formation of the field’s radiation pattern (RP) and modal structure in the aperture.

A Rigid-Foldable Kirigami-Inspired Metamorphic Mechanism With Programmable Motion Modes and Self-Locking. [PDF]

open access: yesAdv Sci (Weinh)
Geometric constraint reconfiguration enables a rigid–foldable kirigami‐inspired mechanism to switch between twisting, directional translation, and self‐locking states. By encoding multifunctionality directly into its architecture, the mechanism achieves multimodal motion and passive locking without reassembly, providing a compact platform for adaptive ...

Mutually consistent magnetic charts based on orthogonal functions

open access: yesJournal of Geophysical Research, 1964
A method is developed for expanding a set of observations of the horizontal vector of the earth's magnetic field in a set of orthogonal polynomials, each of which is curl free. The final result is a pair of simple polynomials, one each for X and Y, such that the radial component of the curl of the predicted geomagnetic field vanishes identically.
