A Novel Image Compression-Encryption Scheme Based on Chaos and Compression Sensing
In this paper, a novel image compression–encryption hybrid algorithm is proposed. First, a Gauss random matrix and a random scrambling matrix are generated by using Chebyshev mapping and Logistic mapping, respectively. Then, based on the principle

One-Dimensional MUSIC-Type Algorithm for Spherical Microphone Arrays
Spherical microphone arrays have been widely used in direction-of-arrival (DOA) estimation in recent years. The conventional multiple signal classification method formulated in spherical harmonic domain (SHMUSIC) is computationally expensive ...

Deviations of the Lepton Mapping Matrix from the Harrison-Perkins-Scott Form
We propose a simple set of hypotheses governing the deviations of the leptonic mapping matrix from the Harrison-Perkins-Scott (HPS) form. These deviations are supposed to arise entirely from a perturbation of the mass matrix in the charged lepton sector.

Models of q-algebra representations: Matrix elements of the q-oscillator algebra [PDF]
This article continues a study of function space models of irreducible representations of q analogs of Lie enveloping algebras, motivated by recurrence relations satisfied by q-hypergeometric functions.

In order to reveal quantitative trait loci (QTL) interactions and the relationship between various interactions in complex traits, we have developed a new QTL mapping approach, named genotype matrix mapping (GMM), which searches for QTL interactions in ...

Vertical Accuracy Simulation of Stereo Mapping Using a Small Matrix Charge-Coupled Device
At present, without ground control points (GCPs), the positioning accuracy of remote sensing images often fails to meet the growing requirements for mapping accuracy. Multi-load synergy to improve accuracy without GCPs by eliminating the impact of stereo

Matrix factorizations and pentagon maps
We propose a specific class of matrices that participate in factorization problems that turn out to be equivalent to constant and entwining (non-constant) pentagon, reverse-pentagon or Yang–Baxter maps, expressed in non-commutative variables. In detail, we show that factorizations of order N

Topology optimization of three-translational degree-of-freedom spatial compliant mechanism
Considering that the Jacobian matrix maps the velocity of the joint space of the robot to the end velocity of the Cartesian space, a novel topology optimization approach is proposed in this article for the design of three-translational degree-of-freedom ...
