Design of integrated radar and communication system based on solvable chaotic signal [PDF]
Scientific ReportsIn the integrated radar and communication system (IRCS), the design of signal that can simultaneously satisfy the radar detection and communication transmission is very important and difficult. Recently, some new properties of a class of solvable chaotic

Blind Frequency Estimation and Symbol Recovery for the Analytically Solvable Chaotic System
Entropy, 2019 The analytically solvable chaotic system (ASCS) is a promising chaotic system in chaos communication and radar fields. In this paper, we propose a maximum likelihood estimator (MLE) to estimate the frequency of ASCS, then a difference-integral (DI ...

Conserved charges of series of solvable lattice models
Nuclear Physics BAn infinite number of solvable Hamiltonians, including the transverse Ising chain, the XY chain with an external field, the cluster model with next-nearest-neighbor x-x interactions, or with next-nearest-neighbor z-z interactions, and other solvable ...

Solvability of System of Neutrosophic Soft Linear Equations [PDF]
Neutrosophic Sets and Systems, 2021 This article exposes a system of Neutrosophic Soft Linear Equations (NSLE) of the form A ⊗ x = b and is said to be solvable if A ⊗ x(A; b) = b holds, otherwise unsolvable.

Profinite just infinite residually solvable Lie algebras [PDF]
International Journal of Group Theory, 2023 We provide some characterization theorems about just infinite profinite residually solvable Lie algebras, similarly to what C. Reid has done for just infinite profinite groups.

Explicitly solvable systems of two autonomous first-order Ordinary Differential Equations with homogeneous quadratic right-hand sides [PDF]
Open Communications in Nonlinear Mathematical Physics, 2021 After tersely reviewing the various meanings that can be given to the property of a system of nonlinear ODEs to be solvable, we identify a special case of the system of two first-order ODEs with homogeneous quadratic right-hand sides which is explicitly ...

New Solvable System of 2 First-Order Nonlinearly-Coupled Ordinary Differential Equations [PDF]
Open Communications in Nonlinear Mathematical Physics, 2022 In this short communication we introduce a rather simple autonomous system of 2 nonlinearly-coupled first-order Ordinary Differential Equations (ODEs), whose initial-values problem is explicitly solvable by algebraic operations.

Exact solvability of superintegrable systems [PDF]
Journal of Mathematical Physics, 2001 It is shown that all four superintegrable quantum systems on the Euclidean plane possess the same underlying hidden algebra sl(3). The gauge-rotated Hamiltonians, as well as their integrals of motion, once rewritten in appropriate coordinates, preserve a flag of polynomials.

Signals, 2023 We present an algorithm for extracting basis functions from the chaotic Lorenz system along with timing and bit-sequence statistics. Previous work focused on modifying Lorenz waveforms and extracting the basis function of a single state variable ...

Solvability = Typability + Inhabitation [PDF]
Logical Methods in Computer Science, 2021 We extend the classical notion of solvability to a lambda-calculus equipped with pattern matching. We prove that solvability can be characterized by means of typability and inhabitation in an intersection type system P based on non-idempotent types.
