A Blockchain-Based Traceable IP Copyright Protection Algorithm

IEEE Access, 2020
Current Intellectual Property (IP) copyright protection technologies have low efficiency of authority management, traceability, and scalability. In this work, a blockchain-based IP copyright protection algorithm is proposed to address these issues by ...

The logarithmic link between the solvable population growth mapping and the quadratic mapping

, 1984
The concept of functional logarithm permits to establish an exact relation between the quadratic mapping and the so-called population growth mapping whose iterations are analytically known.

Dynamics of non-classical interval exchanges [PDF]

, 2010
A natural generalization of interval exchange maps are linear involutions, first introduced by Danthony and Nogueira [Measured foliations on non-orientable surfaces. Ann. Sci. Éc. Norm. Supér. (4) 26(6) (1993), 645–664].

Hyers–Ulam stability and hyperstability of a Jensen-type functional equation on 2-Banach spaces

Journal of Inequalities and Applications, 2022
The main aim of this paper is to establish the Hyers–Ulam stability and hyperstability of a Jensen-type quadratic mapping in 2-Banach spaces. That is, we prove the various types of Hyers–Ulam stability and hyperstability of the Jensen-type quadratic ...

General Construction Method and Proof for a Class of Quadratic Chaotic Mappings

Mathematics
The importance of chaotic systems as the main pseudo-random cryptographic generator of encryption algorithms in the field of communication secrecy cannot be overstated, but in practical applications, researchers often choose to build upon traditional ...

Approximate Quartic and Quadratic Mappings in Quasi-Banach Spaces

International Journal of Mathematics and Mathematical Sciences, 2011
we establish the general solution for a mixed type functional equation of aquartic and a quadratic mapping in linear spaces. In addition, we investigate the generalized Hyers-Ulam stability in p-Banach spaces.

On multidimensional BICM-ID constellation labelling [PDF]

, 2010
It is widely recognised that the choice of a specific bit-to-symbol mapping scheme or a beneficial constellation labelling is an influential factor, when designing bit-inter-leaved coded modulation using iterative decoding (BICM-ID) for the sake of ...

A General System of Functional Equations Deriving From Additive, Quadratic, Cubic, and Quartic Mappings

Journal of Mathematics
In the current study, we introduce a system of functional equations (FEs) deriving from the mixed type additive–quadratic and the mixed-type cubic–quartic FEs which describes a multimixed additive–quadratic–cubic–quartic mapping.

Linear quadratic control using reinforcement learning and quadratic neural networks [PDF]

, 2023
This thesis focuses on the application of reinforcement learning (RL) techniques to design optimal controllers and observers for linear time-invariant (LTI) systems, namely linear quadratic regulator (LQR), linear quadratic tracker (LQT), and linear ...
