Deciding the point-to-fixed-point problem for skew tent maps on an interval

Journal of computer and system sciences (Print), 2021
We consider a family of skew tent maps f a on the unit interval, determined by the parameter a, with 0 a 1 . We give a decision procedure, that on input a and a point x 0 in the unit interval, determines whether or not the sequence x 0 , f a ( x 0 ) , f ...

The Derivative of the Conjugacy Between Skew Tent Maps

International Journal of Bifurcation and Chaos in Applied Sciences and Engineering, 2018
We consider in this article the properties of topological conjugacy of the tent-like maps [Formula: see text], which are piecewise linear and whose graph consists of straight line segments, extending from [Formula: see text] to [Formula: see text] to ...

ON THE SIGNIFICANCE OF THE TENT MAP

International Journal of Bifurcation and Chaos, 2003
Discrete time dynamical systems generated by the iteration of nonlinear maps provide simple and interesting examples of chaotic systems. But what is the physical principle behind the emergence of these maps? In this note we present an approach to this problem by considering a class, Y, of 2–1 chaotic maps on [0, 1] that are symmetric and have ...

Piecewise skew tent maps and piecewise cubic maps

Proceedings of 2011 International Conference on Computer Science and Network Technology, 2011
Output sequences of both skew tent map and cubic map were not random enough to pass NIST tests. That would influence their applications in the field of communications and information security. To overcome the shortcomings, piecewise skew tent maps and piecewise cubic maps are proposed.

Image encryption using generalized tent map

2013 IEEE 20th International Conference on Electronics, Circuits, and Systems (ICECS), 2013
This paper introduces two generalized tent maps where the conventional map is a special case. Although the output of the conventional tent map shows different responses, it has only one control parameter that limits its behavior and applications. The proposed generalized tent maps increase the degrees of freedom and produce a versatile response that ...

PRNG Based on Skew Tent Map

Arabian Journal for Science and Engineering, 2018
Internet of things (IoT) devices should be designed taking security requirements into consideration, so that they can be used securely in open environments. Designing secure IoT devices requires the ability to design fast and secure cryptography modules.

The Comedian's World: Some Tentative Mappings

Psychological Reports, 1972
To recover the properties serving to define the imaginary worlds evoked by contemporary comedians, word associations—more correctly, comedian associations—were gathered in response to the names of 37 currently recognizable comedians. From these data associative overlap scores were computed between all possible pairs of comedians and a factor analysis ...

Dynamical properties of the tent map

Journal of the London Mathematical Society, 2016
This paper considers the family of tent maps \(T_\alpha:[0,1] \rightarrow [0,1]\) with \(\alpha >1\) whose graphs contain the points \((0,0)\), \((\frac{1}{\alpha},1)\), and \((1,0)\). The aim of the paper is to find \(\alpha\)'s for which \[ {\text{Per}}(T_\alpha)=\mathbb{Q}(\alpha)\cap [0,1], \qquad {\text{(P)}} \] \[ {\text{Fin}}(T_\alpha)=\mathbb{Z}

An Image Cryptosystem based on Tent Map

2020 Third International Conference on Smart Systems and Inventive Technology (ICSSIT), 2020
With the increasing growth of multimedia applications, security has become an important aspect of the transmission of images. Encryption is one form to guarantee safety. Digital images need security in storing and communication and are made use of in numerous domains namely medical systems, audiovisual applications, military etc.
