Toeplitz Operator and Carleson Measure on Weighted Bloch Spaces

open access: yesJournal of Function Spaces, 2019
In this paper, we consider Toeplitz operator acting on weighted Bloch spaces. Meanwhile, the inclusion map from weighted Bloch spaces into tent space is also investigated.

Bifurcation Structures in a Bimodal Piecewise Linear Map

open access: yesFrontiers in Applied Mathematics and Statistics, 2017
In this paper we present an overview of the results concerning dynamics of a piecewise linear bimodal map. The organizing principles of the bifurcation structures in both regular and chaotic domains of the parameter space of the map are discussed.

Collaborative Target Search Algorithm for UAV Based on Chaotic Disturbance Pigeon-Inspired Optimization

open access: yesApplied Sciences, 2021
Unmanned aerial vehicles (UAVs) have shown their superiority in military and civilian missions. In the face of complex tasks, many UAVs are usually needed to cooperate with each other. Therefore, multi-UAV cooperative target search has attracted more and

Bubble Formation Control: Fabrication of Centimeter‐Sized Tissue‐Like Constructs by Catalase‐Coated Oxygen‐Releasing Hydrogel

open access: yesAdvanced Materials, EarlyView.
Oxygen‐releasing hydrogels are widely used to support cell survival in 3D cultures and to promote wound healing. However, incorporating catalase to convert H2O2 into O2 often generates additional oxygen bubbles, leading to material instability which rarely addressed.

A CMOS Implementation of the Tent Map for Random Number Generation

open access: yes2021 IEEE 12th Latin America Symposium on Circuits and System (LASCAS), 2021
A new tent map based random number generator (RNG) is designed in TSMC 65 nm CMOS technology. Simulation results verify that the generated random sequences successfully pass the randomness tests in the FIPS-140-2 and NIST 800–22 test suites. Superior to other studies in the literature, our RNG satisfies the randomness tests without post processing ...

The Digital Tent Map: Performance Analysis and Optimized Design as a Source of Pseudo-Random Bits [PDF]

open access: yes, 2004
In this paper, a digital implementation of the Tent map is analyzed as a source of pseudo-random bits. In particular, several solutions are investigated, taking into account the numerical errors due to the approximation strategy used (truncation/rounding

Cryptanalyzing and Improving a Novel Color Image Encryption Algorithm Using RT-Enhanced Chaotic Tent Maps

open access: yesIEEE Access, 2018
In recent years, chaos-based image encryption algorithms have aroused extensive research interest. However, some image encryption algorithms still have several security defects, and the research on cryptanalysis is relatively inadequate.
