Suppression and synchronization of chaos in uncertain time-delay physical system

引用

Applied Mathematics:A Journal of Chinese Universities 2024年第3期39卷 416-437页

作者： Israr Ahmad muhammad Shafiq Department of Preparatory Studies Centre University of Technology and Applied Sciences Department of Electrical and Computer Engineering Sultan Qaboos University

The mechanical horizontal platform (MHP) system exhibits a rich chaotic *** chaotic MHP system has applications in the earthquake and offshore industries. This article proposes a robust adaptive continuous control (RACC) algorithm. It investigates the control and synchronization of chaos in the uncertain MHP system with time-delay in the presence of unknown state-dependent and time-dependent disturbances. The closed-loop system contains most of the nonlinear terms that enhance the complexity of the dynamical system; it improves the efficiency of the closed-loop. The proposed RACC approach (a) accomplishes faster convergence of the perturbed state variables (synchronization errors) to the desired steady-state,(b) eradicates the effect of unknown state-dependent and time-dependent disturbances, and (c)suppresses undesirable chattering in the feedback control inputs. This paper describes a detailed closed-loop stability analysis based on the Lyapunov-Krasovskii functional theory and Lyapunov stability technique. It provides parameter adaptation laws that confirm the convergence of the uncertain parameters to some constant values. The computer simulation results endorse the theoretical findings and provide a comparative performance.

Cervical cancer is an intrusive cancer that imitates various women around the world. Cervical cancer ranks in thefourth position because of the leading death cause in its premature stages. The cervix which is the lower end of thevagina that connects the uterus and vagina forms a cancerous tumor very slowly. This pre-mature cancerous tumorin the cervix is deadly if it cannot be detected in the early stages. So, in this delineated study, the proposed approachuses federated machine learning with numerous machine learning solvers for the prediction of cervical cancer totrain the weights with varying neurons empowered fuzzed techniques to align the neurons, Internet of MedicalThings (IoMT) to fetch data and blockchain technology for data privacy and models protection from hazardousattacks. The proposed approach achieves the highest cervical cancer prediction accuracy of 99.26% and a 0.74%misprediction rate. So, the proposed approach shows the best prediction results of cervical cancer in its early stageswith the help of patient clinical records, and all medical professionals will get beneficial diagnosing approachesfrom this study and detect cervical cancer in its early stages which reduce the overall death ratio of women due tocervical cancer.

Evolution of light deflection and shadow from a gauge-potential-like AdS black hole under the influence of a non-magnetic plasma medium

引用

Communications in Theoretical Physics 2024年第9期76卷 85-96页

作者： Riasat Ali Xia Tiecheng muhammad Awais Rimsha Babar Department of Mathematics Shanghai University and Newtouch Center for Mathematics of Shanghai University Department of Mathematics University of Engineering and Technology Department of Mathematics GC University Faisalabad Layyah Campus

We investigate the light deflection in the weak field approximation from the accelerating charged AdS black hole. For this purpose, we apply the Gauss–Bonnet theorem to calculate the light deflection in the weak field area and use the Gibbons–Werner approach to analyze the optical geometry of the accelerating charged AdS black hole in the non-magnetic plasma absence/presence of a non-magnetic medium. We also represent the graphical behavior of the light deflection angle w.r.t. the impact parameter. We also compute the light deflection angle using Keeton and Petters approximations under the impact of accelerating charged AdS black hole geometry. Furthermore, by using the ray-tracing approach, we determine the shadow in the nonmagnetic plasma presence and also demonstrate that graphical shadow has an impact on the gauge potential, non-magnetic plasma frequencies and charge.
