This manuscript presents Hyers-Ulam stability and Hyers--Ulam--Rassias stability results of non-linear Volterra integro--delay dynamic system on time scales with fractional integrable impulses. Picard fixed point theorem  is used for obtaining  existence and uniqueness of solutions. By means of   abstract Gr"{o}nwall lemma, Gr"{o}nwall's inequality on time scales, we establish  Hyers-Ulam stabi...

conclusions the delay time from symptom onset to hospital admission was high in patients with ami. it is necessary to create emergency medical system (ems) stations in suburbs and train the public on the importance of quick contact with the ems when the symptoms of an ami are observed. results the median delay was 129 minutes (mean ± sd, 240.44 ± 295.30). overall, 32.5% of patients were admitte...

In this paper, a decentralized adaptive neural controller is proposed for a class of large-scale nonlinear systems with unknown nonlinear, non-affine subsystems and unknown nonlinear time-delay interconnections. The stability of the closed loop system is guaranteed through Lyapunov-Krasovskii stability analysis. Simulation results are provided to show the effectiveness of the proposed approache...

This article proposes a direct method for solving three types of integral equations with time delay. By using operational matrix of integration, integral equations can be reduced to a linear lower triangular system which can be directly solved by forward substitution. Numerical examples shows that the proposed scheme have a suitable degree of accuracy.  

using a hierarchical hybrid fuzzy model, this paper presents an intelligent system to manage the traffic of ambulances and the vehicles for transporting blood and blood products and generally the transportation related to health emergencies. the transportation of emergency patients, emergency accidents and health-related emergencies, and the transportation of blood and blood products should be ...

determination of pre-hospital delay time of patients with acute myocardial infarction and seeking ways of speeding up the time for reperfusion is an important factor to lower mortality in these patients. this is a cross-sectional study to determine pre-hospital delay time, its components, and related causes and conditions, obtained in 375 patients with prolonged chest pain referred to four hosp...
