This study focuses on the casualty-load distribution problem that arises when a mass casualty incident(MCI)necessitates the engagement of multiple medical *** discrete event simulations,the study analyzed different MCI response regimes in Lahore,Pakistan,that vary in terms of the level of casualty-load distribution and the required coordination between the incident site and the responding *** terrorist attacks in this major metropolitan area were considered to set up experiments for comparing delays in treatment under the modeled *** analysis highlights that the number of casualties that are allowed to queue up at the nearest hospital before diverting the casualty traffic to an alternate hospital can be an important factor in reducing the overall treatment *** diverting the casualty traffic from the incident site to an alternate hospital can increase the travel time,while a delay in diversion can overload the nearest hospital,which can lead to overall longer waiting times in the *** casualty distribution mechanisms based only on the responding hospitals’available capacity and current load can perform inefficiently because they overlook the trade-off between the times casualties spend in traveling and in queues.

Structural and optical properties of Zn1-xNixTe thin films prepared by electron beam evaporation technique

引用

Progress in Natural Science:Materials International 2015年第1期25卷 22-28页

作者： Arshad Mahmood R. Rashid U. Aziz A. shah Zahid ali Qaiser raza Tanveer Ashraf Nano Devices Laboratories National Institute of Lasers and Optronics (NILOP) P.O. Nilore Islamabad Pakistan

Zn1-xNixTe thin films with different composition(x=0.0, 0.05, 0.10, 0.15 and 0.20) were deposited on glass substrate by electron beam evaporation technique followed by its characterization using advanced structural and optical analysis techniques. Structural properties of the prepared thin films were studied by X-ray diffraction(XRD). The XRD patterns revealed that the binary compounds transformed into a ternary compound with cubic structure having preferred orientation along the c-direction with(111) planes. Composition analysis of the films was determined by energy dispersive analysis of X-rays(EDAX) and found to be in agreement with the precursor composition. Optical properties such as extinction coefficient(k) and band gap energy of these films were examined by using a spectroscopic ellipsometer. It was found that the extinction coefficient(k) increased with the addition of Ni content in the alloy. In comparison, the band gap energy was also determined by using transmission spectra and found to be agreed with that of the ellipsometric results. These analyses confirm that the band gap energy decreases with the increase of Ni content in the alloy.

Robust H_∞ control for uncertain Markovian jump systems with mixed delays

引用

Chinese Physics B 2016年第7期25卷 108-113页

作者： R Saravanakumar M syed ali Department of Mathematics Thiruvalluvar University

We scrutinize the problem of robust H∞control for a class of Markovian jump uncertain systems with interval timevarying and distributed delays. The Markovian jumping parameters are modeled as a continuous-time finite-state Markov chain. The main aim is to design a delay-dependent robust H∞control synthesis which ensures the mean-square asymptotic stability of the equilibrium point. By constructing a suitable Lyapunov–Krasovskii functional（LKF）, sufficient conditions for delay-dependent robust H∞control criteria are obtained in terms of linear matrix inequalities（LMIs）. The advantage of the proposed method is illustrated by numerical examples. The results are also compared with the existing results to show the less conservativeness.

Modeling transmission dynamics of Ebola virus disease

引用

International Journal of Biomathematics 2017年第4期10卷 297-331页

作者： Mudassar Imran Adnan Khan ali R. Ansari syed Touqeer Hussain shah International Center for Applied Mathematics and Computational Bioengineering Department of Mathematics and Natural Sciences Gulf University for Science and Technology Hawally Kuwait Department of Mathematics Lahore University of Management Sciences Lahore Pakistan

Ebola virus disease （EVD） has emerged as a rapidly spreading potentially fatal disease. Several studies have been performed recently to investigate the dynamics of EVD. In this paper, we study the transmission dynamics of EVD by formulating an SEIR-type transmission model that includes isolated individuals as well as dead individuals that are not yet buried. Dynamical systems analysis of the model is performed, and it is consequently shown that the disease-free steady state is globally asymptotically stable when the basic reproduction number, R0 is less than unity. It is also shown that there exists a unique endemic equilibrium when R0 〉 1. Using optimal control theory, we propose control strategies, which will help to eliminate the Ebola disease. We use data fitting on models, with and without isolation, to estimate the basic reproductive numbers for the 2014 outbreak of EVD in Liberia and Sierra Leone.

STOCHASTIC STABILITY OF UNCERTAIN RECURRENT NEURAL NETWORKS WITH MARKOVIAN JUMPING PARAMETERS

引用

Acta Mathematica Scientia 2015年第5期35卷 1122-1136页

作者： M.syed ali Department of Mathematics Thiruval luvar University

In this paper, global robust stability of uncertain stochastic recurrent neural networks with Markovian jumping parameters is considered. A novel Linear matrix inequal- ity（LMI） based stability criterion is obtained to guarantee the asymptotic stability of uncertain stochastic recurrent neural networks with Markovian jumping parameters. The results are derived by using the Lyapunov functional technique, Lipchitz condition and S-procuture. Finally, numerical examples are given to demonstrate the correctness of the theoretical results. Our results are also compared with results discussed in [31] and [34] to show the effectiveness and conservativeness.
