A recent paper [Y.-Y. Chen, J.-S. Guo, F. Hamel, Traveling waves for a lattice dynamical system arising in diffusive endemic model, Nonlinearity, 30 (2017), 2334-2359] presented discrete Kermack-McKendrick epidemic and the authors proved existence of traveling wave solutions connecting disease-free equilibrium to equilibrium. However, boundary asymptotic behavior converge at $ +\infty is still ...

Cash management is concerned with optimizing costs of short-term cash policies of a company. Different optimization models have been proposed in the literature whose focus has been only placed on a single objective, namely, on minimizing costs. However, cash managers may also be interested in risk associated to cash policies. In this paper, we propose a multi-objective cash management model bas...

A total of 37,152 patients attended the Accident & Emergency (A&E) Department of Hospital Universiti Kebangsaan Malaysia (HUKM) from 1st January to 31st December 1998. Attendance during early hours (midnight to 0659 hrs.) constituted only 10.4% (3853 cases) whereas that for three other time periods of 0700-1159 hrs., 1200-1759 hrs., and 1800-2359 hrs. was 29.4% (10,927 cases), 30.8% (11,448 cas...
