Mathematical modeling of rail gun
The exit velocity of the launch object along with the values of electric and thermal conductivity at the interfaces between the rails and the armature of a rail gun are critical issues. This thesis, using finite element method, estimates the former by solving the proper multiphysics governing …

Mathematical modeling of infectious diseases
In this dissertation, we studied mathematical models of infectious diseases that consist of ordinary differential equations (ODEs) and partial differential equations (PDEs). An ODE model is formulated to describe the dynamics of wild mosquitoes when Wolbachia-infected female and male mosquitoes are …

Mathematical modeling of urban water management strategies
The rapid expansion of many western urban centers has nearly outstripped available stream, flow and groundwater re-sources requiring municipal water departments to initiate exhaustive searches for new water supplies. Among the most feasible alternatives being investigated to date are acquisition …
