We introduce delays in a tuberculosis (TB) model, representing the time delay on the diagnosis and commencement of treatment of individuals with active TB infection. The stability of the disease free and endemic equilibriums is investigated for any time delay. Corresponding optimal control problems, with time delays in both state and control variables, are formulated and studied. Although it is...

Interleaved echo-planar imaging (EPI) is an ultrafast imaging technique important for applications that require high time resolution or short total acquisition times. Unfortunately, EPI is prone to significant ghosting artifacts, resulting primarily from system time delays that cause data matrix misregistration. In this work, it is shown mathematically and experimentally that system time delays...

This paper discusses the modeling and analysis of Networked Control Systems (NCSs) where sensors, actuators, and controllers are distributed and interconnected by a common communication medium. Therefore, multiple distributed communication delays as well as multiple inputs and multiple outputs are considered in the modeling algorithm. In addition, the asynchronous sampling mechanisms of distrib...
