We live in a digital world, where we use digital tools and smart devices to communicate over the Internet. In turn, an enormous amount of data gets generated. The traditional computing architectures are inefficient in storing and managing this massive amount of data. Unfortunately, the data cannot be ignored as it helps businesses to make better de...

In this research, we examine a deterministic mathematical model to investigate the prevalence of corruption in society. We assume that corruption in society spreads like an infectious disease, and our model is based on this notion. The model’s equilibria are identified, and the stability of these equilibria is studied in depth. At the corruption fr...

The information about the bounded perturbations can be challenging to obtain for type 1 diabetic patients. Hence, the robust control law might not ensure tight glycemic control in certain physiological conditions. Unlike the conventional robust controller designs, an adaptive robust controller design can be a better candidate in such situations. Th...
