Abstract: Fractional calculus is now used in a variety of domains, including physics and engineering which have two problems in their study are the differentiation and the discontinuity problems.

As randomized controlled trials are not always feasible, quasi-experimental methods, such as regression discontinuity design, can expand the scope of clinical investigations aimed at causal inference ...

Abstract: This brief studies the fixed/preassigned-time stability problems for a class of time-varying discontinuous system modeled by ordinary differential equation (ODE). By using a special ...
