The explanation of risk contagion among economic players—not only in financial crises—and how they spread across the world has fascinated scholars and scientists last few decades. Inspired by literature dealing with analogy between systems ecosystems, we model revisiting mathematical approach epidemiological models for infectious disease a new paradigm. We propose time delay differential system...

An effective and reliable fast braking system for three-phase induction motor designed with the combinations of two or more conventional braking methods are discussed in this paper. A series of experiments were conducted in order to find out the speed range at which the most effective and efficient braking occurs corresponding to each conventional braking method and also to determine the minimu...

in this study, a robust controller is designed for fuzzy network control systems (ncss) using the static output feedback. delay and data packet dropout affect on the stability of network control systems, and therefore, the asymptotic stability condition is established considering delay and data packet dropout. delay is time-varying while the lower and upper bounds for delay is defined, and the ...

The delay of gratification (DoG) in children is widely investigated with an experimental procedure originally called the "marshmallow test," whereas the studies on self-regulation (SR) in adolescents and adults usually use self-report questionnaires. Delay discounting (DD) measures simplify the DoG procedure and focus on monetary rewards. The aim of this study was to investigate age differences...
