Synchronization of Fractional-Order Chaotic Systems with Model Uncertainty and External Disturbance

Mathematics, 2021
This paper is concerned with complete synchronization of fractional-order chaotic systems with both model uncertainty and external disturbance. Firstly, we propose a new dynamic feedback control method for complete synchronization of fractional-order ...

The Dynamic Effects of Aggregate Demand and Supply Disturbances [PDF]

, 1988
We interpret fluctuations in GNP and unemployment as due to two types of disturbances: disturbances that have a permanent effect on output and disturbances that do not. We interpret the first as supply disturbances, the second as demand disturbances. Demand disturbances have a hump-shaped mirror-image effect on output and unemployment.

Crack propagation mechanisms and stress evolution of floor under dynamic disturbance in deep coal mining

Yantu gongcheng xuebao, 2018
Inrush accidents are easily and frequently caused under high geostress and rising of dynamic disasters which induce crack propagation of rock mass in deep coal mining. So it is important to study the crack propagation mechanisms under dynamic disturbance.

Phase Angle as an Early Functional Biomarker of Cancer‐Related Fatigue in Pediatric Oncology: A Prospective Longitudinal Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric cancer remains a leading cause of morbidity and mortality worldwide, particularly in low‐and middle‐income countries. Cancer treatment may impair nutritional status, alter body composition, and exacerbate cancer‐related fatigue (CRF).
