12 The impact of Indo-Pacific climate feedback on the dynamics of El Niño Southern Oscil13 lation (ENSO) is investigated using an ensemble set of Indian Ocean decoupling experiments 14 (DCPL), utilising a millennial integration of a coupled climate model. It is found that elim15 inating air-sea interactions over the Indian Ocean results in stronger ENSO variability with 16 various degrees of am...

Unsteady flow is highly related to loss and aerodynamic performance degradation in the axial compressor. In this paper, dynamic mode decomposition method was used investigate in-depth structures evolutionary mechanisms of internal field. Four main were observed through field decoupling: oscillation tip leakage vortex (TLV) region, circumferential migration leakage-induced (LIV), rear part (RLV)...

Unprecedented economic achievement in China has occurred along with rising resource consumption and waste productions levels. The goal of sustainability requires the decoupling of economic growth from resource consumption (resource decoupling) and environmental degradation (impact decoupling). For this paper, the performances of resource decoupling (energy and water) and impact decoupling (wast...

This study presents a model-free robust input-output decoupling control with Nonlinear-Dynamic-Coupling Inversion/Inverter (NDCI) in U-control framework. Regarding the decoupling, an input/output (I/O) coupling matrix function is proposed to derive two decouplers (U-decoupler/functional inversion and D-decoupler/static inversion). A general existing theorem proved for sliding mode (MFSMC) lay f...

The notions of decoupling zeros of positive discrete-time linear systems are introduced. The relationships between the decoupling zeros of standard and positive discrete-time linear systems are analyzed. It is shown that: 1) if the positive system has decoupling zeros then the corresponding standard system has also decoupling zeros, 2) the positive system may not have decoupling zeros when the ...

Purpose: Parallel transmit technology for MRI at 7 tesla will significantly benefit from high performance arrays that offer efficiency and low mutual coupling between the individual array elements. A novel dual-mode with nested elements has been developed to support imaging human brain in both single-channel (sTx) parallel-transmit (pTx) excitation modes of a scanner. In this work, design, impl...

We propose a novel rank aggregation method based on converting permutations into their corresponding Lehmer codes or other subdiagonal images. Lehmer codes, also known as inversion vectors, are vector representations of permutations in which each coordinate can take values not restricted by the values of other coordinates. This transformation allows for decoupling of the coordinates and for per...

For a linear model of active car steering a robust decoupling control law by feedback of the yaw rate to front wheel steering was derived earlier. In the present paper this control law is extended by feedback of the yaw rate to rear wheel steering. A controller structure with one free damping parameter k D is derived with the following properties: i) Damping and natural frequency of the yaw mod...

This paper presents the study of a variable speed wind energy conversion system based on a Doubly Fed Induction Generator (DFIG) based on a sliding mode control applied to achieve control of active and reactive powers exchanged between the stator of the DFIG and the grid to ensure a Maximum Power Point Tracking (MPPT) of a wind energy conversion system. The proposed control algorithm is applied...
