Unconditional imbalance coefficients remain largely unaffected, cf. the corresponding lines in Tables 9 and 11.
Actually, the imbalance coefficients g 1,j and g 2,j are satisfied with |g 1,j |≫|g 2,j | for any practical transmitter front end.
Conditional imbalance coefficients increase during the crisis period when controlling for size and/or liquidity effects, cf. the top lines of Tables 8 and 11.
The subcarrier and mirror carrier channels are h+ and h− and the transmitter and receiver I/ Qimbalance coefficients are G1,G2 and K1,K2, respectively.
Both transmitter and receiver I/ Qimbalance coefficients G 1 = ( 1 + g T e j ϕ T ) / 2, G 2 = ( 1 − g T e − j ϕ T ) / 2 and K 1 = ( 1 + g R e − j ϕ R ) / 2, K 2 = ( 1 − g R e j ϕ R ) / 2 are the complex coefficients which can be determined by the total effective amplitude and phase imbalances of the transceivers, g and ϕ, respectively.
The effects of rotating speed, imbalance, damping coefficient, and friction coefficient on the micro-rotor system responses are studied.
The effects of rotating speed, imbalance, damping coefficient, impact stiffness, and friction coefficient on the micro-rotor responses are investigated in detail.
A rub-impact micro-rotor model with scaling nonlinear rub-impact force is presented and the nonlinear dynamic characteristics of the system in micro-electro-mechanical systems (MEMS) are investigated when the rotating speed, imbalance, damping coefficient, scale length and fractal dimension are regarded as the control parameters.
Special attention is also given to determine the effects of casing stiffness, friction coefficient, imbalance load and system damping characteristics.
