查询词典 sufficient condition

Under the condition of sufficient water supply, ETa can be calculated with ETp; While, under the condition of the soil wilting point was smaller than 0.37, ETa equals to 0; when under the condition of insufficient water supply, the equation could be expressed as ETa = Sw×ETp.

As an extension, we also obtain some sufficient and necessary conditions under which M_c is left Fredholm and left Weyl for some left invertible operator C, respectively.In chapter 2, the sufficient and necessary condition under which the difference of two idempotent operators on infinite dimensional Hilbert spaces is Fredholm (in-vertible) is discussed. In addition, some equivalent conditions under which products and differences of projections in a C~*-algebra are Moore-Penrose invert-ible are obtained.

Modeling and stability analysis problem of linear switched system are emphasized in this part and main results include:(1) Through investigation in the projection of 〓 on x, where x denotes continuous state vector, a series of sufficient conditions for stability, asymptotic stability and unstability of linear switched system's equilibrium in the sense of Lyapunov are achieved. And also, a sufficient and necessary condition for state bounded stability of linear switched system is received.(2) For a class of periodical linear switched system whose switching sets are a group of ordinal lines starting from the original point, it's proved that state bounded stability can be defined by the running characteristic in a single period (3) Based on linear switched system, the concept of linear switched system network is put forward. Linear switched system network is a complex network interconnected by many linear switched systems.

Via basic and descriptor adverse transformation of matrix, an equivalent standard linear system is derived. Sufficient and necessary conditions are established for observers with disturbance decoupling and LTR in systems. Analysis showed that the necessary and sufficient condition for observers with LTR is disturbance decoupling to any undnown inputs. So it is con verted to the problem that observers are designed with disturbance decoupling.

Hi Jill,a nice view of Grace of GOD.We can have a mind of possitive thinking if only we stay focused on the teachings of JESUS CHRIST.In HIS Infinite mercy HE has opened up the floodgates of Divine grace for total healing of ones whole being in whatever broken condition ,whether the mind,body or soul.The Saints were documented and known for having sufficient grace to perform miraculous cures over the centuries,even today many physicians and medical staff are bewildered by such healings encountered beyond medical technology.In all that is said,GODS Grace is good and sufficient for us all,Blessed be GOD forever!
