However, the phenomenon that wiretap channel is better than primary channel is very common in wireless environment due to the non-controllability of channel.
This paper is concerned with the boundary controllability of non-scalar linear parabolic systems.
This method proved to be simple to operate, allowed improved controllability and non-toxicity of samples, and had a broad measurement range up to 4000 mg/l BOD.
The proposed method has many advantages (e.g. possibility of non-square controllers, provision to ensure controllability and observability, scalability, etc).
There exists much work on existence, asymptotic behavior, and controllability for deterministic non-autonomous partial (functional) differential equations with finite or infinite delays; see, for example, [17 20].
Therefore, there have been few reports about a fabrication of nanoshell-based 3D inverse structures using a non-vacuum process with thickness controllability.
For instance, we will investigate the qualitative properties of solutions for a new class of impulsive partial stochastic differential systems with non-instantaneous impulses by using resolvent operators, such as controllability, approximate controllability, optimal control, and stability.
In [7], instead of transforming the problem from a non-cylindrical domain into a cylindrical domain, Sun et al. studied the controllability problem directly in a non-cylindrical domain, when the control is put on the moving endpoint.
Ion implantation/etching techniques have the advantages of high controllability, high selectivity and non-thermal processing.
Remark 3.1 By the equivalent transformation in Section 2, Theorem 2.2 implies the exact controllability for in the non-cylindrical domain Q ˆ T k at the time T > T k ∗ (Theorem 2.1).
These fixed poles have two different origins: some are present, whatever be the considered control problem, because of possible non minimality of the state description (in the Kalman sense, i.e. controllability and observability).
