On Subspace Codisk-Cyclicity
(University of Baghdad-College of Science, 2023)
Let N be a subspace of an infinite dimensional complex separable on a Hilbert space ℋ. The operator T ∈ ℬ(ℋ) is said to be N-codisk-cyclic, if there is a nonzero vector y in ℋ, then N ∩ {βTn y: β ∈ ℂ, |β| ≥ 1, n ∈ ℕ} is ...
Frequency Control of a Realistic Dish Stirling Solar Thermal System and Accurate HVDC Models Using a Cascaded FOPI-IDDN-Based Crow Search Algorithm
(Hindawi Limited, 2023)
Unbalancing the real power in power system leads to fluctuation in system frequency which can cause the several negative effects on the performance and reliability of the interconnected power system. Therefore, to deal ...
