In the Foster synthesis above, the expansion of the function is the same procedure in both the Foster I form and Foster II form. It is convenient, especially in theoretical works, to treat them together as an immittance rather than separately as either an impedance or an admittance. It is only necessary to declare whether the function ...
Foster's reactance theorem. Foster's reactance theorem is an important theorem in the fields of electrical network analysis and synthesis. The theorem states that the reactance of a passive, lossless two-terminal (one-port) network always strictly monotonically increases with frequency. It is easily seen that the reactances of inductors and ...
Foster's second form of driving point impedance consists of series connected LC anti-resonators (parallel LC circuits) and is most useful for band-stop filters. Further theoretical work on realizable filters in terms of a given rational function as transfer function was done by Otto Brune in 1931 [ 13 ] and Richard Duffin with Raoul Bott in ...
The black dashed line indicates a virtual photon. Förster resonance energy transfer (FRET), fluorescence resonance energy transfer, resonance energy transfer (RET) or electronic energy transfer (EET) is a mechanism describing energy transfer between two light-sensitive molecules (chromophores). [1] A donor chromophore, initially in its ...
Children of the United Kingdom's Child Migration Programme – many of whom were placed in foster care in Australia. Foster care is a system in which a minor has been placed into a ward, group home (residential child care community, treatment center, juvenile center etc.), or private home of a state-certified caregiver, referred to as a "foster parent", or with a family member approved by the ...
Kid Cosmic. Foster's Home for Imaginary Friends is an American animated television series created by Craig McCracken for Cartoon Network. It was produced by Cartoon Network Studios as the network's first show animated primarily with Adobe Flash, which was done both by Cartoon Network Studios in Burbank and in Ireland by Boulder Media.
In 2016, there were 437,465 children in foster care in the United States. [14] 48% were in nonrelative foster homes, 26% were in relative foster homes, 9% in institutions, 6% in group homes, 5% on trial home visits (where the child returns home while under state supervision), 4% in preadoptive homes, 2% had run away, and 1% in supervised independent living.
