The researchers then look at the effectiveness of a number of ways of assessing teachers, including classroom observations, value-added measures, pupil feedback, judgements from senior leaders, self-reports and looking at lesson plans and assignments and teacher portfolios, including reflective logs.
In case of missing observations, values are carried backwards or forward from the available observation, leaving a delta-value of 0. True observations reflect those with observations at both baseline and follow-up.
The observation value of each event is x1, x2, …, x n respectively.
Firstly, replace indicator function in histogram by smooth kernel function, and then set estimation interval center as sample observation value.
FDIA theory based on nonlinear model is much more complicated because the state variable and observation value has nonlinear relationship.
The state value (f_{s}) is the "true value" and unobservable except the well data, and the state value (w) is regarded as "observation value".
The observation value can be expressed as val = valreal + Δ, which is a combination of the real value of the environment valreal and error Δ.
The static solution uses the actual observation value of the lag period of each sequence to determine the next forecast value.
where o(c) represents the observation value for a given context c, and r(c) is a normally distributed random noise with zero mean and unit variance.
(11 where ( {widehat{lambda}}_dleft t,kright) ) represents the noise level (noise power spectra) and ( {Y}_k^2left t,kright) ) represents the power spectra of noisy speech (observation value).
Therefore, the channel access conditions at a slot depends on the present state of each node and the historical observation value.
