Due to the intermittent nature of target signals in passive surveillance operations (e.g. artillery firings may occur in short bursts only every few days), recursive estimation techniques (e.g. such as the extended Kalman filter [9]) may be ineffective, because the interval between signals is too large to allow persistent target tracking.
Any additional nose pokes during this interval were ineffective, i.e. not reinforced ("inadequate responding", [ 5, 54]).
There was encouragement to be had in Josh McEachran's assured performance, but Gaël Kakuta was substituted at the interval after another ineffective display.
Templeton also came on at the interval, for the ineffective Arnold Peralta, and the winger scored with his first touch.
However, only two of the 30 spring treatments analysed were categorised as ineffective and the wide confidence interval associated with the spring value indicates that this result should be treated with caution.
To facilitate the interpretation of our pooled estimates, we defined the effects of paracetamol compared with placebo as ineffective when the 95% confidence interval crossed the no effect line, showing no significant difference between groups.
The number of intervals The result of the number of intervals is expected to be a small number as a large number of intervals may cause the learning to be slow and ineffective [7, 19], and the small number of intervals is easier to understand.
Illumination at intervals greater than 24 h was ineffective, with no cured tumours and very little growth delay compared with untreated tumours.
That equaliser was timely, coming just before the interval, with Ramires's introduction for the ineffective André Schürrle ensuring the hosts ripped the momentum back for good.
An article in Time, Why long lectures are ineffective, suggested students could only focus for 15-minute intervals and therefore could not be expected to stay awake and engaged during the standard 50-minute lecture.
