For some criteria (e.g., cost), it may be possible to assess the performance of the alternatives numerically, whereas, for others (e.g., quality), it may only be feasible to obtain an ordinal ranking of the alternatives or to allocate them to verbally defined levels of performance (e.g., poor, reasonable, and excellent).
The idea of the design approach is to adjust the triggering conditions such that the deviation between the disturbance rejection behavior of the event-based control system and a continuous-time state-feedback system is less than a desired bound, which is defined as level of performance.
These standards define the level of performance required for the successful achievement of work expectations and specify what the consumers can expect from the practitioners [ 27].
Comprehensive geriatric assessment serves to define an initial level of performance, and yields information that may help guide physician decision about treatment after taking into account projected life-expectancy and potential tolerance to side-effects.
A pilot study to define baseline levels of performance in acute stroke care and rehabilitation facilities has been described previously in a separate protocol [ 10].
By limiting the stimulus presentation time, we can determine the maximum number of visual items an observer can correctly enumerate at a criterion level of performance (counting threshold, defined as the number of visual items at which ≈63% correct rate on a psychometric curve), without confounding by eye movements.
The first of 4 steps in the SBM-R process is to establish evidence-based and locally relevant standards that define the desired level of performance in a service delivery area.
Mental workload is defined as an individual's "costs to achieve a particular level of performance it emerges from the interaction between the requirements of a task, the circumstances under which it is performed, and the skills, and perceptions" [ 15].
In the meantime, it has become commonplace for research groups to define new classifiers with a potentially higher level of performance than existing classifiers [ 13- 21].
The level of performance (defined by the shortest interstimulus interval (ISI) for tasks in which the subjects achieved a certain level of performance in one block and a shortened ISI in the following block) in all six MT-trained tasks was significantly increased in the last three training sessions compared with the first three training sessions (paired t test, P < 0.001, Table I).
In the healthcare accreditation context, a standard is defined as "a desired and achievable level of performance against which actual performance is measured".
