Lie detection operations. In other words, the DKS model may have a discrete knowledge base (DKB) of essential components needed for task resolution, while for nDKS, DKB is absent and, hence, a "global" or bi-hemispheric search occurs. Based on the latter premise, a 'lie detector' system was designed as described in . A pattern of blood-flow-velocity changes is obtained in response to questions that include correct and incorrect answers. The wrong answer will elicit bi-hemispheric activation, from correct answer that activates unilateral response. Cognitive polygraphy based on this system is devoid of any subjective control of mental processes and, hence, high reliability
Failure detector the failure detectors would find the programs that finally crashed in a process, whereas accuracy means that correct decisions that the failure detectors made in a process. The degrees of completeness depend on the number of crashed process is suspected by a failure detector in a certain period. The degrees of accuracy depend on the number of mistakes that a failure detector made in a certain period. Failure detectors can be categorized in the following eight types: The properties of these failure detectors are described below: In a nutshell, the properties of failure detectors depend on how fast the failure
