Lie detection the 'source'. To use an MRI as a lie detector, an fMRI should be used by placing a magnetic band as a scanner on a subject's head. However, the neurobiological systems that relate to lying are currently poorly understood. The current consensus is that faced with a forced choice paradigm, in which a subject has the choice of telling the truth or spontaneously generating a lie, lying can be distinguished due to increased prefrontal and parietal lobe activity. More specifically, the superior medial and inferolateral prefrontal cortices show net activation in the process of spontaneous lie generation (which involves suppression
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
