Lie great number of lies, depending on how the political wind blows." The question of whether lies can reliably be detected through nonverbal means is a subject of some controversy. Polygraph "lie detector" machines measure the physiological stress a subject endures in a number of measures while he/she gives statements or answers questions. Spikes in stress are purported to indicate lying. The accuracy of this method is widely disputed, and in several well-known cases it was proven to have been deceived. Nonetheless, it remains in use in many areas, primarily as a method for eliciting confessions or employment screening. Polygraph results
Failure detector failure detector "W" is weak in completeness, and the failure detector "S" is strong in completeness. They are both weak in accuracy. If all arguments above are satisfied, the reduction of a weak failure detector "W" to a strong failure detector "S" will agree with the algorithm within the distributed computing system. Failure detector In a distributed computing system, a failure detector is a computer application or a subsystem that is responsible for the detection of node failures or crashes. Failure detectors were first introduced in 1996 by Chandra and Toueg in their book "Unreliable Failure Detectors for Reliable Distributed
