Television's liveness has long been seen as one of its key features. This paper argues that “liveness” is not a textual feature, but a more fundamental category (in Durkheim's sense) that contributes to underlying conceptions of how media are involved in social organization through their provision of privileged access to central social “realities.”Here liveness is like a chemical or a DNA trace, or like a form of noise or disinformation. Sanden refers to variegations of temporal liveness, spatial liveness, …Restart the pod that fails with liveness or readiness checks. Then, make sure that this pod is being deployed on the Amazon EKS worker node where the preceding changes were made.

Liveness is the availability of a finalizing chain. If the chain stops finalizing or users are not able to access it easily, those are liveness failures. Extremely high cost of access could also be considered a liveness failure. Liveness. The notion of liveness is fundamental for the detection and avoidance of deadlocks. A transition t is live with respect to a marking μ 0 if for each μ ∈ R ( N, μ 0) there exists a firing sequence σ such that μ enables t. A net system is live with respect to the initial marking if every transition is live.

In facial recognition, liveness detection is used to distinguish between a live image and a 2D printed, 3D printed, or digital representation of a user’s face.
