Video transport over error-prone channels may result in loss or erroneous decoding of the video data. Error concealment is an effective mechanism to reconstruct the video data. In this paper, we review error-concealment methods and introduce a new framework, which we refer to as second-generation error concealment. All the error-concealment methods reconstruct the lost video data by making use ...

| This paper proposes a methodology, implemented in a tool, to automatically generate the main classes of Error Control Codes (ECCs) widely applied in computer memory systems to increase reliability and data integrity. New code construction techniques extending the features of previous Single Error Correcting (SEC)-Double Error Detecting (DED)-Single Byte Error Detecting (SBD) codes have been i...

This paper aims to propose the construction of the S. PERERE (Simulation of Performance in Error and Recovery), a computational simulator of the human behavior whose goal is to produce, at random, human error states during the accomplishment of a task. It is expected that, from the results, the S. PERERE contributes to the systems engineer in the elaboration of projects which are based on the c...

This paper proposes a new error metric: discrete curvature error metric to generate the LOD meshes. Discrete curvature is a new formalized curvature as simplification criterion. It can represent surface shape well and be computed with geometric attributes, not any smooth approximation. Our new error metric is based on the discrete curvature so that LOD can be generated precisely, and controlled...

Goal-directed human behavior is enabled by hierarchically-organized neural systems that process executive commands associated with higher brain areas in response to sensory and motor signals from lower brain areas. Psychiatric diseases and psychotic conditions are postulated to involve disturbances in these hierarchical network interactions, but the mechanism for how aberrant disease signals ar...

The mesh adaptation is a classical method for accelerating and improving the PDE finite element computation. Two tools are generally used: the metric [10] to define the mesh size and the error indicator to know if the solution is accurate enough. A lot of algorithms used to generate adapted meshes suitable for a PDE numerical solution for instance [15, 1] for discrete metrics, or [15, 2] for th...
