Adaptive format conversion information as enhancement data for the high-definition television migration path
… research indicates that a scalable video codec based on adaptive format conversion (AFC) information may be ideally suited to meet the demands of the migration path for high-definition television. Most scalable coding schemes use a single format conversion technique and encode residual …

Scalable video
… a video stream is encoded into two kinds of layers, namely the base layer and the enhancement layer. The decoder must process the base layer in order to display minimally acceptable video quality. For higher quality, the decoder simply combines the base layer with one or more enhancement …

Adaptive format conversion information as enhancement data for scalable video coding
… transmitting a single independently coded base layer and one or more dependently coded enhancement layers. Clients can decode the base layer bitstream and none, some or all of the enhancement layer bitstreams to obtain video quality commensurate with their available resources. In many …

An investigation of the effect of dynamic and static loading to geosynthetic reinforced pavements overlying a soft subgrade
… (dynamic in nature), rapid deterioration of the base layer material and progressive permanent deformation of the surface will occur. This not only reduces the serviceability of the pavement structure but also its design life. In this study, reinforcement geosynthetics (geogrids and geotextiles) …

Joint design of multi-resolution codes and intra / inter- layer network coding
… coding process consists of MR source coding, layer coding and multi-stream coding. The source coding considers the allocation of codeword length to the two layers and use base layer percentage as the parameter. In the network coding model, we present two coding schemes, intra-layer and …

Asphalt Perpetual Pavement Design: Utilizing Existing Pavement Systems in Ohio
… the basis of determining the condition of the AC base layer. The data were used to calculate layer moduli by way of back-calculation from the Evercalc 5.0 program as well as tensile strain at the bottom of the AC base layer. Layer moduli and strain values were based on 9000 pound load applied to …

Evaluation of analytical and experimental methods to predict constrained layer damping behavior
Constrained layer damping (CLD) for three layer beams with viscoelastic cores and aluminum or graphite/epoxy composite laminate outer layers was investigated for model comparison, sensitivity to design parameters, and evaluation of experimental loss factor estimation techniques. Model comparison …
