The MVC+D standard specifies coding of Multiview Video plus Depth (MVD) data for enabling advanced 3D video applications. MVC+D defines that all views are coded with H.264/MVC encoder at equal spatial resolution. To improve compression efficiency it is possible to use mixed resolution coding in which part of texture views are coded at reduced spatial resolution. In this paper we evaluate the pe...

Marine seismic data from the Blake Outer Ridge offshore Florida show strong “bottom simulating reflections” (BSR) associated with methane hydrate occurence in deep marine sediments. We use a detailed amplitude versus offset (AVO) analysis of these data to explore the validity of models which might explain the origin of the bottom simulating reflector. After careful preprocessing steps, we deter...

We report here the design of a new type of high efficiency grating coupler, based on single crystalline Si nanomembrane overlay and stacking. Such high efficiency diffractive grating couplers are designed for the purpose of coupling light between single mode fibres and nanophotonic waveguides, and for the coupling between multiple photonic interconnect layers for compact three-dimensional verti...

We theoretically propose a silicon nitride (Si(3)N(4)) grating coupler (GC) with both ultrahigh efficiency and simplified fabrication processes. Instead of using a bottom distributed Bragg reflector (DBR) or metal reflector, a bottom Si grating reflector (GR) with comparable reflectivity is utilized to improve the coupling efficiency. The fully etched Si GR is designed based on an industrially ...

To delineate the spatial distribution of high saturation gas hydrate reservoirs in low-angle subduction areas Makran Accretionary Prism, we conducted seismic data interpretation and impedance inversion hydrates Prism comprehensively analyzed characteristics Nankai Trough Japan Shenhu Area South China Sea. The results show that features thick sediments, developed transport systems “two-way suppl...

Coring, geophysical logging, and in-situ temperature measurements were performed with the MARUM-MeBo200 seafloor rig to characterize gas hydrate occurrences in sediments of Danube deep sea fan, off Romania, Black Sea. The new drilling data showed no evidence for significant saturations within but presence free at depth bottom-simulating reflector (BSR). In-situ core-derived geochemical suggest ...

The submarine gas hydrate usually exists in the sediment on continental slope. bottom simulating reflector reflected seismic was identified as of stability zone. However, many BSRs may not find hydrate’s effective storage and its underlying free places. It is essential to identify saturation hydrate. resistivity can be used evaluate porosity saturation. boasts a high resistance surrounding sedi...
