Abstract: A heavy oil upgrading apparatus and upgrading method are provided in which the advance degree of thermal cracking of the heavy oil can be controlled when the heavy oil is upgraded by using supercritical water. A reactor 1 is maintained at a temperature and a pressure equal to or higher than critical points of water. In the reactor, a heavy oil and supercritical water are brought into contact with each other and the heavy oil is separated into a first phase composed of a heavy residual oil fraction obtained by thermal cracking and supercritical water dissolved in the heavy residual oil fraction and a second phase composed of the supercritical water and a light oil fraction extracted into the supercritical water, while advancing thermal cracking of the heavy oil. An interface detection unit 75 detects a height position of an interface between the first phase and the second phase in the reactor.  A control unit 7 controls the withdrawn amount of the mixed fluid of the heavy residual oil fraction and the supercritical water on the basis of the volume of the first phase found from the height position of the interface, so that a residence time of the mixed fluid of the heavy residual oil fraction and the supercritical water dissolved in the heavy residual oil fraction becomes a first residence time that has been set in advance.

Title: Multi-level significance maps for encoding and decoding
Inventor: NGUYEN NGUYEN
IPC: H03M7/40
Filed: 2012-10-18
Abstract: Methods of encoding and decoding for video data are described in which multi-level significance maps are used in the encoding and decoding processes. The significant-coefficient flags that form the significance map are grouped into contiguous groups, and a significant-coefficient-group flag signifies for each group whether that group contains no non-zero significant-coefficient flags. If there are no non-zero significant-coefficient flags in the group, then the significant-coefficient-group flag is set to zero. The set of significant-coefficient-group flags is encoded in the bitstream. Any significant-coefficient flags that fall within a group that has a significant-coefficient-group flag that is non-zero are encoded in the bitstream, whereas significant-coefficient flags that fall within a group that has a significant-coefficient-group flag that is zero are not encoded in the bitstream.
