摘要： An object of the present invention is to reduce the incompleteness of the surface state due to lattice constant and steric hindrance, which was heretofore nearly unavoidable, in the surface treatment of light-emitting semiconductor nanoparticles. The present invention provides an excellent luminescent material that has enhanced photoluminescence efficiency, reduced photoluminescence spectrum width, and increased chemical resistance. Specifically, the present invention provides a luminescent material comprising semiconductor nanoparticles having a mean particle size of 2 to 12 nm and a band gap of 3.8 eV or less, each of the semiconductor nanoparticles being coated with a silicon-containing layer, the semiconductor nanoparticles in the luminescent material having a peak emission wavelength 20 nm or more towards the longer-wavelength side than the peak emission wavelength of the semiconductor nanoparticles alone.

摘要： A binary coding and decoding method and apparatus for MVD (Motion Vector Difference) absolute values, includes: dividing symbols for MVD absolute values to be coded into a plurality of subsets according to probability distribution properties; assigning a binary codeword for each subset; assigning a binary codeword for each symbol in each subset; concatenating and outputting the binary codeword for each subset and the binary codeword for each symbol in the subset, as the binary coding result. At the decoding side, decoding operations are performed by using a principle corresponding to that at the coding side. In this manner, the invention makes full use of the source properties on one hand, and effectively prevents the codeword length from being too long on the other hand. It has been experimentally testified that a better compression effect may be achieved during arithmetic coding process and thus the image coding performance may be improved effectively.

摘要： The provisioning process of the present invention first determines the average number of units of the system resource that are held per call. This parameter is a function of the call model and call-related event holding times. The average number of units is used, along with the Busy Hour Call Attempts to determine the holding rate, Rresource, of that particular call-related event to be allocated memory. The holding rate is then used by ┌Rresource +7{square root over (Rresource)}┐ to determine the number of resources required to be allocated to the call-related event.
