    Abstract: The ability to remove a watermark from an encoded image by reversible watermarking opens the possibility of various novel applications. Several such applications are detailed. One permits different classes of consumers to gain access to different versions of an image. A pristine image is intentionally degraded in some fashion, and distributed to consumers. By reference to one or more watermarks in the degraded image, some or all of the degradation can be removed, or transformed to a less-objectionable state. Through such arrangements, image consumers with different needs can gain access to versions of the image having differing qualities.

    Abstract: The technical challenges for a smooth transition between using both a thermodynamic hydrate inhibitor (THI) and a kinetic hydrate inhibitor (KHI) to simply using only the KHI in multiple tie-in gas natural gas production systems is solved by adding more THI in a first pipeline leg of the production system while ceasing adding THI in a second pipeline leg of the system. Further, more KHI is added into the second leg of the system, and subsequently THI is gradually and/or slowly reduced in the remaining legs of the system until only KHI is being injected, after which the KHI amount in all legs may be reduced to the equilibrium or steady-state levels.

    Abstract: The present invention provides method and apparatus for designing modulation and coding set of communication System. The method for designing modulation and coding set designs a proper set of modulation and coding schemes (MCS), based on probability distribution of the quality of received signal in the communication system, so as to optimize the whole performance of the communication system. The method comprises the steps of: acquiring the probability distribution of the quality of the received signal in the communication system; performing a calculation on the target performance of the communication system based on the acquired probability distribution of the quality of the received signal and a plurality of MCSs, to design a proper set of MCSs for the communication system, so that a region where the probability of the quality of the received signal appears more frequently are provided with more levels of the MCSs.

    Abstract: A method of imperceptibly embedding a code signal in a media signal encodes auxiliary information in frequency components of the media signal. This method forms a code signal comprising a plurality of frequency components. The method embeds the code signal into the media signal by adjusting the frequency component relative to a neighboring component. The method changes selection of the plurality of frequency components corresponding to the codes signal for different instances of embedding the code signal in the media signal. The code signal may be used to encode a combination of fixed and variable message information in audio and image signals, including video. In one application, the attributes of the code signal are measured to determine broadcast signal quality. In another, the code signal robustly carries auxiliary information in distribution channels where distortion is common, such as compression, broadcast distortion, packet loss, digital to analog conversion, and ambient air transmission.

    Abstract: The invention is directed to a metallocene catalyst system comprising an inert silica support having pores with a peak pore volume of greater than about 0.115 mL/g at a pore diameter between about 250 Angstroms and about 350 Angstroms, and an alumoxane activator, with the metallocene being bound substantially throughout the support. The activator is grafted to the support in a solvent at a reflux temperature of toluene to obtain an aluminoxane on silica, and a metallocene component is added to make a MCS having a metallocene loading of about 2 wt %. This facilitates the production of metallocene catalyst systems having increased catalytic activity than previously recognized that is at least about 20 percent higher than the catalytic activity for a metallocene loading of about 1 wt % where the activator is grafted to the support at room temperature.

    Abstract: A method for improving precision in FFT calculations. For each iteration in an FFT implementation, a constant normalization multiplier is inserted such that the dynamic ranges of the input and output are the same. The final FFT output is multiplied by a constant normalization factor given by the number of iterations and the constant normalization multiplier.
