摘要： Oxazolidinium compounds are formed by the reaction of a halohydrin or an epoxide with a secondary amine and an aldehyde or a ketone. The oxazolidinium compounds are formed directly and do not require the reaction of a pre-formed oxazolidine with an alkylating agent. The compounds are useful as gas hydrate inhibitors in oil and gas production and transportation.

摘要： The present invention discloses a transmission resource assignment method for response signals, a feedback method of response signals and a processing method of response signals. The transmission resource assignment method for response signals according to the present invention includes the steps of: determining a list of mobile stations required to transmit response signals currently; determining the number of the response signals required to be transmitted by each mobile station; and assigning a frequency-domain sequence and a time-domain sequence for each mobile station to transmit the response signals; wherein for multiple mobile stations assigned with the same frequency-domain sequence, the time-domain sequence assigned to the mobile station required to transmit multiple response signal groups is divided into multiple subsequences to be used to transmit the multiple response signal groups of the mobile station respectively; and parts of the time-domain sequences of different mobile stations corresponding to the multiple subsequences are orthogonal to each other respectively.

摘要： 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.
