    摘要: A novel method for recovering carboxylic acid from a waste water stream is described. The method involves first neutralizing the carboxylic acid in the waste water with CaO or Ca(OH)2 to form calcium carboxylate. The resulting calcium carboxylate is then reacted with sulfite or sulfate to regenerate the carboxylic acid. The resulting waste water typically has a carboxylic acid content of at least 25-wt %.

    摘要: A manufactured stone block for use in building a structure having a front surface with a simulated natural stone appearance. A portion of an upper surface of the block includes a recessed mortar joint for a user to place mortar therein to secure the manufactured stone block to an adjacent surface.

    摘要: A search engine communicates with a broker to identify search result content associated with merchants that support purchases through an electronic commerce system provided by the broker. The results of a search can include some content associated with merchants that support purchases through the broker, some content associated with merchants that do not support purchases through the broker, and some content not associated with any merchant. The search engine visually distinguishes content in the search results associated with merchants that support purchases through the broker by displaying a badge, such as a graphical icon, with the content. The search engine can use different types of badges to indicate different characteristics of the merchants.

    摘要: The ability to examine the frequency content of a signal is critical in a variety of fields, and many techniques have been proposed to fill this need, including the Fourier and wavelet family of transforms. One of these, the S-transform, is a Fourier based transform that provides simultaneous time and frequency information similar to the wavelet transform but uses sinusoidal basis functions to produce true frequency and globally referenced phase measurements. It has been shown to be useful in several medical imaging applications but its use is limited due to high computational requirements of the original, continuous form. The described embodiments include a general framework for describing linear time-frequency transforms, using the Fourier, wavelet and S-transforms as examples. As an illustration of the utility of this formalism, a fast discrete S-transform algorithm is developed that has the same computational complexity as the fast Fourier transform.
