  • Publication number: 20190250986
    Abstract: Systems, memory controllers, decoders and methods perform decoding by exploiting differences among word lines for which soft decoding fails (failed word lines). Such decoding generates extrinsic information for codewords of failed word lines based on the soft decoding. The soft information obtained during the soft decoding is updated based on the extrinsic information, and the updated soft information is propagated across failed word lines. Low-density parity-check (LDPC) decoding of codewords of failed word lines is performed with the updated soft information.

    Abstract: A method of designing a freeform surface optical system with dispersion elements is provided. A nondispersive spherical optical system comprising a nondispersive sphere is constructed. A dispersion element is placed on the nondispersive sphere to construct a dispersive spherical optical system comprising a dispersive sphere. The dispersive spherical optical system is constructed into a dispersive freeform surface optical system comprising a freeform surface. The coordinates of the feature data points on the freeform surface are kept unchanged, and the normal vectors are recalculated. The coordinates and new normal vectors are fitted to obtain a new freeform surface. An iterative algorithm is performed until all freeform surfaces are recalculated to new freeform surfaces.

  • Patent number: 10357742
    Abstract: The present invention relates to a method for inhibiting the formation of dioxin-like compounds in solid waste incineration flue gases, belonging to the field of cleaning of solid waste incineration flue gases. In accordance with the present invention, when incineration flue gases cool down to 500˜450° C., the flue gases are introduced into an inhibition reactor where copper chlorides in flue gas particulates mix and react with inhibitors to convert into copper metaphosphate so as to inactivate the copper chlorides which can catalyze the formation of dioxin-like compounds and control dioxin-like compound pollutants in incineration flue gases at the source. Compared with the prior art, the invention can effectively control the main formation ways of dioxin-like compounds in solid waste incineration flue gases by optimizing inhibitors and reaction conditions.

  • Patent number: 10360807
    Abstract: In non-limiting examples, media can be created from any type of existing content. An exemplary media may be an assignment media (e.g. document) that is created for educational purposes. Content that is unassociated with a learning management system may be accessed. Input may be received requesting creation of an assignment media based on the accessed content. The request may be received through a learning management application, where the assignment media may be created based on the received input. Creation of an assignment media automatically associates the assignment media with a user account of a learning management application and a distributed network storage that corresponds with the user account. In some examples, the created assignment media may comprise one or more portions of the accessed content. The created assignment media may be accessed through the learning management application. Other examples are also described.
