  • Patent number: 10411266
    Abstract: Provided are: a dry reforming catalyst, in which a noble metal (M) is doped in a nickel yttria stabilized zirconia complex (Ni/YSZ) and an alloy (M-Ni alloy) of the noble metal (M) and nickel is formed at Ni sites on a surface of the nickel yttria stabilized zircona (YSZ); a method for producing the dry reforming catalyst using the noble metal/glucose; and a method for performing dry reforming using the catalyst. The present invention can exhibit a significantly higher dry reforming activity as compared with Ni/YSZ catalysts. Furthermore, the present invention can have an improved long-term performance by suppressing or preventing the deterioration. Furthermore, the preparing method is useful in performing the alloying of noble metal with Ni at Ni sites on the Ni/YSZ surface and can simplify the preparing process, and thus is suitable in mass production.

  • Patent number: 8836702
    Abstract: A ray tracing core comprises a ray tracing unit (RTU), a control unit, and a tree build unit (TBU). The ray tracing unit performs ray tracing based on a spatial partitioning structure. The control unit calculates the degree of complexity of the spatial partitioning structure by monitoring the load state of the ray tracing unit. The tree build unit builds the spatial partitioning structure having the degree of complexity which is calculated. The load state is determined based on a frame rate which is processed in the pertinent unit. The spatial partitioning structure applies a K-dimensional tree. For example, the degree of complexity can be modified according to either the maximum primitive number of a leaf node with respect to a K-dimensional tree structure or a tree depth.

  • Publication number: 20140176550
    Abstract: A method for selecting a MIP-map level is used for Texture Mapping based on Global Illumination. The method for selecting the MIP-map level confirms Object information on at least one object on a screen. The object information can include the number, shape, and the composition of objects on the screen, and/or the spatial position of a relevant object on the screen. Based on the object information, a MIP-map level selection algorithm is determined. The MIP-map level selection algorithm includes ray tracing and/or distance measuring, wherein the ray tracing selects the MIP-map based on the Differential value of adjacent rays, and the distance measuring can select a MIP-map by calculating the distance at which the ratio of pixels and texels reach 1:1. Based on the determined method, the MIP-map level is selected.

  • Patent number: 8125317
    Abstract: A portable device includes an RFID reader for detecting a tag information of an RFID tag, a memory for storing the tag information detected by the RFID reader, and a controller. When a read command for the RFID tag is input and the tag information is valid, the controller controls the RFID reader to retrieve the tag information of the memory. If the tag information is invalid, the controller controls the RFID reader to re-read the RFID tag. The controller can determine whether the tag information is valid using the time and location. Because unnecessary operation can be omitted to read tags, power consumption is reduced and tag information check time is shortened.

  • Patent number: 7660860
    Abstract: A method for determining a transmission time of collected context information at a sensor node in a communication system that includes a client, at least one sensor node collecting context information, and an access point (AP) forwarding the context information received from the sensor node to the client. The communication system operates in a session layer of protocol layers of open systems interconnection (OSI). The sensor node calculates a transmission period in which the collected context information is transmitted, and randomly determines a transmission time at which the context information is transmitted within the calculated transmission period. Since the collected context information is transmitted at the transmission time randomly determined by the sensor node, the load on the AP can be balanced.
