  • Patent number: 8901527
    Abstract: An RRAM includes a resistive layer including a dielectric layer and surplus oxygen ions or nitrogen ions from a treatment on the dielectric layer after the dielectric layer is formed. When the RRAM is applied with a voltage, the oxygen ions or nitrogen ions occupy vacancies in the dielectric layer to increase resistance of the resistive layer. When the RRAM is applied with another voltage, the oxygen ions or nitrogen ions are removed from the vacancies to lower the resistance of the resistive layer.

  • Publication number: 20140331912
    Abstract: An apparatus for friction reduction and biofouling prevention is invented, which consists of an anodic electro-catalytic layer and a cathodic electro-catalytic layer installed on the submerged surface of a carrier. There is an insulating filling between the anodic layer and the cathodic layer. The layered coatings are applied with the use of electric arc spraying technique. A first DC power supply unit is connected to the anodic layer and the cathodic layer. The anodic layer, the cathodic layer, the DC power supply unit, and water together form the conducting path for water electro-catalysis. Hydrogen and oxygen gases are produced to form a thin gas film on the submerged surface to reduce friction and prevent biofouling on the carrier. Alternatively, the apparatus produces hydroxyl radicals to kill marine microorganisms and reduce the risk of biofouling and biocorrosion.

The DC power supply includes a positive pole electrically connected to the anodic microporous plate and a negative pole electrically connected to the cathodic microporous plate. Seawater is electrolyzed to generate hydrogen microbubbles adjacent to a surface of the cathodic microporous plate and to generate oxygen microbubbles adjacent to a surface of the anodic microporous plate, forming superhydrophobic surfaces on the surfaces of the anodic microporous plate and the cathodic microporous plate. Electric current flows through the anodic microporous plate and the cathodic microporous plate to prevent biofouling.

  • Publication number: 20140019610
    Abstract: A trace identifier is sent between a database client and a database server using a pre-login data package along with pre-login connection open requests through the TDS protocol. The trace identifier gets logged by client-side connection-related traces, by server-side traces, and by database engine traces. The trace identifier can be used to exactly correlate a physical connection on the client to a physical connection on the server. This enhances troubleshooting of the database system, particularly when there are many concurrent users and threads.

  • Publication number: 20140019478
    Abstract: A trace header with an activity identifier is sent between a client and a database server as part of a request message stream. The activity identifier gets logged by client-side connection-related traces, by server-side traces, and by database engine traces. The activity identifier can be used to exactly correlate a thread on the client to threads on the server. Additionally, specific threads within a database engine may be correlated using the activity identifier to track the threads that processed a particular request. This enhances troubleshooting of the database system, particularly when there are many concurrent users and threads.
