    摘要： Systems and methods are provided for zero buffer copying, where such a system includes one or more high performance computing systems, each including one or more processors and a high performance memory. The system further includes a user space that includes a Java virtual machine (JVM) and one or more application server instances; and a plurality of byte buffers accesible to the JVM and the one or more application server instances. When a request is received by a first application server instance data associated with the request is stored in a heap space associated with the JVM, and the JVM pins the portion of the heap space where the data is stored. The data is pushed to a first byte buffer where it is accessed by the first application server instance. A response is generated by the first application server using the data, and sent by the first application server.

    摘要： The present invention relates to a method and apparatus for detecting a signal propagation type. The method comprises: calculating a similarity value of a currently received pulse response and a reference pulse response when a certain positioning base station of a UWB positioning system currently receives a pulse response from a certain positioning tag, the similarity value indicating the degree of similarity between the currently received pulse response and the reference pulse response, wherein the reference pulse response is a pulse response previously received by the positioning base station from the positioning tag; and determining the current type of signal propagation between the positioning base station and the positioning tag on the basis of the similarity value. The method and apparatus can detect the type of signal propagation between the positioning base station and positioning tag of the UWB positioning system.

    摘要： Methods and configurations controlling a converter having controllable power semiconductors, compare actual and target state values to obtain control difference values for a control unit producing setting voltage values. Control electronics provide control signals according to setting voltage values and transmit them to power semiconductors. The control unit generates voltage values so control difference values become small. Current and converter energy controls and energy balancing are performed jointly, actual state values are calculated by an observing unit based on setting voltage values considering measured current values and actual state intermediate-circuit energy values are calculated by an estimating unit considering measured intermediate-circuit energy values of positive and negative voltage sources. The observing and estimating units model the converter so actual state current and intermediate-circuit steady-state energy values correspond to error-free current and intermediate-circuit energy values. A periodic time-variant gain controller receives error-free values.
