Aspects of the subject matter described herein relate to simulating storage devices. In aspects, a test automation engine instructs a simulator to simulate a storage device having certain characteristics such as a storage area network. The test automation engine then tests an application against the simulated storage device. Tests may include storage management requests and storage access requests. A provider may translate a request to one or more operations suitable to perform the request on the underlying simulated device. Shadow copies and the results of other storage management-related operations may be shared across computers via aspects of a simulation framework described herein.

In current Distributed Storage Systems, applications may determine the device on which data shall be stored. The invention provides a method for automatically selecting an individual storage device within a DSS. A method for automatically classifying a node in a network comprises determining data classes, automatically classifying data of said data classes stored on a node, determining the amount of stored data per data class, calculating data dominance values for each of the data classes, receiving a request that indicates a data type according to one of said data classes, and providing said dominance value according to the requested data class. Further, a method for automatically organizing nodes in a network comprises receiving a request for storing data of a particular data type, transmitting the request to storage nodes, receiving from the storage nodes respective dominance values, and selecting the node with the highest dominance value for storing the data.

A method determines a path between a first and a radio station of a radio communication system, whereby the radio communications system comprises, in addition to the first and the second radio station, one or more additional radio stations. A frequency band subdivided in to a number of subbands is used in order to communicate between the stations. At least one subband for communicating is assigned to each radio station. The bath extends over one or more of the additional radio stations so that information between the first and the second (AP) radio station can be transmitted over the path. The path is at least partially determined by a radio installation transmits at least path identification information to the first radio station. The radio installation additionally transmits, at least a portion of the radio stations of the path, respective path identification information and radio station identification information from at least one other radio station of the path and/or from the first and/or from the second radio station, and transmits subband information over at least one subband assigned to the at least one radio station, and transmits subband information over at least one subband assigned to the at least one radio corresponding to the radio station identification information.

摘要:
A signal source for use as a frequency source or time keeping signal source includes a radioactive emission source generating a substantially periodic signal corresponding to a radioactive material's disintegration rate. A radioactive emission detector generates a radioactive emission detection signal and, to stabilize the detected periodic signal, a dead time controlling attenuator blanks or shuts off the radioactive emission detection signal for a selected dead time interval in response to each detected radioactive emission (i.e., a detected signal pulse or signal component) generated by the source. The dead time controlling attenuator output provides a long-term and short-term a stable periodic signal.

A new transcriptional co-activator that interacts with steroid/nuclear receptors has been identified. The peptide and its nucleic acid sequences are useful for modulating the activity of steroid/nuclear receptors and biochemical processes in which steroid/nuclear receptors play a role.

In the field of data storage on limited rewritability storage media, handling frequently changing databases may lead to unequal wear of storage segments. The invention discloses a method for modifying a database file, which ensures maximally distributed segment wear in that any writing of data records uses a next available segment after the last written segment; and a reading method. A data carrier according to the method, containing a database file with records having version numbers is also disclosed.
摘要:
A data transfer in a network comprises a first node sending out a request for a particular data unit, a second node receiving and analysing the request, detecting that it may provide the requested data unit and sending to the first node a message indicating that it may provide the requested data unit, the first node receiving and selecting the message and sending a second request to the second node to request transfer of the particular data unit, and the second node transferring the particular data unit upon reception of the second request. A method for assigning a priority to such data transfer in a network comprises the first node assigning an identifier corresponding to a first priority to the request, the second node evaluating the identifier and, based on the identifier, calculating a second priority and assigning the calculated second priority to said transfer.

A mounting apparatus for mounting a planar member (10) comprises a base (200), a pair of locking members (160) secured on the base, a supporting tray (130) secured on a bottom of the planar member and an operating shaft (110) pivotally attached to the supporting tray. A plurality of mounting holes (143) is defined in the supporting tray and each comprises an accommodating hole (142) and a retaining hole (144). A plurality of standoffs (210) formed on the base and each comprises a head portion (214) and a neck portion (212). A pair of arms is formed on the operating shaft and each defines a cutout for receiving the locking member. After the head portions of the standoffs are received in corresponding accommodating holes, the operating shaft is pushed towards the base. The planar member is attached to the base when the neck portions are received in corresponding retaining holes.
