摘要： By evaluating a cell selection criterion S during scans for available public land mobile networks (PLMNs), a user equipment (UE) can avoid network service interruptions by not selecting PLMNs for which there exist no suitable cells. The cell selection criterion can be evaluated based on cell parameters either read during the PLMN selection procedure or locally stored before the PLMN selection procedure. It is possible to reduce the time required for PLMN scans and UE power consumption.

摘要： According to one embodiment, a method comprises receiving at a scheduler a change to a weight assigned to a consumer. The method further comprises utilizing, by the scheduler, a weighted proportional-share scheduling algorithm to maintain fairness in allocating shares of a resource to competing consumers in accordance with the changed weight. According to another embodiment, a system comprises at least one resource, and a plurality of competing consumers desiring to use the resource(s). A scheduler allocates shares of the resource(s) to the competing consumers according to a weighted proportional-share algorithm. A controller monitors at least one of performance of the competing consumers and utilization of the resource(s), and controls the performance and/or utilization by dynamically changing a scheduler parameter. The scheduler maintains fairness in allocating shares of the resource(s) to the competing consumers in accordance with the dynamically changed scheduler parameter.

摘要： A method and system for workload-aware request in cluster-based network servers. The present invention provides a web server cluster having a plurality of nodes wherein each node comprises a distributor component, a dispatcher component and a server component. In another embodiment, the present provides a method for managing request distribution to a set of files stored on a web server cluster. A request for a file is received at a first node of a plurality of nodes, each node comprising a distributor component, a dispatcher component and a server component. If the request is for a core file, the request is processed at the first node (e.g., processed locally). If the request is for a partitioned file, it is determined whether the request is assigned to be processed locally at the first node or at another node (e.g., processed remotely). If the request is for neither a core file nor a partitioned file, the request is processed at the first node. In one embodiment, the present invention provides a method for identifying a set of frequently accessed files on a server cluster comprising a number of nodes. Embodiments of the present invention operate to maximize the number of requests served from the total cluster memory of a web server cluster and to minimize the forwarding overhead and disk access overhead by identifying the subset of core files to be processed at any node and by identifying the subset of partitioned files to be processed by different nodes in the cluster.

摘要： The present invention relates to electronic mail. In particular, it relates to a method and system for processing electronic mail, wherein mails are stored in a space efficient way by removing redundancy from the content. Prior art is known for doing a limited version of this on a mail client. In order to provide a method and system which is adequate for server operation it is proposed to perform the steps of: splitting the content of an incoming e-mail into elementary mail segments by parsing and optionally normalizing the e-mail body based on a regular grammar with transduction rules; computing a unique ID for each elementary mail segment; storing the normalized or original form of an elementary mail segment together with a link to its respective parent elementary mail segment in a table in a way retrievable by said unique ID; and reconstructing an original e-mail from a concatenation of a respective sequence of said elementary mail segments wherein the unique ID for each elementary mail segment is used as a key for accessing said table and retrieving the respective elementary mail segment.

摘要： An embodiment of a method of selecting a heuristic class for data placement in a distributed storage system begins by forming a general integer program which models the data placement and forming a specific integer program which models a heuristic class for the data placement. The general and specific integer programs each comprising an objective of minimizing a replication cost. The method continues with solving the general integer program which provides a general lower bound for the replication cost and solving the specific integer program which provides a specific lower bound for the replication cost. The method concludes with selecting the heuristic class if a difference between the general lower bound and the specific lower bound is within an allowable amount.

摘要： A data model represents semantic information associated with objects stored in a file system. The data model includes a first object identifier, a second object identifier and a relation identifier. The first object identifier identifies a first object stored in the file system. The second object identifier identifies a second object stored in the file system, wherein the second object is related to the first object. The relation identifier identifies a relationship between the first object and the second object.

摘要： An image display station provides real time selectively zoomed direct display of a received high resolution image stored in image memory. The memory provides storage of the image input data for making available for pixel processing in each of subsequent clock intervals successive groups of adjacent pixel data values throughout a portion to be displayed of the image. User zoom control, by mouse input, selectively establishes a zoom factor for zooming of the input image. User pan control allows selecting display of desired regions of the zoomed image. User contrast control of the zoomed image is provided also by the mouse. Bilinear pixel processing of the successive groups of adjacent pixel data values is carried out throughout the displayed portion of input data within the time period of a single video display frame in accordance with the zoom factor established by the mouse input for such frame. The processing circuitry utilizes a start position in response to the user pan input for data made available from the image memory to define a displayed region of the zoomed image. The processed groups of data are pipelined and converted to analog form for on-the-fly real time video display with display contrast controlled from contrast data lookup according to the contrast input. Each of successive video frames can have a different such zoom factor and the displayed region of the zoomed image is position-shiftable by the pan input by fractional increments from one video frame to the next.

摘要： A wireless receiver for receiving a signal with a characteristic pattern includes a predictor for predicting the presence of a non-zero value of the characteristic pattern. A tracker tracks a noise component in the received signal between predicted non-zero values. The resulting noise component is subtracted from the received signal to output a processed signal, which is then decoded by a pattern discriminator and demodulator. The wireless receiver is less sensitive to noise and interference.
