    摘要： A method and system for identifying nodes with similar content. In one aspect, the method comprises determining a structure of a network of nodes, said structure defined by incoming links and outgoing links between nodes within said network, grouping said nodes within said network into a first set of modules, calculating a first modularity value between each of the modules within the first set, said modularity value indicating a degree of similar content within each module, calculating a topical relevance value for each of the modules, selecting those modules whose topical relevance value exceeds a threshold value and calculating an authority score for the selected modules.

    摘要： A system and method for estimating sample clock frequency offset (εs) in a digital radio mondiale (DRM) system such as, for example, DRM receivers. The system and method includes using a relationship given by the following equation: ɛ s = linearfit ( angle ⁢ ( P G m P G ⁢ _ ⁢ tr m P G m ⁢ - ⁢ cycle P G ⁢ _ ⁢ tr m ⁢ - ⁢ cycle ) , l ) × N 2 ⁢ π × cycle × ( N + L ) wherein the PGm is the gain pilot received in the mth symbol and PG—trm is the gain pilot transmitted in the mth symbol, the PGm-cycle is the gain pilot received in (m-cycle)th symbol, the PG—trm-cycle is the second gain pilot transmitted in (m-cycle)th symbol, the l is the index of the sub-carrier associated with the gain pilot, the N is a factor of a sample point number of a useful symbol, the L is a sample point number of a guard interval, and the cycle is the interval of two symbols which are inserted gain pilots at the same sub-carriers (l).

    摘要： A content provider broadcasts content to subscribers through a content distribution system. The content distribution system operator can capture broadcast content in accordance with policies established by the content provider and make the content available subsequent to the original broadcast in accordance with applicable business policies. Business policies are created by the content provider by modifying template information models which have associated rules. The content distributor stores the business policies and evaluates rules indicated by the business policies against attributes of a content asset to determine availability of the content asset.

    摘要： A heat exchanger fluid distribution manifold includes a manifold body defining a coolant fluid chamber, a single fluid inlet, and a plurality of fluid outlets. The single fluid inlet is configured to introduce a coolant fluid into the coolant fluid chamber. The plurality of fluid outlets are configured to remove the coolant fluid from the coolant fluid chamber. At least two of the plurality of fluid outlets are separated from the single fluid inlet by an unequal distance, and a coolant fluid flow rate at each fluid outlet is substantially uniform. The heat exchanger fluid distribution manifold may further include a plurality of serpentine walls along the coolant fluid chamber. Each serpentine wall comprises a spline feature located proximate to an individual fluid outlet. The spline features are optimized such that the coolant fluid flow rate is substantially uniform and a total pressure drop is less than about 2 kPa.
