Abstract: Methods and systems generally include determining coordinated activity in social media movements on a social media channel. The method includes identifying a plurality of markers of coordinated activity through analysis of campaign signals from the social media movements. The plurality of markers includes a network dimension for representing how accounts are connected, a temporal dimension for representing patterns of messages over time, and a semantic dimension for representing a diversity of topics and meanings of the social media movements. The method includes analyzing the campaign signals indicative of the coordinate activity of the social media movements in the social media campaign including determining users within the social media campaign, determining clusters of users that make up the social media campaign and determining relationships between the users participating in the social media movements, and determining propagation patterns across clusters of users of the social media campaign.

Abstract: Computerized search methods and systems generally include presenting, to a user, a computer interface for specifying one or more search terms for a search query and presenting at least one selectable item corresponding to at least one of art M score and a cluster focus index (CFI) score filter for the search query. The methods and systems include generating an amended search query based on a selected item; and performing a search using the amended search query. The M score is calculated using the formula M score=count (alpha)+CFI (1-alpha), where the count is the overall number of members on a cluster focus map that has engaged with a target.

Abstract: A valence graph may be constructed that depicts words, phrases, links, objects, and the like that are preferred by one sub-cluster over another sub-cluster. Such valence graphs may use aggregated sets of clusters defined by users to display dimensions of substantive interest. The valence graph may be constructed by partitioning an online author network into at least one set of source nodes with a similar linking history to form an attentive cluster and at least one set of outlink targets with a similar citation profile to form an outlink bundle and then generating a graphical representation of attentive clusters and/or outlink bundles in the network to enable interpretation of network features and behavior and calculation of comparative statistical measures across the attentive clusters and outlink bundles, wherein at least one element of the graphical representation depicts a measure of an extent of a type of activity within the network.

Abstract: Attentive clustering includes constructing an online author network, wherein constructing includes selecting a set of source nodes (S), a set of outlink targets (T) from a selected type or types of hyperlinks, and a set of edges (E) between S and T defined by the selected hyperlinks, constructing a matrix of source nodes in S linked to targets in T?, wherein T? is derived by normalizing nodes in T, and partitioning the network into at least one set of source nodes with a similar linking history to form an attentive cluster and at least one set of outlink targets with a similar citation profile to form an outlink bundle. Attentive clustering may further include applying any lists specifying inclusion or exclusion of particular nodes. Frequencies of links between attentive clusters and outlink bundles may be measured and analyzed.

Abstract: This disclosure concerns systems and methods for classifying at least one contagious phenomenon propagating on a network. Classifying may be based on one or more of a peakedness, a commitment, a commitment by subsequent uses, a commitment by time range, and a dispersion related to engagement with the contagious phenomenon.

Abstract: A method and apparatus for radially expanding and anchoring a sleeve within a tube are provided. The apparatus includes a hydraulic expanding mandrel, a fluid source for supplying a first pressurized fluid and a second fluid to first and second pumps and a fluid control mechanism for selectively activating the second pump and for controlling the total volume of pressurized fluid discharged by the second pump. In order to radially expand and anchor the sleeve within the tube, the sleeve is first inserted within the tube. Then, the mandrel is inserted within the sleeve such that the mandrel and sleeve together define a substantially annular hydraulic pressure zone situated between the sleeve, the body of the mandrel and the seals.

Abstract: A swaging mandrel is inserted in a tube confined by a tube sheet or other surrounding structure. A pair of seals define the axial limits of a hydraulic pressure zone within the tube sheet in which radial expansion of the tube takes place in response to fluid pressure. At one side of the tube sheet, an elastomeric ring can extend beyond the tube sheet and, in response to the fluid pressure, produce an attenuated radial expansion force that bulges the tube. At the primary side of the tube sheet, an elastomeric ring, in response to the fluid pressure, causes arcuate segments of a cylinder positioned beyond the tube sheet to expand radially and flare the tube at the opposite side of the tube sheet.

A pair of seals define the axial limits of a hydraulic pressure zone within the tube sheet in which radial expansion of the tube takes place in response to fluid pressure. At the secondary side of the tube sheet, an elastomeric ring extends beyond the tube sheet and, in response to the fluid pressure, produces an attenuated radial expansion force that bulges the tube to produce a tight seal at the tube sheet surface and a positive mechanical interlock between the tube and the tube sheet.

Abstract: A leakage testing apparatus includes a pull bar surrounded by an array of arcuate segments having teeth that engage and deform the inner surface of a tube. When tension is applied to the pull bar, a cam forces the segments to move outwardly to contact the tube while maintaining a parallel relationship to said pull bar.

Abstract: A swaging apparatus includes a drawbar to be inserted in a tubular structure that is to be expanded radially. Two confinement structures define the axial boundaries of an annular pressure zone within which one or more elastically deformable pressurization rings are confined. One or both of these structures includes a plurality of arcuate segments elastically held together and presenting a cam surface. A cam ring interacts with that cam surface to radially expand a cylinder formed by the segments in response to swaging pressure, thereby preventing inelastic deformation of the pressurization rings.

Abstract: A method for radially expanding tubes within a tube sheet involves the application of radially expansive swaging forces from a pre-expander apparatus and a hydraulic mandrel. The pre-expander is used first and includes at least one primary expander and at least one secondary expander. The expanders surround and are compressed axially by a draw bar, thereby producing outwardly directed radial pressure against the interior surface of the tube anchoring the tube within the tube sheet. An unexpanded land remains between the two expanded regions corresponding to an axially incompressible spacer that separates the expanders. Next, the hydraulic mandrel, which has seals that define the ends of a pressure zone, is inserted in the tube and positioned so that both seals engage unexpanded portions of the tube, one of these unexpanded portions being the land.

Abstract: A high pressure hydraulic tool such as a tube swaging apparatus having a lengthwise-flexible, hollow metallic delivery conduit extending from a hydraulic pressure source to an adaptor. The conduit has an outer diameter of less than about one-eighth inch and an inner diameter of from about 0.01 inch to about 0.05 inch, the conduit being fabricated from a metal having a tensile strength sufficiently great that the tube will not fail when pressurized to at least about 30,000 psi. Swivelable connectors join the lengthwise-flexible conduit to the hydraulic pressure source and to the adaptor, so that the hydraulic source may be connected readily to a succession of tubes to be swaged.
