The Development of Social Network Analysis: A Study in the Sociology of Science
TLDR
In this paper, the authors describe the process of centrifugally casting an article such as a tire or the like from a curable or hardenable liquid polymeric material, which process includes the steps of selecting a mold and placing a core within the mold which core is hollow and/or is readily deformable under pressure but which has sufficient memory to resume its original position when the pressure is removed.Abstract:
The process of centrifugally casting an article such as a tire or the like from a curable or hardenable liquid polymeric material, which process includes the steps of selecting a mold and placing a core within the mold which core is hollow and/or is readily deformable under pressure but which has sufficient memory to resume its original position when the pressure is removed. The article being formed is formed between the core and the mold. The space between the core and the mold is filled with the curable liquid material of which the article is to be formed and the hollow core is also filled with a liquid material. The liquid material in the hollow core, the material from which the core is constructed and the curable liquid material all have about the same specific gravity. The mold and core are rotated to centrifugally cast the article which is formed of the curable liquid material. The deformable core permits easy removal from the completed article and the matching of the specific gravities as aforementioned keeps the deformable core from distorting during the centrifugal casting operation. The order of introducing the liquid material into the core, introducing the curable liquid into the space between the mold and core and rotation of the mold and core can be varied within the limits as set forth in the following description. Variations in the structure for accomplishing the principle of matching specific gravities are illustrated and described.read more

Identifying Node Role in Social Network Based on Multiple Indicators
TL;DR: The paper selects the multiple indicators including degree, ego-betweenness centrality and eigenvector centrality to evaluate the importance and the role of a node and shows that the proposed methods perform quite well in evaluating the importance of nodes and in identifying the node role.

Characterization of Delay Propagation in the US Air-Transportation Network
TL;DR: In this paper, the authors analyze flight performance data in 2010 and study the topological structure of the network as well as the aircraft rotation to characterize the properties of flight delays, including the distribution of total delays, dependence on the day of the week and the hour-by-hour evolution within each day.

A New Weighted Degree Centrality Measure: The Application in an Animal Disease Epidemic.
TL;DR: In this paper, the authors proposed weighted degree and strength centrality measures (WDC and WSC) to account for tie weights distribution in weighted heterogeneous networks, where connections are not merely binary entities, but are proportional to the intensity or capacity of connections among the various elements.

Community extraction and visualization in social networks applied to Twitter
TL;DR: The proposed approach for social media analysis, especially for Twitter’s network, relies on a community identification based on a new community detection algorithm called Tribase and an interactive community visualization, which provides gradual knowledge acquisition using the authors' visualization tool, called NLCOMS.
