In the classic rumor spreading model, also known as susceptible-infectedremoved (SIR) model in which rumor spread out of each node proportionally to its degree and all edges have uniform tie strength between nodes. The rumor spread phenomenon is similar as epidemic spread, in which all the informed nodes spread rumor by informing their neighbor nodes. In earlier rumor spreading models, at each ...

Network diversity yields context-dependent benefits that are not yet fully-understood. I elaborate on a recently introduced [1] distinction between tie strength diversity and information source diversity, and explain when, how, and why they matter. The issue whether there are benefits to specialization is the key.

Understanding peer influence in networks is critical to estimating product demand and diffusion, creating effective viral marketing, and designing 'network interventions' to promote positive social change. But several statistical challenges make it difficult to econometrically ...

A small world (SW) is a (large) graph with both local clustering and, on average, short distances between nodes [1,2]. Short distances promote accessibility, whereas local clustering and redundancy of edges, as some research suggests [3,4], promotes robustness to disconnection and, through multiple independent pathways, reliable accessibility as well. For paths to transmit materials and informa...

Steel-reinforced concrete (SRC) columns, which are classified as composite columns, became the most widely used in recent years; because of their extensive advantages over the reinforced concrete and the steel columns. In this paper, the ductility index and its influential factors were explored to investigate the behavior of SRC columns. A straightforward approach was then proposed by establish...

On the basis of test results nine steel-fiber high-strength concrete corbel specimens subjected to a vertical load, influence steel fiber content on shear performance corbels was analyzed. The softened strut-and-tie model (SSTM) used analyze strength corbels, taking into consideration contribution fibers. A calculation for is proposed, and database 26 created by using model. obtained according ...

This article argues that consideration of the strength of ties between communicators can help reconcile disparate results on the impact of new media on social relations. It is argued from the research literature and studies by the author that where ties are strong, communicators can in uence each other to adapt and expand their use of media to support the exchanges important to their tie, but ...

Strut-and-tie is a system of forces' distribution in the form of "load-path" connectivity from the applied load point to the support point. Strut-and-Tie Method (STM) has been developed based on simple truss model. STM models represent the load carrying mechanism of a structural member by approximating the flow of internal forces by means of struts representing the flow of compressive stresses ...
