Internet, as a new channel of WOM, enables consumers to get multiply WOM messages. However, there is a very real consumer situation that consumers may receive opposite messages (positive-negative) from the same sources. According to tie strength, this paper divides e-WOM sources into strong tie sources and weak tie sources, examining how e-WOM sources moderate the influence of e-WOM presentatio...

Social networks often provide only a binary perspective on social ties: two individuals are either connected or not. While sometimes external information can be used to infer the strength of social ties, access to such information may be restricted or impractical. Sintos and Tsaparas (KDD 2014) first suggested to infer the strength of social ties from the topology of the network alone, by lever...

Power oscillations are a growing concern among power system operators worldwide. Traditionally, the main countermeasure against dangerous power oscillations has been the installation of power system stabilizers (PSS). Essentially, the potential for inter-area power oscillations depends on the strength of the tie lines between different areas and the load on the ties. From a European perspective...

Understanding the relationships between people in a social network and measuring their strength over time are interesting problems with distinct applications. Here, we propose a new algorithm (STACY) to automatically classify tie strength in eight different classes by considering the temporal aspect. Our results show: such classes represent different behaviors, and STACY identifies strong relat...

We analyze the strength of ties through three different clustering algorithms applied to co-authorship social networks from three different research areas. This study reveals if tie strength metrics can be used to evaluate clusters quality. We obtain different results for each algorithm and observe that Markov cluster algorithm provides the best results for co-authorship social networks. Also, ...

PERFORMANCE CHARACTERIZATION OF HIGH PERFORMANCE CONCRETES UNDER FIRE CONDITIONS By Wasim Khaliq (Advisor: Prof. Venkatesh Kodur) Monday, April 30, 2012, 1:00 pm CEE Conference Room (EB 3546D) In recent years, high performance concretes (HPC) are finding increasing applications in buildings and infrastructure due to numerous advantages, such as higher strength and durability, these HPC offer ov...

It is observed that, reinforced concrete beams failed due to flexure but in case of deep beam failure occur due to shear. Deep beams may be defined as the beam where shear span to depth ratio less than 2. A number of researchers already proposed various approach to predict the ultimate strength of deep beams. In this study a newer approach is developed to calculate the ultimate shear strength o...

We propose a novel cohesive subgraph model called ? -strengthened ( ? , ? ) -core (denoted as -core), which is the first to consider both tie strength and vertex engagement on bipartite graphs . An edge strong if contained in at least butterflies 2 × -bicliques). requires each upper or lower level have ties, given To retrieve vertices of optimally, we construct index I store all -cores. Effecti...
