Blockchain technology is making its inception with various platforms in terms of proprietary and open sources community. Irrespective of proprietary or open-source, a blockchain platform primarily built to satisfy the following development criteria: A first criterion is that a blockchain platform consists of a database that is transactional and working. It ensures users access in peer to peer at any point in time [9].A second criterion is that a blockchain platform consists of user identification labels that enable transactions between active users.A third criterion is the platform must verify transactions ahead of its approval. It means that the platform must have a control mechanism to stop transactions that are not validated.

Firstly, we filtered the original data by focussing on the user who makes more interactions in the microblogging service, so called “active users”, finding that “active users” generate the majority interaction in the Sina Microblog. Then, we analysed the relationship between the influence and users’ value of NRTi/NTi, finding that the influential users are exactly more likely to be very influential, but the normal users’ influences are much smaller than influential users. Finally, we selected the minimum effective distance of user as one’s connection in the net graph of Sina Microblog, which is used to display the clear structure of the social network. Through the net graph we can see the relationship between users more clearly. We found the influential user usually occupies the centre location of a small network of whole graph, meaning that the top user can deliver the information to others easier and faster.
Mobile Broadcasting Using WiMAX: A Technology Overview
Published in Amitabh Kumar, Mobile Broadcasting with WiMAX: Principles, Technology, and Applications, 2014
The data-only evolutions, paralleling the HSDPA, are represented in the EV-DO technologies. These technologies are being standardized under the 3GPP2 Forum. The 1x EV-DO is based on the use of one carrier of 1.25 MHz for data only use. The 1x EV-DO networks achieve high throughputs with a 1.25 MHz bandwidth by using advanced modulation and RF technology. This includes, first, an adaptive modulation system, which allows the radio node to increase its transmission rate based on the feedback from the mobile. It also uses advanced “turbo-coding” and multilevel modulation which acts to increase the data rates at the PHY layer. It also uses macro-diversity via a sector selection process and a feature called multi-user diversity. The multi-user diversity permits a more efficient sharing of resources among the active users. Using these techniques, it is possible to achieve data rates of 4.9 Mbps in a 1.25 MHz carrier.
What Works in Facebook Content Versus Relational Communication: A Study of their Effectiveness in the Context of Museums

Hollebeek et al., (2014) proposed that engagement represents a multi-dimensional concept comprising cognitive, emotional, and behavioral dimensions. In the context of SNS, previous research has focused on the behavioral dimension and has shown that engagement is manifested in different behaviors (Bonsón & Ratkai, 2013; Gummerus et al., 2012): clicking, liking, commenting, and sharing behaviors. Yet, measuring organizations’ communication performance in SNS and level of user engagement is by no means an easy task. In fact, measuring ROI (Return on Investment) in SNS is a controversial issue (Fisher, 2009). Fisher (2009) indicated that it is not merely a question of traditional attributes (page views), but about engagement with customers, level of social interaction (buzz, opinions, voices and experiences that people are sharing about a brand). Peters, Yubo, Andreas, Björn, and Koen (2013) advocated appropriate metrics which connect marketing actions and outcomes. In this line, Hoffman and Fodor (2010) also pointed out that metrics for social media should respond to the key social media objectives. They thus propose different metrics for measuring three objectives: awareness, engagement, and Word of Mouth (WOM). Some awareness indicators are the number of fans, installs of applications, impressions, or reviews. Some engagement indicators are the number of comments, active users, user-generated content, or rate activity. WOM indicators include the number of reposts/shares, number of posts on wall, and responses to friend referral invites. Other researchers (Bonsón & Ratkai, 2013; Su, Reynolds, & Sun, 2015) have also proposed measuring three dimensions of consumer engagement in Facebook: popularity (likes), commitment (comments), and virality (shares). In line with these approaches, we propose measuring the communication effectiveness of Facebook fan pages in museums through three consumer engagement dimensions: popularity, generated content, and virality.
