ocial network analysis (related to network theory) has emerged as a key technique in modern sociology. It has also gained a significant following in anthropology‚ biology‚ communication studies‚ economics‚ geography‚ information science‚ organizational studies‚ social psychology‚ and sociolinguistics‚ and has become a popular topic of speculation and study. People have used the idea of "social network" loosely for over a century to connote complex sets of relationships between members of social

Results Properties of social networks Mean network size was 80.67 (SD = 39.84‚ Mdn = 75)‚ with a range of 10–279 (Figure 1). The shape of the distribution is similar to that found in other studies of social networks (Bernard et al.‚ 1990; Hill & Dunbar‚ 2003). The size of the kin and friend networks is given in Table 1. Multilevel models The results of the two models are presented Table 2. The intraclass correlations (ICCx) of the models were 0.18 for Model 1 and 0.24 for Model 2

wireless network is the best. IP networks form the backbone of worldwide digital networking. They have encouraged the merger of voice‚ data‚ and radio waves‚ which can be digitized into packets and sent via any digital network (Turban‚ Volonino). This convergence is happening on a much more global scale and is changing the way in which people‚ devices‚ and applications communicate (Turban‚ Volonino).

PAPER ON ARTIFICIAL NEURAL NETWORKS ABSTRACT The developments in Artificial Intelligence (AI) appear promising‚ but when applied to real world intelligent task such as in speech‚ vision and natural language processing‚ the AI techniques show their inadequacies and ‘brittleness’ in the sense that they become highly task specific. The computing models inspired by biological neural networks can provide new directions to solve problems arising in natural tasks.

to Network Management Phase 3 Discussion Board Professor Shawn Murray April 25‚ 2012 In comparing Osi models to non-Osi models I chose to discuss the FCAPS model. The acronym FCAPS stands for the five layers it is comprised of; 1. Fault management- network faults or problems are found and fixed. Potential problems are identified and addressed thus preventing them from reoccurring in the future. This minimizes downtime and potential costs. 2. Configuration management- The network is controlled
