This paper argues that the advent of the WWW and the principles now developing for the move ‘social machines’ has posed serious challenges to traditional social theory. In particular, it is argued that the concept of social machines and the forms of distributed agency they imply amplify ‘deep flaws’ in the underlying principles of current agency theories that make empirical work using such fram...

The paper presents the problem of signal degradation in packet-based voice transmission and its influence on the voice recognition correctness. The Internet is evolving into universal communication network which carries all types of traffic including data, video and voice. Among them the Internet telephony, namely VoIP is going to be an application of a great importance and that is why it is so...

Recently the Internet has witnessed the emergence of content distribution networks (CDNs). In this paper we study the problem of optimally replicating objects in CDN servers. In our model, each Internet Autonomous System (AS) is a node with nite storage capacity for replicating objects. The optimization problem is to replicate objects so that when clients fetch objects from the nearest CDN serv...

conclusions: although our study showed the prevalence of internet addiction was not more than other populations and universities, since the prevalence of internet addiction is rapidly increasing worldwide, this population might also be at risk of addiction. thus, focusing on related factors can help us in designing more effective interventions and treatments for this susceptible group. results:...

This paper presents the IPS-I-model: a model that describes the process of information problem solving (IPS) in which the Internet (I) is used to search information. The IPS-I-model is based on three studies, in which students in secondary and (post) higher education were asked to solve information problems, while thinking aloud. In-depth analyses of the thinking-aloud protocols revealed that t...

Consider a private network of geographically dispersed computers with fast and high capacity connections, and an Internet application session, such as a massive multiplayer online game, with a server and a set of clients. We refer to the former as a service overlay network (SON), and assume that it could be connected to the Internet. The problem is to decide how to configure and utilize the SON...

To conduct business on the Internet, many problems should be solved. Examples of these problems are: security, authentication, heterogeneity, interoperability, and ontology problems. The diicult problem here is how to combine disparate information sources to integrate them in an open environment like Internet. Many approaches were invented to solve this problem. We discuss the problem in the do...
