This paper is an analysis of how mediated interaction has changed the ways in which we establish and develop interpersonal relationships. The paper examines the dimensions of friendship and also the attempts to separate out the role of interaction via various media such as mobile telephony, MUDs, MOOs, and IRC. The paper finds that interaction via the Internet may aid the establishment of relat...

Why do adults find it difficult to learn foreign languages? In the research literature, there are a number of hypotheses. Studies on the use of the Internet for learning, however, suggest that a hypothesis that has been largely ignored for the past two decades might have increased validity. The language ego permeability hypothesis argues that adults have difficulty learning foreign languages, b...

In this paper we describe what a desynchronised channel on IRC is. We give procedures on how to create such a channel and how to remove desynchronisation. We explain which types of desynchronisation there are, what properties desynchronised channels have, and which properties can be exploited.

There are three key metrics (end-co-ed delay, packet loss rate and delay variation) for determining the quality of Voice over IP (VoIP). The impact of delay variation can be reduced by de-jitter buffering at a receiver side. The impairment caused by the packet delay and loss can be reduced by routing the traJic through an Internet path with a better quality. However, the current Internet infras...

Giving corrective feedback (CF) is an essential part of the teaching and learning process, and the way it should beneficially be done has been the focus of attention for numerous researchers especially when traditional ways of CF provision are not possible, particularly in rare situations such as outbreaks of diseases. This study investigated how different ways of giving feedback; namely, throu...

In this paper, an interval approach is presented to achieve perfect selectivity and maximum sensitivity in distance relay zones, considering uncertainties. For this purpose, first, the uncertainties affecting the settings of the three zones of a distance relay are discussed. Then, by using the Monte-Carlo simulation, the uncertainties are modelled and the impedances seen by the distance relay a...

To meet the very high data rate requirements for wireless Internet and multimedia services, cooperative systems with multiple antennas have been proposed for future generation wireless systems. In this thesis, we focus on multiple antennas at the source, relay and destination. We study both downlink and uplink cooperative systems with single antenna relays. For downlink systems, the optimal pre...
