An enormous number of online resources available on the internet are being used by authors in report writing. Instead of paraphrasing with proper references and citations, some writers opt for shortcuts to generate new documents from documents already published on the internet, by using word spinning software. Some of these word spinning tools are known to be capable of evading plagiarism checks. For this reason, some argue that there would not be any legal obligation related to plagiarism in word spun reports. However, ethical and quality issues of such documents cannot simply be disregarded. Despite an apparent lack of literature published on this issue, this paper includes a comprehensive analysis of different views related to ethicality and plagiarism, from published articles and user forums. The present paper is based upon a study conducted on the assignments submitted by the students at Waiariki Institute of Technology. This research was also focussed on examining both the quality of sentences and the degree of plagiarism of documents created by using a number of word spinners available on the internet. The plagiary of word spun documents was tested using Turnitin software. The quality of each sentence from a number of word spun documents created by a number of word spinners was categorised as 'improved', lowered', or 'distorted' and then analysed using QSR NVivo10 software. The findings of this research indicate significant quality degradation in the word spun documents and total evasion of plagiarism checks.

This chapter discusses the use of peer-to-peer overlay networks to route around failures and congestion points in the Internet. The motivation for this type of overlay network is that often the network layer takes considerable time to react to link failure and is typically not capable of avoiding congestion. For instance, it has been reported that link failure may take the BGP system more than fifteen minutes to react. As a result, the services going over these links suffer from lost connectivity or severe quality degradation in the case of congestion. One technique to solve this problem is to use overlay routing techniques to detect these problems and to route around the problematic link(s). In this chapter we elaborate on the overall architecture of such a system. The concept is introduced and the architecture and implementation of prototype components implementing the behavior is discussed. Subsequently it is described how the overlay topology can be managed dynamically to achieve the same performance as a full mesh topology with a number of overlay edges that scales linearly with the number of nodes in the network.

The EIGER project proposes a global approach for the exploitation of the efficient joint use of Global Navigation Satellite System (GNSS) signals and Ultra-Wide Band (UWB) positioning in order to allow permanent and reliable outdoor/indoor localization. This paper is focused on the UWB positioning subsystem designed within the project. The architecture of the subsystem, design of its components and the transmission scheme leading to the time difference of arrival determination are described. Results of system laboratory tests are presented and discussed.
