AbstractThis paper examines the quality of transmission of voice over cellular, packet-switched TDMA networks. The medium access mechanism in the uplink is simulated for different statistical multiplexing scenarios in order to assess the effect of front-end clipping on voice quality. Moreover, the simulation is implemented in a real-time demonstration platform utilized to acquire subjective indicators of voice quality by performing Mean Opinion Score (MOS) tests. The results from the MOS tests are reported. Furthermore, an analysis of the obtained speech samples is presented.

This paper considers a specific aspect of a practice-as-research project—the Kingston University Big Read. It explores how to achieve optimum attractiveness and perceived value among students and staff for a free book circulated for the purposes of a pre-arrival shared reading scheme. After consideration of the academic literature relating to the distribution of free books and the theft of books, there follows a detailed examination of marketing practice in the publishing industry relating to the dissemination of free and promotional items through collaborative endeavours. The solutions adopted are described, along with the outcomes perceived in the market, and recommendations are made for the future.
