Circadian rhythms are known to be important drivers of human activity and the recent availability of electronic records of human behaviour has provided fine-grained data of temporal patterns of activity on a large scale. Further, questionnaire studies have identified important individual differences in circadian rhythms, with people broadly categorised into morning-like or evening-like individu...

A sometimes annoying problem in the most internationally widespread cellular telephone system, the GSM system, is an interfering signal generated by the switching nature of TDMA cellular telephone system. A humming noise originating from the speech frames, equivalent to 160 samples of data corresponding to 20 ms at 8 kHz sampling rate is sometimes clearly audible. This paper describes a study o...

In this paper we study how a reduction of consumer switching costs may affect market competition in the wireless telecommunication industry. The reduction of switching costs can be achieved through the implementation of a regulatory policy called Wireless Number Portability (WNP) that allows consumers to retain the same phone numbers when they switch service providers. By r educing consumers' s...
