Channel Characterisation and System Design for Sub-Surface Communications By David Gibson
Paperback: List Price: $308.09 $77.02 | You Save: 75%
Prints in 3-5 business days
Based on the author's PhD thesis, this book is a theoretical study of subterranean radio communication, with the focus on methods that depend primarily on the penetration of electromagnetic fields... More > through the ground. Through-the-earth communication using e-m fields - specifically magnetic induction - plays a role in search and rescue systems used in the mining industry. It is also used for borehole telemetry, pipeline location and by cavers and pot-holers. Chapters describe propagation, antennas, and the design of transmitters and receivers. A figure of merit - the specific aperture - is introduced as an aid to antenna design. A crucial aspect of all systems is the signal to noise ratio, for which the strategy of noise-matching is introduced. The design of a wide-band low-frequency sounder is described, for channel evaluation using a non-ideal binary sequence. A method of calculating the inverse of a generalised sequence is described, for which cross-correlation results in a system identification signal.< Less

Woman’s Status & Islam By Sabir Ali Khan Tahirkheli

Some critics are regularly propagating the impression that Islam usurped the rights of women and imposed restrictions on their freedom. This propaganda appears to be serving its purpose and some... More > Muslim women are easily influenced by this misconception. They feel that their rights are less than western women. This is definitely incorrect. Due to above reasons, some Muslim women who are not yet aware of their real rights in Islamic society, stand up and join such negative-sponsored movements. They either voice their demands for freedom equal to western women or start feeling psychological backwardness. This depressive impression has absolutely no basis. Muslim women, in actual sense, have better rights. Some of them are, of course, easily misguided. But if this situation is thoroughly studied, it would transpire that such misguided women alone are not responsible for this state of affairs.< Less
