In the past few decades, a Technological revolution has occurred that has changed the way we live in dramatic ways. This Technological revolution is the result of the emergence and evolution of a wide variety of new wireless networking tech- nologies. Now people using these technologies are able to access the network and control many applications at will with their handheld devices anywhere, anytime. Although these technologies have made a long lasting impact in the revolution, it has also opened up various challenging issues which are yet to be resolved to make them more efficient and cost-effective.

Since the advent of optical communications, a great Technological effort has been devoted to the exploitation of the huge bandwidth of optical fibers. Start- ing from a few Mb/s single channel systems, a fast and constant Technological development has led to the actual 10 Gb/s per channel dense wavelength di- vision multiplexing (DWDM) systems, with dozens of channels on a single fiber. Transmitters and receivers are now ready for 40 Gb/s, whereas hundreds of channels can be simultaneously amplified by optical amplifiers.

Without doubt, the age of information communications is upon 11s. The rapid pace of Technological advancement in digital data communications can be wit- nessed in a multitude of applications in our day-to-day existence. In recent years, the widespread proliferation of wireless digital cornmunications hass been readily accepted by the general population worldwide; this is nearly unpa~rallcled in few other human scientific achievements in terms of scope and speed of devel- opment.

Communication has been one of the deepest needs of the human race throughout recorded history. It is essential to forming social unions, to educating the young, and to expressing a myriad of emotions and needs. Good communication is central to a civilized society. The various communication disciplines in engineering have the purpose of providing Technological aids to human communication. One could view the smoke signals and drum rolls of primitive societies as being Technological aids to communication, but communication technology as we view it today became important with telegraphy, then telephony, then video, then computer communication, and today the amazing mixture of all of these in inexpensive, small portable devices.

As we enter the next millennium, there are clear Technological patterns. First, the electronic industry continues to scale microelectronic structures to achieve faster devices, new devices, or more per unit area. Secondly, electrostatic charge, electrostatic discharge (ESD), electrical overstress (EOS) and electromagnetic emissions (EMI) continue to be a threat to these scaled structures. This dichotomy presents a dilemma for the scaling of semiconductor technologies and a future threat to new technologies. Technological advancements, material changes, design techniques, and simulation can fend off this growing concern – but to maintain this ever-threatening challenge, one must continue to establish research and education in this issue.

Recent advancements in nanotechnology (NT) materials and growth of micro/ nanotechnology have opened the door for potential applications of microelectro- mechanical systems (MEMS)- and NT-based sensors and devices. Such sensors and devices are best suited for communications, medical diagnosis, commercial, military, aerospace, and satellite applications. This book comes at a time when the future and well-being of Western industrial nations in the twenty-first century’s global eco- nomy increasingly depend on the quality and depth of the Technological innovations they can commercialize at a rapid pace.

It has been over a decade since the Chinese publication of Line Loss in Electric Power Systems. To keep pace with Technological developments, I started a revision as early as 2002, following the main principles that the theoretical framework and characteristics of the first edition should be retained, with new contents added according to new problems after the reform of electric power systems and the new requirements for line loss management practices and in combination with practical experience.
