  • Power quality has become an important issue in recent times when many utilities around the world find very difficult to meet energy demands which leads to load shedding and power quality problems. This book on power quality written by experts in their fields will be of great benefit to professionals, engineers and researchers. This book comprises of 16 chapters which are arranged in two sections. Section one covers power quality monitoring, classification, and analysis aspects.

  • In practice, consumption devices are not only resistive but also reactive and this reactance varies with time. Therefore, grid voltage is not stable and coefficients always change in spite of using Automatic Reactive Power Regulator. To regulate voltage and cosφ in an expected range, it is necessary to change the parameters of regulators as the loads change.

  • Although inelastic scattering of light from molecules, a phenomenon now known as Raman scattering, was observed by C. V. Raman in 1928, the nonlinear phenomenon of stimulated Raman scattering was not demonstrated until 1962. Soon after low-loss silica fibers became available around 1970, Roger Stolen and coworkers used stimulated Raman scattering in such fibers not only for amplification of optical signals but also for constructing fiber-based Raman lasers.

  • In addition to the results prepared in accordance with generally accepted accounting principles ("GAAP"), the company uses adjusted EBITDA, a non-GAAP financial measure, in analyzing and assessing the overall performance of the business. The company defines adjusted EBITDA as loss from continuing operations before income taxes, interest income and expense, depreciation and amortization, stock based compensation, restructuring expense, acquisition and integration expenses and certain other non-cash income and expense items.

  • Power amplifiers consist of an active device, biasing networks and input and output reactive filtering and transforming networks. These networks are effectively bandpass filters offering the required impedance transformation. They are also designed to offer some frequency shaping to compensate for the roll-off in the active device frequency response if broadband operation is required. However the function of each network is quite different. The input circuit usually provides impedance matching to achieve low input return loss and good power transfer. ...

  • As argued throughout the previous chapters the book, mobile propagation channels exhibit of time-variant propagation properties [ 131. Although apart from simple cordless telephone schemes most mobile radio systems employ power control for mitigating the effects of received power fluctuations, rapid channel quality fluctuations cannot be compensated by practical, finite reaction-time power control schemes.

  • Bertrand and Mullainathan (1998) illustrate the potential power of designs that consider interactions across governance mechanisms. They examine the impact on executive compensation of changes in states’ anti-takeover legislation. Adoption of anti-takeover legislation presumably reduces pressure on top managers. They attempt to distinguish between optimal contracting and skimming theories in explaining observed contracting arrangements.

  • This book began as a study of Japanese public policy, more specifically the legal, ethical, and political dimensions of health policy debates in Japan. Having studied medico-legal conflicts in the United States, and the tensions they generated between public health and individual rights, state power and personal privacy, medical paternalism and patients’ rights, I decided to examine how such concerns were addressed in Japan with regard to AIDS policy and the definition of death.

  • The return on a nominal bond can be decomposed into two components: a real rate of return and a compensation for the erosion of purchasing power arising from inflation. For conventional government nominal zero coupon bonds, such as those in the example above, the nominal return is certain (provided it is held to maturity) but the real return is not (because inflation is uncertain). An index-linked zero coupon bond would have its value linked to movements in a suitable price index to prevent inflation eroding its purchasing power (so its ‘real value’ is protected).

  • The compensation or return theoretically due to or actually gained by a country’s citizens when a country’s resources such as oil or forests are exploited for export has always depended on complex social institutions, property rights and power relations. In an era of increasing trade, investment and financial liberalisation, the relationship between the exploitation of resources and the accrual of benefits to poor citizens is even more difficult.

  • In general, there are no great surprises in the coefficients on the control variables. The strongest finding is the powerful negative relation between firm size and firm volatility, a result which is well known. Additionally, we find a strong positive relation between the value of CEO stock and option holdings and firm volatility. This result is somewhat surprising, in that we might expect that the risk aversion of executives would cause those with greater firm holdings to reduce firm volatility.
