  • Modelling and computations in electromagnetics is a quite fast-growing research area. The recent interest in this field is caused by the increased demand for designing complex microwave components, modeling electromagnetic materials, and rapid increase in computational power for calculation of complex electromagnetic problems. The first part of this book is devoted to the advances in the analysis techniques such as method of moments, finite-difference time- domain method, boundary perturbation theory, Fourier analysis, mode-matching method, and analysis based on circuit theory....

  • Wavelets in Boundary Integral Equations Numerical treatment of integral equations can be found in classic books [1, 2]. In this chapter the integral equations obtained from field analysis of electromagnetic wave scattering, radiating, and guiding problems are solved by the wavelet expansion method [3–7]. The integral equations are converted into a system of linear algebraic equations. The subsectional bases, namely the pulses or piecewise sinusoidal (PWS) modes, are replaced by a set of orthogonal wavelets.

  • Although much of its discovery process is descriptive and qualitative, chemistry is fundamentally a quantitative science. It serves a wide range of human needs, activities, and concerns. The mathematical sciences provide the language for quantitative science, and this language is growing in many directions as computational science in general continues its rapid expansion. A timely opportunity now exists to strengthen and increase the beneficial impacts of chemistry by enhancing the interaction between chemistry and the mathematical sciences.

  • If the initial target is set as a result of competitive tendering, then the employer may feel some assurance that he is obtaining ‘value for money’. But if the target is negotiated or later has to be varied, then the employer may feel that the contractor’s knowledge of his intended methods and costs may enable him to add a margin in the target estimate to safeguard his position. This means that it is improbable that the target cost will ever be lower than the contractor’s privately estimated bottom line price....

  • Of course, credit expansion for reasons beyond economic merit might for a while help increasing economic growth. If credit expansion works toward the extension of productive capacity, this process might go on for an extended period of time, even if borrowers in the long run will not be able to pay back their loan. The downside in this case is the accumulation of non-performing loans in the banking sector which in the end might lead to high fiscal cost. This might actually be what has been observed in China: One could argue that a non-trivial part of the loans by...

  • One of the main tasks of economics is to explode the basic in- flationary fallacy that confused the thinking ofauthors and statesmen from the days ofJohn Law down to those of Lord Keynes. There cannot be any question of monetary reconstruction and economic recovery as long as such fables as that of the blessings of 'expansion- ism' form an integral part ofofficial doctrine and guide the economic policies of the nations. None of the arguments that economics advances against the inflationist and expansionist doctrine is likely to impress demagogues.

  • Empirical models for money holdings are applied for two purposes. First, they are used to guide the analysis of monetary developments, as a means of quantifying the contribution of various economic determinants to money growth in order to provide a deeper understanding of the causes of money growth. This is necessary in order to develop a view of underlying monetary expansion. Second, the models provide a normative framework to assess whether the stock of money in the economy is consistent with price stability and to interpret the nature of deviations from this norm.

  • Voluntary carbon offsets have been traded in relatively small volumes and on a demonstration basis since the late 1980s. Some organizations, such as the Climate Trust in Oregon, have many years of experience in purchasing and retiring offsets on behalf of clients or customers (the Climate Trust was established in 1997 to assist new power plants in Oregon to meet a state regulatory requirement for net CO2 emissions).

  • This paper develops a minimally supervised approach, based on focused distributional sim- ilarity methods and discourse connectives, for identifying of causality relations between events in context. While it has been shown that distributional similarity can help identify- ing causality, we observe that discourse con- nectives and the particular discourse relation they evoke in context provide additional in- formation towards determining causality be- tween events.

  • Zambia’s economic growth slowed to 6.6% in 2011 from 7.6% in 2010, mainly as a result of a weaker mining sector performance. However, the medium-term economic outlook appears favourable, underpinned by sustained expansion in agriculture, construction, manufacturing, transport and communications, and by a rebound in mining. Inflation is projected to remain in single digits, reflecting prudent monetary policy, while the objective of exchange rate policy is to maintain external competitiveness.

  • The Total Suspended Solids (TSS) standard identified in the USEPA Cluster Rules for New Source Performance Standards (NSPS) is the benchmark for existing mills, as Alberta mills currently apply the technology required to achieve this standard. This was based on a review of the current performance values for Alberta mills, other Canadian mills, top performing mills in the U.S., and allows for sufficient flexibility for plant operations during shutdown, start-up and upset conditions. Alberta’s standards for TSS are a monthly average of 4.0 kg/ADt and daily maximum of 8.
