This paper presents a new pulse width modulator control method using the offset function to reduce switching loss in five-level Cascade inverter. The proposed technique is based on the offset function being 3rd harmonic voltage. The offset voltage will be added to the control voltages so that the voltage of phase which has absolute of load current largest move into top or bottom of the carriers.

This study provides comparative findings on the impact of adoption of International Financial Reporting Standards (IFRSs) on the value relevance of reported accounting and non-accounting information in a set of six countries with a British accounting heritage but divergent harmonization paths leading up to IFRS adoption. The countries included in the sample are the United Kingdom, Australia, Hong Kong, Singapore, Malaysia and South Africa.

The main object of this surveycum-expository article is to present an overview of some recent developments involving the Riemann Zeta function, which have their roots in the works of the great eighteenth-century Swiss mathematician, Leonhard Euler (1707 1783) and the Russian mathematician, Christian Goldbach (1690 1764).

In this paper we collect two generalizations of harmonic numbers (namely generalized harmonic numbers and hyperharmonic numbers) under one roof. Recursion relations, closed-form evaluations, and generating functions of this unified extension are obtained.

Based on the result of challenge 1, we propose to elaborate a methodology for the harmonization of time series covering ESPON territory at regional level for the period 1995-2006 on the basis of simple indicators of regional policy (population, GDP, unemployment, age structure). The problem is not to cover immediately a great number of indicators but to define a methodology that could be implemented in the ESPON 2013 DB and reproduced by different ESPON projects.

I enjoyed reading this book for a number of reasons. One reason is that it addresses high-speed analog design in the context of microwave issues. This is an advanced level book, which should follow courses in basic circuits and transmission lines. Most analog integrated circuit designers in the past worked on applications at a low enough frequency that microwave issues did not arise. As a consequence, they were adept at lumped parameter circuits and often not comfortable with circuits where waves travel in space.

This paper gives a quantitative version of Thurston’s hyperbolic Dehn surgery theorem. Applications include the first universal bounds on the number of nonhyperbolic Dehn fillings on a cusped hyperbolic 3-manifold, and estimates on the changes in volume and core geodesic length during hyperbolic Dehn filling. The proofs involve the construction of a family of hyperbolic conemanifold structures, using infinitesimal harmonic deformations and analysis of geometric limits.

Although we are well into the fourth decade since the advent of the laser, the number and type of lasers and their wavelength coverage continue to expand. One seeking a photon source is now confronted with an enormous number of possible lasers and laser wavelengths. In addition, various techniques of frequency conversion—harmonic generation, optical parametric oscillation, sum- and difference-frequency mixing, and Raman shifting—can be used to enlarge the spectral coverage.

Virtually every branch of the sciences, engineering, economics, and related fields now discusses or refers to chaos. James Gleick's 1987 book, Chaos: making a new science and a 1988 one-hour television program on chaos aroused many people's curiosity and interest. There are now quite a few books on the subject. Anyone writing yet another book, on any topic, inevitably goes through the routine of justifying it. My justification consists of two reasons
