It is generally accepted that the term space weather refers to the time-variable conditions in the space environment that may effect space-borne or ground based technological systems and, in the worst case, endanger human health or life. Therefore there are social and economic aspects of this type of research: one tries to avoid consequences of space weather events by system design or efficient warning and prediction. During the last few years space weather activities have expanded world-wide. Space weather affects spacecrafts as well as ground based systems. The main cause for space weather effects is our Sun. It emits a continuous stream of particles which is called the solar wind. The solar wind is variable. It is modulated by the well known 11 year solar activity cycle. Another source of space weather effects are micrometeorites and other space debris.

I have to admit that I don't even care about the origin of the practice, about the lineage, titles or whatever - I'm only interested if when I applied a teaching and practice in my life - do I get the desired results - and I guarantee if you apply the information from this book, if you engage in the practices described, you will notice wonderful results - in terms of increased xxxual magnetism, increased energy for healing, rejuvenation and spiritual growth (yes, yes, yes - you may even get rid of some wrinkles), and of course, more fabulous sx.

Excel is by far the most widely distributed data analysis software but few users are aware of its full powers. Advanced Excel For Scientific Data Analysis takes off from where most books dealing with scientific applications of excel end. It focuses on three areas-least squares, Fourier transformation, and digital simulation-and illustrates these with extensive examples, often taken from the literature. It also includes and describes a number of sample macros and functions to facilitate common data analysis tasks. These macros and functions are provided in uncompiled, computer-readable, easily modifiable form; readers can therefore use them as starting points for making their own personalized data analysis tools. Detailed descriptions and sample applications of standard and specialized uses of least squares for fitting data to a variety of functions, including resolving multi-component spectra; standard processes such as calibration curves and extrapolation; custom macros for general "error" propagation, standard deviations of Solver results, weighted or equidistant least squares, Gram-Schmidt orthogonalization, Fourier transformation, convolution and deconvolution, time-frequency analysis, and data mapping. There are also worked examples showing how to use centering, the covariance matrix, imprecision contours, and Wiener filtering and custom functions for bisections, Lagrange interpolation, Euler and Runge-Kutta integration.

OECD member countries understand the need to better address the challenges arising from misuse of the Internet. The “Future of the Internet Economy” project was initially presented to the OECD Committee on Consumer Policy (CCP) at its October 2005 and March 2006 meetings, with an invitation to the countries to participate. Recognising the close synergies with its past and future work programme in relation to this issue, the CCP, at its 72nd session in October 2006, agreed to provide input to the project. Cyber fraud was identified as the main theme to be examined, with a particular focus on ID theft; mobile commerce; user education and empowerment; cross-border law enforcement co-operation; and redress for individual victims on line.

Both deregulation in the electrical supply industry and the creation of new electricity markets present electric utility companies with the challenge of becoming more efficient without compromising quality of service. Providing new solutions for this newly deregulated paradigm, Power Quality: VAR Compensation in Power Systems presents comprehensive coverage of power quality, harmonics, and static var compensators in one single volume. The book explains how to ensure that power quality is not affected by the harmonics generated by power electronic equipment and explains how to reduce labor costs and increase reliability of supply by employing a single pole autoreclosing scheme. It also addresses how to analyze frequency response of current transformers and voltage transformers while measuring harmonics. Based on the authors’ extensive experience in the electric supply industry, Power Quality enables engineers to meet the demands of increased loads, strengthen their transmission systems, and ensure reliable electric supply.

This Handbook represents contributions from most of the world’s leading educators and active research experts working in the area of Digital Image and Video Processing. Such a volume comes at a very appropriate time, since finding and applying improved methods for the acquisition, compression, analysis, and manipulation of visual information in digital format has become a focal point of the ongoing revolution in information, communication and computing. Moreover, with the advent of the world-wide web and digital wireless technology, digital image and video processing will continue to capture a significant share of “high technology” research and development in the future. This Handbook is intended to serve as the basic reference point on image and video processing, both for those just entering the field as well as seasoned engineers, computer scientists, and applied scientists that are developing tomorrow’s image and video products and services.

This workbook is a revision to the workbook of the same title first published in 1967. Although Gaussian modeling has limitations, much of the air quality simulation modeling being done today to estimate impact of proposed sources in response to regulatory requirements is Gaussian. The intent of the workbook is 1) to provide an introduction to the bases for dispersion calculations and to dispersion modeling to those that need a starting point in this subject area, and 2) to provide a ready reference to dispersion equations and example calculations for air quality professionals already familiar with dispersion.

We have written this book for those of you who have some experience in project management and are looking for a quick and efficient way to manage your projects. When combined, Excel 2007 and Microsoft Office SharePoint Server (MOSS)—two components of the Office 2007 initiative that Microsoft has developed—are great for managing all phases of a project, creating templates, collaborating on planning processes, tracking project progress, and sharing information with all interested parties. The project management field has grown exponentially over the last decade. Run a query on your favorite job-hunting site and you’ll see that project management experience is a requirement (or at a minimum, a desired skill set) for tens of thousands of job postings. In addition, many of you have upwards of half a dozen to a dozen independent projects running at the same time. This book will show you how to organize the management of those projects using templates we’ve built for Excel 2007 and how to take advantage of the power of SharePoint to communicate and share that information with team members and stakeholders. If you find that this topic interests you and project management seems like a career worth pursuing, we strongly recommend that you consider obtaining your Project Management Professional (PMP) certification through the Project Management Institute (PMI). PMI is the de facto standard in project management methodologies. You will find that many organizations now require a PMP certification for positions related to project management.

This text derives initially from the notes for the course on Analog Electronics given to students taking the MSc courses in Electronics and Microelectronics in the Department of Electronics and Computer Science of the University of Southampton. These are students normally with a first degree in an allied subject such as Mathematics, Physics or Electrical Engineering. As such, a feature is the coverage of a large amount of material in a relatively short space, hopefully good value for money! With the material much the same as for the Analog component of the three-year undergraduate course in Electronic Engineering, the book has been expanded to suit this readership also, in particular Chapter 1 on Basic Circuit Techniques. With some of the material given to research chemists and to undergraduates taking the Physics-with-Electronics, and Chemistry-with-Electronics courses, the interests of the experimental scientist have also been covered. With all of the above courses including laboratory work, that given in the final exercises section of most chapters is thoroughly 'road tested'. All of the numeric calculations have been checked, by hand with the calculator, and by simple BASIC programs.
