Christian Hafner – författare

Presenting innovative, promising and unconventional techniques, Post-modern Electromagnetics outlines the essential tools for the creation of numerical methods. Hafner offers a comparative analysis of the fundamental computational electromagnetics methods and proposes future adaptive strategies. Complementary to Max-1: A Visual Electromagnetics Platform, this unique text challenges current thinking and provides guidance through the solution of practical problems. Features Include:* Outline of Maxwell theory from simple material properties to complex media and wave equations * Discussion of intelligent optimization strategies such as genetic algorithms designed to improve the performance of existing techniques * Applications section demonstrating solutions in statics, scattering, gratings, antenna, antenna arrays, guided waves, resonators, coupling and waveguide discontinuities * Explanation of the background to numerical methods showing how the various approaches to computational electromagnetics can be generalized and combinedStudents and researchers interested in advanced numerical approaches and design engineers developing new codes for computational electromagnetics will benefit from this exploration of creative electromagnetics solutions.

Beginning with a detailed comparison of "traditional" methods of EM field analysis, this text leads up to a step-by-step explication of the Generalized Multiple Technique (GMT).

Diploma Thesis from the year 2008 in the subject Computer Science - Commercial Information Technology, grade: 1,0, TU Bergakademie Freiberg, language: English, abstract: Changing industry structures and altering rules of competition is why most companies today face a new challenge in creating a competitive advantage. The meaning of Information Technology (IT) has changed from just being available to accelerating and facilitating processes to an integral part of the company's mission and strategy. IT governance is what defines the holistic perspective of how to deal with and use IT, especially in large companies. The objective is to create advantages by aligning IT and corporate strategy in order to create value while minimizing risk and monitoring the performance of IT. Many different frameworks and standards have emerged over the last years, providing processes and control objectives for keeping the company s IT in a value-adding track. However, an important issue seems to be the huge availability of various frameworks. This mostly results in problems concerning the right decision on frameworks to be selected. Implementing efficient IT governance requires using only those processes that cover the individual IT-related issues and problems of a company best, while ignoring unnecessary ones. The use of frameworks is associated with costs and may quickly result in an inefficient use of IT governance. The present thesis addresses this challenge and shall help IT decision makers to decide on an efficient framework or set of frameworks. In order to do so, a model analyzes the fit between discovered IT-related problems and various existing publicly available frameworks. Different surveys and market analyses will be used for identifying possible IT-related problems. The creation of problem-clusters will help to determine the most efficient framework by measuring the coverage of processes by different frameworks. As a result, this thesis will provide an approach to avoid processes that may not be necessary while covering important ones for an efficient use of IT governance frameworks.
