Recent estimates hypothesize that the US will need $1.6 trillion dollars for the rehabilitation, replacement, and maintenance of existing infrastructure systems within the next 20 years. Presenting a new vision and way of designing and managing the civil infrastructure of the nation, Intelligent Infrastructure: Neural Networks, Wavelets, and Chaos Theory for Intelligent Transportation Systems and Smart Structures presents the foundations of intelligent infrastructure. It presents novel technologies, methods, and detailed computational algorithms for creation of smart structures and intelligent freeways.This book crosses the two disciplines of structural engineering and transportation engineering and provides a unique treatise for attacking and solving some of the most complex and intractable problems encountered in the emerging fields of smart structures and intelligent transportation systems. It demonstrates how some of these problems can be solved effectively through ingenious integration of several different computing paradigms including chaos theory (based on nonlinear dynamics theory), wavelets (a signal processing method), and three complementary soft computing methods: fuzzy logic, neural networks, and genetic algorithms.Adeli and Jiang discuss multidisciplinary methodologies for health and monitoring and nonlinear active control of tall building structure subject to dynamic loading such as those due to winds or earthquake. Delineating an approach to infrastructure system engineering and management that is both modern and futuristic, the authors explore the advanced computing technologies that will play an important role in the creation of an effective smart structure technology.

While the weight of a structure constitutes a significant part of the cost, a minimum weight design is not necessarily the minimum cost design. Little attention in structural optimization has been paid to the cost optimization problem, particularly of realistic three-dimensional structures. Cost optimization is becoming a priority in all civil engineering projects, and the concept of Life-Cycle Costing is penetrating design, manufacturing and construction organizations. In this groundbreaking book the authors present novel computational models for cost optimization of large scale, realistic structures, subjected to the actual constraints of commonly used design codes. As the first book on the subject this book: Contains detailed step-by-step algorithmsFocuses on novel computing techniques such as genetic algorithms, fuzzy logic, and parallel computingCovers both Allowable Stress Design (ASD) and Load and Resistance Factor Design (LRFD) codesIncludes realistic design examples covering large-scale, high-rise building structuresPresents computational models that enable substantial cost savings in the design of structures Fully automated structural design and cost optimization is where large-scale design technology is heading, thus Cost Optimization of Structures: Fuzzy Logic, Genetic Algorithms, and Parallel Computing will be of great interest to civil and structural engineers, mechanical engineers, structural design software developers, and architectural engineers involved in the design of structures and life-cycle cost optimisation. It is also a pioneering text for graduate students and researchers working in building design and structural optimization.

This book shows how wavelets can be used to enhance computational intelligence for chaotic and complex pattern recognition problems. By integrating wavelets with other soft computing techniques such as neurocomputing and fuzzy logic, complicated and noisy pattern recognition problems can be solved effectively. The book focuses on applications in intelligent transportation systems (ITS) where a number of very complicated pattern recognition problems have eluded researchers over the past few decades. Advancing the frontiers of computational intelligence, this book describes ingenious computational models based on novel problem solving and computing techniques such as case-based reasoning, neurocomputing, and wavelets, and presents examples to illustrate their importance and use. It presents a multi-paradigm intelligent systems approach to the freeway traffic incident detection and construction work zone management problems. And it advocates application and integration of wavelets, neural networks and fuzzy logic for modeling the complex traffic flow behaviors leading to effective and efficient control and management solutions. It also presents efficient, reliable, and robust algorithms for automatic detection of incidents on freeways. "Wavelets in Intelligent Transportation Systems" is an invaluable resource for computational intelligence researchers and transportation engineers involved in the application of advanced computational techniques for ITS.

Networking of personal computers and workstations is becoming commonplace in academic and industrial environments. A cluster of workstations provides engineers with a familiar, cost-effective environment for high performance computing. However, workstations often have no dedicated link and communicate slowly on a local area network (LAN), such as the Ethernet. Thus, to effectively harness the parallel processing or distributed computing capabilities of workstations, new algorithms need to be developed with a higher computation-to-communication ratio. Distributed Computer-Aided Engineering presents distributed algorithms for three fundamental areas: finite element analysis, design optimization, and visualization - providing a new direction in high performance structural engineering computing.

Based on the authors’ groundbreaking research, Automated EEG-Based Diagnosis of Neurological Disorders: Inventing the Future of Neurology presents a research ideology, a novel multi-paradigm methodology, and advanced computational models for the automated EEG-based diagnosis of neurological disorders. It is based on the ingenious integration of three different computing technologies and problem-solving paradigms: neural networks, wavelets, and chaos theory. The book also includes three introductory chapters that familiarize readers with these three distinct paradigms. After extensive research and the discovery of relevant mathematical markers, the authors present a methodology for epilepsy diagnosis and seizure detection that offers an exceptional accuracy rate of 96 percent. They examine technology that has the potential to impact and transform neurology practice in a significant way. They also include some preliminary results towards EEG-based diagnosis of Alzheimer’s disease. The methodology presented in the book is especially versatile and can be adapted and applied for the diagnosis of other brain disorders. The senior author is currently extending the new technology to diagnosis of ADHD and autism. A second contribution made by the book is its presentation and advancement of Spiking Neural Networks as the seminal foundation of a more realistic and plausible third generation neural network.

Wavelet-Based Vibration Control of Smart Buildings and Bridges
Earthquakes, bridge collapses, and other natural disasters have dominated news coverage in the last few years. Aging infrastructure needs to be rehabilitated and new infrastructure needs to be designed differently. Presenting a highly innovative, modern approach verging on the futuristic, Wavelet-Based Vibration Control of Smart Buildings and Bridges discusses a new generation of building and bridge structures that not only withstands [generation is singular] the destructive effects of nature but is also impact and explosion resistant.Based on the groundbreaking work of Hojit Adeli, the book introduces the new mathematical concept of wavelets into the field of structural vibration control. It presents a new control algorithm for robust control of smart civil structures subjected to destructive environmental forces, such as earthquakes and wind. It then discusses a new hybrid control system, the hybrid tuned liquid column damper (TLCD) system. The new hybrid control system, which combines passive and semi-active control systems, is intended to achieve increased reliability and maximum operability of the control system during power failure and to eliminate the need for a larger power requirement.The great majority of papers published in this area of active structural vibration control deal with small or academic problems. The models in this book have been tested and their effectiveness evaluated extensively on small problems for the sake of comparison with other methods and results reported in the literature. The authors go one step further and apply them to realistic and large building and bridge structures to demonstrate the applicability of the new smart technology to large real-world civil structures. Balancing coverage between theory and application, the book demonstrates the benefits of the new smart technology in the design of structures that are safer and more sustainable.

Die Einstellung der muslimischen und der nicht-muslimischen Wohnbevölkerung in Deutschland zum Terrorismus
Die Diplomarbeit hat sich zum Ziel gesetzt anhand einer eigenen quantitativen Befragung von Muslimen und Nicht-Muslimen herauszufinden, ob die Haupthypothese, dass Muslime den islam-extremistischen Terrorismus weniger ablehnen, sich bewahrheitet.Dabei mache ich haupts chlich folgende Ursachen f r die unterschiedliche Bewertung des Terrorismus verantwortlich: Wahrnehmung von Eigen- und Fremdgruppe, Unterschiedliche Normen- und Werte durch subkultur- oder kontrakultur hnliche Verh ltnisse, strukturelle und soziale Desintegration, Identit tskrise, die eine innere Zerrissenheit ausl st, Minderwertigkeitsgef hle, ausgel st durch die eigene Positionswahrnehmung in der Gesellschaft, Abwehrmechanismen zur Bek mpfung der eigenen Frustration undMinderwertigkeitsgef hle, Wahrnehmung von sozialen Ungleichheiten und sozialer Ungerechtigkeit und die Medienbeeinflussung.Die Auffassung der vergangenen Jahre, dass Muslime den islam-extremistischen Terrorismus moralisch unterst tzen, kann daher nur in einer Gruppe untersucht werden, die einheitlich aus Muslimen besteht. Bislang gab es Teile der Gesellschaft, die den Generalverdacht gegen ber den Muslimen unterst tzten oder ablehnten, doch keiner in Deutschland erforschte bis jetzt dieses Ph nomen. Um nicht nur das wiederzugeben, wor ber sich viele Experten einig sind, soll durch die Koppelung von Theorie und Empirie herausgefunden werden, ob einige Theorien zur Einstellung zum Terrorismus auch empirisch nachweisbar sind. Die Stichproben sind wegen ihrer geringen Gr e nur in der Lage, Trends aufzuzeigen und k nnen nicht repr sentativ sein.Um die Trennung der nicht-muslimischen und muslimischen Befragten zu erreichen, gab es zwei Frageb gen: einen f r die muslimische Wohnbev lkerung und einen f r die nicht-muslimische Wohnbev lkerung. Bevor ein Fragebogen ausgeh ndigt wurde, musstendie Befragten angeben, ob sie Muslim oder Nicht-Muslim sind. Beide Frageb gen sind zum gr ten Teil standardisiert.Der Fragebogen beinhaltet u.a. f
