As such, the book also explores the application of AI technologies, such as vision sensing and machine learning, in GTAW process sensing and feature extraction and monitoring, and presents the state-of-the-art in computer vision, image processing and machine learning to detect welding defects using non-destructive methods in order to improve welding productivity. Featuring the latest research from ORNL (Oak Ridge National Laboratory) using digital image correlation technology, this book will appeal to researchers, scientists and engineers in the field of advanced manufacturing.
Failure of welded components can occur during service as well as during fabrication. Most common, analyses of the resistance of welded components against failure are targeted at crack avoidance. Such evaluations are increasingly carried out by modern weldability studies, i. e. considering interactions between the selected base and filler materials, structural design and welding process. Such weldability investigations are particularly targeted to prevent hot cracking, as one of the most common cracking phenomena occurring during weld fabrication. To provide an international information and discussion platform to combat hot cracking, an international workshop on Hot Cracking Phenomena in Welds has been created, based on an initiative of the Institute for Materials and Joining Technology at the Otto-von-Guericke University in Magdeburg and the Division V. 5 - Safety of Joined Components at the Federal Institute for Materials Research and Testing (BAM) in Berlin, Germany. The first workshop was organized in Berlin under the topics mechanisms and phenomena, metallurgy and materials, modelling and simulations as well as testing and standardization. It consisted of 20 individual contributions from eight countries, which were compiled in a book that found a very ready market, not only in the welding community. As a consequence of increasing interest, it has been decided to establish the Workshop on Hot Cracking Phenomena in Welds as a regular event every three years embedded in the International Institute of Welding (IIW). Attached to the IIW Commission IX and II Spring intermediate meetings, the second workshop was organized in March 2007.

Mathematically rigorous, computationally fast, and easy to use, this new approach to electromagnetic well logging gives the reservoir engineer a new dimension to MWD/LWD interpretation and tool design Almost all publications on borehole electromagnetics deal with idealizations that are not acceptable physically. On the other hand, exact models are only available through detailed finite element or finite difference analysis, and more often than not, simply describe case studies for special applications. In either case, the models are not available for general use and the value of the publications is questionable. This new approach provides a rigorous, fully three-dimensional solution to the general problem, developed over almost two decades by a researcher familiar with practical applications and mathematical modeling. Completely validated against exact solutions and physics-based checks through over a hundred documented examples, the self-contained model (with special built-in matrix solvers and iteration algorithms) with a plain English graphical user interface has been optimized to run extremely fast seconds per run as opposed to minutes and hours and then automatically presents all electric and magnetic field results through integrated three-dimensional color graphics. In addition to state-of-the-art algorithms, basic utility programs are also developed, such as simple dipole methods, Biot-Savart large diameter models, nonlinear phase and amplitude interpolation algorithms, and so on. Incredibly useful to oilfield practitioners, this volume is a must-have for serious professionals in the field, and all the algorithms have undergone a laborious validation process with real use in the field. This groundbreaking new volume contains: * A general three-dimensional electromagnetic model for nondipolar transmitters in layered anisotropic media with dip, developed for MWD/LWD well logging and tool design, offering accurate solutions in seconds as opposed to minutes or hours * An approach that helps readers explore new transmitter and receiver concepts and designs * Information on model steel mandrels, charge radiation from layer interfaces, large coil and thin layer effects, anisotropic media and low resistivity pay, borehole eccentricity and invasion, with a new and powerful model developed from first principles * A new approach that removes physical limitations associated with dipole, integral equation, Born, geometric factor or hybrid techniques and explains how these problems are overcome, building on advances from aerospace computational fluid mechanics * Mathematical and programming details as well as ready-to-use software with integrated three-dimensional color graphics for those needing immediate answers
"In this book, Michael Collins ... demonstrates why he is considered one of the leading researchers in the field of lithic analysis. The work offers a masterful review and synthesis of Clovis blade technology with lucid prose and lavish illustrations.... I recommend this book for all professional and avocational archaeologists interested in Paleoindian occupations of the New World." -- Illinois Archaeology "This book makes an important contribution to a newly revived debate on the significance of the Clovis phenomenon and the timing and migration routes of the peopling of the New World more generally." -- SAS Bulletin Around 11,000 years ago, a Paleoindian culture known to us as "Clovis" occupied much of North America. Considered to be among the continent's earliest human inhabitants, the Clovis peoples were probably nomadic hunters and gatherers whose remaining traces include camp sites and caches of goods stored for utilitarian or ritual purposes. This book offers the first comprehensive study of a little-known aspect of Clovis culture-- stone blade technology. Michael Collins introduces the topic with a close look at the nature of blades and the techniques of their manufacture, followed by a discussion of the full spectrum of Clovis lithic technology and how blade production relates to the production of other stone tools. He then provides a full report of the discovery and examination of fourteen blades found in 1988 in the Keven Davis Cache in Navarro County, Texas. Collins also presents a comparative study of known and presumed Clovis blades from many sites, discusses the Clovis peoples' caching practices, and considers what lithic technology and cachingbehavior can add to our knowledge of Clovis lifeways. These findings will be important reading for both specialists and amateurs who are piecing together the puzzle of the peopling of the Americas, since the manufacture of blades is a trait that Clovis peoples shared with the Upper Paleolithic peoples in Europe and northern Asia.

The fuel consumption of a modern combustion engine is one of the most important purchase criteria in contemporary society. Increasing oil prices and exhaust emissions taxes force the automotive industry to continuously improve the vehicle engines. The fuel consumption is closely related to the frictional losses of an engine. New material pairings or constructive modifications of the piston group can reduce such losses. Another innovative concept to lower the frictional forces is the micro-structuring of thermo-mechanically highly stressed surfaces. Within an interdisciplinary research group sponsored by the German Research Foundation, scientists at the Leibniz Universität Hannover and Universität Kassel have been working together to investigate this research topic. This final report presents their findings and offers scope for further discussion.
Designing Weldments An important tool for professionals wishing to enhance their understanding or those who are new to the subject, Designing Weldments bridges that gap between structural engineers and a deeper understanding of the welding engineering within the structures. In modern-day construction, welding is the primary method to join various members of any structure. Welds are required to meet various types of load in tension, compression, torsion, and perform in static or cyclic loading conditions. The weld has to be at least as strong as the parent metal to meet the demands of various stress working on the structure. It should meet the structural requirement, add value to the integrity of the structure, and prevent failures. However, many design engineers lack even a fundamental insight or a basic understanding of essential welding processes and design requirements. Simply copying a few joint configurations in a drawing will not suffice. All-embracing and readable, Designing Weldments delivers a deeper understanding of many design factors that play a critical role in the design. The book clarifies welding design principles and applications. With this reference in hand, designers will have expert knowledge to consider very early on in the project, the implications of the choice of what type of weld to use for joining structural members, and how the component is made. The author explains the many welding techniques developed over the years, as well as some of which are still evolving. The reader will also find in this book: Rules of thumb for saving time and money in the design phase of a project. An insider's view for choosing the proper welding approach to ensure the overall strength of a structure. Offers structural engineers a deeper understanding of the weld within their structures. Clarifies welding design principles and applications, limiting the necessity to redesign the structure. Audience The intended market for this book is professionals working on the infrastructural projects in shipbuilding, construction of buildings, bridges, offshore platforms, wind towers for renewable energy, and other structures that join plates, pipes, and pipelines in power plants, manufacturing, and repair.

These topics are among the central issues in the investigation and applications of semiconductors and in the operation of semiconductor devices. The authors preface their treatment with an introduction to semiconductor materials and conclude with a chapter on point defect maldistributions. This text is suitable for advanced undergraduate and graduate students in materials science and engineering, and for those studying semiconductor physics.
The approach to the solution within the CRC/TR 96 financed by the German Research Foundation DFG aims at measures that will allow manufacturing accuracy to be maintained under thermally unstable conditions with increased productivity, without an additional demand for energy for tempering. The challenge of research in the CRC/TR 96 derives from the attempt to satisfy the conflicting goals of reducing energy consumption and increasing accuracy and productivity in machining. In the current research performed in 19 subprojects within the scope of the CRC/TR 96, correction and compensation solutions that influence the thermo-elastic machine tool behaviour efficiently and are oriented along the thermo-elastic functional chain are explored and implemented. As part of this general objective, the following issues must be researched and engineered in an interdisciplinary setting and brought together into useful overall solutions:  1. Providing the modelling fundamentals to calculate the heat fluxes and the resulting thermo-elastic deformations in a comprehensive manner, 2. Mapping of the structural variability as a result of the relative movement inside the machine tool, 3. Providing the tools for an efficient adjustment of parameters that vary greatly in time and space by means of parameter identification methods as a prerequisite for correction and compensation solutions, 4. Engineering and demonstrating solutions to control-integrated correction of thermo-elastic errors by an inverse position setpoint compensation of the error at the TCP, 5. Engineering and demonstrating solutions based on the material properties to compensate for thermo-elastic effects through a homogeneous propagation of the temperature field, as well as reducing and smoothing the distribution of heat dissipated in supporting structures, 6. Developing metrological fundamentals to record the thermo-elastic errors in special structural areas of machine tools, 7. Engineering a methodological approach to simultaneous and complex evaluation of the CRC/TR 96 solutions, referring to their impact on product quality, production rate, energy consumption and machine tool costs  Â
