This brief presents information on occupational injuries from electric shock and arc flash events through a review of literature, electrical incident data, and similar sources. It includes pertinent information such as the nature of the incident, adherence to safety requirements, use of appropriate personal protective equipment (PPE), and extent of injury. Chapters address arc flash and shock hazards, and the need for empirical incident data on the actual hazards that may be experienced when equipment faults or adverse electrical events occur. Certain tasks where the risk of an arc flash or shock hazard may be lower, such as normal operation of properly installed and maintained equipment, may not require the use of any special PPE. Some of this risk reduction is based on anecdotal data, and the brief details why future research challenges will need more empirical incident data on the actual hazards and associated injuries that may be experienced when equipment faults or adverse electrical events occur. Designed for professionals and researchers in fire protection engineering, workplace electrical tasks, or workplace safety, this brief offers a thorough overview of the trends in electrical injuries and the costs related to those injuries.
Chebyshev polynomials crop up in virtually every area of numerical analysis, and they hold particular importance in recent advances in subjects such as orthogonal polynomials, polynomial approximation, numerical integration, and spectral methods. Yet no book dedicated to Chebyshev polynomials has been published since 1990, and even that work focuse
This book, which has only one very distant forerunner authored by David A. Hills with David Nowell, represents a very big step that is the quantification of these problems and represents the twenty-five years’ worth of work which have gone on at Oxford since the first book on the subject. Fatigue (popularly ‘metal fatigue’) is the primary failure mode of all machines, engines, transmissions and indeed almost all mechanical devices. The propagation of cracks is well understood and is treated in the subject Fracture Mechanics. By contrast, the nucleation of cracks is very hard to quantify and this remains the case with so-called ‘free initiation’ and, to a lesser extent, at cracks nucleated from stress raising features. But the third form of nucleation, where cracks start from the edges of rubbing components, that is, at joints, is potentially a very much better-defined environment, and therefore, the problem is amendable to attack by applied mechanics and experiment. The contents are of value both to those embarking on research on the subject and to practitioner in industry.
The third edition of Fire Department Incident Safety Officer has been thoroughly updated to cover the latest trends, information, and best-practices needed by current and aspiring Incident Safety Officers (ISO’s). Developed in partnership with the Fire Department Safety Officer’s Association and based on the 2015 Edition of NFPA 1521, Standard for Fire Department Safety Officer Professional Qualifications, this authoritative resource focuses uniquely on the roles, responsibilities, and duties for fire service officers assigned to the incident command staff position of safety officer. From smoke reading to alternative energy sources to green construction buildings, Fire Department Incident Safety Officer, Third Edition is loaded with up-to-date information needed to keep fire department members safe, including: A new chapter dedicated to the Incident Safety Officer at Training Drills and Special Events Entire chapters devoted to important topics like reading smoke, reading buildings,

Ricci flow is a powerful technique using a heat-type equation to deform Riemannian metrics on manifolds to better metrics in the search for geometric decompositions. With the fourth part of their volume on techniques and applications of the theory, the authors discuss long-time solutions of the Ricci flow and related topics. In dimension 3, Perelman completed Hamilton's program to prove Thurston's geometrization conjecture. In higher dimensions the Ricci flow has remarkable properties, which indicates its usefulness to understand relations between the geometry and topology of manifolds. This book discusses recent developments on gradient Ricci solitons, which model the singularities developing under the Ricci flow. In the shrinking case there is a surprising rigidity which suggests the likelihood of a well-developed structure theory. A broader class of solutions is ancient solutions; the authors discuss the beautiful classification in dimension 2. In higher dimensions they consider both ancient and singular Type I solutions, which must have shrinking gradient Ricci soliton models. Next, Hamilton's theory of 3-dimensional nonsingular solutions is presented, following his original work. Historically, this theory initially connected the Ricci flow to the geometrization conjecture. From a dynamical point of view, one is interested in the stability of the Ricci flow. The authors discuss what is known about this basic problem. Finally, they consider the degenerate neckpinch singularity from both the numerical and theoretical perspectives. This book makes advanced material accessible to researchers and graduate students who are interested in the Ricci flow and geometric evolution equations and who have a knowledge of the fundamentals of the Ricci flow.
