The current global economic downturn and considerable shifting in industrial and manufacturing activities have disturbed the industrial order. However, human work productivity is still one of the most important components of the industrial economy and a determining factor in global competiveness and influence as well as the potential for technological innovation and advancement. Human Work Productivity: A Global Perspective covers how human productivity affects the industrial economy and competitiveness across the industrial and manufacturing sectors. Many approaches that have worked historically must now be reexamined and new approaches must be developed. Integrating recent concepts related to human work productivity for modern production systems/organizations, this book examines how ergonomic improvements for the human operator and/or redesign and rearrangement of the workplace can boost individual productivity. It also covers the impact of the aging workforce, reports on an investigation of total productive maintenance, and considers the efficacy of workplace design from a maintenance perspective. Discussions of work hours and their effect on productivity, the impact of technology, and productivity in a health care organization complete the coverage.In any organization, all components must be considered as an integrated whole for sustained productivity. This book explores these components as independent factors and examines their impact on productivity. It then discusses models integrating these factors, creating a clear understanding of the whole, and details schemes of optimization for putting that understanding into practice.

Muscle strength is an important topic for ergonomics practitioners and physiologists to understand, especially as it relates to workplace injuries. Muscle strength and function is at the heart of many injuries that lead to reduced productivity and economic strain on the worker, the company, and society as a whole.This comprehensive source of information and data relating to muscle strength is the first to present such information in a single source. Muscle Strength explains the general determinants of muscle strength such as gender, age, and muscle type. It illustrates physical data in the context of theoretical background and examines the protocols, techniques, devices, and data used to record muscle strength in various parts of the body. This is followed by a discussion of overexertion, strength prediction, strength and endurance, torque and EMG relationship, and muscle fatigue. Finally, the material is applied to the use of muscle in jobs, to product design, and to studies of job accommodation and the effect of disability on strength.Professionals in ergonomics, biomechanics, sports science, and physiology will find that this unique text provides insight and data on an important subject in their field.

Some specific topics cover algebraic groups and invariant theory, the geometry of homogeneous spaces, representation theory, geometric quantization and symplectic geometry, Lie algebra cohomology, Hamiltonian mechanics, modular forms, Whittaker theory, Toda lattice, and much more.

Electromyography (EMG) is the study of muscle behaviour via electronic means, and is thus a technique fundamental to ergonomics, physiology and biomechanics. This text describes the principles of EMG and its application domains, focusing on anatomy, biology, muscle characteristics, physics, mechanics, EMG signal, noise/artifacts/errors, equipment/devices/techniques, interpretation and computerised data acquisition, and analysis. The book provides a theoretical base, a strategic framework and user experiences.

This is the first monograph to exclusively treat Kac-Moody (K-M) groups, a standard tool in mathematics and mathematical physics, with connections to number theory, combinatorics, topology, singularities, quantum groups, and completely integrable systems. This comprehensive, well-written text moves from K-M Lie algebras to the broader K-M Lie group setting, and focuses on the study of K-M groups and their flag varieties, developing the theory from scratch. Most of the material presented here is not available anywhere in book literature.

Safety or comfort? Can you truly have one without the other? Is it feasible to have both? Although by no means the only factor, a deep understanding of biomechanics plays a leading role in the design of work and workplaces that are both pain and injury free. Standing firmly on the foundation built by the previous edition, the second edition of Biomechanics in Ergonomics establishes an understanding of gross biomechanical loads on the human system at the tissue level and then brings that understanding through to the whole body level.Applications for the Real WorldProduced under the aegis of editor Shrawan Kumar with contributors who are leading scholars in the field, the book contains unique chapters such as Exposure Assessment Tools and Techniques and Cumulative Load and Models. Also included is a chapter on hand tools, which have a real application to the field of ergonomics.New and significantly revamped chapters: Theories of occupational musculoskeletal injury causationAnthropometry and Biomechanics — AnthropometricsMechanical Exposure Assessment in the Design of WorkDeterminant of Muscle StrengthBiomechanics of GlovesThe ACGIH TLV® for Hand Activity LevelWhiplash Injuries — In Vitro StudiesWhiplash Injuries — In Vivo StudiesModels in Manual Materials HandlingRevised NIOSH Lifting EquationWhole Body VibrationCumulative Load and ModelsCreate Safety Through Better Workplace DesignThe book dives deep into the biomechanics of the connective tissues before thoroughly covering upper and lower extremities, shoulder and neck, low back, and whole body mechanics. With chapters selected and designed to provide extensive coverage of ergonomically relevant biomechanics, this volume supplies an integrated understanding of the inseparable relationship between ergonomics and biomechanics that can be translated into better safety design and better workplaces.

Despite the apparently distinct differences between the disciplines of ergonomics and rehabilitation, they deal with the same issues, although at different ends of the spectrum. Keeping this in mind, Ergonomics for Rehabilitation Professionals explores their philosophies and goals, their parallel, divergent, and complementary aspects. It traces the origin of each field and examines the role of ergonomics in rehabilitation. The book begins with a theoretical and conceptual review of ergonomics and its role in rehabilitation. It covers anthropometry and its impact on human biomechanics, allowing readers to grasp complex concepts, visualize what forces are acting where, and understand the consequence of this force. A chapter on tissue mechanics provides an understanding of the effect of the overall load on the tissues and a rationale for possible mechanisms of injury that can be used to design prevention and treatment methods. The book explores the relevant physiological issues, looking at the energy cost of activities and the data on strength and endurance. It discusses whole body biomechanics using an approach that supplies intuitive understanding of the effects of force, gravity, and physiological variables in an integrated manner. Addressing theoretical underpinnings with scientific rigor, the book covers a broad range of topics, always emphasizing design in rehabilitation. The editor’s organization of the material develops concepts in concentric circles with increasing radii, sequencing ideas and exploring them from simple to complex. This selection of topics from two vast and seemingly diverse disciplines provides the tools for setting realistic goals and developing the strategies to achieve them.

In 1988, E. Verlinde gave a remarkable conjectural formula for the dimension of conformal blocks over a smooth curve in terms of representations of affine Lie algebras. Verlinde's formula arose from physical considerations, but it attracted further attention from mathematicians when it was realized that the space of conformal blocks admits an interpretation as the space of generalized theta functions. A proof followed through the work of many mathematicians in the 1990s. This book gives an authoritative treatment of all aspects of this theory. It presents a complete proof of the Verlinde formula and full details of the connection with generalized theta functions, including the construction of the relevant moduli spaces and stacks of G-bundles. Featuring numerous exercises of varying difficulty, guides to the wider literature and short appendices on essential concepts, it will be of interest to senior graduate students and researchers in geometry, representation theory and theoretical physics.

Kac-Moody Lie algebras 9 were introduced in the mid-1960s independently by V. Kac and R. Moody, generalizing the finite-dimensional semisimple Lie alge­ bras which we refer to as the finite case. The theory has undergone tremendous developments in various directions and connections with diverse areas abound, including mathematical physics, so much so that this theory has become a stan­ dard tool in mathematics. A detailed treatment of the Lie algebra aspect of the theory can be found in V. Kac's book [Kac-90l This self-contained work treats the algebro-geometric and the topological aspects of Kac-Moody theory from scratch. The emphasis is on the study of the Kac-Moody groups 9 and their flag varieties XY, including their detailed construction, and their applications to the representation theory of g. In the finite case, 9 is nothing but a semisimple Y simply-connected algebraic group and X is the flag variety 9 /Py for a parabolic subgroup p y C g.
