It has long been assumed that new product innovations are typically developed by product manufacturers, an assumption that has inevitably had a major impact on innovation-related research and activities ranging from how firms organize their research and development to how governments measure innovation. In this synthesis of his seminal research, von Hippel challenges that basic assumption and demonstrates that innovation occurs in different places in different industries. Presenting a series of studies showing that end-users, material suppliers, and others are the typical sources of innovation in some fields, von Hippel explores why this variation in the "functional" sources of innovation occurs and how it might be predicted. He also proposes and tests some implications of replacing a manufacturer-as-innovator assumption with a view of the innovation process as predictably distributed across users, manufacturers, and suppliers. Innovation, he argues, will take place where there is greatest economic benefit to the innovator.

Advances in Small Animal Total Joint Replacement provides an up-to-date, comprehensive examination of joint replacement in veterinary surgery. Part of the Advances in Veterinary Surgery series copublished with the ACVS Foundation, the book presents an evidence-based, multi-system examination of the current state of hip, knee, and elbow replacement in dogs and cats, including information on biomechanics and biomaterials not found in other sources. Written by an international group of experts, the book offers guidance on the history, indications, contraindications, clinical procedures, and a review of the current literature for these surgical techniques. Focusing on replacement of the hip, knee, and elbow, the book also covers disc, shoulder, carpus, and tarsus replacement, as well as information on the development of custom prostheses. Each section incorporates information on potential complications and outcomes assessment. Advances in Small Animal Total Joint Replacement is an unparalleled repository of information for veterinary surgeons, residents, and practitioners with an interest in these procedures.

Using a totally new approach, this groundbreaking book establishesthe logical connections between metallurgy, materials modeling, andnumerical applications. In recognition of the fact that classicalmethods are inadequate when time effects are present, or whencertain types of multiaxial loads are applied, the new, physicallybased state variable method has evolved to meet these needs.Inelastic Deformation of Metals is the first comprehensivepresentation of this new technology in book form. It developsphysically based, numerically efficient, and accurate methods forpredicting the inelastic response of metals under a variety ofloading and environmental conditions. More specifically, Inelastic Deformation of Metals: * Demonstrates how to use the metallurgical information to developmaterial models for structural simulations and low cyclic fatiguepredictions. It presents the key features of classical and statevariable modeling, describes the different types of models andtheir attributes, and provides methods for developing models forspecial situations. This book's innovative approach covers such newtopics as multiaxial loading, thermomechanical loading, and singlecrystal superalloys. * Provides comparisons between data and theory to help the readermake meaningful judgments about the value and accuracy of aparticular model and to instill an understanding of how metalsrespond in real service environments. * Analyzes the numerical methods associated with nonlinearconstitutive modeling, including time independent, time dependentnumerical procedures, time integration schemes, inversiontechniques, and sub-incrementing. Inelastic Deformation of Metals is designed to give theprofessional engineer and advanced student new and expandedknowledge of metals and modeling that will lead to more accuratejudgments and more efficient designs. In contrast to existing plasticity books, which discuss few if anycorrelations between data and models, this breakthrough volumeshows engineers and advanced students how materials and modelsactually do behave in real service environments. As greater demandsare placed on technology, the need for more meaningful judgmentsand more efficient designs increases dramatically. Incorporatingthe state variable approach, Inelastic Deformation of Metals: * Provides an overview of a wide variety of metal responsecharacteristics for rate dependent and rate independent loadingconditions * Shows the correlations between the mechanical response propertiesand the deformation mechanisms, and describes how to use thisinformation in constitutive modeling * Presents different modeling options and discusses the usefulnessand limitations of each modeling approach, with material parametersfor each model * Offers numerous examples of material response and correlationwith model predictions for many alloys * Shows how to implement nonlinear material models in stand-aloneconstitutive model codes and finite element codes An innovative, comprehensive, and essential book, InelasticDeformation of Metals will help practicing engineers and advancedstudents in mechanical, aerospace, civil, and metallurgicalengineering increase their professional skills in the moderntechnological environment.
