Data from sensor networks via the smart hospital framework is comprised of three main layers: data, insight and access. Medical data is collected in real-time from an array of intelligent devices/systems deployed within the hospital. This data offers insight from the analytics or machine learning software that is accessible to healthcare staff via a smartphone or mobile device to facilitate swifter decisions and greater efficiency. Sensor Networks for Smart Hospitals, together with companion volume Advanced Sensors for Smart Healthcare, shows how the use of sensors to gather data on a patient's condition and the environment in which their care takes place can allow healthcare professionals to monitor their well-being and make informed decisions about their treatment. Written by experts in the field, Sensor Networks for Smart Hospitals is an invaluable resource for researchers and healthcare practitioners in their drive to use technology to improve the lives of patients.

Spherical Nanoindentation Stress-Strain Curves

  • 1st Edition
  • January 1, 2025
  • Surya R. Kalidindi + 1 more
  • English
Spherical Nanoindentation Stress-Strain Curves: Applications, Protocols and Data Analysis brings to light the recent advancements in data analysis protocols that have transformed indentation from being used merely as a qualitative tool for comparing materials to its more rigorous application for analyzing the stress-strain characteristics of materials. This book collects and presents all of the important details of the key protocols, many of them recently developed, for the convenience of engineers and scientists in the materials manufacturing industry, OEMs, research laboratories, and academic institutions. Authors Kalidindi and Pathak explain the protocols used in generating indentation stress-strain curves and extracting meaningful properties from measured load-displacement data in spherical nanoindentation, also demystifying the use of nanoindentation as a material characterization tool that provides robust quantitative assessment of a material’s mechanical properties. Materials covered ranges from metals to biomaterials, and includes the use of new data analysis protocols to establish estimates of mechanical properties from the initial loading segment in the indentation experiments, the potential of characterizing the samples with indentation in conjunction with other structure quantification, techniques used to establish novel protocols for extracting new information needed to formulate material, constitutive laws at the lower length scales, the combined use of orientation imaging microscopy (OIM) and nanoindentation, the combined use of Raman spectroscopy and nanoindentation on bio-samples, and new insights into the buckling response in dense carbon nanotube (CNT) brushes.

Elastic Yarns and Textiles

  • 1st Edition

  • English
Elasticity is the ability of a material to be stretched under tensile load and to return to its original starting position on recovery. It is one of the most important properties of textiles and has a direct effect on their functionality. It is elasticity that makes it possible to open up different areas of application through special and mass-produced products, especially in the areas of stretch and compression. About 80% of all clothing textiles produced today, as well as almost all medical textiles, contain special elastic yarns that enable or reinforce elasticity. This edited work describes and explains the production of elastic textiles from raw material to fiber and yarn, processing, and application. Environmental aspects (e.g. recycling) are also explained. Expert contributions from industry and research present the state of the art and practical new developments in such a way that users from industry and trade can use them in line with market requirements. In addition, trainees and students as well as textile experts are addressed.

Curing of Rubber

  • 1st Edition

  • English
This book is for those who are interested in rubber crosslinking. The process of networking formation (initiation, network formation, state of cure, rate of crosslinking, activation energy) is described for the different crosslinking systems. Detailed information about the chemical procedure is provided for each type of curing system. As in industrial practice, sulfur crosslinking takes up most of the description. At each type of curing system, the role of the rubber, the influence of filler, antioxidants, and plasticizer is given in detailed form. The crosslinking of rubber is the essential step in the production of entropy elastic elastomers. The process of crosslinking and the test procedures are described in detail. The induction period, the reaction rate, and the energy of activation are given and it is described how it is used for simulation non-isothermal crosslinking processes. Sulfur and accelerator, peroxides, and co-agents and reactive resins are the predominant topics of the book. The different accelerator classes, sulfur/accelerator ratios, combination of different accelerators, and the role of zinc oxide in initiation and reversion are discussed in detail. Retarders and anti-reversion agents are presented. The other crosslinked systems are presented in detail. The role of the rubber, as a reaction partner, and the achieved crosslinking efficiency are always taken into account. The mechanisms of networking are presented according to current knowledge. Dynamic vulcanization is given a separate chapter because of the practical application of thermoplastic elastomers. The chemical chapters are followed by an overview of the vulcanization processes. Finally, there is a chapter that deals with devulcanization fumes and the N-nitrosamines

Polymer Extrusion

  • 1st Edition

  • English
Plastics extrusion is one of the most important industrial processes wordwide. Over past decades, understanding of extrusion technologies has advanced by the global research efforts, but, due to the fact that the metal barrel hinders direct visualizations to be made by the naked eye, the "true" dynamic processing characteristics of extrusion processes remain unclear. Analytical attempts have thus been carried out either by indirect, static empirical approaches or theoretical mathematical analyses. None of them offer a realistic depiction of what takes place inside the barrel during an extrusion process. As such, the barrel can be considered as a "black-box". This book reveal the “true” dynamic extrusion processing characteristics, accumulated from years of research experience based on the novel visualization technique developed by Professor Zhu of the Beijing University of Chemical Technology. The qualitative discussions within provide not only insight into the scientific aspects of the subject, but also information of practical significance for those in the industry who need to perform process and hardware designs and optimizations. Included are conventional mathematical representations of the single- and twin-screw extrusion technologies. This provides a comprehensive foundation for undergraduate courses in, e.g., plastics processing engineering. Other topics covered are specifically selected to provide a comprehensive technical background and market trend to readers at all levels. Emphasis on the current status and future potential of sustainable and biodegradable polymers will also form part of the discussions.

Mined Individuals in Large Networks presents an overview of one century of research analyzing the growth of networks in our individualist societies, including methods from computer science to address questions within social sciences. The book shows how, with huge data sets, it is possible to gather vast amounts of information on individuals from large scale and social networks. At stake is the ability for the citizens to keep a grip on the social changes evolving around networking. The public concern about massive online surveillance shows the need for tools and methods that would not be only in the hands of some powerful happy few. Now that social network analysis is done by more computer scientists than social scientists, it is essential to remember the social implications of algorithms when they are applied to human beings.
