Название: Nanogenerators and Self-Powered Systems Автор: Bhaskar Dudem, Vivekananthan Venkateswaran, Arunkumar Chandrasekhar Издательство: ITexLi Год: 2023 Язык: английский Формат: pdf (true) Размер: 16.8 MB
This publication aims at providing a thorough overview of the latest research efforts by international authors on nanotechnology and nanomaterials and opening new possible research paths for further novel developments. This volume is a collection of reviewed and relevant research chapters, offering a comprehensive overview of recent developments in the field of nanotechnology and nanomaterials. The book comprises single chapters authored by various researchers and edited by an expert active in harnessing the ubiquitously available biomechanical energies to power portable electronics research area. All chapters are complete in themselves but united under a common research study topic. Photovoltaics usually produce low voltage at their outputs. So, in order to inject their power into utility grids, the output voltage of solar panels should be increased to grid voltage level. Usually, the boost DC-DC converters will be connected between solar panels and grid-connected inverters to boost the panels’ output voltage to more than 320 V (for 380/220 utilities).

This book investigates the performance analysis and optimization design of parallel manipulators in detail. It discusses performance evaluation indices for workspace, kinematic, stiffness, and dynamic performance, single- and multi-objective optimization design methods, and ways to improve optimization design efficiency of parallel manipulators. This book collects the authors’ research results previously scattered in many journals and conference proceedings and presents them in a unified form after the methodical edition. As a result, numerous performance analyses and optimization of parallel manipulators are presented, in which the readers in the robotics community may be greatly interested. More importantly, readers can use the methods and tools introduced in this book to carry out performance evaluation and optimization of parallel manipulators by themselves. The book can provide important reference and guideline for undergraduate and graduate students, engineers, and researchers who are interested in design and application of parallel manipulators.

Название: 3D Printing Advances Автор: Ashutosh Sharma Издательство: ITexLi Год: 2023 Страниц: 417 Язык: английский Формат: pdf (true) Размер: 56.1 MB
This volume presents an overview of various types of advances in 3D printing. It discusses current research trends, problems, and applications of 3D printing processes and materials. It discusses advances in bioprinting, tissue generation, radiotherapy, and safety issues in health care. The book showcases applications of 3D printing in digital design, body part surrogates, rheological models, airway stents, 3D-printed cermets, and more. It also discusses advances in biomimetic nanocomposite materials, intellectual property concerns, and safety issues in 3D printing technology. 3D printing’s rapid technological development is starting to impact the art field because, for the first time, it has become possible to exactly reproduce and reconstruct artworks without any loss of their physical features. Yet, a coherent overview of how 3D printing is used within the art field while paying attention to ethical considerations does not exist. This study will provide an overview of the current developments of 3D printing in the art world, its use, and the direction it is moving toward. Within this study, the technologies that enable, influence, and will continue to affect the 3D reproduction of artworks, namely technologies necessary to capture an artwork’s materials on a chemical and physical level, Artificial Intelligence (AI), 3D printing technology itself, and the rise of the non-fungible token (NFT) are analyzed to be able to understand what 3D printing implies for our changing perception of art in the future.
Название: Integrated Process Planning, Scheduling, and Due-Date Assignment Автор: Halil Ibrahim Demir, Abdullah Hulusi Kokçam, Caner Erden Издательство: CRC Press Год: 2024 Страниц: 153 Язык: английский Формат: pdf (true) Размер: 11.8 MB
Traditionally, the three most important manufacturing functions are process planning, scheduling, and due-date assignment, which are handled sequentially and separately.This book integrates these manufacturing processes and functions to increase global performance along with manufacturing and production cost savings. Integrated Process Planning, Scheduling, and Due-Date Assignment combines the most important manufacturing functions to use manufacturing resources better, reduce production costs, and eliminate bottlenecks with increased production efficiency. The book covers how the integration will help eliminate scheduling conflicts and how to adapt to irregular shop floor disturbances. It also explains how other elements, such as tardiness and earliness, are penalized and how prioritizing helps improve weight performance function. This book will draw the interest of professionals, students, and academicians in process planning, scheduling, and due-date assignment. It could also be supplemental material for manufacturing courses in industrial engineering and manufacturing engineering departments.
