This book analyzes the thermal characteristics of power electronic devices (PEDs) with a focus on those used in wind and solar energy systems. The authors focus on the devices used in such applications, for example boost converters and inverters under different operating conditions. The book explains in detail finite element modeling techniques, setting up measuring systems, data analysis, and PEDs’ lifetime calculations. It is appropriate reading for graduate students and researchers who focus on the design and reliability of power electronic devices.
This book examines the characteristics of Proton Exchange Membrane (PEM) Fuel Cells with a focus on deriving realistic finite element models. The book also explains in detail how to set up measuring systems, data analysis, and PEM Fuel Cells’ static and dynamic characteristics. Covered in detail are design and operation principles such as polarization phenomenon, thermodynamic analysis, and overall voltage; failure modes and mechanisms such as permanent faults, membrane degradation, and water management; and modelling and numerical simulation including semi-empirical, one-dimensional, two-dimensional, and three-dimensional models. It is appropriate for graduate students, researchers, and engineers who work with the design and reliability of hydrogen fuel cells, in particular proton exchange membrane fuel cells.
The most authoritative publication in nearly fifty years on the subject of conserving paintings on canvas. In 2019, Yale University, with the support of the Getty Foundation, held an international conference, where nearly four hundred attendees from more than twenty countries gathered to discuss a vital topic: how best to conserve paintings on canvas. It was the first major symposium on the subject since 1974, when wax-resin and glue-paste lining reigned as the predominant conservation techniques. Over the past fifty years, such methods, which were often destructive to artworks, have become less widely used in favor of more minimalist approaches to intervention. More recent decades have witn...
This book presents the proceedings of the International Virtual Conference on Industry 4.0 (IVCI4.0 2020). This conference brings together specialists from the academia and industry sectors to promote the exchange of knowledge, ideas, and information on the latest developments and applied technologies in the field of Industry 4.0. The book discusses a wide range of topics such as the design of smart and intelligent products, developments in recent technologies, rapid prototyping and reverse engineering, multistage manufacturing processes, manufacturing automation in the Industry 4.0 model, cloud-based products, and cyber-physical and reconfigurable systems, etc. The volume supports the transfer of vital knowledge to the next generation of academics and practitioners.
Despite the ongoing impact of the COVID-19 pandemic, the challenge of realizing sustainability across the triple bottom line of social, environmental, and economic development remains an urgent priority. If anything, it is now imperative that we work towards achieving the United Nations Sustainable Development Goals (SDGs). However, the global challenges are significant. Many of the societal challenges represent complex problems that require multifaceted solutions drawing on multidisciplinary approaches. Engineering management involves the management of people and projects related to technological or engineering systems—this includes project management, engineering economy and technology m...
E-maintenance is the synthesis of two major trends in today’s society: the growing importance of maintenance as a key technology and the rapid development of information and communication technology. E-maintenance gives the reader an overview of the possibilities offered by new and advanced information and communication technology to achieve efficient maintenance solutions in industry, energy production and transportation, thereby supporting sustainable development in society. Sixteen chapters cover a range of different technologies, such as: new micro sensors, on-line lubrication sensors, smart tags for condition monitoring, wireless communication and smart personal digital assistants. E-...
Digitalisation is becoming a standard practice in the fashion industry. Innovation in digital fashion is not just limited to computer-aided design (CAD) and manufacturing (CAM), rather it runs throughout the fashion supply chain, from product life cycle management and developing new business models that promote sustainability to connecting virtual and augmenting reality (VR/AR) with fashion for enhanced consumers experience through smart solutions. Digital Fashion Innovations: Advances in Design, Simulation, and Industry captures the state-of-art developments taking place in this multi-disciplinary field: Discusses digital fashion design and e-prototyping, including 2D/3D CAD, digital patter...
This textbook explains electricity generation in plain English so non-engineers can easily understand it. It also presents a framework to incorporate sustainability into international development projects in the energy sector. It uses examples from Africa to illustrate both sustainable and unsustainable energy development projects.
To be able to compete successfully both at national and international levels, production systems and equipment must perform at levels not even thinkable a decade ago. Requirements for increased product quality, reduced throughput time and enhanced operating effectiveness within a rapidly changing customer demand environment continue to demand a high maintenance performance. In some cases, maintenance is required to increase operational effectiveness and revenues and customer satisfaction while reducing capital, operating and support costs. This may be the largest challenge facing production enterprises these days. For this, maintenance strategy is required to be aligned with the production l...
