Cengel's Thermodynamics is known to be student friendly, self-instructive, and easy to read and understand even for the most challenging topics with the help of attractive illustrations, examples, and real-world applications. The authors' philosophy is that the best way to learn is by practice. Special effort is made throughout the book to reinforce material that was presented earlier and to appeal to students' natural curiosity and intuition. For instructors looking to engage students and enhance their problem-solving skills, Connect offers student-friendly, accessible content, tools, and resources that develop high-level problem-solving and critical thinking skills, including New Application-Based Activities. Thermodynamics can be defined as the science of energy. Although everybody has a feeling of what energy is, it is difficult to give a precise definition for it. Energy can be viewed as the ability to cause changes. The name thermodynamics stems from the Greek words therme (heat) and dynamis (power), which is most descriptive of the early efforts to convert heat into power. Today the same name is broadly interpreted to include all aspects of energy and energy transformations including power generation, refrigeration, and relationships among the properties of matter.

Nanotechnology in Fuel Cells focuses on the use of nanotechnology in macroscopic and nanosized fuel cells to enhance their performance and lifespan. The book covers the fundamental design concepts and promising applications of nanotechnology-enhanced fuel cells and their advantages over traditional fuel cells in portable devices, including longer shelf life and lower cost. In the case of proton-exchange membrane fuel cells (PEMFCs), nano-membranes could provide 100 times higher conductivity of hydrogen ions in low humidity conditions than traditional membranes. For hydrogen fuel cell, nanocatalysts (Pt hybrid nanoparticles) could provide 12 times higher catalytic activity.

Polymerized nanoparticles and nanofibers can be prepared using various processes, such as chemical synthesis, the electrochemical method, electrospinning, ultrasonic irradiation, hard and soft templates, seeding polymerization, interfacial polymerization, and plasma polymerization. Among these processes, plasma polymerization and aerosol-through-plasma (A-T-P) processes have versatile advantages, especially due to them being "dry", for the deposition of plasma polymer films and carbon-based materials with functional properties suitable for a wide range of applications, such as electronic and optical devices, protective coatings, and biomedical materials. Furthermore, it is well known that plasma polymers are highly cross-linked, pinhole free, branched, insoluble, and adhere well to most substrates. In order to synthesize the polymer films using the plasma processes, therefore, it is very important to increase the density and electron temperature of plasma during plasma polymerization.

The rising share of photovoltaic (PV) energy requires sophisticated digital techniques to control, monitor and integrate them with the grid. For movable systems, tracking is necessary. Digital technologies are defined as electronic tools, a set of technologies, systems, devices and resources that generate, transmit, store or process data. These technologies can be integrated into PV systems to predict, optimize, monitor and control their energy production in the most appropriate and efficient way, for fault detection and diagnosis, as well as for the prediction of PV panel performance, degradation and fatigue failure. Therefore, the main objective of this book is to present relevant works on the integration of digital technologies in PV systems: from general to rural and remote installations. The book focuses on the latest research and developments in remote PV energy system integration. It aims to provide extensive coverage of current research and developmental activities, and new approaches intended to overcome several critical limitations in the use of remote PV systems, such as those connected to grid and water pumps. This using control, monitoring and optimization techniques in the broadest sense, covering the use of new digital technologies such as embedded systems, data connection, Internet of Things, blockchain, cloud computing, Artificial Intelligence and robotics for PV systems through different applications such as MPPT controller, solar tracker, cleaning system, cooling system, water pumping systems, monitoring systems and solar-powered electric vehicles.

This book investigates human-machine systems through the use of case studies such as crankshaft maintenance, liner piston maintenance, and biodiesel blend performance. Through mathematical modelling and using various case studies, the book provides an understanding of how a mathematical modelling approach can assist in working out problems in any industrial-oriented activity. Mathematical Modeling: Simulation Analysis and Industrial Applications details a data analysis approach using mathematical modeling sensitivity. This approach helps in the processing of any type of data and can predict the result so that based on the result, the activity can be controlled by knowing the most influencing variables or parameters involved in the phenomenon. This book helps to solve field and experimental problems of any research activity using a data-based modeling concept to assist in solving any type of problem. Students in Manufacturing, Mechanical, and Industrial Engineering programs will find this book very useful. This topic has continued to advance and incorporate new concepts so that the manufacturing field continues to be a dynamic and exciting field of study.

Modular Multilevel Converters Expert discussions of cutting-edge methods used in MMC control, protection, and fault detection. In Modular Multilevel Converters: Control, Fault Detection, and Protection , a team of distinguished researchers delivers a comprehensive discussion of fault detection, protection, and tolerant control of modular multilevel converters (MMCs) under internal and external faults. Beginning with a description of the configuration of MMCs, their operation principles, modulation schemes, mathematical models, and component design, the authors go on to explore output control, fault detection, capacitor monitoring, and other topics of central importance in the field. The book offers summaries of centralized capacitor voltage-balancing control methods and presents several capacitor monitoring methods, like the direct and sorting-based techniques. It also describes full-bridge and half-bridge submodule-based hybrid MMC protection methods and alternative fault blocking SM-based MMCs.
