The monograph is devoted to the construction of the high-order finite difference and finite element methods for numerical solving multidimensional boundary-value problems (BVPs) for different partial differential equations, in particular, linear Helmholtz and wave equations, nonlinear Burgers¿ equations, and elliptic (Schrödinger) equation. Despite of a long history especially in development of the theoretical background of these methods there are open questions in their constructive implementation in numerical solving the multidimensional BVPs having additional requirement on physical parameters or desirable properties of its approximate solutions. Over the last two decades many papers on this topics have been published, in which new constructive approaches to numerically solving the multidimensional BVPs were proposed, and its highly desirable to systematically collect these results. This motivate us to write thus monograph based on our research results obtained in collaboration with the co-authors. Since the topic is importance we believe that this book will be useful to readers, graduate students and researchers interested in the field of computational physics, applied mathematics, numerical analysis and applied sciences

This book provides a summary of the essential knowledge and working processes involved with control of rotating equipment including:machine characteristics;overall control strategies;detailed design; andbest practices.Emphasis is placed on the role of pumps and compressors as part of the overall process flow rather than treating them in isolation as this tends to optimize energy efficiency.Readers are made aware of the critical roles of rotating equipment and are given a good understanding of their dynamic behaviors, including surge/choke. The author imparts the practical know-how and skills involved in the design and implementation of capacity and anti-surge control and safe-guarding logic. Furthermore, the book discusses real-time monitoring of solutions based on operational requirements, dynamic models for control of supply and demand, cause-and-effect relationships, the useof online and offline data, and collaboration with other engineering disciplines. The text facilitates support for the day-to-day operation of in-house open-platform compressor control applications, encouraging the growth of analytic skills in troubleshooting and fixing common problems; it also inculcates a basic understanding of the principles of third-party proprietary technologies and supports decision-making between in-house and third-party solutions.Process engineers working in the oil-and-gas, refining, petrochemical, and chemical industries who bear responsibility for designing control solutions involving pumps and compressors will find this book an invaluable source of practical advice. This book also helps engineers working on design and maintenance of rotating equipment to understand the perspectives and requirements of process control.

This book presents improved numerical techniques and applied computer-aided simulations as a part of emerging trends in mechatronics in all areas related to complex fluids, with particular focus on using a combination of modeling, theory, and simulation to study systems that are complex due to the rheology of fluids (i.e., ceramic pastes, polymer solutions and melts, colloidal suspensions, emulsions, foams, micro-/nanofluids, etc.) and multiphysics phenomena in which the interactions of various effects (thermal, chemical, electric, magnetic, or mechanical) lead to complex dynamics. The areas of applications span materials processing, manufacturing, and biology.

This book presents the fundamental issues related to the real application and behaviour of the VRF system based on the long-term monitoring of the installed system. With our experience of pandemic which COVID-19 is an airborne, the spread of the virus is very fast. With this, the heating, ventilating and air-conditioning (HVAC) system is a major player in the maintenance and control of indoor environment to minimize the spread of the virus. As the variable refrigerant flow (VRF) system is a versatile HVAC system in which it can operate at different conditions, the application of the VRF system is very important to control the indoor environmental conditions. Thus, the publication of this book is important with the present situation and the future possible situation which the control of indoor spaces is very important. With this, this book will serve as a reference for building designer, contractors, building regulators and students.

Fast and Effective Embedded Systems Design, Third Edition is a fast-moving introduction to embedded systems design, applying the innovative Arm mbed "ecosystem," including both hardware components and its web-based development environment. Minimal background knowledge is needed to start. Each chapter introduces a major topic in embedded systems and proceeds as a series of practical experiments. A "learning through doing" strategy is adopted, with the underlying theory being introduced alongside. C/C++ programming is applied, with a step-by-step approach which allows you to get coding quickly. Once the basics are covered, the book progresses to some hot embedded topics - intelligent instrumentation, Bluetooth LE, Zigbee, real-time programming, and the Internet of Things. In this new edition all code is refreshed to match the new mbed operating system, and much new code is introduced. The principles of real-time operating systems are explained, and the capabilities of the mbed RTOS are clearly demonstrated.
