Single and two-phase flows are ubiquitous in most natural process and engineering systems. Examples of systems or process include, packed bed reactors, either single phase or multiphase, absorber and adsorber separation columns, filter beds, plate heat exchangers, flow of viscoelastic fluids in polymer systems, or the enhanced recovery of oil, among others.
In each case the flow plays a central role in determining the system or process behavior and performance. A better understanding of the underlying physical phenomena and the ability to describe the phenomena properly are both crucial to improving design, operation and control processes involving the flow of fluids, ensuring that they will be more efficient and cost effective. Expanding disciplines such as microfluidics and the simulation of complex flow physical systems, such as blood flow in physiological networks, also rely heavily on accurate predictions of fluid flow.
Recent advances either in computational and experimental techniques are improving the existing knowledge of single and multiphase flows in engineering and physical systems of interest. This ebook is a review on the state-of-the-art and recent advances in critical areas of fluid mechanics and transport phenomena with respect to chemical and biomedical engineering applications.

I joined NEC in 1968 and was assigned to the circuit development department of the computer division. My first work was the circuit design of the switching mode power supply (SMPS) for the mainframe of the computer system. My job area was expanded to development of the design rule and to standardization of all over the electric and electronics parts for the non-logic circuit. Non-logic circuit was categorized to except the gate-array which forms the logic circuit of the mainframe. The experiment of SMPS was considered to be dangerousness and no one wanted to design. Therefore, my development of the power supply system (PSS) including the circuit design of SMPS was continued. The electric current of the mainframe and the supercomputer was reached to several thousand amperes. The critical problem of PSS was the heat dissipation and the electromagnetic interference (EMI) against the logic circuit. In 1992, the full-scale R&D of EMC became necessary hastily. I was nominated and transferred to the chief managing researcher of the established EMC engineering center in NEC Laboratories. I had believed that the switching mode circuit (SMC) including the digital circuit and SMPS circuit will be improved greatly if the EMC problem is solved. However the deep R&D was difficult because the actual fruits in every year were required strongly. Therefore, his knowledge of the science concerning EMC was not deepened enough. However I could understand the actual status of technologies of the electronics and electrics widely and the basic knowledge about how to approach the science as well as R&D could be learned. During this time, I completed PhD course and received the PhD. degree from Kyushu University, lectured in Kyushu University and Tohoku University for one year each, and executed several national projects by the cooperation of his colleague in NEC and of the supporters in the industrial society and academia. These are considered to be my best harvest in NEC Laboratories. I had decided to continue R&D for solving EMC problem of SMC after his retirement and to try the commercialization of the fruit of R&D. I established ICAST which is the abbreviation of the innovative circuit and system technologies in 2005. The solitary electromagnetic (SEMW) theory was advocated and the novel technologies including the low impedance lossy line (LILL) and the matched impedance lossy line (MILL) were invented based on the SEMW theory.
Two purposes exist in this eBook. The first is to be validated the SEMW theory by the academia and the industrial society. The second is the contribution to the growth of the industry in the world by the technologies of LILL and MILL.

Recent advances in science and technology such as online monitoring techniques, coupling of various processing methods, surface characterization and measurement techniques have greatly promoted the development of ultraprecise machining technology. This precision now falls into the micrometer and nanometer range - hence the name micro & nanomachining technology (MNT).
Machining is a complex phenomenon associated with a variety of different mechanical, physical, and chemical processes.
Common principles defining control mechanisms such as O Jamie de geometry, Newton mechanics, Macroscopic Thermodynamics and Electromagnetics are not applicable to phenomena occurring at the nanometer scale whereas quantum effects, wave characteristics and the microscopic fluctuation become the dominant factors. A remarkable enhancement in computational capability through advanced computer hardware and high performance computation techniques (parallel computation) has enabled researchers to employ large scale parallel numerical simulations to investigate micro & nanomachining technologies and gain insights into related processes.
Micro and Nanomachining Technology - Size, Model and Complex Mechanism introduces readers to the basics of micro & nanomachining (MNT) technology and covers some of the above techniques including molecular dynamics and finite element simulations, as well as complexity property and multiscale MNT methods.
This book meets the growing need of Masters students or Ph.D. students studying nanotechnology, mechanical engineering or materials engineering, allowing them to understand the design and process issues associated with precision machine tools and the fabrication of precision components.

This e-book focuses on the vibrational and nonlinear aspects of plate and shell structure dynamics by applying the finite element model. Specifically, shell finite elements employed in the computational studies included in this book are the mixed formulation based lower order flat triangular shell finite elements. Topics in the book are covered over nine chapters, including the theoretical background for the vibration analysis of plates and shells, vibration analysis of plate structures, shells with single curvature, shells with double curvatures, and box structures (single-cell and double-cell) and the theoretical development for the nonlinear dynamic analysis of plate and shell structures. In addition to presenting the steps in the derivations of the consistent element stiffness and mass matrices, constitutive relations of elastic materials and elasto-plastic materials with isotropic strain hardening, yield criterion, return mapping, configuration and stress updating strategies, and numerical algorithms are presented and discussed. The book is a suitable reference for advanced undergraduates and post-graduate level engineering students, research engineers, and scientists working in the field of applied physics and engineering.

In rehabilitation medicine, the therapeutic application of vibration energy in specific clinical treatments and in sport rehabilitation is being affirmed by a growing number of medical professionals. Clinical applications of mechanical vibrations exist in a variety of forms: mechanical vibrations, ultrasound therapy, extracorporeal shock waves therapy and Extremely Low Frequency (ELF) magnetic field therapy, for example. Each mode of therapy has a specific mechanism of action, dose and indication. However, the enormous potential of vibrations as therapy (understood as ESWT, mechanical vibration, ultrasounds, ELF) have yet to be explored in depth in both the experimental and in the clinical setting. The Mechanical Vibration: Therapeutic Effects and Applications is a monograph that presents basic information about vibrational therapy and its clinical applications. Readers will find information about the mathematical, physical and biomolecular models that make the foundation of vibrational therapy, applied mechanical vibrations in different form (whole body, ultrasound and extracorporeal shock waves) as well as an update on vibrational therapy in general.
This monograph is a useful resource for medical professionals and researchers seeking information about the basics of vibrational therapy.

In the modern era of manufacturing, unconventional machining methods are quite popular due to various advantages such as high accuracy, excellent surface finish, less tool wear, much quieter operations, among others. Moreover, new age and novel materials are sometimes hard to machine with traditional machining processes due to their high strength and brittleness.
Advances in Nonconventional Machining Processes covers recent development in such methods. Chapters have been contributed by many authors and provide detailed information about machining processes (ultrasonic machining, thermally enhanced machining and electronic discharge machining, to name a few). Additional chapters that provide information about novel materials and their fabrication as well as innovations in machining methods (including the use of machine learning techniques) which have long been established on an industrial scale are also included in the book.
Advances in Nonconventional Machining Processes is a reference work suitable for apprentices and academic scholars studying manufacturing. Industry professionals who wish to know about cutting-edge developments in machining techniques will also find this a useful handbook for their library.
