RFID and the Internet of Things
RFID (Radio Frequency Identification) technology allows for automatic identification of information contained in a tag by scanning and interrogation using radio frequency (RF) waves. An RFID tag contains an antenna and a microchip that allows it to transmit and receive. This technology is a possible alternative to the use of barcodes, which are frequently inadequate in the face of rapid growth in the scale and complexity of just-in-time inventory requirements, regional and international trade, and emerging new methods of trade based on it. Use of RFID tags will likely eventually become as widespread as barcodes today. This book describes the technologies used for implementation of RFID: from hardware, communication protocols, cryptography, to applications (including electronic product codes, or EPC) and middleware. The five parts of this book will provide the reader with a detailed description of all the elements that make up a RFID system today, including hot topics such as the privacy concerns, and the Internet of Things.

Physical Properties of Concrete and Concrete Constituents
Understanding the rheological properties of fresh concrete, the hydration phenomenon of cement responsible for structuration, the relationship between the characteristics of the porous solid obtained and its mechanical performances or resistance to the aggressive penetration requires a complex knowledge of the physicochemistry of reactive porous materials. The development of simple formulation rules therefore requires the assimilation of this knowledge and a good command of the properties of these materials. The purpose of this book is to provide the mix designer with useful knowledge on granular materials and porous materials, which will enable the innovative design of concrete. Topics covered include the characterization of granular materials, the concepts of porosity and specific surface area, and the transport properties (diffusion and permeation) of concrete. Some of these topics are already covered in other general books dedicated to granular or porous materials. The objective here is to bring them together in one book by adapting them for use by concrete specialists. Applications in the form of exercises are offered at the end of each chapter to enable readers to assimilate the theoretical knowledge and to apply such knowledge to concrete problems encountered in civil engineering. Contents 1. Description of Granular Materials, Definitions. 2. Granulometry. 3. Specific Surface Area of Materials. 4. Voids in Granular Materials and the Arrangement of Grains. 5. Voids in Concrete. 6. The Fundamentals of Diffusion. 7. Permeability.

Understanding Distillation Using Column Profile Maps
Researchers share their pioneering graphical method for designing almost any distillation structure Developed by the authors in collaboration with other researchers at the Centre of Material and Process Synthesis, column profile maps (CPMs) enable chemical engineers to design almost any distillation structure using novel graphical techniques. The CPM method offers tremendous advantages over other design methods because it is generalized and not constrained to a particular piece of equipment. Understanding Distillation Using Column Profile Maps enables readers to understand, analyze, and design distillation structures to solve common distillation problems, including distillation by simple columns, side rectifiers and strippers, multiple feed columns, and fully thermally coupled columns. In addition, the book presents advanced topics such as reactive distillation, membrane permeation, and validation of thermodynamic models. For all these processes, the authors set forth easy-to-follow design techniques, solution strategies, and insights gained using CPMs. This book offers everything needed to fully understand and use CPMs as a design tool: Figures help readers understand how to use CPMs as design and optimization tools Examples clearly illustrate how to solve specific problems using CPMs Tutorials allow readers to explore key concepts through experimentation Design and Optimization of Distillation Systems software package, developed for this book, enables readers to reproduce the examples in the book, follow the tutorials, and begin designing their own distillation systems With its many examples and step-by-step tutorials, Understanding Distillation Using Column Profile Maps is recommended for students in chemical engineering in advanced undergraduate and graduate courses. The book also provides new practical techniques that can be immediately applied by chemical engineering professionals in industry.

Microwave Bandpass Filters for Wideband Communications
This book will appeal to scientists and engineers who are concerned with the design of microwave wideband devices and systems. For advanced (ultra)-wideband wireless systems, the necessity and design methodology of wideband filters will be discussed with reference to the inherent limitation in fractional bandwidth of classical bandpass filters. Besides the detailed working principles, a large number of design examples are demonstrated, which can be easily followed and modified by the readers to achieve their own desired specifications. Therefore, this book is of interest not only to students and researchers from academia, but also to design engineers in industry. With the help of complete design procedures and tabulated design parameters, even those with little filter design experience, will find this book to be a useful design guideline and reference, which can free them from tedious computer-aided full-wave electromagnetic simulations. Among different design proposals, wideband bandpass filters based on the multi-mode resonator have demonstrated many unparalleled attractive features, including a simple design methodology, compact size, low loss and good linearity in the wide passband, enhanced out-of-band rejection, and easy integration with other circuits/antennas. A conventional bandpass filter works under single dominant resonant modes of a few cascaded transmission line resonators and its operating bandwidth is widened via enhanced coupling between the adjacent resonators. However, this traditional approach needs an extremely high coupling degree of coupled-lines while producing a narrow upper stopband between the dominant and harmonic bands. As a sequence, the desired dominant passband is restricted to an extent less than 60% in fractional bandwidth. To circumvent these issues and break with the tradition, a filter based on the multiple resonant modes was initially introduced in 2000 by the first author of this book. Based on this novel concept, a new class of wideband filters with fractional bandwidths larger than 60% has been successfully developed so far. This book, presents and characterizes a variety of multi-mode resonators with stepped-impedance or loaded-stub configurations using the matured transmission line theory for development of advanced microwave wideband filters.
