Design of Digital Phase Shifters for Multipurpose Communication Systems (River Publishers Series In Communications Ser.)
by Binboga Siddik YarmanDesign of Digital Phase Shifters for Multipurpose Communication Systems aims to cover a new emerging need in designing digital phase shifters for modern communication systems. With the advancement of new generation mobile communication systems, directed beams save a substantial amount of RF-power, and improve the noise immunity. In this regard, beam-forming circuits, namely, digital phase shifters constitute essential parts the antenna arrays. Therefore, this book is devoted to design of digital phase shifters for various communications systems.In the good old days, phase shifter design requirements used to demand narrow bandwidth with no physical size constraints. Nowadays, they must be compact and suitable for Very Large Scale Integrated Circuits (VLSI) or Microwave Monolithic Integrated Circuit (MMIC) implementation with Wide Phase Range (WPR) and Wide Frequency Band (WFB).Since the 1980s, the author has been designing digital phase shifters for various applications. He started to work with loaded lines phase shifters, and then employed branch line couplers to achieve wider frequency bands. In order to reduce the physical size, he used a 3 element Symmetric LC ladder based T or PI configurations. In order to achieve broad frequency band with large phase range, usage of LC lattice structures is inevitable. Lately, the author designed phase shifters using both lowpass and highpass LC ladder and lattice based switched-structures, which are suitable for monolithic implementation. In the course of design, MOS transistors were employed as switching elements. This book includes several novel digital phase shifter topologies, which provides wide phase range and wideband operation.Technical topics discussed in the book include:- Basic Concept of Antenna Arrays- Concept of Digital Phase Bit- Scattering Parameters to analyze the electric performance of phase shifters- Transmission Lines as circuit elements to construct practical phase shifters- Loaded Line Digital Phase Shifters (DPS)- Lowpass Based T/PI Section DPS- Highpass Based T/PI Section DPS- 3-Element LC T/PI Section DPS- Wide Phase Range, Wide Frequency Band Symmetric Lattice Based DPSFor each topology presented, explicit design equations are provided and programs to assess the electric performance of each topology is developed in a MatLab environment. It is expected that the reader will be self-sufficient to design and implement the digital phase shifters topologies presented in this book.
Design of Digital Phase Shifters for Multipurpose Communication Systems
by Binboga Siddik YarmanThis book aims to cover a new emerging need in designing digital phase shifter for modern communication systems. With the advancement of new generation mobile communication systems, directed beams of antenna arrays save a substantial amount of power as well as improve the communication quality. In this regard, beam-forming circuits, such as digital phase shifters (DPS) constitute essential parts of the antenna array systems. Therefore, this book is devoted to the design of digital phase shifters for various communications systems. Nowadays, phase array systems demand compact phase shifters suitable for chip implementation with wide phase-range and broad frequency band. Each chapter of this book is organized as stand-alone in such a way that the reader requires no specific background acquired from the other chapters. For each phase shifter topology introduced in this book, the reader is furnished with explicit design equations to construct the circuit under consideration. Furthermore, design equations are programmed using MATLAB to assess the electrical performance of the phase shifters with ideal and lossy components. MATLAB design programs are given at the and of each chapter as appendices and provided as soft copy on the web page of the book. In chapters 12 and 14, MMIC layouts for the lattice and T-section based DPS are provided for the readers. It is hoped that an interested reader can immediately identifies the “optimum phase shifter topology” for the need under consideration with its estimated electric performance.

Design of Electronic Devices Using Redox-Active Organic Molecules and Their Porous Coordination Networks (Springer Theses)
by Jaejun KimThis book addresses the development of electronic devices using redox-active organic molecules and their porous coordination networks (PCNs), and highlights the importance of the molecular arrangement. Redox-active organic molecules hold considerable promise as flexible electronic elements, because their electronic state can easily be controlled using external energy. Although various kinds of redox-active organic molecules have been synthesized, attempts to apply them to electronic devices have been limited, owing to the lack of proper structural design. Moreover, ligand-based redox-active PCNs remain largely unexplored because of the limited availability of redox-active ligands. In addition to developing new redox-active organic molecules, in order to design electronic devices based on these molecules/PCNs, it is essential to understand the connections between their molecular arrangement, electrical properties, and redox activity. In this thesis, the redox-active organic molecule 2,5,8-tri(4-pyridyl)1,3-diazaphenalene (TPDAP), which features a large pi plane and multi-intermolecular interactivity, is used to develop a resistive switching memory device. In addition, its PCNs are synthesized to fabricate chemiresistive sensors, and the electrical properties are modulated using post-synthetic modification. Each mechanism is systematically investigated by means of structural determination and well-defined control experiments. Subsequently, the book proposes general guidelines for designing electronic devices using redox-active organic molecules. The book will appeal to a broad range of readers, from basic scientists to materials engineers, as well as general, non-expert readers.
Design of Enterprise Systems: Theory, Architecture, and Methods
by Ronald GiachettiIn practice, many different people with backgrounds in many different disciplines contribute to the design of an enterprise. Anyone who makes decisions to change the current enterprise to achieve some preferred structure is considered a designer. What is problematic is how to use the knowledge of separate aspects of the enterprise to achieve a globally optimized enterprise. The synthesis of knowledge from many disciplines to design an enterprise defines the field of enterprise engineering.Because enterprise systems are exceedingly complex, encompassing many independent domains of study, students must first be taught how to think about enterprise systems. Specifically written for advanced and intermediate courses and modules, Design of Enterprise Systems: Theory, Architecture, and Methods takes a system-theoretical perspective of the enterprise. It describes a systematic approach, called the enterprise design method, to design the enterprise. The design method demonstrates the principles, models, methods, and tools needed to design enterprise systems. The author uses the enterprise system design methodology to organize the chapters to mimic the completion of an actual project. Thus, the book details the enterprise engineering process from initial conceptualization of an enterprise to its final design.Pedagogical tools available include:For instructors: PowerPoint® slides for each chapter Project case studies that can be assigned as long-term projects to accompany the text Quiz questions for each chapter Business Process Analyzer software available for download For students: Templates, checklists, forms, and models to support enterprise engineering activities The book fills a need for greater design content in engineering curricula by describing how to design enterprise systems. Inclusion of design is also critical for business students, since they must realize the import their decisions may have on the long-term design of the enterprises they work with. The book’s practical focus and project-based approach coupled with the pedagogical tools gives students the knowledge and skills they need to lead enterprise engineering projects.

Design of Fastenings for Use in Concrete: The CEN/TS 1992-4 Provisions (Beton-Kalender Series)
by Rainer Mallée Rolf EligehausenThe European pre-standard CEN/TS 1992-4 for the design of fastenings by means of headed studs, anchor channels as well as post-installed mechanical and chemical anchors is ready for use. The background and interpretation of the provisions related to the determination of actions and resistances based on limit state design, durability, fire resistance, fatigue and earthquake actions as required by CEN/TS 1992 are described in detail. Selected chapters from the German concrete yearbook are now being published in the new English "Beton-Kalender Series" for the benefit of an international audience. Since it was founded in 1906, the Ernst & Sohn "Beton-Kalender" has been supporting developments in reinforced and prestressed concrete. The aim was to publish a yearbook to reflect progress in "ferro-concrete" structures until - as the book's first editor, Fritz von Emperger (1862-1942), expressed it - the "tempestuous development" in this form of construction came to an end. However, the "Beton-Kalender" quickly became the chosen work of reference for civil and structural engineers, and apart from the years 1945-1950 has been published annually ever since.

Design of High Strength Steel Reinforced Concrete Columns: A Eurocode 4 Approach
by Sing-Ping Chiew Yanqing CaiThis book is the companion volume to Design Examples for High Strength Steel Reinforced Concrete Columns – A Eurocode 4 Approach. Guidance is much needed on the design of high strength steel reinforced concrete (SRC) columns beyond the remit of Eurocode 4. Given the much narrower range of permitted concrete and steel material strengths in comparison to EC2 and EC3, and the better ductility and buckling resistance of SRC columns compared to steel or reinforced concrete, there is a clear need for design beyond the guidelines. This book looks at the design of SRC columns using high strength concrete, high strength structural steel and high strength reinforcing steel materials – columns with concrete cylinder strength up to 90 N/mm2, yield strength of structural steel up to 690 N/mm2 and yield strength of reinforcing steel up to 600 N/mm2 respectively. The companion volume provides detailed worked examples on use of these high strength materials. This book is written primarily for structural engineers and designers who are familiar with basic EC4 design, and should also be useful to civil engineering undergraduate and graduate students who are studying composite steel concrete design and construction. Equations for design resistances are presented clearly so that they can be easily programmed into design spreadsheets for ease of use.
