R&I-Fließschema: Übergang von DIN 19227 zu DIN EN 62424 (essentials)
by Dieter Hofmann Thomas BindelThomas Bindel und Dieter Hofmann arbeiten Gemeinsamkeiten und Unterschiede der Normen DIN 19227 und DIN EN 62424 für die Erarbeitung von R&I-Fließschemata/R&I-Fließbildern heraus. DIN 19227, Teil 1 (Graphische Symbole und Kennbuchstaben für die Prozeßleittechnik) wurde zurückgezogen und durch DIN EN 62424 (Darstellung von Aufgaben der Prozessleittechnik – Fließbilder und Datenaustausch zwischen EDV-Werkzeugen zur Fließbilderstellung und CAE-Systemen) ersetzt, galt jedoch bis Juli 2012 fort. Da Fließschemata älterer Anlagen nach DIN 19227 erarbeitet wurden, stehen Anwender vor der Herausforderung, diese Norm nach wie vor verstehen zu müssen, für neu errichtete Anlagen dagegen DIN EN 62424 anzuwenden, die sich eher zögerlich durchzusetzen scheint. Die Autoren beleuchten die mit dem Übergang verbundenen Änderungen und geben so Orientierung zur Nutzung von DIN EN 62424.
R.U.R. and the Vision of Artificial Life
by Karel CapekA new translation of Karel Čapek&’s play R.U.R.—which famously coined the term &“robot&”—and a collection of essays reflecting on the play&’s legacy from scientists and scholars who work in artificial life and robotics.Karel Čapek's &“R.U.R.&” and the Vision of Artificial Life offers a new, highly faithful translation by Štěpán Šimek of Czech novelist, playwright, and critic Karel Čapek&’s play R.U.R.: Rossum&’s Universal Robots, as well as twenty essays from contemporary writers on the 1920 play. R.U.R. is perhaps best known for first coining the term &“robot&” (in Czech, robota means serfdom or arduous drudgery). The twenty essays in this new English edition, beautifully edited by Jitka Čejková, are selected from Robot 100, an edited collection in Czech with perspectives from 100 contemporary voices that was published in 2020 to celebrate the hundredth anniversary of the play.Čapek&’s robots were autonomous beings, but biological, not mechanical, made of chemically synthesized soft matter resembling living tissue, like the synthetic humans in Blade Runner, Westworld, or Ex Machina. The contributors to the collection—scientists and other scholars—explore the legacy of the play and its connections to the current state of research in artificial life, or ALife. Throughout the book, it is impossible to ignore Čapek&’s prescience, as his century-old science fiction play raises contemporary questions with respect to robotics, synthetic biology, technology, artificial life, and artificial intelligence, anticipating many of the formidable challenges we face today.ContributorsJitka Čejková, Miguel Aguilera, Iñigo R.

RCS Estimation of Linear and Planar Dipole Phased Arrays: Approximate Model
by Hema Singh Rakesh Mohan Jha R. ChandiniIn this book, the RCS of a parallel-fed linear and planar dipole array is derived using an approximate method. The signal propagation within the phased array system determines the radar cross section (RCS) of phased array. The reflection and transmission coefficients for a signal at different levels of the phased-in scattering array system depend on the impedance mismatch and the design parameters. Moreover the mutual coupling effect in between the antenna elements is an important factor. A phased array system comprises of radiating elements followed by phase shifters, couplers, and terminating load impedance. These components lead to respective impedances towards the incoming signal that travels through them before reaching receive port of the array system. In this book, the RCS is approximated in terms of array factor, neglecting the phase terms. The mutual coupling effect is taken into account. The dependence of the RCS pattern on the design parameters is analyzed. The approximate model is established as an efficient method for RCS estimation of phased arrays. This book presents a detailed formulation of approximate method to determine RCS of phased arrays, which is explained using schematics and illustrations. This book should help the reader understand the impinging signal path and its reflections/transmissions within the phased array system.

RF Analog Impairments Modeling for Communication Systems Simulation
by Lydi SmainiWith the growing complexity of personal mobile communication systems demanding higher data-rates and high levels of integration using low-cost CMOS technology, overall system performance has become more sensitive to RF analog front-end impairments. Designing integrated transceivers requires a thorough understanding of the whole transceiver chain including RF analog front-end and digital baseband. Communication system engineers have to include RF analog imperfections in their simulation benches in order to study and quantify their impact on the system performance.Here the author explores key RF analog impairments in a transceiver and demonstrates how to model their impact from a communication system design view-point. He discusses the design aspects of the front end of transceivers (both receivers and transmitters) and provides the reader with a way to optimize a complex mixed-signal platform by taking into account the characteristics of the RF/analog front-end.Key features of this book include:Practical examples illustrated by system simulation results based on WiFi and mobile WiMAX OFDM transceiversAn overview of the digital estimation and compensation of the RF analog impairments such as power amplifier distortion, quadrature imbalance, and carrier and sampling frequency offsetsAn exposition of the challenges involved in the design of both RF analog circuits and DSP communication circuits in deep submicron CMOS technologyMATLAB® codes for RF analog impairments models hosted on the companion websiteUniquely the book bridges the gap between RFIC design specification needs and communication systems simulation, offering readers RF analog impairments modeling knowledge and a comprehensive approach to unifying theory and practice in system modelling.

RF CMOS Oscillators for Modern Wireless Applications (River Publishers Series In Circuits And Systems Ser.)
by Robert Bogdan Staszewski Masoud Babaie Mina ShahmohammadiWhile mobile phones enjoy the largest production volume ever of any consumer electronics products, the demands they place on radio-frequency (RF) transceivers are particularly aggressive, especially on integration with digital processors, low area, low power consumption, while being robust against process-voltage-temperature variations. Since mobile terminals inherently operate on batteries, their power budget is severely constrained. To keep up with the ever increasing data-rate, an ever-decreasing power per bit is required to maintain the battery lifetime. The RF oscillator is the second most power-hungry block of a wireless radio (after power amplifiers). Consequently, any power reduction in an RF oscillator will greatly benefit the overall power efficiency of the cellular transceiver. Moreover, the RF oscillators' purity limits the transceiver performance. The oscillator's phase noise results in power leakage into adjacent channels in a transmit mode and reciprocal mixing in a receive mode. On the other hand, the multi-standard and multi-band transceivers that are now trending demand wide tuning range oscillators. However, broadening the oscillator’s tuning range is usually at the expense of die area (cost) or phase noise.The main goal of this book is to bring forth the exciting and innovative RF oscillator structures that demonstrate better phase noise performance, lower cost, and higher power efficiency than currently achievable. Technical topics discussed in RF CMOS Oscillators for Modern Wireless Applications include: Design and analysis of low phase-noise class-F oscillators Analyze a technique to reduce 1/f noise up-conversion in the oscillators Design and analysis of low power/low voltage oscillators Wide tuning range oscillators Reliability study of RF oscillators in nanoscale CMOS
