by Carla C. Johnson Janet B. Walton Erin E. Peters-BurtonWhat if you could challenge your eighth graders to design a racing vehicle with minimum environmental impact, while exploring the role of renewable and non-renewable energy sources? With this volume in the STEM Road Map Curriculum Series, you can! The Speed of Green outlines a journey that will steer your students toward authentic problem solving while grounding them in integrated STEM disciplines. Like the other volumes in the series, this book is designed to meet the growing need to infuse real-world learning into K–12 classrooms. This interdisciplinary, eight-lesson module uses project- and problem-based learning to help students explore the potential role of renewable and non-renewable energy sources in transportation, with an emphasis on the auto industry. Using their understanding of the engineering design process (EDP), scientific concepts, and environmental conservation considerations, student teams will develop a plan for a competitive automobile racing team to fuel its vehicle with minimal environmental impact. To support this goal, students will do the following: · Identify finite energy resources and distinguish between these and renewable energy sources, and identify implications of the use of those fuel sources on the environment; · Conduct life cycle analyses (LCAs) of various fuel sources and apply the results to make decisions about the effects of various fuel sources; · Identify several ways that carbon-based fuels have impacted the U.S. economy and foreign relations; · Identify the effects of human activities on the biosphere with an emphasis on the effects of the widespread use of carbon-based fuels; · Apply the engineering design process (EDP) to solve a problem, and design and build a small-scale electric vehicle; · Synthesize their learning and working collaboratively by creating and presenting a plan for a race team that minimizes its environmental impact; · Create an engaging presentation incorporating oral presentations and visual displays to present projects to an audience of peers, teachers, and industry professionals. The STEM Road Map Curriculum Series is anchored in the Next Generation Science Standards, the Common Core State Standards, and the Framework for 21st Century Learning. In-depth and flexible, The Speed of Green can be used as a whole unit or in part to meet the needs of districts, schools, and teachers who are charting a course toward an integrated STEM approach.

Speeding-Up Radio-Frequency Integrated Circuit Sizing with Neural Networks (SpringerBriefs in Applied Sciences and Technology)
by João L. Domingues Pedro J. Vaz António P. Gusmão Nuno C. Horta Nuno C. Lourenço Ricardo M. MartinsIn this book, innovative research using artificial neural networks (ANNs) is conducted to automate the sizing task of RF IC design, which is used in two different steps of the automatic design process. The advances in telecommunications, such as the 5th generation broadband or 5G for short, open doors to advances in areas such as health care, education, resource management, transportation, agriculture and many other areas. Consequently, there is high pressure in today’s market for significant communication rates, extensive bandwidths and ultralow-power consumption. This is where radiofrequency (RF) integrated circuits (ICs) come in hand, playing a crucial role. This demand stresses out the problem which resides in the remarkable difficulty of RF IC design in deep nanometric integration technologies due to their high complexity and stringent performances. Given the economic pressure for high quality yet cheap electronics and challenging time-to-market constraints, there is an urgent need for electronic design automation (EDA) tools to increase the RF designers’ productivity and improve the quality of resulting ICs. In the last years, the automatic sizing of RF IC blocks in deep nanometer technologies has moved toward process, voltage and temperature (PVT)-inclusive optimizations to ensure their robustness. Each sizing solution is exhaustively simulated in a set of PVT corners, thus pushing modern workstations’ capabilities to their limits. Standard ANNs applications usually exploit the model’s capability of describing a complex, harder to describe, relation between input and target data. For that purpose, ANNs are a mechanism to bypass the process of describing the complex underlying relations between data by feeding it a significant number of previously acquired input/output data pairs that the model attempts to copy. Here, and firstly, the ANNs disrupt from the most recent trials of replacing the simulator in the simulation-based sizing with a machine/deep learning model, by proposing two different ANNs, the first classifies the convergence of the circuit for nominal and PVT corners, and the second predicts the oscillating frequencies for each case. The convergence classifier (CCANN) and frequency guess predictor (FGPANN) are seamlessly integrated into the simulation-based sizing loop, accelerating the overall optimization process. Secondly, a PVT regressor that inputs the circuit’s sizing and the nominal performances to estimate the PVT corner performances via multiple parallel artificial neural networks is proposed. Two control phases prevent the optimization process from being misled by inaccurate performance estimates. As such, this book details the optimal description of the input/output data relation that should be fulfilled. The developed description is mainly reflected in two of the system’s characteristics, the shape of the input data and its incorporation in the sizing optimization loop. An optimal description of these components should be such that the model should produce output data that fulfills the desired relation for the given training data once fully trained. Additionally, the model should be capable of efficiently generalizing the acquired knowledge in newer examples, i.e., never-seen input circuit topologies.
Spektren, Garben, Schemata: Eine kurze Einführung (essentials)
by Jürgen JostDas essential führt in die wesentlichen Konzepte der modernen algebraischen Geometrie ein. Dabei werden zunächst algebraische Grundbegriffe wiederholt. Die algebraische Struktur eines kommutativen Ringes spiegelt sich in der Menge seiner Primideale wider. Diese Menge kann mit einer topologischen Struktur versehen werden; dies ist der Begriff des Spektrums, der also algebraische in topologische Daten übersetzt. Mithilfe des Begriffs der Garbe kann man aus dieser topologischen die algebraische Struktur zurückgewinnen. Dieses reichhaltige Wechselspiel wird im Begriff des Schemas erfasst. Dadurch kann man die grundlegenden Objekte der algebraischen Geometrie, Nullstellengebilde von Polynomen, algebraisch untersuchen und umgekehrt geometrische Methoden auf arithmetische Fragen anwenden.

Spherical Radial Basis Functions, Theory and Applications
by Simon Hubbert Quôc Thông Lê Gia Tanya M. MortonThis book is the first to be devoted to the theory and applications of spherical (radial) basis functions (SBFs), which is rapidly emerging as one of the most promising techniques for solving problems where approximations are needed on the surface of a sphere. The aim of the book is to provide enough theoretical and practical details for the reader to be able to implement the SBF methods to solve real world problems. The authors stress the close connection between the theory of SBFs and that of the more well-known family of radial basis functions (RBFs), which are well-established tools for solving approximation theory problems on more general domains. The unique solvability of the SBF interpolation method for data fitting problems is established and an in-depth investigation of its accuracy is provided. Two chapters are devoted to partial differential equations (PDEs). One deals with the practical implementation of an SBF-based solution to an elliptic PDE and another which describes an SBF approach for solving a parabolic time-dependent PDE, complete with error analysis. The theory developed is illuminated with numerical experiments throughout. Spherical Radial Basis Functions, Theory and Applications will be of interest to graduate students and researchers in mathematics and related fields such as the geophysical sciences and statistics.

Spieltheorie: Theorie und Verfahren zur Lösung von Nash- und verallgemeinerten Nash-Gleichgewichtsproblemen (Mathematik Kompakt)
by Christian Kanzow Alexandra SchwartzDas Buch gibt eine Einführung in einige zentrale Konzepte der (mathematischen) Spieltheorie und legt seinen Fokus dabei auf die Lösung von Nash- und verallgemeinerten Nash-Gleichgewichtsproblemen. Die meisten Probleme der Spieltheorie lassen sich nicht von Hand lösen; stattdessen ist man auf geeignete numerische Verfahren angewiesen, mit deren Hilfe zumindest eine Näherungslösung berechnet werden kann. Einen Schwerpunkt dieses Buches bilden daher eine ganze Reihe von Methoden meist neueren Datums, die hier erstmals in Buchform präsentiert werden und zur numerischen Lösung von Nash- und verallgemeinerten Nash-Gleichgewichtsproblemen verwendet werden können. Aber auch Existenz- und Eindeutigkeitssätze sowie Zwei-Personen-Spiele werden ausführlich diskutiert. Darüber hinaus werden in eigenen Abschnitten die benötigten mathematischen Grundlagen zur Verfügung gestellt. Dazu gehören Aussagen über konvexe und monotone Funktionen sowie Optimalitätsbedingungen aus der restringierten Optimierung.

Spinning Strings and Correlation Functions in the AdS/CFT Correspondence (Springer Theses)
by Juan Miguel NietoThis book addresses several aspects of the integrable structure of the AdS/CFT correspondence. In particular it presents computations made on both sides of the AdS/CFT correspondence, at weak and at strong coupling. On the string theory side of the correspondence, the book focuses on the evaluation of the energy spectrum of closed string solutions moving in some deformed backgrounds that preserve integrability. On the gauge theory side, it explores various formal problems arising in the computation of two and three-point functions by means of the Algebraic Bethe Ansatz and the Quantum Inverse Scattering method. The book features numerous results on integrability in the context of the AdS/CFT correspondence. Self-contained and pedagogical, it includes general discussions and detailed presentations on the use of integrable systems techniques and their applications.

Spline and Spline Wavelet Methods with Applications to Signal and Image Processing
by Valery A. Zheludev Pekka Neittaanmäki Amir Z. AverbuchThis book presents various contributions of splines to signal and image processing from a unified perspective that is based on the Zak transform (ZT). It expands the methodology from periodic splines, which were presented in the first volume, to non-periodic splines. Together, these books provide a universal toolbox accompanied by MATLAB software for manipulating polynomial and discrete splines, spline-based wavelets, wavelet packets and wavelet frames for signal/ image processing applications. In this volume, we see that the ZT provides an integral representation of discrete and polynomial splines, which, to some extent, is similar to Fourier integral. The authors explore elements of spline theory and design, and consider different types of polynomial and discrete splines. They describe applications of spline-based wavelets to data compression. These splines are useful for real-time signal processing and, in particular, real-time wavelet and frame transforms. Further topics addressed in this volume include: "global" splines, such as interpolating, self-dual and smoothing, whose supports are infinite; the compactly supported quasi-interpolating and smoothing splines including quasi-interpolating splines on non-uniform grids; and cubic Hermite splines as a source for the design of multiwavelets and multiwavelet frames. Readers from various disciplines including engineering, computer science and mathematical information technology will find the descriptions of algorithms, applications and software in this book especially useful.
