The Switch
From the telegraph to the touchscreen, how the
development of binary switching transformed everyday life and
changed the shape of human agency
The Switch traces the sudden rise of a technology that
has transformed everyday life for billions of people: the binary
switch. By chronicling the rapid growth of binary switching since
the mid-nineteenth century, Jason Puskar contends that there is no
human activity as common today as pushing a button or flipping a
switch-the deceptively simple act of turning something on or off.
More than a technical history, The Switch offers a
cultural and political analysis of how reducing so much human
action to binary alternatives has profoundly reshaped modern
society.
Analyzing this history, Puskar charts the rapid shift from
analog to digital across a range of devices-keyboards, cameras,
guns, light switches, computers, game controls, even the \"nuclear
button\"-to understand how nineteenth-century techniques continue to
influence today's pervasive digital technologies. In contexts that
include musical performance, finger counting, machine writing,
voting methods, and immersive play, Puskar shows how the switch to
switching led to radically new forms of action and thought.
The innovative analysis in The Switch makes clear that
binary inputs have altered human agency by making choice
instantaneous, effort minimal, and effects more far-reaching than
ever. In the process, it concludes, switching also fosters forms of
individualism that, though empowering for many, also preserve a
legacy of inequality and even domination.

Robust optimization of spline models and complex regulatory networks : theory, methods and applications
This book introduces methods of robust optimization in multivariate adaptive regression splines (MARS) and Conic MARS in order to handle uncertainty and non-linearity. The proposed techniques are implemented and explained in two-model regulatory systems that can be found in the financial sector and in the contexts of banking, environmental protection, system biology and medicine. The book provides necessary background information on multi-model regulatory networks, optimization and regression. It presents the theory of and approaches to robust (conic) multivariate adaptive regression splines - R(C)MARS - and robust (conic) generalized partial linear models - R(C)GPLM - under polyhedral uncertainty. Further, it introduces spline regression models for multi-model regulatory networks and interprets (C)MARS results based on different datasets for the implementation. It explains robust optimization in these models in terms of both the theory and methodology. In this context it studies R(C)MARS results with different uncertainty scenarios for a numerical example. Lastly, the book demonstrates the implementation of the method in a number of applications from the financial, energy, and environmental sectors, and provides an outlook on future research.

Performance Modeling and Design of Computer Systems
Tackling the questions that systems designers care about, this book brings queueing theory decisively back to computer science. The book is written with computer scientists and engineers in mind and is full of examples from computer systems, as well as manufacturing and operations research. Fun and readable, the book is highly approachable, even for undergraduates, while still being thoroughly rigorous and also covering a much wider span of topics than many queueing books. Readers benefit from a lively mix of motivation and intuition, with illustrations, examples and more than 300 exercises – all while acquiring the skills needed to model, analyze and design large-scale systems with good performance and low cost. The exercises are an important feature, teaching research-level counterintuitive lessons in the design of computer systems. The goal is to train readers not only to customize existing analyses but also to invent their own.

Induction Motor Computer Models in Three-Phase Stator Reference Frames
This book is a compilation of knowledge about computer models in the three-phase stator reference frame. Chapters explore several aspects of the topic and build upon research previously presented by contributors. The book aims to provide interesting solutions to problems encountered in the design of railway and analysis in railway motors. The modeling approaches proposed by the authors in this book may become an incentive for readers and researchers to develop their 'lifehacks' to solve new problems in induction motor design and testing. Key topics presented in the book: - Approximate calculations of induction motor equivalent T-shaped circuit parameters with the use of catalogue data - Simulations of different types of shaft load, including fluid coupling - Receiving static characteristics of an electric machine during simulation by means of dynamic model - Simulation of the electric drive's specific applications with three-phase induction motors building - Direct start of an induction motor as part of an auxiliary drive of an AC electric locomotive, containing a capacitor phase splitter, starting with different types of shaft loads (fan or compressor). Special attention has been given to the description of the thermal model of an induction motor with a squirrel-cage rotor, which makes it possible to simulate operating modes when powered by an unbalanced voltage, as well as with squirrel cage defects. The thermal model is presented as a detailed superstructure to the model of electromechanical processes of an induction electric machine. Other key features of the book include references for further reading, an appendix for the parameters of the equivalent thermal circuit of an NVA-55 induction motor. The material presented in the book is of interest to railway motor engineers, specialists in electromechanics and electric drives who use
SPICE-compatible CAD applications in their work.

Modellierung und Simulation als Werkzeug zur Bewertung technischer Entwicklungsoptionen am Beispiel der Großkraftwerkstechnik
Ausgehend von Anwendungsproblemen des Werkzeugs \"Modellierung und Simulation\" wird eine praxisnahe Vorgehensweise abgeleitet, die simulationsbasierte Vergleichsstudien unter den Aspekten Nachvollziehbarkeit, Vergleichbarkeit und Realitätsnähe erlaubt. Diese wird am Beispiel der Entwicklungsoptionen der Großkraftwerkstechnik hinsichtlich Wirkungsgradsteigerung und CO2-Emissionsminderung genutzt. Betrachtet werden stein- und braunkohlebefeuerte Dampfkraftwerke nach dem Stand der Technik, deren möglichen Fortentwicklung durch gesteigerte Dampfparameter, Braunkohlevortrocknung sowie CO2-Abtrennung im Post-Combustion- und Oxyfuel-Verfahren. Zudem werden die Unterschiede verschiedener Gasturbinenmodelle bei erdgasbefeuerten GuD-Kraftwerken untersucht.A methodology with a practical orientation is derived from experienced issues in the application of mod-elling and simulation. This methodology allows the simulation based comparative studies in terms of their replicability, comparability and modelling close to reality. It is used to investigate development options of utility sized power plants with regard to efficiency improvements and/or CO2 emission reductions. The study compares current state of the art hard coal fired and lignite fired steam power plants and their improvements by increasing steam parameters, lignite pre-dying as well as the application of CO2 capture by post combustion or oxyfuel technology. Furthermore, the impact of using different gas turbine models for natural gas fired combined cycle power plants are studied.
