Both modern mathematical music theory and computer science are strongly influenced by the theory of categories and functors. One outcome of this research is the data format of denotators, which is based on set-valued presheaves over the category of modules and diaffine homomorphisms. The functorial approach of denotators deals with generalized points in the form of arrows and allows the construction of a universal concept architecture. This architecture is ideal for handling all aspects of music, especially for the analysis and composition of highly abstract musical works. This book presents an introduction to the theory of module categories and the theory of denotators, as well as the design of a software system, called Rubato Composer, which is an implementation of the category-theoretic concept framework. The application is written in portable Java and relies on plug-in components, so-called rubettes, which may be combined in data flow networks for the generation and manipulation of denotators. The Rubato Composer system is open to arbitrary extension and is freely available under the GPL license. It allows the developer to build specialized rubettes for tasks that are of interest to composers, who in turn combine them to create music. It equally serves music theorists, who use them to extract information from and manipulate musical structures. They may even develop new theories by experimenting with the many parameters that are at their disposal thanks to the increased flexibility of the functorial concept architecture. Two contributed chapters by Guerino Mazzola and Florian Thalmann illustrate the application of the theory as well as the software in the development of compositional tools and the creation of a musical work with the help of the Rubato framework.
Examining the layers of meaning encoded in software and the rhetoric surrounding it, this book offers a much-needed perspective on the intersections between software, morality, and politics. In software development culture, evangelism typically denotes a rhetorical practice that aims to convert software developers, as well as non-technical lay users, from one platform to another (e.g., from the operating system Microsoft Windows to Linux). This book argues that software evangelism, like its religious counterpart, must also be understood as constructing moral and political values that extend well beyond the boundaries of the development culture. Unlike previous studies that locate such values in the effects of code in-use or in certain types of code like free and open source (FOSS) software, Maher argues that all code is meaningful beyond its technical, executable functions. To facilitate this analysis, this study builds a theory of evangelism and illustrates this theory at work in the proprietary software industry and FOSS communities. As an example of political liberalism at work at the level of code, these evangelical rhetorics of software construct competing conceptions of what is good that fall within a shared belief in what is just. Maher illustrates how these beliefs in goodness and justice do not always execute in replicable ways, as the different ways of decoding software evangelisms in the contexts of Brazil and China reveal. Demonstrating how software evangelisms exert a transformative force on the world, one comparable in significance to code itself, this book highlights the importance of rhetoric in even the most seemingly a-rhetorical of technical endeavors and foregrounds the crucial need for rhetorical literacy in the digital age.
This book is the productof my research at the EndowedChair of Corporate Finance and Capital Markets at the European Business School. Many people devoted their inspiration, time, and knowledge in order to support me with my interdisciplinary research. Thank you all for your support. Especially, I thank my academic supervisor Prof. Ulrich Hommel, Ph.D., who provided me with the freedom to pursue my research interests and who always s- ported me generously. In addition, I am very grateful to my co-supervisor Prof. Dr. Susanne Strahringer (TU Dresden), who graciously accepted the task of refer- ing my book. Also, I thank Prof. Dr. Matthias Krause of the Chair for Theoretical Computer Science in Mannheim for the technical and computer scienti?c support. During my research visits I received generous support from Prof. Yaneer Bar- Yam (NECSI and Harvard) and Prof. John D. Sterman (MIT), who introduced me to the ?eld of System Dynamics and Complex Systems, as well as from Prof. Victor Mossotti (U.S. Geological Survey), Prof. Hiroki Sayama (NECSI and Bingh- ton), Prof. Markus de Aguiar (Universidade Estadual de Campinas), Prof. Michel Baranger (MIT), Prof. Jay W. Forrester (MIT), and Prof. Brian D. Josephson (Cambridge). Thank you very much for numerous inspiring discussions.
Using C, this book develops the concepts and theory of data structures and algorithm analysis in a gradual, step-by-step manner, proceeding from concrete examples to abstract principles. Standish covers a wide range of both traditional and contemporary software engineering topics. The text also includes an introduction to object-oriented programming using C++. By introducing recurring themes such as levels of abstraction, recursion, efficiency, representation and trade-offs, the author unifies the material throughout. Mathematical foundations can be incorporated at a variety of depths, allowing the appropriate amount of math for each user.
