The first comprehensive overview of Peter Weibel’s visionary work, covering over half a century of artistic expression from material to machines to media.Peter Weibel: Art as an Act of Cognition presents the first comprehensive overview of the work of Peter Weibel (1944–2023), an influential artist who anticipated key developments in the art of the late twentieth and twenty-first centuries and evolved new utopian visions of a free society and individual freedom. As one of the first artists to create VR installations, Weibel was also a leading figure in the expansion of the arts into other modes of reality. His work revealed the perceptual mechanisms by which reality is constructed not only socially, but also neurologically. This publication, insightfully edited by Jens Lutz and Philipp Ziegler, covers over half a century of his artistic expression, and traces his groundbreaking migration from material to machines to media.This book follows the trajectory of Weibel’s work with various media—from literature to photography, from performance art to video to expanded cinema, from sculpture, sound art, and light art to digital artworks. It presents more than 400 distinctive creations by Weibel. Insightful essays and texts are accompanied by over 1200 illustrations, many never seen before. Analyses by acclaimed scholars contextualize and situate Weibel’s works within art historical and philosophical discourses, elaborate on his pioneering contributions, and establish his immense influence. The book draws on the artist’s large personal archive, presenting early draft concepts as well as personal historical statements, many of which are published here in English for the first time. Additionally, 35 videos can be accessed via QR code—featuring original works and commentaries by the artist himself.

This book is based on an institutional evolutionary theoretical view to the Göta kanal. Canals were the major transport infrastructure system besides roads and maritime transport until railroads were introduced. The canal studied is the Swedish Göta kanal project during the preparation and construction phase from 1800¿1832. Thus, the Göta kanal, and the canal-era, is seen from a technological, an economic and a political perspective. Comparisons are made with two contemporary major canal-projects; the Erie Canal in the USA (1817¿1825) and the Caledonian Canal in Britain (1804¿1822). It is argued that the Göta kanal project, as Sweden's Mega Project of its time, represented an important development step in Sweden as regards learning and innovation and became a starting point for Swedish transport infrastructure projects in the time to come, primarily the railways.

This monograph represents the outcome of research effort of the authors on scalable synchronization of large-scale multi-agent systems (MAS). Cooperative control of multi-agent systems has been growing in popularity and is highly interdisciplinary in recent years. The application of synchronization of MAS includes automobile systems, aerospace systems, multiple-satellite GPS, high-resolution satellite imagery, aircraft formations, highway traffic platooning, industrial process control with multiple processes, and more. Most of the proposed protocols in the literature for synchronization of MAS require some knowledge of the communication network such as bounds on the spectrum of the associated Laplacian matrix and the number of agents. These protocols suffer from scale fragility wherein stability properties are lost for large-scale networks or when the communication graph changes. In the past few years, the authors of this monograph have worked on developing scale-free protocol design for various cases of MAS problems. The key contribution of the monograph is to offer a scale-free design framework and provide scale-free protocols to achieve synchronization, delayed synchronization, and almost synchronization in the presence of input and communication delays, input saturation and external disturbances. The scale-free design framework solely is based on the knowledge of agent models and does not depend on information about the communication network such as the spectrum of the associated Laplacian matrix or size of the network. Drawing upon their extensive work in this area, the authors provide a thorough treatment of agents with higher-order dynamics, different classes of models for agents, and the underlying networks representing actions of the agents. The high technical level of their presentation and their rigorous mathematical approach make this monograph a timely and valuable resource that will fill a gap in the existing literature.

There has been an increased interest in renewable energy sources in the last few decades. Modern power systems rely mainly on power electronic-based generation and loads, leading to the adoption of smart grids that leverage digital communication infrastructure. Smart grids have several advantages, including the potential to provide consumers with a continuous power supply, reduced line losses, enhanced renewable output and storage, consumer participation in electricity markets, and demand-side responsiveness. Future power systems, also known as smart grids, will rely more on renewable energy sources, such as solar and wind, as well as storage. Power electronic converters are used in renewable energy generation and storage. Each converter/inverter manufacturer has an algorithm for programming and optimizing hardware. Furthermore, these converters rely on communication protocols to respond to any signal from the system operator. As a result, cyber-attacks on these smart converters/inverters are a concern. Although numerous cyber-physical systems (CPS) have been presented, no universal CPS standard can be employed with various types of converters. This reprint is a collection of specialized work addressing cybersecurity challenges.
