Art produced outside hegemonic centers is often seen as a form of derivation or relegated to a provisional status. Forming Abstraction turns this narrative on its head. In the first book-length study of postwar Brazilian art and culture, Adele Nelson highlights the importance of exhibitionary and pedagogical institutions in the development of abstract art in Brazil. By focusing on the formation of the São Paulo Biennial in 1951; the early activities of artists Geraldo de Barros, Lygia Clark, Waldemar Cordeiro, Hélio Oiticica, Lygia Pape, and Ivan Serpa; and the ideas of critics like Mário Pedrosa, Nelson illuminates the complex, strategic processes of citation and adaption of both local and international forms. The book ultimately demonstrates that Brazilian art institutions and abstract artistic groups—and their exhibitions of abstract art in particular—served as crucial loci for the articulation of societal identities in a newly democratic nation at the onset of the Cold War.

Abstraction is a fundamental mechanism underlying both human and artificial perception, representation of knowledge, reasoning and learning. This mechanism plays a crucial role in many disciplines, notably Computer Programming, Natural and Artificial Vision, Complex Systems, Artificial Intelligence and Machine Learning, Art, and Cognitive Sciences. This book first provides the reader with an overview of the notions of abstraction proposed in various disciplines by comparing both commonalities and differences. After discussing the characterizing properties of abstraction, a formal model, the KRA model, is presented to capture them. This model makes the notion of abstraction easily applicable by means of the introduction of a set of abstraction operators and abstraction patterns, reusable across different domains and applications. It is the impact of abstraction in Artificial Intelligence, Complex Systems and Machine Learning which creates the core of the book. A general framework, based on the KRA model, is presented, and its pragmatic power is illustrated with three case studies: Model-based diagnosis, Cartographic Generalization, and learning Hierarchical Hidden Markov Models.

Radical political shifts that raged throughout Cuba in the 1950s coincided with the development of Cuban geometric abstraction and, notably, the formation of Los Diez Pintores Concretos (Ten Concrete Painters). The decade was marked by widespread turmoil and corruption following the 1952 military coup and by rising nationalist sentiments. At the same time, Havana was undergoing rapid urbanization and quickly becoming an international city. Against this vibrant backdrop, artists sought a new visual language in which art, specifically abstract art, could function as political and social practice. Concrete Cuba marks one of the first major presentations outside of Cuba to focus exclusively on the origins of concretism in the country. It includes important works from the late 1940s through the early 1960s by the twelve artists who were at different times associated with the short-lived group: Pedro Álvarez, Wifredo Arcay, Mario Carreño, Salvador Corratgé, Sandú Darié, Luis Martínez Pedro, Alberto Menocal, José M. Mijares, Pedro de Oraá, José Ángel Rosabal, Loló Soldevilla, and Rafael Soriano. Many of the group’s members had traveled widely in the preceding years and corresponded with those at the forefront of European and South American abstract movements. Produced on the occasion of the major exhibition at David Zwirner, Concrete Cuba is the first in-depth catalogue on the subject to be published in English; the show offered a “wonderful taste of a very complicated history,” according to Roberta Smith of The New York Times. With an extensive plate section, which includes works from the exhibition and a selection of important pieces from the permanent collection of Museo Nacional de Bellas Artes, Havana, this volume provides readers with a rich visual experience of this crucial period in modernism’s history. The catalogue also features an extensively researched illustrated chronology, compiled by Susanna Temkin, which tracks the development of the period artistically and politically from 1939 through 1964. New scholarship by Abigail McEwen offers an interpretative framework for this group of artists, and a deeper understanding of the forces behind the development of this movement. Also included is a conversation between Lucas Zwirner and Pedro de Oraá, one of the central members of Los Diez.

This book surveys methods, problems, and tools used in process control engineering. The book is intended both for interested nonspecialists who wish to become acquainted with the discipline of process control engineering and for process control engineers.
