• Sommario/riassunto: Surrogate models expedite the search for promising designs by standing in for expensive design evaluations or simulations. They provide a global model of some metric of a design (such as weight, aerodynamic drag, cost, etc.), which can then be optimized efficiently. Engineering Design via Surrogate Modelling is a self-contained guide to surrogate models and their use in engineering design. The fundamentals of building, selecting, validating, searching and refining a surrogate are presented in a manner accessible to novices in the field. Figures are used liberally to explain the key

• Sommario/riassunto: There are a number of recent texts that draw on psychoanalytic theory as an interpretative approach for understanding architecture, or that use the formal and social logics of architecture for understanding the psyche. But there remains work to be done in bringing what largely amounts to a series of independent voices, into a discourse that is greater than the sum of its parts, in the way that, say, the architect Peter Eisenman was able to do with the architecture of deconstruction or that the historian Manfredo Tafuri was able to do with the Marxist critique of architecture. The discourse of the present volume focuses specifically for the first time on the subject of the unconscious in relation to the design, perception, and understanding of architecture. It brings together an international group of contributors, who provide informed and varied points of view on the role of the unconscious in architectural design and theory and, in doing so, expand architectural theory to unexplored areas, enriching architecture in relation to the humanities. The book explores how architecture engages dreams, ; desires, imagination, memory, and emotions, how architecture can appeal to a broader scope of human experience and identity. Beginning by examining the historical development of the engagement of the unconscious in architectural discourse, and the current and historical, theoretical and practical, intersections of architecture and psychoanalysis, the volume also analyses the city and the urban condition.
