Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

Download or read book Toward an Architecture of Enjoyment written by Henri Lefebvre and published by U of Minnesota Press. This book was released on 2014-05-01 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Toward an Architecture of Enjoyment is the first publication in any language of the only book devoted to architecture by Henri Lefebvre. Written in 1973 but only recently discovered in a private archive, this work extends Lefebvre’s influential theory of urban space to the question of architecture. Taking the practices and perspective of habitation as his starting place, Lefebvre redefines architecture as a mode of imagination rather than a specialized process or a collection of monuments. He calls for an architecture of jouissance—of pleasure or enjoyment—centered on the body and its rhythms and based on the possibilities of the senses. Examining architectural examples from the Renaissance to the postwar period, Lefebvre investigates the bodily pleasures of moving in and around buildings and monuments, urban spaces, and gardens and landscapes. He argues that areas dedicated to enjoyment, sensuality, and desire are important sites for a society passing beyond industrial modernization. Lefebvre’s theories on space and urbanization fundamentally reshaped the way we understand cities. Toward an Architecture of Enjoyment promises a similar impact on how we think about, and live within, architecture.

Download or read book Four Decades of Scientific Explanation written by Wesley C. Salmon and published by University of Pittsburgh Press. This book was released on 2006-06-15 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: As Aristotle stated, scientific explanation is based on deductive argument-yet, Wesley C. Salmon points out, not all deductive arguments are qualified explanations. The validity of the explanation must itself be examined. Four Decades of Scientific Explanation provides a comprehensive account of the developments in scientific explanation that transpired in the last four decades of the twentieth century. It continues to stand as the most comprehensive treatment of the writings on the subject during these years.Building on the historic 1948 essay by Carl G. Hempel and Paul Oppenheim, "Studies in the Logic of Explanation," which introduced the deductive-nomological (D-N) model on which most work on scientific explanation was based for the following four decades, Salmon goes beyond this model's inherent basis of describing empirical knowledge to tells us "not only what, but also why." Salmon examines the predominant models in chronological order and describes their development, refinement, and criticism or rejection.Four Decades of Scientific Explanation underscores the need for a consensus of approach and ongoing evaluations of methodology in scientific explanation, with the goal of providing a better understanding of natural phenomena.

Download or read book Microsound written by Curtis Roads and published by National Geographic Books. This book was released on 2004-08-20 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Below the level of the musical note lies the realm of microsound, of sound particles lasting less than one-tenth of a second. Recent technological advances allow us to probe and manipulate these pinpoints of sound, dissolving the traditional building blocks of music—notes and their intervals—into a more fluid and supple medium. The sensations of point, pulse (series of points), line (tone), and surface (texture) emerge as particle density increases. Sounds coalesce, evaporate, and mutate into other sounds. Composers have used theories of microsound in computer music since the 1950s. Distinguished practitioners include Karlheinz Stockhausen and Iannis Xenakis. Today, with the increased interest in computer and electronic music, many young composers and software synthesis developers are exploring its advantages. Covering all aspects of composition with sound particles, Microsound offers composition theory, historical accounts, technical overviews, acoustical experiments, descriptions of musical works, and aesthetic reflections.

Download or read book Sound to Sense Sense to Sound written by Pietro Polotti and published by Logos Verlag Berlin GmbH. This book was released on 2008 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the 1950s, Sound and Music Computing (SMC) research has had a profound impact on the development of culture and technology in our post-industrial society. SMC research approaches the whole sound and music communication chain from a multidisciplinary point of view. By combining scientific, technological and artistic methodologies it aims at understanding, modeling, representing and producing sound and music using computational approaches. This book, by describing the state of the art in SMC research, gives hints of future developments, whose general purpose will be to bridge the semantic gap, the hiatus that currently separates sound from sense and sense from sound.
