Pygmalion’s Power: Romanesque Sculpture, the Senses, and Religious Experience
by Thomas E. DalePushed to the height of its illusionistic powers during the first centuries of the Roman Empire, sculpture was largely abandoned with the ascendancy of Christianity, as the apparent animation of the material image and practices associated with sculpture were considered both superstitious and idolatrous. In Pygmalion’s Power, Thomas E. A. Dale argues that the reintroduction of architectural sculpture after a hiatus of some seven hundred years arose with the particular goal of engaging the senses in a Christian religious experience. Since the term “Romanesque” was coined in the nineteenth century, the reintroduction of stone sculpture around the mid-eleventh century has been explained as a revivalist phenomenon, one predicated on the desire to claim the authority of ancient Rome. In this study, Dale proposes an alternative theory. Covering a broad range of sculpture types—including autonomous cult statuary in wood and metal, funerary sculpture, architectural sculpture, and portraiture—Dale shows how the revitalized art form was part of a broader shift in emphasis toward spiritual embodiment and affective piety during the late eleventh and twelfth centuries.Adding fresh insight to scholarship on the Romanesque, Pygmalion’s Power borrows from trends in cultural anthropology to demonstrate the power and potential of these sculptures to produce emotional effects that made them an important sensory part of the religious culture of the era.

Pyrotechnic Cities: Architecture, Fire-Safety and Standardisation (Routledge Research in Architecture)
by Liam RossThis book explores the relationship between architecture, government and fire. It posits that, through the question of fire-safety standardisation, building design comes to be both a problem for, and a tool of, government. Through a close study of fire-safety standards it demonstrates the shaping effect that architecture and the city have on the way we think about governing. Opening with an investigation into the Grenfell Tower fire and the political actors who sought to enrol it in programmes of governmental reform before contextualising the research in current literature, the book takes four city studies, each beginning with a specific historic fire: The 1654 Great Fire of Meirecki, Edo; the 1877 town fire of Lagos; the 1911 Empire Palace Theatre fire, Edinburgh; and the 2001 World Trade Centre attack, New York. Each study identifies the governmental response to the fire, safety standards and codes designed in its wake and how these new processes spread and change. Drawing on the work of sociologists John Law and Anne Marie Mol and their concept of ‘Fire Space’, it describes the way that architectural design, through the medium of fire, is an instrument of political agency. Pyrotechnic Cities is a critical investigation into these political implications, written for academics, researchers and students in architectural history and theory, infrastructure studies and governance.

Qayrawān: The Amuletic City (Refiguring Modernism)
by William GalloisIn the last years of the nineteenth century, the Tunisian city of Qayrawān suddenly found itself covered in murals. Concentrated on and around the city’s Great Mosque, these monumental artworks were only visible for about fifty years, from the 1880s through the 1930s. This book investigates the fascinating history of who created these outdoor paintings and why.Using visual archaeological methods, William Gallois reconstructs the visual history of these works and vividly brings them back to life. He locates pictorial records of the murals from the backdrops of photographs, postcards, and other forms of European ephemera. In Qayrawān, he identifies a form of religious painting that transposed traditional aesthetic forms such as house decoration, embroidery, and tattooing—which lay exclusively within the domains of women—onto the body of a conquered city. Gallois argues that these works were created by women as a form of “emergency art,” intended to offer amuletic protection for the community, and demonstrates how they differ markedly from “classical” Islamic antecedents and modern modes of Arab cultural production in the Middle East and North Africa.Based on extensive archival research, this study is both a record of a unique moment in the history of art and a challenge to rethink the spiritual force and agency of a group of anonymous female artists whose paintings aspired to help save the world at a time of great peril. It will be welcomed by scholars of art history, Islamic studies, Middle East studies, and the history of magic.
Qorbanot: Offerings (SUNY series in Contemporary Jewish Literature and Culture)
by Alisha KaplanA dynamic dialogue of poetry and art that reimagines the ancient, biblical concept of sacrifice.Winner of the 2022 Gerald Lampert Memorial Award presented by the League of Canadian Poets A collaboration between poet Alisha Kaplan and artist Tobi Aaron Kahn, Qorbanot-the Hebrew word for "sacrificial offerings"-explores the concept of sacrifice, offering a new vision of an ancient practice. A dynamic dialogue of text and image, the book is a poetic and visual exegesis on Leviticus, a visceral and psychological exploration of ritual offerings, and a conversation about how notions of sacrifice continue to resonate in the twenty-first century.Both from Holocaust survivor families, Kaplan and Kahn deal extensively with the Holocaust in their work. Here, the modes of poetry and art express the complexity of belief, the reverberations of trauma, and the significance of ritual. In the poems, the speaker, offspring of burnt offerings, searches for meaning in her grandparents' experiences and in the long tradition of Orthodox Judaism in which she was raised. Kahn's paintings on handmade paper, drawn from decades of his career as an artist, have not previously been exhibited or published. They reflect his quest to distill a legacy of trauma and loss into enduring memory.With a foreword by James E. Young and essays by Ezra Cappell, Lori Hope Lefkovitz, and Sasha Pimentel, the book presents new directions for thinking about what sacrifice means in religious, social, and personal contexts, and harkens back to foundational traditions, challenging them in reimagined and artistic ways.

Quabbin Valley: Life As It Was (Images of America)
by Elizabeth PeirceQuaben, the Nipmuc Indian word for "many waters," was the name originally given to the area of central Massachusetts that is now known as the Quabbin Valley. The abundance of ponds, lakes, and streams in the region made it an obvious target for those seeking new water sources to supply the escalating population of Boston in the late 19th century. However, the little towns of Dana, Enfield, Greenwich, and Prescott that were established in the area stood in the way. Following an act of the legislature in 1926, these towns were disincorporated, and the 2,500 inhabitants were given modest compensation and ordered to leave. By 1938, the former towns were flooded and stood at the floor of the reservoir, which held the potential of 420 billion gallons of water to be outsourced eastward. Never to be forgotten, the story of the lost towns and their former residents are displayed through artifacts housed at the Swift River Valley Historical Society in North New Salem.
Quad City International Airport (Images of Aviation)
by David T. CoopmanIn 1922, three men were so captivated with flying they leased 30 acres of cow pasture south of Moline to serve as a landing field. Other early aviators and barnstormers began using Franing Field, and it soon became known as Moline Airport. The field hosted the Ford Reliability Tour four times, served as part of the original New York to Dallas airmail route, had passenger service as early as 1927, became one of Illinois's largest Works Progress Administration projects, weathered financial struggles and a battle with neighboring Davenport, Iowa, over which community would possess the area's commercial airport, and has enjoyed constant growth and updates for both airline and general aviation traffic. This collection of historical photographs and images will present the people, planes, events, and development of that former pastureland into today's modern Quad City International Airport, the third largest airport for passenger traffic in the state of Illinois.
Quad Rotorcraft Control
by Rogelio Lozano Claude Pégard Luis Rodolfo García Carrillo Alejandro Enrique Dzul LópezQuad Rotorcraft Control develops original control methods for the navigation and hovering flight of an autonomous mini-quad-rotor robotic helicopter. These methods use an imaging system and a combination of inertial and altitude sensors to localize and guide the movement of the unmanned aerial vehicle relative to its immediate environment. The history, classification and applications of UAVs are introduced, followed by a description of modelling techniques for quad-rotors and the experimental platform itself. A control strategy for the improvement of attitude stabilization in quad-rotors is then proposed and tested in real-time experiments. The strategy, based on the use low-cost components and with experimentally-established robustness, avoids drift in the UAV's angular position by the addition of an internal control loop to each electronic speed controller ensuring that, during hovering flight, all four motors turn at almost the same speed. The quad-rotor's Euler angles being very close to the origin, other sensors like GPS or image-sensing equipment can be incorporated to perform autonomous positioning or trajectory-tracking tasks. Two vision-based strategies, each designed to deal with a specific kind of mission, are introduced and separately tested. The first stabilizes the quad-rotor over a landing pad on the ground; it extracts the 3-dimensional position using homography estimation and derives translational velocity by optical flow calculation. The second combines colour-extraction and line-detection algorithms to control the quad-rotor's 3-dimensional position and achieves forward velocity regulation during a road-following task. In order to estimate the translational-dynamical characteristics of the quad-rotor (relative position and translational velocity) as they evolve within a building or other unstructured, GPS-deprived environment, imaging, inertial and altitude sensors are combined in a state observer. The text give the reader a current view of the problems encountered in UAV control, specifically those relating to quad-rotor flying machines and it will interest researchers and graduate students working in that field. The vision-based control strategies presented help the reader to a better understanding of how an imaging system can be used to obtain the information required for performance of the hovering and navigation tasks ubiquitous in rotored UAV operation.
