Sommario/riassunto |

""When you say, 'Black is Beautiful,' what in fact you are saying. is: Man, you are okay as you are; begin to look upon yourself as a human being." With such statements, Stephen Biko became the voice of Black Consciousness. And with Biko's brutal death in the custody of the South African police, he became a martyr, an enduring symbol of the horrors of apartheid. Through the lens of visual culture, Biko's Ghost reveals how the man and the ideology he promoted have profoundly influenced |

liberation politics and race discourse--in South Africa and around the globe--ever since. Tracing the linked histories of Black Consciousness and its most famous proponent, Biko's Ghost explores the concepts of unity, ancestry, and action that lie at the heart of the ideology and the man. It challenges the dominant historical view of Black Consciousness as ineffectual or racially exclusive, suppressed on the one side by the apartheid regime and on the other by the African National Congress. Engaging theories of trauma and representation, and icon and ideology, Shannen L. Hill considers the martyred Biko as an embattled icon, his image portrayals assuming different shapes and political meanings in different hands. So, too, does she illuminate how Black Consciousness worked behind the scenes throughout the 1980's, a decade of heightened popular unrest and state censorship. She shows how--in streams of imagery that continue to multiply nearly forty years on--Biko's visage and the ongoing life of Black Consciousness served as instruments through which artists could combat the abuses of apartheid and unsettle the "rainbow nation" that followed.

Sommario/riassunto |
|
This book describes the application of vision-sensing technologies in welding processes, one of the key technologies in intelligent welding manufacturing. Gas tungsten arc welding (GTAW) is one of the main welding techniques and has a wide range of applications in the manufacturing industry. As such, the book also explores the application of AI technologies, such as vision sensing and machine learning, in GTAW process sensing and feature extraction and monitoring, and presents the state-of-the-art in computer vision, image processing and machine learning to detect welding defects using non-destructive methods in order to improve welding productivity. Featuring the latest research from ORNL (Oak Ridge National Laboratory) using digital image correlation technology, this book will appeal to researchers, scientists and engineers in the field of advanced manufacturing. |
