Title: Distributed fiber optic sensing for infrastructure engineering
Design, construction, maintenance and upgrading of civil engineering infrastructure requires fresh thinking to minimize use of materials, energy and labor. This can only be achieved by understanding the actual performance of the infrastructure, both during its construction and throughout its design life. Recent advances in distributed sensing technologies such as fiber optic based sensing can radically change the quality and quantity of information we can get from civil engineering infrastructure. In this talk, several case studies using distributed fiber-optics sensors to understand the performance of tunnels, piles and underground construction in London, UK are presented. The value of the dense spatial and temporal data obtained from these sensor systems will be discussed.
Kenichi Soga is the Donald H. McLaughlin Professor of Mineral Engineering and a Chancellor’s Professor at the University of California, Berkeley. He obtained his BEng and MEng from Kyoto University in Japan and PhD from the University of California at Berkeley.He was Professor of Civil Engineering at the University of Cambridge before joining UC Berkeley in 2016. He has published more than 400 journal and conference papers in the area of infrastructure sensing, performance based design and maintenance of underground structures and energy geotechnics. He is a founding member of the Cambridge Centre for Smart Infrastructure and Construction (CSIC) based at Cambridge University. CSIC is an international center of excellence in sensors, data analysis and interpretation, and smart city systems,. He and his team have been developing sensing systems and data analysis tools to provide a platform for delivering data that enables smarter and proactive asset management decision-making, both during construction of new infrastructure and for existing structures. He is the editor-in-chief of the Institution of Civil Engineer’s Smart Infrastructure and Construction Journal and the chair of American Society of Civil Engineer Infrastructure Resilience Division’s Emerging Technologies Committee. He is a Fellow of the UK Royal Academy of Engineering and a Fellow of the Institution of Civil Engineers. He is the recipient of awards including George Stephenson Medal and Telford Gold Medal from the Institution of Civil Engineers and Walter L. Huber Civil Engineering Research Prize from the American Society of Civil Engineers.
Title: The Impact of Lidar on Archaeological Research at the Ancient Maya City of Caracol, Belize
Abstract: Perceptions about the ancient Maya have changed significantly in the last decade with the advent of new technologies and as a result of continuous dedicated research that seeks to define their social and political organization. With its ability to penetrate dense tropical canopies, LiDAR has revolutionized the field of Mesoamerican settlement archaeology. Because dense vegetation covers most ancient remains in the Maya area, archaeological documentation of the spatial extent of sites using traditional means was both difficult and usually incomplete. LiDAR was initially applied to the site of Caracol, Belize in April 2009 and yielded a 200 sq km Digital Elevation Model that, for the first time, provided a complete view of how the archaeological remains from a single Maya site – its monumental architecture, roads, residential settlement, and agricultural terraces – were distributed over the landscape. In May 2013, an additional 1057 sq km of LiDAR data were recorded in west-central Belize. For the site of Caracol, these LiDAR data may be combined with 35 years of continuous archaeological research and excavation to formulate temporal parameters and guide social and political interpretations. The conjoined information derived from LiDAR and archaeological research is significantly changing our perceptions of ancient Maya civilization by demonstrating the anthropogenic changes made to landscapes, the scale of Maya urban settlements, and the socially complex situations that existed within and between Maya polities.
Biography: Diane Z. Chase is the Vice President for Academic Innovation, Student Success, and Strategic Initiatives at Claremont Graduate University. She previously was a Pegasus Professor in Anthropology at the University of Central Florida and more recently served as the Executive Vice President and Provost at the University of Nevada, Las Vegas. She holds undergraduate and graduate degrees in Anthropology from the University of Pennsylvania. She has authored more than 150 articles and book chapters as well as several books, including the co-edited Mesoamerican Elites: An Archaeological Assessment (Univ. of Oklahoma Press, 1992). She is currently completing a co-authored book entitled Maya Archaeology: Reconstructing an Ancient Civilization (Univ. of Oklahoma Press). She further serves co-editor for the Maya Studies series at the University Press of Florida, which has published 21 volumes. She has actively been involved in archaeological field work for much of her life and is Co-Director of the Caracol Archaeological Project in Belize (with Arlen F. Chase), which has carried out 36 consecutive excavation seasons at this massive ancient Maya city. Part of her research agenda at Caracol included pioneering the use of LiDAR in Maya archaeology. Her archaeological activities resulted in her being elected as a Fellow in the American Association for the Advancement of Science.
