DESCRIPTION:Dr. Benny Raphael\nAutomated construction sites involve many c
 omplexities related to micro-level details and it is impossible to anticip
 ate all the conditions that might arise. Unless the structure is carefully
  monitored\, accidents may happen. In this research\, we use structural re
 sponses to monitor the state of construction. Using the principles of syst
 em identification\, we attempt to infer normal and abnormal conditions tha
 t might arise during construction. A hybrid algorithm\, combining model ba
 sed methods and machine learning\, is used for identifying the state of th
 e system. The input data to the machine learning module consists of a time
  series of acceleration and strain components. The goal is to output the c
 lass labels denoting different structural states. Initial experiments have
  been conducted using an automated construction system in which nine accel
 erometers and eight strain gauges were used to measure structural response
 s at regular time intervals. Training data are sensor readings during cont
 rolled experiments as well as simulations. This is used to develop a suppo
 rt vector classification model which is used in prediction. Results from t
 he experiments will be presented in the seminar. Application of the method
 ology to a railway bridge in Chennai will also be presented.\n\nDr. Benny 
 Raphael is a Professor in the Department of Civil Engineering at IIT Madra
 s. He did his BTECH and M.S. in Civil Engineering at IIT Madras and obtain
 ed his PhD in Civil Engineering from the University of Strathclyde\, Glasg
 ow. He worked at Infosys Technologies Ltd. Bangalore\, EPFL Switzerland an
 d NUS Singapore\, before joining IIT Madras. He co-authored the books Fund
 amentals of Computer Aided Engineering (John Wiley\, 2003) and Engineering
  Informatics (John Wiley\, 2013) which are used as textbooks in many Unive
 rsities. He won the distinguished R&D award from the Minister for National
  Development (Government of Singapore) in 2011 for innovations in developi
 ng the Zero Energy Building at the BCA Academy\, Singapore. He has publish
 ed about 60 papers in peer reviewed international journals and has won the
  best paper award of the American Society of Civil Engineers (ASCE) Journa
 l of Computing in Civil Engineering in the years 2008 and 2013. His resear
 ch interests are in the areas of optimization\, computer aided engineering
 \, BIM\, automation and control\, and energy efficient buildings.\n
