Expert Talk on Array Signal Processing for Acoustic and Brain Source Localization-Dr. Lalan Kumar

We are pleased to announce an insightful expert talk by Dr. Lalan Kumar, Assistant Professor in the Department of Electrical Engineering at IIT Delhi. Dr. Kumar will share his expertise on "Array Signal Processing for Acoustic and Brain Source Localization" on 8th August 2024, starting at 09:00 AM. With an impressive background that includes a Post-Doc from NTU, Singapore, experience as a Software Engineer at Motorola, and a former faculty position at IIT Bhubaneswar, Dr. Kumar brings a wealth of knowledge and practical insights to the table. This session promises to be a valuable opportunity for students, faculty, and professionals interested in signal processing and its applications in acoustic and brain source localization.

The Brinell hardness number (BHN) is the load divided by the surface area of indentation. The diameter of the impression is measured with a microscope with a superimposed scale. BHN remains vital parameters for the assessment of weld quality and also to eliminate post weld crack formation. The focus of this study is to predict tig process parameter such as Brinell hardness number (BHN)  for  eliminating  post  weld  crack  formation,  and  stabilizing  heat  input  in  mild  steel  weldment.  The  key  input  parameters  considered  in  this  work  are  welding  current,  welding  voltage  and  welding  speed  while  the  response  or  measured  parameter  is  Brinell  hardness  number  (BHN).  Using  the  range  and  levels  of  the  independent  variables,  statistical  design  of  experiment  (DOE)  using central composite design (CCD) method was done. Hundred (100) pieces of mild steel coupons measuring 60 x 40 x10 were used  for  the  experiments.  The  experiment  was  performed  20  times,  using  5  specimens  for  each  run.  The  plate  samples  were  60  mm long with a wall thickness of 10mm. The samples were cut longitudinally with a Single-V joint preparation. The tungsten inert gas welding equipment was used to weld the plates after the edges have been bevelled and machined. The welding process uses a  shielding  gas  to  protect  the  weld  specimen  from  atmospheric  interaction.  For  this  study,  100%  pure  Argon  gas  was  used.  The  weld samples were made from 10mm thickness of mild steel plate; the plate was cut to size with the power hacksaw. The edges grinded and surfaces polished with emery paper and the joints welded and thereafter, the response (Brinell hardness number) was measured, recorded, and analysed using fuzzy logic.
