PROJECTS

M.S. Thesis: Normalization of Complex Mode Shapes by Truncation of the α–polynomial, Aug 2014 – present

Proposed a pre-processing technique for normalization of mode shapes and elimination of damping from the modal frequencies of the system

Tested this concept using software X-Modal and MATLAB on data obtained from shaker test of a circular plate

Devised an explanation for the deviation in the undamped natural frequencies obtained using this model with the help of 2, 3 and 4 degree of freedom (DOF) analytical systems

Developed an alternate post-processing normalization technique using partial fraction method of residue synthesis and successfully tested it on data obtained from impact testing of a rectangular plate

Data Acquisition and Modal Analysis of a Circular and Rectangular Plate, April 2014

Acquired data using a VXI system for both circular and rectangular plate

The circular plate was excited with three shakers and the rectangular plate with an impact hammer

Using X-Modal, different excitation techniques and algorithms were used to process the data and the resulting modal frequencies, modes shapes and Modal Assurance Criteria (MAC) were compared

Multiple Input Multiple Output (MIMO) Data Processing, Nov 2013

Using MATLAB, processed the vibration data obtained from a circular plate utilizing windows, aliasing and averaging techniques and analysis functions such as the power spectrum and coherence

Multi-Functional Robot; Final year (Bachelor of Engineering) project, July 2012 – June 2013

Designed and assembled a working model of a remotely operated multi-function robot which could move across different terrains, transmit real time images of the environment around and could carry a 1 kg payload

EXPERIENCE

Teaching Assistant, Department of Mechanical and Materials Engineering, University of Cincinnati; May 2014 – Present

Conduct the Structures Motion Control Laboratory, a senior year laboratory, with the help of another teaching assistant (TA) (Aug 2015 – Dec 5, 2015)

Graded quizzes and homework for a junior year course, System Dynamics and Vibrations (Jan 2015 – Aug 2015)

Conducted laboratory for courses Circuits & Sensing (May 2014 – Dec 2014; May 2015 – Aug 2015), a sophomore year course, and Mechatronics & Instrumentation (Jan 2015 – May 2015), a junior year course, with the help of two other TAs and assisted the students with their problems related to the experiments, laboratory reports and MATLAB codes
