Description:

Developed a coarse-grained, planar model of a cell moving across a grid of collagen fibers representing the ECM, in the above fig. The ECM fibers are modeled as segmented chains with each segment composed of a spring and damper element. This model is based on the formation of focal adhesions between the cell and individual fibers, a discrete model. The cell randomly extends filopodia and forms focal adhesions when it encounters one. After one forms, the cells' trailing edge releases its focal adhesions and the cell contracts, creating overall movement. This simplified model was intended to capture the elasticity of the cell membrane interacting with an elastic ECM. It was of interest to determine what role the stiffness of the substrate had on cell locomotion. Preliminary examination of this system suggests that a multiscale analysis would yield a scaling that would speed up the simulation run time significantly; however, we are still verifying this. The goal of the proposed work is to replace the spring-damper elements representing processes within the cell, with the smaller scale physical phenomena. This will yield a more accurate model of cellular locomotion and allow discovery of new physical phenomena and insights into the mechanisms behind cellular locomotion.

Rover CAD model

RASC-AL Robo-Ops Competition by NASA

Robotics, Biomechanics, and Dynamic Systems Laboratory
The University of Texas at Arlington
January 2012 - February 2013
Adviser: Prof. Alan Bowling

Keywords:

Description:

Worked in a team to design and fabricate a rover prototype to remotely perform tasks on NASA's rock yard. Volunteered to lead the sub assembly team, responsible for design and fabrication of the drive train. Characterized the right spring stiffness for suspension based on the simulation of the rover. Designed the fixtures to hold the motors and the suspension arms to the chassis of the rover using Pro-E 5.0.

Structural Analysis of Wind Loading on Tower Cranes

JNTU Kakinada
August 2010 - May 2011
Adviser: Prof. Ravi Kumar Naradasu

Keywords:

Description:

Collaborated with industry on this team project which was aimed at studying the effect of wind gusts on tower cranes. Generated an optimized mesh for CFD model of the tower crane using the CFDExpert and developed the finite element model of the tower crane in ANSYS 11.0. It was noted that when the crane is loaded to its maximum load of 2850 kg (at max. radius), the deflection without wind loading was 18.45 cms (7.2 in), within the permissible limits (Eden et.al, 2001). However, when subjected to the wind loads of 72 KMPH (45 MPH), with the crane fully loaded, the lateral torque on the jib was calculated to be 63.17 NM, which affects the slewing unit that connects the jib to the mast, while the permitted torque on slewing unit was 60 NM (Eden et.al, 2001).
