RESEARCH EXPERIENCE

Summer 2016:

Currently participating in undergraduate research through the Vibes and Waves in Action Program at the Center for Advanced Computation Telecommunications (CACT), UMASS Lowell.

 

Research Topic : Ultrasonic Imaging of Biological Tissue

 

Week of May 30, 2016:  The goal this week was to begin learning to program using Fortran 90. The first project was to create a two-dimensional complex array that represents a wave function in space and time. The programs are to be implemented on Linux servers, so the activity also included learning basic Linux commands and the use of Emacs editor.  The program was to generate slices of the wave function in space and time and display the graphs. The second part of the project was to use the data generated to identify the frequency and the wavenumber given the speed of sound. The second project was to convert a rectangular pulse in the time domain into the frequency domain using the Fourier Transform.

 

Week of June 6, 2016:  The goal this week was to gain a general understanding of beam steering and its applications using one dimensional arrays. The first part of the project was to generate a beam in the x-z plane. The second part of the project was, given the array is fixed on the x-axis, to calculate the directivity of the generated beam and display the directivity graphically.

 

Week of June 13, 2016:  The goal this week was to continue the beamsteering project of the previous week. The first objective was to vary the number of elements in the array of transducer elements and determine the differences in the directivity graphs. The next part of the project was to vary the angle of rotation from the x-axis for the array and display the directivity graphically.

 

Week of June 20, 2016: The goal this week was to gain a general understanding of signal and system relationships, as well as to explore noise. The project was to generate noise data and to analyze the data using the probability distribution.

 

Week of June 27, 2016:  The goal of the week was to gain an understanding of the physics behind harmonic ultrasound imaging, including acoustic impedance and ultrasonic attenuation. A secondary goal of the week was to learn about time sampling and the process of converting the data to the frequency domain.

 

Week of July 4, 2016:  The goal this week was to learn how to apply a Fast Fourier Transform, FFT, program to a periodic signal. Inorder to complete this objective, the noise project of Week June 20, 2016 was extended. The extension was to use a FFT program was to create a power spectral density, psd, function of the noise function generated. A secondary goal of the week was to gain a general understanding of the difference between linear and non-linear systems.

 

Week of July 11, 2016:  The goal this week was to understand the process of deriving the acoustic wave equation. This included the discovery of the relationships between the conservation of mass equation, the conservation of momentum equation, and the equation of state. An additional goal of the week was to learn the mean of calculating the wave equation through the separation of variables method.

 

Week of July 18, 2016:  The goal of the week was to understand the Finite Difference Time Domain, FDTD, method. The project of the week was to compute a one-dimensional wave equation using finite difference approximations. A secondary project of the week was to apply the knowledge of the one-dimensional wave equation to a vibrating string problem.

 

Week of July 25, 2016:
