Graduate Projects

The following are a few projects that I've worked on in my graduate courses.

  1. "ECG Compression: Fast Block-Sorting Compression", Fall 2008.
    Project wherein efficient lossless compression for electrocardiographic(ECG) data is investigated with the end-goal of hardware design. Paper detailing ECG signals and block-sorting compression available here.
    Abstract:
    While electrocardiography is one of the most effective tools used by cardiologists, largely due to its noninvasive nature and the scope of diagnosis possible given a patient's ECG signals, one of its greatest drawbacks is the large data size of ECG signals. Compounded with the requirement that ECG signals only be compressed losslessly (or lossy with a very low tolerance of loss), efficient lossless compression schemes are vital for storage of patient ECG records. Further, a hardware implementation is beneficial for mobile ECG applications, such as Holter monitors and wireless ECG monitoring devices. In this project, we describe a block-sorting lossless compression scheme which achieves lower compression ratios than both Lempel-Ziv and Transform(ie Wavelet) based ECG compression methods. Further, a concise hardware design of the block-sorting scheme is sought, followed by rigorous testing.

  2. "Classification: Naive Bayes vs Logistic Regression", Fall 2009.
    Machine learning project wherein an important paper by Ng and Jordan is considered and further elaborated upon. Learning curves for Naive Bayes and Logistic Regression classifiers are produced for several data sets, and the applicability of both classifiers is discussed. Paper available here.


Undergraduate Projects
  1. "Automated waste flap door for use in Boeing aircraft lavatories", Spring 2008.
    Boeing sponsored project wherein our team designed a system to actuate the waste flap located in aircraft lavatories, meeting all safety criteria as well as current lavatory space constraints for feasiblity. Video displaying working prototype below (windows media player plugin required).

    which may help differentiate components in the above picture.

  2. "Integer solutions to the equation a^n + b^n = c^n, for n >= 2", Spring 2007.
    Paper available here.
  3. Undergraduate Research in Image Set Compression, Winter 2006 - Spring 2008.
    Explored different image compression techniques to achieve competitive compression ratios with JPEG2000.
