Single-Molecule Biophysics: Studying Biology One Molecule at a Time
|
| Speaker: |
Diwakar Turaga
UMass-Amherst/Washington University St.Louis
Diwakar Turaga has recently graduated from University of Massachusetts, Amherst with
Bachelors of Science degrees in Biochemistry & Molecule Biology, and Physics.
His research experiences include 1) Study of single-molecule mechanics of Green
Fluorescent Protein (GFP) using AFM, under Prof. Julio Fernandez (Columbia
University), 2) Study of mobility of polyelectrolytes using conductivity and
diffusion measurements, under Prof. Murugappan Muthukumar (UMass-Amherst), and
3) Study of the effect of crowding on protein folding, under Prof. Lila
Gierasch (UMass-Amherst). He will be pursuing an MD/PhD degree at Washington
University, St. Louis, starting this August.

| Abstract: |
Single molecule studies have been in the forefront of biomedical research
during the last five years. Techniques like optical tweezers, Atomic Force
Microscopy (AFM), and single-molecule fluorescence have revolutionized our
understanding of the basic building blocks of our body, namely proteins, DNA
and RNA. I will give a general introduction to these single-molecule
techniques and provide a few examples of its impact on our understanding of a
biological system.

| Title: |
Error Resilient Video Compression Techniques
|
| Speaker: |
Dr. Sunil Kumar
Electrical and Computer Engineering Department
Clarkson University
Potsdam, New York, USA- 13699
Sunil Kumar received B.E. (Electronics Engineering) degree from S.V.
National Institute of Technology, Surat
(India), in 1988 and the M.E. (Electronics & Control Engineering) and
Ph.D. (Electrical and Electronics Engineering) degrees from the Birla
Institute of Technology and Science,
Pilani (India) in 1993 and 1997, respectively. He also served in the
Electrical and Electronics Engineering department of the Birla Institute
of Technology and Science, Pilani (India)
as a Lecturer from January 1993 to July 1997. From August 1997 to August
2002, he was a Postdoctoral Researcher and Adjunct Faculty in Signal and
Image Processing Institute, Integrated Media Systems Center and
Electrical Engineering-Systems Department at University of Southern California, Los
Angeles. From July 2000 to July 2002, he was also an Expert Consultant
in industry on JPEG2000 and MPEG4-based projects and participated in
JPEG2000 standardization activities. Since August 2002, he has been with
Electrical and Computer Engineering department at Clarkson University, Potsdam, NY. His
research interests include QoS support for Multimedia Traffic in
Wireless Cellular and Adhoc Networks, Error Resilient Multimedia (image,
video, and 3D graphics) Compression Techniques, MPEG-4, H.264/AVC and
JPEG2000 Image/Video Compression Standards, and Biomedical Image Processing.

| Abstract: |
Lately, newer mobile and wireless-based applications are emerging that
require transmission of multimedia data on wireless channels. As a
result, increasing attention is being paid to design video compression
schemes that are scalable and resilient (or robust) to error prone
wireless channels.
In this talk, the need for error resiliency will be discussed followed
by a brief description of error resiliency schemes (e.g., data
partitioning, data recovery, flexible macroblock ordering, redundant
slides) included in recent MPEG-4 and H.264/AVC video coding standards.
The Reversible Variable Length Code (RVLC) is an important error
resiliency scheme adopted in MPEG-4 standard. As a result RVLCs have
witnessed renewed interest and some new RVLC codes have been proposed by
leading researchers during the past 2-3 years. Our following recent
research on the RVLC codes will also be discussed in this talk: (i)
improved error detection and data recovery from a corrupted MPEG-4 video
bitstream, and (ii) comparative performance (compression efficiency,
error propagation and error resiliency) of various RVLCs for different
types of sources, including MPEG-4 bitstream.

| Abstract: |
Government of Andhra Pradesh is considered to be a leader in its use
of IT to offer variety of services and bring about transparency and
accountability in its internal operations.
In this presentation, after a brief introduction to the architecture,
and the landscape of e-Governance applications from Government of Andhra
Pradesh, a few applications will be presented by the developers to
illustrate the diversity of IT applications. Various issues related to the
deployment of applications in a practical setting will be talked about.
Some pointers to further applications that can be taken up by the teams
as potential projects will be mentioned.
