<strong>2005</strong> <strong>Graduate</strong> <strong>Catalog</strong> <strong>and</strong> <strong>2004</strong> <strong>Annual</strong> R & D <strong>Report</strong><br />
<strong>Sirindhorn</strong> International Institute of Technology (SIIT)<br />
been studied by conducting experiments on a<br />
polymeric model that has a similar but less complex<br />
structure. The latter is investigated by employing a<br />
novel polymer blend methodology. .<br />
Conventional <strong>and</strong> Two-Dimensional FTIR<br />
Spectroscopy<br />
Infrared spectroscopy is a fundamental analytical<br />
technique that is widely used in material characterization.<br />
Recently, an advanced methodology, twodimensional<br />
infrared spectroscopy (2D-IR) has been<br />
developed as a novel data analysis <strong>and</strong> presentation<br />
technique. This technique has provided notable<br />
advantages over conventional FTIR. For example, an<br />
improvement in b<strong>and</strong> resolution, simplicity in b<strong>and</strong><br />
assignment, <strong>and</strong> determination of relative order of<br />
responses of specific functional groups to external<br />
perturbation, have been achieved. The 2D-IR has<br />
been applied to study effects of mechanical <strong>and</strong><br />
electrical perturbations on the structural transition of<br />
PVDF/TrFE/CTFE piezoelectric polymer, <strong>and</strong><br />
investigate crystallization of biodegradable polymer,<br />
poly(lactides).<br />

Research Interests:<br />
Complex-Survey Designs <strong>and</strong> Estimation<br />
A complex-survey design incorporates elements such<br />
as stratification, clustering, unequal inclusion<br />
probabilities, <strong>and</strong> weighting, among others. Under a<br />
complex design, observations do not follow the<br />
st<strong>and</strong>ard assumptions of Independent Identically<br />
Distributed (IID) observations of classic statistical<br />
analysis. Missing values induce bias, <strong>and</strong> imputation<br />
contributes to inflate variances. The way these<br />
different factors interact is not well known. Survey<br />
designs must integrate all the components of the<br />
population structure. Estimation <strong>and</strong> variance<br />
estimation must account for all the complexities of the<br />
design.<br />
Disclosure Avoidance<br />
Government agencies are required to protect<br />
respondents’ confidentiality, both to comply with law<br />
requisites as well as to insure an accurate data<br />
collection. The public release of microdata prompts<br />
the risk of identification of a respondent by a third<br />
party. Masking techniques, such as data disturbance<br />
or swapping, to avoid the linking of observations to<br />
respondents, are typical methods to prevent identity<br />
disclosure. Masking procedures, however, distort the<br />
data <strong>and</strong> induce bias. The challenge is to produce<br />
public data files that are representative of the<br />
population <strong>and</strong>, at the same time, insure the<br />
respondents’ privacy.<br />
Entire Functions of Order Larger than One<br />
The theory of nonharmonic Fourier series is<br />
concerned with the completeness <strong>and</strong> expansion<br />
properties of sets of complex exponentials. Its origins<br />
lie in the celebrated works of Paley <strong>and</strong> Wiener <strong>and</strong> of<br />
Levinson. In recent years, in response to the growing<br />
interest in Banach spaces, research in this area has<br />
flourished. An entire function of order r is an analytic<br />
function in the complex plane satisfying |f(z)| <<br />
exp(|z| r+e ) for all e > 0 but for no e < 0, <strong>and</strong> for<br />
sufficiently large values of |z|. The growth of such<br />
functions is restricted by their growth along the real<br />
axis.<br />

Areas of Specialization: Theoretical <strong>and</strong> computational plasma physics.<br />
Research Interest:<br />
Theoretical <strong>and</strong> Computational Plasma Physics<br />
Fusion-related research with focus on thermal <strong>and</strong><br />
particle transport such as predicting the time evolution<br />
of temperature <strong>and</strong> density profiles in tokamaks using<br />
an integrated modeling approach. Integrated<br />
modeling is an important element of tokamak fusion<br />
research that contributes in an essential way to the<br />
interpretation <strong>and</strong> planning of experiments, validation<br />
of theory against experimental results, development<br />
of plasma control techniques, <strong>and</strong> the design of next<br />
step devices such as ITER. Research is closely<br />
related to ongoing <strong>and</strong> proposed experiments at<br />
major fusion laboratories.<br />
