For my detailed professional activities, please refer to
my
CV.
Summer presentations of 1996:
Teaching: Creating interactive teaching and
learning material with Maple, MathView, Scientific
WorkPlace (or Scientific Notebook), Java and etc. I am
visiting Singapore for one year,
click
here for the project(s) that I am doing in
Singapore. (June 97-May 98)
Research: Used
Uniform Regular Matrices in partition an interval,
(click here for
example) and develop open and closed types of
adaptive quadratures in one and two dimensions. The
quadratures can be used in estimating (non absolute)
integrals such as f(x)=(1/x)*sin(1/x) or f(x,y)=(1/xy)*sin(1/xy)
directly without using transformation technique. Note
that the functions mentioned above are Henstock
integrable but not Lebesgue integrable. (What Needs to
be done is the error analysis. If you are interested, I
would very much like to hear from you.
- Integrals that Maple and Mathematica can't handle or give wrong answers.
- Example 1 Maple and Mathematica can't handle this function since the singular points are located along x = y.
- Example 2 Both Maple and Mathematica give answers 0, which are wrong. Since the double integral integral does not exist even if the repeated integrals is 0. This example shows that the existence of a double integral is essential for one to estimate its value since the existence and equality of the repeated integrals of a function (such as in this case) need not imply that the double integral of the function exists.
