Some Past Research Topics
My recent work is centered on computational
algorithms
and
computer
technology
in
the design of geometric sculpture,. I am also very
interested in puzzle design and
the history of geometry in
art. Some areas of my past research that people still
contact me about are briefly summarized below, with pointers to
further information.
1. Multidimensional Analysis
The study of ``dimensioned quantities," such as 1 volt, and
2 meters, and their possible interrelationships, forms an
interesting branch of applied mathematics (or physics or
engineering) called dimensional analysis. Traditionally this
field only concerns scalar quantities (not vectors and matrices).
The linear algebra which results when one considers vectors and
matrices which contain dimensioned quantities as their components
is surprisingly interesting and rich. Although it is implicit in
all branches of modern engineering, it has not been carefully
studied before.
For an introduction to dimensioned linear algebra and the
dimensional analysis of matrix relationships, be sure to check out
my Multidimensional
Analysis page, and check out my book, which
assumes an undergraduate background in linear algebra:
George W. Hart, Multidimensional Analysis: Algebras and
Systems for Science and Engineering, Springer Verlag, 1995.
Software for Scalars:
A very useful computer program (which I have written and placed
in the public domain) for manipulating, converting, and
calculating with dimensioned scalars is available, DimCalc,
runs under Windows 3.1 or higher software. The file to get is DimCalc.zip which is a compressed
package of the software and extensive on-line help information.
Expand the directory someplace and double click the dimcalc.exe file within it to
run the program.
2. Nonintrusive Appliance Load Monitoring
A Nonintrusive Appliance Load Monitor determines the energy
consumption of individual appliances turning on and off in an
electric load, based on detailed analysis of the current and
voltage of the total load, as measured at the interface to the
power source. The approach has been developed to simplify the
collection of residential energy consumption data by utilities,
but also has other applications. It is called nonintrusive
to contrast it with previous techniques for gathering appliance
load data, which require placing sensors on individual appliances,
and hence an intrusion onto the energy consumer's property.
An interesting aspect of this research is the interdisciplinary
manner in which it combines power systems theory and
communications theory---power consumption is decoded as an act of
information transfer. The theory and current practice of
Nonintrusive Appliance Load Monitoring, including goals,
applications, load models, appliance signatures, algorithms,
prototypes, field-test results, current research directions, and
the advantages and disadvantages of this approach relative to
intrusive monitoring are described in the following tutorial
survey article:
G. Hart, ``Nonintrusive Appliance Load Monitoring," IEEE
Proceedings, December 1992, pp. 1870-1891.

Monitoring Page.
