Current scholarly activities involve writing a graduate level hypertext book on signal-to-noise enhancement, and exploring the impact that the Internet has on chemical instrumentation.
I no longer act as a research advisor for graduate students nor work with postdoctoral associates.
Book Project
The book on signal-to-noise enhancement covers the following material.
- probability theory
- hypothesis testing
- curve fitting
- Fourier transform theory
- signal and noise frequencies
- frequency dependent electronics
- creating and handling digital signals
- multiplexed detection
Putting the book in digital form allows cleaner discussions because derivations and non-critical examples can be made available through hypertext links. It also allows the inclusion of text searching, user annotation, and numeric worksheets.
The material has been tested over 20 semesters in CHM621, Advanced Analytical Chemistry, and has been well received by students.
Internet Project
Interest in Internet enhanced instrumentation includes the following topics.
- Internet-based control, operation and diagnosis of instrumentation
- wireless links to remote instrumentation
- instrumentation driven by remote programs
- remote operation of software using a Browser interface
- electronic communication among components within an instrument using the Internet Protocol
- security issues with Internet-driven instrumenation
Collaborations in these areas are welcomed. My present efforts involve exploring the extent that Java can be used to obtain the above objectives.
