Quick BIO:
Kris Beard attended Vista High School 1966-69 and then proceeded to UCSD to pursue Math Degree at Muir College, graduated after Winter Quarter 1973. Started graduate school at UC Berkeley Fall 1973, which did not go well. Returned to San Diego to work as Dr. Harmon Craig's Administrative Assistant (slave) for a few years at Scripps Institution of Oceanography (SIO). Married Glen Stewart 26March1975 while still working at SIO.

Kris Stewart restarted grad school at SDSU, trying to pick a field that applied the math she likes so much, by taking courses - Statistics (NO) Numerical Analysis (YES). Received Masters in CS in 1979 and was hired by NASA's Jet Propulsion Lab (JPL) in Pasadena, administered by the California Institute of Technology (CalTech). Loved the job, but Glen found the air unbreathable then in Pasadena and wanted to return to San Diego, but he did discover his professional passion, Greene and Greene fine woodworking, scroll down to p31to see Glen in his shop set up in the Bolton House living room. Kris felt she needed the PhD in Computer Science / Applied Math and went to University of New Mexico (UNM) to work with Dr. Cleve Moler - with Dr. Larry Shampine identified as her thesis advisor, basing research on efforts begun with Dr. Fred Krogh at JPL.


Kris' professional career began as a numerical analyst

1980 Microcomputer In Numerical Analysis ACM SIGNUM 1980 http://dl.acm.org/citation.cfm?id=1057546 based on her CS Masters project at SDSU, Scrunch: Numerical Computations on Very Small Machines" with Dr. Verner Vinge as her thesis committee chair. "The routines in SCRUNCH are all coded ln BASIC and were developed and tested on a CROMEMCO Z-80 nicrocomputer in an IMSAI box using North Star Disk and BASIC with 32K of 250 ns memory. This system is also equipped with a North Star Floating Point Board (FPB-A) and a Canada Systems Real Time Clock for accuracy and ttming comparisons."

1984 Krogh / Stewart Asymptotic Absolute Stability for BDFs Applied to Stiff Differential Equations, ACM Trans Math Softw, 10 #1, March 1984, pg 45-57, became starting point for PhD research at UNM

1987 Semi-Implicit Backward Differentiation Formulas UNM Dissertation by Kris Stewart, April 1987

1990 A model for stability of the semi-implicit backward differentiation formulas. J. Comput. Appl. Math. 33, 3 (December 1990), 245-259 ACM Digital Lib
Abstract: A model is presented for stability for an extension of linear multistep methods for stiff ordinary differential equations. The method is based on a prediction followed by a fixed number of corrections obtained by a Newton scheme with inexact Jacobian matrix. The impact on stability of error in the matrix over a broad range of linear, constant coefficient equations is modeled. The model provides practical guidance for implementation of software for stiff equations.

1990 Avoiding Stability-induced inefficiencies in BDF methods, J of Computational and Applied Math 29 (1990) 357-367
Abstract: Time-dependent partial differential equations are often treated by semidiscretization and the resulting problem solved using existing ordinary differential equation software restricted to low-order formulas. For certain classes of problems, the Backward Differentiation Formulas (BDF) are often dismissed due to their poor stability behavior near the imaginary axis for orders three and above. We explain why and for what problems this happens, what the appropriate tactic should be, and why this is not the tactic taken by most automatic codes. We present an idea that avoids this inefficiency in one automatic code.

1994 Ad Hoc Approach to Undergraduate Curriculum Development in Computational Science, Dept of Energy, DOE, High Performance Computing Education Conference, 10Feb1994 Albuquerque NM, panel organized by Dr. Joan Francioni and Dr. Kris Stewart

The numerical analysis training evolved, naturally, into a focus on Computational Science through collaboration with the San Diego Supercomputer Center (SDSC). SDSC was founded in 1985 by Dr. Sid Karin allowing Kris to apply for access to the Cray XMP supercomputer for numerical analysis experiments and further collaborations including curriculum development at SDSU. Kris was given an office and summer salary as SDSC's Computational Science Curriculum Coordinator 1995-97.

1995 HPC Undergraduate Curriculum Development at SDSU using SDSC Resources; Education/Technical Paper (#704); Final revision August 15, 1995 SC95 Supercomputing '95, San Diego, Ca, provides a summary of my efforts to bring computational science curriculum develop to San Diego State University.

Scholarship Reconsidered - Priorities of the Professoriate by Ernest Boyer provided me with guidance and acknowledgement that I was not alone in my pursuit of success in the realm of higher education. Ernest L. Boyer's Scholarship Reconsidered offers a new paradigm that recognizes the full range of scholarly activity by college and university faculty and questions the existence of a reward system that pushed faculty toward research and publication and away from teaching.

As Kris' professional career at SDSU evolved, receiving tenure at SDSU, Kris was able to pursue topics proposed by SDSC that appealed to her. The first was to work with teams of high school science teachers in San Diego County to facilitate their using the evolving computing tools in their classroom. The WWW, World Wide Web, and browsers, such as NCSA's Mosaic, arrived just in time for this three year NSF funded project 1993-1997.

1997 STEP - A Case Study on Building a Bridge between HPC |Technologies and the Secondary Classroom (pdf) STEP (web) by Kris Stewart and Janet Bowers, presented at Supercomputing '97.

As validation of my network awareness, Kris participated in the CSU sponsored high performance network application to NSF in 1997, resulting in an award 01 March 1998 for "CalREN-2: The California Research and Education Network-Phase" NSF Award #9729574 as the coPI for SDSU.

"What Internet2 Means for SDSU Faculty" is the summary presented to Provost Marlin's Council of Deans 30june2004. SDSU did appear on the Internet2 map for several years. There's a blowup of the map as the last slide in the presentation made to the SDSU Deans, above.

The original web page for this research project, which ended December 2004, had to be removed from the SDSU system due to links not working. Dr. Kris Stewart obtained a tar file of the original site, since it chronicled so many useful activities for her. Slowly working to fix broken links - mostly of an as-needed basis. Please send email to stewart@sdsu.edu if you have questions or suggestions.

Cyber Bridge presentation - Sum2010 "Evolution of Computers and Internet as the background for Ethics". Summarizing my background for possible collaboration with San Diego Schools, luckily the team from Montgomery High School wanted to collaborate with me. The school is named after John J. Montgomery an aviation pioneer inventor. It was great to visit this school in the San Diego Southbay, near Montgomery-Waller Rec Center with the big Silver Wing celebrating first controlled winged flight 1883.
