Kris Stewart restarted grad school at SDSU in 1977, trying to find a field that used the math she likes so much. She enrolled in grad Statistics, did not like. Numerical Analysis, Math 693a/b taught by Dr. Jim Ross using Ortega's "Numerical Analysis: A Second Course", she liked this ALOT! Built her IMSAI Z-80 microcomputer kit, and received Masters in CS in 1979. 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 in Pasadena and he wanted to return to San Diego. The Pasadena time did let Glen discover his professional passion, Greene and Greene fine woodworking, scroll down to p22 in the linked article to 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.

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 chair and Dr. David Lesley and Dr. Arnold L Villone comprising the rest of her Masters project committee. The document was published by John C. Dvorak, California Software, El Cerrito Ca, 1979. Abstract: SCRUNCH is a suite of 9 numerical analysis routines coded in BASIC for microcooputers providing solutions to many typical computations. Part 1 of this paper discusses general aspects of numerical computations on memory-limited computers with specific data for the routines in SCRUNCH. Part 2 provides support for each individual routine. A separately available appendix (in the the form of listings or 5" diskette) contains the source code of the numerical routines along with test drivers for each."
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 Operating System and BASIC with 32K of 250 ns memory, from North_Star_Computers. This system was also equipped with a North Star Floating Point Board (FPB-A) and a Canada Systems Real Time Clock for accuracy and timing comparisons." Kris built her IMSAI 8080 microcomputer from a kit purchased in 1977. IMSAI_8080.

1984 FT Krogh / K Stewart Asymptotic Absolute Stability for BDFs Applied to Stiff Differential Equations ACM Trans Math Softw, 10 #1, March 1984, pg 45-57
Abstract: Methods based on backward differentiation formulas (BDFs) for solving stiff differential equations require iterating to approximate the solution of the corrector equation on each step. One hope for reducing the cvost of this is to make with iteration matrices that are known to have errors and to do no more iterations than are necessary to maintain the stability of the method. This paper, following work by Klopfenstem, examines the effect of errors in the iteration matrix on the stability of the method. Appication of the results to an algorithm is discussed briefly. This work became starting point for PhD research at UNM

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.

1990 Undergraduate Curriculum Development in Advanced Computing, NSF Award #9015552, Dan Sulzbach (Principal Investigator), Awardee Sponsored Research Office: General Atomics, San Diego CA 92121-1122.
Abs: This project supports the development and application of a general interdisciplinary undergraduate course in advanced computing that can be adopted at many colleges and universities. The principal investigator, Dr. Dan Sulzbach, is a staff member at the San Diego State University. The course will be developed by Dr. Sulzbach and Dr. Kris Stewart, a faculty member at San Diego State University and first utilized at San Diego State University which is a member of the twenty campus California State University system (CSU). After testing at SDSU, the course will be distributed to the other CSU campuses via a one-week workshop during Summer 1991 at SDSC. In 1992 a workshop for faculty from U.S. colleges and universities and a symposium at SIAM will be held to foster the distribution of the course in other institutions.

1992 T Geveci, K Stewart, Numerical Experiments with Non-Linear Evolution Equation that Exhibits Blow-up", Applied Numerical Mathematics 10 (1992) 139-147;
Abstract: The results of numerical experiments which involve a nonlinear evolution equation exhibiting blow-up and the use of spectral and pseudospectral methods are examined. It is observed that in spite of the expected exponential-order accuracy of these methods in the case of smooth solutions, they do not perform well in the detection of blow-up. paper

2000 Kris Stewart, Ilya Zaslavsky, High-Performance Computing Technologies, and Pre-Service Teacher Preparation: Is There an Overlap? (Post-Evaluation Thoughts) Society for Information Technology & Teacher Education International Conference, 2000
Abstract: In this paper, we share our experience in the development of successful programs focused on promoting high performance computational tools in undergraduate science education, and among high school teachers. The two NSF-supported projects we will describe, are the Education Center on Computational Science and Engineering, established on the campus of SDSU two years ago, and STEP, the Supercomputer Teacher Enhancement Program. Both projects have been evaluated, using a variety of questionnaire surveys and interviews. This gave us the material to assess what worked and what didn't, and share the lessons we learned. Pre-service teachers fall in the gap between the target audiences of these two projects. We believe that some of the tried and proven techniques used in our two projects are applicable to pre-service teacher education, and argue for the need of a project focused on integrating high-performance computing technologies in teacher preparation. A replicable project of this nature would address the widening gap between the rapidly changing computing environment and needs of the marketplace, on the one hand, and the awareness of teachers and their students of such changes, on the other hand. paper
