Prof. Violet Syrotiuk @ SBA Research for intensive research discussions and exchange
Professor Violet Syrotiuk from Arizona State University visited the MATRIS Research Group for two days of intensive research discussions and exchange from October 24-25, 2024. Prof. Syrotiuk is a distinguished researcher in mathematical system dynamics modeling, wireless networks, and algorithm development.
During her visit, Prof. Syrotiuk gave a talk on “Combinatorial Requirements for Large Scale Screening Experiments“, joint work with Charles J. Colbourn, John Stufken, and Yasmeen Akhtar, where she discussed the use of combinatorial designs for testing and screening of wireless networks. Screening experiments, which are traditionally used to identify key factors that significantly impact system responses.
Prof. Syrotiuk highlighted the assumptions and limitations often embedded in conventional screening designs, such as limiting the number of factors, using only two levels for each factor, and neglecting interactions between factors. Additionally, she discussed the constraints of assuming balanced designs, continuous system reporting, predictable response directions, and normally distributed data. She presented recent combinatorial advancements to address these limitations, including results from a large-scale screening experiment conducted on a wireless network testbed. She also noted how these methodologies have broader applications, particularly in software testing.
After the break, the members of the MATRIS Research Group contributed actively to the scientific exchange by presenting related research activities, such as an application of combinatorial designs for testing complex systems, the generation of covering perfect hash-families for creating covering arrays, and computational results on the numbers of (non-) equivalent covering arrays of a fixed size.
The vibrant discussions and mutual exchange of ideas during this visit lay the groundwork for fruitful future collaborations between the MATRIS Research Group and Prof. Violet Syrotiuk, with the aim of advancing innovations in adaptive and non-adaptive testing and screening of complex systems.
