Search and test algorithms for Triple Product Property triples
In 2003 COHN and UMANS introduced a group-theoretic approach to fast matrix
multiplication. This involves finding large subsets of a group satisfying
the Triple Product Property (TPP) as a means to bound the exponent of
matrix multiplication. We present two new characterizations of the TPP, which
are useful for theoretical considerations and for TPP test algorithms. With
this we describe all known TPP tests and implement them in GAP algorithms. We
also compare their runtime. Furthermore we show that the search for subgroup
TPP triples of nontrivial size in a nonabelian group can be restricted to the
set of all nonnormal subgroups of that group. Finally we describe brute-force
search algorithms for maximal subgroup and subset TPP triples. In addition we
present the results of the subset brute-force search for all groups of order
less than 25 and selected results of the subgroup brute-force search for
2-groups, and .Comment: 14 pages, 2 figures, 4 tables; ISSN (Online) 1869-6104, ISSN (Print)

Modeling and Control of a UPFC System Using Pole-Placement and Hinf Robust Control Techniques
This is an open access article distributed under Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International license (CC BY-NC-ND 4.0) https://creativecommons.org/licenses/by-nc-nd/4.0/FACTS (Flexible AC Transmission Systems) technology has now been accepted as a potential solution to the stability problem and load flow. The Unified Power Flow Controller (UPFC) is considered to be the most powerful and versatile among all FACTS devices. This paper presents the modeling and control of a UPFC system using pole-placement and H robust control techniques. A simulation study using Matlab/Simulink is presented to compare the performance of these control strategies and their robustness with respect to variations is the system parameters such as the inductance of the transmission line.Peer reviewe
