It was shown by Ostrik (Int. Math. Res. Not. 2003(27), 1507–1520 2003) and Natale (SIGMA Symmetry Integrability Geom. Methods Appl. 13, 042 2017) that a collection of twisted group algebras in pointed fusion category serve as explicit Morita equivalence class representatives indecomposable, separable such categories. We generalize this result constructing group-theoretical This is achieved prov...

This article explores the efficiency of motion-compensated three-dimensional transform coding, a compression scheme that employs a motion-compensated transform for a group of pictures. We investigate this coding scheme experimentally and theoretically. The practical coding scheme employs in temporal direction a wavelet decomposition with motion-compensated lifting steps. Further, we compare the...

One facet of group decision making that has escaped close scrutinization is the effect of individual biases and group biases on group work. In this paper we present a theoretical framework for using data mining based group memory to overcome the biases in group decision making situations. By studying the patterns extracted from the group memory data, the group members can develop a better under...

‎the frobenius complement of a given frobenius group acts on its kernel‎. ‎the scheme which is arisen from the orbitals of this action is called ferrero pair scheme‎. ‎in this paper‎, ‎we show that the fibers of a ferrero pair scheme consist of exactly one singleton fiber and every two fibers with more than one point have the same cardinality‎. ‎moreover‎, ‎it is shown that the restriction of a...
