Residual closeness for helm and sunflower graphs
(Işık University Press, 2017-06-06)Vulnerability is an important concept in network analysis related with the ability of the network to avoid intentional attacks or disruption when a failure is produced in some of its components. Often enough, the network ... -
Matrix transform of irregular weyl-heisenberg wave packet frames for L² (R)
(Işık University Press, 2017)Cordoba and Fefferman [4] introduced wave packet systems by applying certain collections of dilations, modulations and translations to the Gaussian function in the study of some classes of singular integral operators. In ... -
