k-autocorrelation and its applications
(Ankara Üniversitesi Fen Fakültesi, 2019-02-01)The standard autocorrelation measures similarities between a binary sequence and its any shifted form. In this paper, we introduce the concept of the k-autocorrelation of a binary sequence as a generalization of the standard ... -
Local pre-Hausdorff extended pseudo-quasi-semi metric spaces
(Ankara Üniversitesi Fen Fakültesi, 2019-02-01)In this paper, we characterize local pre-Hausdorff extended pseudo-quasi-semi metric spaces and investigate the relationships between them. Finally, we show that local pre-Hausdorff extended pseudo-quasi-semi metric spaces ... -
Mathematical Analysis and Numerical Simulations for the Cancer Tissue Invasion Model
(Ankara Üniversitesi, 2019-02-01)Cancer cell invasion is one of the most important stages of metastasis. In this paper, the local existence and uniqueness of the cancer cell invasion model is proved using an iterative procedure. Moreover the numerical ... -
Maximum Lq-Likelihood Estimation for the parameters of Marshall-Olkin Extended Burr XII Distribution
(Ankara Üniversitesi, 2019-02-01)Marshall--Olkin extended Burr XII (MOEBXII) distribution is proposed by Al-Saiari et al. (2014) to obtain a more flexible family of distributions. Some estimation methods like maximum likelihood, Bayes and M estimations ... -
