A NOVEL MODEL FOR THE CONTAMINATION OF A SYSTEM OF THREE ARTIFICIAL LAKES
Hatipoğlu, Veysel Fuat (AMER INST MATHEMATICAL SCIENCES, 2021)In this study, a new model has been developed to monitor the contamination in connected three lakes. The model has been motivated by two biological models, i.e. cell compartment model and lake pollution model. Haar wavelet ... -
ON SOME BETA-FRACTIONAL INTEGRAL INEQUALITIES
Uçar, Deniz; Hatipoğlu, Veysel Fuat (Yildiz Technical Univ, 2019)In this paper, we obtain some new integral inequalities using beta-fractional integrals in the case of two synchronous functions. For this purpose we state and prove several theorems. Our results are pioneer for the ... -
