Aggregating user preferences in group recommender systems: A crowdsourcing approach
(Elsevier, 2022)We present that group recommendations are similar to crowdsourcing, where the responses of different crowd workers are aggregated in the absence of ground truth. With this in mind, we mimic the use of the EM algorithm as ... -
An entropy empowered hybridized aggregation technique for group recommender systems
(Elsevier, 15.03.2021)Group recommender systems aim to suggest appropriate products/services to a group of users rather than individuals. These recommendations rely solely on determining group preferences, which is accomplished by an aggregation ... -
Cytotoxic effect, spectroscopy, DFT, enzyme inhibition, and moleculer docking studies of some novel mesitylaminopropanols: Antidiabetic and anticholinergics and anticancer potentials
(Elsevier, 09.10.2021)b-Amino alcohols (2–4) used in this study were re-synthesized in accordance with our previous study. All compounds were characterized by the combination of NMR, UV–Vis, IR experimental and theoretical spectral data. Then, ... -
Davulalan A-type granitoid-associated Cu, Mo, Pb, Zn, and REEs mineralization, Central Anatolia, Turkey
(Elsevier, Aralık 202)In recent years, due to the high-reserve metallic and/or non-metallic mines detected in A-type granitoids, this interest is growing in these granitoids. Davulalan syenitoid is one of the A-type granitoids which are intruded ... -
Development of new adsorbents via microwave treatment magnetic PET synthesis from waste PET and investigation of TC removal
(Elsevier, 2021)In this study; new, economic and environment friendly adsorbents were synthesized using waste polyethylene terephthalate based adsorbent, derived from waste PET bottles, WPET, nano-scale zero valent iron modified adsorbent ... -
Effect of particle shape on bubble-particle attachment behavior: roles of surfaces, edges and vertexes
(Elsevier, 2023)It has been understood through many studies that particle shape is important in terms of particle adhesion to air bubbles in flotation. However, there are many questions yet to be answered. Whether the surface of the ... -
Efficient adsorption of Basic Blue 41 from textile wastewaters by natural and magnetically modified Manisa-Gordes clinoptilolite
(Elsevier, 2021/12/1)A new magnetic zeolite was prepared by the chemical co-precipitation of Fe2+ and Fe3+ in the presence of natural Manisa- G ̈ordes clinoptilolite. The adsorption of Basic Blue 41 (BB41) from aqueous solutions on natural ... -
Evaluating unfairness of popularity bias in recommender systems: A comprehensive user-centric analysis
(Elsevier, 2022)The popularity bias problem is one of the most prominent challenges of recommender systems, i.e., while a few heavily rated items receive much attention in presented recommendation lists, less popular ones are underrepresented ... -
Experimental and Density Functional Theoretical Analyses on Degradation of Acid Orange 7 via UV Irradiation and Ultrasound enhanced by Fenton Process
(Elsevier, 2023)In this study, Acid Orange 7 (AO7) removal from synthetic water by advanced oxidation processes was investigated. Within the scope of the study, individual and different integrated applications of Fenton re- action, ... -
