Evaluation of ski centers’ performance using multiple-criteria decision-making methods

Burcu ORALHAN | Zeki ORALHAN | Nur KIRDÖK

Introduction. This study aimed to determine the criteria for the choice of nine different leading ski centers that serve actively in the ski tourism sector of Turkey, to calculate the criteria weights, and to measure the performance of these centers. Material and methods. In this context, the data were defuzzified using the CFCS method, and the fuzzy DEMATEL method was used to determine the criteria affecting the choice of ski centers. Then, the TOPSIS method was applied to measure the performance of ski centers by using the criteria weights obtained with the fuzzy DEMATEL method. Results. As ...Daha fazlası

Error analysis of the joint localization and synchronization of RIS-Assisted mm-Wave MISO-OFDM under the effect of hardware impairments

Büşra CENİKLİOĞLU

This work investigates the theoretical bounds of the joint localization and synchronization processes in a reconfigurable intelligent surface (RIS)-assisted system. We address the case of millimeter-wave (mm-Wave) multiple-input single-output (MISO) orthogonal frequency-division multiplexing (OFDM) with non-ideal transceivers. Considering a single antenna mobile station (MS) aims to estimate the parameters of the downlinks from the base station (BS) and the RIS by observing a known sequence received by the MS directly from the BS and indirectly through the RIS. The theoretical bounds of the es ...Daha fazlası
