Artificial Intelligence Based Resource Allocation in Cell-Free Networks

Mert Demirel

With the rapid development of technology, cellular networks can no longer meet the demands of wireless networks. Communication systems need to be updated to ensure that every user equipment (UE) receives accurate and efficient service. Cell-free (CF) networks offer advantages over cellular networks, such as more flexible resource allocation, higher capacity, better coverage and lower interference. The deployment of multiple access points (APs) and flexible allocation of resources leads to higher network performance and efficiency. In addition, in CF networks, users can communicate with ...Daha fazlası

EXPLORING THE EFFECT OF PLACE ATTACHMENT ON THE IMPACTS OF TOURISM TO DETERMINE SIVAS RESIDENTS’ SUPPORT FOR TOURISM DEVELOPMENT

Furkan Atasoy KARACABEY

Residents’ perceptions of tourism impacts and their attitudes toward tourism development are among the topics that are frequently examined in the tourism literature. In particular, it is of great importance to determine the perceptions of the residents in the destination where tourism activities are not intense and tourism is not developed yet, in terms of ensuring sustainable tourism development in the destination. Therefore, this study aims to use two different structures (place attachment and the impacts of tourism) together to determine the intention of supporting tourism developments and ...Daha fazlası

Optimization of Drying Process of Plastic Granules Based on Stochastic Method with Neuro Regression Approach

Mustafa DİNÇ

Polymers contain moisture due to their chemical structure. Moisture in polymers is important for the quality of the final product and ease of processing. For this reason, polymers are subjected to drying before processes such as injection and extrusion. Drying is carried out at temperatures and times specified by the polymer suppliers. Over-drying leads to increased viscosity (processing difficulty) while under-drying leads to flow marks, burrs, and reduced tensile strength and impact strength. Over-drying also causes excessive energy consumption. In this study, the drying process optimization ...Daha fazlası
