Best Proximity Point Results For Multivalued Cyclic Mappings On Partial Metric Spaces
Authors: ASLANTAŞ Mustafa
Published: August 2021

Let ∅≠Ŕ,Ś be subsets of a partial metric space (Ω,ϑ) and Ψ:Ŕ→Ś be a mapping. If Ŕ∩Ś=∅, it cannot have a solution of equation Ψς=ς for some ς∈Ŕ. Hence, it is sensible to investigate if there is a point ἣ satisfying ϑ(ἣ,Ψἣ)=ϑ(Ŕ,Ś) which is called a best proximity point. In this paper, we first introduce a concept of Hausdorff cyclic mapping pair. Then, we revise the definition of 0-boundedly compact on partial metric spaces. After that, we give some best proximity point results for these mappings. Hene, our results combine, generalize and extend many fixed point and best proximity point theorems in the literature as properly. Moreover, a comparative and illustrative example to demonstrate the effectiveness of our results has been presented.

Authors: NESLİ Safak , YILMAZ Oğuzhan
Published: August 2021

Additive manufacturing (AM) offers high design flexibilities and challenging approaches to produce highly complicated and intricate parts, which could not be possible to be produced with traditional manufacturing methods. However, one of the significant drawbacks of AM processes is, certainly, poor surface qualities, which are not acceptable for end products. Laser polishing (LP) offers an innovative surface-finishing technique that could be used to reduce the surface roughness. This research presents the fundamentals of the LP process, experiments on the additive manufactured part surfaces and the roughness reduction. An INCONEL 625 part produced by selective laser melting (SLM) was selected as the sample for the LP experiments. The results showed that laser polishing is able to enhance the surface finish and the reduction in surface roughness can become from Ra = 10.91 µm to Ra = 2.347 µm.

Carbon Dioxide Capture Properties of MgCl2 Templated Microporous Carbon from p-toluenesulfonic Acid
Authors: ZAMAN Ali Can
Published: August 2021

Herein, porous carbon materials were prepared using p-toluenesulfonic acid (TsOH) as a carbon source with (TsOH-STC) and without (TsOH-C) presence of MgCl2.6H2O. The products were evaluated in terms of CO2 (carbon dioxide) adsorption performance, texture and surface chemical structure. Both samples contain oxidized sulfur on their surface according to X-ray photoelectron spectroscopy (XPS). TsOH-STC has a 3D porous network, but TsOH-C consists of a dense structure. It was understood that TsOH-C is not suitable to be analyzed with N2 adsorption at cryogenic temperatures probably due to restricted access to narrow pores due to lack of external surface. The CO2 uptakes are 0.78 mmol g-1 for TsOH-C and 0.67 mmol g-1 for TsOH-STC at flue gas conditions (0.15 bar and 298 K) of coal fired power plants, which is a projection of ultramicropore (pores smaller than 0.7 nm) volume in 0.5 nm range. TsOH-C has CO2 uptake capacity of 2.21 mmol g-1 and TsOH-STC reaches 2.47 mmol g-1 at 1 bar at 298 K. Maximum CO2 adsorption enthalpy (Qst) value for TsOH-C is 24.9 kJ mol-1 and that of TsOH-STC is 25.7 kJ mol-1. IAST (ideal adsorbed solution theory) selectivities (CO2:N2 = 15:85) of the samples are 13.5 for TsOH-STC and 19.7 for TsOH-C at 1 bar. It was shown in this study that salt templating with MgCl2 does not influence ultramicroporosity development and provide moderate level CO2 capture performance. However, templating induces formation of supermicropores (micropores larger than 0.7 nm), large mesopores and macropores on TsOH derived carbons.
A Fuzzy Logic Approach on the Evaluation of Driving Styles and Investigation of Drivability Calibration Effects
Authors: AKSIT Samet , YAVUZ Akif , ŞEN Osman Taha
Published: August 2021

Increased customer expectations lead the automobile manufacturers to develop innovative solutions, such as mode selection functions that provide different performance and comfort settings for the drivers. Almost all brands have different types of driving modes installed on their vehicles, such as sport mode, economy mode, off-road mode, etc. In the current technology, the mode selection is manually done by the driver. Thus, no effort is taken to match the driver style with available driving modes. However, driving mode selection should be done through an intelligent system such as vehicle control unit, in order to optimize customer expectations related to vehicle performance, driving comfort, and fuel consumption. This can be achieved by the analysis of all drivability maneuvers during any driving cycle. Based on the results of these analyses, drivability calibration settings of the vehicle can be adjusted depending on driver behaviors. In addition, fuel consumption can be improved using suitable calibration for each driver type. In this study, an experimental investigation is carried out in which vehicle data is collected for eleven different drivers at three different drivability calibrations. Furthermore, fuzzy logic algorithms are utilized in order to distinguish the driver characteristics. First, data from nine drivers are used in order to train the fuzzy logic approach. Then, the trained fuzzy logic scheme is used to assess the characteristics of two other drivers, who were left out in the training data set. Hence, it is aimed to obtain an intelligent prediction procedure that can estimate the characteristics of a driver based on their driving styles.

Published: August 2021

The transient and dynamic performance analysis of a proposed line-start, three-phase concentrated dual-winding synchronous reluctance motor (cDWSynRM) in comparison with the conventional concentrated winding synchronous reluctance motor (cSynRM) was presented. Both windings are overlapping windings. The cDWSynRM consist of main and auxiliary windings with capacitive assistance for power factor improvement. The modelling of the synchronous reluctance motors (SynRM) was done in direct-phase variables considering only the fundamental magneto-motive force (MMF). The machine inductances of both machine models were determined using winding function theory (WFT). These derived inductances were used to determine machine performance characteristics such as Torque, Speed, Phase currents etc. The performance characteristics of both motors were monitored using MATLAB/Simulink, and the proposed line-start cDWSynRM with capacitive assistance was observed to have improved performance characteristics when compared to the cSynRM.
