Book Part Common Fixed Point Results for Meir-Keeler-Type Contraction Mappings(Springer, 2025) Karapńar, Erdal; Cvetković, Marija, S.; Yeşilkaya, Seher SultanMeir–Keeler contraction presents an interesting and widely studied topic in the area of Metric Fixed Point Theory. We intend to present several results concerning common fixed problem and the impact of Meir-Keeler-type contractions on this type of results. We will present results on common fixed problem for a Meir–Keeler contraction mapping in various settings—metric space, b-metric space, partial metric space, Branciari metric space, etc. It is our intention to present a comprehensive study on this topic that will present a good starting point for the researchers in the Fixed Point Theory. © 2025 Elsevier B.V., All rights reserved.Conference Object Citation - WoS: 2Object-Oriented Inheritance Metrics: Cognitive Complexity Perspective(Springer-verlag Berlin, 2009) Mishra, Deepti; Mishra, AlokIdentifying high cognitive complexity modules can lead to a better quality software system and can help during maintenance also. It has been found that inheritance has an impact on cognitive complexity of a software system. In this paper, two inheritance metrics based on cognitive complexity, one at class level CCI (Class Complexity due to Inheritance) and another at program level ACI (Average Complexity of a program due to Inheritance), have been proposed for object-oriented software systems. These metrics are also compared with other well known object-oriented inheritance metrics.Article Citation - WoS: 56Best Proximity Point on Different Type Contractions(Natural Sciences Publishing Corp-nsp, 2011) Karapinar, Erdal; Erhan, Inci M.In this manuscript, some proximity points are obtained by using different types cyclic contractions. Also, generalized cyclic Meir Keeler contraction is introduced and a new fixed point theorem for this cyclic mapping is stated.Article A Comprehensive Study of Space Efficiency in Tall Buildings: The Australian Perspective(Kauno Technologijos Universitetas, 2025) Ilgın, H.; Aslantamer, Ö.Spatial efficiency in Australian towers is shaped by a multifaceted interaction of many parameters such as architectural and structural considerations. However, there are no comprehensive studies available on space utilization in Australian high-rise towers. The article addresses this gap by investigating 32 case studies. This study aims to investigate how contemporary Australian tall buildings achieve spatial efficiency by analyzing the relationship between architectural and structural parameters and internal usable area ratios. Key findings: residential function, centrally-located core layouts, and prismatic arrangements are the most widespread trends; concrete is the favored construction material, with the shear-walled frame system being the most commonly used structural system; average space efficiency is 82%, with a core-to-GFA ratio of 16%. The paper offers valuable understandings for construction experts to inform design decisions in high-rise construction projects within the Australian context. © 2025, Kauno Technologijos Universitetas.

Then, we investigated whether Free-Players have any impact on the persistent and stable cooperative behavior of the Players in the context of two dimensional spatial Prisoner’s Dilemma game environment. In simulations, two different Player strategy update setups are considered: State-based Majority and Payoff-driven Stochastic. The results for both setups showed that Free-Players have impact on global cooperative behavior of the system. According to the obtained State-based Majority setup results, the increased number of Free-Players has no direct regulative impact on the control of global cooperative behavior of the proposed system. For the Payoff-driven Stochastic strategy update setup, the increased number of Free-Players has an observable regulative impact on the control of global cooperative behavior of the proposed system. However, the net effect of Free-Players on the cooperativeness of the environment was only in the range 0.007 < Net_Coop(α, β) < 0.036 while the attained cooperation ratio results are mostly not sensitive to the initial cooperation ratios. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.Article Citation - Scopus: 2On the Novelty of “Contracting Perimeters of Triangles in Metric Space”(Erdal Karapinar, 2025) Karapınar, E.In this note, we investigate whether the newly introduced notion of “contracting perimeters of triangles” in the context of standard metric spaces is novel or equivalent to “a variant” of Banach contraction in the setting of G-metric spaces. By using the fact that G-metric spaces are equivalent to quasi-metric spaces, we reconsider our main question as whether the fixed-point theorems via “contracting perimeters of triangles” is equivalent to a fixed point of the same mapping in the context of quasi-metric spaces. © 2025, Erdal Karapinar.

The recent release of the "EASA AI Roadmap 2.0"by the European Union Aviation Safety Agency (EASA) underscores the growing impact of AI on aviation, driving the emergence of new business models and emphasizing a human-centric approach to AI integration within the aviation industry. This study addresses a significant gap in the literature by examining student pilots' perspectives on AI, specifically focusing on AI trustworthiness, attitudes, anxieties, and adaptation performance. The study utilizes a quantitative research approach, collecting data from 150 student pilots through surveys. Preliminary results from 106 respondents indicate varied attitudes toward AI, with significant implications for AI-supported cockpit assistant systems and the broader aviation industry. The study sample consisted of 106 (Mage = 23.6, SDage= 4.64; 79% male) student pilots from of university pilot training departments and various flight school in Turkey. Collected data were analyzed on SPSS 29. The study revealed that Sociotechnical Blindness AI anxiety is a significant predictor of general attitudes toward AI among student pilots. This finding suggests that higher levels of anxiety related to the perceived complexity and potential unintended consequences of AI are associated with more positive general attitudes toward AI. The findings emphasize the need for a human-centric approach to AI integration, highlighting the importance of trust, transparency, and adaptive training in the successful adoption of AI technologies in aviation. © 2024 The Authors. Published by ELSEVIER B.V.Conference Object Citation - Scopus: 5A new complexity metric based on cognitive informatics(2008) Misra,S.; Akman,I.In this paper, a new complexity metric based on cognitive informatics is proposed for object oriented(OO) code. This is the single metric, which covers cognitive complexity of the OO system, method complexity and complexity due to inheritance together. The proposed metric was evaluated against Weyuker set of measurement principles. It was found that seven Weyuker properties are satisfied by this measure. © 2008 Springer-Verlag Berlin Heidelberg.Article Citation - Scopus: 1The Effect of a 6-Week Balance Exercise Program on Balance Parameters in Frailty Syndrome: a Randomized Controlled, Double-Blind, Prospective Study(Georgian Association of Business Press, 2023) Karagül, S.; Kibar, S.; Ay, S.; Evcik, D.; Ergin, S.Objective: This study assessed the effectiveness of a six-week balance exercise program on balance parameters and fall frequency in geriatric patients with frailty syndrome. Methodology: This randomized prospective study evaluated a total of 216 patients after referral to a physical medicine and rehabilitation outpatient clinic. Participants were divided into group 1 (flexibility exercises) and group 2 (balance exercises, including kinesthetic ability trainer [KAT] balance exercises, and flexibility exercises). Both groups performed exercises five days per week for six weeks. Balance assessments included the Berg Balance Scale and time-up-and-go test to evaluate dynamic and functional balance, while the one-leg stand test and KAT 4000 static balance test were done to evaluate static balance. Results: Frailty was observed in 37 patients (17.12%). Patients without frailty syndrome initially performed significantly better (p <0.001). Group 2 demonstrated statistically significant improvements after six weeks (p <0.05). Conclusion: Long-term exercise programs improve balance parameters and exercise performance in older adults with frailty. © 2023 Georgian Association of Business Press. All rights reserved.
