Article Citation - WoS: 3Citation - Scopus: 5Assessing Community Awareness for Participatory Conservation of Cultural Heritage: the Case of Tepebağ Tumulus and Its Surroundings in Adana Turkey(Emerald Group Publishing, 2022) Umar, Nur; Yüceer, Hülya; Aydın, RozelinPurpose: The purpose of this paper is to identify the levels of awareness of locals about conservation and cultural heritage, in order to develop suggestions and methods for them to participate in these processes. Design/methodology/approach: The method of research is based on face-to-face surveys, mainly questionnaires that were conducted with 1,200 local people. The data obtained was evaluated using the SPSS 25.0.0 V program. Findings: The results show that locals mainly find appropriate the assets that reflect their culture but disregard archaeological remains. The participation of locals in the conservation process will end up benefiting them economically. Social implications: It is currently accepted that effective conservation cannot be achieved unless its technical considerations are considered together with social and cultural aspects. Ensuring the participation of local people in the conservation process has proved to be important in the development of holistic and sustainable outcomes. In places, where multilayered cultural heritage exists and local residents are from different cultural backgrounds, a detailed assessment of cultural heritage perception that involves local people gains significance. Originality/value: It is project-based in the sense of adding the dimension of community awareness to the practice of cultural heritage conservation in the multilayered and multicultural places.Article Citation - WoS: 2Citation - Scopus: 3Model-Based Detection and Isolation of the Wheel Slippage and Actuator Faults of a Holonomic Mobile Robot(Emerald Group Publishing, 2022) Şahin, Osman Nuri; Dede, Mehmet İsmet CanPurpose: Mobile robots may perform very critical tasks under difficult operating conditions. Faults encountered during their tasks may cause the task to be interrupted or failed completely. In the active fault tolerant control methods, it is very important not only to detect the faults that occur in the robot, but also to isolate these faults to develop a fault recovery strategy that is suitable for that specific type of fault. This study aims to develop a model-based fault detection and isolation method for wheel slippage and motor performance degradation that may occur in wheeled mobile robots. Design/methodology/approach: In the proposed method, wheel speeds can be estimated via the dynamic model of the mobile robot, which includes a friction model between the wheel and the ground. Four residual signals are obtained from the differences between the estimated states and the measured states of the mobile robot. Mobile robot’s faults are detected by using these signals. Also, two different residual signals are generated from the calculation of the traction forces with two different procedures. These six residual signals are then used to isolate possible wheel slippage and performance degradation in a motor. Findings: The proposed method for diagnosing wheel slip and performance degradation in motors are tested by moving the robot in various directions. According to the data obtained from the test results, a logic table is created to isolate these two faults from each other. Thanks to the created logic table, slippage in any wheel and performance degradation in any motor can be detected and isolated. Originality/value: Two different recovery strategies are needed to recover temporary wheel slippage and permanent motor faults. Therefore, it is important to isolate these two faults that create similar symptoms in robot’s general movement. Thanks to the method proposed in this study, it is not only possible to isolate the slipping wheel with respect to the non-slipping wheels or to isolate the faulty motor from the non-faulty ones, but also to isolate these two different fault types from each other.Article Citation - WoS: 5Citation - Scopus: 4A Quantitative Approach for Evaluating Intervention-Value Relations: Historic Mosques of Manisa, Turkey(Emerald Group Publishing, 2021) Büyükkılıç Koşun, Suna; Hamamcıoğlu Turan, MinePurpose This study aims to propose a systematic way of evaluating the impact of historic and current interventions on cultural asset values of monuments that have preserved their authentic functions so that future interventions can be better guided. Design/methodology/approach The study focuses on the Mosque typology. The case studies are chosen from a region that has a rich historic background, but has generally undergone rapid urbanization and faces extensive restorations today. Conventional site survey, archive and historical research and visual analysis are made, but the evaluation process has been designed. As a result, scale and intensity of interventions and disasters and the vulnerability of the monument should be identified for each period of the asset. Variations in the intensity of esthetic or historic qualities and the environmental settings should be credited, rather than the utilitarian necessities. Findings Mosques and their environs are most vulnerable in terms of their architectural authenticity and site aesthetics. Originality/value The objects studied in the previous studies present a variation, but the majority of the work is carried out with conventional evaluation methods with the emphasis on building scale. However, the mosques are affected by the interventions and disasters, not only as single architectural entities but also as the focal elements of their neighborhoods. So, the intervention-value relations should be understood both for building and site scales. An evaluation process is proposed for understanding the change of values with respect to interventions and disasters throughout history by combining qualitative and quantitative techniques.
