Article Citation - Scopus: 11A Novel Planar Scissor Structure Transforming Between Concave and Convex Configurations(WITPress, 2017) Yar, Müjde; Korkmaz, Koray; Kiper, Gökhan; Maden, Feray; Akgün, Yenal; Aktaş, EnginIn this paper, a novel two-dimensional scissor structure that transforms between concave and convex configurations is presented. The structure is designed by a method of assembling kite or anti-kite loops in the flat configuration. Angulated units are generated from the assembled loops. Finally, a new angulated scissor unit is introduced in order to design the novel scissor structure.Article Citation - Scopus: 9Design Alternatives of Network of Altmann Linkages(WITPress, 2017) Atarer, Fulya; Korkmaz, Koray; Kiper, GökhanThis paper presents a method of building deployable network assemblies derived from the single degree of freedom (DoF) over constrained Altmann linkage as a basic module. The method is based on assembling linkages with common links and joints or overlapping with extra R or 2R joints. New loops are emerged with overlapping method. The networks created have a single DoF, are over-constrained and have both fully deployed and folded configurations. The computer-aided models (CAD) are used to demonstrate these derived novel mechanisms.Conference Object Citation - Scopus: 1Evaluation of the Conservation Activities in the Historical Settlement Tenedos-Bozcaada Island(WITPress, 2011) Akpınar, Figen; Saygın, Nicel; Karakaya, EmelThe efforts for the conservation of cultural heritage in historical settlements are a highly problematic and multi-faceted issue in Turkey. Although the conservation legislation dates back 50 years, the cultural heritage has not been internalized and not accepted in wider parts of the society and, has not found a solid political base. The historical and cultural heritage areas are mostly marketed for tourism and turned into places as the simulacrum of the elitist and middle class tastes. Tenedos (Bozcaada) Island inherits the rich cultural heritage of two millennia. The Island is in danger of losing its social, cultural and multi-ethnical characteristic where Turkish and Greek societies live harmoniously. The architectural, economic and ecological values are also in danger because of the rise of touristic activities and the construction of vacation homes as well as the State's withdrawal to provide subsidy to the agricultural sector that took place after the 1980s in parallel with the general economic policies adopting global economic restructuring. The objective of the paper is to highlight the multidimensional character of the social and spatial process which is enmeshed in the conservation activities of the Island. The values and norms, social, economic considerations in the conservation activities need a new approach and, without existence of a common will and a wider participation of the society it is hard to expect any success in the conservation of the rich cultural values, and to assess, develop and carry them into the future. A bundle of techniques are used: a large survey analysis of the area is realized and its social, historical and physical characteristics are documented. Questionnaires, in-depth interviews are used in order to detect the difficulties for conservation of the heritage in part of the responsible public bodies. The public and tourism sector opinions, thoughts and aspirations are surveyed. Even though, the preservation of Tenedos Island's cultural heritage appears to be a difficult challenge, there seems to be some positive clues for the future. © 2011 WIT Press.Conference Object A Data Coding and Screening System for Accident Risk Patterns: A Learning System(WITPress, 2011) Geçer Sargın, Feral; Geçer Sargın, Feral; Duvarcı, Yavuz; Duvarcı, Yavuz; İnan, E.; İnan, E.; Kumova, Bora İsmail; Kumova, Bora İsmail; Atay Kaya, İlgi; Atay Kaya, İlgiAccidents on urban roads can occur for many reasons, and the contributing factors together pose some complexity in the analysis of the casualties. In order to simplify the analysis and track changes from one accident to another for comparability, an authentic data coding and category analysis methods are developed, leading to data mining rules. To deal with a huge number of parameters, first, most qualitative data are converted into categorical codes (alpha-numeric), so that computing capacity would also be increased. Second, the whole data entry per accident are turned into ID codes, meaning each crash is possibly unique in attributes, called 'accident combination', reducing the large number of similar value accident records into smaller sets of data. This genetical code technique allows us to learn accident types with its solid attributes. The learning (output averages) provides a decision support mechanism for taking necessary cautions for similar combinations. The results can be analyzed by inputs, outputs (attributes), time (years) and the space (streets). According to Izmir's case results; sampled data and its accident combinations are obtained for 3 years (2005 - 2007) and their attributes are learned. © 2011 WIT Press.Conference Object Visualisation and Evaluation of Structural Characteristics and Problems of a Classical Ottoman Bath(WITPress, 2003) Çizer, Özlem; Turan, MineVisual documentation has been accepted as an important phase of architectural heritage conservation. Visualisation of structural characteristics and their problems, however, has gained importance in the last decade. In this study, structural characteristics are used to comprehend the characteristics of construction techniques and materials of building components. Structural failures such as loss of a structural element and cracks, and material deterioration such as loss of material and deposit are the main problems observed. Visualisation of structural characteristics and their related problems has been the basis of the methodology in this study. It is also considered important to underline the necessity of the design of a special visualisation technique peculiar to the characteristics of the monument under study.Conference Object Citation - WoS: 1Citation - Scopus: 1The Method of Policy Capturing for the Transportation Disadvantaged: Simulation Results(WITPress, 2003) Duvarcı, Yavuz; Gür, GüneşIn the previous study called "A Modelling Approach for the Transportation Disadvantaged", which was an experimental one calibrated in a small town in Turkey, it was observed that an integrated TPM for the disadvantaged category was probable, and the findings were observable at all stages of the sequential modelling, however, with slight differences compared to the Normal model's results. Following the previous one, this study shows the method of how "policy capturing" could be possible on the basis of these differences, which aims to help improve the adverse conditions of the disadvantaged. The method is sort of category analysis based on the cluster analysis results, since it is clearly verified that the "disadvantage indices" identified as the single-disadvantage groups match with the values of cluster centres. Using TRANUS software, three simulations are run for three dimensions of disadvantage: socio-economic (categorical), spatial and the positional. The simulation results, evaluated from different criteria, showed that socio-economic dimension was the most fruitful area for policy capturing.
