    The Final Declaration of 3rd National Open Access Workshop (21 October 2014)
    (Turkish Librarians Assoc, 2014) Tonta, Yasar; Gurdal, Gultekin
    The article shares with the public the recommendations of the Final Declaration prepared within the scope of the Third (Turkish) National Open Access Workshop organized by ANKOS (Anatolian University Libraries Consortium), AEKA (ANKOS Open Access and Consortial Archives), YOK (Higher Education Council), and HU BBY (Hacettepe University Department of Information Management). The article urges that as soon as possible the necessary arrangements be made for the acceptance of the free circulation of information-one of the priorities of the European Union's European Research Area. and for the transition to implementation of open access at the national level. important in order to integrate with the Horizon 2020 project.

    Impact of Thermal Mass Oriented Measures Over CO2 Emissions of a Thermally Insulated Low-Rise Apartment Building in Izmir, Turkey
    (Selcuk Univ, 2014) Gercek, Mumine; Arsan, Zeynep Durmus
    Climate change has drawn the attention of many researchers and practitioners to focus on the methods to address the challenges in achieving low-carbon buildings and cities and in future developments. Nevertheless, few studies have explored the impacts of thermal mass applications for the lowest carbon emissions of building operational energy consumption. A comparative study of CO2 emissions due to different wall and floor compositions is presented in accordance with their lifespans for a hot-humid climate site. Aim of this study is to examine the relation between the energy oriented operations and carbon emissions of the building. Firstly, an existing low-rise building in Izmir is selected, then modelled in the dynamic simulation model software DesignBuilder v4 by synchronizing drawings with basic operational principles of the program. Furthermore, various influence factors of building envelope thermal characteristics are selected as follows: type, location, thickness and thermal specifications of materials used by keeping thermal conductivity value constant. At the end, the research presents remarkable influence of thermal mass oriented measures on reducing energy demands and carbon footprints.

    Vision Transformers-Based Deep Feature Generation Framework for Hydatid Cyst Classification in Computed Tomography Images
    (Springer, 2025) Sagik, Metin; Gumus, Abdurrahman
    Hydatid cysts, caused by Echinococcus granulosus, form progressively enlarging fluid-filled cysts in organs like the liver and lungs, posing significant public health risks through severe complications or death. This study presents a novel deep feature generation framework utilizing vision transformer models (ViT-DFG) to enhance the classification accuracy of hydatid cyst types. The proposed framework consists of four phases: image preprocessing, feature extraction using vision transformer models, feature selection through iterative neighborhood component analysis, and classification, where the performance of the ViT-DFG model was evaluated and compared across different classifiers such as k-nearest neighbor and multi-layer perceptron (MLP). Both methods were evaluated independently to assess classification performance from different approaches. The dataset, comprising five cyst types, was analyzed for both five-class and three-class classification by grouping the cyst types into active, transition, and inactive categories. Experimental results showed that the proposed VIT-DFG method achieves higher accuracy than existing methods. Specifically, the ViT-DFG framework attained an overall classification accuracy of 98.10% for the three-class and 95.12% for the five-class classifications using 5-fold cross-validation. Statistical analysis through one-way analysis of variance (ANOVA), conducted to evaluate significant differences between models, confirmed significant differences between the proposed framework and individual vision transformer models (p<0.05\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$p < 0.05$$\end{document}). These results highlight the effectiveness of combining multiple vision transformer architectures with advanced feature selection techniques in improving classification performance. The findings underscore the ViT-DFG framework's potential to advance medical image analysis, particularly in hydatid cyst classification, while offering clinical promise through automated diagnostics and improved decision-making.

    On the Correct Modeling of Flow Characteristics in Double Pipe Heat Exchangers With Inner Dimpled Tube
    (Begell House, inc, 2022) Cobanoglu, Nur; Karadeniz, Ziya H.
    Double pipe heat exchangers (DPHXs), which are made up of two concentric or eccentric ducts, are generally used in industrial applications due to the simplicity of the geometry. Passive heat transfer improvement techniques have been investigated to improve the heat transfer ability of the DPHX by the orientation of flow propagation and changing heat transfer area. Dimpled surfaces are considered as the promising passive heat transfer improvement method because of their low weight, small pressure drop penalty, simple fabrication, and small maintenance costs. Since dimples improve the convective heat transfer by flow reattachment, flow impingement, and upwash flow at the downstream region of the dimples, the correct determination of the flow regime is important for accurate prediction of the heat transfer performance especially in small Re numbers. This numerical study presents a sensitivity analysis on the correct modeling of flow characteristics for the investigation of heat transfer performance of DPHXs working with small Re numbers (Re = 500) in low-temperature applications. The effects of laminar flow and turbulent flow solutions on flow propagation and heat transfer performance have been investigated by developing a transient 3D numerical model. The k - omega model was employed to evaluate the influence of dimples on turbulent flow. A constant temperature (T-c=253.15 K) boundary condition was applied at the inner pipe. Ethylene glycol-water mixture (50:50) enters the annuli at T-i=293.15 K. The influence of the dimpled geometry in annular flow propagation is discussed by considering velocity and temperature distributions at the critical cross-sections of the geometry.
