    Comparative Analysis Of Patch Antennas With Rectangular Slots For Laminate And Wearable Materials At 5g Networks
    (Institute of Electrical and Electronics Engineers Inc., 2024) Hakanoglu, B.G.; Agaya, E.; Gulmez, G.; Yalinsu, S.
    In this study, new multi-band patch antenna design models are proposed for use in 5G networks. The purpose of the designs is to open rectangular slots on rectangular shaped patch antennas and bring them to the desired operating conditions with parametric analyzes. The designs were carried out by following the same procedure steps using five different dielectric laminate substrate materials, such as RO3003, RT6006, FR4, RO3203, RO6010, and one denim fabric base material. The antennas were compared in terms of return loss, gain and radiation characteristics. Except for the antenna designed with RO3203 at certain values of rectangular slots, radiation at multiple frequencies was obtained at 5G frequencies. With the proposed method, improvement was observed for return loss and bandwidth characteristics in the RO3203 based antenna. This study will be a resource for antenna researchers by revealing the responses of different substrate materials to the same design method for 5G bands in patch antennas. © 2024 IEEE.

    Miniaturized 2.4 Ghz Antenna Design for Uav Communication Link;
    (Institute of Electrical and Electronics Engineers Inc., 2020) Yilmaz,V.S.; Kara,A.; Aydin,E.
    In many communications applications, unlike conventional antennas, lightweight, flexible, small antennas that can adapt to mechanical and industrial constraints are required. In this study, the results of antenna design operating at 2.4 GHz are presented for use in Unmanned Aerial Vehicle (UAV) tele command links. In the parametric and optimization studies carried out on the antenna, it is aimed to increase the gain while keeping the size as small as possible. The requirements of the industry, such as light, aesthetics, miniature and high gain aspects of the antenna were targeted in the design process. Finally, an antenna of 55.2x88 mm size and 7dB gain was achieved using commercial electromagnetic design tools. The designed antenna become satisfying industrial requirements with these features. © 2020 IEEE.

    Informatics Engineering Education in Turkey and Expectations of Software Industry;
    (Institute of Electrical and Electronics Engineers Inc., 2018) Yazici,A.; Mishra,A.; Karakaya,Z.; Ustunkok,T.
    In this study, using the ÖSYM data, the number of intakes in Informatics Engineering programs in Turkey, accreditation data and the medium of instruction of the program are summarized for the years 2016 and 2017. In addition, the software sector's expectations from the informatics engineering graduates are reassessed based on the academic studies. The developed knowledge-skill gap set was used to evaluate the situation in Turkish informatics engineering programs. Sector expectations are discussed in the context of 2017-2019 Turkey Software Sector Strategy and Action Plan prepared by the Ministry of Science, Industry and Technology of Turkey and some proposals are made for the academia. As a result, it was observed that the expectations of the software industry were similar in all studies. Additionally, the expectations were changed in the direction of developing technologies and this change should be reflected in the informatics engineering programs. © 2018 IEEE.

    Use of Cloud Computing Applications in Reference Services;
    (University and Research Librarians Association (UNAK), 2014) Tavluoʇlu,C.; Korkmaz,A.
    Cloud computing is a computing platform that allows access the information over internet by using desktop computers, laptops, tablet PCs and smart phones without any software and storage unit. Many organizations use this technology and save time and money, such as libraries. Libraries have been adopting their reference services to the new technology and library services have been moving to the cloud. This paper defines cloud computing, presents the opportunities and challenges, also include how to use cloud based applications in reference services. A survey was applied to identify the use of cloud based Software as a Service (SaaS) models by references librarians who work at university libraries in Ankara. According to results, the degree of usage of this tools generally low.

    University Libraries Staff-User Relationship and the Conformity of the Current Situation To the Standard
    (Turkish Librarians Assoc, 2017) Kaya, Huseyin
    University libraries are one of the most important units in universities that aim to provide the best service to their users. Because it is their libraries that guide to the universities where science is produced therefore, human resources in the university libraries have the same equal importance. In order to provide better service in the university libraries, one of the indispensible element is to have certified librarians who are expert on their topics. In this research, the evaluation of the relationship between the number of staff that the foundation & the public libraries has and the number of users they have and the number of staff with the librarianship degree have been made. In addition, number of users and staff standard in the work called "University Libraries in Turkey towards 2023, Current Situation, Problems, Standards and Solution Proposals" and suitability of the data to the standards that the resarcher has currently have been examined. A total of 74 university libraries, including 55 state and 19 foundation university libraries, participated in the work. The total number of staff and the number of staff with the librarianship degree are given in the data obtained. All the data obtained has been evaluated separately for public and foundation university libraries. As a result of the study, While the number of librarians in total staff in the state university libraries is 40.9 %, this figure is 56.9 % in the foundation university libraries. When compared to the standard prepared by YOK (Council of Higher Education) and the data of 74 university libraries, it is seen that university libraries are inadequate in terms of staff. In particular, there are no librarians in some foundation university libraries. Attention should be paid to personnel management in the university libraries to address this issue. In addition, the relevant state institutions and related associations should be informed.

    Public Policies and Social Movements: The Implications of Protest Movements on Mining Policy in Turkey
    (Ankara Haci Bayram veli Univ, 2010) Ozen, Hayriye; Ozen, Suekrue; Department of Public Administration and Political Science
    This article proposes that public policy and social movements literatures can help each one another achieve for a better understanding of the role of social movements in the process of public policy formation. In order to illustrate this suggestion, taking insights from both types of literatures, we investigate how and to what extent the anti-gold-mining protest movements in Izmir-Bergama, Usak-Esme, Izmir-Efemcukuru, and Canakkale-Balikesir have influenced the mining policy in Turkey since 1985. The results indicate that a centralized policy-making tradition can influence atin what stage of the policy-making process protest movements emerge, and what kindssorts of tactics are pursued. The results also show that the repressive attitude against the protest movements adopted by an advocacy coalition formed between the governments and multinational companies to further enforce the existing policy, can lead to the growth of thegrowing opposition against the existing policy through the emergence of new protest movements.
