Editorial 17th International Conference on Mechatronics Technology, October 15-18, 2013, Jeju Island, Korea(Elsevier, 2015) Hwang, Sung Ho; Kim, Joon-wan; Dorantes-Gonzalez, Dante JorgeIn recent years, Mechatronics has gained a lot of interest as more applications have been introduced to industry and society. The need for new mechatronic technologies in the form of advanced production systems, mechatronic devices, control systems, robotics, biomedical applications, MEMS, and measurement systems, among others, is very much required in improving productivity and competitiveness in many industries. Thus, this conference was organized to address the state-of-the-art technology for the benefit of researchers and users, and this time the conference made a special focus on the topic: Sustainable Mechatronics Technology.Book Part Citation - Scopus: 518 - Acoustic and Mechanical Properties of Biofibers and Their Composites(Elsevier, 2022) Koç, Büşra; Genç, Garip; Körük, HasanIn this study, the acoustic and mechanical properties of many biofibers and their composites are presented. First, the sound absorption coefficients and transmission losses of commonly used natural fibers and their composites are presented, by clearly reporting the thickness of the samples, for three different frequency ranges (<500 Hz: low, 500–2000 Hz: medium, and >2000 Hz: high). In addition, the sound absorption coefficients (for low- and medium-frequency ranges) and noise reduction coefficients of some 40-cm-thick samples are overlaid in order to directly compare their performances. Second, the physical properties, such as the density, diameter, and length of biofibers, and mechanical properties, such as the damping (or loss factor) and Young’s modulus of biofibers and their composites, are presented in detail. For comparison purposes, the acoustic and mechanical properties of some conventional materials, such as carbon and glass fibers, are included in the tables and figures. Finally, the effects of some parameters, such as pretreatment, fiber diameter, fiber/matrix ratio, moisture content, manufacturing and machining parameters/techniques, and measurement conditions/methods, on the acoustic and mechanical properties of natural materials are presented. Furthermore, current applications and potential usage areas of natural fibers are briefly discussed.Book Part Citation - Scopus: 319 - Identification of the Elastic and Damping Properties of Jute and Luffa Fiber-Reinforced Biocomposites(Elsevier, 2022) Genç, Garip; Saygılı, Yusuf; Körük, Hasan; Şanlıtürk, Yusuf KenanAlthough there are many studies in the literature on the static mechanical properties of biomaterials such as tensile strength, the dynamic mechanical properties of biomaterials such as modal loss factors have not been investigated in detail. In this study, the Young’s moduli and damping (or loss factors) of some jute and luffa fiber-reinforced biocomposites are investigated. The effects of fiber/resin ratio and thickness on the mechanical properties of the jute and luffa composites are identified via an experimental approach. For this purpose, acoustic and structural frequency response functions of some homogeneous and hybrid jute and luffa composite plates with different fiber/resin ratios and thicknesses are measured. By analyzing the measured frequency response functions using the circle-fit method, the modal frequencies and loss factors of the homogeneous and hybrid composite plates are determined. By assuming that the homogeneous plates are isotropic, the same plates are modeled using the finite element method, and by comparing the experimental and theoretical natural frequencies, the elastic properties of the homogeneous plates are determined. In addition, the same homogeneous plates are modeled by considering an anisotropic material model, and the associated material properties are determined. By using the identified material properties, the finite element models of the hybrid composite plates are developed, and by comparing their experimental and theoretical natural frequencies, the identified elastic material properties are evaluated and validated.Conference Object 1980’lere Nasıl Bakabiliriz?

Sosyal güvenlik sistemleri, sosyal riskle karşılaşan insanların ya da belirli durumlarda yakınlarının zararlarının karşılanmasını sağlayan bir fonksiyona sahiptir. Bir sosyal güvenlik tekniği olan ve zorunluluk unsuru içeren sosyal sigortalar, sosyal güvenliğin sağlanmasında en yaygın kullanılan yöntemdir. Çalışma hayatında iş kazası, meslek hastalığı ya da işsizlik gibi risklerle sürekli karşı karşıya olan işçilerin sosyal sigortalılığının sağlanması da büyük önem arz etmektedir. İş sözleşmesi ile çalışanların sosyal sigortalılığı 5510 sayılı Kanun'un 4/1-a bendi kapsamında düzenlenmiştir. Bununla birlikte Kanun koyucu bir iş sözleşmesi ile çalışmıyor olsalar dahi bazı kişi gruplarını insani ve sosyal düşüncelerle 4/1-a sigortalı saymıştır. Bu çalışmada iş sözleşmesi ile çalışanların ve Kanun'un 4/1-a bendi kapsamında saydığı diğer kişilerin sigortalılığı, öğreti ve içtihatlardan da yararlanılarak ele alınmıştır.Article 7146 Sayılı Kanunla Gelen Bedelli Askerlik ve Kıdem Tazminatı(Seçkin Yayınevi, 2018) Akyiğit, Ercan7146 Sayılı kanunla getirilen hüküm ; işçi iş sözleşmesini 7146 sayılı kanunla getirilen bedelli askerlik yüzünden fesederse kıdem tazminatı alamaz.Article Citation - WoS: 2Citation - Scopus: 1A Benchmark Dataset for Turkish Data-To Generation(Elsevier, 2022) Demir, Şeniz; Öktem, SezaIn the last decades, data-to-text (D2T) systems that directly learn from data have gained a lot of attention in natural language generation. These systems need data with high quality and large volume, but unfortunately some natural languages suffer from the lack of readily available generation datasets. This article describes our efforts to create a new Turkish dataset (Tr-D2T) that consists of meaning representation and reference sentence pairs without fine-grained word alignments. We utilize Turkish web resources and existing datasets in other languages for producing meaning representations and collect reference sentences by crowdsourcing native speakers. We particularly focus on the generation of single-sentence biographies and dining venue descriptions. In order to motivate future Turkish D2T studies, we present detailed benchmarking results of different sequence-to-sequence neural models trained on this dataset. To the best of our knowledge, this work is the first of its kind that provides preliminary findings and lessons learned from the creation of a new Turkish D2T dataset. Moreover, our work is the first extensive study that presents generation performances of transformer and recurrent neural network models from meaning representations in this morphologically-rich language.Conference Object A bridge “Maybe” too far: Granting legal personality to animals?(University of Antwerp, 2021) Başoğlu, Başak; Kapancı, Kadir BerkTurkish legal system, like all other legal systems is developed by persons and thus, the >main distinction is made between persons and objects (persona and res). According to thistraditional distinction, animals which are not humans but being “other” species in our World,have mostly been considered as objects and thus subject to personal property. In these personorientedlegal systems, including the Turkish one, even the rules relating to animals essentiallyaims to protect the owner of the animals, but not the animals themselves.However, today this paradigm is slowly challenged as “right to life” (to some extent) isgranted to animals under many legal systems (for instance under the Turkish Law on Protectionof Animals dated 24 June 2004). Nevertheless, the boundaries of this right are the interests ofthe people. Unfortunately, the concepts of animal dignity and right to life do not provide enoughprotection to animals. But what could be the solution to better protect the animals? Grantinglegal personality to the animals? Perhaps it is a bridge too far…Throughout the history, personality have been granted to different objects if it isbeneficial and feasible to do so. Accordingly, this paper firstly aims to evaluate whether it isbeneficial and feasible to grant legal personality -partially or as a whole- to the animals. Underthis first sub-title we will discuss as well whether granting to each and every animal a separatepersonality or a sole conceptual one to the entire nature including the animals. Secondly ourwork further targets to reconsider the traditional distinction of persons and things to provide amore specific legal status for animals. Perhaps such a reconsideration could enable us to solveanother controversial issue of our contemporary world: that is the legal status of “strong”artificial intelligence. Moreover, our discussions will comprise the analyse of the legal statusof the “ancient roman law’s slave”, considered as an object though a human being, benefitingfrom different types of legal protection at different levels, at different times. Across the saidcomparisons, at the end, we would like to reach a robust conclusion.Book Part Article Citation - WoS: 18Citation - Scopus: 22A Capacitated Lot Sizing Problem With Stochastic Setup Times and Overtime(2019) Jabali, Ola; Gendreau, Michel; Jans, Raf; Taş, DuyguIn this paper, we study a Capacitated Lot Sizing Problem with Stochastic Setup Times and Overtime (CLSPSSTO). We describe a mathematical model that considers both regular costs (including production, setup and inventory holding costs) and expected overtime costs (related to the excess usage of capacity). The CLSP-SSTO is formulated as a two-stage stochastic programming problem. A procedure is proposed to exactly compute the expected overtime for a given setup and production plan when the setup times follow a Gamma distribution. A sample average approximation procedure is applied to obtain upper bounds and a statistical lower bound. This is then used to benchmark the performance of two additional heuristics. A first heuristic is based on changing the capacity in the deterministic counterpart, while the second heuristic artificially modifies the setup time. We conduct our computational experiments on well-known problem instances and provide comprehensive analyses to evaluate the performance of each heuristic. (C) 2018 Elsevier B.V.

The two participants were high school mathematics teachers, who vary in their levels of experience. Two forms of data were collected to obtain more in-depth data about the transformations within among mathematical ideas: a questionnaire including 14 open-ended mathematical tasks and semi-structured interviews. Results indicated that individuals had different ways in constructing mathematical ideas and that their mathematical ideas were derived from the transition between meaning and formalism.conference-paper.listelement.badge A Comparative Analysis of Ruling Right-wing Populism towards Globalization in the Context of Refugee Crises: The Cases of Turkey and Hungary(2023) Saatçioğlu, BekenHow do governing, right-wing populist parties in and outside the EU approach globalization on the issue of international migration? This paper addresses this question by focusing on Hungary’s Fidesz and Turkey’s Justice and Development Party (AKP) in the context of the 2015 Syrian refugee crisis. It studies the discourses of these parties and their leaders regarding the liberal international order and the EU, and evaluates whether EU membership makes a difference in these arguments. This fills a gap in the literature because how ruling right-wing populism in middle-power states like Hungary and Turkey challenges the global system, and what kind of globalization or de-globalization it asks for in the light of migration issues remains to be scrutinized. The paper argues: (1) Fidesz and AKP are both “selective globalizers” that still challenge globalization and the EU within a populist foreign policy framework pitting “liberal, corrupt, global, EU elites” against the people (Christians for Fidesz, Syrian Muslim refugees for the AKP), (2) They differ because: (a) Fidesz’ challenges heavily focus on the EU while the AKP’s discourse extends to the global system and its institutions (the UN), (b) Fidesz’ EU contestation revolves around the need to protect “Hungarian sovereignty” and “Christian European culture” from “Brussels elites” while AKP’s rhetoric primarily reflects expectations of satisfactory “transactionalism” from the EU.Conference Object A Comparative Analysis of the Health Care Utilization and Costs of Patients Diagnosed With and Without Liver Cancer in the Us Medicare Population(2017) Ogbomo, A.; Lin, Y.; Keshishian, A; Xie, L; Yuce, H; Başer, Onur...Conference Object Article Citation - WoS: 3Citation - Scopus: 1A Configurational Analysis of the Impact of Entrepreneurial Orientation and Global Mindset on Export Performance of Smes(SAGE Publications Inc., 2024) Matemane, R.; Mintah, R.; Şahin, F.; Karadağ, H.Although contemporary literature provides several important insights into the role of attributes of SMEs, there is much less evidence on what configuration of entrepreneurial orientation and global mindset makes this process successful, that is, contributing to the export performance of SMEs. This study uses a fuzzy set qualitative comparative analysis on a sample of 97 SMEs in Ghana to explore the potential complementary role between the entrepreneurial orientation dimensions and global mindset for superior export performance. The results indicate two different yet equifinal configurations of these factors that lead to a high level of export performance of SMEs. One of the configurations shows that proactive and innovative SMEs with managers high on global mindset achieve superior export performance regardless of their willingness to take risks. Another configuration indicates that regardless of the global mindset of managers, SMEs can achieve higher export performance by being proactive, innovative, and willing to take high risks. Several implications for theory and practice are discussed based on the findings. © The Author(s) 2024.Article Citation - WoS: 5Citation - Scopus: 8A Data-Assisted Reliability Model for Carrier-Assisted Cold Data Storage Systems(Elsevier, 2020) Arslan, Şuayb Şefik; Göker, Turguy; Peng, JamesCold data storage systems are used to allow long term digital preservation for institutions’ archive. The common functionality among cold and warm/hot data storage is that the data is stored on some physical medium for read-back at a later time. However in cold storage, write and read operations are not necessarily done in the same exact geographical location. Hence, a third party assistance is typically utilized to bring together the medium and the drive. On the other hand, the reliability modeling of such a decomposed system poses few challenges that do not necessarily exist in other warm/hot storage alternatives such as fault detection and absence of the carrier, all totaling up to the data unavailability issues. In this paper, we propose a generalized non-homogenous Markov model that encompasses the aging of the carriers in order to address the requirements of today's cold data storage systems in which the data is encoded and spread across multiple nodes for the long-term data retention. We have derived useful lower/upper bounds on the overall system availability. Furthermore, the collected field data is used to estimate parameters of a Weibull distribution to accurately predict the lifetime of the carriers in an example scale-out setting.
