The existence and uniqueness of a solution of the inverse problem under considerations are established. Some results on the numerical solution with an example are presented.Article Citation - WoS: 26Citation - Scopus: 38An Integrative Approach To Relationship Marketing, Customer Value, and Customer Outcomes in the Retail Banking Industry: a Customer-Based Perspective From Turkey(Routledge Journals, Taylor & Francis Ltd, 2019) Sayil, Emine Mediha; Akyol, Ayse; Simsek, Gulhayat Golbasi; Golbasi Simsek, GulhayatGiven how important it is to provide superior value to customers and to maintain customer loyalty for a sustainable competitive advantage, the aim of this paper is to examine the relationships among relationship marketing components of - trust, competency, commitment, communication, and conflict handling, - relationship investment, relationship quality, perceived customer value, satisfaction and loyalty in an integrated framework in the Turkish retail banking industry. Unlike previous studies, this research extends the literature by analysing affective as well as cognitive dimensions in the same model with a holistic view by simultaneously examining the direct and indirect effects of the related concepts. The distinctive nature of this study is its evaluation of customer satisfaction and loyalty from the perspective of actual consumers. The research model was tested using data collected from 685 retail banking customers by applying structural equation modelling. The findings show that relationship marketing induces loyalty through relationship quality, customer value, and satisfaction, which are mainly provided by trust, communication, and relationship investment. Furthermore, relationship investment and relationship quality are the most important factors in the development of customer value, satisfaction, and loyalty. The emotional value dimension, which captures the affective aspects of perceived value, has the strongest effect on both satisfaction and loyalty.Article Citation - WoS: 5Citation - Scopus: 6Skeletal Muscle Fatigue Does Not Affect Shooting Accuracy of Handball Players(Ios Press, 2019) Akyuz, Beyza; Avsar, Pinar Arpinar; Bilge, Murat; Deliceoglu, Gokhan; Korkusuz, FezaBACKGROUND: Shooting accuracy and ball speed are important factors relating to scoring in handball that could be affected by skeletal muscle fatigue. OBJECTIVE: To explore the effects of muscle fatigue on male handball players' shooting accuracy and ball speed. METHODS: Sixteen elite handball players (M-age = 17.1 +/- 1.7 years) participated in the laboratory and the field-testing sessions. Running speeds equal to 75% of participants' maximal oxygen uptake (VO2max) values from laboratory tests were used as the initial velocity for the 30-15 intermittent fitness test (30-15(IFT)) in the fatigue protocol. Participants shot to the target at random visual signals placed behind the target before and after fatigue. In order to measure wrist acceleration and ball speed, an accelerometer and a radar gun are used respectively and numbers of accurate and inaccurate shots also recorded. RESULTS: There were no significant differences between pre-fatigue and post-fatigue protocols in terms of accurate and inaccurate shots, and ball speed. Only wrist acceleration in the Y axis (M-pre(-fatigue) = 33.12, SD = 1.17msec; M-post - fatigue = 34.50, SD = 1.21msec) was affected by the fatigue protocol in inaccurate shots (p = 0.042). CONCLUSIONS: Muscular fatigue does not affect shooting accuracy and ball speed in male handball players.Conference Object Citation - WoS: 1Citation - Scopus: 4Fpga Based Dco-Ofdm Phy Transceiver for Vlc Systems(Institute of Electrical and Electronics Engineers Inc., 2019) Levent, V.E.; Uysal, M.; Saglam, G.; Ugurdag, H.F.; Fajar Rizqi Annafianto, N.; Aydin, F.; Kebapci, B.; Tesfay, Shewit Weldu; Annafianto, Nur Fajar RizqiSatisfying the demand for high bandwidth and low latency in Visible Light Communication (VLC) systems is a difficult challenge. VLC channels exhibit frequency-selectiveness at peak-speeds. This phenomenon generates a serious inter-symbol interference effect. A physical layer (PHY) design that can carry out physical layer communication tasks to overcome all these strains is required. In this study, an FPGA based PHY design that implements DCO-OFDM algorithm is described for VLC systems. A demo was performed with the developed PHY design using an LED transmitter and a photodetector receiver. © 2019 Chamber of Turkish Electrical Engineers.Conference Object Parametric Trigger Signal Generation With Microcontroller and Fpga Based Architectures(Ieee, 2019) Kazma, Coskun; Levent, Vecdi Emre; Aydin, NizamettinA new system to obtain information from the central nervous system has been developed. Our system consists of two main components. The first of these components is the machine, which is located on the index and middle finger tips, stimulating mechanoreceptors according to the test protocol. The other is a personal computer running a desktop software for the implementation of test protocols. The flow is as follows. The subjects are asked the question of the test protocol through the personal computer. The parameters are then transmitted to the embedded system board on the machine. The embedded system board takes step motors to apply the relevant test parameters. The desktop software expects the subject to answer the question using the right and/or the left mouse button of the computer mouse. After answering the relevant question, the test proceeds to the next step. According to the test protocol, the stimulation process of the mechanoreceptors located at the index and middle finger tips must start and terminate at the same time. From this perspective, the embedded system board with 3 18F46K22 PIC microcontrollers produces 2 square wave signals with different frequencies and amplitudes simultaneously. The embedded system card developed with the PIC microcontroller is also implemented on an FPGA. The system has also been tested on 24 blue- and white-collar employees and a significant result has been obtained.Conference Object Citation - WoS: 1Citation - Scopus: 1Design and Development of a New Tactile Stimulator(Ieee, 2019) Kazma, Coskun; Levent, Vecdi Emre; Aydin, NizamettinWe have designed and implement a tactile stimulator to obtain information from the central nervous system.

The purposes of this study were to: a) determine the acute effect of kinesio tape (KT) application on the ankle joint on balance performance, b) investigate the effects of an 8-week proprioceptive-neuromuscular (PN) training program on balance performance, and c) compare their effects vs modern dance technique classes alone. Thirty-three trained, university-level modern dance students (9 male, 24 female) were divided randomly into three groups: kinesio tape (KT, n=11), proprioceptive-neuromuscular (PN, n=11), or control (n=11). Static (turn-out passe-opened eyes/releve and turn-out passe-closed eyes/flat foot), semi-dynamic (airplane), and dynamic balance (monopodalic-straight and -transverse in a turn-out passe-eyes opened/flat foot) tests were performed before and after the intervention. One day after pre-tests, KT mechanical correction technique was applied to the left ankle joint (supporting leg) in the KT group, and tests were repeated to determine the acute effect of KT. The PN group participated in an 8-week balance training program (2 days/wk, 60 min/day) involving exercises using stable and unstable surfaces. Significant improvements were observed for all static and dynamic balance tests in the PN group; semi-dynamic airplane and dynamic monopodalic-straight and transverse tests improved in the KT group; and only semi-dynamic airplane test scores changed significantly for the control group (p<0.05). Our findings suggest that with the exception of the semi-dynamic airplane test, both PN training and KT application were more effective at improving balance performance for modern dancers than modern dance technique classes alone.
