    Mutual Correlation of Nist Statistical Randomness Tests and Comparison of Their Sensitivities on Transformed Sequences
    (Tubitak Scientific & Technological Research Council Turkey, 2017) Doganaksoy, Ali; Sulak, Fatih; Uguz, Muhiddin; Seker, Okan; Akcengiz, Ziya
    Random sequences are widely used in many cryptographic applications and hence their generation is one of the main research areas in cryptography. Statistical randomness tests are introduced to detect the weaknesses or nonrandom characteristics that a sequence under consideration may have. In the literature, there exist various statistical randomness tests and test suites, defined as a collection of tests. An efficient test suite should consist of a number of uncorrelated statistical tests each of which measures randomness from another point of view. `Being uncorrelated' is not a well-defined or well-understood concept in the literature. In this work, we apply Pearson's correlation test to measure the correlation between the tests. In addition, we define five new methods for transforming a sequence. Our motivation is to detect those tests whose results are invariant under a certain transformation. To observe the correlation, we use two methods. One is the direct correlation between the tests and the other is the correlation between the results of a test on the sequence and its transformed form. In light of the observations, we conclude that some of the tests are correlated with each other. Furthermore, we conclude that in designing a reliable and efficient suite we can avoid overpopulating the list of test functions by employing transformations together with a reasonable number of statistical test functions.

    Exploring Emotional Intelligence at Work: a Review of Current Evidence
    (IGI Global, 2017) Orta,I.M.; Camgoz,S.M.
    Emotional intelligence is defined as the ability to perceive, understand, regulate, and use emotions. Organizational settings are now considered important arenas for the manifestation of human emotions. In order to establish long-term success, today’s organizations continually emphasize the search for emotionally intelligent employees. This chapter provides a detailed overview of the current literature on emotional intelligence with respect to work-related attitudes, behaviors, and outcomes. In particular, it provides empirical evidence for the associations of emotional intelligence with job satisfaction, work performance, organizational commitment, organizational citizenship behavior, effective leadership, and well-being. This chapter also provides practical implications and suggestions for future research by addressing plausible moderators and mediators, which are related to emotional intelligence. © 2018 by IGI Global.

    Spectral Approach To Derive the Representation Formulae for Solutions of the Wave Equation
    (Hindawi Publishing Corporation, 2012) Guseinov, Gusein Sh.
    Using spectral properties of the Laplace operator and some structural formula for rapidly decreasing functions of the Laplace operator, we offer a novel method to derive explicit formulae for solutions to the Cauchy problem for classical wave equation in arbitrary dimensions. Among them are the well-known d'Alembert, Poisson, and Kirchhoff representation formulae in low space dimensions.

    Legitimation, Co-Optation, and Survival: Why Is Turkey Silent on China’s Persecution of Uyghurs?
    (Routledge, 2023) Eliküçük Yıldırım,N.
    China built internment camps officially referred to as training centres within the scope of a policy for countering extremism and terrorism in the Xinjiang Uyghur Autonomous Region in 2017. While the repression imposed by China on Uyghurs in these camps has attracted the response of the international community, there has been neither a public protest nor a meaningful government response to China in Turkey, despite it having been the voice of Uyghurs on international platforms before 2017. This study aims to identify the reasons for Turkey's silence on the persecution of Uyghurs by utilizing the legitimation and co-optation strategies of the authoritarian stability framework. The Turkish government’s legitimation strategies of “rallying around the flag” via anti-Americanism and the economic expectations of China to boost its performance-based legitimacy are evaluated as reasons for the government’s silence on the Uyghur cause. Moreover, it is also discussed how formal and informal co-optation strategies of the government with nationalist and Eurasianist parties are playing a role as a bolstering mechanism of its silence policy on Uyghurs. © 2023 Informa UK Limited, trading as Taylor & Francis Group.

    Partner Phubbing and Sleep Quality: Serial Mediation Models With Relationship Satisfaction and Perceived Stress
    (Sage Publications inc, 2024) Dikdere, Busra; Turkarslan, Kutlu Kagan
    The increasing integration of technology into our lives has been affecting our daily routines and even our sleeps. Being a relatively new concept, phubbing refers to the act of overly engaging with one's phone while dismissing those around in the social settings. In this context, partner phubbing involves individuals exhibiting this neglect in the presence of their romantic partners. Evidence suggests that higher partner phubbing may lead to lower relationship satisfaction and higher perceived stress. The aim of the present cross-sectional study was to examine whether relationship satisfaction and perceived stress mediate the relationship between partner phubbing and sleep quality. Four hundred twenty-three individuals (females = 78.5%, M-age = 29.19, SD = 6.87) participated in the study and completed the measures of partner phubbing, relationship satisfaction, perceived stress, and sleep quality. The results of the serial mediation analyses showed that partner phubbing was not a direct predictor of sleep quality. However, the relationship between partner phubbing and sleep quality was mediated by the four indirect paths through relationship satisfaction (beta = 0.04, p < .05), perceived stress (beta = 0.09, p < .05), relationship satisfaction-perceived stress (beta = 0.02, p < .05), and perceived stress-relationship satisfaction (beta = 0.00, p < .05). The findings suggest that partner phubbing may diminish sleep quality by reducing relationship satisfaction and increasing perceived stress levels. Alternatively, perceived stress exacerbated by partner phubbing could reduce relationship satisfaction, which eventually worsens sleep quality. Digital detox programs, group interventions, emotion-focused couple interventions, and stress management training can help overcome the effects of partner phubbing on sleep quality.

    A Neural Network-Based Approach for Calculating Dissolved Oxygen Profiles in Reservoirs
    (Springer London Ltd, 2003) Soyupak, S; Karaer, F; Gürbüz, H; Kivrak, E; Sentürk, E; Yazici, A
    A Neural Network (NN) modelling approach has been shown to be successful in calculating pseudo steady state time and space dependent Dissolved Oxygen (DO) concentrations in three separate reservoirs with different characteristics using limited number of input variables. The Levenberg-Marquardt algorithm was adopted during training. Pre-processing before training and post processing after simulation steps were the treatments applied to raw data and predictions respectively. Generalisation was improved and over-fitting problems were eliminated: Early stopping method was applied for improving generalisation. The correlation coefficients between neural network estimates and field measurements were as high as 0.98 for two of the reservoirs with experiments that involve double layer neural network structure with 30 neurons within each hidden layer. A simple one layer neural network structure with 11 neurons has yielded comparable and satisfactorily high correlation coefficients for complete data set, and training, validation and test sets of the third reservoir.

    Trapping Centers and Their Distribution in Tl2ga2< Layered Single Crystals
    (Pergamon-elsevier Science Ltd, 2009) Isik, M.; Gasanly, N. M.
    Thermally stimulated current (TSC) measurements with current flowing perpendicular to the layers were carried out on Tl2Ga2Se3S layered single crystals in the temperature range of 10-260K. The experimental data were analyzed by using different methods, such as curve fitting, initial rise and isothermal decay methods. The analysis revealed that there were three trapping centers with activation energies of 12, 76 and 177 meV. It was concluded that retrapping in these centers was negligible, which was confirmed by the good agreement between the experimental results and the theoretical predictions of the model that assumes slow retrapping. The capture cross section and the concentration of the traps have been also determined. An exponential distribution of electron traps was revealed from the analysis of the TSC data obtained at different light illumination temperatures. This experimental technique provided values of 10 and 88 meV/decade for the traps distribution related to two different trapping centers. (C) 2009 Elsevier Ltd. All rights reserved.

    Mixture Representations for Three-State Systems With Three-State Components
    (Ieee-inst Electrical Electronics Engineers inc, 2015) Eryilmaz, Serkan
    This paper is concerned with dynamic reliability modeling of three-state systems consisting of three-state s-independent components. The components and the systems are assumed to be in three states: perfect functioning, partial performance, and complete failure. Survival functions of such systems are studied in different state subsets. It is shown that the survival function of a three-state system with a general structure can be represented as a mixture of the survival functions of the three-state k-out-of-n:G systems. The results are illustrated for the three-state consecutive-k-out-of-n:G systems whose components degrade according to a Markov process.

    Increasing Creativity With Unusual Designs
    (Elsevier Science Bv, 2012) Ergin, Merve Hande; Rouyendegh (Babek Erdebilli), Babak Daneshvar
    Creativity is important in synthesizing new ideas. For the engineering students, there are different methods to increase the level of creativity. Also, the unusual designs stimulate the students' creativity helping them to think innovatively. The assessment tool CEDA (Creative Engineering Design Assessment) is applied with minor modifications (CEDA-modified) to measure creativity in IE 101 Introduction to Engineering course. The CEDA score is modified by using AHP method to decrease the subjectivity of the assessment criteria. The study is applied to 49 industrial engineering students as an exam question. The question asked requires developing five advantages to an unusual design given. Male students developed more ideas compared to female students when they face with unusual design. More designs may be required to discuss through out the term and a proper term project that requires more design may be submitted to increase the success level.
