To obtain a small amount of energy, an exhaust system which is suitable for recovery waste heat has been constructed. Totally 27 TEGs have been used to convert from the heat to electric energy. By producing a small amount of this energy by the help of thermoelectric generators can reduce engine loads thus decreasing pollutant emissions, fuel consumption, and CO2. This case study is conducted in an effort to better understand and improve the performance of thermoelectric heat recovery systems for automotive use. As a result of this study, 0,45 A averaged current rate, 13,02 V averaged voltage rate and 5,8 W averaged electrical energy have been produced in a five hours operation time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermoelectric" title="thermoelectric">thermoelectric</a>, <a href="https://publications.waset.org/abstracts/search?q=peltier" title=" peltier"> peltier</a>, <a href="https://publications.waset.org/abstracts/search?q=thermoelectric%20generator%20%28TEG%29" title=" thermoelectric generator (TEG)"> thermoelectric generator (TEG)</a>, <a href="https://publications.waset.org/abstracts/search?q=exhaust" title=" exhaust"> exhaust</a>, <a href="https://publications.waset.org/abstracts/search?q=cogeneration" title=" cogeneration"> cogeneration</a> </p> <a href="https://publications.waset.org/abstracts/29471/experimental-analysis-of-electrical-energy-producing-using-the-waste-heat-of-exhaust-gas-by-the-help-of-thermoelectric-generator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29471.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">653</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">74</span> Evaluation of Manual and Automatic Calibration Methods for Digital Tachographs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarp%20Erturk">Sarp Erturk</a>, <a href="https://publications.waset.org/abstracts/search?q=Levent%20Eyigel"> Levent Eyigel</a>, <a href="https://publications.waset.org/abstracts/search?q=Cihat%20Celik"> Cihat Celik</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammet%20Sahinoglu"> Muhammet Sahinoglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Serdar%20Ay"> Serdar Ay</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasin%20Kaya"> Yasin Kaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Kaya"> Hasan Kaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a quantitative analysis on the need for automotive calibration methods for digital tachographs. Digital tachographs are mandatory for vehicles used in people and goods transport and they are an important aspect for road safety and inspection. Digital tachographs need to be calibrated for workshops in order for the digital tachograph to display and record speed and odometer values correctly. Calibration of digital tachographs can be performed either manual or automatic. It is shown in this paper that manual calibration of digital tachographs is prone to errors and there can be differences between manual and automatic calibration parameters. Therefore automatic calibration methods are imperative for digital tachograph calibration. The presented experimental results and error analysis clearly support the claims of the paper by evaluating and statistically comparing manual and automatic calibration methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20tachograph" title="digital tachograph">digital tachograph</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20safety" title=" road safety"> road safety</a>, <a href="https://publications.waset.org/abstracts/search?q=tachograph%20calibration" title=" tachograph calibration"> tachograph calibration</a>, <a href="https://publications.waset.org/abstracts/search?q=tachograph%20workshops" title=" tachograph workshops"> tachograph workshops</a> </p> <a href="https://publications.waset.org/abstracts/82352/evaluation-of-manual-and-automatic-calibration-methods-for-digital-tachographs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82352.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">333</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">73</span> Human Smuggling and Turkey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Perihan%20Hazel%20Kaya">Perihan Hazel Kaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20G%C3%B6ktu%C4%9F%20Kaya"> Mustafa Göktuğ Kaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Turkey has been a busy destination for immigration and it will always be as it is the geographical and cultural exit door of the East and the entrance door of the West. Among these immigrations, we can see the victims of human trafficking, human smuggling, refugees and those who came here to work and live. Human smuggling, which is one of the movements of illegal immigration, is the specific subject of this work. The fact that our country lies on the transportation destinations between the continents of Asia, Europe and Africa, the crime of human smuggling is highly committed in our country. The aim of the victims of human smuggling is to go to a more developed country to have higher standards of living, to get a better job and to escape from the economic and social instability of their countries. The human smuggling, which has gathered pace due to the improvements in communication and transportation, is not a regional issue and has become one of the most important problems for almost all countries. Accordingly, the reasons, methods and extent of human smuggling will be dealt firstly. Later, it will be studied why Turkey is preffered in human smuggling. Finally, statistical data will be given to show how much human smuggling has gone far in Turkey and the study will be finished with that what is being done and what can be done to prevent it. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20smuggling" title="human smuggling">human smuggling</a>, <a href="https://publications.waset.org/abstracts/search?q=immigration" title=" immigration"> immigration</a>, <a href="https://publications.waset.org/abstracts/search?q=immigrator" title=" immigrator"> immigrator</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20trafficking" title=" human trafficking"> human trafficking</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkey" title=" Turkey"> Turkey</a> </p> <a href="https://publications.waset.org/abstracts/29407/human-smuggling-and-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29407.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">406</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">72</span> Eight-Week Exercise for Women: Impact on Anomalies in Width Depth and Environmental Dimension</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yalcin%20Kaya">Yalcin Kaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Arslan"> Fatma Arslan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20Selim%20Kaya"> Ahmet Selim Kaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aimed to determine the undesirable hypertrophic anomalies in the body of females and to investigate how they can be affected by the exercise program according to the applied 8 week individual conditions. The research was carried out on 35 women who did not have any regular previous sports practice and had an approximate age of 30 ± 5.0 at the gymnasium because of their asymmetric structure and weight gain of the body. Measurements of width, depth, and periphery were taken from the participants' body, and the exercise protocol was applied for 8 weeks according to the individual measurements in accordance with the obtained measurements. After 8 weeks, the same measurements were applied again. Measurements were made by using ruler and paper tape. The findings were evaluated and differences were analyzed by paired sample t test. According to the findings obtained, ulnae distal proiecturas width averages were 44.77 ± 3.65 and 43.52 ± 3.47 pre- and post-exercise respectively. Bithorachanteric width averages were 29.3 ± 3.12 before exercise and 26.67 ± 3.27 after exercise. Average abdominal widths were observed as 18.64 ± 4.14 (before exercise) and 18.01 ± 6.27 (after exercise). The distances between the malleolus were measured as 16.98 ± 1.62 (before exercise) and 16.70 ± 1.64 (after exercise). The results were statistically significant (p < 0.05). The mean of pre-exercise Externus abdominis circumference was 93.97 ± 8.91, and the mean of post-exercise mean was 90.82 ± 8.24. The results are statistically significant (p < 0.05). In conclusion, findings of the study show that inactivity, daily uncontrolled activities or erroneous postural postures, malnutrition cause some anomalies in the human body. However, with consciously standardized and regular exercises, these abnormalities are reduced by an eight-week exercise protocol in parallel with the expulsion of excess kilos and can be removed when working much longer and fitter, it is proposed to be healthier and more beautiful in appearance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=women" title="women">women</a>, <a href="https://publications.waset.org/abstracts/search?q=body" title=" body"> body</a>, <a href="https://publications.waset.org/abstracts/search?q=circumference-width%20and%20depth%20measurements" title=" circumference-width and depth measurements"> circumference-width and depth measurements</a>, <a href="https://publications.waset.org/abstracts/search?q=hypertrophy" title=" hypertrophy"> hypertrophy</a>, <a href="https://publications.waset.org/abstracts/search?q=exercise" title=" exercise"> exercise</a> </p> <a href="https://publications.waset.org/abstracts/79027/eight-week-exercise-for-women-impact-on-anomalies-in-width-depth-and-environmental-dimension" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79027.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">384</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">71</span> Structural Breaks, Asymmetric Effects and Long Memory in the Volatility of Turkey Stock Market </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Serpil%20T%C3%BCrky%C4%B1lmaz">Serpil Türkyılmaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Mesut%20Bal%C4%B1bey"> Mesut Balıbey</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, long memory properties in volatility of Turkey Stock Market are being examined through the FIGARCH, FIEGARCH and FIAPARCH models under different distribution assumptions as normal and skewed student-t distributions.

A total of 68 students with a mean age of 10.01±0.12 were included in the study, 58 of them with standard development, 9 partially visually impaired and 1 totally visually disabled student. The student with a total visual impairment could not participate in the reading speed test due to her total visual impairment. The following data were measured in the participant students before the project; Reading speed measurement in 1 minute, Reading comprehension questions, Burdon attention test, 50 questions of math quiz timed with a stopwatch. Participants were trained for 3 weeks, 5 days a week, for a total of two hours a day. In this study, right-brain developing exercises were carried out with the use of an abacus, and it was aimed to develop both mathematical and attention of students with questions prepared with numerical data taken from fairy tale activities. Among these problems, the study was supported with multiple-choice, 5W (what, where, who, why, when?), 1H (how?) questions along with true-false and fill-in-the-blank activities. By using memory cards, students' short-term memories were strengthened, photographic memory studies were conducted and their visual intelligence was supported. Auditory intelligence was supported by aiming to make calculations by using the abacus in the minds of the students with the numbers given aurally. When calculating the numbers by touching the real abacus, the development of students' tactile intelligence is enhanced. Research findings were analyzed in SPSS program, Kolmogorov Smirnov test was used for normality analysis. Since the variables did not show normal distribution, Wilcoxon test, one of the non-parametric tests, was used to compare the dependent groups. Statistical significance level was accepted as 0.05. The reading speed of the participants was 83.54±33.03 in the pre-test and 116.25±38.49 in the post-test. Narration pre-test 69.71±25.04 post-test 97.06±6.70; BURDON pretest 84.46±14.35 posttest 95.75±5.67; rapid math processing skills pretest 90.65±10.93, posttest 98.18±2.63 (P<0.05). It was determined that the pre-test and post-test averages of students with typical development and students with low vision were also significant for all four values (p<0.05). As a result of the data obtained from the participants, it is seen that the study was effective in terms of measurement parameters, and the findings were statistically significant. Therefore, it is recommended to use the method widely. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abacus" title="Abacus">Abacus</a>, <a href="https://publications.waset.org/abstracts/search?q=reading%20speed" title=" reading speed"> reading speed</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20intelligences" title=" multiple intelligences"> multiple intelligences</a>, <a href="https://publications.waset.org/abstracts/search?q=right%20brain%20training" title=" right brain training"> right brain training</a>, <a href="https://publications.waset.org/abstracts/search?q=visually%20impaired" title=" visually impaired"> visually impaired</a> </p> <a href="https://publications.waset.org/abstracts/146310/investigation-of-the-effects-of-visually-disabled-and-typical-development-students-on-their-multiple-intelligence-by-applying-abacus-and-right-brain-training" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146310.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">182</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">68</span> Supercritical Methanol for Biodiesel Production from Jatropha Oil in the Presence of Heterogeneous Catalysts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Velid%20Demir">Velid Demir</a>, <a href="https://publications.waset.org/abstracts/search?q=Mesut%20Akg%C3%BCn"> Mesut Akgün</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The lanthanum and zinc oxide were synthesized and then loaded with 6 wt% over γ-Al₂O₃ using the wet impregnation method.

The large amount of customer data owned by the service providers is suitable for analysis by machine learning methods. In this study, expenditure data of customers are analyzed by using an artificial neural network (ANN). The ANN model is applied to the data of customers with different billing duration. The proposed model successfully predicts the churn probabilities at 83% accuracy for only three months expenditure data and the prediction accuracy increases up to 89% when the nine month data is used. The experiments also show that the accuracy of ANN model increases on an extended feature set with information of the changes on the bill amounts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=customer%20relationship%20management" title="customer relationship management">customer relationship management</a>, <a href="https://publications.waset.org/abstracts/search?q=churn%09prediction" title=" churn prediction"> churn prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=telecom%20industry" title=" telecom industry"> telecom industry</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title=" deep learning"> deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20networks" title=" artificial neural networks"> artificial neural networks</a> </p> <a href="https://publications.waset.org/abstracts/126999/churn-prediction-for-telecommunication-industry-using-artificial-neural-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126999.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">145</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">66</span> The Effect of Dopamine D2 Receptor TAQ A1 Allele on Sprinter and Endurance Athlete </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C3%96znur%20%C3%96zge%20%C3%96zcan">Öznur Özge Özcan</a>, <a href="https://publications.waset.org/abstracts/search?q=Canan%20Sercan"> Canan Sercan</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamza%20Kulaks%C4%B1z"> Hamza Kulaksız</a>, <a href="https://publications.waset.org/abstracts/search?q=Mesut%20Karahan"> Mesut Karahan</a>, <a href="https://publications.waset.org/abstracts/search?q=Korkut%20Ulucan"> Korkut Ulucan </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Genetic structure is very important to understand the brain dopamine system which is related to athletic performance.

In the present study, we intended to investigate the Receptor-2 Gene (<em>DRD2</em>) rs1800497, which is related to brain dopaminergic system. 10 sprinter and 10 endurance athletes were enrolled in the study. Real-Time Polymerase Chain Reaction method was used for genotyping. According to results, A1A1, A1A2 and A2A2 genotypes in athletes were 0 (%0), 3 (%15) and 17 (%85). A1A1 genotype was not found and A2 allele was counted as the dominating allele in our cohort.

Smart cities connect the various components of the city through the main and sub-networks in addition to a set of applications and thus be able to collect data that is the basis for providing technological solutions to manage resources and provide services. The basis of the work of the smart city is the use of artificial intelligence and the technology of the Internet of Things. The work presents the concept of smart cities, the pillars, standards, and evaluation indicators on which smart cities depend, and the reasons that prompted the world to move towards its establishment. It also provides a simplified hypothetical way to measure the ideal smart city model by defining some indicators and key pillars, simulating them with logic circuits, and testing them to determine if the city can be considered an ideal smart city or not. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=factors" title="factors">factors</a>, <a href="https://publications.waset.org/abstracts/search?q=indicators" title=" indicators"> indicators</a>, <a href="https://publications.waset.org/abstracts/search?q=logic%20gates" title=" logic gates"> logic gates</a>, <a href="https://publications.waset.org/abstracts/search?q=pillars" title=" pillars"> pillars</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20city" title=" smart city"> smart city</a> </p> <a href="https://publications.waset.org/abstracts/150374/key-performance-indicators-and-the-model-for-achieving-digital-inclusion-for-smart-cities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150374.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">150</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">63</span> Quantum Mechanism Approach for Non-Ruin Probability and Comparison of Path Integral Method and Stochastic Simulations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20Kaya">Ahmet Kaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Quantum mechanism is one of the most important approaches to calculating non-ruin probability.

Engle and Granger’s least squares method and Johansen’s conditional maximum likelihood method are the most widely-used methods to determine the relationships among variables. Furthermore, a method proposed to test a unit root based on the periodogram ordinates has certain advantages over conventional tests. Periodograms can be calculated without any model specification and the exact distribution under the assumption of a unit root is obtained. For higher order processes the distribution remains the same asymptotically. In this study, in order to indicate advantages over conventional test of periodograms, we are going to examine a possible relationship between tourism and economic growth during the period 1999:01-2010:12 for Turkey by using periodogram method, Johansen’s conditional maximum likelihood method, Engle and Granger’s ordinary least square method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cointegration" title="cointegration">cointegration</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20growth" title=" economic growth"> economic growth</a>, <a href="https://publications.waset.org/abstracts/search?q=periodogram%20ordinate" title=" periodogram ordinate"> periodogram ordinate</a>, <a href="https://publications.waset.org/abstracts/search?q=tourism" title=" tourism"> tourism</a> </p> <a href="https://publications.waset.org/abstracts/14439/a-periodogram-based-spectral-method-approach-the-relationship-between-tourism-and-economic-growth-in-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14439.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">269</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">58</span> A Comprehensive Study on the Porosity Effect of Ti-20Zr Alloy Produced by Powder Metallurgy as a Biomaterial</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eyyup%20Murat%20Karakurt">Eyyup Murat Karakurt</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan%20Huang"> Yan Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Kaya"> Mehmet Kaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Huseyin%20Demirtas"> Huseyin Demirtas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the effect of the porosity effect of Ti-20Zr alloy produced by powder metallurgy as a biomaterial was investigated experimentally.

Dink had been voicing the atrocities against the Armenians between 1915 and 1922 during the Ottoman rule, and his comments on the issue appeared in the Turkish media many times before his assassination. Despite intensive media coverage of his assassination, there is not enough research analyzing how national and international media presented Dink’s assassination. In this research, a content analysis of national and international news articles (N= 139) is conducted to identify whether there is a significant difference in national and international media’s coverage of the assassination. The content of the newspaper articles is categorized and coded according to the topics covered. The findings of this research suggested that Dink’s assassination wounded Turkey’s image as a democratic country. It has also been found that the Turkish media focused on security forces and their responsibility in Dink’s assassination, whereas international media focused more on the Article 301 of the Turkish penal code, freedom of expression, and atrocities against the Armenians during the Ottoman rule. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hrant%20Dink" title="Hrant Dink">Hrant Dink</a>, <a href="https://publications.waset.org/abstracts/search?q=Armenian" title=" Armenian"> Armenian</a>, <a href="https://publications.waset.org/abstracts/search?q=journalist" title=" journalist"> journalist</a>, <a href="https://publications.waset.org/abstracts/search?q=assassination" title=" assassination "> assassination </a> </p> <a href="https://publications.waset.org/abstracts/93285/media-coverage-of-the-turkish-armenian-journalist-hrant-dink-assassination-the-analysis-of-media-news-in-the-aftermath-of-the-assassination" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93285.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">56</span> Influence of the Growth Rate on Eutectic Microstructures and Physical Properties of Aluminum–Silicon-Cobalt Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aynur%20Aker">Aynur Aker</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Kaya"> Hasan Kaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Al-12.6wt.%Si-%2wt.Co alloy was prepared in a graphite crucible under vacuum atmosphere.

Therefore, teachers need to find new ways to appeal to the needs and interests of their students and meet the demands of the 21st century at the same time. One way to do so in English language learning has been to incorporate various technology tools into classroom practices. Although teachers think these practices are effective and their students enjoy them, students may have different perceptions. To find out what students think about the use of technology tools in terms of developing 21st-century skills and knowledge, this study was conducted at Anadolu University School of Foreign Languages. A questionnaire was administered to 40 students at elementary level. Afterward, semi-structured interviews were held with 8 students to provide deeper insight into their perceptions.

We aimed to investigate the efficacy of quercetin on oxidant and antioxidant parameters of infectious pancreatic necrosis virus, which is important for fish farming and economy in vitro. Quercetin experimental model was used in the cell culture of Oncorhynchus mykiss infected with infectious pancreatic necrosis virus. Malondialdehyde, ceruloplasmin, total oxidant capacity, total antioxidant levels, and glutathione-peroxidase were measured in the samples. As a result of the study, it was observed that quercetin can minimize the damage caused by scavenging free radicals in cells infected with infectious pancreatic necrosis virus. Thus, we think that an important development can be achieved for fish farming and the economy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=IPNV" title="IPNV">IPNV</a>, <a href="https://publications.waset.org/abstracts/search?q=oncorhynchus%20mykiss" title=" oncorhynchus mykiss"> oncorhynchus mykiss</a>, <a href="https://publications.waset.org/abstracts/search?q=TAS" title=" TAS"> TAS</a>, <a href="https://publications.waset.org/abstracts/search?q=TOS" title=" TOS"> TOS</a>, <a href="https://publications.waset.org/abstracts/search?q=quercetin" title=" quercetin"> quercetin</a> </p> <a href="https://publications.waset.org/abstracts/176688/investigation-of-the-effects-of-quercetin-on-oxidative-stress-in-cells-infected-with-infectious-pancreatic-necrosis-virus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176688.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">65</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">51</span> Microstructural Characterization and Mechanical Properties of Al-2Mn-5Fe Ternary Eutectic Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emin%20%C3%87adirli">Emin Çadirli</a>, <a href="https://publications.waset.org/abstracts/search?q=Izzettin%20Yilmazer"> Izzettin Yilmazer</a>, <a href="https://publications.waset.org/abstracts/search?q=U%C4%9Fur%20B%C3%BCy%C3%BCk"> Uğur Büyük</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Kaya"> Hasan Kaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Al-2Mn-5Fe eutectic alloy (wt.%) was prepared in a graphite crucible under vacuum atmosphere.

The experiments are conducted to cover transition zone for the Reynolds numbers ranging from 100 to 4800 by fused silica and stainless steel microtubes having diameters of 103-180 µm. The applicability of the Logarithmic Mean Temperature Difference (LMTD) method is revealed and an experimental method is developed to calculate the heat transfer coefficient. Heat transfer is supplied by a water jacket surrounding the microtubes and heat transfer coefficients are obtained by LMTD method. The results are compared with data obtained by the correlations available in the literature in the study. The experimental results indicate that the Nusselt numbers of microtube flows do not accord with the conventional results when the Reynolds number is lower than 1000. After that, the Nusselt number approaches the conventional theory prediction. Moreover, the scaling effects in micro scale such as axial conduction, viscous heating and entrance effects are discussed. On the aspect of fluid characteristics, the friction factor is well predicted with conventional theory and the conventional friction prediction is valid for water flow through microtube with a relative surface roughness less than about 4 %. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microtube" title="microtube">microtube</a>, <a href="https://publications.waset.org/abstracts/search?q=laminar%20flow" title=" laminar flow"> laminar flow</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20factor" title=" friction factor"> friction factor</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer" title=" heat transfer"> heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=LMTD%20method" title=" LMTD method"> LMTD method</a> </p> <a href="https://publications.waset.org/abstracts/34123/an-experimental-study-on-heat-and-flow-characteristics-of-water-flow-in-microtube" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34123.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">460</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">49</span> Understanding the Motivations behind the Assassination of Turkish Armenian Journalist, Hrant Dink</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nusret%20Mesut%20Sahin">Nusret Mesut Sahin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hrant Dink, a prominent Turkish-Armenian journalist, and editor-in-chief of the bilingual Turkish-Armenian newspaper Agos was assassinated in Istanbul on January 19th, 2007 by a nationalist extremist, Ogun Samast. Dink had been voicing the atrocities against the Armenians between 1915 and 1922 during the Ottoman rule, and his comments on the issue appeared in the Turkish media many times before his assassination. It has been argued that the suffocating atmosphere created by the Turkish news media targeting Mr. Dink made him a target of an extremist Turkish juvenile. This study analyzes the media news to understand and explain why Hrant Dink became the target of a nationalist extremist. In this research, content analysis of news articles (N= 170) is conducted to identify whether there is a link between hate speech against Hrant Dink in the Turkish media and his assassination. The content of the newspaper articles is categorized and coded according to the hate language being used. The analysis suggested that Turkish media paved the way for Dink’s assassination. Hate speech against Hrant Dink on the media had risen gradually before the assassination. The study also found that the number of news stories covering hate speech and racist discourse against non-Muslim citizens of Turkey also increased dramatically before the assassination. Therefore, hate speech against minorities in media narratives and news reports should be monitored, and political figures or leaders of social groups who are targeted by some media outlets should be protected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hrant%20Dink" title="Hrant Dink">Hrant Dink</a>, <a href="https://publications.waset.org/abstracts/search?q=assassination" title=" assassination"> assassination</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkish%20Armenian%20journalist" title=" Turkish Armenian journalist"> Turkish Armenian journalist</a>, <a href="https://publications.waset.org/abstracts/search?q=media" title=" media"> media</a> </p> <a href="https://publications.waset.org/abstracts/91256/understanding-the-motivations-behind-the-assassination-of-turkish-armenian-journalist-hrant-dink" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91256.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">159</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">48</span> Effect of Lead Content on Physical Properties of the Al–Si Eutectic Alloys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Kaya">Hasan Kaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Effect of lead content on the microstructure, mechanical (microhardness, ultimate tensile strength) and electrical resistivity properties of Al–Si eutectic alloys has been investigated. Al–12.6 Si–xSn (x=1, 2, 4, 6 and 8 wt. %) were prepared using metals of 99.99% high purity in the vacuum atmosphere. These alloys were directionally solidified under constant temperature gradient (5.50 K/mm) and growth rate (8.25 μm/s) by using a Bridgman–type directional solidification furnace. Eutectic spacing, microhardness, ultimate tensile strength and electrical resistivity were expressed as functions of the composition by using a linear regression analysis. The dependency of the eutectic spacing, microhardness, tensile strength and electrical resistivity on the composition (Sn content) were determined. According to experimental results, the microhardness, ultimate tensile strength and electrical resistivity of the solidified samples increase with increasing the Sn content, but decrease eutectic spacing. Variation of electrical resistivity with the temperature in the range of 300-500 K for studied alloys was also measured by using a standard d.c. four-point probe technique. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=content%20elements" title="content elements">content elements</a>, <a href="https://publications.waset.org/abstracts/search?q=solidification" title=" solidification"> solidification</a>, <a href="https://publications.waset.org/abstracts/search?q=microhardness" title=" microhardness"> microhardness</a>, <a href="https://publications.waset.org/abstracts/search?q=strength" title=" strength"> strength</a> </p> <a href="https://publications.waset.org/abstracts/45734/effect-of-lead-content-on-physical-properties-of-the-al-si-eutectic-alloys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45734.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">297</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">47</span> Dynamic Store Procedures in Database</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammet%20Dursun%20Kaya">Muhammet Dursun Kaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Asil"> Hasan Asil</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, different methods have been proposed to optimize question processing in database.

This research creates dynamic store procedures in the database according to the proposed algorithm. This method has been tested on applied software and results shows a significant improvement in reducing the query processing time and also reducing the workload of DBMS.

There are two methods have been used; frequency domain (Digital Wavelet Transform-DWT, Digital Cosine Transform-DCT, and Digital Fourier Transform-DFT) and spatial domain (Least Significant Bits-LSB) domain. Experimental results show that embedding in frequency domains resist against one type of attacks, and embedding in spatial domain is resist against another group of attacks. Peak Signal Noise Ratio (PSNR) and Similarity Ratio (SR) values are two measurement values for testing. These two values give very promising result for information hiding in medical MR images. <p class="card-text"><strong>Keywords:</strong> <a
