small manufactured unmanned helicopter is tried to be increased. For this purpose, a small unmanned helicopter is manufactured in Erciyes University, Faculty of Aeronautics and Astronautics. It is called as ZANKA-Heli-I. For performance maximization, autopilot parameters are determined via minimizing a cost function consisting of flight performance parameters such as settling time, rise time, overshoot during trajectory tracking. For this purpose, a stochastic optimization method named as simultaneous perturbation stochastic approximation is benefited. Using this approach, considerable autonomous performance increase (around %23) is obtained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=small%20helicopters" title="small helicopters">small helicopters</a>, <a href="https://publications.waset.org/abstracts/search?q=hierarchical%20control" title=" hierarchical control"> hierarchical control</a>, <a href="https://publications.waset.org/abstracts/search?q=stochastic%20optimization" title=" stochastic optimization"> stochastic optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=autonomous%20performance%20maximization" title=" autonomous performance maximization"> autonomous performance maximization</a>, <a href="https://publications.waset.org/abstracts/search?q=autopilots" title=" autopilots"> autopilots</a> </p> <a href="https://publications.waset.org/abstracts/35994/increasing-performance-of-autopilot-guided-small-unmanned-helicopter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35994.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">582</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">24</span> On the Relation between λ-Symmetries and μ-Symmetries of Partial Differential Equations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Teoman%20Ozer">Teoman Ozer</a>, <a href="https://publications.waset.org/abstracts/search?q=Ozlem%20Orhan"> Ozlem Orhan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study deals with symmetry group properties and conservation laws of partial differential equations.

After biopolishing process, the fuzzes ripped by cellulase enzymes cannot be thoroughly removed from fabric surface, they remain on the fabric or fiber surface; accordingly disturb the user and lead to decrease in productivity of drying process. The main objective of this study is to develop a method for removing weakened fuzz fibers and surface pills from biofinished fabric surface before drying process. Fuzzes in the lattice structure of fabric were completely removed from the internal structure of the fabric by air blowing. The presence of fuzzes leads to problems with formation of pilling and faded appearance; the removal of fuzzes from the fabric results in reduced tendency to pill formation, cleaner, smoother and softer surface, improved handling properties of fabric with maintaining original color. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biopolishing" title="biopolishing">biopolishing</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzz%20fiber" title=" fuzz fiber"> fuzz fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=weakened%20fiber" title=" weakened fiber"> weakened fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=biofinished%20cotton%20fabric" title=" biofinished cotton fabric"> biofinished cotton fabric</a> </p> <a href="https://publications.waset.org/abstracts/56079/analysis-of-process-for-solution-of-fiber-ends-after-biopolishing-on-the-surface-of-cotton-knit-fabric" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56079.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">380</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">22</span> Understanding Tacit Knowledge and Its Role in Military Organizations: Methods of Managing Tacit Knowledge</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Erhan%20Orhan">M.

Health, by increasing the productivity of labor, contributes to economic growth. Therefore, countries should give the necessary emphasis to health services. The primary aim of this study is to analyze the changes occurring in health services in Turkey by examining the developments in the sector. In this scope, the second aim of the study is to reveal the place of health expenditures in the Turkish economy. As a result of the analysis in the dataset, in which the 1999-2013 periods is considered, it was determined that some increase in health expenditures took place and that the increase in the share of health expenditures in GDP was too small. Furthermore, analysis of the results points out that in financing health expenditures, the public sector is prominent compared to the private sector. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=health" title="health">health</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20service" title=" health service"> health service</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20expenditures" title=" health expenditures"> health expenditures</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkey" title=" Turkey"> Turkey</a> </p> <a href="https://publications.waset.org/abstracts/49597/health-expenditure-and-its-place-in-economy-the-case-of-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49597.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">368</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">19</span> Acidic Dye Removal From Aqueous Solution Using Heat Treated and Polymer Modified Waste Containing Boron Impurity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asim%20Olgun">Asim Olgun</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Kara"> Ali Kara</a>, <a href="https://publications.waset.org/abstracts/search?q=Vural%20Butun"> Vural Butun</a>, <a href="https://publications.waset.org/abstracts/search?q=Pelin%20Sevinc"> Pelin Sevinc</a>, <a href="https://publications.waset.org/abstracts/search?q=Merve%20Gungor"> Merve Gungor</a>, <a href="https://publications.waset.org/abstracts/search?q=Orhan%20Ornek"> Orhan Ornek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, we investigated the possibility of using waste containing boron impurity (BW) as an adsorbent for the removal of Orange 16 from aqueous solution.

The polymer modified sample having the highest positive zeta potential was used as an adsorbent. Batch adsorption studies were carried out. The operating variables studied were the initial dye concentration, contact time, solution pH, and adsorbent dosage. It was found that the dye adsorption largely depends on the initial pH of the solution with maximum uptake occurring at pH 3. The adsorption followed pseudo-second-order kinetics and the isotherm fit well to the Langmuir model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=zeta%20potential" title="zeta potential">zeta potential</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption" title=" adsorption"> adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=Orange%2016" title=" Orange 16"> Orange 16</a>, <a href="https://publications.waset.org/abstracts/search?q=isotherms" title=" isotherms"> isotherms</a> </p> <a href="https://publications.waset.org/abstracts/94450/acidic-dye-removal-from-aqueous-solution-using-heat-treated-and-polymer-modified-waste-containing-boron-impurity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94450.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">196</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">18</span> Exploring the Relationship between the Concepts of Organization Culture and Organizational Justice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Orhan%20Sezgin">Orhan Sezgin</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Kursad%20Ordu"> Mehmet Kursad Ordu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In today’s business world, among a number of forces, employees are seen as the most important components in order to survive and achieve organizational goals successfully.

Lane detection is a vital step for ADAS. The performance of the lane detection process is critical to obtain a high accuracy lane departure warning system (LDWS). Challenging factors such as road cracks, erosion of lane markings, weather conditions might affect the performance of a lane detection system. In this paper, 1-D weighted filter based on row filtering to detect lane marking is proposed. 2-D input image is filtered by 1-D weighted filter considering four-pixel values located symmetrically around the center of candidate pixel. Performance evaluation is carried out by two metrics which are true positive rate (TPR) and false positive rate (FPR). Experimental results demonstrate that the proposed approach provides better lane marking detection accuracy compared to the previous methods while providing real-time processing performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lane%20marking%20filter" title="lane marking filter">lane marking filter</a>, <a href="https://publications.waset.org/abstracts/search?q=lane%20detection" title=" lane detection"> lane detection</a>, <a href="https://publications.waset.org/abstracts/search?q=ADAS" title=" ADAS"> ADAS</a>, <a href="https://publications.waset.org/abstracts/search?q=LDWS" title=" LDWS"> LDWS</a> </p> <a href="https://publications.waset.org/abstracts/90804/real-time-lane-marking-detection-using-weighted-filter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90804.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">193</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">16</span> Examining the Modular End of Line Control Unit Design Criteria for Vehicle Sliding Door System Slide Profile</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Orhan%20Kurtulu%C5%9F">Orhan Kurtuluş</a>, <a href="https://publications.waset.org/abstracts/search?q=C%C3%BCneyt%20Yavuz"> Cüneyt Yavuz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The end of the line controls of the finished products in the automotive industry is important. The control that has been conducted with the manual methods for the sliding doors tracks is not sufficient and faulty products cannot be identified. As a result, the customer has the faulty products. In the scope of this study, the design criteria of the PLC integrated modular end of line control unit has been examined, designed and manufactured to make the control of the 10 different track profile to 2 different vehicles with an objective to minimize the salvage costs by obtaining more sensitive, certain and accurate measurement results. In the study that started with literature and patent review, the design inputs have been specified, the technical concept has been developed, computer supported mechanic design, control system and automation design, design review and design improvement have been made. Laser analog sensors at high sensitivity, probes and modular blocks have been used in the unit. The measurement has been conducted in the system and it is observed that measurement results are more sensitive than the previous methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=control%20unit%20design" title="control unit design">control unit design</a>, <a href="https://publications.waset.org/abstracts/search?q=end%20of%20line" title=" end of line"> end of line</a>, <a href="https://publications.waset.org/abstracts/search?q=modular%20design" title=" modular design"> modular design</a>, <a href="https://publications.waset.org/abstracts/search?q=sliding%20door%20system" title=" sliding door system"> sliding door system</a> </p> <a href="https://publications.waset.org/abstracts/35415/examining-the-modular-end-of-line-control-unit-design-criteria-for-vehicle-sliding-door-system-slide-profile" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35415.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">445</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">15</span> Polarity Classification of Social Media Comments in Turkish </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Migena%20Ceyhan">Migena Ceyhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Zeynep%20Orhan"> Zeynep Orhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimitrios%20Karras"> Dimitrios Karras</a> </p> <p class="card-text"><strong>Abstract:</strong></p> People in modern societies are continuously sharing their experiences, emotions, and thoughts in different areas of life. The information reaches almost everyone in real-time and can have an important impact in shaping people’s way of living. This phenomenon is very well recognized and advantageously used by the market representatives, trying to earn the most from this means. Given the abundance of information, people and organizations are looking for efficient tools that filter the countless data into important information, ready to analyze. This paper is a modest contribution in this field, describing the process of automatically classifying social media comments in the Turkish language into positive or negative. Once data is gathered and preprocessed, feature sets of selected single words or groups of words are build according to the characteristics of language used in the texts. These features are used later to train, and test a system according to different machine learning algorithms (Naïve Bayes, Sequential Minimal Optimization, J48, and Bayesian Linear Regression). The resultant high accuracies can be important feedback for decision-makers to improve the business strategies accordingly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=feature%20selection" title="feature selection">feature selection</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20language%20processing" title=" natural language processing"> natural language processing</a>, <a href="https://publications.waset.org/abstracts/search?q=sentiment%20analysis" title=" sentiment analysis"> sentiment analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20media%20reviews" title=" social media reviews"> social media reviews</a> </p> <a href="https://publications.waset.org/abstracts/129050/polarity-classification-of-social-media-comments-in-turkish" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129050.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">146</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">14</span> Reading Knowledge Development and Its Phases with Generation Z</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Onur%20%C3%96zdemir">Onur Özdemir</a>, <a href="https://publications.waset.org/abstracts/search?q=M.Erhan%20ORHAN"> M.Erhan ORHAN</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Knowledge Development (KD) is just one of the important phases of Knowledge Management (KM). KD is the phase in which intelligence is used to see the big picture. In order to understand whether information is important or not, we have to use the intelligence cycle that includes four main steps: aiming, collecting data, processing and utilizing. KD also needs these steps. To make a precise decision, the decision maker has to be aware of his subordinates’ ideas. If the decision maker ignores the ideas of his subordinates or participants of the organization, it is not possible for him to get the target. KD is a way of using wisdom to accumulate the puzzle. If the decision maker does not bring together the puzzle pieces, he cannot get the big picture, and this shows its effects on the battlefield. In order to understand the battlefield, the decision maker has to use the intelligence cycle. To convert information to knowledge, KD is the main means for the intelligence cycle. On the other hand, the “Z Generation” born after the millennium are really the game changers. They have different attitudes from their elders. Their understanding of life is different - the definition of freedom and independence have different meanings to them than others. Decision makers have to consider these factors and rethink their decisions accordingly. This article tries to explain the relation between KD and Generation Z. KD is the main method of target managing. But if leaders neglect their people, the world will be seeing much more movements like the Arab Spring and other insurgencies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knowledge%20development" title="knowledge development">knowledge development</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20management" title=" knowledge management"> knowledge management</a>, <a href="https://publications.waset.org/abstracts/search?q=generation%20Z" title=" generation Z"> generation Z</a>, <a href="https://publications.waset.org/abstracts/search?q=intelligence%20cycle" title=" intelligence cycle "> intelligence cycle </a> </p> <a href="https://publications.waset.org/abstracts/19492/reading-knowledge-development-and-its-phases-with-generation-z" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19492.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">517</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">13</span> Radio Frequency Identification System and Its Effect on Retailing Sector</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ay%C5%9Fe%20%C3%87oban">Ayşe Çoban</a>, <a href="https://publications.waset.org/abstracts/search?q=Orhan%20%C3%87oban"> Orhan Çoban</a>, <a href="https://publications.waset.org/abstracts/search?q=Murat%20Birekul"> Murat Birekul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the effects of radio frequency identification system on the retailing sector were theoretically analysed. The technology of Radio Frequency Identification (RFID) is a method enabling to identify the objects individually and automatically, using radio frequency. RFID generally consists of a tag and reader. RFID tags can be programmed to receive, store, and send the information of object such as Electronic Product Code (EPC). Having read the tags placed on product by the reader, the information associated with the management of supply chain can be automatically recorded and replaced. Recently, RFID technology used in many areas has particularly important effects on the businesses that are active in the retailing sector. The most important disadvantage of this technology is that the cost of installation and operation is higher compared to its alternatives. However, it provides important advantages to the business enterprises in the application process. At present, it is especially adopted by the large sized enterprises and with chain stores in the international areas. The application results point out that RFID technology provides business enterprises with the important competitive advantage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RFID" title="RFID">RFID</a>, <a href="https://publications.waset.org/abstracts/search?q=retailing%20sector" title=" retailing sector"> retailing sector</a>, <a href="https://publications.waset.org/abstracts/search?q=RFID%20technologies" title=" RFID technologies"> RFID technologies</a>, <a href="https://publications.waset.org/abstracts/search?q=electronic%20product%20code" title=" electronic product code"> electronic product code</a> </p> <a href="https://publications.waset.org/abstracts/6949/radio-frequency-identification-system-and-its-effect-on-retailing-sector" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6949.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">386</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">12</span> Synthesis and Evaluation of Antioxidant Behavior of Some Indole-Based Melatonin Derivatives</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eddy%20Neuhaus">Eddy Neuhaus</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanif%20Shirinzadeh"> Hanif Shirinzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Cigdem%20Karaaslan"> Cigdem Karaaslan</a>, <a href="https://publications.waset.org/abstracts/search?q=Elif%20Ince"> Elif Ince</a>, <a href="https://publications.waset.org/abstracts/search?q=Hande%20Gurer-Orhan"> Hande Gurer-Orhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sibel%20Suzen"> Sibel Suzen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reactive oxygen species (ROS) and oxidative stress can cause fatal damage to essential cell structures, including DNA. It is known that use of antioxidants could be advantageous in the prevention of various diseases such as cancer, cardiovascular diseases and neurodegenerative disorders. Since antioxidant properties of the indole ring-containing melatonin (MLT) has been described and evaluated, MLT-related compounds such as MLT metabolites and synthetic analogues are under investigation to determine which exhibit the highest activity with the lowest side-effects. Owing to indole and hydrazones appealing physiological properties and are mostly found in numerous biologically active compounds a series of indole-7-carbaldehyde hydrazone derivatives were synthesized, characterized and in vitro antioxidant activity was investigated by evaluating their reducing effect against oxidation of a redox-sensitive fluorescent probe. Cytotoxicity potential of all indole-based MLT analogues was investigated both by lactate dehydrogenase leakage assay and by MTT assay.

Current treatment approaches in this disease with the major therapeutic strategy are based on the AChE and BChE inhibition. On the other hand, tyrosinase inhibition has become a target for the treatment of Parkinson’s disease (PD) since this enzyme may play a role in neuromelanin formation in the human brain and could be critical in the formation of dopamine neurotoxicity associated with neurodegeneration linked to PD. Also benzoxazoles are structural isosteres of natural nucleotides that can interact with biopolymers so that benzoxazoles showed a lot of different biological activities. In this study, a series of 2,5-disubstituted-benzoxazole derivatives were synthesized and were evaluated as possible inhibitors of acetylcholinesterase (AChE) / butyrylcholinesterase (BChE) and tyrosinase. The results demonstrated that the compounds exhibited a weak spectrum of AChE / BChE inhibitory activity ranging between 3.92% - 54.32% except compound 8 which showed no activity against AChE and compound 4 which showed no activity against BChE at the specified molar concentrations. Also, the compounds indicated lower than tyrosinase inhibitory activity of ranging between 8.14% - 22.90% to that of reference (kojic acid). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AChE%20and%20BChE%20inhibition" title="AChE and BChE inhibition">AChE and BChE inhibition</a>, <a href="https://publications.waset.org/abstracts/search?q=Alzheimer%E2%80%99s%20disease" title=" Alzheimer’s disease"> Alzheimer’s disease</a>, <a href="https://publications.waset.org/abstracts/search?q=benzoxazoles" title=" benzoxazoles"> benzoxazoles</a>, <a href="https://publications.waset.org/abstracts/search?q=tyrosinase%20inhibition" title=" tyrosinase inhibition"> tyrosinase inhibition</a> </p> <a href="https://publications.waset.org/abstracts/66790/synthesis-and-biological-evaluation-of-some-benzoxazole-derivatives-as-inhibitors-of-acetylcholinesterase-butyrylcholinesterase-and-tyrosinase" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66790.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">341</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">10</span> Renewable Energy Potential of Diluted Poultry Manure during Ambient Anaerobic Stabilisation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cigdem%20Yangin-Gomec">Cigdem Yangin-Gomec</a>, <a href="https://publications.waset.org/abstracts/search?q=Aigerim%20Jaxybayeva"> Aigerim Jaxybayeva</a>, <a href="https://publications.waset.org/abstracts/search?q=Orhan%20Ince"> Orhan Ince</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the anaerobic treatability of chicken manure diluted with tap water (with an influent feed ratio of 1 kg of fresh chicken manure to 6 liter of tap water) was investigated in a lab-scale anaerobic sludge bed (ASB) reactor inoculated with the granular sludge already adapted to chicken manure. The raw waste digested in this study was the manure from laying-hens having average total solids (TS) of about 30% with ca. 60% volatile content. The ASB reactor was fed semi-continuously at ambient operating temperature range (17-23<sup>◦</sup>C) at a HRT of 13 and 26 days for about 6 months, respectively. The respective average total and soluble chemical oxygen demand (COD) removals were ca. 90% and 75%, whereas average biomethane production rate was calculated ca. 180 lt per kg of COD<sub>removed</sub> from the ASB reactor at an average HRT of 13 days. Moreover, total suspended solids (TSS) and volatile suspended solids (VSS) in the influent were reduced more than 97%. Hence, high removals of the organic compounds with respective biogas production made anaerobic stabilization of the diluted chicken manure by ASB reactor at ambient operating temperatures viable. By this way, external heating up to 35<sup>◦</sup>C (i.e. anaerobic processes have been traditionally operated at mesophilic conditions) could be avoided in the scope of this study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ambient%20anaerobic%20digestion" title="ambient anaerobic digestion">ambient anaerobic digestion</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas%20recovery" title=" biogas recovery"> biogas recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=poultry%20manure" title=" poultry manure"> poultry manure</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a> </p> <a href="https://publications.waset.org/abstracts/40062/renewable-energy-potential-of-diluted-poultry-manure-during-ambient-anaerobic-stabilisation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40062.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">420</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">9</span> Multi-Layer Perceptron and Radial Basis Function Neural Network Models for Classification of Diabetic Retinopathy Disease Using Video-Oculography Signals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ceren%20Kaya">Ceren Kaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Okan%20Erkaymaz"> Okan Erkaymaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Orhan%20Ayar"> Orhan Ayar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmut%20%C3%96zer"> Mahmut Özer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Diabetes Mellitus (Diabetes) is a disease based on insulin hormone disorders and causes high blood glucose. Clinical findings determine that diabetes can be diagnosed by electrophysiological signals obtained from the vital organs. 'Diabetic Retinopathy' is one of the most common eye diseases resulting on diabetes and it is the leading cause of vision loss due to structural alteration of the retinal layer vessels. In this study, features of horizontal and vertical Video-Oculography (VOG) signals have been used to classify non-proliferative and proliferative diabetic retinopathy disease. Twenty-five features are acquired by using discrete wavelet transform with VOG signals which are taken from 21 subjects. Two models, based on multi-layer perceptron and radial basis function, are recommended in the diagnosis of Diabetic Retinopathy. The proposed models also can detect level of the disease. We show comparative classification performance of the proposed models. Our results show that proposed the RBF model (100%) results in better classification performance than the MLP model (94%). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diabetic%20retinopathy" title="diabetic retinopathy">diabetic retinopathy</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete%20wavelet%20transform" title=" discrete wavelet transform"> discrete wavelet transform</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-layer%20perceptron" title=" multi-layer perceptron"> multi-layer perceptron</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20basis%20function" title=" radial basis function"> radial basis function</a>, <a href="https://publications.waset.org/abstracts/search?q=video-oculography%20%28VOG%29" title=" video-oculography (VOG)"> video-oculography (VOG)</a> </p> <a href="https://publications.waset.org/abstracts/78748/multi-layer-perceptron-and-radial-basis-function-neural-network-models-for-classification-of-diabetic-retinopathy-disease-using-video-oculography-signals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78748.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">259</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">8</span> Evaluation of the Relationship between Fluorosis and Stylohyoid Ligament Calcification Detected on Panoramic Radiograph</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Recep%20Duzsoz">Recep Duzsoz</a>, <a href="https://publications.waset.org/abstracts/search?q=Ozlem%20Gormez"> Ozlem Gormez</a>, <a href="https://publications.waset.org/abstracts/search?q=Umit%20Memis"> Umit Memis</a>, <a href="https://publications.waset.org/abstracts/search?q=Selma%20%20Demer"> Selma Demer</a>, <a href="https://publications.waset.org/abstracts/search?q=Hikmet%20Orhan"> Hikmet Orhan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Stylohyoid ligament is a connective tissue extending from apex of the styloid process to small horn of the hyoid bone. The normal length of styloid process ranges from 20 to 30 mm and measurements more than 30 mm is named stylohyoid ligament calcification (SLC). Fluorosis is a health problem that arises in individuals who intake large amounts of fluor long periods of time. The aim of this study was to investigate the effects of fluorosis on SLC. This study has been conducted on 100 patients who had SLC detected on panoramic radiograph. The study group was consisted of 50 patients with dental fluorosis and control group was consisted of 50 patients without dental fluorosis. Length and thickness of SLC were measured and the type of SLC was determined on panoramic radiographs. There was no statistically significant differences between the study and control group for SLC length, thickness and type. The thickness of left and right SLC of severe dental fluorosis group was statistically significant higher than moderate dental fluorosis group (p < 0,05). Cervicopharyngeal trauma, tonsillectomy, endocrine disease in menopause, persistent mesenchymal tissue, mechanical stress have reported as etiology of SLC in the literature and studies are still ongoing. It was reported that fluorosis as a factor on calcification of some ligaments in body (posterior longitudunal ligament, ligamentum flavum and transverse atlantal ligament) previously but relationship between fluorosis with SLC was not investigated. Our study is unique because it is the first study on SLC thickness measurements on panoramic radiographs and the relationship between fluorosis and SLC to our knowledge. According to the obtained results, it is thought that fluorosis may have an effect on SLC in thickness due to the relationship between dental fluorosis severity with SLC thickness and this study will contribute to the progress of the future studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calcification" title="calcification">calcification</a>, <a href="https://publications.waset.org/abstracts/search?q=fluorosis" title=" fluorosis"> fluorosis</a>, <a href="https://publications.waset.org/abstracts/search?q=ligament" title=" ligament"> ligament</a>, <a href="https://publications.waset.org/abstracts/search?q=stylohyoid" title=" stylohyoid"> stylohyoid</a> </p> <a href="https://publications.waset.org/abstracts/64788/evaluation-of-the-relationship-between-fluorosis-and-stylohyoid-ligament-calcification-detected-on-panoramic-radiograph" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64788.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">224</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">7</span> Obsession Unveiled: A Freud’s Psychoanalytical Analysis of Protagonist Fixations in Nabokov’s Lolita and Pamuk’s The Museum of Innocence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kamilya%20Khamitova">Kamilya Khamitova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study analyzes the overarching theme of obsession as portrayed through the two protagonists, Humbert Humbert and Kemal, in Vladimir Nabokov's Lolita and Orhan Pamuk's The Museum of Innocence through the lens of Freudian psychoanalytical theory of “transference.” Their obsessions are channeled into various forms of artistic expression following the loss of their beloved Lolita and Füsun. Employing psychoanalytical literary criticism, firmly grounded in the classical era of psychoanalysis, as pioneered by Sigmund Freud, this research explores the characters' psyches, revealing the concealed desires, conflicts, and symbolic manifestations within their relentless obsessions. The aim of this study is to unravel the psychological complexities of obsession, shedding light on the motivations and behaviors of Humbert and Kemal within the context of their respective narratives. Methodologically, this research employs close textual analysis of the novels, dissecting the protagonists' thoughts, actions, and artistic expressions. Through the lens of Freud's fundamental concept of “transference,” this analysis uncovers the protagonists' mechanisms of projecting their desires onto unattainable objects of desire—Lolita and Füsun. Humbert's pursuit of Lolita mirrors his unresolved emotional traumas and attempts to recapture the lost object of his childhood. In contrast, Kemal's fixation on Füsun is a desperate desire to fill an existential void, address a sense of inadequacy, and construct a semblance of immortality through the meticulous preservation of his memories with her. By adopting a psychoanalytic lens, this research provides a richer understanding of the characters, themes, and symbolism inherent in their artistic expressions of devotion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artistic%20expression" title="artistic expression">artistic expression</a>, <a href="https://publications.waset.org/abstracts/search?q=psychoanalysis%20of%20obsession" title=" psychoanalysis of obsession"> psychoanalysis of obsession</a>, <a href="https://publications.waset.org/abstracts/search?q=Sigmund%20Freud" title=" Sigmund Freud"> Sigmund Freud</a>, <a href="https://publications.waset.org/abstracts/search?q=transference" title=" transference"> transference</a> </p> <a href="https://publications.waset.org/abstracts/173575/obsession-unveiled-a-freuds-psychoanalytical-analysis-of-protagonist-fixations-in-nabokovs-lolita-and-pamuks-the-museum-of-innocence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173575.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">160</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">6</span> The Effects of Semi-Public Spaces with Distinctive Functions on the Urban Space Quality</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Melike%20Orhan">Melike Orhan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Along with impetuous physical change, configuration and increase in the density of cities, urban public spaces have started to become a transition area rather than spaces to inhabit. The insufficiency of public spaces, one of the most significant components of a city, where communal life is maintained and the decrease in the quality of urban spaces have led to an increase in the use of semi-public spaces as urban space. Semi-public spaces are those that ensure transition between private and public spaces and can be seen, observed, reached and used by urban-dwellers. Humans are in a constant relation to their surroundings and care for integration as part of their surroundings. Semi-public spaces providing balance for the individual between private spaces (structures) and urban-public spaces make this integration easier. Spaces with a semi-public characteristic serve for a particular neighboring unit and the user (i.e. common use areas in residential spaces and dwellings, common outdoor areas situated between office buildings, and etc.) These spaces, whose density of usage is increased with distinctive functions and activities, gain different attributions according to the characteristics of the urban space they are located in (commercial, residential, touristic, and etc.) and to the functions of the structures with which they are in relation. At the same time, they begin to serve other neighboring units along with an increase in public usage. As a result, the interaction between environment-space-structure-humans changes, which directly affects the urban space quality. The aim of this study is to determine how and depending on what characteristics the public usage density of semi-public spaces change and to put forth the effects of this change on the urban environment it is located in and to designate its role in terms of 'urban space quality'. In conclusion, within the scope of this study, semi-public spaces located in urban spaces with distinctive functions will be explored through examples, and the effects of these spaces with altered public usage and density on urban space and quality of life will be put forward. Accordingly, applicable criteria will be determined by means of semi-public spaces oriented at increasing and sustaining the quality of urban space. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=semi-public%20spaces" title="semi-public spaces">semi-public spaces</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20public%20spaces" title=" urban public spaces"> urban public spaces</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20space%20quality" title=" urban space quality"> urban space quality</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20usage" title=" public usage"> public usage</a> </p> <a href="https://publications.waset.org/abstracts/111371/the-effects-of-semi-public-spaces-with-distinctive-functions-on-the-urban-space-quality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111371.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">239</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">5</span> A Preliminary Finding Regarding Nutrition Information Needs among Family Physicians in Turkey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Nur%20Baran%20Aksakal">F.

The role of nutrition in medical education is to provide information about the relationship between healthy nutrition and malnutrition as well as diet-related non-communicable diseases. Considering the information pollution experienced in the field of nutrition and health in the society, it is seen that more than half of the population receives information from family physicians as the closest counseling unit. However, postgraduate nutrition education programs for physicians and other health professionals who wish to improve their current knowledge of the role of nutrition communication in the prevention and management of chronic diseases are limited worldwide. However, nutrition courses are either not included in the undergraduate medical education curriculum of physicians or they are insufficient. Based on this need, the main aim of the study group was to develop a "Nutrition and Nutrition Communication Training for Physicians" program that would be conducted in cooperation with the Sabri Ülker Foundation and the Federation of Family Physicians Associations (AHEF). This program is the first online nutrition and nutrition communication information platform for physicians in Turkey. This program aims to present the concept of adequate and balanced nutrition to physicians, the importance of nutrition in diseases with scientific data, and to gain communication skills that may be necessary while transferring scientific information to the public. A needs assessment questionnaire was applied to identify pre-program training needs. A study plan was made to allow the participation of all family physicians in the population, and a complete inventory was targeted. In other words, we aimed to reach the whole source without taking a section of the population. Participation in the training is based on volunteerism. The needs assessment study is conducted using 25,102 family physicians for whom email addresses are available. The online questionnaire was sent to all the family physicians with a reminder email one week after the first one, and 1308 responded. Considering the topics determined, a training program was prepared for family physicians under eight online training titles, starting in March 2022, and conducted once every two weeks. The number of audience members present at each session was between 1217 and 1673, and a minimum of 17 and a maximum of 53 questions were received in each session. We strongly believe that to prevent individuals' health problems and to have better control over chronic diseases, the information level of physicians should be increased via these kinds of interventions, and better collaboration between family physicians and dieticians should be established. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nutrition%20communication" title="nutrition communication">nutrition communication</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrition%20training" title=" nutrition training"> nutrition training</a>, <a href="https://publications.waset.org/abstracts/search?q=communication" title=" communication"> communication</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrition" title=" nutrition"> nutrition</a> </p> <a href="https://publications.waset.org/abstracts/156776/a-preliminary-finding-regarding-nutrition-information-needs-among-family-physicians-in-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156776.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">98</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">4</span> The Effect of Paper Based Concept Mapping on Students' Academic Achievement and Attitude in Science Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Orhan%20Ak%C4%B1no%C4%9Flu">Orhan Akınoğlu</a>, <a href="https://publications.waset.org/abstracts/search?q=Arif%20%C3%87%C3%B6mek"> Arif Çömek</a>, <a href="https://publications.waset.org/abstracts/search?q=Ersin%20Elmac%C4%B1"> Ersin Elmacı</a>, <a href="https://publications.waset.org/abstracts/search?q=Tu%C4%9Fba%20G%C3%BCndo%C4%9Fdu"> Tuğba Gündoğdu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The concept map is known to be a powerful tool to organize the ideas and concepts of an individuals’ mind. This tool is a kind of visual map that illustrates the relationships between the concepts of a certain subject. The effect of concept mapping on cognitive and affective qualities is one of the research topics among educational researchers for last decades. We educators want to utilize it both as an instructional tool or an assessment tool in classes. For that reason, this study aimed to determine the effect of concept mapping as a learning strategy in science classes on students’ academic achievement and attitude. The research employed a randomized pre-test post-test control group design. Data collected from 60 sixth grade students participated in the study from a randomly selected primary school in Turkey. Sixth-grade classes of the school were analyzed according to students’ academic achievement, science attitude, gender, mathematics, science courses grades, and their GPAs before the implementation. Two of the classes found to be equivalent (t=0,983, p>0,05) and one of them was defined as experimental and the other one control group randomly. During a 5-weeks period, the experimental group students (N=30) used the paper-based concept mapping method while the control group students (N=30) were taught with the traditional approach according to the science and technology education curriculum for light and sound subject. Both groups were taught by the same teacher who is experienced using concept mapping in science classes. Before the implementation, the teacher explained the theory of the concept maps and showed how to create paper-based concept mapping individually to the experimental group students for two hours. Then for two following hours she asked them to create some concept maps related to their former science subjects and gave them feedback by reviewing their concept maps to be sure that they can create during the implementation. The data were collected by science achievement test, science attitude scale and personal information form. Science achievement test and science attitude scale were implemented as pre-test and post-test while personal information form was implemented just as once. The reliability coefficient of the achievement test was KR20=0,76 and Cronbach’s Alpha of the attitude scale was 0,89. SPSS statistical software was used to analyze the data. According to the results, there was a statistically significant difference between the experimental and control group for academic achievement but not for attitude. The experimental group had significantly greater gains from academic achievement test than the control group (t=0,02, p<0,05). The findings showed that the paper-and-pencil concept mapping can be used as an effective method for students’ academic achievement in science classes. The results have implications for further researches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concept%20mapping" title="concept mapping">concept mapping</a>, <a href="https://publications.waset.org/abstracts/search?q=science%20education" title=" science education"> science education</a>, <a href="https://publications.waset.org/abstracts/search?q=constructivism" title=" constructivism"> constructivism</a>, <a href="https://publications.waset.org/abstracts/search?q=academic%20achievement" title=" academic achievement"> academic achievement</a>, <a href="https://publications.waset.org/abstracts/search?q=science%20attitude" title=" science attitude"> science attitude</a> </p> <a href="https://publications.waset.org/abstracts/30478/the-effect-of-paper-based-concept-mapping-on-students-academic-achievement-and-attitude-in-science-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30478.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">408</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">3</span> Comparing Remote Sensing and in Situ Analyses of Test Wheat Plants as Means for Optimizing Data Collection in Precision Agriculture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Endalkachew%20Abebe%20Kebede">Endalkachew Abebe Kebede</a>, <a href="https://publications.waset.org/abstracts/search?q=Bojin%20Bojinov"> Bojin Bojinov</a>, <a href="https://publications.waset.org/abstracts/search?q=Andon%20Vasilev%20Andonov"> Andon Vasilev Andonov</a>, <a href="https://publications.waset.org/abstracts/search?q=Orhan%20Dengiz"> Orhan Dengiz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Remote sensing has a potential application in assessing and monitoring the plants' biophysical properties using the spectral responses of plants and soils within the electromagnetic spectrum. However, only a few reports compare the performance of different remote sensing sensors against in-situ field spectral measurement. The current study assessed the potential applications of open data source satellite images (Sentinel 2 and Landsat 9) in estimating the biophysical properties of the wheat crop on a study farm found in the village of OvchaMogila. A Landsat 9 (30 m resolution) and Sentinel-2 (10 m resolution) satellite images with less than 10% cloud cover have been extracted from the open data sources for the period of December 2021 to April 2022. An Unmanned Aerial Vehicle (UAV) has been used to capture the spectral response of plant leaves. In addition, SpectraVue 710s Leaf Spectrometer was used to measure the spectral response of the crop in April at five different locations within the same field. The ten most common vegetation indices have been selected and calculated based on the reflectance wavelength range of remote sensing tools used. The soil samples have been collected in eight different locations within the farm plot. The different physicochemical properties of the soil (pH, texture, N, P₂O₅, and K₂O) have been analyzed in the laboratory. The finer resolution images from the UAV and the Leaf Spectrometer have been used to validate the satellite images. The performance of different sensors has been compared based on the measured leaf spectral response and the extracted vegetation indices using the five sampling points. A scatter plot with the coefficient of determination (R2) and Root Mean Square Error (RMSE) and the correlation (r) matrix prepared using the corr and heatmap python libraries have been used for comparing the performance of Sentinel 2 and Landsat 9 VIs compared to the drone and SpectraVue 710s spectrophotometer. The soil analysis revealed the study farm plot is slightly alkaline (8.4 to 8.52). The soil texture of the study farm is dominantly Clay and Clay Loam.The vegetation indices (VIs) increased linearly with the growth of the plant. Both the scatter plot and the correlation matrix showed that Sentinel 2 vegetation indices have a relatively better correlation with the vegetation indices of the Buteo dronecompared to the Landsat 9. The Landsat 9 vegetation indices somewhat align better with the leaf spectrometer. Generally, the Sentinel 2 showed a better performance than the Landsat 9. Further study with enough field spectral sampling and repeated UAV imaging is required to improve the quality of the current study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=landsat%209" title="landsat 9">landsat 9</a>, <a href="https://publications.waset.org/abstracts/search?q=leaf%20spectrometer" title=" leaf spectrometer"> leaf spectrometer</a>, <a href="https://publications.waset.org/abstracts/search?q=sentinel%202" title=" sentinel 2"> sentinel 2</a>, <a href="https://publications.waset.org/abstracts/search?q=UAV" title=" UAV"> UAV</a> </p> <a href="https://publications.waset.org/abstracts/152005/comparing-remote-sensing-and-in-situ-analyses-of-test-wheat-plants-as-means-for-optimizing-data-collection-in-precision-agriculture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152005.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">107</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">2</span> Evaluating Urban City Indices: A Study for Investigating Functional Domains, Indicators and Integration Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatih%20Gundogan">Fatih Gundogan</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatih%20Kafali"> Fatih Kafali</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdullah%20Karadag"> Abdullah Karadag</a>, <a href="https://publications.waset.org/abstracts/search?q=Alper%20Baloglu"> Alper Baloglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ersoy%20Pehlivan"> Ersoy Pehlivan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Eruyar"> Mustafa Eruyar</a>, <a href="https://publications.waset.org/abstracts/search?q=Osman%20Bayram"> Osman Bayram</a>, <a href="https://publications.waset.org/abstracts/search?q=Orhan%20Karademiroglu"> Orhan Karademiroglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Wasim%20Shoman"> Wasim Shoman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays many cities around the world are investing their efforts and resources for the purpose of facilitating their citizen’s life and making cities more livable and sustainable by implementing newly emerged phenomena of smart city. For this purpose, related research institutions prepare and publish smart city indices or benchmarking reports aiming to measure the city’s current ‘smartness’ status. Several functional domains, various indicators along different selection and calculation methods are found within such indices and reports. The selection criteria varied for each institution resulting in inconsistency in the ranking and evaluating. This research aims to evaluate the impact of selecting such functional domains, indicators and calculation methods which may cause change in the rank. For that, six functional domains, i.e. Environment, Mobility, Economy, People, Living and governance, were selected covering 19 focus areas and 41 sub-focus (variable) areas. 60 out of 191 indicators were also selected according to several criteria. These were identified as a result of extensive literature review for 13 well known global indices and research and the ISO 37120 standards of sustainable development of communities. The values of the identified indicators were obtained from reliable sources for ten cities. The values of each indicator for the selected cities were normalized and standardized to objectively investigate the impact of the chosen indicators. Moreover, the effect of choosing an integration method to represent the values of indicators for each city is investigated by comparing the results of two of the most used methods i.e. geometric aggregation and fuzzy logic. The essence of these methods is assigning a weight to each indicator its relative significance. However, both methods resulted in different weights for the same indicator. As a result of this study, the alternation in city ranking resulting from each method was investigated and discussed separately. Generally, each method illustrated different ranking for the selected cities. However, it was observed that within certain functional areas the rank remained unchanged in both integration method. Based on the results of the study, it is recommended utilizing a common platform and method to objectively evaluate cities around the world. The common method should provide policymakers proper tools to evaluate their decisions and investments relative to other cities. Moreover, for smart cities indices, at least 481 different indicators were found, which is an immense number of indicators to be considered, especially for a smart city index. Further works should be devoted to finding mutual indicators representing the index purpose globally and objectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=functional%20domain" title="functional domain">functional domain</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20city%20index" title=" urban city index"> urban city index</a>, <a href="https://publications.waset.org/abstracts/search?q=indicator" title=" indicator"> indicator</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/97286/evaluating-urban-city-indices-a-study-for-investigating-functional-domains-indicators-and-integration-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97286.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">147</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">1</span> Early Diagnosis of Myocardial Ischemia Based on Support Vector Machine and Gaussian Mixture Model by Using Features of ECG Recordings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Merve%20Begum%20Terzi">Merve Begum Terzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Orhan%20Arikan"> Orhan Arikan</a>, <a href="https://publications.waset.org/abstracts/search?q=Adnan%20Abaci"> Adnan Abaci</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Candemir"> Mustafa Candemir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Acute myocardial infarction is a major cause of death in the world. Therefore, its fast and reliable diagnosis is a major clinical need. ECG is the most important diagnostic methodology which is used to make decisions about the management of the cardiovascular diseases. In patients with acute myocardial ischemia, temporary chest pains together with changes in ST segment and T wave of ECG occur shortly before the start of myocardial infarction. In this study, a technique which detects changes in ST/T sections of ECG is developed for the early diagnosis of acute myocardial ischemia. For this purpose, a database of real ECG recordings that contains a set of records from 75 patients presenting symptoms of chest pain who underwent elective percutaneous coronary intervention (PCI) is constituted. 12-lead ECG’s of the patients were recorded before and during the PCI procedure. Two ECG epochs, which are the pre-inflation ECG which is acquired before any catheter insertion and the occlusion ECG which is acquired during balloon inflation, are analyzed for each patient. By using pre-inflation and occlusion recordings, ECG features that are critical in the detection of acute myocardial ischemia are identified and the most discriminative features for the detection of acute myocardial ischemia are extracted. A classification technique based on support vector machine (SVM) approach operating with linear and radial basis function (RBF) kernels to detect ischemic events by using ST-T derived joint features from non-ischemic and ischemic states of the patients is developed. The dataset is randomly divided into training and testing sets and the training set is used to optimize SVM hyperparameters by using grid-search method and 10fold cross-validation. SVMs are designed specifically for each patient by tuning the kernel parameters in order to obtain the optimal classification performance results. As a result of implementing the developed classification technique to real ECG recordings, it is shown that the proposed technique provides highly reliable detections of the anomalies in ECG signals. Furthermore, to develop a detection technique that can be used in the absence of ECG recording obtained during healthy stage, the detection of acute myocardial ischemia based on ECG recordings of the patients obtained during ischemia is also investigated. For this purpose, a Gaussian mixture model (GMM) is used to represent the joint pdf of the most discriminating ECG features of myocardial ischemia. Then, a Neyman-Pearson type of approach is developed to provide detection of outliers that would correspond to acute myocardial ischemia. Neyman – Pearson decision strategy is used by computing the average log likelihood values of ECG segments and comparing them with a range of different threshold values. For different discrimination threshold values and number of ECG segments, probability of detection and probability of false alarm values are computed, and the corresponding ROC curves are obtained. The results indicate that increasing number of ECG segments provide higher performance for GMM based classification. Moreover, the comparison between the performances of SVM and GMM based classification showed that SVM provides higher classification performance results over ECG recordings of considerable number of patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ECG%20classification" title="ECG classification">ECG classification</a>, <a
