  • A methodology for implementation of the mechanistic-empirical rigid
           pavement design in Turkey

    • Authors: Mohammad Razeq SHAKHAN ; Ali TOPAL , Burak ŞENGÖZ
      Abstract: The Mechanistic-Empirical Pavement Design Guide (MEPDG) was emerged and calibrated based on the North American conditions for analysis and designing of flexible and rigid pavements. Implementing this guide in elsewhere needs evaluation using local data, if need be, the local calibration should be conducted to improve the accuracy of the pavement distress prediction models. State agencies and countries have followed different implementation methodologies to adopt the method. In this study, a methodology was developed for the implementation of the ME Rigid Pavement Design Guide in Turkey. This methodology can serve as a guide for local calibration of the MEPDG in Turkey as well as countries.

  • One-dimensional Center Symmetric Local Binary Pattern Based Epilepsy
           Detection Method

    • Authors: Serkan METİN
      Abstract: The diagnosis of epilepsy from the EEG signals is determined by the visual/manual evaluation performed by the neurologist. This evaluation process is laborious and evaluation results vary according to the experience level of neurologists. Therefore, automated systems that will be created using advanced signal processing techniques are important for diagnosis. In this study, a new feature extraction method is proposed using multiple kernel based one-dimensional center symmetric local binary pattern (1D-CSLBP) to identify epileptic seizures. To strengthen this method, levels have been created and multi-level feature extraction has been carried out. Discrete wavelet transform (DWT) was used to generate the levels and feature extraction was performed using the low pass filter coefficient (L bands) obtained at each level. Neighborhood component analysis (NCA) was used to select the most distinctive features. The obtained features are classified using the nearest neighbors (kNN) algorithm. A high performance method was obtained by using multiple kernel NCA and NCA. The 1D-CSLBP and NCA-based method has reached 100.0% accuracy in A-E, A-D-E, D-E, C-E situations.

  • Modelling a Static VAr Compensator consist of TCR and TSC

    • Authors: Onur TURAN ; Yavuz SARI
      Abstract: As an alternative to traditional solutions, systems that flexible alternating current transmission systems (FACTS) have been developed in order to make electrical energy systems more efficient, to improve stability and power quality, and these systems have been used in different parts of the world including our country. In general, FACTS can be described as systems providing voltage, impedance and phase angle control in AC systems. With the recent studies, the use of modern technology devices such as static VAr compensator and static synchronous compensator is becoming more common in order to ensure the energy quality in power systems. Furthermore, due to the developments in semiconductor technology, static VAr compensation systems have been started to be applied on medium and high voltage side. The most important feature of these systems is that they can compensate without needing reactive power from the grid. In this study, necessary reactive power required by the system provided by using a static VAr compensator consisting of thyristor-controlled reactor and thyristor switched capacitor structures. In the simulation studies, the reactive energy is supplied through the static compensator instead of the voltage source. In this way, unnecessary capacity utilization in the system was prevented. It is recommended to use static VAr compensators especially where there is unbalanced load and instant reactive power is required.

  • 4×4 Knight’s Graph Analysis by Modularity A Knight Graph
           Application

    • Authors: Serkan GÜLDAL
      Abstract: Modularity is a well-known technic to analyze graphs of datasets. The modularity divides the network into meaningful clusters. The clusters present the existence of shared properties between the nodes in the same cluster. In the present study, we analyze 4×4 knight graph by modularity to investigate 4-KCP solutions. Our investigation is completed for resolutions from 0.2 to 3.2. The maximum modularity score is 0.417 found (for resolution = 0.6, 0.8, 1, and 1.4). Moreover, resolution 1.4 is the optimum resolution to find some solutions of 4-KCP. Also, the analyses show resolution 0.2 is the best resolution to find all solutions of 4-KCP.

  • The Change of The Magnitude of The Electric Field Vector (EyE0) in The
           Ionosphere in The Magnetic Equator Through

    • Authors: Ali YEŞİL
      Abstract: In this study, the seasonal changes of (Ey/E0), which was obtained from the WKB (Wentzel, Kramers, Brillouin) solution, for (-300 ;300) geographic latitudes and (390,410,450,500,550 and 600 Km) altitudes in the equatorial anomaly region were investigated. (Ey/E0) ratio takes minimum value in latitudes, where the electron density is at maximum levels and takes maximum value in places where the electron density is at minimum levels, respectively. It is possible to say that in places where the electron density is at maximum, the wave transfers energy to the medium, otherwise it receives energy from the medium.

  • Correlation Based Regression Imputation (CBRI) Method for Missing Data
           Imputation

    • Authors: Uğur ÜRESİN
      Abstract: To complete missing values in a dataset is crucial for data mining and machine learning applications. If any parameter of a dataset has missing values, the values of the other parameters corresponding to those missing values should not be excluded from the dataset in order to prevent information in the dataset. Missing values should be handled carefully to avoid their affecting analyses and to prevent loss of information. There are many methods to predict missing values (imputation) that take into account other values of the relevant parameter, but these methods do not consider other parameters. In this study, an algorithm considering other parameters is proposed and its performance is compared with methods that calculate missing data without considering other parameters. The proposed method (CBRI) has been tested with a real dataset, and much more successful results have been obtained compared to the two commonly used imputation methods, mean imputation and median imputation.

  • Enhancing The Data Security by using Audio Steganography with Taylor
           Series Cryptosystem

    • Authors: Muharrem Tuncay GENÇOĞLU
      Abstract: Especially in recent years, the security of information and computer systems appears to be a very important issue. Because the heavily used communication network has made life easier as well as accompany serious security problems. To solve these problems, cryptography and steganography have been widely used. To present a more secure model for audios, a simple and secure stego-crypto method is presented. In this work, the hidden data is encrypted by the proposed Taylor series based encryption method and the encrypted data are hidden audio signals by applying the least significant bit (LSB) method. A real-world application is implemented in the proposed model. According to the results, the used encryption model is more efficient than AES. The results and findings demonstrated that this model can be used in a communication security system.

  • Energy and Exergy Analysis of Drying Behavior for a Fish

    • Authors: Murat ERDEM ; Fethi KAMIŞLI , Yasin VAROL , Hakan ÖZTOP
      Abstract: The drying of rainbow trout in a square cross-sectional drier is examined to analyze the system in terms of the energy and exergy by considering thin-layer drying approach. In the experiments, the inlet velocity of air was kept to be constant at 1.5 m/s while varying the temperature of inlet air of 38, 46 and 53 C with relative moisture ranged from 28 to 43 percent. At the beginning, moisture content of specimen (fish) on wet basis was found to be around 75 %. The energy analysis on the consumed energy for the drying process was performed by considering the energy balance. Moreover, the exergy analysis was actualized by considering the second law of thermodynamics to identify the efficiency of device and magnitude of energy losses. At the beginning of the drying the energy consumption was high on account of the large moisture content and decreased with decreasing moisture content. The exergy for inflow and outflow was observed to be increased with increasing the air temperature used for drying process. Furthermore, it was observed that the lower temperature of the drying air, the lower exergy losses for entire drying period in range of 0-900 minutes.

  • Industrial Automation and Edge Computing SCADA PLC PAC IO-LINK-2

    • Authors: Fatih TOPALOĞLU
      Abstract: Increasing interest in Industry 4.0 applications has brought with it many new technologies and strategies for processing all kinds of production-related data, which are at the center of this trend. Although many of these technologies are not very new, they have not yet reached sufficient recognition in the industry. The term edge computing is among the concepts that need to be clarified in this context. Edge computing draws local intelligence and data processing capability to the parts of the communication network close to the end devices such as pumps, motors, sensors, relays that produce data, and performs the analysis of the data without the need to transfer it somewhere. However, this process also has difficulties. Edge computing architectures in industrial applications need to address bandwidth, management complexity, latency, and network security risks. With this study, four important architectural solutions that help to optimize resource usage on the edge computing platform for industrial applications are proposed and analyzed.

  • Quantum Cryptography, Quantum Communicatıon and Quantum Computing
           Problems and Solutions

    • Authors: Muharrem Tuncay GENÇOĞLU
      Abstract: The development of quantum technologies will open up new perspectives in the use of quantum algorithms, the creation and modeling of complex physical and biological systems, new physical methods of transmitting, receiving and processing information. In turn, this will give impetus to the development of a large number of applications in the scientific, technical, economic and social spheres of society. Quantum cryptography is a communication protection method based on certain phenomena of quantum physics. Unlike traditional cryptography, which uses mathematical methods to ensure the secrecy of information, quantum cryptography focuses on physics, where information is carried using objects of quantum mechanics. The process of sending and receiving is always carried out by physical means, for example using electrons in an electric current, or photons in fiber-optic communication lines. In this process, the current situation was determined and the problems encountered and the solution suggestions for these problems were tried to be addressed.

  • Classification of 40 Different Human Movements with CNN Architectures and
           Comparison of Their Performance

    • Authors: Muhammed YILDIRIM ; Ahmet ÇINAR
      Abstract: Detection of human movements has become one of the current issues with the developing technology. Recognition of human movements is used in many areas such as security systems, human computer interaction, human robot interaction. Due to the increase in data stored in databases, deep learning methods have recently become one of the most frequently used methods. At this study, it is aimed to classify human movements by using Convolutional Neural Network (CNN) architectures. Images are classified with InceptionV3, Googlenet and Alexnet architectures using a data set with 40 different motion classes. The highest accuracy rate with 76.15% was obtained in InceptionV3 architecture. Increasing the amount of data in CNN networks is a parameter that closely concerns the network uptime. Since 40 different motion classes are used in this study, the results obtained in the related architectures are obtained in different times.

  • Classification of Brain Tumor Images using Deep Learning Methods

    • Authors: Harun BİNGOL ; Bilal ALATAS
      Abstract: Big data refer to all of the information and documents in the form of videos, photographs, text, created by gathering from different sources about a subject. Deep learning architectures are often used to reveal hidden information in the big data environment. Brain tumor is a fatal disease that negatively affects human life. Early diagnosis of the disease greatly increases the patient's chance of survival. For this reason, this study was conducted so that doctors could diagnose patients early. In this paper, deep learning architectures Alexnet, Googlenet, and Resnet50 architectures were used to detect brain tumor images. The highest accuracy rate was achieved in the Resnet50 architecture. The accuracy value of 85.71 percent obtained as a result of the experiments will be improved in our future studies. We will try to develop a new method based on convolutional neural networks in the near future. With this model, we will try to achieve higher accuracy than any known deep learning method.

The randomly generated string of numbers is of great importance in achieving solutions close to the global optimum in intuitive multi- objective optimization. Collecting the randomly generated string of numbers in a certain area increases the risk of moving away from the global optimum. Chaotic maps are used to reduce this risk it is not periodic as the variety of numbers produced in chaotic maps is high. For this reason, chaotic maps are used in the random number generation part of optimization algorithms. Chaos-based algorithms have become an important field of study because they are flexible and can escape from local minimums. In this study, the effects of chaotic maps on the new and successful Multipurpose Gold Sine Algorithm (MOGoldSA) were compared with the Multi-Objectıve Ant Lion Optimization (MOALO) algorithm.

      Abstract: Local descriptors are the most effective textural image recognition methods. Local descriptors generally consist of two phases. These are binary feature coding and histogram extraction phases, and they often use the signum function for the binary feature extraction. In this article, new fuzzy-based mathematical kernels are proposed for binary feature encoding in local descriptors. Fuzzy kernels consist of membership degree calculation and coding these membership degrees. In order to calculate membership degrees, four fuzzy sets are utilized. The proposed fuzzy kernels are considered as binary feature-extraction functions, and a novel textural image recognition architecture is created using these fuzzy kernels. These architecture phases are; (1) binary feature coding with fuzzy kernels, (2) calculating lower and upper images, (3) histogram extraction, (4) feature reduction with maximum pooling, (5) classification. In the classification phase, a quadratic kernel-based support vector machine (SVM) classifier is utilized. The presented fuzzy kernels are implemented on the Local Binary Pattern (LBP) and Local Graph Structure (LGS). 16 novel methods are presented using fuzzy kernels for each descriptor. In this article, LBP and LGS are used, and 32 novel fuzzy-based methods are proposed to improve recognition capability. 3 facial images and 3 textural image datasets are used to evaluate the methods' performance. The experimental results clearly illustrate that the fuzzy kernels based LBP and LGS methods have high facial and textural image recognition capability.
