  • Air Pollution Assessment in Turhal District: Temporal Analysis of
           Pollutants

    • Authors: Yeliz DURGUN
      Abstract: Since the last century, the rapidly increasing global population, along with industrialization and urbanization, has increased the type and amount of pollutants in the atmosphere. Particularly, the dependency on fossil fuels for energy production, transportation, and industrial activities has become one of the main sources of air pollution. This has led to an air pollution problem that negatively affects the quality of life in urban areas. However, in this study conducted in the Turhal district of Tokat, an optimistic development has been observed in recent years. Based on the data obtained from the air quality monitoring stations located in the region, the concentrations of pollutants such as PM10, NO2, NOX, and SO2 have been thoroughly examined. The analysis results indicate a significant decreasing trend in the concentrations of these pollutants from 2020 to 2023. This positive trend can be attributed to the increasing awareness of environmental protection, technological innovations, and societal consciousness. The study demonstrates the positive impacts on regional air quality during this period.

  • Determination of High Risks and Elimination of Possible Risks in the
           Winding Section of an Energy Company Using the Fine-Kinney Method

    • Authors: Kübra TÜMAY ATEŞ
      Abstract: In our country, risk assessment and risk analysis have been made mandatory in the workplaces by the relevant regulations of the Law No. 6331. However, despite this, potential hazards cannot be avoided both in industry and workplaces. Predicting what kind of dangers employers and employees may be exposed to in industrial companies is one of the important difficulties encountered. For this reason, it is one of the most important procedures to make a correct risk assessment and to identify, prevent and control Occupational Health and Safety (OHS) risks. One of the many techniques used for OHS risk assessment is the Fine-Kinney model. Most Fine-Kinney-based risk assessment approaches can take into account the relative importance of risk parameters. An improved Fine-Kinney occupational risk assessment approach is proposed in the study. In order to demonstrate the feasibility of the proposed approach, risk values and risk avoidance values have been systematically calculated in all parts of a power plant. A case study was conducted on the bobbin winding unit (Coiling), hazards were identified and measures were presented to eliminate and/or minimize the risk according to the results of the risk analysis.

  • Comparison of Boriding Heat Treatment and Induction Boriding Method

    • Authors: Ulaş İPEKOĞLU; Uğur ÇAVDAR
      Abstract: Induction boriding is a metal processing technique that applies a surface accumulation process using a high-frequency electromagnetic field on metal parts. The adoption of this method in industrial applications is anticipated due to its advantages such as high efficiency, precision, and low energy consumption. Induction boriding relies on the principle of using the electromagnetic field to heat metal parts and create desired properties on the surface. During this process, the high-frequency current produced by induction coils penetrates into the metal part, causing heating due to internal resistance. This heating allows the formation of desired characteristics like surface hardness, durability, or other specific attributes. The boriding process is carried out within the range of 2-8 hours and at temperatures between 850-1000°C. In induction boriding, faster boron diffusion is expected, leading to the anticipation of reaching the desired hardness and coating thickness values in a shorter timeframe.

  • Remote-Controlled Affordable Solenoid Valve Design and a Web-Based
           Approach to Its Implementation

    • Authors: Mahmut DURGUN; Levent GÖKREM
      Abstract: Irrigating agricultural lands remotely using automated irrigation systems can mitigate water and energy wastage, reducing it to a minimum. This study aims to design an agricultural irrigation system that operates by remotely opening and closing solenoid valves. The envisioned solenoid valve comprises a wireless microcontroller, a power circuit, and a basic valve mechanism. The remote and automated irrigation system can monitor and receive commands for the connected solenoid valves through web services and a web interface. After every operation executed by the system, interfaces displaying the real-time status or historical operational states of the controlled solenoid valves are presented to the users. This system is orchestrated using a web server operating on a cloud server, serving as the system control center. Solenoid valves positioned at ten different points are integrated, facilitating real-time and programmable use based on user requests. The system uses a secured website, accessed via user passwords, as a communication interface to receive irrigation control requests. It offers the capability for multiple users to control the system simultaneously through the same interface. Ultimately, this research seeks to establish a secure, remote, and automated irrigation system based on the control and scheduling of low-cost solenoid valves via a web page.

           Current Situation and Future Prospects

    • Authors: Elifcan GÖÇMEN POLAT
      Abstract: Raw materials are the necessary building blocks for the functioning of the country's economy and industries. It is inevitable for countries to direct their economic policies towards sustainability within the scope of their green and digital transformation efforts. The fact that green and digital transformation are among the most driving forces in achieving sustainable development also reveals the criticality of the raw materials to be used in the technologies required for this transformation. The positive effects of raw materials come to the fore in many areas such as the use of carbon neutral and green technologies required for climate and energy targets, the design of sustainable cities, and healthy and quality life. However, it is necessary to discuss the dilemma created by the negative environmental effects of mining activities undertaken to extract the raw materials necessary to achieve sustainability goals. Therefore, in this study, the positive or negative effects of raw materials on the Sustainable Development Goals (SDGs), sustainable performance criteria that can be used in the evaluation of raw materials, are examined with strategic planning tools. Policies, measures, and investments regarding the performance measures achieved in Turkey are investigated. At the end of the study, the strengths, weaknesses, threats, and opportunities of some raw materials in terms of targets are evaluated. Additionally, through analysis of critical success factors, numerical inputs that can be used for researchers conducting data studies in this field are presented.

  • Prediction of Chicken Diseases by Transfer Learning Method

    • Authors: Mustafa Can BINGOL; Gürkan BİLGİN
      Abstract: With the development of computing technologies, artificial intelligence is used in a wide range of areas, from engineering to healthcare. In this study, it was aimed to predict chicken diseases with transfer learning. For this purpose, a ready-made data set was studied. This data set contains fecal photographs of healthy chickens diagnosed with Coccidiosis, Newcastle and Salmonella diseases. The data set has been subjected to necessary pre-processing such as size readjustment. Subsequently, the data set, which was then subjected to pre-processing, was divided into 70% and 30% as training and testing. To solve the disease classification problem, a network was created by adding fully connected layers to ResNet50, InceptionV3, InceptionResNetV2, Xception and MobileNetV2 architectures. The weights of the architectures mentioned in these networks were selected as ImageNet and were not trained. Then, networks containing these architectures were trained using the training data set. The trained networks were validated with the test data set and accuracy rates of 32.7%, 80.6%, 85.2%, 89.2% and 90.7% were obtained, respectively. According to these results, MobileNetV2 was used in the proposed artificial neural network architecture since the best result was calculated using the MobileNetV2 architecture. The proposed artificial neural network architecture was trained with the same training set and validation was carried out with the same test data set. After these procedures, the true prediction rate of the proposed architecture for the test data set was calculated as 92.1%. Also, F1 score of the proposed architecture was measured 0.923. Additionally, thanks to the deconvolution layer used in the proposed architecture, network sizes have been reduced by approximately 50%. Thanks to this reduction, the training time is shortened and it becomes easier to implement it on embedded systems in future studies. As a result, the diseases of chickens were predicted largely accurately with the transfer learning method.

  • Lossless Grounded Capacitance Multiplier Based On Two CFOAs

    • Authors: Tolga YÜCEHAN
      Abstract: A new lossless grounded capacitance multiplier (GCM) based on two current-feedback operational amplifiers (CFOAs) is proposed. The proposed circuit is built with a least number of passive elements. The capacitor is selected as grounded in the proposed circuit, while one resistor is grounded and the other is floating. The proposed GCM has low power consumption and a very large multiplying factor. The passive element matching conditions are not necessary for the designed GCM. The SPICE program is used for the simulations, and all the simulations are performed with 0.18µm CMOS technology parameters. The simulation results verify the ideal results from 10Hz to 15MHz. Further, the designed GCM is tested in the application circuit, which is a second-order passive filter. The experiments of the desgined GCM are achieved by using AD844s instead of CFOAs.

           Models

    • Authors: Emre AVUÇLU
      Abstract: The value of the economy provided by pistachios to the countries where they are grown is increasing day by day. From this point of view, the importance of correct classification of pistachios is known. The more accurately the harvested pistachios are classified, the better the monetary return value. In this study, two different classes of pistachios were classified using VGG16 and VGG19 deep learning architectures. There are 2148 pieces of Kirmizi and Siirt Pistachio in the dataset. Experimental studies were carried out with 5-fold crossvalidation. As a result of the experimental studies, the Accuracy value of 0.802117 and the F1-measure value of 0.830593 were obtained from the average of 5 folds from the VGG16 deep learning model. Likewise, the Accuracy value of 0.779404 and the F-measure value as 0.779404 were obtained from the average of 5 folds from the VGG19 deep learning model.

  • Examining The Effect of Pre-processed Covid-19 Images On Classification
           Performance Using Deep Learning Method

    • Authors: Emre AVUÇLU
      Abstract: In recent years, researchers have been using different artificial intelligence models to process x-ray images and make a determination about the patient's condition. Pre-processing is applied to medical images by many researchers. In this way, researchers know that the results they will obtain will be better and that their study results will be more accepted in the literature. As with all other medical images, pre-processing of Covid-19 images is generally done to obtain better classification results. In this study, some pre-processing was done with Covid-19 images. Experimental studies were performed using the ResNet18 deep learning model. According to experimental studies carried out on non pre-processed images, an average accuracy of 0.85206% was obtained in the test processes, while an accuracy rate of 0.93086% was obtained in the test processes obtained from pre-processed images. It was observed that better results were obtained by processing pre-processed images with the same model.

  • Estimation of Young's Modulus of Limestones using Multi-Layer
           Perceptron

    • Authors: Ebru EFEOĞLU
      Abstract: The Young’s modulus (E) is a very important parameter used in many engineering projects and in the petroleum industry. It is especially important for tunneling, mining and rock slope stability analysis. This parameter is determined by difficult experiments. In addition, cores must be taken for the experiment and the cores taken must be of high quality. The aim of the study is to estimate the Young’s modulus, which represents the basic mechanical property of rocks, using relatively easy-to-apply and low-cost methods. For this purpose, the multi-layer perception method was used. Input parameters of these meshes are Dry density, Water saturated density, Bulk density, Porosity, Water absorption, Ultrasound Pulse Velocity (UPV), Poisson ratio (v), Tensile strength (To), The uniaxial compressive strength (UCS) and The point load index (Is)' is Four different network models were created and the successes of these network models were compared using the 5-fold cross-validation method. As a result of the comparison, it was understood that the model 2 network was more successful. The Correlation coefficient values of the model were calculated as 95% in training and 84% in 5-fold cross validation.

  • Crystal Structure of Zwitterionic
           (E)-9-(((3-hydroxyphenyl)iminio)methyl)-1,2,3,5,6,7-
           Hexahydropyrido[3,2,1-ij]Quinolin-8-Olate

    • Authors: Hasan İNAÇ
      Abstract: The title compound (1), C19H20N2O2, crystallized with single molecule in the asymmetric unit and is present in the zwitterionic form. The compound was synthesized from the condensation reaction of 8-hydroxyjulolidine-9-carbaldehyde and 3-aminophenol. In solid state compound adopts the keto–amine tautomeric form, with the H atom attached to the N atom, which participates in an intramolecular N—H···O hydrogen bond with an S(6) ring motif. The conformation about the C=N bond is E. The aromatic ring of the julolidine moiety is inclined to the phenol ring by 13.00 (10)°. The fused non-aromatic rings of the julolidine moiety adopts a screw-boat conformations. In the crystal, the molecules are connected by N—H···O and O—H···O hydrogen bonds, with adjacent molecules related by a 21 screw axis, generating– A–B–A–B–zigzag chains extending along [010]. Furthermore, adjacent molecules are linked by pairs of C—H···O interactions, forming a ladder-like structure propagating along the a-axis direction. Density functional theory (DFT) optimized structures at the B3LYP/6–311 G(d,p) level is compared with the experimentally determined molecular structure in the solid state.
