- Performing Distance Measurements Of Fixed Objects Detected With Yolo Using
Web Camera
Authors: Volkan Karaca; Ebubekir Yaşar
Abstract: Today, cameras are used for many purposes such as image analysis and synthesis. Technological developments have also made the use of image processing techniques more widespread and distance measurements with cameras have become more precise. In addition, examinations show that the cameras are also used to determine precise target distance or depth mapping studies. In this study, using the Yolo v8 model with a single web camera, the doors in a closed area whose positions did not change were detected, and then the distance of the detected object to the camera was tried to be measured. A comparison was made between the actual distances of the camera to the detected object and the measured distances. For distance measurement, measurement was carried out with the Euclidean method using OpenCV libraries. The study was carried out to show how effectively web cameras can be used at short distances and how much deviation occurs in the measurements. It is thought that measurement errors will be minimized using a webcam in future studies.

- A Research on Determining the Importance Levels of Criteria Effective in
Forest Road Network Planning through GIS-Based Methods
Authors: Ersin Dursun
Abstract: This study investigated the importance levels of criteria effective in forest road network planning using Geopraphic Information System (GIS)- based Multi- Criteria Evaluation (MCE) method. It is crucial to determine the criteria to be considered in forest road construction and planning for a standardized application nationwide. The research was conducted within the boundaries of the Yaylacık Forest Management Directorate (YFMD) under the Tokat Forest Management. Firstly, the existing road network was identified in the research. After the identification of the existing road network, a GIS database was created. In this study, criteria to be used, in Forest Road Network Planning (terrain slope, aspect, road density, distance to road, land use, distance to main stream) were determined. Each criterion was classified and scored internally. Information from road and road network planning studies and previous works were utilized in determining the criteria to be used in Forest Road Network Planning. Five different degrees and suitability values are defined for the determined criteria. In this context, it was created to reach 5 fundamental road network planning functions to determine their positional statuses as Absence (Ab), Very Suitable Areas for road planning (VS), Suitable Areas for road planning (S), Less Suitable Areas for road planning (LS), and Very Less Suitable Areas for road planning (VLS). As a result, Terrain Slope and Road Density were determined as the most effective criteria in Road Network Planning, while Distance to Main Stream was identified as the least effective criterion. As a result of the study, a flow chart was created to determine the criteria and impact values that are effective in forest road network planning in order to ensure integrity and convenience in application throughout the country.

- Comparative Analysis of Diabetes Diagnosis with Machine Learning Methods
Authors: Tuğba Aktaş; İsmail Mert Temel, Ahmet Saygılı
Abstract: Diabetes is a disease that occurs when the body cannot regulate the level of sugar (glucose) in the blood. Early diagnosis of this disease is important in preventing more serious diseases that may arise later. Within the scope of this study, an attempt was made to optimize the diabetes data set for use by training it with different models. At the very beginning of the study, Logistic Regression, KNN, SVM (Support Vector Machine), CART (Classification and Regression Trees), RF (Random Forest), Adaboost, GBM (Gradient Boosting Machines), XGBoost (Extreme Gradient Boosting), LGBM (Light Gradient Boosting). Machine), CatBoost models were used. According to the results of the models, RF, LGBM, XGBoost accuracy, and f1 values were observed as the best models, respectively. As a result, in the Random Forest model, which produced the most successful results, Accuracy: 0.88, F1 Score: 0.84, and ROC AUC: 0.95 values were obtained, respectively.

- Monte Carlo Increased-Radius Floating Random Walk Solution For Potential
Problems
Authors: Ali İhsan Çanakoğlu
Abstract: In this paper, a new Monte Carlo walk method is introduced. The increased radius floating random walk combines of the two classical Monte Carlo methods and derived from fixed-radius floating walk method. In this paper, the method is used to solve typical Laplace’s equations in rectangular region. Also, this method is easily applied to Poisson equations. Lower walk number and hence lower computation time are obtained from new method compared with the fixed random walk, floating random walk and fixed-radius random walk methods. Analyzes were performed on an average computer and the solution time was reduced by 80%. The results are also compared with Finite Element Method. Increased radius walk method’s results are good agreement with other methods.

- Modeling the Behavior of Chlorella Vulgaris Microalgae in Water Treatment:
A Kinetic Approach
Authors: Burcu Şimşek Uygun; Serdar Göncü, Esin Buğdaycı
Abstract: In the modern era, there has been a notable surge in environmental pollution attributable to agricultural activities, urban expansion, industrialization, and various other contributing factors. This alarming trend has also taken a toll on our water resources, exacerbated further by the contamination stemming from human consumption-related wastewater discharges. To address these concerns, biological treatment approaches have gained widespread acceptance for wastewater treatment. The utilization of microalgae as a nutrient source, facilitating the removal of organic matter from wastewater, holds a pivotal role in bolstering the sustainability of wastewater treatment. The aim of this study, to mathematically model the removal of phosphorus and nitrogen from domestic wastewater using Chlorella Vulgaris algal culture. Experimental studies were conducted in a batch reactor, and removal efficiencies of nitrate nitrogen, ammonium nitrogen, and phosphate phosphorus were examined through measurements. The results indicate that microalgae efficiently perform the removal of pollutants process. As well as usage of microalgae in water treatment processes, a good microalgae kinetic model is highly important for nutrient removal, microalgae biomass accumulation, and enhancing operational settings in wastewater treatment. Kinetic modeling is a mathematical approach used to understand how a chemical reaction or process progresses or changes over time. Such models have various applications in all fields of science. Kinetic modeling can help us predict and optimize the behavior of reactions using computer simulations and mathematical analysis. Furthermore, specific growth rates of microalgae according to nitrogen and phosphorus nutrients were compared using the Michaelis-Menten equation for growth kinetics. According to the calculations, the nitrogen-based specific growth rate (NO3--N, NH4+-N) was determined as µmax=0.053 day-1, and the phosphorus-based (PO43-) specific growth rate was determined as µmax=0.061 day-1.
