An important part of UAV technological development consists of improvements in the scope of path planning. Different choices can be made in path planning according to operational priorities, it may be preferred to reach the destination as fast as possible or to increase the airtime by compromising speed. For every speed and altitude that the UAV can fly; fuel data of cruise, climb and descent phases are used in the path planning algorithm. Thus, economical and airtime-maximizing paths could be produced on the basis of performance characteristics compatible with the kinematic constraints customized for the UAV. In this study, Cellular (cGA) and Segmented Cellular Genetic Algorithm (scGA) are proposed. The novel overprotective algorithm which has a fixed initial population and segmented chromosome structure achieves a high convergence speed to optimal solution and can generate paths which have 5.2 times higher fitness value on average compared with a conventional Genetic Algorithm (GA). It has been seen that scGA improves the initial population in terms of the best solutions 1.9 times and the general population 5.8 times better compared with GA. [ABSTRACT FROM AUTHOR]

İnsansız hava araçlarının dünya genelinde birçok kullanım alanı mevcuttur. Multidisipliner alanda kullanılan bu araçlar Türkiye Cumhuriyeti’nin terörle mücadele sürecinde taktiksel değişimi beraberinde getirmiş ve Millî Teknoloji Hamlesi kapsamında Türkiye’nin uluslararası güvenliğe katkısı açısından büyük öneme sahip olmuştur. IHA/SIHA üretimi sürecinde bu konuda çığır açan çalışmalar resmî kurumlar ve BAYKAR gibi şahsi girişimler tarafından geliştirilmiş ve Türkiye’nin liderlik ettiği sınır ötesi operasyonlarda önemli başarılar kat edilmiş ve bölgesel güvenliğin sağlanmasında Türkiye önemli bir rol oynamıştır. 1990’lardan bu yana yurtdışı bağımlılık neticesinde satın alınan cihaz ve silahların veri güvenliği sağlanamadığından ülke kendi savunma sanayi stratejisini oluşturmuş ve başarılı bir istihbarı temel ile havadan havaya füze atma kapasiteli son teknoloji savaş uçakları ve insansız hava araçları ile yapılan operasyonlar başta DAEŞ olmak üzere terör örgütlerinin hareket kabiliyetlerini önemli ölçüde kısıtlamış ve Türkiye’yi bölgesel ve uluslararası güvenlik alanında önemli bir oyuncu hâline getirmiştir. Ülkelerin bağımsızlığının sadece özgürlük ve demokrasi yönetimi ile sınırlandırılamayacağı günümüzde bir ülkenin kendi güvenliği için özellikle savunma sanayisinde yenilikler yapıp ilerleme kaydedebilmesi gerekmektedir. Türkiye’nin son yıllarda önemli bir ivme kazandığı insansız hava aracı sistemleri hem devlet güvenliği hem de bölgesel ve uluslararası güvenlik hususlarında ülkenin yeni bir rol elde etmesini sağlamıştır. Bir başka deyişle bu araçlar geleneksel askeri hava araçlarına kıyasla maliyet etkinliği ve riskin az olması gibi avantajlara sahip olup ayrıca Türkiye’nin IHA/SIHA’larını kendi iç güvenlik operasyonlarında ve sınır güvenliği gibi alanlarda kullanması bu teknolojinin stratejik önemini artırmıştır. Türkiye’nin bu alandaki ilerlemesi, uluslararası güvenlik politikaları ve savunma sanayisi trendleri açısından da önemli bir gelişme olarak değerlendirilebilir. Bu teknolojik gelişmelerin, Türkiye’nin dış politika ve savunma stratejilerini nasıl etkilediği konusunda detaylı bir analiz yapmak, bu konunun karmaşıklığını daha iyi anlamamıza yardımcı olabilir.

In this study, motion of a quadcopter (that is called DRIHA) to track a target is auto controlled based on the data acquired by images. The images are taken by the monocular camera mounted on the center of gravity of the DRIHA. The detected target is automatically tracked by proposed methods. Designed controllers control translational and rotational motion with respect to the motion occurred in images. An image error vector is proposed to reduce the effects of error signals on the motion. Controllers are designed for controlling the pitch, roll, and yaw angles using the features in the image plane. The model developed by the image-based visual servoing (IBVS) approach is tested in the Gazebo simulation environment. Simulation test results validate effectiveness of the proposed system that includes simultaneous and comprehensive designs in terms of automatic control and target tracking performance. The proposed methods enable autonomous navigation applications even in environments where global positioning systems are unavailable. [ABSTRACT FROM AUTHOR]

In this study, a bibliometric analysis of scientific publications on Unmanned Combat Aerial Vehicles was conducted within the framework of the Web of Science Database Core Collection. As a result of the analysis, it has been observed that although there has been an increasing trend in the last 10 years, especially in research-oriented publications, there are still not enough high-level indexed studies, especially review-oriented studies. In addition, the rate of international authorship in the studies is very low, and studies are generally multi-authored and conducted at national level. Almost all of the studies are focused on technical and engineering disciplines, and the level of interdisciplinary work with social sciences is still very insufficient. The findings of both the overall performance analysis and the bibliometric analysis show that in terms of authors, publications, citations, institutions and countries, first China and then the USA are by far in the leading position in academic studies compared to other countries.

Advanced camera systems integrated in to unmanned aerial vehicles (UAVs) enable the acquisition of highresolution images. These images are often more advantageous in terms of spatial, temporal, radiometric, and spectral resolution compared to satellite images. However, depending on the size of the scanned areas, the acquired data becomes large and occupies significant storage space. Therefore, processing the data to obtain meaningful information and insights becomes challenging. Various methods have been developed to extract meaningful data from images. While operators used to analyze images one by one in the past, today, objectbased and pixel-based data extractions have been developed. Thanks to these methods, data can be parsed by software rapidly and with high accuracy. Segmentation and classification methods facilitate processes such as categorization, sub-classification, parsing, and detection. Segmentation and classification processes on data are of crucial importance for the analysis of large and complex datasets. Numerous studies demonstrate that these techniques and applications are continuously evolving and gaining prominence in the literature. Within the scope of this study, segmentation and classification efforts conducted with UAVs have been discussed, and the outcomes of these studies have been examined. It is observed that studies utilizing hybrid and deep learning-based techniques tend to yield more efficient results compared to other approaches. [ABSTRACT FROM AUTHOR]

Mining and mining activities are among the sectors that make a major contribution to the national economy. Fast and accurate production planning for the work to be carried out in the mine makes an important contribution. For this purpose, it is necessary to map the mine sites and measure their volumes. UAVs, which have been used in various fields as the technology has developed, have found a place in the mining sector for various purposes. UAVs are much cheaper and more practical to use compared to other expensive technologies, especially for measurements in mining areas. In this study, a digital elevation model and an orthomosaic map were produced from the data collected by the UAV. Using the digital maps produced, a state-of-the-art map of the mine site was made and finally the volume calculation of the 2 waste areas in the mine site was performed in two different software. As a result, it was observed that the use of UAV technology in the mining sector, especially in open pit mines, is an effective method and offers significant advantages over conventional methods. It was also found that the volume calculations made using UAV technology are highly accurate and highly consistent with the results obtained using conventional methods. [ABSTRACT FROM AUTHOR]

Maps produced using remote sensing (RS) and photogrammetry techniques are commonly used today. Alongside rapidly advancing technology, RS, photogrammetric sensors, and transportation platforms are changing and evolving. Particularly, the advancement in unmanned aerial vehicle (UAV) technology has facilitated access to aerial images. Besides being faster compared to other methods, the inclusion of spatial information makes UAV imagery advantageous. The increasing urban population and the expansion, renewal, and growth of cities have heightened the need for rapidly and accurately collected spatial data. UAV usage is one of the methods in accessing the required raw data. 3D building models, being a crucial component of 3D virtual city models, play an important role in detecting existing buildings through digital products produced via photogrammetric methods from UAV-obtained aerial imagery. Considering that our country is prone to earthquakes, there is a significant need for 3D virtual models of our cities. The possible creation of a 3D virtual city model enables the determination of material damage post-earthquake and facilitates access to information about the residents in the area. In this study, the New Neighborhood district of Şefaatli, Yozgat, was selected as the application area. As a result of the study, a 3D virtual model of the neighborhood located in the stream bed was created. The 3D virtual model has successfully achieved its purpose by carrying information in addition to the 3D appearance of the buildings in the attribute data. [ABSTRACT FROM AUTHOR]

In this study, the speed control of a Cessna 172 aircraft is carried out under windy weather conditions by combining X-Plane, which is a computer-based flight simulator, with Simulink. Model predictive controller (MPC) is developed for the model linearized under trim conditions and software-in-the-loop (SIL) tests are performed. Von Karman wind turbulence model, which is widely preferred in the literature as a wind disturbance effect, is added to the model. Data communication is provided through a realtime user datagram protocol (UDP). The results of simulation studies are examined by comparing those of PID control-based autopilot development studies in the literature. Accordingly, in the UAV controlled by the MPC method, which also takes into account flight control surfaces and throttle constraints, the speed reference changes are accurately monitored while maintaining pitch stability, and it is observed that more successful virtual flight tests are carried out compared to the similar studies.

In this study, the performance of cooperative transmission medium access control (CT-MAC) protocol for unmanned aerial vehicles (UAV) on Nakagami-m channel fading is investigated. The proposed protocol mainly includes direct transmission (DT) and cooperative transmission (CT) modes to increase throughput. Besides, the algorithm is defined to select a suitable data transmission mode and select the optimal relay. The mechanism defined in the IEEE 802.11 standards specifically designed for direct communication is not suitable for cooperative communication. Therefore, new control packets are used and the existing control packet format has been changed to support cooperative communication. To perform the performance analysis of the proposed CT-MAC protocol, an analytical model based on the unsaturated Markov Chain model is derived and validated by simulation. The simulation results show that the proposed protocol maximizes system efficiency. [ABSTRACT FROM AUTHOR]

Remote sensing data and techniques are widely used in modern forestry studies. Today, aerial photographs taken with remote sensors on Unmanned Aerial Vehicles (UAV) can be processed by using softcopy photogrammetry to produce data such as point cloud and orthomosaic. Therefore, it is possible to make some remote measurements in forest ecosystems. It may be necessary to predict stem volumes of trees cut down in a forest area or felled for any reason in a practical way. In this study, it is aimed to predict the over-bark stem volumes by measuring the diameter and height of cut brutian pine trees (Pinus brutia Ten.) in orthomosaic and point cloud data produced from UAV photographs. The study was carried out in 2 different brutian pine stands located within the borders of Çandır Forestry Chief of Sütçüler Forestry Directorate in Isparta Regional Directorate of Forestry. In these areas, the diameter at breast height (d1.3) and total height of 175 cut brutian pine trees were measured on the point cloud and orthomosaics, tree volume predictions were made from these values obtained by various methods and the results were compared with the references data based on field measurements. In the study, the diameter and height measurement results calculated depending on the ground sampling distance of the aerial photographs were also compared. According to the findings, the lowest correlation value of 0.78 and the highest 0.92 for diameter measurements, the lowest 0.96 and highest 0.99 correlation values in height measurements, the lowest 0.70 and the highest 0.93 correlation values in stem volume predictions were obtained between UAV photogrammetry and reference data. As a result, it has been understood that UAVs, which are preferred as a practical remote sensing tool today, can be used to measure the diameter and height of pine trees lying on the ground and stem volumes can be successfully predicted by UAV photogrammetry.

This study evaluates, the mass movement that occurred after heavy rains on January 8, 2020 in the Kargıcak district between Km 31+300 and 31+500 of the D-715 highway connecting Silifke and Mut districts. For this purpose, a 2 cm resolution digital surface model and an engineering geological map were first made, using photogrammetric methods from the photographs taken by the unmanned aerial vehicle (UAV). The index and geomechanical parameters of the units were determined by taking disturbed and undisturbed samples obtained from nine boreholes in the area where the landslide occurred. The depth of the sliding surface and velocity of movement were determined using the data acquired from the inclinometers placed on the boreholes. The heavy rains that occurred in the region before January 8, 2020 increased the pore water pressure in the weathered claystone-clay unit outcropping in the landslide area, which in turn caused a decrease in the shear strength of the unit. The Kargicak Landslide started rotationally and developed planarly on the claystone-marl surface with the weathered claystone-clay unit. [ABSTRACT FROM AUTHOR]

The present study was conducted to determine the areas and volumes of erosion zones in Thrace peninsula using geographical information systems (GIS). Measurements made with remote sensing both save time and prevent excess workforce. In addition, it is less costly than satellite images that can be purchased for areas where drones can be shot. For this purpose, 13 erosion sites with different environmental characteristics were examined and images were obtained with an unmanned aerial vehicle (UAV) in the study area. To calibrate the UAV data, the boundaries were determined using nature-friendly white paint. Then, all measurements (lengths, angles, etc.) of these areas were calculated from various altitudes. Volume of the determined areas then processed using GIS software and a graphic program named "Autodesk Inventor". All of the UAV tasks were taken under suitable weather condition in order to avoid any difference in the images. Furher, the UAV images to be combined were obtained under similar weather conditions to ensure that factors such as light and shadow do not cause any deviation in the calculations and create visual differences. Images were taken from a total of 13 erosion areas and WGS 1984 (World Geodetic System 1984) was used as the coordinate system in the present study. Orthomosaic images of these areas were created by combining the images. In addition to the areas and volumes of the regions in the images, calibration analyzes were also made. Using a small area for calibration in the study increased the accuracy of area measurement rate above 90%, while this rate was found between 60 - 78% in volume measurement depending on the flight altitude. 12 photos were used in the image taken from a height of 100 meters and 103 from a height of 10 meters in the calibration from approximately 100 m². Accordingly, the volumetric accuracy rate was found to be 78.57% in the image taken from a height of 10 meters from the ground. [ABSTRACT FROM AUTHOR]

Batteries, which are an essential part of electronic systems, play an important role as a power source. Today, rechargeable batteries are used in many areas, such as mobile vehicles, electronic devices, and backup power. Monitoring the batteries during the charging or discharging process ensures the protection and safety of the battery life in terms of performance. Battery Management Systems (BMS) ensure that the balance in the cells is maintained by charging or discharging the cells of the battery in a balanced way. These systems provide the ability to extend the life and optimize of the batteries. In this study, a system has been developed that will allow the monitoring of Lithium Polymer (LiPo) batteries used in Unmanned Aerial Vehicles (UAV) during the charging process. With the developed system, the voltage values of the LiPo battery cells are monitored in real time with an interface. [ABSTRACT FROM AUTHOR]
