This study evaluates the performance of Faster R-CNN and YOLOv7 object detectors for dynamic ship detection in maritime applications. Both algorithms are tested under challenging conditions, including poor image quality due to cloud and dust obscuration, varyi…

Cellular phones are playing an important role in technological devices in today’s world. People start to use cellular phones at early ages. Even kids have their own cellular phones as a precaution for their security. However, researches evaluating long term …

Diabetic retinopathy is the leading cause of blindness among diabetic patients. It occurs when the light-sensitive tissue in the retina is damaged. According to WHO statistics, the current global prevalence of diabetic retinopathy is approximately 103 million …

Bu çalışmada, Dünya’nın önde gelen kadın politikacılarının liderlik tarzları, liderlik kuramları çerçevesinde analiz edilecektir. Bu kapsamda, Indra Gandi, Margareth Thatcher, Angela Merkel, Benazir Butto ve diğer kadın politikacılarının liderlik davranışları,…

High temperature superconductors (HTSs) have been widely used in magnetic bearing systems, magnetically levitated transportation systems (Maglev), superconducting motors, etc. due to their stable levitation properties. Although the studies on Maglev systems ha…

In the present study, energy and exergy analyses of a solar powered absorption refrigeration system are corried out by terms of the first and second laws of thermodynamics. NH3-H2O fluid couple is used in the system. The analyses are performed with the help of…

The use of neon indictor lamp glow discharge detectors (GDDs) has a relatively great potential for a number of microwave detecting and imaging applications. This is so because of their many advantages which include but not limited to; low cost, fast response t…

Although numerous amounts of research have been done to find alternate sources of energy consumption and its applications. But in times of energy crisis and global warming urgency, it is needed to pace towards methods of less dependency on fossil fuels in the …

Pink noise, which has a power spectral density that is inversely proportional to the frequency, is widely used for acoustic applications such as for testing audio equipment. Its generation from white noise requires such a system transfer function that it is no…

Yeni teknolojiler ve makineleşme, 20. yüzyılın başlarında İtalya’da ortaya çıkan Fütürizm akımıyla birlikte insanlığın topluma ve onun yaşam alanı olan yapılı çevreye dair öngörülerinin ayrılmaz bir parçası haline gelmiştir. Geçtiğimiz yüzyılda bilim ve teknol…

Using a lens to concentrate sunlight and focus it on smaller sized solar cells increases the system’s output power and in the same time decreases the cost by replacing much of the expensive semiconductor photovoltaic cells with the cheaper optics. But the conc…

Energy conversion systems are very diverse. One of the most important of these systems is undoubtedly the electric machines. Mechanical energy production from electricity has been ongoing for about 150 years. With rapid developing technology, it has shown a ra…

Developing technology, and electronic devices, power consumption is increasing day by day. At the present time, there are many methods used to generate electricity. Most of these methods cause environmental pollution. The share of thermal power plants in elect…

The integration of increasing renewable energy-based energy production into the existing electricity grid has become of great importance. The biggest difficulty to integration into the power grid is variability and discontinuity of wind energy. To deal with th…

This study examines the effects of inrush current loads on electric motors operating under low-temperature conditions. While electric motors have a wide range of applications in industrial and military environments, they face significant performance challenges…

Oscillators are one of the most important basic circuit blocks frequently used in electrical-electronics engineering applications. Among several types of the sinusoidal oscillators, quadrature oscillators are frequently used in communication circuits, control …

This study was carried out in the pure oriental beech forests of Yenice-Kızılkay in the Western Black Sea Region of Turkey, where the changes in the number of side roots and the changes in the height and diameter of the beech trees were examined in three diffe…

Bu çalışma, en ilkel omurgalı canlılardan biri olan taşemen balığının yüzme deseninin oluşturulması amacıyla, bir sinüzoidal osilatör ve birkaç birinci dereceden alçak geçiren filtre ile oluşturulan basit bir merkezi desen üreteci (Central Pattern Generator-CP…

In this work, the effects of bis (2-methoxy-4-allylphenyl) oxalate (I) on levitation (Fz) and lateral forces (Fx) of bulk MgB2 superconductor has been investigated and reported for the first time. All samples were prepared from magnesium powder (Mg, 99.8 %),…

This study presents a comparative evaluation of five widely adopted blockchain consensus algorithms—Proof of Work (PoW), Proof of Stake (PoS), Delegated Proof of Stake (DPoS), Practical Byzantine Fault Tolerance (PBFT), and Proof of Authority (PoA)—based on en…
