Recently, the basis properties and eigenfunction expansions in various function spaces of the eigenfunction of the regular boundary value problems with spectral parameter in the boundary conditions have been investigated by many mathematicans. However in diff…

The term structural optimization is commonly used for the optimization of engineering structures, such as building, automobile, or airplane structures for improved strength, stiffness properties, fatigue life and reduced weight or cost. Main purpose of this st…

The developments in internal combustion spark ignition (gasoline) engine technologies are in line with emission standards. The conversion systems which enable the use of LPG fuel in spark ignition (gasoline) engines renew themselves according to the developmen…

The U-shaped assembly line balancing (UALB) problem has been extensively investigated in the existing academic literature. However, only a limited number of studies consider the uncertainty in the assembly lines. In this research, a robust formulation is devel…

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…

Accurate and efficient detection of aircraft at airports is crucial for enhancing airport security, ensuring safe operations, and improving overall air traffic management. As airports grow in complexity and traffic density increases, automated object detection…

Evolution of EU road transport emission standards indicates that the limits have been reduced more than 90% in the last decades. However, nowadays, the urban populations in many developed countries are still suffering from urban transport sourced emissions. On…

In this study, the experimental application of polymer electrolyte membrane fuel cell (PEM-FC) with dc-dc boost converter is realized for compact design of electric vehicle (eV). The PEM-FC is an electro-chemical device which combines hydrogen with oxygen to p…

Drone ya da İnsansız Hava Araçları (İHA), günümüzde birçok farklı sektör tarafından aktif şekilde kullanılmaktadır. Özellikle son yıllarda popülerlik kazanmayı başaran drone'lar; reklamcılıktan kargo taşımacılığına kadar çeşitli görevler üstlenebilmektedir. İH…

Kablosuz ağlar, veri sinyallerinin havadan iletildiği, kablo kullanmadan uzak mesafeler arasında iletişimi sağlayabilen teknolojilerdir. Kablosuz ağlarda veri, radyo frekansları veya kızılötesi ışınlar vasıtasıyla iletilir. Bu ağlardaki kullanıcılar arasında h…

Robot algorithms require faster and more efficient computing due to increasing integration of robot arms to automation systems and expanding capabilities of robotic systems. Inverse kinematics calculations used in trajectory generation is one of these algorith…

Diesel engines have been preferable engines for heavy, medium and light duty vehicle applications due to their superior performance and fuel economy. However, concerns with their emissions, which are highly toxic air pollutants, put some limitations to their w…

Exhaust gas distribution in street canyons is one of the important research subjects in urban air quality studies. Vehicle emissions are an important group of pollutants in urban areas. In this study, the dispersion of exhaust emissions from vehicles in canyon…

In this study, the energy spectrum and wave functions of the hydrogen atom are discussed using the path integral method in complex space. The Path integral is easily applied to the harmonic oscillator problem. The problem of hydrogen atom is transformed into…

Nowadays, there are old and new methods that involve the difficult problems and solution suggestions which many researchers research and try to solve. In the field of engineering, the success rates of the methods that produce solutions to these problems are of…

This study employs a supervised learning approach for the Stock Portfolio Selection (SPS) problem. The proposed approach solves three problems defined in the literature review: the narrow period selection problem, the proper objective selection problem, and th…

Oscillation theory for the solutions of Sturm-Liouville problems is one of the traditional trends in the qualitative theory of difierential equations. Its main goal is to establish su–cient conditions for the existence of oscillating solutions, to investigate…

In this paper, three different types of coordinate transformations that are frequently used in geodetic applications are given the details of their application with evolutionary algorithms. Similarity (Helmert), Affin and Projective transformation models commo…

In the case of developing countries, the need for housing has not been a problem in large measure. Because developing societies are to head towards cities. The unplanned growth and unhealthy settlements conditions because of population generated by this orie…

Urban public spaces which have a place in urban design projects with different scales and degrees, are important living/living parts of the city used by everyone. These places are primarily used for mobility and access but also for official social events. In…
