3D Modelling Performance and Usage Area Analysis of Popular UAVs in the Surveying and Mapping Industry

Metehan MARAL

3D realistic models are used in many fields such as engineering, archaeology, and city planning. The most effective technique used to create these models is the photogrammetry technique. The hardware and software features of the unmanned aerial vehicles to be used to implement this technique are of great importance. Many different unmanned aerial vehicles can be used for photogrammetric studies in the surveying and mapping industry, and therefore users have difficulties choosing needed unmanned aerial vehicles for their studies. In this study, 3D modelling performance and usage areas of popula ...Daha fazlası

Mongolia: social and economic issues

Along with the interest in general Turkish history, the interest in the history, language and culture of the Mongols has also increased; researchers who prefer this field as a field of specialization have increased. Especially in recent years, Turkish and Mongolian academics have carried out joint studies, workshops and conferences in the field of history, language and culture, and shared them with the scientific world. This historical interest in the Mongols and the geography of Mongolia has also triggered the interest in the contemporary life, social and economic situation of Mongolia. Izmir ...Daha fazlası

Millions of people worldwide suffer from diabetes and diseases caused by diabetes. As a result of the statistical studies carried out by the World Health Organization (WHO), the number of people suffering from diabetes was 108 million in 1980, then it was increased to 422 million in 2014. Diabetes is increasing rapidly, particularly in underdeveloped and developing countries and it was predicted that 1.5 million people died because of it only in 2019 (WHO, 2021).

Synthesis and Design of Graphene-Based Nanostructure as an Electromagnetic Wave Absorbing Material

Gülperi Feyza YAVUZ

The progress of electronic information technology brings along some problems caused by electromagnetic (EM) waves. For this reason, electromagnetic absorber materials have drawn attention recently for application areas such as electronic, defense stealth technology, and satellite communication systems.

Surface Roughness Performance Related to the Direction in Composite Structures Produced by the Fused Filament Fabrication Method and Improve to Surface Roughness

Özlem DOĞRU

Additive manufacturing is used today in different industries to produce prototypes and even final products. Additive manufacturing offers solutions for the fabrication of complex geometries and is preferred for manufacturing parts in a wide variety of applications. The fused filament fabrication (FFF) method is the additive manufacturing method with the most users worldwide. With the developing material science, it has been possible to produce composite structures and even metal products by going beyond the production of pure polymers in the FFF method. The mechanical properties of the materia ...Daha fazlası

Aging Heat Treatment of Additive Manufacturing Maraging Steels in Nitrogen Containing Atmospheres

Derya Çakan

Additive Manufacturing (AM) is a manufacturing method that pushes the limits of imagination and eliminates the question of whether complex industrial products can be produced that cannot be obtained with traditional manufacturing methods. In this study, microstructure and mechanical properties of maraging steels produced by DMLS method and aged in different durations (6 and 9 hours) and atmospheres (Air, N2 and N2/H2) were investigated. When the SEM images were examined, it was ob-served that the molten pool boundaries did not disappear completely but became blur-red with increasing temperatur ...Daha fazlası

Development of Electromagnetic Wave Absorption Properties of Graphene-Based Nanocomposites by Using Stochastic Optimization Methods

Kemal Bartu Aydın

Today, with the developing telecommunications and electronic technologies for civilian and military purposes, electromagnetic (EM) applications have a wide usage area, including different frequency ranges, such as radar, wireless information transfer, and medical technologies, as well as radio frequencies. However, the broad use of these technologies causes EM wave pollution, so they have a devastating effect not only on the working functionalities of electronic devices but also on human health. Therefore, the need to develop these technologies to prevent EM wave pollution is increasing daily. ...Daha fazlası
