Dünyadaki ve Türkiye’deki teknolojik gelişmelere ve nüfus artışına bağlı olarak elektrik enerji tüketimi artmıştır. Bu artan enerji talebini karşılayabilmek için dünyadaki fosil tabanlı kaynakların yakın gelecekte tükeneceği ve çevreye verdiği zararlardan do…
A novel continues plasma reactor with rotating electrodes was designed and constructed to investigate methane decomposition to hydrogen and solid carbon. This new reactor structure causes stable operation. Hydrogen is main part of gaseous products which cont…
Image processing methods have been widely used for detection of product faults in recent years. Images of industrial products that made of various materials are taken with different types of cameras and by using different lenses. Working on images of metallic …
Today, it is possible to access a lot of information by using medical imaging data (CT and MR). In recent years, CT and MR data have been processed and transferred to computer aided design (CAD) programs. In fact, these solid models modified in the CAD environ…
About 90% of world trade in transportation of goods is conducted via maritime transportation. An important operation area of maritime cargo transportation is ports. It is necessary to keep these ports secure where information and communication technologies a…
Lgbt bireylerin diğer bireylerden farklı olan bir sağlık gereksinimleri yoktur. Sağlık hizmetlerinden etkin şekilde yararlanan LGBT bireyler olmasına rağmen birçoğu cinsel yönelimi ya da cinsiyet kimliği yüzünden yaşadığı stigma, sosyal izolasyon, şiddet ve …
Enerjiye olan talep her geçen gün artmaktadır. Kömür, doğalgaz, petrol gibi birçok farklı geleneksel kaynaklardan bu talep karşılanırken artık günümüzde yeni nesil enerji kaynaklarından olan güneş enerji sistemleri ön plana çıkmıştır. Enerji üretiminde kulla…
Yeşil binalar, binaların çevre ve insan sağlığına etkilerini dikkate alan ileri teknoloji taşınmazlardır. Yeşil binalar, yenilenebilir enerji kaynaklarını kullanarak atık suların kullanılmasını sağlayan, gün ışığından faydalanan, etkin ısı yalıtımı olan ve b…
Denetim, yönetimin amaçları doğrultusunda planlanan ve yapılması beklenen işlemlerin yapılma sürecinin kontrol edilmesi, yapılmış olan faaliyetlerin ne ölçüde hatasız, etkili ve verimli gerçekleştiğini; yapılmadığı takdirde nedeninin belirlenmesi şeklinde ta…
The sofa, which is one of the most characteristic elements in traditional Turkish homes, is an important living space in the household that allows the continuity of social life based on the construction of traditional housing units. The traditional housing u…
İnsanlar arasındaki bilgi alışverişinin temeli olan iletişim yazıyla kalıcılık kazanmıştır. Yazı tarih öncesi dönemlerden günümüze içinde bulunulan dönemi aktarmak için bir köprü görevi üstlenmiştir. İlk yazının bulunuşundan günümüze pek çok aşamadan geçerek…
As the world is running out of fossil fuels and the environment is being seriously damaged by the combustion residuals of the internal combustion engines, the world countries have begun to search alternative ways for mobility. Lightweight electric vehicles w…
In the fifth generation (5G), the traditional restrictions that limit the capacity of wireless communication must be overcome. Non-orthogonal multiple access (NOMA) is a promising solution capable of overcoming these constraints to meet the requirements of 5…
Hyperspectral images offer a good separability among land cover classes, owing to their advantages to provide spectral bands with narrow wavelength intervals. It is also possible to further increase classification accuracy of hyperspectral images by integrat…
In our global World, studies on food and food related-sectors, which are among the leading sectors in Turkey, continue to gain momentum to increase productivity and quality. In parallel, the developments in the information technology motivate researchers to ga…
Today, with the rapidly development of technology, artificial neural networks (ANN) usage as an alternative to statistical methods increase in many fields such as finance sector, medical science, defense industry, production, robot systems, image processing an…
The quality control process for determining fabric faults causes high cost and time loss when performed with human eyes. Adding a real-time system to the fabric production mechanisms is very difficult to detect mistakes. In this study, 5 MP Raspberry Pi camera…
Multi-seeded YBCO superconductors (cylindrical size) 32 mm in diameter were fabricated by top-seeded melt growth (TSMG). Melt-processing was performed using a precursor containing 75 wt % of Y123 and 25 wt % of Y211 with 0.5 wt % of CeO2. Trapped magnetic fi…
Pansharpening, which is transferring the spatial content of a high-resolution panchromatic (PAN) band into a lowerresolution multispectral (MS) image to produce a spatially enhanced MS image, has always been one of the hottest topics of image processing. Nume…
