Pyrite is a mineral which has very low economic value although it is very common in the world. When the pyrite is concentrated together with the precious minerals, it produces a decrease in the grade and an increase in the smelting costs of the precious minera…

Dünyadaki veri miktarı büyük bir hızla artmaktadır. Günümüzde veriler bilim insanları tarafından en değerli hammadde olarak düşünülmektedir. Veri madenciliği çalışmaları gelişmiş ülkeler için kritik bir konudur. Bu nedenle her alanda veri çalışmalarına büyük…

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…

Today, there is an ever-increasing use of digital tools in design processes. Markedly, Virtual Reality (VR) applications have secured a prominent place in the interior architecture industry. The potential use of digital tools in the scope interior architecture…

In this paper we presents an application of deep learning techniques to recognize handwritten source code characters. Although there are many works on the handwritten character recognition (HCR) problem, very few works have been done about the offline handwrit…

A serial hybrid optical amplifier composing of two amplification stages of erbium-doped fiber (EDF) amplifier covered C-band window and Raman fiber amplifier (RFA) covered L band window demonstrated. In this paper, the optimizations were done to obtain the opt…

Increasing in wireless communications systems is caused to increase in the need of the frequency spectrum. CR (Cognitive Radio) measure or sense frequency spectrum activities on spectrum bands whether they are idle or used by licensed users. According to sensi…

Open-finance services must prepare for cryptographic transitions while evaluating quantum-computing opportunities against classical alternatives. These decisions require different evidence but concern shared data, software, suppliers, and owners. This paper de…

Tüm dünyada özellikle de kent merkezlerinde yaşayan insan nüfusu her geçen gün artmaktadır. Nüfus artışına bağlı olarak sosyal, ekonomik ve çevre sorunlarını da her geçen gün artmaktadır. Günümüzde kent merkezlerinde görülen en önemli çevre sorunlarından biri …

Digital image processing has become popular research area recently because of its widespread application compatibility such as security, robotics, quality control, face authentication. Skin segmentation methodology, which is a tool of digital image processing,…

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…

It was aimed to find the structural discontinuities of the Eastern Anatolia Region by using horizontal gradient magnitude technique. When determining the structural discontinuities of the region, the maximum amplitudes of the horizontal gradient magnitude we…

Over the past century, before and after the pandemic of COVID-19, workers in multiple sectors, such as medical, chemical, and nuclear, have been required to wear face masks during duties. However, physical 24/7 supervision is nearly impossible in public places…

Ağır metal kirliliği dünya çapında ciddi boyutlara gelmiş bir sorundur. Günümüz endüstriyel toplumunda, toksik kimyasallara ve metallere maruz kalmaktan kaçınmanın bir yolu bulunmamaktadır. Çevrenin önemli bir bölümü olan tarım toprakları bu olgunun bir parças…

Bu çalışmanın hedefi, silis kumu (SK) ve Termik Santralinden elde edilen uçucu kül (UK) kullanılarak geopolimer harç üretmektir. Bu çalışmada uçucu külü aktive etmek için çimento yerine, aktivatör (Na2SiO3 ve NaOH) ve uçucu kül (UK) birleştirilip bağlayıcı mad…

Tüm dünyada evsel ve endüstriyel üretim işlemlerine bağlı olarak atık maddeler üretilmektedir. Atık maddelerin miktarı her geçen gün artmaktadır. Ayrıca atık maddelerin depo edileceği alanlar azalmakta ve tekrar kullanım alanları sınırlıdır. Atık maddeler çeşi…

The particulate matters in ambient air were sampled in Denizli, Turkey in winter and spring using Bergerhoff Method. The average dry deposition fluxes were calculated as 152.1 ± 30.7 mg m-2 day-1 and 333.9 ± 214.2 mg m-2 day-1 in spring and winter, respectivel…

Traffic flow forecasting has an important place in designing a successful intelligent transportation system. The success of the forecasting is related to the accuracy and timely acquisition of the traffic flow data. The inadequacy in the number of data has led…

Wireless Sensor Networks have many application fields including both industrial and military usages. They are used for monitoring temperature, distance, light, and motion in laboratories and/or application specific environments. This paper focuses on developin…

Doğru akım motoru servo sistemlerde önemli bir tahrik unsurdur. Hız veya konum denetimi gerektiren sistemlerde kolay denetlenebildiği ve yüksek performans gösterdiği için sıkça kullanılmaktadırlar. Bu çalışmada, bir DC servo sistemin modellenmesi, durum değişk…
