Airframe and Powerplant Maintenance
(2012)
The Atılım University Department of Airframe and Powerplant Maintenance has been offering Civil Aviation education in English since 2012. In an effort to provide the best level of education, ATILIM UNIVERSITY demonstrated its merit as a role model in Civil Aviation Education last year by being granted a SHY 147 certificate with the status of “Approved Aircraft Maintenance Training Institution” by the General Directorate of Civil Aviation. The SHY 147 is a certificate for Approved Aircraft Maintenance Training Institutions. It is granted to institutions where training programs have undergone inspection, and the quality of the education offered has been approved by the General Directorate of Civil Aviation. With our Civil Aviation Training Center at Esenboğa Airport (our hangar), and the two Cessna-337 planes with double piston engines both of which are fully operational, as well our Beechcraft C90 Kingait plaine with double Turboprop engines, Atılım University is an institution to offer hands-on technical training in civil aviation, and one that strives to take the education it offers to the extremes in terms of technology. The Atılım university Graduate School Department of Airframe and Powerplant Maintenance is a fully-equipped civil aviation school to complement its theoretical education with hands-on training using planes of various kinds. Even before their graduation, most of our students are hired in Turkey’s most prestigious institutions in such a rapidly-developing sector. We are looking forward to welcoming you at this modern and contemporary institution for your education in civil aviation.

Abstract

Bu tezde, önceden eğitilmiş birkaç CNN ve CNN yapımız endoskopik görüntülerde erken mide kanserinin otomatik olarak tespit edilmesine sunulmuştur. İlk aşamada, iki tip normal ve görüntü veri kümelerinin kanseri kullanılarak yapılan transfer öğrenimi, MATLAB 2018 kullanılarak mide kanseri tespiti için önceden eğitilmiş ağlar gerçekleştirildi. Daha sonra elde edilen sonuçlar birbirleriyle karşılaştırıldı ve ayrıntılı olarak tartışıldı. İkinci aşamada, CNN kullanılarak önerilen yeni yapı. Önerilen yapı SoftMax sınıflandırıcılı 8 katmandan oluşur. Son katmanda SoftMax tarafından sınıflandırılan evrişimsel katmanlarla çıkarılan yüksek seviye özellikler. Önerilen ağ 99.88% sundu ve bu da önceden eğitilmiş birkaç ağla karşılaştırıldığında yüksek sonuçtur. Ayrıca, önerilen ağ, çeşitli transfer öğrenme teknikleriyle karşılaştırıldığında dikkate değer bir yürütme süresi sundu.
In this thesis, several pre-trained CNN and our CNN structure presented to automatic detection of early gastric cancer in endoscopic images. In the first stage, the transfer learning using two types normal and cancer of image datasets, the pre-trained networks executed for gastric cancer detection using MATLAB 2018. Then, the obtained results compared with each other and discussed in detail form. In the second stage, new structure proposed by using CNN. The proposed structure consists from 8 layers with SoftMax classifier. The extracted high-level features by convolutional layers classified by SoftMax in last layer. The proposed network presented 99.88% which is high result when compared with numerous performed pre-trained networks. Furthermore, the proposed network presented remarkable execution time when compared with several transfer learning techniques.
