(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

Hücre sayımı ve bu hücrelerin sınıflandırılması için kullanılan yöntemler mikro biyoloji ve hücre biyolojisi alanında önemli bir yer tutmaktadır. En temel sayma mikroskop aracılığıyla Hemositometre kullanılarak insan tarafından yapılır. Bu süreçte hücre sayısı ve canlılığını belirlemek için kullanılan en ekonomik ve en yaygın teknik boya dışlama yöntemidir. Bu çalışmada, hücre canlı-ölü ayrımı yapabilen yeni bir görüntü tabanlı hücre sayımı yaklaşımı (NIBA-C) önerilmiştir. Önerilen yöntemin başarısını değerlendirmek için aynı görüntüler, yöntem ile elde edilen değerler klasik boya dışlama yöntemi ile elde edilen sonuçlar ile karşılaştırılmıştır. Yöntemi segmentasyon ve ardından görüntülerin sınıflandırılması oluşturur. Segmentasyon aşamasında Hough Dönüşümü kullanılmıştır. Yapay Sinir Ağları hücre-hücre olmayan ve canlı-ölü hücre görüntü sınıflandırmasında kullanılmıştır.Bu çalışmada; önerilen yöntem NIBA-C %70 in üzerinde yerbulma ve %50 üzerinde canlı ölü ayrımı yapabilme yetenegi sergilemiştir.
The methods to determine the amount and viability of cells play an important role in the field of microbiology and cell biology. The basic cell counting process is through microscopic analysis using hemocytometer, performed by a technician. In this process, the most economical and widely used technique is dye-exclusion method to determine cell number and viability. In this study, a novel image based approach for cell counting (NIBA-C) is proposed with a capability of distinction between alive from dead during the process. For evaluating the success of proposed method, the results obtained by the method are compared with microscopic cell viability count by virtue of classical dye-exclusion method. The method depends first on segmentation of the cells and then classification of them. Segmentation of cell images is achieved using Hough Transform. Artificial Neural Network is used to distinguish cell images from non-cells and dead cell images from alive cells.In this study, it is concluded that the cell analysis by NIBA-C accomplishes 70 % more accuracy in finding the correct location of the cells, and more than 50% reliable in defining viable cells in comparison with the classical cell count method based on dye-exclusion.
