Article Citation - WoS: 3Citation - Scopus: 3Application of Fnbdt/Scip Protocol on Local Area Network and Determination of Limit Values(Gazi Univ, Fac Engineering Architecture, 2010) Dilli, Orkun; Akcam, Nursel; Koyuncu, Murat; Information Systems EngineeringFast progress in technologies affects all the domains as well as the communication systems. Different types of systems or devices are developed and given to the services without losing time. Although these progresses, in general, have positive effects sometimes they may cause some problems. One of these problems is that the different terminal devices based on ISDN, PSTN and IP cannot communicate end-to-end with each other in a seamless secure way. In this study, FNBDT (Future Narrow Band Digital Terminal)/SCIP (Secure Communication Interoperability Protocol) protocol, which is developed for end-to-end secure communication of different terminal devices communicating on different networks, is tested from different perspectives using terminal emulator on IP Networks. These types of study have great importance in terms of providing some feedbacks to the development of FNBDT/SCIP and, as one of the initial work on this topic, this study will contribute to the future works in the area.Conference Object Part-Based Object Extraction for Complex Objects(Ieee, 2014) Koyuncu, Murat; Cetinkaya, BasarIndexing requirement for efficient accessing to visual data has been increased with the widespread use of multimedia applications. Satisfaction of this requirement mostly depends on the automatic extraction of objects in the visual data. In this study, component-based object extraction method is compared with object extraction in its entirety. Applied method, implemented system and conducted tests are presented in this paper. Test results show that, even in the case of a good segmentation is achieved for whole object, object components are classified more successfully compared to whole object.Conference Object Feature Fusion in Part-Based Object Detection(Ieee, 2015) Koyuncu, Murat; Cetinkaya, BasarIn this study, classification of complex objects in images as a whole is compared with classification of its distinctive components using different features. In addition, the impact of feature fusion in part-based object detection is investigated. Applied method, implemented system, conducted tests and their results are presented in this paper. Test results show that, even in the case of a good segmentation, object components are classified more successfully compared to whole object and feature fusion method improves the obtained results to a certain degree.Article Fnbdt/scıp Protokolünün Yerel Alan Ağında Uygulanması ve Sınır Değerlerin Tespit Edilmesi(2010) Dilli, Orkun; Akçam, Nursel; Koyuncu, MuratTeknolojideki hızlı değişim her alanda olduğu gibi haberleşme sistemlerinde de yaşanmaktadır. Geliştirilen farklı sistemler veya cihazlar zaman kaybedilmeden kullanıma sunulmaktadır. Söz konusu değişim genelde olumlu olmakla birlikte bazen olumsuz sonuçlara da yol açabilmektedir. Bu olumsuz sonuçlardan bir tanesi, ISDN, PSTN ve IP tabanlı haberleşme cihazlarının birbirleriyle uçtan uca güvenli olarak haberleşme yapamamasıdır. Bu çalışmada, farklı haberleşme ağları üzerinde uçtan uca emniyetli haberleşmenin yapılması amacıyla geliştirilen FNBDT (Future Narrow Band Digital Terminal)/SCIP (Secure Communication Interoperability Protocol) protokolü, emulatörler vasıtasıyla IP ağ üzerinde değişik açılardan test edilmiştir. Bu tür çalışmaların yapılmasının FNBDT/SCIP protokolünün gelişimine katkıda bulunmak açısından büyük önem arz etmekte olduğu ve sunulan çalışmanın bu alanda gerçekleştirilmiş ilk çalışmalardan birisi olması nedeniyle de gelecekte konuyla ilgili yapılacak çalışmalara katkı sağlayacağı düşünülmektedir.
