    In this paper we investigated the component-based specific issues that might affect project cost estimation. Component-based software development changes the style of software production. With component-based approach the ...
  • Component-based software development with component variants 
    Altunel, Yusuf; Tolun, Mehmet R. (Acta Press Anaheim, 2007)
    Variants are the new units suggested for component-based software implementation to contain just one set of features that a traditional component might normally contain. They help us to implement the specialization of ...
  • Hand gesture recognition in variable length sequences 
    Choupani, Roya; Tolun, Mehmet R. (2005-09)
    Using hand gestures in human computer interaction has been a major challenge during the recent years. Many of the hand gesture recognition systems however, have been based on the recognition of hand postures and estimating ...
  • Hybrid Expert Systems: A Survey of Current Approaches and Applications 
    Şahin, S.; Tolun, Mehmet R.; Hassanpour, Reza (Expert Systems With Applications, 2012-03)
    This paper is a statistical analysis of hybrid expert system approaches and their applications but more specifically connectionist and neuro-fuzzy system oriented articles are considered. The current survey of hybrid expert ...
  • Induction for radiology patients 
    Yıldırım, Pınar; Tolun, Mehmet R. (Springer, 2009)
    This paper represents the implementation of an inductive learning algorithm for patients of Radiology Department in Hacettepe University hospitals to discover the relationship between patient demo-graphics information and ...
  • Main issues in scalable video coding: A review 
    Choupani, Roya; Tolun, Mehmet R. (2007)
    Video streaming over the Internet has gained popularity during the recent years which is mainly the result of the introduction of videoconferencing and videotele-phony. These in turn have made it possible to bring to life ...
  • Mining Medlıne for the Treatment of Osteoporosis 
    Yıldırım, Pınar; Çeken, Çınar; Hassanpour, Reza; Esmelioğlu, Sadık; Tolun, Mehmet R. (Springer, 2012-08)
    In this paper, we consider the importance of osteoporosis disease in terms of medical research and pharmaceutical industry and we introduce a knowledge discovery approach regarding the treatment of osteoporosis from a ...
  • Multiple description coding for SNR scalable video transmission over unreliable networks 
    Choupani, Roya; Wong, Stephan; Tolun, Mehmet R. (Springer, 2014-04)
    Streaming multimedia data on best-effort networks such as the Internet requires measures against bandwidth fluctuations and frame loss. Multiple Description Coding (MDC) methods are used to overcome the jitter and delay ...
  • Multiple Description Scalable Coding for Video Transmission over Unreliable Networks 
    Choupani, Roya; Wong, Stephan; Tolun, Mehmet R. (2009)
    Developing real time multimedia applications for best effort networks such as the Internet requires prohibitions against jitter delay and frame loss. This problem is further complicated in wireless networks as the rate of ...
