    • Estimating the chance of success in IVF treatment using a ranking algorithm 

      Güvenir, H. A.; Misirli, G.; Dilbaz, S.; Ozdegirmenci, O.; Demir, B.; Dilbaz, B. (Springer, 2015)
      In medicine, estimating the chance of success for treatment is important in deciding whether to begin the treatment or not. This paper focuses on the domain of in vitro fertilization (IVF), where estimating the outcome of ...
    • An experimental study on speech interference in public leisure spaces 

      Yilmazer, Semiha; Gezginer, Pelin Meriç (Institute of Noise Control Engineering, 2010)
      Physical comfort requirements of users in the non-acoustical spaces, leisure space, and usability of the space in long-term period should be taken into consideration in terms of sustainability of the space. The aim of this ...
    • Flame detection for video-based early fire warning for the protection of cultural heritage 

      Dimitropoulos, K.; Günay, Osman; Köse, Kıvanç; Erden, Fatih; Chaabene, F.; Tsalakanidou, F.; Grammalidis, N.; Çetin, Enis (2012-10-11)
      Cultural heritage and archaeological sites are exposed to the risk of fire and early warning is the only way to avoid losses and damages. The use of terrestrial systems, typically based on video cameras, is currently the ...
    • Generalizing predicates with string arguments 

      Cicekli, I.; Cicekli, N. K. (Springer New York LLC, 2006-06)
      The least general generalization (LGG) of strings may cause an over-generalization in the generalization process of the clauses of predicates with string arguments. We propose a specific generalization (SG) for strings to ...
    • Heterogeneous inference in design 

      Akman, Varol (Publ by ASME, New York, NY, United States, 1992)
      For those of us involved in the attempt to construct formal models and environments in which the world of design can be subjected to scientific experimentation, the raison d'etre of logic has been rather well-understood. ...
    • Improving genome assemblies using multi-platform sequence data 

      Kavak, P.; Ergüner, B.; Üstek, D.; Yüksel, B.; Saǧıroǧlu, M. Ş.; Güngör, T.; Alkan, Can (Springer, 2015-09)
      Accurate de novo assembly using short reads generated by next generation sequencing technologies is still an open problem. Although there are several assembly algorithms developed for data generated with different sequencing ...
    • Interactive training of advanced classifiers for mining remote sensing image archives 

      Aksoy, Selim; Koperski, K.; Tusk, C.; Marchisio G. (ACM, 2004)
      Advances in satellite technology and availability of down-loaded images constantly increase the sizes of remote sensing image archives. Automatic content extraction, classification and content-based retrieval have become ...
    • Investigation of multi-objective optimization criteria for RNA design 

      Hampson, D. J. D.; Sav, Sinem; Tsang, H. H. (IEEE, 2017-12)
      RNA design is the inverse of RNA folding and it appears to be NP-hard. In RNA design, a secondary structure is given and the goal is to find a nucleotide sequence that will fold into this structure. To find such sequence(s) ...
    • Issues in commonsense set theory 

      Pakkan, M.; Akman, V. (Springer/Kluwer Academic Publishers, 1994)
