    • Sketch recognition using transfer learning 

      Sert, Mustafa; Boyaci, Emel (2019)
      Humans have an excellent ability to recognize freehand sketch drawings despite their abstract and sparse structures. Understanding freehand sketches with automated methods is a challenging task due to the diversity and ...
    • Smoothed one-core and core-multi-shell regular black holes 

      Azreg-Ainou, Mustapha (2018)
      We discuss the generic properties of a general, smoothly varying, spherically symmetric mass distribution D(r,theta), with no cosmological term (. is a length scale parameter). Observing these constraints, we show that ...
    • The Source of Heart Rhythm Changes Caused by Swallowing 

      Yildiz, Metin; Domaz, Serian (2020)
      Swallowing can lead to the development of syncope in people who have difficulty swallowing during food intake. It has shown that even spontaneous saliva swallowing can change heart rate variability (HRV). Recently, it has ...
    • Sparsity-driven weighted ensemble classifier 

      Erdem, Hamit; Ozgur, Atilla; Nar, Fatih (2018)
