ÖZETSteady-state visual evoked potentials (SSVEPs) have been designated to be appropriate and useful for many areas in clinical neuroscience, cognitive, and in engineering. SSVEPs have become popular recently, due to their advantages such as high bit rate, simple system structure, and short training time, etc. To design SSVEP based BCI system, signal processing methods appropriate to the signal structure should be applied. One of the most appropriate signal processing methods of these non-stationary signals is the Wavelet Transform. After literature searched, we noticed that there was no study ...Daha fazlası
ABSTRACTDiabetes Mellitus (DM) is a chronic disease that progresses rapidly. Today, thenumber of diabetic patients is increasing day by day, but treatment methods arebeginning to be inadequate due to the insufficient time, financial deficiencies andother restrictions.

In terms of the course of diabetestreatment, it is necessary for the self-management of the patient to follow thediabetes education and appli ...Daha fazlası
ÖZETBu tezde, EOG sinyalleri kullanılarak hareket yeteneği kısıtlı engelli bireyler için gerçek zamanlı çalışmalara uygulanması kolay bir tekerlekli sandalye kontrol algoritması geliştirilmiştir.Bu çalışmada, yaşları 20-26 arasında değişen 26 bireyden EOG sinyalleri alınmıştır. EOG sinyalleri olarak yatay EOG, sağ göz düşey EOG ve sol göz düşey EOG sinyalleri kayıt edilmiştir. Daha sonra her bir EOG kanalı 150 ms’lik medyan süzgecine tabi tutulmuştur. Böylece istemsiz yapılan göz kırpmaları ve çeşitli diğer gürültüler sinyalden arındırılabilmiştir. Geliştirilen algoritmaların girişine, her den ...Daha fazlası
ABSTRACTPreterm newborns are unlikely to live without any additional support. Babies born in this way need special care and a place that would imitate their mother’s womb as much as possible. The environmental conditions like the temperature, humidity, noise, light intensity, etc. need to be carefully managed. In addition to managing the environment, it is necessary to record vital data such as baby's temperature and pulse and record any changes so that they can be examined later. Since the systems that carry out these mentioned controls are very expensive, there are still hospitals that do no ...Daha fazlası
