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
ÖZETTıbbi görüntüleme, herhangi bir invaziv işlem olmaksızın vücudun içinin görüntülerini oluşturmaktır. X-ışınlarının keşfi, tıbbi görüntülemenin temelini oluşturur. Zamanla yeni görüntüleme yöntemleri de geliştirilmiştir. Manyetik rezonans görüntüleme, pozitron emisyon tomografisi bu yöntemlerin örnekleri olabilir. Bununla birlikte, x-ışınları bir temel uygulama olarak kalmıştır. Her görüntüleme yöntemi gibi, x-ışınları da dezavantajlara sahiptir ve geliştirmeye ihtiyaç duyar. Üreteç temelli sorunların üstesinden gelme amacıyla yeni x-ışını üretim metotları geliştirilmeye çalışıldı. X-ışını ...Daha fazlası
ABSTRACTIn this thesis, an Arduino extension board (shield) is designed to take theelectrocardiography (ECG) signals. Firstly, the positive and negative terminals of an ECG signal are selected to determine which input pins are connected to these terminals. User can select one of eight possible inputs for each terminal, which means the user can apply one of the possible 64 channel combinations to inputs of the design. Then a dedicated instrumental amplifier amplifies the signal. The voltagegain of the amplifier can be selectable among available options. The amplified ECG signal is filtered in a ...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. Diabetes education and treatment are very important for thediabetic to survive. Diabetes treatment is practiced in many areas of life from thenutrition habits to the social life activities. 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
Motor imagery (MI) task classification is highly prevalent in Electroencephalography
(EEG)-based Brain-Computer Interface (BCI) research area. Extremity movement task
classification and finger movement classification studies are presented in this thesis.
In extremity movement classification, binary-class (right hand and left hand) and
multi-class (right hand, left hand, right hand, and left hand) classifications are
performed using 4 different feature extraction approaches and statistically
significance-based feature selection (the independent t-test, one-way ANOVA test).
Firstly, time- ...Daha fazlası
The aim of this thesis was to develop a wearable tele-physiotherapy device that addresses the remote elbow joint rehabilitation. The developed device consists of a wearable exoskeleton equipped with servo motor, joint angle sensor, EMG sensor, battery and Wi-Fi module. By connecting with the Android mobile application, it enables real-time monitoring of EMG data and programming of personalized exercise programs. The device offers convenience and comfort to patients by eliminating the need for face-to-face physiotherapy sessions and aims to reduce treatment costs and treatment time.
The develo ...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
The aim of this thesis was to develop a wearable personal trainer device supported
with an application that works on mobile devices to analyze arm position and muscle
state during a weight exercise. The wide popularity of an active lifestyle combined
with people's demands for well-informed workouts, a need for personalized training
devices is detected. Main objective was to design a wearable tracking system that could
detect and track arm position and collect real time data from desired muscles (biceps
brachii, brachialis, coracobrachialis, and triceps brachii) to track exercise effectiv ...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
