In the absence of treatment, it can lead to serious health problems such as heart attack and stroke. Polysomnography is the gold standard examination methods used in the diagnosis of the disease. In this study, EEG signals obtained from the polysomnography recording are divided into sub-bands and their epochs in pre apnea, intra apnea and post apnea were analyzed. Non-parametric power spectral density (PSD) detection methods (Periodogram, Welch and Multi Taper) applied to the EEG signals were compared.","PeriodicalId":431660,"journal":{"name":"2016 Medical Technologies National Congress (TIPTEKNO)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115816174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study demonstrates that when cell membranes are modeled after fractional order circuit elements, analytical solutions to the network equations can be found that describe the dynamic responses of any given cell to a single stimulus in greater and more accurate detail. Transfer function and the driving point impedance for this circuit network are derived in the fractional domain based on the application of the transmission matrices concept. Furthermore, necessary MATLAB simulations are performed on the network and are included as a numerical example.","PeriodicalId":431660,"journal":{"name":"2016 Medical Technologies National Congress (TIPTEKNO)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116881492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Familiar and non familiar stimuli were determined according to participants' rating and EEG segments related to familiar and non familiar stimuli were analyzed. Discrete wavelet transform (DWT) was used as filter to get the interested frequency range of EEG signals. Power spectral density (PSD) of filtered EEG signals was obtained by using Welch method. The power spectrum of EEG signals was considered as familiarity effects of emotional stimulus. As a conclusion, it was observed that different states of familiarities related to emotional stimulus cause different values of PSD over EEG signals.","PeriodicalId":431660,"journal":{"name":"2016 Medical Technologies National Congress (TIPTEKNO)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124847633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The early diagnosis of melanoma is a key factor that remarkably reduces the mortality rate. Diffuse reflectance spectroscopy is a very useful device for diagnosis and treatment purposes under in-vivo conditions. At this point, the aforementioned device, which takes into account the scattering of tissue, is to determine the concentration of chromophores (or optical absorbers) due to attenuated light strikes to the superficial layer of tissue. Laser-type light based imaging techniques in medical diagnosis substantially produce good results. So the aim of this study is to estimate HbO2 % and Hb% concentrations.","PeriodicalId":431660,"journal":{"name":"2016 Medical Technologies National Congress (TIPTEKNO)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121643276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the classification stage, Support Vector Machines (SVM), K-Nearest Neighbors (K-NN) and Discriminant Analysis (DA) algorithms were employed.

Various length windows have been used for feature extraction. Various feature attribute sets have been implemented. Valence and arousal have been categorized and relationship between physiological signals and arousal and valence has been studied using Random Forest machine learning algorithm. We have achieved 71.53% and 71.04% accuracy rate for arousal and valence respectively by using only galvanic skin response signal.

In this study, tracking of personal and patients in the hospitals has been performed by using this feature of active RF-ID system. Thus, by tracking personal within the hospital it is aimed to take mandatory actions for hygiene control at special locations where hygiene rules must be strictly followed. Within this context, a system has been designed for personal to fulfill his responsibilities at this regard.
