By curve fitting the proposed model to the measured oscillometric pulses using a nonlinear optimization technique, we demonstrate that an arbitrary oscillometric pulse can be modeled and consequently noise and artifacts can be reduced. As each sinusoid is precisely expressed by its amplitude, phase and frequency, the proposed method provides a compressed representation of the oscillometric pulses. We show that the proposed method achieves a compression ratio of 60 Fs/HR 2N+4, where HR is the heart rate in beats/min, Fs is the sampling frequency in Hz, and N is the number of harmonics considered in the model. New methods for detecting, replacing, and correcting the outliers based on the characteristics of the outlier neighboring pulses are also proposed in this paper.","PeriodicalId":221120,"journal":{"name":"2016 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132920675","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}

With the advent of sensor based technologies, it has become possible to create wearable wireless biometric sensor networks, known as Body Sensor Networks (BSNs) which allow people to collect their health data and send it remotely for further analysis and storage. Research has shown that the use of BSNs enables remote wireless diagnosis of various health conditions. In this paper, we propose a novel layered architecture for smart healthcare system where health community service providers, patients, doctors and hospitals have access to real time data which has been gathered using various sensory mechanisms. An experimental case study has been implemented for evaluation. Early results show benefits of this system in improving the quality of health care.","PeriodicalId":221120,"journal":{"name":"2016 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132933990","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 quality of fMRI data is best among other modalities such as Electroencephalography (EEG) and Magnetoencephalography (MEG). In fMRI, normally number of features are more than the number of instances so it is necessary to select the features and do dimension reduction to remove noisy and redundant data. Many techniques and methods are used to select the significant features (voxels). In this paper, the significant voxels are selected within the anatomical region of interest (ROI) based on the absolute values. In this study, we have predicted the brain states using two machine learning algorithm, i.e, Radial basis function (RBF) network and Naïve Bayes. A visual experiment with two categories is done. In conclusion, it is shown that less number of voxels and specific brain regions can increase the accuracy of prediction.","PeriodicalId":221120,"journal":{"name":"2016 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117328071","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}

We had previously demonstrated an image based quantitative method to scan fluorescence labeled lateral flow test strips.

A new wideband emission filter was used instead of the previous narrowband filter and enhanced signal levels were obtained. Standard HbA1c calibrator set was used to evaluate the area ratios for various concentration levels of the analyte and generate the calibration curve. A straight line fit to the calibration data showed R-squared value to be 0.99. Repeatability of the instrument in successive test runs was evaluated to be fairly good with CV less than 4%. Inter-day repeatability of the instrument was also studied and the results were moderate.","PeriodicalId":221120,"journal":{"name":"2016 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114737400","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}

Each training session, lasting about 80 min, consisted of general warmup and stretching exercises, free-body exercises, exercises with small implements (clubs, dumbbells, medicine ball), aerobic activity consisting of walking/running on the treadmill or open ground and cooling-down exercises. The training impulse method was utilized to indirectly quantify the amount of exercise intensity on the basis of heart rate values assessed during training sessions. The value adopted for training impulses prescribed for patients was about 130 arbitrary units and corresponded to 50 ~ 60% of their maximum oxygen consumption. Immediately before and at the end of the training patient took an incremental cycle-ergometer test (20W every 3 min), up to exhaustion, in such a way as to assess maximum values of: oxygen consumption, workload and the ratio between these two variables (i.e. the oxidative cost), heart rate, systolic and diastolic arterial blood pressures. At the trial end, in correspondence of the maximum workload reached during the cycle-ergometer exercise, both body mass and body mass index had significantly decreased, as had diastolic arterial blood pressure and oxidative cost of exercise, while fat free mass had increased, when refered to the trial entry. It can be concluded that the precise amount of training, as established by utilizing training impulses, may facilitate the choice of the strategy to ameliorate physical and mental health in postmenopausal obese women.","PeriodicalId":221120,"journal":{"name":"2016 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115072774","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 this study, a new approach was proposed to pattern classification for electrocardiography (ECG) signals based on Gaussian mixture model and logarithmic linearization. The objective of this study was to identify and classify QRS complexes on ECG patterns. For this purpose, a high performance method to classify and discriminate various ECG patterns was developed. Besides, a comparison algorithm which evaluates time series signals was established, and the limitation of its parameters was determined in order to attain high performance in ECG classification. The proposed algorithm has been tested on the data from 20 normal subjects and 22 additional normal data sets from MIT-DB database. After the improvement by the proposed algorithm, we observed 99.21% and 99.24% of recognition rates in ECG data from 20 normal subjects and MIT-DB database, respectively. The results showed that the proposed algorithm achieved a high performance to classify and discriminate various ECG signals.","PeriodicalId":221120,"journal":{"name":"2016 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134235697","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}
