Background Alzheimer’s disease (AD) underlies dementia for millions of people worldwide, and its occurrence is set to double in the next 20 years. Currently, approved drugs for treating AD only marginally ameliorate cognitive deficits, and provide limited symptomatic relief, while newer substances under therapeutic development are potentially years away from benefiting patients. Melatonin (MEL) for...
Beside the measurement of flow velocity through mitral valve by pulsed Doppler, and measurement of velocity of myocardium by tissue Doppler imaging, estimation of diastolic function of left ventricle can also be made by measuring velocity of propagation of vortex using color Doppler M-mod imaging. Automated measurement has not become a practice yet because different methods produce different results...
For an automated classification of heart murmurs there is a need of detailed analysis of heart sounds both in time and frequency domain. In this work the possibility of extracting the formant frequencies from the phonocardiogram was examined. The purpose of examination described here was to obtain a result which could facilitate the classification by offering additional information about the sound...
In this paper an efficient heart beat classification algorithm for mobile devices is presented. A simplified ECG model is used for feature extraction in the time domain. QRS complex is modeled by two straight lines while P and T waves are modeled by parabolas. The T wave asymmetry is achieved using a fourth degree parabola, whereas the P wave is modeled by the second degree parabola. The model parameters...
This article contents a brief description of an e-learning material, a set of interactive online exercises developed for the education of fuzzy systems with the aim to get a supplement to theoretical lessons. Students can do experiments by changing the input parameters, and after submitting the inputs, they get the results immediately via the Internet in form of a Web document containing variables...
