Localization of myocardial infarction and its developmental stages are indicated by: T wave, ST-segment and QRS complex (Q wave). T-wave inversion shows the zone of reduced blood supply (ischemia), ST segment (elevation or depression) points at the ischemic injury- lesion, and a deep Q wave indicates a developed infarction. Using these characteristics, a software application is developed. The application aim is to enable effec-tive monitoring of patients with urgent acute conditions as well as timely therapeutic effect. The software application is devel-oped in VisualStudio2010 and it provides a practical and clear user interface. It also detects changes related to the QRS com-plexes, P and T waves (using Wavelet transformation and various filters for eli...

A robust LQR is proposed in this paper not only to stabilize the pendulum in upright position but also to make the cart system to track the given reference signal even in the presence of disturbance. The control scheme of pendulum system consists of two controllers such as swing up controller and stabilizing controller. The main focus of this work is on the design of stabilizing controller which can accommodate the disturbance present in the system in the form of wind force. An optimal LQR controller with well tuned weighting matrices is implemented to stabilize the pendulum in the vertical position. The steady state and dynamic characteristics of the proposed controller are investigated by conducting experiments on benchmark linear inverted pendulum system. Experimental results prove that the proposed LQR controller can guarantee the inverted pendulum a faster and smoother stabilizing process with less oscillation and better robustness than a Full State Feedback (FSF) controller by pole placement approach.
