Real-Time Output Feedback Neurolinearization
An adaptive input-output linearization method for general nonlinear systems is developed without using states of the system. Another key feature of this structure is the fact that, it does not need model of the system. In this scheme, neurolinearizer has few weights, so it is practical in adaptive situations. Online training of neuroline...
متن کاملContinuous assessment of cardiac output during exercise using real time flow with fast GPU reconstruction
Background The haemodynamic response to exercise is an important health marker. Phase contrast MR (PCMR) is an accurate method of assessing cardiac output and novel realtime sequences allow assessment of flow during exercise. However, such sequences often have time-consuming reconstruction algorithms, which prevent continuous cardiac output monitoring during exercise. Graphical processing units...
متن کاملReal time flow with fast GPU reconstruction for continuous assessment of cardiac output
PURPOSE To demonstrate the feasibility of real-time phase contrast magnetic resonance (PCMR) assessment of continuous cardiac output with a heterogeneous (CPU/GPU) system for online image reconstruction. MATERIALS AND METHODS Twenty healthy volunteers underwent aortic flow examination during exercise using a real-time spiral PCMR sequence. Acquired data were reconstructed in online fashion us...

متن کاملComparison of esophageal Doppler, pulse contour analysis, and real-time pulmonary artery thermodilution for the continuous measurement of cardiac output.
OBJECTIVE Continuous measurement of cardiac output (CCO) is of great importance in the critically ill. However, pulmonary artery thermodilution has been questioned for possible complications associated with right heart catheterization. Furthermore, measurements are delayed in the continuous mode during rapid hemodynamic changes. A new pulmonary artery catheter CCO device (Aortech, Bellshill, Sc...
