Indexes PRx and Mx have been formerly introduced to assess cerebral autoregulation and have been shown to be associated with 3-month clinical outcome. In a mixed cohort of neurocritical care patients, we retrospectively investigated the impact of selected clinical characteristics on this association. Forty-one patients (18–77 years) with severe traumatic(More)
Linear Model-based Test and Diagnosis (MbT&D) has been successfully applied to single-block modules like Digital-to-Analog Converters (DACs) with a static non-linear transfer characteristic. For Multi-block modules, a diagnosis methodology is needed that can deal with cascades of several linear and nonlinear blocks. In contrast to non-linear methods,(More)
This paper presents a new application field for the Goertzel algorithm. The test of mixed-signal circuits involves the generation and analysis of signals. A standard method for the signal analysis is the Fast Fourier Transform (FFT algorithms). Such complex algorithms are not suitable for BIST (Built-In Self-Test) or BOST (Built-Off Self-Test) solutions due(More)
A new, fast procedure to calculate the transient characteristics of complex interconnection nets with nonlinear and capacitive loads is presented. The procedure may be used to determine pin-to-pin propagation delays of mass data as well as for the analysis of single critical traces on printed circuit boards. The voltages at the receivers are calculated from(More)
