Anotace

How to measure temperature (thermocouples, thermistors, optical fibres, radiation thermometers), pressure transducers (and strain gauges), displacement and deformation (inductive probes, optical, cross correlation using multiple camera systems), flowrate (nozzles, turbines, electromagnetic, ultrasound, Coriolis forces).

Material properties measurement: rheometry (rotational and capillary viscometers) and elastic biomaterials (constitutive equations of e.g. vascular tissues and plastic materials). Real instruments are demonstrated during lectures and of course at laboratory experiments.

How to transfer and record data in PC. Interfaces and software (Labview).

Data processing and basic statistics. Evaluation of standard deviation of predicted quantities knowing errors of individual measurements (e.g. evaluate error of viscosity knowing error of measured rotational speed and torque of rotational rheometer). Analysis of measuring chains.

Regression analysis of recorded data (identification of mathematical models). Linear regression (orthogonal polynomials, estimate of errors and reliability intervals of identified parameters). How to linearize some engineering correlations. Calibration of multiple thermocouples and pressure transducers. Nonlinear methods (deterministic: Marquardt Levenberg, simplex methods, and stochastic methods of artificial intelligence: SOMA-self organizing mitigation algorithm).

Time courses processing. Integral characteristics of time responses. Moments of responses (mean response time and variance). Relationship between stimulus and response functions (convolution, transfer function). Laplace and Fourier transform of convolution and correlation, power spectral density. Discrete transforms (Nyquist frequency). How to smooth out a noise (local regression, median smoothing, Fourier filtering).
