  • ST-segment offset algorithm

    Article desribes the change in the ST-segment offset of the electrocardiagramm according to the variaty effects like fluctuations, respiration, additive noises, and heart rate deviation. Authors proposes to identify the ST-segment location in already synthesised ECG signal, adding an offset with consecutive nonlinear interpolation using National Instruments LabVIEW BioMedical Toolkit

    Keywords: Electrocardiogram, ST-segment, synthesized ECG, elevation, depression, heart rate, T-tooth, isoline, smoothing, interpolation

  • About the design of three-layer of reinforced concrete floor slabs

    The article presents suggestions for the design of three-layer floor slabs: two extreme layers made from ordinary concretes and one middle layer of lightweight. In the article method of determining the reduced cross section structures is given. It is shown that the most appropriate to use the ratio of secant modulus of deformation of concrete, also given appropriate calculation formulas.

    Keywords: three-layer plate, outermost layer, middle layer, the reduced cross section, the secant modulus of deformation, the level of loading, the calculated dependence
