MATHEMATICAL MODELLING OF BLOOD FLOW
The paper presents the two-phase model to describe blood flow in large and in small blood vessels. Based on this model the study gives an explanation for long known features (effects) of blood flow in the vessels: dependence of the hematocrit (packed cell volume) on the diameter of the vessel,...

INFLUENCE OF NON-UNIFORM LATERAL INTERFACE DEFECTS DISTRIBUTION TO THE CURRENT-VOLTAGE CHARACTERISTIC OF MOSFET
In the paper the influence of the defect lateral distribution on drain current in nanometer MOSFET is considered.The simulation results show the drain current depends on lateral as well as longitudinal distribution of interface defects. Maximal change of the drain current is seen at localisation of...
