The possibilities of optical capillaroscopy to determine microcirculatory disorders are considered. Methods for evaluating microcirculation by measuring the size of a pillar and its departments, as well as the speed of capillary blood flow, which may indicate a state of microcirculation in general are proposed. The physical model of the capillary is considered, as well as the classification of the stages of microcirculation disturbance, which is used to form a medical conclusion about the severity of hemodynamic disorders. Also, for the system of computer capillaroscopy, methods for calibrating and segmenting images of microvessels are proposed.
Method and algorithm of multidimensional information scaling of the characteristics features based on the results of the theory of perturbation of pseudo-inverse and projective matrices and solutions of systems of linear algebraic equations is proposed. The algorithm of a piecewise-hyperplane clusterization with the verification of a given criterion for the effectiveness of the proposed method of the clusterization is developed. An example of using the method of scaling characteristic features for recognizing the fingerspelling alphabet of the sign language is given.
It is well known that the application of the weight redundancy in self-calibrating DAC enables to lower considerably, the requirements regarding the accuracy of digits weight formation, particularly in multidigit code-current converters and the idea of laser adjustment of the resistor matrices nominals. It is also known, that the construction of ADC of the bit-wise balancing on the base of such DAC additionally enables to increase (by an order or more) the operation speed as a result of a considerable reduction of the balancing cycle duration.
