Data security is one of the main tasks solved by IT departments of companies. Moreover, it is not only about preventing the leakage of corporate information, reducing the volume of parasitic traffic and repelling attacks on the company's resources, but also about optimizing the system as a whole. It is virtually impossible to find a universal solution in this matter: the heterogeneity of the spheres of activity and the structures of organizations translates the task into a category that requires an individual approach. The article deals with the main information threats of corporate systems, as well as methods of protection against common threats and attacks on information systems of the enterprise, estimated the cost of specific solutions.

It is shown that thermal flow sensors are characterized by high structural and technological compatibility with biomedical equipment and, compared to other types of flow sensors, they most fully meet the requirements for this equipment. The developed signal converters fully meet the requirements for modern biomedical equipment and energy-saving low-voltage electronics (unipolar 3V power supply), provide a negligible thermal effect on the flow environment and are implemented on the latest element base - high-precision CMOS railto-rail operational amplifiers, bidirectional multiplexers of the type ADG, ADuC type microconverters, powerful D-MOS HEX FET transistors, etc

The article presents and provides materials for the analysis of the main distributed information. Influences and information threats in microcontroller systems that work as part of electronic systems of modern electronic devices and automation. The main widespread information threats and the ways of intervention of informational influences are determined. An assessment of their impact and short-term ways of minimizing them are provided. The main basic types of widespread cyberthreats and channels directly affect the stability and safety of the microprograms of the MK itself and, as a result, the operation of the electronic devices in which this MK is included. The channels of information threats for microcontrollers are their weak points, which need to be studied in order to further eliminate and minimize them. This made it possible to assess the main vulnerabilities in the MK architecture and, in the future, to plan an action plan to minimize and neutralize the main threats and information influences in the MK for the stable and safe functioning of electronic systems based on microcontrollers.

In given article, we investigate medical images and develop an intelligent system for identification of the disease on their basis. The paper proposes an approach to finding the affected tissue areas in medical images. To find them, a mask was extracted for training a neural network. Mask extraction was carried out using annotations, where polygons with affected tissues were identified. The studied objects were assigned to different classifications of morbidity.

The features and functionality of processing of the one – dimensional (vector) arrays of numerical data by the use of computational method with the formation of difference slices are considered. At the base of this method SM – transformation principles are used. The allocation of the minimum of non-zero component of the element array in this case is considered as the formation of the internal processing threshold and is the basic procedure of SM - transformation in each processing cycle. As a result, not only the operation of parallel multi-operand summation of the number array is realized, but also there is an opportunity to restore the initial number array, as well as to sort its elements according to the growth of their numerical values and to form their ranks. Two matrices of binary masks are used for this, that are formed during the processing, which are the matrices of zero and positive criterion, respectively, inherent in the elements of the current difference slices. In addition, in each processing cycle the internal thresholds form a vector of internal thresholds as a result, which takes part in restoring the elements of the initial array. The it is presented in the article the basic relations of difference slice processing, and the examples that confirm their validity using data presented in the form of a table.
