The subject of the study in the article is the processes of analysis and exposure assessment of electromagnetic field on humans. The main goal is to optimize size of the exposure antenna systems, its electrical parameters and generated electromagnetic field (EMF) for different frequency range. Objectives: Electromagnetic field (EMF – Electromagnetic Fields) studies on living organisms are one of the important branches of biomedical research. Most of this type of research is conducted using dedicated exposures system with fixed and controlled EMF exposure conditions. The purpose of biomedical research is to determine the influence of electromagnetic fields on living organisms. For this purpose the exposure systems are designed. The main task of the exposure antenna system, is to produce the EMF with known and controlled parameters in a specific EMF area. Depending on the frequency and the component (E or H) of the electromagnetic field used, different types of systems are used. For low frequencies (for instance 50 Hz common frequency) and magnetic fields, Helmholtz solenoids or coils are used, and for electric fields - flat capacitors (E Field). For higher frequencies field E is used for systems with linear antennas or TEM lines. There are also dedicated probes for invasive tissue heating. Each solution has its advantages and limitations and usually there are no universal solutions for all cases. Results: For the generation of a low frequency magnetic field up to several hundred Hz, the Helmholtz solenoid or coil is generally used because of its relatively simple construction, the ability to obtain high intensity and good homogeneity of the field in a relatively large area relative to the dimensions of the whole system. The homogeneous field area can be determined analytically based on system geometry or measurement. Otherwise it looks for exposure system above few MHZ. To create a homogeneous EMF in the field of radio frequencies, the exposure systems - usually the TEM lines (Crawford compartment) or sometimes the GTEM are very likely to be used. In both cases there are frequency and spatial limitations - the homogeneous field is assumed to be maximally present. At 1/3 the height between the plates of the chamber and at the same time the maximum frequency of operation of the TEM chamber can be described by the approximate dependence of fmax [MHz] = 50 / d [m], resulting in a chamber operating at 1 GHz. The work piece does not exceed a height of about1.5 cmwith a diameter of about4 cm. Larger working areas, but at the same time, a lower homogeneity of the field can be obtained in the GTEM chamber - but at the same time the GTEM chamber has much larger geometric dimensions. Another way is to produce PEM with the parameters in open space - in the vicinity of the antenna. In this case, it is very important to select an antenna so that the expected homogeneous area can be obtained at an acceptable distance from the antenna - in order to maintain high EMF intensity and to reduce the radiation of the antenna beyond the desired area. This can be achieved by limiting the emission area by, for example, shielding or using EMF absorbers. In addition authors simulate novel ablation antenna for ablation treatment. Conclusions: Assessing the impact of EMF on biological objects is an interdisciplinary studies that requires the involvement of biological or medical specialists, as well as the EMF standard field and metrology specialist. In this work we have taken the subject of correct selection and description used in the experience of exposure systems. The authors presented the most commonly used EMF emitters in the low frequencies and microwave bands, as well as new model of the ablation treatment antenna.

Modern protection has layered structure. The main blow of high speed sub munitions takes the hard plate. They can be made of metal or high-strength double-layer panels. At a meeting with the panel the toe of bullet was destroyed. As a result of growing area of interaction between the bullet and the panel, there is a deflection and uncoupling ceramic bullet while destruction. When you hit the drummer in the obstacle created several types of wave perturbations that propagate with different velocities. These effects cause is a complex stress state structure, whose intensity decreases rapidly with time. The aim of the article is to investigate the interaction of high-striker with a protective barrier in the form of a set of hollow cylinders. The methods that are used: Improving personal armor protection can be achieved by applying the optimum combination of new materials and advanced structural and circuit design. Character penetration drummer an obstacle may change if the obstacle is to imagine a structure that consists of a set of hollow cylinders. Considered the process of interaction, of high-speed impactor, with a protective barrier, in the form of a set of hollow cylinders. In contact with the surface layer drummer obstacles by having an expanded, drummer enters the hollow cylinder, which closely hugs the side surface of the impactor, creating resistance to motion. When moving drummer in the cylinder is converting kinetic energy into energy impactor cylinder and deformation work to overcome friction. Thus, the energy of drummer extinguished intermediate layer and redistributed to the power frame inner layer. following results are obtained. The proposed a model to determine the depth of penetration drummer an obstacle in the form of a set of hollow cylinders. There are results of the calculations. It is proposed to further improve the protection of personal Armor achieve by applying the optimum combination of new materials and advanced structural and circuit design.

The subject of the study in the article is the analysis of methods for the synthesis of automatic control systems (ACS) for rolling stock with an asynchronous traction drive (ATD). The goal is assurance the quality of the processes dynamics, the accuracy of bringing objects to a specified point in the phase space, and minimizing energy costs for control processes in conditions of deterministic and random perturbations. The task is selection the method of optimal ACS synthesis, which allows providing the required indicators of ATD work quality. Analysis of the problems of optimal control of moving train traction drive showed that it is most promisingly to use the method of analytic construction of regulators by the criterion of generalized work (ACOR) for the synthesis of object management systems, which are described by systems of nonlinear differential equations. AKOR method allows to synthesize regulators that optimize control processes not only for deterministic, but also for random perturbations. However, the use of this method is possible for objects whose mathematical model is described by a system of differential equations in which control enters linearly. In connection with the fact that controls are non-linear in the ATD, to use the AKOR method, its adaptation was performed and expressions were obtained for the controls that determine the structure of the optimal regulator. Conclusions: an approach for the synthesis of the asynchronous traction drive ACS using the AKOR method is proposed. Adaptation of this method was carried out taking into account nonlinear controls.

The subject matter of the article is the processes of analysis and risk assessment of information and telecommunications networks. The aim is to reduce the potential losses caused by the risks of information and telecommunications network (ITN) functioning by taking timely risk management measures. The objectives are: classification of ITN risks, highlighting the main factors and causes of their occurrence; formation of a systematic presentation of risks to identify their manifestation and consequences; development of the method for assessing the influence of the risk and private risk on probable consequences; obtaining a quantitative risk assessment of ITN. The methods used are: system analysis of risks, method of cognitive maps, cause-and-effect analysis. The following results are obtained: classification of private risks of ITN according to the reasons and the factors of their occurrence is made; the negative consequences affecting the basic characteristics of the operation of ITN are defined; as a result, the structural system model of ITN risks is formed, in which the relationships between the elements of the main aspects of risk are shown; the method based on the theory of causal analysis is suggested in order to quantify the risk impact on ITN functioning. The risk model is based on the construction and analysis of probabilistic or fuzzy cognitive maps. Experts estimate the level of influence of private risks on the characteristics of the network in order to make decisions on risk management. The generalized structure of the cause-effect diagram of the risk factors, manifestation and consequences is developed; on ITN basis the method for quantifying the probability of risk consequences is suggested.

The suggested approach for quantitative assessment of ITN risk is based on the method of cause-and-effect analysis and enables taking into account both the factors causing it and probable consequences. The obtained results can be used to determine probable failures and losses in ITN functioning on the basis of the information about the degree of risk factors effects, risk events and consequences, and the cause-effect relationships between them. Thus, potential losses can be identified; measures to manage the risks of ITN functioning can be taken.

The increasing value of information protection is an important question in our fast-paced world. Especially acute is the question of copyright protection, which is against the backdrop of increasing the number of generated content, has become a real problem. The unauthorized use of foreign Intellectual Property of liability leads to great economic author`s losses. In order to minimize cases of data theft, steganography requires a large number of ways to conceal the fact of the information transfer (in contrast to cryptography, where you actually encrypted the message itself). Steganography is changing the image in a way that only the sender and the intended recipient is able to detect the message sent through it. It is invisible, and thus the detection is not easy. It is a better way of sending secret messages than encoded messages or cryptography as it does not attract attention to itself. Among the already proposed, existing steganography methods, such as: Digital prints (DP), steganography watermark (SW), hidden data (HD), in this work, attention is paid to watermarks (SW). SW implies the presence of the same labels for each container copy. In particular, the SW can be used to confirm the copyright. For example, when you recording video, you can intersperse information about recording time, in each frame, or the camcorder model, or name of your camcorder or the information about operator. If the footage gets into the hands of a rival company, you can try to use the watermark to confirm authorship of the record. If the key is kept secretly by the owner of the camera, then you can use the SW as a confirmation the authenticity of the photo and / or video images. Digital watermarks are used to protect the copyright or proprietary rights to the digital images, digitized photographs or other artwork. The main requirements that apply to this integrated data, are reliability and resistance to distortion. In modern systems, the formation of the digital watermark embedding the principle of label being a narrowband signal over a wide frequency range of the image to be marked. Digital watermarks have a small amount, however, subject to the above requirements for their integration using more sophisticated methods than to embed a message or header. This report is examined the possibility of using methods of steganography, which is based on the use of watermarks to protect and hide information to protect copyright.

Using exponential stochastic GERT models makes it possible to employ results obtained in an analytical form (functions, distribution densities) for comparative analysis and studies of more complex computer systems using mathematical methods.

The modern geoinformation systems (GIS) have been widely applied in Armed Forces for preparation and control of battle operations, for information providing of tactic activities, for improvement of topographic maps etc. In real situations during war activity the Geography information about situation on the terrain can be ofthen changed. So, in this cause the application of usual maps isn’t effective. Only the modern automated control systems can provide fast changing information documenting. The observation condition is one of the terrain features for providing information about enemy troops position and facilities. This feature helps to detemine the distance of sight between any observation points, the invisibility factors of terrain. It is depended on nature of relief plant cover, human settlements and other objects, also meteorological conditions, influencing on the visibility. As result of correct organization of observation, the obtained data help commander to estimate completely the military operation area and adopt a reasonable de?ision. In paper the observation conditions between two points of mountain terrain during battle operation have been investigated using GIS technology. The experiments for estimation of observation situation in mountain terrain has been carried out for one of the chosen region of the Caucasus. The visible and invisible areas have been revealed on the line of sight between two selected oversight points. The invisibility factors have been calculated and studied in depended on camera platform height. The visible and invisivle areas are determined under 0-180° angle in range 17941.16 m. The height profile between observations points and the digital heights model of investigated terrain have been constructed and analysed. At the various heights of camera observation platform the 3D heights models of the visible and invisivle areas have been constructed The invisibility factors between two delected viewpoints have been calculated. It is determined that if the heght of camera platform is increased above-ground level then the invisible area is decreased. ArcGIS software has been used for development and calculation measured results.

The subject of the article is an improved way to scale flexible methodology of software development. The goal is to reduce the potential losses caused by the security risks of software development and operation at most stages of its life cycle. Objectives: analysis of existing methodologies and approaches to software development, exploring the possibilities for scaling methodologies within individual projects, improving the overall design of the software development cycle, developing a software development management framework for both the individual project and the development organization as a whole, developing practical Recommendations to improve the security of software at various stages of the life cycle. The methods that are used: system analysis of risks, cause-and-effect analysis. The following results are obtained. The analysis of existing flexible software development methodologies has been carried out, prospective directions and approaches of this industry have been determined, and the opportunities for scaling flexible methodologies have been identified. The scheme of the life cycle of software development is improved, the distinctive feature of which is the introduction of additional subsections and roles aimed at increasing the security of software. The structure of software development management is improved, which differs from the known ones taking into account the security risks in the development process. Practical recommendations for using an improved method of scaling a flexible methodology have been developed. Conclusions. The implementation of the proposed improved method of scaling the existing software development methodology differs from those known by the inclusion and use of additional security specialists in the development team. This may entail some slowdown in code execution and an increase in the number of detected defects (bugs) during alpha testing, and, therefore, an increase in the life time of bugs. However, in the future, these local impairments can achieve a better end result (improving the safety of the developed software) and provide both rapid growth of functionality and an acceptable level of service quality. And this, in turn, will be an attractive motive for further cooperation between the customer and the developer.
