Today thanks to the wireless networking technologies and social networks, the inter-pretation of cyberspace has expanded. According to the three-layered structure of cyberspace, not only logical effects can be induced in this domain, e.g. by malwares, but physical and cognitive effects also appear in the physical and cyber-persona lay-ers, e.g. electronic jamming the wireless communications of network or influencing and manipulating users. This approach provides an opportunity to interpret cyberspace operations in a more complex way and to apply integrated technical and cognitive information capabilities that exploit each others effects. Accordingly, this study pre-sents an expanded interpretation of cyberspace, a novel and complex approach to cyberspace operations, as well as the information capabilities that can be used in these operations.

The paper discuses a possibility of application of the dynamic vivacity function defined in COS 137604 (STANAG 4115) at the interior ballistic process mathematical model conversion. At present time various technologies of powder grain surfacing are used mainly in case of powders used in assemblies of small-calibre cartridges. The grain surfacing can properly influence the shot process, change character of the powder grain burning which cannot be described by the burning theory according to geometrical rules. COS 137604 determines necessity of the dynamic vivacity function L evaluation for artillery powders only, but the way of its evaluation can be applied for arbitrary powder. It then allows the get results of the interior ballistic tasks solutions with higher accuracy as well as the choice of the suitable grain surfacing technology.

The article proposes a methodical approach to calculating the number of spare parts for weapon systems (WS) combat damage elimination and operability restoration based on criteria of minimization of spare parts cost, meeting the requirements of the spare parts, tools, supplies and materials, as well as timeliness of damaged WSs repair. The main points of the methodological approach (mathematical formalization of the task, basic calculation ratios, stages and order of calculation of spare parts stocks) are represented with a simplified scheme of the calculation of spare parts to ensure WS combat damage elimination and operability restoration. Probability of sufficiency and developed mathematical model for its calculation are used as a sufficiency indicator of spare parts to ensure WS combat damage elimination and operability restoration.

The paper presents a method of determining the dynamic parameters of multiple-rocket-launcher system mounted on the wheeled vehicle based on Newton's law of motion. The dynamic simulation was conducted and then the results were compared with the corre-sponding experimental data to verify the reliability of the model. The model was ap-plied in calculation and tested out on multiple-rocket-launcher system B?-21 (of Rus-sia). The theoretical model calculation results are relatively consistent with the meas-ured experimental data. The dependence of the launcher oscillation on the rate of fire was investigated, which determined the optimal rate of fire for each launcher. These results are used to evaluate the firing stability of the launcher when firing individual shots and firing bursts. This is an important theoretical basis which can be a reference for designers in the design process of improvement, manufacture, exploitation and use of a launcher mounted on the wheeled vehicle.

A novel beamforming technique that resembles the principle of interference is proposed for sonar arrays to suppress the side lobes while the main lobe is kept intact. It uses two window functions. The first one is a rectangular function that produces a primary beam pattern. A secondary new window function is derived and its beam pattern is steered such that the null or trough of the main lobe of the new window coincides with the peak or crest of the first side lobe of the rectangular window and so on to other major side lobes. Pattern multiplication was used to get a final beam pattern. The approach is simulated and verified through a sonar array with 24 hydrophone sensors.

The paper deals with the Dynamic Cone Penetrometer application which is intended to work as a vital means to support the bearing strength evaluation over the vast unpaved airport areas. Having identified fundamental drawbacks, the authors proposed some refinements in the original methodology. These predominantly respect the needs of airport operation services. Specifically, the model based on fuzzy logic and two tables, exceptionally suitable for day-to-day applications, are proposed and tested upon the extensive data set acquired at four airports over the last four years.

The article analyzes the impact of disruptive technologies on the evolutionary development of military architectural frameworks and concepts of warfare. It argues the need for a transition from the Network-Centric Warfare concept to the Data-Centric Operation theory and proposes a 4D-extensional representation of the combat space of weapon systems integrated into a single network. It is concluded that there is hardware redundancy in modern weapon systems and it is possible to use it as a network resource, the management of which provides additional opportunities for improving operational capabilities.

The paper presents the results of simulation tests of the entry of a floating transporter to a water obstacle. The simulation tests were performed with the use of LS Dyna program, based on the finite element method (FEM). The computational model was developed and used in the simulation of the manoeuvre of entering the water obstacle for the extreme conditions, which are described by NATO standards. For a model, as an example vehicle, the floating transporter PTS-M was used. The results of the application of the elaborated model confirmed the possibility to utilise the method to verify the behaviour of a vehicle in a very important and difficult problem from the point of view of vehicle safety conditions.

The paper investigates the individual and combined effects of disturbance factors including thrust misalignment, the offset of the centre of gravity and misalignment of the principal axes of inertia on falling point distribution of a type of unguided rocket (fin-stabilized rockets with single-stage solid-propellant rocket engines). The mathematical model used in the paper is developed from an available rocket motion model and solved for a representative rocket which is BM-21 rocket. The obtained results show dependencies of falling point deviation on disturbance parameters. These dependencies agree with the standard data given in the firing table; in addition, they are fuller and more insight ful than the previous research.
