Разумный человек приспосабливается к миру; неразумный - упорно пытается приспособить мир к себе. Поэтому прогресс зависит от неразумных людей.

Information security of automated systems, embedded solutions, virtual and cloud environments

Livshits I.I., Zaitseva A.A.  Security problems of the cloud component of information technologies

An attempt is made to investigate and assess the opportunity of ensuring the specified security level for present-day cloud services. The paper cites various opinions of Russian and foreign experts on a wide range of information security issues for both individual components and cloud services as a whole. It proposes to introduce formal techniques for assessing the degree of correspondence between the existing and future components of cloud service security systems. An approach is proposed ensuing from the earlier developed hybrid methodology using a number of formal procedures underlain by two systems of criteria: the assessment of the degree of compliance of ISO/IEC 27001 Series management systems and the assessment of functional security requirements based on IEC 61508 Series and ISO/IEC 15408.

Keywords: information technology, information security, audit, compliance assessment, protection tools.

Keywords: additive technologies, classifier, flexible production system.

Zinyaev V.V., Balashov S.M.  Quality assurance of component parts manufacturing for aerodynamic models using additive SLM technology

The paper discusses the additive selective laser melting (SLM) technology as a part of an integrated automated design and fabrication system for aerodynamic aircraft models. Standard component parts most attractive for using SLM technology are determined. The paper shows that the manufacture quality and process efficiency depend on the process unit throughput and the rational parts positioning over the working area.

Keywords: additive technologies, selective laser metals melting, SLM technology, design and manufacturing of aerodynamic models.

Degtyarev A.V., Romanyuta D.A., Grishin P.R., Morozov V.N.  Investigation of physical-mechanical properties of elements hull structures with the example of ship plates under additive production conditions

The paper evaluates the parameters of additive technologies application in present-day shipbuilding industry by analyzing physical-mechanical properties of based on carbon chemistry-based 3D printing materials, such as SBS plastic, ABS, PLA, HIPS, and PETG. The materials were investigated under different thicknesses and filling structures. Ship plates were selected as the research target due to their prevalence in ship hull production. The research aimed at revealing physical-mechanical patterns of marine articles formation by additive production under semi-scale testing conditions. Physical-mechanical properties were evaluated by means of tension and bend tests of plate samples with the help of a special tensile machine supplemented with special gear. Based on the test data, the recommendations were made on the application of additive technologies in shipbuilding, and the applicability of 3D printing materials in hull manufacturing was examined.

Keywords: 3D printing, additive technologies, shipbuilding, physical-mechanical properties, structural strength, ship hull structures, ship plates, composite.
