The article to contain results of the researches, allowing to raise level of protection of the automated and intellectual information systems enterprises (AIS). The article discusses the use of discrete procedures to detect threats DoS (DDoS) attacks for information resources.
Active application of new progressive methods of binding materials treatment allows to solve ecological alongside with pure technological and economic problems. Mechanical activation and modification, as the most effective representatives of such methods, lead to substantial increase of binders quality. The use of such methods allows to control structure formation processes while forming polymeric...
The problem of the automobile course stability is considered. The change of the car steerability based on the analysis of non linear bicycl model is analyzed. Generalized dependence determining “the steerability curve” is obtained. Conditions which caused the loss of stability with increasing speed while moving within the constant radius circle regarding the bifurcation set are analyzed.
The analysis of visualization in the system of the automated planning of constructions is resulted in the article. The new going is offered near realization of algorithms of visualization of results of calculations within the framework of complex «MIRELA +».
The results of mathematical simulation of dynamic processes of opening and closing electro-pneumatic valve and optimization of geometrical parameters of brake device are presented.
The article describes the software model of the system designing of the electronic courses (EC) with minimal impact of the subjective factor (CAD EC). IT uses ontologies of subject domain (SD). Ontology of subject of discipline (SDi) built on basis of SD. Ontology of subject of discipline includes descriptions of concepts, examples, laboratory works, tests. CAD EC converts reference books EC in the...
In the article the impact of the structure of pipeline transportation systems on the efficiency of their operation is examined. It is shown that, depending on the assumed structure, transport systems can be characterized by different performance characteristics. It is established that the structure of the system influences the development of the aging process and decrease system performance. Recommendations...
The technology of producing gear-wheels by stamping with division of operations of rough and finishing forming is examined. A solution for stress and deforming force of calibration of gear teeth in a stamp with cone-shaped punch is found.
There grounded the frequency range choice in the system of the operation reliability of the technical systems based on the application of probabilistic – statistical method.
In the article the theoretical basis for calculating the productivity of the vehicle and determination of the rational distance whileorganizing the cargo transportation with the change of trailers is offered.
The problem of determination of expedience of the use of piezoelectric sensors in piezo actuators, connected with the scheme of DD-TR, is considered. The transitional characteristics and amplitude of output signal also is determinate.
The theoretical reasons of creation the reactive rotation disc engine on cascade pressure exchanger base (ERR CEP) have been stated. The particularities of ERR CEP working process in collation with wave disc engine on wave pressure exchanger base have been considered. It is in particular shown that cascade pressure exchange principles use allows vastly to increase the pressure of preliminary compression...
In this work the connected thermoelastic contact problem for an elastic half-space to which some area heat radiant is brought is considered. Applying a method of integral transformations of Fourier to system of the differential equations of thermoelasticity and a heat conduction equation, the problem is reduced to system of two two-dimensional integral equations for definition of thermoelastic normal...
