This paper talks about new micro-virtualization technology which aimed to secure computers from undefeateble attacks and stop the malware.
Keywords: security, microvisor, micro-virtualization, malware.
Summary: The paper considers a variety of approaches to the adaptive testing. It points out the criteria of adaptive testing, then develops model of complex adaptive testing based on those criteria.
Keywords: adaptive testing, the criteria of adaptive testing, complex adaptive testing, model of complex adaptive testing.
Summary: The article studies a Systems Dynamics model for capturing the main interactions involved in the subprime mortgage crisis. The model provides two subsystems interconnection that related to each other relatively banking asset flow and house market. The differential equations are analyzed and simulated using Vensim PLE simulation software, which brings to the discussion of results.
Key words: system dynamics, financial crisis, subprime mortgage crisis.
Summary: This work describes the problem of map contraction and a robot localization using sensor data and data from a group of other robots. This methodology is called SLAM or CML, Simultaneous Localization and Mapping or Concurrent Mapping and Localization, respectively.
SLAM solves problems connected with building a map of an unknown environment by a mobile robot while at the same time navigating the environment using the map.
SLAM comprises of multiple parts: landmark extraction, data association, state estimation, state update and landmark update. Each part can be performed in different ways. As the robot has sensors on one height from the ground, we will get 2D map [1].
Key words: SLAM, computer simulation, robot.
Abstract: The basic condition for obtaining granular product with layered structure is the active involvement of the entire surface of the granular material located in the fluidized bed with dehydration composite liquid systems containing more than 50% of the solvent, which can not be achieved with traditional bubbling mode can not effectively solve this problem. Therefore, the use of spray and pulsating regime fluidization of granular material circulation directed to intensify the process by creating three dimensional mixing and prevent the formation of dead zones is relevant.
Keywords: fluidized bed, hydrodynamics, jet-pulsating mode, granulation.
Summary. In article, on the basis of the analysis of the existing light sources used in industrial, civil and in household rooms, characteristics of modern luminescent lamps of low pressure with electronic input-regulate devices are investigated.
Key words: light, illumination, fluorescent lamps, man, ultrasound.
Summary: This article is dedicated to the development of the method for creating summarization of the text document. Approaches were taking into account such as the generation of summarization.
Key words: summarization, abstract-based summarization, abstract summary.
Summary: The paper applies information technology and mathematical modeling to examine the epidemiological characteristics of a large-scale problem, known as antimicrobial resistance. It describes a mathematical model constructed to emulate the process of spread of resistant bacteria in a hospital environment using system dynamics. The model includes several key parameters such as the contact rate between the members of different observed groups, the rate of treatment with antibiotic drugs and others.
Key words: system dynamics, computer simulation, antimicrobial resistance, antibiotic resistance.
Summary: In the short-wave area of a spectral characteristic of solar cells (SС) where the frontal layer of structure is responsible, sharper recession of sensitivity is observed. In article results of research of process of diffusion of impurity are given to single-crystal silicon through oxide coverings of SiOx and their influence on transformation of characteristics of structures of SС.
Key words: solar cells, short-wave part, protecting cover, effective thickness, spectral characteristic.

Summary: This article analyzes the main methods for evaluating the quality of voice traffic in the network, the quality of the evaluation criteria of network traffic according to QoS and E-model. Comparison of subjective and objective methods of assessing the quality of the voice traffic. The research results were modeled and are illustrated in the example of the multi-network models. The influence of the technical characteristics of the network on the subjective assessment of the quality of voice traffic in the network. Based on studies conducted by the authors have shown that the QoS parameters have a significant influence on the quality of the voice traffic in the network
