This article examines the sensitivity of the fiber-optic radiation scatterer to temperature changes. The scattering structure inside the optical fiber was obtained using the catastrophic fuse effect of the optical fiber. Due to the destruction within the core, periodic microcavities of the bullet-shaped and ellipsoidal form were formed. To study the dependence, a special device was developed and assembled to check the sensitivity of diffusers to temperature changes. During the study, a graph of the reflected radiation power amplitude dependence on temperature. Thus, the temperature at the location of the diffuser with an accuracy of up to 2.5 ° C can be determined from the reflected radiation power amplitude.

In this paper, the motion control of robotic rigid two-link manipulator using an adaptive LQ-based computed-torque controller is studied in the presence of unknown parameters in the dynamic model. This controller consists of a linear quadratic computed-torque one, and an adaptive update rule for estimating the parameters. The linear quadratic regulator (LQR) presents an optimal solution to minimize the tracking error. The advantage of the adaptive mechanism in this controller is that the accuracy of a manipulator carrying unknown loads will improve with time because the adaptation rule continues getting feedback signal from the tracking error.

The article discusses the influence of environmental parameters on pulse response of grounding devices. When lightning current flows down, complex physicochemical processes occur in grounds, which result in change in grounding impedance compared to that measured at a frequency of 50 Hz. Change of pulse impedance of grounding devices affects the magnitude of overvoltages arising on protective devices. Based on the results of experimental research and computer modeling, the transient characteristics of grounding devices were determined and the degree of influence of ground parameters on them was analyzed.

Technology mapping for macroblocks is a problem of implementing subcircuits in a Boolean circuit with predesigned IP blocks, like multiplexers and arithmetic circuits. In this paper, we propose algorithms for identifying some special kinds of macroblocks in an arbitrary Boolean circuit using dynamic programming and structural approach. Our algorithms can identify n-input standard gates (and-gates, or-gates, xor-gates, nand-gates, nor-gates and xnor-gates) with a large input size n. Also multiplexers and multiplexer buses can be identified using our algorithms.Proposed algorithms were implemented in a C++ programming language. It can identify and substitute specified macroblocks into a Boolean circuit represented in Verilog HDL format. Algorithms were tested on benchmarks from ICCAD- 2013 contest, where similar problem was introduced, and ISCAS- 85 benchmarks were also used to test our algorithms.

Type of scientific results and text data are divided into corresponding classes, which are based on hypothetical user needs. The classes indicate the type of a scientific result in article. The proposed approach involves the determination of meaningful collocations for scientific article. Topic modeling is applied to the received collocation sets from the text of an article abstract. The topics (classes) obtained show the relationship between a scientific article and the type of scientific result.

Carbon nanotubes are considered as one of the best candidates to be used as an emission layer in various applications. There are some drawbacks, which limit the wide use of CNT as field emitters. Mainly, it is a non-uniformity of the tips and degradation of emission current due to the nanotubes burning. In this work, we show the simple and cheap method of highly effective CNT cathodes fabrication. Single-walled CNT are located horizontally on the Si pillars made by Bosch process and demonstrate low field emission (emission starts at 100 V with an anode-cathode distance of 3 µm) and sufficient current densities as large as 8.5 A/cm2 at 200 V bias (2000 µm2 emitting area). Additionally, the comparison with vertically aligned the CNT cathodes is shown.

Article deals with calculation of the thermal load of the amplifier elements. The use of uncontrolled power supplies entails huge losses power allocated to the elements of the amplifier, which requires optimization. The efficiency of the amplifier is also unstable and lies in the range from 15 to 67%. The use of controlled power sources allowed to significantly reduce the power allocated to the elements of the amplifier (2 – 7 times). Also, the efficiency of the amplifier becomes approximately constant and is about 75%. The maximum thermal power dissipation in all modes is 1304 watts for the whole amplifier, including for each module 186 watts. To increase the reliability of the device, we select the safety factor for the power dissipation 3 and calculate the efficiency of the heat removal and recycling system at a thermal power of 600 W.

Nanoporous aluminum oxide membranes (NPAOM), obtained by a two-stage anodizing process, was an ideal material for creating nanostructures on its basis with given structural parameters and properties. NPAOM were used to create polymer nanostructures, non-interwoven carbon nanotubes, nanorods and nanowires of various materials, such as metals, oxides, etc. due to the structural features and physicochemical properties of NAOM, such as high chemical resistance, which increases with annealing temperature. Atomic Force Microscopy has been used as an ideal method for studying structural features of aluminum oxide nanoporous membranes as dielectric material with unique properties.
