Abstract
Supporting rod insulation is intended for insulating and fastening cathode parts of electrical installations at electric power substations. The insulation is set at outdoor switchgear of substations as a part of the main switchgear equipment. During the operation, it is exposed to external atmospheric influences, mechanic and dynamic loads. Timely replacing supporting rod insulation significantly increases the reliability of the main substation equipment at electric power substations. There was considering a question about improving the reliability at transformer and traction substations, providing internal and external conditions affected the destruction of supporting rod porcelain insulation. It was determined that an important negative part of supporting rod porcelain insulation damage is sharp swings of ambient temperature, especially swinging values after 0 ºC. A model is suggested for applying a supporting rod porcelain insulator as an insulating body in the ellipse form. It was described the suggested device work. The temperature gradient was taken into account, which shows the intensity of the temperature changing, is a vector directed towards the increasing temperature. There is an equation of a temperature field, which describes a thermal state of the body and determines a degree of its heating. There is an analyzing interacting ratio of values of circle axis and oval from larger to smaller in the spatial positioning in power loads, comparing a section form. The calculation determined a post insulator in the ellipse form should be set in the way where the long axis will be compatible in the gradient direction of temperature for decreasing influences of heating to the minimal axis of the insulator.

Abstract
In the process of transporting the tank to the place of operation, as well as during installation and repair work, the formation of mechanical defects on the body, such as a “dent”, of various sizes, shapes and locations relative to structural elements and technological fittings is possible. Defects of this type are stress concentrators, which may be the key to premature equipment failure due to its failure. The current regulatory documentation in the field of assessing the technical condition and strength analysis of capacitive equipment has established the necessary set of work to assess the negative impact of defects such as a “dent” on the normal operation of the vessel. However, in most cases, normative documents presuppose types of work aimed directly at identifying the geometrical dimensions of the dent and conducting non-destructive testing of the areas closest to it in order to identify unacceptable defects and unacceptable thinning zones, as well as strength calculation with a defect. According to these parameters, the so-called “admissibility” or “inadmissibility” of the detected dent is evaluated. In this paper, we study the relationship between the impact of a dent with certain geometric dimensions on the body of the technological tank on its stress-deformed state, considering the location of the technological fittings, and constructive solutions are developed to reduce the numerical values of maximum stresses.

Abstract
The research of influence of long quasistatic loading on characteristics of resistance to deformations and destruction of elements of vessels and devices, is of great interest to the solution of problems of control and forecasting of their technical condition. In order to detect changes in the mechanical characteristics of 09G2S steel and changes in the structure of the material under the influence of quasistatic loading, destructive tests of the studied samples in an initial state and after establishment of extrema of tension of constant magnetic field have been carried out. It is established that long influence of quasistatic loading in the considered conditions leads to change of a condition of steel 09G2S which causes reduction of characteristics of plasticity (S) and energy of destruction and increase in resistance to plastic deformations (ay
, ctts) what, in turn, can lead to a reduction temporary resource. The received results have allowed to develop the equation of assessment of a resource of the shell designs operated in the conditions of quasistatic loading, based on settlement and experimental dependence of a ratio of mechanical characteristics (cry/eTS) of steel 09G2S from duration of quasistatic loading.

Published: May 2020

Abstract
The developed device refers to analog low-pass filtering circuits and works as Butterworth-type broadband active RC filter. This filter can be used in devices for the human cardiovascular system diagnostic purposes, providing an opportunity to assess the state of the cardiovascular system. Such approach is based on the analysis of cardiointervalogram spectral power and can be implemented in biofeedback systems that use the current values of this power to generate feedback signals. The filter consists of second-order active bandpass filter blocks, connected together in series. Implemented schematic provides simultaneous tuning of the resonant frequency and the quality factor of the band-pass filter. This feature allowing to adjust the bandwidth while maintaining the center frequency and tuning the center frequency while maintaining the constancy of the band. The selection of bandpass filter tuning mode is made by selecting the appropriate adjustable components.

Published: May 2020

Abstract
In modern technological processes, a large role is played by measurements of technical parameters. The total number of industrial enterprises is constantly monitored by regulatory authorities for the use of water resources. Mostly it was not possible to measure most of the existing pressure-free flows recently, but with the advent of equipment on the metrology market that could measure the speed and level at the same time, the situation changed radically. It makes sense to consider in detail two measurement methods that are currently used in more than 90 % of cases – the acoustic (non-contact) method and the two-channel Doppler method which metrological standards of these methods were compared.

Published: May 2020

Abstract
Bioimpendance analysis allows to identify various pathologies, diagnose diseases in the early stages and determine the tactics of outpatient treatment for patients. It is most widely used in clinical practice. The article presents a structural diagram of the developed automated bioimpedance analyzer. The functional and metrological analysis of the hardware allowed to identify and systematize the causes of the methodological and subjective errors of the measurement results. To reduce the measurement error, a current source circuit, which allows the hardware to reduce leakage currents, is proposed. Bioimpedance measurement using an automated bioimpedance analyzer is performed at a frequency of 100 Hz to 2.5 MHz with a basic relative error of 0.1%.
Determine the effect of distortion of Mercator chart, Gnomonic chart on maritime safety and method of navigation when using Gnomonic chart
Authors: Nguyen T D 
Published: May 2020

Abstract
Nautical charts are an important tool to support safe navigation at sea. Several projections have been studied to develop charts for various maritime applications. Among them, the only Mercator projection satisfies the requirements of a nautical chart. However, the disadvantage of Mercator projection is the distortion that increases gradually to both poles. Therefore, Gnomonic charts are used to replace Mercator charts for navigation in some areas. However, the Gnomonic chart does not satisfy the basic requirements of a nautical chart, not built by an equiangular projection and the rhumb line is the curve on the chart. For building the nautical charts, the article will study the theoretical and practical basis of using Gnomonic projection instead of Mercator projection in determining the limit that the distortion of the Mercator projection affects the safe navigation, the conditions which the distortion of a Gnomonic projection has an influence on the safety of navigation in the allowable limits and finally determining the conditions and providing a method of navigation when using the Gnomonic chart instead of the Mercator chart.

Published: May 2020

Abstract

Background: Studies of PM2.5 health effects are influenced by the spatiotemporal coverage and accuracy of exposure estimates. The use of satellite remote sensing data such as aerosol optical depth (AOD) in PM2.5 exposure modeling has increased recently in the US and elsewhere in the world. However, few studies have addressed this issue in southern California due to challenges with reflective surfaces and complex terrain.

Methods: We examined the factors affecting the associations with satellite AOD using a two-stage spatial statistical model. The first stage estimated the temporal PM2.5/AOD relationships using a linear mixed effects model at 1 km resolution. The second stage accounted for spatial variation using geographically weighted regression. Goodness of fit for the final model was evaluated by comparing the daily PM2.5 concentrations generated by cross-validation (CV) with observations. These methods were applied to a region of southern California spanning from Los Angeles to San Diego.

Results: Mean predicted PM2.5 concentration for the study domain was 8.84 µg m−3. Linear regression between CV predicted PM2.5 concentrations and observations had an R
2 of 0.80 and RMSE 2.25 µg m−3. The ratio of PM2.5 to PM10 proved an important variable in modifying the AOD/PM2.5 relationship (β = 14.79, p ≤ 0.001). Including this ratio improved model performance significantly (a 0.10 increase in CV R
2 and a 0.56 µg m−3 decrease in CV RMSE).

Discussion: Utilizing the high-resolution MAIAC AOD, fine-resolution PM2.5 concentrations can be estimated where measurements are sparse. This study adds to the current literature using remote sensing data to achieve better exposure data in the understudied region of Southern California. Overall, we demonstrate the usefulness of MAIAC AOD and the importance of considering coarser particles in dust prone areas.

Published: May 2020

Abstract
Ajman is the smallest emirate in the UAE. Changes in the feature of urban areas in Ajman started in 1980 with the petrodollar economy. The upsurge of the global economy led to the construction of new buildings. Many mosques were built during the last few years in Ajman. The design of the mosques is distinctive in many aspects exhibiting differences in architectural style and form. Although there are some general rules and specifications for the new mosques suggested by the General Authority of Islamic Affairs & Awqaf (GAIA), nevertheless, it is not fully pursued. Therefore, it is important to address the issues of unity and identity through the physical image. According to our research, there are some purely modern mosques; others are a combination of traditional and modern styles. This paper will evaluate the different types of mosques that were built recently in Ajman. Similarities and differences between the various mosques will be analyzed and highlighted. The research was based on primary data conducted during the fieldwork in addition to drawings obtained from the GAIA. Despite the trend towards having diverse mosque designs, this study reveals that there is still a kind of unity among the new mosques.

Abstract
Shop house is one of the urban mix-use typologies that unites both commercial and housing function in one building. This type has been built since 900 BC, still and tends to be built more and more, particularly in Medan, Indonesia. This paper aims to describe how people perceived and adapted to the house of limited view, daylight, natural ventilation, and without a courtyard. The research took place in three shop houses corridors in Medan, namely Jamin Ginting, Setia Budi, and Sutomo Corridors. The study used a mix of qualitative and quantitative methods. The data of residents’ perception was collected through an evaluation-statement in five points Likert scale. The way people adapted the house was identified by analyzing the questionnaire by using descriptive statistic. The overall analysis was carried out through qualitative approach, that explaining the phenomenon and all relevant variables. The investigation found that respectively the community was satisfied with their house, especially the commercial area, as the needs they prioritized above a house. As a consequence, they adapted to the other rooms of limited view, natural ventilation, and dimension. However, while the residents in Sutomo Corridor had no wish of another house, the Jamin Ginting and Setiabudi Corridors’ occupants still dreamed of a more spacious landed house with courtyard.
