Authors: Klochkov S V , Minkin A N , Masaev S N , Krekhov A A
Published: May 2020

The paper focuses on the description of the characteristics of the upgrade heat flux sensor, as well as the consideration of various models of its application to identify the source of combustion. The device uses a photovoltaic cell used to determine the thermal radiation intensity. The value thus defined is subsequently digitized and applied to determine the location of the radiation source. Among other things, this enables to use the device for finding the fire coordinates in order to extinguish it effectively using robotized fire complex. It is proposed to upgrade the device, which is to extend the temperature range of operation, and also to increase the speed and number of detectors in the line. The paper also provides a structural diagram of the functional sensor elements. A patent has been received for an improved device. Since the photovoltaic cell of a new sample with improved properties is used in the device, the article also provides an analysis of its characteristics, influence curves of the intensity of the heat radiation source on distance, as well as lines of constant signal strength. The data obtained were used to create three types of fire detection models, depending on the geometric parameters of the protected premises and the location of the combustible content source.

Published: May 2020

An important stage in conditioning of water before its supply is the use of coagulants, with polyaluminium chloride being one of such agents. Active application of this coagulant began late last century, and its global output has been consistently growing since. The purpose of the work was to create a new standart because of the need to ensure a uniform assessment of the quality of the proposed coagulants. The necessity of unification in the field of quality control processes of coagulants is shown. General requirements for quality control of aluminum polyoxychloride are formulated. In particular, the standard contains universal methods to determine impurities and main quality parameters (basic capacity, contents of aluminium oxide and chloride ions) in polyaluminium chloride; regulate pH, residual aluminium, chlorides and heavy metal ions for the whole concentration range of the active ingredient in the agent (i.e. the standard covers both dry and liquid products); avoid use of low-quality raw materials (including aluminium scrap) in the production of polyaluminium chloride; characterise high- and low-basic products (given a non-linear change in properties at different concentrations); regulate frequency of and conditions for checking polyaluminium chloride against declared parameters.

Published: May 2020

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.

Authors: Rubtsov A V , Kulakov P A , Mukhametzyanov Z R , Bayazitov M I , Farshatov A R
Published: May 2020

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.

Published: May 2020

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

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.

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

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.
Estimating PM2.5 in Southern California using satellite data: factors that affect model performance
Authors: Stowell Jennifer D , Bi Jianzhao , Al-Hamdan Mohammad Z , Lee Hyung Joo , Lee Sang-Mi , Freedman Frank , Kinney Patrick L , Liu Yang
Published: May 2020

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.

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.

The purpose of this study is to examine the capabilities of using plastic bottle waste (PET) in architecture. The controversy of using a plastic bottle in this world brings up the idea of how efficient this material could be but at the same time how this material could rise the environmental problems. Therefore, we need to think better waste management for PET by promoting the capabilities of PET specifically in architecture. By using the theory of Cradle to Cradle to produce a sustainable material product by Braungart and McDonough, we can improve the value of PET’s functional life residue. Research on PET’s capabilities was based on several case studies where PET was used in many different types of applications, but the focus was on physical uses of the material. Some of PET utilizations are in the form of furniture, wall, brick, and structure. The conclusion is that every application must not be applied all together at once in one design. On the other hand, we can use it as an element in architecture, because every application needs to stand with another material other than PET itselves. These utilizations can enhance the life span of PET material after its functional cycle ended.

Medan is one of the major cities in Indonesia, with a population of 2,210,624 people. The high number of population causes more and more people to purchase residential housings. The high costs of these housings have prompted people to use the public housing loan (PHL) program from banks such as BCA, BRI, BNI, Bank Mandiri, Bank Permata, Bank Cimb Niaga, Bank Danamon, Bank Panin, Bank Sumut, and BTN. Details of the PHL financing program are usually known by the customers once they have problems. Bank information disclosure is a defining factor for customers to choose their preferred bank. Increasing the PHL financing program will make the banking sector grow, which will ultimately affect the economic development of Medan. However, there are still many banks who have not implemented the principle of transparency. This will decrease customer trust to use banking products. This research uses the normative juridical method. The results indicate that the principle of transparency and disclosure of bank information in PHL financing program is still not optimal. This will greatly affect sustainable development in Medan because the banking sector relies heavily on customer investments and trust.
