Elastohydrodynamic lubrication line contact in couple-stress elasticity
Authors: Su Jie , Song Hong-Xia , Ke Liao-Liang
Published: December 2020

By using the couple-stress elasticity theory, this article firstly analyzes the size-dependent elastohydrodynamic lubrication (EHL) line contact between a deformable half-plane and a rigid cylindrical punch. The size effect that emerged from the material microstructures is described by the characteristic material length. It is assumed that the viscosity and density of the lubricant vary with the fluid pressure. An iterative method is developed to deal with the flow rheology equation, film thickness equation, load balance equation and Reynolds equation at the same time. Then, distributions of fluid pressure, in-plane stress and film thickness are determined numerically at the lubricant contact surface. Influences of the size parameter, punch radius, resultant normal load and entraining velocity on the fluid pressure, in-plane stress and lubricant film thickness are discussed. The fluid pressure and film thickness predicted from the couple-stress elasticity theory present significant departures from the classical elasticity results. It is demonstrated that results for micro-/nano-scale EHL contact problems may be underestimated when the classical elasticity theory is employed.

Authors: González-Martín-Moro Julio , Porta Etessam Jesús , Pilo de la Fuente Belén , Fuentes Vega Irene , Contreras Inés
Published: December 2020

Introduction:

Migraine is one of the most common causes of transient visual loss. Optical coherence tomography angiography (OCTA) provides fast and non-invasive imaging of the retinal vessels. We report one case of monocular retinal oligemia demonstrated using OCTA during a migraine attack with aura.

Case description:

A 27-year-old man with a previous history of migraine with visual aura was seen in the emergency room due to acute left hemicranial pain with positive visual symptoms in his right eye. The patient reported a blue stain in his right eye. Optical coherence tomography angiography (OCT-A) showed an extensive area of hypoperfusion in the macular region of his right eye. Forty-eight hours later visual symptoms had improved and the OCT-A showed a significant reduction in the area of hypoperfusion. Seven days later the patient was asymptomatic and retinal perfusion had returned to normal values.

Conclusion:

Monocular involvement suggests that these retinal vascular changes are independent from cerebral vascular changes, supporting the hypothesis of selective retinal ganglion cell layer spreading depression as the possible cause of some cases of retinal migraine.

Published: December 2020

3D woven composites are considered as the ideal materials for subsea pressure shells owing to their exhibit excellent out-of-plane properties of delamination resistance and compressive damage resistance, which greatly improves the bearing capacity of the structure. This paper presents the influence of the radius-to-thickness ratio and the initial defects on the 3D woven composite spherical shells subjected to external hydrostatic pressure using the multi-scale finite element and theoretical methods. Two kinds of typical 3D woven structures, curved shallow-crossing linking 2.5D, and straight shallow-crossing linking 2.5D, are selected. The results show that the proposed multi-scale finite element method is capable of accurately predicting the strength and buckling behavior of 3D woven composite spherical shells under external hydrostatic pressure loadings, validated by the comparison of theoretical predictions. Furthermore, the fabric structures, radius-to-thickness ratio, and initial defects affect importantly the mechanical behavior of 3D woven composites pressure shells.
A Review of National Occupational Standards and the Role of Human Resource Development in their Implementation
Authors: Lee Andrew Sanghyun , Jacobs Ronald Lynn
Published: December 2020

This review of the literature focuses on an increasingly prevalent global phenomenon known as national occupational standards (NOSs). As the term suggests, NOSs present specific information describing the requirements for individuals’ qualifications to enter and perform successfully in a specific occupation. Many countries rely upon information from NOSs as part of their broader workforce development efforts. In spite of their prevalence, there remain critical questions about their eventual adoption by employers, a situation that HRD researchers could potentially help address based on the unique perspective of the HRD field. This paper seeks to review what is known about NOSs, to discuss the challenges related to their implementation at the organizational and national levels, and finally, to propose how HRD researchers, through their unique perspectives, might contribute to addressing the challenges most commonly encountered when implementing NOSs. It is expected that through this greater awareness, HRD professionals might be able to advance the effective use of this important global phenomenon.

Authors: McCarthy Claire M , Conlon Caroline , Kennelly Maria , Drew Richard , Stewart Stephen , Geary Michael P
Published: December 2020

We present the case of a healthy nulliparous woman who presented with persistent fever, proteinuria and elevated transaminases at 33 weeks’ gestation. Following initial treatment for suspected chorioamnionitis and potential pre-eclampsia, she had a caesarean section delivering a healthy male infant. However, on her third post-operative day, she developed neurological symptoms and accompanying severe sepsis, necessitating inotropic support and transfer to a higher level of care. A comprehensive work-up revealed herpes simplex Virus-2 (HSV-2) in serum and cerebrospinal fluid. Abdominal imaging was suggestive of accompanying hepatitis with micro-abscesses. This lady recovered well following intravenous acyclovir for 14 days. Her infant was not affected and was discharged home with his mother. Herpes simplex encephalitis and hepatitis associated with HSV-2 have been described three times previously in pregnancy. We delineate the diagnostic challenges that rare conditions such as this pose and emphasise the importance of multi-disciplinary care in managing complicated medical conditions in pregnancy.
Perceived Duration Depends Upon Target Detection in Rapid Serial Visual Presentation Sequence
Authors: Ichikawa Makoto , Miyoshi Masataka
Published: December 2020

It is well known that the perceived duration for a given time period decreases with the reduction of the number of perceived events. We examined whether target detection failures in viewing Rapid Serial Visual Presentation (RSVP) sequence, caused by attentional blink, affect this reduction of perceived duration. In two experiments, trials consisted of displays of two series of RSVP sequences; in the first sequence (the comparison), two, one, or no numerals were presented as targets embedded within the string of letters, while in the second sequence (the standard), only alphabetic letters were presented. In each trial, participants judged whether the duration of the comparison is perceived as longer than that of the standard (Experiment 1), or whether the number of frames in the comparison is perceived as more than that in the standard (Experiment 2). Results showed that perceived duration was inflated with target detection, but not with the increment of presented frames although number of perceived frames was inflated with both target detection and increment of presented frames. These results suggest that perceived duration in viewing RSVP sequences is determined by the cognitive load necessary to accomplish target detection rather than by the number of perceived frames.
Lightness in a Flash: Effect of Exposure Time on Lightness Perception
Authors: Kaneko Sae , Gilchrist Alan
Published: December 2020

A gray target can appear lighter or darker depending on its surrounding spatial context. We examined the effect of exposure time on three such examples (simultaneous lightness contrast, dungeon illusion, and the two-room arrangement), finding very different results with exposure time as brief as 15 ms: the simultaneous lightness contrast was much stronger, the effect of the dungeon illusion was reversed, and the lightness difference between the two isoluminant patches in the two-room arrangement disappeared. These suggest that local luminance ratios dominate lightness perception in a brief flash.

Published: December 2020

Rhabdomyolysis is an uncommon complication of the coronavirus disease 2019 (COVID-19) infection. Previous reports have described its management and treatment in medical units, but have not discussed confirmatory tests or differential diagnosis. We report a case of a 58 year-old male patient, who was admitted for COVID-19 pneumonia and subsequently developed severe weakness, inability to move limbs, acute renal failure, significantly elevated myoglobin and creatinine kinase, and was diagnosed with rhabdomyolysis. Continuous renal replacement therapy, the treatment modality of choice over hyperhydration due to ongoing mechanical ventilation, was effective in resolving symptoms. No direct viral invasion of muscles was noted on biopsy. Here, we describe his symptoms, electromyography, and muscular biopsy results, and further discuss the possible differential diagnoses. Neuromuscular symptoms related to COVID-19 require careful clinical analysis. In addition, detailed reports of patients’ course of illness and diagnoses will assist in improving care for affected patients.
Improvement in Hailey–Hailey disease with a combination of low-dose naltrexone and oral magnesium chloride: A case report
Authors: Lim Darosa , Belisle Annie , Davar Sandra
Published: December 2020

Hailey–Hailey disease is a rare autosomal dominant acantholytic disorder due to mutation in the ATP2C1 gene and presents with flaccid blisters in intertriginous regions. Its chronic and relapsing course may negatively impact patients’ quality of life. Multiple medical and interventional treatments have been described with various efficacy. Low-dose naltrexone and oral magnesium chloride represent emerging treatments. Sustained improvement in Hailey–Hailey disease has been reported with the former in case series, while others have shown variable results. Oral magnesium chloride has been reported in four patients with possible results after 2–4 weeks. Two recent cases suggest that the combination of both treatments may have a synergistic effect. Herein, we present a 63-year-old woman with long-standing and recurrent bilateral inguinal Hailey–Hailey disease who significantly improved with low-dose naltrexone and oral magnesium chloride, representing the third case described with this combination.

Authors: Onishi Ryota , Sano Keito , Shimada Tetsuya , Ishida Tamao , Takagi Shinsuke
Published: December 2020

Rh-doped titania nanosheet (Rh-TNS, Ti1.78Rh0.02□0.20O40.22− (□: vacant)) was synthesized. The adsorption behavior of Zn(II)TMPyP4+ (Zinc(II) 5,10,15,20-tetrakis(1-methylpyridinium-4-yl)porphyrin) on Rh-TNS was examined. According to the absorption and fluorescence measurements, the efficient fluorescence quenching of Zn(II)TMPyP4+ was observed on Rh-TNS, indicating the electron injection from excited Zn(II)TMPyP4+ to Rh-TNS. By irradiating monochromatic 450 nm light to Rh-TNS/Zn(II)TMPyP4+ complex under the presence of electron donor (ascorbic acid) in water, hydrogen production was observed. The quantum yield for hydrogen production was 5.0% under the optimized condition. The action spectra for hydrogen production well coincided with the absorption spectra of Zn(II)TMPyP4+. These results indicate that a dye-sensitized hydrogen production system where Rh-TNS was used as a host material, an electron acceptor and a catalyst, was established.
Multispectral radiometric temperature measurement algorithm for turbine blades based on moving narrow-band spectral windows
Authors: Zhao Yingze , Lv Jinguang , Zheng Kaifeng , Tao Jin , Qin Yuxin , Wang Weibiao , Wang Chao , Liang Jingqiu
Published: December 2020

This paper addresses the problem of inaccurate emissivity presets for multispectral temperature measurements of aero-engine turbine blades and proposes a narrow-band spectral window moving temperature inversion algorithm that does not rely on an assumed emissivity model. As the emissivity of the measured object changes slowly over the narrow spectral window, the temperature corresponding to the normalized spectral radiation intensity for each window in the set temperature range is calculated using the Mahalanobis distance coefficient. The temperature error is less than 1.33% relative to thermocouple measurements when using this algorithm to perform temperature inversion on the experimental spectrum curves for different types of alloy samples. Furthermore, a two-dimensional spectral temperature field measurement platform was built, and the surface temperature fields of alloy samples were reconstructed using the narrow-band spectral window moving algorithm. The proposed algorithm is shown to provide high-precision inversion of the temperature field without presetting the emissivity model, which gives a new processing concept for the application of infrared spectral temperature measurements.
Efficient nano-tweezers via a silver plasmonic bowtie notch with curved grooves
Authors: Li Zong-Sian , Lu Tsan-Wen , Huang Pin-Ruei , Lee Po-Tsung
Published: December 2020

Localized surface plasmon resonance (LSPR) with a sharp field gradient and extremely strong field intensity is very attractive for near-field optical nano-tweezers manipulating tiny bio-objects with sizes ranging from sub-10 nm to micrometers. To lower the power consumption of optical trapping and improve the accessibility of LSPR for the targets, we propose and study a plasmonic bowtie notch design with assisted periodic curved grooves. By generating and coupling extra surface plasmon polariton waves into the LSPR, the presented design herein can significantly reduce the required power consumption in experiments for stably trapping single and multiple polystyrene spheres. We believe the idea and results presented in this paper would be helpful in realizing highly efficient nano-tweezers in the plasmonic circuit on-chip.
URGENSI MAJLIS TAKLIM SEBAGAI WADAH SOSIALISASI PEMAHAMAN AL QUR’AN BAGI IBU-IBU
Authors: Akmaliyah Akmaliyah , Rosyid Ridho Mohammad
Published: December 2020

AbstrakSalah satu wadah pembelajaran informal, yaitu majlis taklim. Lembaga ini  mempunyai peran penting dalam membina dan meningkatkan kualitas umat dalam hal  akidah Islam. Melalui majlis taklim masyarakat dapat lebih mendalami, dan menjalankan ajaran agamanya tanpa terikat dengan persyaratan dan ketentuan seperti yang terjadi saat belajar di lembaga  formal. Majlis taklim adalah tempat pertama dalam sejarah Islam sebagai sarana sosialisasi Islam, pengembangan dan pemberdayaannya. Hingga saat ini majlis taklim tetap masih dijalankan, khususnya oleh ibu-ibu. Majlis taklim ibu-ibu banyak dilaksanakan di pedesaan, perkotaan, di  mesjid  bahkan dari rumah ke rumah. Maka pemahaman ayat-ayat dalam surat-surat pendek al Qur’an, pada khususnya, untyuk ibu-ibu di majlis taklim merupakan langkah strategis penyebaran nilai-nilai Islam. Metode pengkajian pemahaman ayat al Qur’an tersebut diawali dengan pengenalan bahasa Arab dasar, dilanjutkan dengan memami makna kosa kata bahasa Arab dalam ayat-ayat al Qur’an tersebut, sambil dijelaskan kandungan nilai-nilai di dalamnya.  Kegiatan ini dilakukan dengan teknik ceramah, penugasan dan dialog. Abstract One of the most widespread centers for informal learning among Islamic communities in Indonesia is majlis taklim. Considered an important and productive place for imbibing a sound Islamic creed, majlis taklim gives the community a chance to be able to carry out their religious teachings without terms and conditions of formal institutions. Developed and empowered since earlier Islam, it is the first of its kind in Islamic history to function as a means of socializing Islam. The present day majlis taklim is still being carried out especially by mothers. Mostly carried out in rural and suburban areas, in their mosques and private houses. A strategic step for spreading Islamic values among them is through learning al-Qur'an by memorizing and understanding its short verses; it begins with an introduction to basic Arabic, then its vocabularies and followed by understanding the meaning of the Qur’anic verses word by word side by side with the explanation of  the values contained in it. This activity has been carried out through simple lectures, assignment and dialogue techniques.
No-Greenery Line and Greenery-View Factor, New Architectural Design Tools
Authors:   Faculty of Architecture and Design, Norwegian University of Science and Technology, Trondheim, Norway, Matusiak Barbara Szybinska
Published: December 2020

The paper proposes a new tool for evaluation of the degree of visual contact with the outdoor greenery, the Greenery-View factor (GV), intended to be easy to grasp and simple to use. It starts with the construction of a No-greenery line (similar to the No-sky line) on the vertical section of the building with the neighbouring greenery included. No-greenery line divides the space into a part with the view to the greenery and the rest of the room from which the greenery is not visible. To find out the part of the floor area of the room from which the greenery can be seen, the section-point between the no-greenery line and the line representing the eye-level is projected down at the floor plan. The GV factor stands for the part of the floor area with the view to the greenery expressed as a percentage of the whole floor area of the room. The No-sky line and the No-greenery line can be used together by architects and urban planners as extremely simple and powerful couple of graphical tools. The paper discusses also how the GV factor could be implemented in the new European daylight standard EN-17037 Daylight in buildings (2018).

brief overview of a few neighbouring countries which have different legal regimes in water laws and conflicts. There were water transfer conflicting rules in some countries as against water as a right. The clash between environmental are human rights, constrains of market perspective are also discussed. The first part discussed about the codification of water laws as a right or privilege and products containing water, such as agricultural produce are subjected to trade disciplines and trade barriers. In the case of bulk transfers of fresh water, private contractual remedies and negotiations between the parties or remedies available in public international law were reviewed, rather than the remedies provided for in trade agreements disputes such as in NAFTA. The latter part discussed about GATS and remedies in public international laws pertaining to water ownership and water transfer laws.

To evaluate practice pattern and preference for use of serum peptide formulation by dermatologists for the treatment of alopecia. Dermatologists in India were administered a questionnaire consisting of questions related to number of patients with alopecia seen every week, investigations, prevalence of nutritional deficiencies and use of serum peptide formulation in telogen effluvium (TE) and androgenetic alopecia (AGA). The responses were analysed as number and percentages. Out of 124 dermatologists, 38 (31%) reported that they see 11-15 patients with TE every week and 31 (25%) reported seeing 11-15 patients of AGA per week. According to 51 (41%) dermatologists, 40-60% patients with hair loss have some nutritional deficiency and 95 (77%) reported that iron deficiency profile, thyroid stimulating hormone (TSH), vitamin B1 and vitamin D level estimation is necessary in patients with TE. A total of 86 (69%) dermatologists preferred serum peptide formulation in patients with TE and AGA. Ninety nine (80%) and 75 (60%) dermatologists reported “very good” or “good” efficacy of serum peptide in TE and AGA respectively. Ninety nine (80%) dermatologists said, gender is not an important criterion for choosing a serum peptide in hair fall. For aesthetics related parameters, Folliserum (Abbott Health care Pvt Ltd) was rated as “Very good” and “Good” by 66 (53%) and 38 (31%) dermatologists respectively. According to dermatologists in India, nutritional deficiency is common in patients with alopecia. Majority of the survey participants rated Folliserum as “Very good” or “Good” for its efficacy and aesthetic parameters.

Authors: Wang Hongqiao , Cheng Shuang
Published: December 2020

This paper attempts to disclose the law of land use variation in the Northeast China Tiger and Leopard National Park (NCTLNP), and provide theoretical basis for eco-environment protection of the national park in future. The data on land use variation in four phases (i.e., 1995, 2005, 2015, and 2018) were selected for analysis based on the geographical information system (GIS). The variation and transfer features of land use were quantified, with the aid of single land use dynamic degree, comprehensive land use dynamic degree, and land use transfer matrix. The results show that: (1) In 1995-2008, the main land types in the NCTLNP were forest, grassland, and cultivated land, which took up more than 90% of the total area; the grassland area increased, while the areas of cultivated land and forest declined; forest was the land use with the largest transfer-out area (523.59 km2), about 55.29% of the total transfer-out area in the study area; (2) In the sample period, NCTLNP witnessed significant transfers between land uses; the transfers mostly occurred between forest, grassland, and cultivated land; forest transfers were observed in every county and city; the transfer of forest to grassland mainly concentrated in Dongning City. The research results lay the basis for building up a stereo eco-environment monitoring network in the study area, and provide the research direction for eco-environment protection in the NCTLNP.

Published: December 2020

There is no precedent for the application of rotary flow jetting tool in the drainage gas recovery under gas wells. Based on the motion principles of jet flow and vortex flow, this paper designs a downhole rotary flow jetting tool, and verifies the feasibility of the tool through fluid simulation. Next, an indoor experiment device was established for drainage gas recovery with rotary flow jetting tool by the principle of similarity, and the structural parameters of the tool were subject to multi-objective optimization through orthogonal experiments. The optimized tool can achieve ideal rotary flow height and discharge volume. The results show that the proposed rotary flow jetting tool can effectively separate gas from liquid, and produce a rotary flow. The optimal structural parameters were determined as follows: the pitch diameter of spiral body is 45mm, the throat pipe length is 247mm, the spiral angle is 55°-60°, the spiral wing width is 4-6mm, and the nozzle diameter is 15-25mm. In addition, the number of side holes of the throat pipe has little effect on the jetting effect.
Special Aspects of Organizing Celebrations in St. Petersburg (Petrograd) and Moscow in 1894–1924: Space, Time, Ideology
Authors:   Archive of the Russian Academy of Sciences, Limanova Svetlana A.
Published: December 2020

The article is devoted to revealing the ways of organizing the metropolitan celebrations in 1894–1924. The author focuses on the city’s metropolitan area, which was the ‘stage’ for preparing public celebrations, first by the autocratic monarchy, then by the Provisional government, and finally by the Soviet government. Based on organizational documentation, the article shows the transformation of the influence on the choice of the triumph vector from centralization to decentralization and vice versa. Using sources of personal origin, the ambiguous process of ‘erasing’ the past is traced. And attempts to design new types of celebrations are considered. As a result, it is concluded that there is continuity in the organization of ceremonial events at the state level of the late Imperial and early Soviet periods, as well as in the use of commemorative practices.

The article critically assesses the absence of a definitive provision in the Russian criminal law that does not meet the criterion of legality, revealing the qualifying features of kidnapping. Examples of contradictory court decisions resulting from this are given. The relevant legal norms of some CIS countries are analyzed. It is concluded that the definition of kidnapping developed by judicial and investigative practice and reflected in the decisions of the Supreme Court of the Russian Federation is more specific. It is argued that it should be fixed in art. 126 of the Criminal Code of the Russian Federation.
Current trends in the development of geothermal resources
Authors: Shulyupin Alexander N. , Varlamova Natalia N.

Based on the analysis of publications in world publications, as well as a generalization of the experience of developing domestic geothermal fields, current trends in the development of geothermal resources are shown. The key trend is considered to be the transition from subsidized to commercial projects, which increases the relevance of research in areas that have a significant impact on the economic efficiency of resource development processes, primarily in the direction of geothermal technologies. In terms of subsidized projects that set research goals, the most relevant are works in the direction of EGS (Enhanced Geothermal Systems). Moreover, there is a tendency towards the creation of international interdisciplinary collaborative research teams. It is noted that the current level of technology development allows producing geothermal energy for use in local heat supply systems practically anywhere in the world. However, given the concentration of power per unit area, the basis of modern geothermal energy is still the direction associated with the rise of deep fluids to the surface in areas characterized by the presence of ascending flows of hot juvenile fluids. It is indicated that Russia is lagging behind the world level of progress in the development of geothermal resources, including in terms of current research and development directions, and measures are proposed to overcome this lag.
Simulating Heat Exchange and Friction in a Thin Laminar Boundary Layer of Air over the Lateral Surface of a Blunted Cone Featuring a Low Aspect Ratio

It is not possible to obtain a high-quality solution to a convective heat transfer problem without numerically integrating the differential equations describing the boundary layer, which involves a whole range of computational issues. Developing relatively simple yet adequately accurate computation methods becomes crucial. Using the effective length method may be considered to be the first step towards solving this problem. This method boasts an accuracy of convective heat transfer calculation that is acceptable in practice, due to which it became prevalent in aircraft design. However, this method is also relatively labour-intensive, although significantly less so than numerical integration of the boundary layer differential equations. The most efficient approach to solving heat transfer and friction problems in engineering practice would be using simple algebraic equations based on fitting the results of rigorous numerical computations or experimental investigations. Regrettably, there is no information published regarding how accurate these equations are for various operation conditions. The paper presents a solution to this problem based on deriving systematic numerical solutions to the boundary layer equations in the most rigorous analytical statement, along with conducting a thorough analysis of the equation accuracy for both the equations derived and previously published

The aim of the study was a veterinary and sanitary assessment of meat and slaughter products in cattle fasciosis. To achieve the goal, depending on the intensity and extensiveness of fasciolous invasion, meat carcasses received by the laboratory of veterinary and sanitary examination of the market were divided into four groups: with a low degree of invasion; with a moderate degree of invasion; with a high degree of invasion and no signs of invasion. Safety assessment of slaughter products was carried out using organoleptic, physicochemical indices, bacterioscopic examination of smears and microbiological analysis of meat. As a result of the studies, it was found that the infection of cattle with fasciosis leads to changes in the organoleptic and physicochemical characteristics of meat. The strongest deviations in physicochemical indicators were recorded in the group with a strong degree of invasion: the reaction with copper sulfate and the formal reaction turned out to be slightly positive. In sanitary microbiological examination, no bacteria of the E. coli group, bacteria of the genus Proteus, bacteria of the genera Salmonella and Listeria monocytogenes were found in all the studied samples, indicating the safety of meat. However, the total bacterial obscurity in samples from carcasses of the group with a strong degree of invasion exceeded the normative indicators (3,0 103±0,18 KOE/g).Therefore, cattle meat with a high degree of contamination should be sent for industrial processing within five days after slaughter.
Model detection and prediction of horizontal deformation of the earth’s surface based on the movement of its markes

Published: December 2020

Relevance of the topic. To identify areas of increased deformation of the earth’s surface of rock blocks containing a mineral Deposit, GPS monitoring measurements of horizontal movements of markes installed at different points are carried out. An actual problem that arises here is the creation of a methodology that reliably describes and predicts the formation and location of deformation zones based on the movements of labels. The aim of the research is to create a methodology for forming, calculating and applying a binary mathematical model that describes and predicts the location and contours of the resulting areal deformations of the earth’s surface of two neighboring rock blocks based on placemark movements. Research methods include mathematical modeling of areal deformation, functional and numerical optimization of the parameters of the created model, experimental calculations and analysis of the distribution of the resulting and predicted deformation in a practical example of placemark movements. Research result. The model is based on the idea of blocks based on the spatial constraints of their horizontal dimensions and elastic properties in the hierarchical mosaic structure of composing rocks. Assuming that the size of a block of the earth’s surface does not exceed 5 km within the limits of a mineral Deposit, the movements of its points are considered in the plane. The resulting areal deformation is represented by the sum of linear and angular deformations. The model parameters were identified using the methods of least squares and parabolic vertex approximations implemented in the specified sequence of iterative calculations using the given optimization formulas. Calculations are regulated by the standard deviation of model and labels displacements. It boils down to the permissible small limit determined by the GPS positioning error. A practical example of interpreting placemark offsets shows the properties of model invariance in a multidirectional spatial coordinate system, as well as the detection of areal deformation zones and the forecast of its contour development. Conclusions. The applicability of the presented methodology for the deformation interpretation of multidirectional movements of the earth’s surface markes registered by the monitoring system is noted. The model’s conclusions about the areal location of deformation zones and its level can be used in predictive estimates and criteria that determine the possibility of safe mining operations in the detected zone and the content of man-made objects in it.
