Published: May 2022

The Internet of Things (IoT) has gained immense popularity over the last decade with wide-ranging applications in domains of medicine, science, military as well as domestic use. Despite its tremendous growth, privacy concerns plague IoT applications and have the potential to hamper the benefits derived from its usage. This paper carries out a statistical analysis of empirical data collected from users of IoT to assess the level of awareness among users of IoT. The mode of study was through a questionnaire sent through Google forms to a selection of Indians living across the U.S. The place was chosen as some of the authors were in that country and also because its usage is more in the U.S. Many homes have extensive use of IoT, even if it’s for simple operations like turning on/off electric bulbs. Privacy issues have also been a matter of concern as these devices are linked to the internet. The sample was chosen from judgment /convenience sampling. Only one member per family was asked to respond so that there is no overlap of the collected data. The respondents were asked about the privacy issues of using IOT devices and also if it bothered them to continue usage. The results showed that not only were users aware of the privacy issues related to IoT, but they also expressed concerns over the same. Due to the convenience and ease of usage, it is highly unlikely that people will stop using these devices but definitely, the usage will be more guarded in the future.

Published: May 2022

This paper is for detecting power sync errors. The actual power grid consists of power sources that are synchronously connected to power the system. These power supplies must be powered according to grid rules. These rules include voltage and frequency fluctuations within certain limits. Deviations from these limits require that this data source be immediately disconnected from the network and affected. This is known as solo operation. It is used to avoid large voltage drops or power outages from the grid. Our system is designed to warn the network of a power failure, so the network can use other backup data sources as needed to avoid a complete power failure. Our system demonstrates this with the ATmega328P microcontroller. MC is used to detect voltage and frequency from a set of comparators. Since the frequency cannot be changed, use the frequency generator (555 timer). Standard variacs are also used to vary the input voltage of the system. Normal loads are used to indicate the expected power outage or power outage if the voltage / frequency deviation exceeds the limit.

Authors:   Belarusian State Medical University, D.A. Kluiko , V.E. Korik ,   Belarusian State Medical University
Published: May 2022

Adhesive disease of the abdominal cavity is currently an important medical and social problem, characterized by frequent relapses, decreased ability to work and the quality of life. The aim of the study was to analyze the patterns of development of adhesive disease of the abdominal organs on the basis of autopsy protocols. As a result of the study, it was proved that the likelihood of an unfavorable outcome is significantly influenced by the age and time of seeking medical care from the moment of the onset of the disease. While the older the patient, the later he seeks medical help and the longer he is in hospital; surgical treatment of adhesive intestinal obstruction in comparison with planned adhesiolysis is associated with an increase in the likelihood of complications, in particular: early adhesive obstruction by 88.9%, perforation of the hollow organ by 73.9%, peritonitis by 72.7%, which proves the presence of a syndrome of mutual burden, progression of multiple organ failure and the need for an integrated approach to patient treatment. In the pathological diagnosis of the abdominal adhesions, 29% of the deceased were noted, while 71% of the surgical procedures mentioned it, which indicates the prevalence of this disease.
DYNAMICS OF THE QUALITY OF LIFE OF PATIENTS UNDER ABDOMINAL SURGERY
Authors:   Belarusian State Medical University, D.A. Kluiko
Published: May 2022

The quality of life of patients undergoing surgery is a subjective measure of psychological and physical well-being. In order to assess the quality of life indicators, the results of a survey conducted using the Russified questionnaires SF-36 v.2 and AQLi were analyzed. The aim of the study was to determine the dynamics of the quality of life of patients before and after undergoing surgery. The application of the new AQLi scale will make it possible to objectify the indications for surgical intervention, namely, when the Summ value is less than 65 and the SBP is reliably confirmed by instrumental research methods, the performance of planned adhesiolysis is shown. The main indicators in the group of patients with acute adhesive intestinal obstruction, operated on by the laparoscopic approach, had higher values and came to normal earlier than those in the group with the laparotomic access, which indicates a better tolerance of laparoscopic surgical interventions in this pathology.

Part 1. Approaches to the study of the spatial-temporal model of alcohol dependence In the present part of the work the authors considered the approaches to the study of alcohol dependence problem in the spatial-temporal aspect. There were revealed the factors, which contribute to its formation: functional and structural inferiority of the temporary spiral, ritualization of alcohol intake, its specific socialization and also desocialization, various types of motivations, where ataractic is of priority, as well as mechanisms of development: copying, multiplication and dissociation of temporary spiral. It is shown that formation of alkagol dependence is due to the disruption of this spiral for the creation of the internal energy of the human organism, with a deficiency of which he is largely forced to resort to excessive alcohol consumption as its source. This model makes it possible to unwind mental and somatic disorders that are formed during alcohol dependence, in line with the energy concept. Key words: alcohol addiction, formation factors and mechanisms, temporary spiral.

Authors:   Belarusian State Medical University, S.E. Fedorovich
Published: May 2022

At present interaction peculiarities of disease-modifying anti-rheumatic drugs and respiratory system in patients with spondyloarthritеs and rheumatoid arthritis are subject to thorough investigation and reassessment. Objective. To assess the impact of disease-modifying anti-rheumatic drugs (methotrexate) on the respiratory system in patients with spondyloarthritеs and rheumatoid arthritis. Material and methods. The research involved 172 patients with spondyloarthritеs and rheumatoid arthritis. The patients were interviewed and examined. The multispiral computer tomography of thorax was performed in order to determine the volume and nature of lung affection. Lung function was tested by means of spirometry and body plethysmography. In order to process the data Statistica 10 software package was used. Results. Lung disorders were found in 77,1% of patients with rheumatoid arthritis who were taking methotrexate while the percentage of patients with lung affection who were not taking disease-modifying anti-rheumatic drugs reached 100%. The patients with spondyloarthritеs or rheumatoid arthritis who were taking methotrexate showed significantly higher parameters of vital capacity and forced vital capacity than the patients with spondyloarthritеs or rheumatoid arthritis who were not taking disease-modifying anti-rheumatic drugs. Conclusion. Lung disorders were found more rarely in patients with rheumatoid arthritis who were taking methotrexate as compared to patients with rheumatoid arthritis who were not taking disease-modifying anti-rheumatic drugs. Taking into account the assessment of the lung function, we can talk of absence of the negative impact of methotrexate on the respiratory system in patients with spondyloarthritеs and rheumatoid arthritis.
Firing and post-firing dynamics of Mg- and Ca-rich bricks used in the built heritage of the city of Padua (northeastern Italy)
Authors: Pérez-Monserrat Elena Mercedes , Maritan Lara , Cultrone Giuseppe
Published: May 2022

Abstract. Diverse types of bricks from monuments in the city of
Padua (northeastern Italy) were studied using a multi-analytical approach
based on spectrophotometry, X-ray fluorescence (XRF), X-ray powder
diffraction (XRPD), polarized-light optical microscopy (POM) and/or
high-resolution scanning electron microscopy with coupled energy-dispersive X-ray spectroscopy (HRSEM-EDS). The most
representative bricks were yellow or beige and in well-preserved condition.
The results showed that they were made of Mg- and Ca-rich illitic clays,
were fired at high temperatures (from 900 to over 950 ∘C), and
achieved an incipient vitrification. Two main processes took place during
firing: (i) the development of a Ca-aluminosilicate amorphous phase where
very abundant pyroxene-type crystals were nucleated and (ii) the
transformation of the pristine Mg-rich clayey grains into Mg-silicate
mineral phases. The analyses suggest a firing dynamic within a highly
reactive and supersaturated unstable system, particularly rich in calcium
and magnesium. There are also signs of the rapid heating and/or soaking of
the bricks and the irregular heat distribution and/or different residence
times inside the kilns. The formation of zeolite and calcite secondary
phases was also observed. The former was largely promoted by the high
calcium content of the bodies and the very humid conditions, while the
latter was mainly precipitated from Ca-rich solutions. The preservation of
the bricks was enhanced by processes that took place both during and after
firing. Firstly, the significant development of a Ca-rich amorphous phase
and of high-temperature pyroxene-type crystals has provided strength to
the bricks. Secondly, the porosity yielded by the firing of the
carbonate-rich clays was almost filled by secondary calcite, which acted as
a cementing agent. The information attained has increased the knowledge of
(i) the mineralogical and microstructural changes that take place during the
firing over 900 ∘C of Ca- and Mg-rich illitic clays and (ii) the
formation of secondary phases within highly calcareous bricks laid in very
humid environments and affected by Ca-rich solutions. The key role of the
Ca- and Mg-rich raw clays and of the high firing temperatures, in producing
high-quality bricks, and of the secondary calcite, which increased their
durability, is highlighted. All these factors have contributed to the better
preservation of the built heritage of the city.
OPTIMAL POSITION AND PATH PLANNING FOR STOP-AND-GO LASERSCANNING FOR THE ACQUISITION OF 3D BUILDING MODELS

Published: May 2022

Abstract. Terrestrial laser scanning has become more and more popular in recent years. The according planning of the standpoint network is a crucial issue influencing the overhead and the resulting point cloud. Fully static approaches are both cost and time extensive, whereas fully kinematic approaches cannot produce the same data quality. Stop-and-go scanning, which combines the strengths of both strategies, represents a good alternative solution. In the scanning process, the standpoint planning is by now mostly a manual process based on expert knowledge and relying on the surveyor’s experience. This paper provides a method based on Mixed Integer Linear Programming (MILP) ensuring an optimal placement of scanner standpoints considering all scanner-related constraints (e.g. incidence angle), a full coverage of the scenery, a sufficient overlap for the subsequent registration and an optimal route planning solving a Traveling Salesperson Problem (TSP). This enables the fully automatic application of autonomous systems for providing a complete model while performing a stop-and-go laser scanning, e.g. with the Spot robot from Boston Dynamics. Our pre-computed solution, i.e. standpoints and trajectory, has been evaluated surveying a real-world environment using a 360° panoramic laser scanner and successfully compared with a precise LoD2 building model of the underlying scene. The performed ICP-based registration issued from our fully automatic pipeline turns out to be a very good and safe alternative of the otherwise laborious target-based registration.
ASSESSING QUALITY OF CORSNET-NSW INFRASTRUCTURE FOR USE IN REGIONAL NEW SOUTH WALES, AUSTRALIA
Authors: McMahon S. , Paudyal D. R.
Published: May 2022

Abstract. CORSnet-NSW is a network of Global Navigation Satellite System (GNSS) Continuously Operating Reference Stations (CORS) covering the state of NSW and providing centimetre-level real-time positioning. This research paper aims to determine the level of accuracy and precision of CORSnet-NSW in regional parts of the network and compare them to that of traditional RTK under identical conditions. It investigates what effects satellite geometry and proximity to a CORS station have on NRTK measurements. It also verifies the CORSnet-NSW claim of network wide 2cm accuracy. The claim was found to be true at the 68% Confidence Interval. Changes in satellite geometry were not found to affect the results for the most part. It was also found that CORSnet-NSW precision was affected by the proximity of the rover to the base/calibration points more than its proximity to a CORSnet-NSW station. However, even though the CORSnet-NSW results were better than expected, traditional RTK remains the most precise and consistent method. This research paper provides GNSS users in regional NSW with the evidence they need to make informed decisions regarding which type of RTK method is fit for their purposes.
POSE ESTIMATION THROUGH MASK-R CNN AND VSLAM IN LARGE-SCALE OUTDOORS AUGMENTED REALITY

Published: May 2022

Abstract. Deep Learning (DL) ingrained into Mobile Augmented Reality (MAR) enables a new information-delivery paradigm. In the context of 6 DoF pose estimation, powerful DL networks could provide a direct solution for AR systems. However, their concurrent operation requires a significant number of computations per frame and yields to both misclassifications and localization errors. In this paper, a hybrid and lightweight solution on 3D tracking of arbitrary geometry for outdoor MAR scenarios is presented. The camera pose information obtained by ARCore SDK and vSLAM algorithm is combined with the semantic and geometric output of a CNN-object detector to validate and improve tracking performance in large-scale and uncontrolled outdoor environments. The methodology involves three main steps: i) training of the Mask-R CNN model to extract the class, bounding box and mask predictions, ii) real-time detection, segmentation and localization of the region of interest (ROI) in camera frames, and iii) computation of 2D-3D correspondences to enhance pose estimation of a 3D overlay. The dataset holds 30 images of the rock of St. Modestos – Modi in Meteora, Greece in which the ROI is an area with characteristic geological features. The comparative evaluation between the prototype system and the original one, as well as with R-CNN and FAST-R CNN detectors demonstrates higher precision accuracy and stable visualization at half a kilometre distance, while tracking time has decreased at 42% during far-field AR session.
VIRTUAL DATA SPHERE: INVERSE STEREOGRAPHIC PROJECTION FOR IMMERSIVE MULTI-PERSPECTIVE GEOVISUALIZATION

Published: May 2022

Abstract. Immersive geospatial visualization finds increasing application for navigation, exploration, and analysis. Many such require the display of data at different scales, often in views with three-dimensional geometry. Multi-view solutions, such as focus+context, overview+detail, and distorted projections can show different scales at the same time, and help place an area of interest within its surroundings. By inverting the principle of stereographic projection – projecting spatial features from a map onto a virtual sphere which surrounds the viewer – we present a novel technique for immersive geospatial focus+context that aims to mitigate problems with existing solutions. This sphere can intersect the map, dividing it into two parts: the inside of the sphere, which stays unchanged, and the outside, which gets projected to the surface, resulting in an inversion of the lens metaphor by distorting the context instead of the focus. This detail-in-context visualization maximizes the amount of context that can be legibly shown by the smooth compression inherent to the stereographic projection, and by utilizing otherwise unused screen space in the sky. The projection method allows for easy control over the projection and distortion characteristics by varying only two main parameters – the sphere’s radius and its position. The omnidirectional nature of our system makes it particularly well-suited for immersive displays by accommodating typical immersive exploration and fully utilizing the additional visual space available. Applying our system to an urban environment, we were able to solicit positive reactions during feedback sessions with experts from urbanism.
INTEGRATING GEOSPATIAL DATASETS FOR URBAN STRUCTURE ASSESSMENT IN HUMANITARIAN ACTION
Authors: Riedler B. , Lang S.
Published: May 2022

Abstract. More than half of the world-population lives in urban areas, with more than 1 billion people lacking basic services and infrastructure. Spatially targeted, data-driven policies are crucial for sustainable urban planning to improve these situations and increase the resilience. Earth observation (EO) can support the process of achieving the SDGs, in particular SDG 11. Aiming at such high-level targets requires a multi-source data environment, defining and extracting suitable EO-based indicators and linking them with socio-economic or environmental data. When embedded in the context of humanitarian response, where physical access to regions is often limited while at the same time, insights on several scales of intervention are key to rapid decisions, the integration of (potentially) heterogeneous datasets requires adequate data assimilation strategies and a good understanding of data quality. This paper investigates the usability of datasets regarding technical and organisational aspects from an application-driven point of view. We suggest a protocol considering various quality dimensions to evaluate via scoring the fitness of multi-source geospatial datasets to integration. The aim is to provide a general orientation towards data assimilability in the context of deriving higher-level indicators, while specific constraints and the need to relativize may occur for concrete use case.
BOOSTING U-NET WITH FOCAL LOSS FOR ROAD MARKING CLASSIFICATION ON SPARSE MOBILE LIDAR POINT CLOUD DERIVED IMAGES
Authors: Lagahit M. L. R. , Matsuoka M.
Published: May 2022

Abstract. Road markings play an important role in vehicular navigation. It helps provide sufficient information for safe driving and smooth traffic flow. As such, with the rise of digital maps such as High-Definition (HD) maps, which are used by autonomous vehicles or self-driving cars, they must be well represented in their digital counterparts. However, survey-grade mobile mapping systems are expensive and thus open the idea of using lower-cost/level LIDAR sensors for mapping. Unfortunately, using such sensors provide sparser point clouds. This work aims to propose a method that successfully classifies road markings on sparse mobile LIDAR point cloud-derived images using UNET trained with focal loss. Results have shown successful road marking classification with a 94.68%increase in recall and a maximum 49.39% increase in F1-score. Adjusting precision by removing the insignificant class (“black”) further increases the resulting F1-score to 82.74%. Extending the method produces a classified point cloud by combining the classified image with a depth image. This research also aims to help aid boost the research on lower-cost/level sensors for mobile mapping purposes.
Counter-rotating eddy pair in the Luzon Strait

Published: May 2022

Abstract. Based on satellite remote-sensing observation data and Hybrid Coordinate
Ocean Model (HYCOM) re-analysis data, we studied the counter-rotating eddy
pair in the Luzon Strait (LS). Statistical analysis reveals that when an
anti-cyclonic mesoscale eddy (AE) (cyclonic mesoscale eddy [CE]) in the
Northwest Pacific (NWP) gradually approaches the east side of the LS, a CE
(an AE) gradually forms on the west side of the LS, and it is defined as the
AE (CE) mode of the counter-rotating eddy pair in the LS. The
counter-rotating eddy pair exhibits obvious seasonal variation: the AE mode
mainly occurs in the summer half of the year, while the CE mode mainly
occurs in the winter half of the year. The mean durations of the AE and CE
modes are both approximately 70 d. Based on the vorticity budget equation
and energy analysis, the dynamic mechanism of counter-rotating eddy-pair
occurrence is determined to be as follows: the AE (CE) on the east side of
the LS causes a positive (negative) vorticity anomaly through horizontal
velocity shear on the west side of the LS, and the positive (negative)
vorticity anomaly is transported westward by the zonal advection of the
vorticity, finally leading to the formation of the CE (AE) on the west side
of the LS.
