Identifying the influence of design parameters of single-chamber hydrostatic bearing of fuel pump on its main characteristics
Authors: Nazin Vladimir
Published: March 2024

The object of this study is hydrostatic processes in the fluid friction bearings of gear-type aviation fuel pumps.
The problem of the influence of the design parameters of a single-chamber hydrostatic bearing on its main characteristics was solved. The main characteristics were considered to be the load-bearing capacity and the flow rate of the working fluid. When determining the main characteristics of a single-chamber hydrostatic bearing, the Reynolds and flow balance equations were solved jointly. The resulting diagram of pressure distribution over the working surface of the bearing was used to determine the main characteristics.
The influence of the clearance, nozzle diameter, and chamber width on the load-bearing capacity and working fluid flow of a single-chamber hydrostatic bearing was studied.
It has been established that as the gap increases, the load-bearing capacity of a single-chamber bearing decreases, and the flow rate of the working fluid increases. As the nozzle diameter increases, the bearing's load-bearing capacity increases. Increasing the width of the chambers leads to an increase in the load-bearing capacity and flow of working fluid through the bearing. When the gap increases from 0.0125 mm to 0.0425 mm, the bearing capacity decreases by 1.156 times. The flow rate of working fluid through the bearing increases by 1.4 times. With an increase in the nozzle diameter from 1.5 mm to 3 mm, the bearing capacity increases slightly by approximately 1.02 times. Increasing the width of the chambers from 4 mm to 8 mm increases the load-bearing capacity by 1.29 times and increases the flow rate of working fluid by 1.4 times.
The results show that a single-chamber hydrostatic bearing can provide the required load-bearing capacity by selecting design parameters. The given mathematical dependences could be used for practical calculations of single-chamber hydrostatic bearings

The object of research is a riverbed in the area of a bridge crossing, which is subject to the action of high water during the passage of a flood.
The selection of parameters and contours of the scheme of the river section was carried out using a mathematical model of the flow and deformation of the bed of the riverbed before and after the change of its shape. It was established that the assignment of parameters of the operational slot should be performed on the basis of the principle of creating natural analogs of riverbed shapes, riverbed and floodplain terraces, with the use of mathematical modeling.
To reduce erosion in the area of bridge crossings, it is proposed to regulate the riverbed by constructing a canalized riverbed. Modeling according to this option showed that the erosion in the span of a road bridge decreased and did not exceed 1.5 m. In addition, it was established that a significant role in ensuring the stability of the river is played by the vegetation cover in floodplain areas.
Using the method of mathematical modeling, it was established that the area near the convex bank with a width of 150 m is subject to the strongest erosion in the design of the supports. Siltation of the existing left-bank bottom basin is also observed.
It is recommended to make a decision to carry out restorative cutting of riverbed alignment annually after receiving a flood forecast from the local hydrometeorological station. In the case of a high flood warning, work should be carried out to clear the sleeves on the approach to the construction of the bridge deck.
It was established that the most stable shape of riverbeds is in the form of curvilinear incomplete meandering when the radii of curvature R and the width of the riverbed B satisfy the ratio R=(4...7) B at riverbed-forming flow rate. At the same time, radii of curvature R<3.5 B should not be allowed, as this leads to separation of the flow from the convex bank and excessive erosion of the concave bank

Published: March 2024

This study examines the effectiveness of neural network architectures (multilayer perceptron MLP, convolutional neural network CNN, recurrent neural network RNN) for human voice recognition, with an emphasis on the Kazakh language. Problems related to language, the difference between speakers, and the influence of network architecture on recognition accuracy are considered. The methodology includes extensive training and testing, studying the accuracy of recognition in different languages, and different sets of data on speakers. Using a comparative analysis, this study evaluates the performance of three architectures trained exclusively in the Kazakh language. The testing included statements in Kazakhs and other languages, while the number of speakers varied to assess its impact on recognition accuracy.
During the study, the results showed that CNN neural networks are more effective in recognizing human voice than RNN and MLP. Also, it was found that the CNN has a higher accuracy in recognizing the human voice in the Kazakh language, both for a small and for a large number of announcers. For example, for 20 speakers, the recognition error in Russian was 21.86 %, whereas in Kazakhs it was 10.6 %. A similar trend was observed for 80 speakers: 16.2 % Russians and 8.3 % Kazakhs. It can also be argued that learning one language does not guarantee high recognition accuracy in other languages. Therefore, the accuracy of human voice recognition by neural networks depends significantly on the language in which training is conducted.
In addition, this study highlights the importance of different sets of speaker data to achieve optimal results. This knowledge is crucial for advancing the development of reliable human voice recognition systems that can accurately identify different human voices in different language contexts

Published: March 2024

The object of this study is the production technology of Tokaj-type wine materials. The material used was white and red grape varieties, withered by twisting on the vine for 4–5 days. Wine materials were prepared from these grape varieties using new technology, i.e., by adding the wort to the alcohol along with the pulp. The technology for the production of environmentally friendly Tokaj-type sweet dessert wines using technical grape varieties cultivated in the foothills of the Goy-Gol and flat zone of the Samukh region has been improved. Providing the population with environmentally friendly food products, as well as wines, is one of the most important tasks of our time. Poor quality food creates conditions for the development of various diseases. For this purpose, a technological scheme for the production of Tokaj-type wine materials has been devised. The quality indicators of Tokaj wine material prepared by fermenting in alcohol must from grapes withered by twisting on the vine for 4–5 days with pulp for 3–4 days were studied. The rates of alcohol loss were calculated based on the contraction coefficient (0.08 %) during co-fermentation with wort. For wine materials prepared from grape varieties grown under the conditions of the Samukh region, alcohol consumption is reduced. This is due to the high sugar content in the wine material. In the prepared wine material, the amount of alcohol and sugar corresponded to the norm – the alcohol content reached 14–15 % and residual sugar 16 %. As a result of the tasting, wine material prepared from the Rkatsiteli grape variety in the Samukh region was rated 9.5 points, and wine material prepared from the red Madras grape variety 9.3 points. The results make it possible to regulate the desired quality of wine material and use it in the production of Tokaj wine

Published: March 2024

The object of research is the process of searching and analyzing images of raster graphics. In the context of this work, the problem of the lack of an effective and fast procedure for determining the similarity of images was solved.
The technology for improving the construction of a software tool for determining the similarity of raster graphics images by devising a procedure for determining the similarity of images using a hash code that corresponds to all variants of the image, regardless of size and aspect ratio, is reported. The image features of raster graphics were systematized.
A procedure for determining the similarity of images using a hash code is proposed. This procedure makes it possible to process all possible variants of the image, regardless of the size and aspect ratio. The resulting indicator of the proposed procedure is the value of the hash codes.
It is proposed to use the mathematical apparatus of fuzzy logic by introducing linguistic variables to estimate the similarity index. A comparison of the numerical values of similarity, obtained on the basis of the use of information systems, and the linguistic values revealed in the survey process was carried out. Threshold values were obtained that make it possible to assess the degree of similarity of the images.
Based on the proposed algorithm, a prototype of the information system for determining the similarity of images of raster graphics has been designed. As a result of the calculation of the numerical characteristics of the improvement of the technology of constructing a software tool for determining the similarity of images of raster graphics, the value of the precision indicators was approximately 0.89 and the completeness was 0.8. The advantage of the proposed technology for determining the similarity of images over known analog technologies is illustrated by the amount of RAM of the developed software, which is 210 MB

Published: March 2024

Modern heterogeneous packet networks generate network traffic with a complex structure. In this article, the object of study is a time series. The total number of User Datagram Protocol (UDP) packets has reached 250242. According to analysts, the growth trend of traffic, including real-time applications, will continue and the volume of data will grow, which may lead to the formation of packet queues when processed by network devices. In this case, there may be losses in case of long queues. To solve this problem, a power spectrum assessment was carried out. The AR maximum entropy estimator has been shown to be more sensitive than the auxiliary Fourier estimator.
Accounting for non-stationarity by spectral methods is possible only through estimation in a sliding time window. Nine diagrams of spectral-temporal analysis of the original series, its increments, and the mixed series of increments were obtained: with default parameters, with small and large windows. Diagrams related to the original series reflect the dynamics of changes in data transmission intensity in the network; they show higher temporal resolution, indicating the presence of high-frequency components (noise) and the presence of low-frequency components (trend). Diagrams with increments describe signals of periodic components; changing the length of the window did not reflect the presence of noise or trend signs. Diagrams with mixed increments show that frequency components are uniformly distributed. The uniqueness of this work lies in the real measured data, and a distinctive feature of the obtained results is the visual examination of the complex traffic structure, allowing for the resolution of the investigated problem. Practical application of the results obtained can be applied in Quality of Service (QoS) management, resource planning, and network performance optimization

Published: March 2024

This study focuses on analyzing the influence of carbon black (CB) on Polybutylene terephthalate (PBT)/Polyamide 6 (PA6) blends. This study aims to solve the source of waste from toothbrush filament during production. This PBT/PA6 mixture does not meet the mechanical properties due to the incompatibility of these two plastics, which means this waste must be discarded and cannot be reused. When combined with CB, it creates a new type of plastic with more stable mechanical properties that can be applied in many areas of life and, at the same time, helps manufacturing businesses save on waste treatment costs. To create these PBT/PA6/CB blends, the research team used injection molding with a PBT/PA6 ratio of 75/25 combined with 0, 4, 8, and 12 % carbon black. The tensile and impact strength were tested according to the ASTM D638 and ASTM D256 standards. The results found that when adding 4 % CB to the PBT/PA6 plastic mixture, the tensile strength decreased from 34.9 to 34.8 MPa. Meanwhile, the tensile strength is improved when adding 8 % CB (35.3 MPa). At 12 % CB, a difference in tensile strength results, decreasing to 29.7 MPa. This result shows that the ratio 75/25 can give the best tensile strength value of the PBT/PA6 mixture with 8 wt. % CB. The impact strength was 3.5, 2.9, and 2.7 kJ/m2 according to 4, 8, and 12 % CB samples. Mechanical quality tests have shown that the tensile strength is improved when combining CB into the PBT/PA6 mixture, but the impact strength is reduced. SEM results show that most CB interacts with PBT/PA6 mainly because the PA6 particles are spherical and tend to separate easily from the mixture. The research found that increasing CB density worsens the bonding ability between PBT and PA6. These results help us provide experience for the most appropriate application for each purpose

Authors: Monroy Martín Emilo , Chanchí Gabriel Elías , Ospina Manuel Alejandro
Published: March 2024

The research focuses on addressing the global issue of cardiovascular diseases. The key variable under consideration for predicting cardiovascular diseases is heart rate variability (HRV). Leveraging the widespread adoption of IoT in various applications, particularly in the health sector, the study proposes the design and implementation of an IoT system for HRV monitoring. The research unfolded in four methodological phases: exploration and selection of technologies, definition of the IoT architecture, development of the prototype, and verification of its functionality. The implemented IoT system adheres to the conventional 4-layer IoT architecture: capture, storage, analysis, and visualization. Heart rate data is periodically acquired using a heart rate sensor and an Arduino-compatible board. The storage layer employs a non-relational database to store the captured data. The analysis layer extracts metrics related to HRV (High: RR <750 ms, Moderate: RR 750–900 ms, Low: RR >900 ms) by applying and delivering quantitative results from clustering algorithms such as machine learning models to evaluate data distribution. Risk levels indicate specific patient metrics. Thus, a 75-year-old patient exhibits an average HR of 75.56, Avg. RR of 795.42, falling into Cluster 1 with a risk value of 1.0. Similar detailed metrics and risk stratifications are presented for patients aged 68, 46, 37, and 18, demonstrating the system's robustness and efficacy in assessing cardiovascular risk. The visualization layer enables real-time observation of physiological variables, risk metrics, and results from data analytics models. The distinctive features of the results lie in the portability advantages of the IoT system, utilizing free hardware and software tools. This facilitates easy replication and utilization of the proposed system in medical campaigns, specifically for the early detection of cardiac conditions. The portable IoT system, leveraging free tools, enhances predictive capabilities for early cardiovascular risk detection globally
Bid Collusion in Public Procurement Law
Authors: Skrobotowicz Martyna
Published: March 2024

Unlawful agreements restricting competition, also known as bid rigging, is one of the acts of unfair competition specified by antitrust law. Its occurrence is associated with many unwelcome market practices, which is why it is considered to be a highly undesirable phenomenon and eliminated from economic turnover. In the field of public procurement, the phenomenon of bid rigging is particularly harmful because it leads to the inefficient management of public funds. For this reason, the legislator has included rules that prevent bid collusion in public procurement law institutions, assisting the contracting authority in protecting the competitiveness of the procedure. This paper focuses on a comparative analysis of the model of bid collusion, regulated under the Act on Competition and Consumer Protection with the provisions of Public Procurement Law. The act distinguishes bid collusion as a prerequisite for the subjective exclusion of contractors and the rejection of bids submitted under conditions of an act of unfair competition. However, under the provisions of Public Procurement Law, the definition of bid collusion derived from antitrust law has been modified, which has measurable consequences for the application of these provisions by contracting authorities and judicial authorities.

Authors: Zawadzka Joanna
Published: March 2024

This article presents the issue of surreptitious advertising against the background of the provisions of the Act on Combatting Unfair Competition. The paper presents an analysis of issues related to advertising, surreptitious advertising and the act of unfair competition. Surreptitious advertising is thus characterized as an act of unfair competition. The author also focused on the issue of surreptitious advertising n social media, which is a relatively new phenomenon that raises doubts in legal terms. The paper also describes the civil liability of entrepreneurs for committing an act of unfair competition in the field of surreptitious advertising. Problems with the creation of a uniform definition of advertising are indicated, which in turn cause difficulties in determining the definition and scope of surreptitious advertising. As a result of the analysis, the lack of a comprehensive legal act regulating the fight against unfair market practices and applicable to all trading participants was negatively assessed. This article is based mainly on the Act on Combatting Unfair Competition of 16th April 1993, as well as Polish and EU legal acts, court decisions, scientific literature, and also codes and recommendations created by governmental and non-governmental organizations.

A practical approach to determine the role of rockbolts in stoping gullies
Authors: Gouvea J.P. , Stacey T.R.
Published: March 2024

A research project was carried out on a gold mine in the Vaal River region of South Africa (Witwatersrand Basin) to evaluate the effect of two particular aspects of rockbolt installation - the angle of inclination of the bolt relative to the orientation of the rock surface, and the protruding length of the bolt - on the mine's gully support system. A keyblock analysis approach indicated that these factors do not have an adverse impact on the stability of the strike gullies. This was confirmed by extensive empirical data collected from the case study mine. While safety is the primary concern, cost saving opportunities can be realized through reconsidering historically inherited support standards that are perceived to be correct and appropriate. The research described in this paper sets forth a practical approach, that is easy to implement and repeatable, to evaluate the role of rockbolts in stoping gullies.
ФИЛОСОФСКО-АНТРОПОЛОГИЧЕСКИЕ СМЫСЛЫ РАЗВИТИЯ ЭКОЛОГИЧЕСКОГО ТУРИЗМА И ЛИЧНОСТИ ЧЕЛОВЕКА В ЦИФРОВУЮ ЭПОХУ
Authors: Саидова Липа Исаевна
Published: March 2024

Целью исследования является выявление и обоснование философско-антропологических смыслов и методологических ориентиров в изучении экологического туризма как агента становления и развития личности в цифровую эпоху.

Методологическую базу исследования составляет комплекс теоретических подходов и концепций, среди которых приоритетные позиции занимает антропологический подход в контексте сформировавшихся теоретических границ новой отрасли знания, во многом имеющей междисциплинарный характер, — антропологии туризма.

Результаты исследования позволили выявить непосредственную связь культуры и туризма как составляющих предметное поле антропологического подхода в философских исследованиях туризма. При этом в центре внимания оказываются задачи, связанные с анализом сущности, содержания, истории становления туризма, прежде всего культурного, проблемы становления и развития устойчивого (экологического) туризма как культурного явления.

Перспективу исследования составляет потенциал философско-антропологического анализа экологического туризма, в рамках которого глубокой рефлексии подвергается социокультурная природа эклогического туризма как продукта эволюции самого человека и общества в координатах совокупности отношений, складывающихся на различных уровнях человеческого бытия.
ТЕОРИЯ ЭКОНОМИЧЕСКОЙ ПОЛИТИКИ: ЦЕЛИ, ИНСТРУМЕНТЫ И ЭМПИРИЧЕСКИЕ ТРАКТОВКИ
Authors: Сухарев Олег Сергеевич
Published: March 2024

Статья посвящена вопросу возможной коррекции базового принципа в классической теории экономической политики «цели-инструменты», необходимость которой подтверждается проводимым эмпирическим анализом результатов антиинфляционной и политики роста в России.

Цель исследования — раздвинуть рамки классической теории экономической политики Тинбергена-Тейла за счёт рассмотрения структуры целей и инструментов, согласования этих структур, а также дать эмпирические трактовки проводимой макроэкономической политики в России в период 2003–2022 гг. по инфляции и росту экономики, чтобы подтвердить необходимость расширения указанной теории экономической политики.

Методология исследования базируется на продвинутой теории экономической политики за счёт авторской доктрины «распределённого управления», представляющей каждый инструмент макроэкономической политики имеющим изменяющуюся по объектам экономики силу влияния, так что чувствительность поставленных целей претерпевает изменение к набору инструментов, а сама совокупность применяемых мер приобретает собственное влияние на магистральные цели экономического развития.

Общий результат исследования сводится к тому, что эмпирическим анализом подтверждается «провал» классической теории экономической политики в достижении цели роста при снижении инфляции для российской экономики на рассматриваемом интервале времени. Это закономерно порождает необходимость выстраивания новой теории экономической политики, предполагающей учёт действующих факторов и применяемых мер макроэкономической политики совместно и с изменяемой силой влияния, распределённой по структуре экономики. Также показано, что более высокий уровень монетизации обеспечивал сдерживание инфляции и рост ВВП России, а больший темп роста денежной массы работал на инфляцию, что порождает необходимость поиска наиболее приемлемого с точки зрения согласования двух целей (по росту и инфляции) прироста денежной массы при сохранении общего вектора на монетизацию российского хозяйства. Такой итог одновременно составляет и перспективу для дальнейших исследований, поскольку вопрос о динамике наращения денежной массы в экономике давно и далеко вышел за пределы известного в теории «монетарного правила».

Published: March 2024

Актуальность данного проекта связана с необходимостью принятия государственных мер в отношении молодых людей с приобретенной инвалидностью в возрасте до 35 лет включительно.

Целью исследования является выявление факторов, определяющих: самосохранительный, ресурсный потенциал молодых мужчин с инвалидностью в рамках реализации Стратегии действий по сбережению мужчин и поддержке ответственного отцовства, разработанной в 2023 году авторским коллективом из числа ведущих ученых, членов Научного совета «Демографические и миграционные проблемы России» при Отделении общественных наук РАН. Указанные практики и типы поведения лежат в основе приумножения населения, сбережения мужчин, предотвращения их преждевременной смертности, формирования социальной нормы/модели ответственного отцовства и укрепления института многопоколенной традиционной семьи как принципиально важного ресурса для обеспечения национальной и демографической безопасности Российской Федерации. В то же время нельзя рассматривать самосохранительное, брачное, репродуктивное поведение мужчин и практики отцовства без учета экономической и социальной активности мужчин с инвалидностью.

Методологическую базу исследования представляют базисные положения концепции самосохранительного поведения, благополучия семьи, качества жизни населения, нормализации жизни инвалидов. В исследовании использовался такой научный метод, как сравнительный статистический анализ.

Результаты исследования. Демографическая безопасность, репродуктивное здоровье и семейное благополучие становятся важнейшей целью государства. При этом подразумевается внимание по отношению к социально уязвимым категориям граждан, молодым людям, испытывающим трудности социальной интеграции. Реализация проекта направлена на получение следующих результатов: проведение общественной экспертизы качества среды жизнедеятельности молодых людей с приобретенной инвалидностью, испытывающих трудности интеграции; развитие моделей и направлений адресной мобильной социальной работы с молодыми мужчинами с инвалидностью; развитие групп самопомощи и взаимоподдержки молодых людей, оказавшихся в трудной жизненной ситуации; распространение программ развития навыков и умений самостоятельной жизни для молодых людей с инвалидностью, испытывающих трудности в интеграции.

In this study, a regression model was constructed to predict the relationship between the value of the illiteracy rate and several independent variables using Multiscale Geographically Weighted Regression (MGWR) in South Sumatra province. These independent variables are the population (X1), the pure elementary school participation rate (X2), the pure junior high school participation rate (X3), the number of elementary school teaching staff (X4), the number of junior high school teaching staff (X5), and the percentage of poor people (X6).  MGWR was chosen because of the use of bandwidth in each variable, so it is expected to provide a model accuracy that is thought to be more accurate to the data. One of the ABH models found in Palembang City is Y= -0.0187+0.55X1-0.1748X2 - 0.0062X3 - 1.6129X4 + 0.5394X6.Keywords: Bandwidth, GWR, Illiteracy Rate, MGWR, Spatial Heterogenity. AbstrakMetode regresi dengan memperhatikan aspek spasial sering kali dipengaruhi oleh kondisi geografis dari masing-masing lokasi pengamatan. Pada penelitian ini dikontruksi model regresi untuk memprediksi hubungan nilai Angka Buta Huruf (ABH) dengan beberapa variabel bebas menggunakan Multiscale Geographically Weighted Regression (MGWR) di provinsi Sumatera Selatan. Variabel-variabel bebas yang dimaksud adalah jumlah penduduk (X1), angka partisipasi murni SD (X2), angka partisipasi murni SMP (X3), banyak tenaga pendidik SD (X4), banyak tenaga pendidik SMP (X5) , dan persentase penduduk miskin (X6).  MGWR dipilih karena memungkinkan penggunaan bandwidth pada setiap variabel, sehingga diharapkan mampu memberikan suatu ketepatan model yang diduga lebih akurat terhadap suatu data.

The activity of calculating the volume cut and fill in road works is generally depicted on a cross-section drawing in accordance with the road pavement plan. The distance between the cross-section of the road is determined by certain distance intervals marked with STA notation. The difference in the distance between STA intervals in each project implementing agency will affect the volume cut and fill obtained. Therefore, this study will analyze the cross-section distance interval in calculating the volume using the average end area method and its effect on straight and curved roads. The results of the volume calculation at each interval will be compared with the data that is considered correct. The volume calculation data that is considered correct is the result of manual calculation of the volume of the 25 meter STA interval profile data. The difference between the calculated volume and the volume that is considered correct will be analyzed using standard deviation and ASTM (American Society for Testing and Materials) tolerance test method with a tolerance limit of 2.78%.Keywords: ASTM, curved road, cut volume, fill volume, straight course

In building and road works, the calculation of excavation and embankment volumes is an engineering survey activity. Longitudinal and transverse profile drawings describe the relief of the ground surface in road works and are the basis for calculating the volume and position of excavations and embankments. Volume calculation is very important in highway construction because it can affect the amount of cost that will be obtained. The material volume calculation process uses various methods. The existing conditions of the tuban ring road are currently under construction and the volume calculation process still uses manual calculations. This research aims to calculate the volume of excavation by utilizing survey data processing applications on winding roads whose results will be compared with the volume of manual calculation results as data that is considered correct. The volume calculation analysis uses the ASTM tolerance test standard deviation with a tolerance limit of 2.78% as a condition of volume calculation accuracy. Based on the results of the standard deviation in the fill calculation, the average cross-section method is 2,665 m3 compared to the prismoidal method which is worth 4,001 m3 and composite volume with a value of 15,530 m3. In the fill calculation, the prismodial method has the smallest average standard deviation of 6.897 m3 compared to the average cross-section method of 12.611 m3 and the composite volume method of 19.777 m3. In the ASTM tolerance test with a tolerance value of 2.78% there is a volume calculation that does not meet the tolerance standards in the composite volume method with the largest difference in the calculation of cut and fill bend 3 with a difference of 3.998% cut and 16.277% fill and the smallest difference in the calculation of cut and fill bend 2 with a difference of 0.506% cut and 2.618% fill. The average cross-section method has better accuracy when applied to road bends, especially bends 1, 3, and 4 when compared to the results of the composite volume method. The prismoidal method has better accuracy when applied to road bends with bend-like characteristics.Keywords: Composite volume, Penampang Rata- Rata, Prismoidal, , Volume cut, Volume fill

A point positioning activity can be referred to as mapping. In mapping activities there is the term control framework point. One of the classification of control points is the horizontal control point. In mapping activities there is a minimum order of control points that can be used, that was horizontal control points order-4. The measurement of horizontal control points order-4 can be done by conventional survey methods using terrestrial method or using global positioning system technology. The development of global positioning system (GPS) technology has progressed very fast. One of the evidence of the development of GPS technology is where introduced of various instruments that exist today. Lowcost GPS is one type of GPS that has advantages in terms of more lower prices. The application of lowcost gps is expected to help in mapping activities. In this reserch, a feasibility analysis of lowcost GPS OEM Board K-708 and GPS Tersus BX-316as instruments in the measurement of horizontal control frame order-4 when compared with Geodetic GPS instruments. The analysis used in this study is standard deviation analysis and hypothesis testing using T-test. From the results of analysis conducted resulted in the accuracy of the instrument shown from the value of standard deviation that reached sub "cm", where the instrument GPS OEM Board K-708 has better standard deviation than GPS Tersus BX-316.

Algunas cuestiones sustantivas y procesales en el ámbito de la violencia de género en España

The great challenge of the legislator in the Organic Law 1/2004, of December 28, 2004, of integral protection against gender violence, has been, without a doubt, the creation of specialized judicial bodies, the courts of violence against women. The determination of the scope of their competence is one of the main topics of debate that the practical application of this Organic Law has led to. The most common procedures in the courts of violence against women are: speedy trial (urgent proceedings) and preliminary proceedings. The work of the forensic physician is very important and necessary, complementary to that carried out by other professionals. This interrelation results in the elaboration of a quality expert report adapted to the request made in the corresponding criminal procedure. The exception or dispensation to testify to the defendant's relative or spouse has the purpose of resolving the conflict that may arise for the witness between the duty to tell the truth and the bond of solidarity and familiarity that unites him/her with the defendant. Objective competence in civil order is determined by the simultaneous concurrence of three presuppositions: one of a material nature, a second of a personal nature and a third of a procedural nature.
Urban Borderlands: Difference, Inequality, and Spatio-Temporal In-Betweenness in Cities

The concept of urban borderlands helps us to understand how divisions take place in the city. Urban borderlands expand territorially beyond the mere linear border, drawing together what exists in or across both sides of the divide. In that they are not merely physical, but of course always socially, culturally, and experientially densely charged, the notion of the urban borderland offers itself as a useful analytic in the study of urban conditions that are marked by contiguity and coexistence. Contributions in this issue explore the potential of urban borderline studies across global cities, spanning various scales and employing theoretical frameworks such as borderlands, liminality, and multiple identities. This issue emphasizes the importance of considering bordering processes in urban planning and design and shows that urban borderlands are sites of contestation, negotiation, and coexistence, offering valuable lessons for the future of urban research and practice.

Monitoring of vertical displacements of the earth's surface on the right bank of the Kaniv Reservoir in the Vytatchiv-Stajky region was carried out using the differential radar interferometry (DinSAR) technique. According to the results of observations during the spring period from 2015 to 2023, active landslide areas are displayed. The DinSAR method is briefly described, emphasising data filtering steps for landslide activation mapping. A high data correlation was recorded, and the presence of zones of active shifts on the shore of the reservoir was confirmed. The spread and intensity of landslide manifestations are determined by the peculiarities of the geological and geomorphological structure of the territory, its tectonic, neotectonic and seismic regimes, and hydrological and climatic conditions. Limitations of the method arising from the temporal decorrelation of the radar signal in regions with a large amount of vegetation are determined. Due to the significant decorrelation between the obtained results of forested and watered areas, the DinSAR technique, a digital elevation model (DEM), analysis of base surface maps and the results of spectral index calculations were combined to identify regions of active landslides caused by waterlogging of the Dnieper slopes. The study demonstrates the feasibility of using DinSAR to detect and monitor surface deformation.
