When using groups of mobile robotic platforms (MRP), problems arise related to the management of individual platforms, the organization of cooperation in the group, and the management of the group as a whole. Management of the MRP group involves managing the actions of individual platforms to achieve the group's overall goal. To ensure the management of the MRP group in such a case, it is advisable to choose a hybrid method that requires solving the problem of conflict-free data exchange and control commands between the MRPs in the group. To solve this problem, it is proposed to improve the relevant methods and tools. The scientific novelty of the obtained research results is that a method of multi-channel conflict-free data exchange has been developed, which provides a real-time mode due to the coordination of the intensity of data arrival with the intensity of access. The method of controlling the movement of a group of mobile robotic platforms has been improved, which, by taking into account the changing parameters of the platforms and the changing state of the surrounding environment, provides effective management of the MRP group in real time. The practical significance of the research results is that it is proposed to use the CSMA/CA slotted mechanism for non-time-critical traffic to improve performance, and for time-critical traffic, coordinator-controlled access using guaranteed time slots. The hybrid method of management takes into account the advantages of centralized and distributed depending on specific tasks and conditions of use. It is proposed to use a multi-channel device for conflict-free exchange using the method of time allocation of RAM resources for data exchange in hybrid control. It is shown that global low-power networks LPWANs (Low-Power Wide Area Networks) can be used to transmit small blocks of data at a low speed when exchanging with MRP. It is proposed to use the slotted CSMA/CA mechanism for the transmission of non-time-critical traffic, and for time-critical traffic, coordinator-controlled access using guaranteed time slots. It is shown that the performance of the network during the conflict-free access period CFP depends on the results of the distribution of guaranteed GTS time slots among active users. LoRa technology was selected for long-distance data exchange between MRPs, which at the MAC (Media Access Control) sublayer allows for transmission planning and communication management between end devices and gateways, avoiding collisions and optimizing network performance.

A problem of navigation within large educational complexes has been identified, which poses a particular challenge for new students, visitors, and staff. It has been established that the implementation of augmented reality technologies considerably enhances the intuitiveness and usability of the navigation system. A comprehensive structural and mathematical model of the navigation system based on augmented reality technologies has been meticulously developed. This model formalizes the functional dependencies among the system components, enabling a deeper analysis of interconnections and optimization of operational processes. The working algorithm of the system, which utilizes cutting-edge augmented reality technology, is thoroughly described. A software solution for navigating between university buildings, using advanced augmented reality technology, has been developed. This system simplifies the spatial orientation within the campus during transitions between buildings, significantly enhancing the user experience. An interface that seamlessly combines intuitive understanding with visual attractiveness has been proposed, aiding users in effectively planning their academic day. Additionally, the system includes a module that provides visitors with essential information about respective university buildings and access to class schedules. The system architecture comprises several key blocks: the sensor block, the software and data processing block, the campus map integration block, the user interface block, and the interaction and personalization block. These components together ensure a seamless and personalized user experience. The design of the components has employed a systematic approach that ensures interface personalization, stringent data security, and efficient user interaction. In developing the application, the Kotlin programming language, MVVM architectural pattern, Dagger 2 libraries, and the ARCore platform for augmented reality, specifically tailored for the Android platform, were utilized. These technologies provide flexibility, scalability, and efficiency in development. Future research directions have been proposed, which include the further refinement of the software and the expansion of the system's functionality.

Published: September 2024

Linear and non-linear mathematical models for the determination of the temperature field, and subsequently for the analysis of temperature regimes in the braking systems of vehicles, which are geometrically depicted as isotropic spatial heat-active media that are subject to internal local thermal heating, have been developed. With the use of classical methods, it is not possible to obtain analytical solutions of linear and nonlinear boundary value problems of mathematical physics in a closed form. This is especially the case when the right-hand sides of differential equations with partial derivatives and boundary conditions are discontinuous functions. The given approach is based on the application of the apparatus of generalized functions to describe the local concentration of thermal influence. This made it possible to apply the integral transformation and, on this basis, to obtain analytical solutions of both linear and nonlinear boundary value problems. In the case of a nonlinear boundary value problem, the Kirchhoff transformation was applied, using which the original nonlinear heat conduction equation and nonlinear boundary conditions were linearized, and as a result, a linearized second-order differential equation with partial derivatives and boundary conditions with a discontinuous right-hand side were obtained. To solve the linear boundary value problem, as well as the obtained linearized boundary value problem with respect to the Kirchhoff transformation, the Henkel integral transformation method was used, as a result of which analytical solutions of these problems were obtained. For a heat-sensitive environment, as an example, a linear dependence of the coefficient of thermal conductivity of the structural material of the structure on temperature, which is often used in many practical problems, was chosen. As a result, an analytical relationship was obtained for determining the temperature distribution in this medium. On the basis of the developed mathematical models, a computational algorithm was created and on this basis, software tools were created, using which the heat exchange processes in the middle of the brake structures for the selected materials of the brake pads were analyzed in terms of their effectiveness, as well as the determination of the optimal temperature values for the effective operation of the braking system of vehicles. The developed linear and nonlinear mathematical models for determining the temperature field in spatial heat-active media with internal heating make it possible to analyze their thermal stability. As a result, it becomes possible to increase it and protect it from overheating, which can cause the destruction of not only individual nodes and individual elements, but also the entire structure.

Published: September 2024

A system for recognizing objects that are captured in real time on a video camera in a noisy environment that changes to the surrounding conditions has been built. The method of filling the database for mobile military objects was studied. For object recognition, the YOLO v8 neural network is used, which allows you to track moving and identify objects that fall into the video from the video camera. This neural network makes it possible to track objects with a change in scale, during movement with obstacles. It has been analyzed that the recognition of objects is carried out on the basis of contour analysis, comparison with a template and detection and matching of features. Artificial intelligence methods based on YOLO v8 were used to recognize military equipment. Trained for different YOLO models using Adam W, Adam, SGD optimizers and 512x512, 640x640, 1024x1024 px image resolution. Improved object recognition is achieved by analyzing contours, comparing patterns, and comparing entered special points. Different image resolutions and optimizers have shown different effects on model performance, and standard evaluation metrics do not provide the most accurate view. The most effective optimizer is gradient descent (SGD), which has shown the best accuracy for combat vehicle recognition. The gradient is usually considered as the sum of the gradients caused by each training element and is used to adjust the model parameters. As a result of the development of the system, indicators with recognition accuracy (accuracy) of 92%, F1-estimate (F1 score) – 89%, average indicator of accuracy (mAP) – 90% were formed. A method of filling the data set and creating a classifier is proposed. A model of combat vehicle recognition was built. Graphs, results of recognition of moving objects in the Yolo8 x neural network are presented.
Merkitsevyyden merkitys, tilastolliset rutiinit sekä metodologiset ja kognitiiviset harhat

Tilastollisten nollahypoteesien testaaminen, p-arvojen runsas raportointi, tulosten mekaaninen lajittelu tilastollisesti ”merkitseviin” ja ”ei-merkitseviin” sekä tähdittäminen kynnysarvojen (kuten 0,05) perusteella ovat suosittuja rutiineja terveystieteiden ja muidenkin alojen tutkimusraporteissa. Testaamiseen liittyy metodologisia taustaoletuksia, jotka vaikuttavat päätelmien pätevyyteen, mutta joita ei useinkaan oteta riittävästi huomioon aineistojen analyysissä ja tulosten tulkinnassa. Taustaoletukset koskevat analyysissä käytettyjä tilastollisia malleja ja havaintojenkeruunasetelmaa. Niiden pitää olla riittävässä määrin täytetyt, jotta tilastollisten tunnuslukujen nimelliset ominaisuudet pätisivät. Oletusten realistisuus on monesti kyseenalaista, jolloin tuloksiin vaikuttavat erilaiset metodologiset harhat. Lisäksi analyysiä ja tulosten tulkintaa haittaavat p-arvoihin ja luottamusväleihin liittyvät väärinkäsitykset ja kognitiiviset harhat. Testaaminen on usein liiallista, tarpeetonta, jopa rituaalinomaista ja pahimmillaan tieteen edistymistä haittaavaa. Väärintulkinnat johtavat toisinaan vakaviinkin seurauksiin. Luottamusvälien lisääntynyt raportointi on vain osin parantanut tilannetta, koska niitäkin käytetään ja tulkitaan väärin. Ongelmien taustalla on oppihistoriallisia ja institutionaalisia syitä, vääriä kannustimia, puutteita tutkijoiden menetelmäkoulutuksessa ja erityisesti tilastomenetelmien ulkokohtainen soveltaminen suhteessa tutkimuskohteeseen ja kontekstiin. Tilastotieteen valtavirran edustajat ovat eri foorumeilla tuoneet esiin näitä ongelmia ja esittäneet suosituksiaan tilastollisen analyysin ja tulostenasianmukaisen raportoinnin käytäntöihin. Artikkelissa luodataan kansainvälistä keskustelua aiheesta, tarjotaan tavanomaisia oppikirjaesityksiä täydentäviä näkökulmia p-arvojen ja luottamusvälien olemukseen, harkitumpaan käyttöön ja sävykkäämpiin tulkintatapoihin, esitellään julkaisusarjojen raportointisuosituksia, pohditaan menetelmäkoulutuksen uudistamistarpeita, ja tarkastellaan testauksen ja p-arvojen käyttöä tämän lehden viimeaikaisissa numeroissa.

Authors:   Centre of Chemical Synthesis and Polymer Technology, Institute of Science, Universiti Teknologi MARA, 40450 Shah Alam, Selangor, MALAYSIA, Mamauod Siti Nur Liyana
Published: September 2024

This investigation delves into the potential utilization of Tire Reclaimed Rubber (TRR) as a filler within Natural Rubber/Styrene Butadiene Rubber (NR/SBR) blends. TRR is obtained from discarded rubber tires and stands as a pertinent resource that necessitates its effective utilization in the production of eco-friendly, value-added rubber-based products. This is due to the rising of rubber waste tires which causes environmental concerns and all sorts of pollution. The TRR filled NR/SBR blends were fabricated using two-roll mills. The loadings of TRR were varied ranging from 20 phr to 100 phr. The aim of this study is to investigate the influence of TRR loading on the curecharacteristics and mechanical properties of blends in terms of tensile strength, rebound resilience, hardness, and density. It is found that the MH and Δ torque exhibited a decreasing trend which would indicate a reduction in crosslink density due to high loading of TRR. Meanwhile, the ts2 and tc95 increased with the increase of TRR loading. Furthermore, the tensile strength, hardness, density, and rebound resilience of blends experience a steady reduction with the incorporation of TRR. The decrement of those properties might be due to the low molecular weight of TRR. Regarding the collective findings, TRR emerges as a potentially viable candidate for waste rubber repurposing, serving as a non-reinforcing filler with optimal utility achieved at a 30 phr loading level.

Published: September 2024

The granite processing industry generates a substantial volume of residual granite waste daily. This residue is collected through a filtration process during the drying and heating stages of concrete mixture production. Utilizing this residue, known as granite fly ash (GD), offers a promising avenue for mitigating adverse effects due to this waste material. The present study undertakes an experimental investigation into the potential utilization of granite fly ash as a filler to enhance the mechanical properties of basalt/glass composites (BFRC/GFRC). The research focuses on assessing the density and tensile characteristics of the developed fibre-reinforced polymer (FRP) composites. Composite samples were fabricated by incorporating GD at varying loadings, i.e., 1 wt.%, 3 wt.%, and 5 wt.%. The FRP laminates were produced using hand lay-up and vacuum silicon mold curing techniques. The outcomes show a slight increase in density, in which a maximum of 7% increment at 5 wt% of GD in BFRC. Meanwhile, tensile properties displayedsignificant enhancements, especially FRP with 3 wt.% GD content, for both BFRC and GFRC. Notably, the addition of 1 wt.% GD resulted in a 9% increase in tensile strength and a substantial 27% increase in modulus for the BFRC composite. In summary, the study underscores the advantageous influence of GD incorporation, particularly within the 1 wt.%, 3 wt.%, and 5 wt.%, on the mechanical properties of both BFRC and GFRC composites.

Impact of bank financial technology on the performance of banks in the European Union
Authors: Garškaitė-Milvydienė Kristina , Tvaronavičienė Manuela
Published: September 2024

This article examines how financial technology determines bank performance in different EU countries. The answer to that question would allow banks to choose their development policy. The paper focuses  on the main and most popular bank services that are linked to financial technology. A SWOT analysis of FinTech is also presented to show the benefits and drawbacks of FinTech. FinTech-based services are very diverse and are provided by financial  firms and banks alike. This paper looks at the financial technology provided by banks: internet usage (internet banking), number of ATMs, credit transfers in a country, percentage of the population in a country holding a debit or credit card and whether that population has received or made a digital payment. Using the multi-criteria assessment methods of CRITIC and EDAS, the authors analysed and compared the countries of the European Union and the financial technology used in them. As a result of the application of these methods, the EU countries under consideration were ranked in terms of the use of financial technology. Subsequently, three banks from different countries with different levels of the use of financial technology were selected for the study. For these banks, financial ratios of profitability were calculated to characterise their performance. Correlation and pairwise regression analyses between the banks’ profitability ratios and financial technology were used to assess the relationship and influence between these ratios. The main conclusion of the study focuses on the extent to which financial technology influences the performance of banks in the selected countries. It is likely that further research will try to take into account the size of the country’s population when analysing all financial technologies. Researchers also needed to find out what influence financial technologies have on the such financial indicators as operational efficiency (costs), financial stability, and capital adequacy.

Published: September 2024

The covid-19 pandemic has adversely affected the sustainability of micro and small enterprises (MSEs), with a particularly pronounced impact in Central Java. Entrepreneurs who struggle to adapt to reduced consumer purchasing power and the increasing reliance on digital technology are at heightened risk of business closure. Despite these challenges, inclusivity remains a crucial element for MSEs in fostering local economic development. Accordingly, this study seeks to examine the role of inclusivity in the sustainability of MSEs that are based on digital technology. Data were collected through the use of questionnaires and focus group discussions. Respondents were digital-based MSEs entrepreneurs from five selected regions, with Central Java having the largest number of digital media users. Key informants included experts from Diponegoro University, the International Council of Small Business (ICSB), the Department of Cooperatives and Micro, Small and Medium Enterprises at the provincial and district levels, and non-governmental organizations. The collected data was analyzed using the Rapid Appraisal for Micro and Small Enterprises (Rap-MSE’s) method. To assess the sustainability status, the study utilized several dimensions, including economic, environmental, social, institutional, technological, and inclusivity factors. Both multidimensional and individual analyses indicated that the sustainability status was relatively robust. MSEs that integrated digital technology into their operations were able to withstand the challenges posed by covid-19 and adapt to the new normal. In conclusion, the inclusivity dimension in the adoption of digital technology has gained increased importance in driving local economic development.

Published: September 2024

A lo largo de la historia, la Educación Infantil ha estado a cargo de las mujeres. Esta tradición cultural ha favorecido la proliferación de estereotipos de género en relación con el cuidado de la infancia y su educación en los primeros años de vida. El hombre no ha sido bien considerado socialmente para la docencia en el nivel de Educación Infantil y este ha asumido su papel secundario en la educación de la infancia. A través de una investigación cualitativa, y mediante la implementación del método biográfico-narrativo, en el presente estudio se analizan los relatos de vida de dos varones andaluces de distinta edad y titulación (maestro de Educación Infantil y técnico en Educación Infantil) con el fin de conocer sus experiencias formativas y profesionales. El análisis de su experiencia lleva a reflexionar acerca de tres cuestiones fundamentales: el importante papel de la educación desde la infancia libre de sesgos de género; la importancia de la formación inicial para apostar por un modelo de docente comprometido con la escuela y la educación en los primeros años de vida; y la apuesta por una práctica de aula que elimine las diferencias de género.
Lógicas hegemónicas de evaluación: tensiones y contradicciones de la evaluación en la enseñanza
Authors: Sverdlick Ingrid
Published: September 2024

En el presente artículo, escrito como un ensayo, se busca aportar a la reflexión sobre los discursos y las prácticas de evaluación que abonan al pensamiento hegemónico meritocrático sobre la educación, reforzando la función conservadora de reproducción social y cultural (Bourdieu y Passeron, 1967). Se propone una reflexión sobre la evaluación en la enseñanza, en un escenario en el que la escuela parece estancada en debates infértiles sin avanzar en la construcción de un pensamiento crítico habilitante o promotor de una mirada analítica que problematice el consumo voraz y acrítico de información que proviene fundamentalmente de las redes sociales y los medios masivos de comunicación. Asimismo, se analizan las resistencias, las tensiones y contradicciones que conviven con las ideas y acciones propuestas desde un enfoque pedagógico de la evaluación como práctica valorativa y reflexiva, democrática, y cuyo sentido y funcionalidad es indisociable de la enseñanza. Como aporte para profundizar en el tema, se relata y analiza una experiencia de evaluación masiva en la Provincia de Buenos Aires que se posiciona como una política de enseñanza e interpela la lógica hegemónica de las pruebas estandarizadas.

Mechanical Twinning in Naturally and Experimentally Deformed Diopside
Authors: Raleigh C. B. , Talbot James L.
Published: September 2024

Lamellar twinning on (100) and to a lesser extent on (001) are present in clinopyroxenes of deformed mafic and ultramafic rocks. Both sets of twins are mechanical in origin and form where the resolved shear stress on the twin-glide system is high. Statistically, compression axes most favorably oriented for twin gliding in each of a large number of grains are aligned sub-parallel to the direction of maximum compression in experiments. In some deformed diopside-bearing calc-silicate rocks from South Australia, compression and tension axes deduced from twinning are consistent with principal stresses deduced from faulting. It is concluded that lamellar twinning in clinopyroxenes may be used for determination of the direction of principal stresses in natural deformations of rocks.
Origin of Jove Peak Orbiculite in Wenatchee Ridge Area, Northern Cascades, Washington
Authors: VanDiver Bradford B.
Published: September 2024

The sill-like, metagabbroic Jove Peak Orbiculite intruded the Chiwaukum Schist during the Skagit metamorphism, and was later intruded by quartz diorite. Orbicules of hornblende nucleated on pyroxene or hornblende phenocrysts, or on xenoliths of gabbro, hornblendite(?), pyroxenite(?), mica schist, and amphibolite. The igneous origin of the orbicules is shown, and other characteristics clearly indicate post-orbicular recrystallization. The orbiculite matrix contains abundant relict igneous features. Subsequent medium-grade metamorphism is shown. This dual igneous-metamorphic origin (as opposed to migmatitic) is also shown by bimodal plagioclase composition and by remarkable compositional differences in plagioclase across interfingering mica-schist-orbiculite contact.
Isotope Hydrology of Early Paleogene Lake Flagstaff, Central Utah: Implications for Cordilleran Evolution
Authors: VanDeVelde Justin H. , Bowen Gabriel J.
Published: September 2024

Lacustrine sediments from Paleogene foreland basins of the North American Cordillera serve as powerful integrators of information on climatic and tectonic conditions, but episodes of hydrologic connection between basins may confound straightforward interpretations. We use stable isotope ratios of carbon and oxygen in authigenic carbonates of the Flagstaff Formation in central Utah to investigate the history of the lake system which produced these sediments. Flagstaff limestone and dolostone exhibit isotopic compositions consistent with having formed from the same fluid at surface conditions, indicating high evaporative concentration was unnecessary to drive dolomite precipitation. Isotopic data are consistent with the Flagstaff Formation having been produced by a large lake which occupied its basin from the late Paleocene into the early Eocene. Lake Flagstaff was hydrologically distinct from Lake Uinta to the north, but may have been connected to Lake Claron in the south. Paleoaltimetry estimates suggest that the mean elevation of Lake Flagstaff9s catchment in the Sevier Highlands did not exceed 1.5 km. The growing evidence from stable isotope data that Cordilleran elevations were relatively low in the early Paleogene is in stark contrast to structural and sedimentological evidence for a high Nevadaplano and a topographically rugged Sevier thrust belt.

The main purpose of the existing study is to present the mediating influence of employee performance on the relationship between transformational leadership style and green innovation. This study conducted in the hotel sector in Amman, Jordan, where exploratory studies related to the hotel sector are limited. A total of 20 five-star hotels in Amman were involved in the research sampling process, targeted respondents were employees with titles below supervisor level (rank-and-file) were those employees who provide the services and are in direct contact with customers, and a simple random sampling was utilized to gather the data, 359 employees participated in this study, and survey form was sent to heads of departments at the targeted hotels to help in the distribution process. The data was analyzed using Smart-PLS software. The results showed a partially positive mediation of employee performance among both constructs of individualized consideration and intellectual stimulation of green innovation in the hotel sector. Moreover, these results proved the power of the relationship between employee performance and the adoption of green innovation. The current study contributes positively to the area of hospitality industry studies and its related activities. It provides better insights for hotel leaders on improving the adopted leadership styles, leading to outstanding employee performance, and green innovation to sustain market competitiveness and provide exceptional and innovative services for a better hospitality industry.

Authors: Budac Camelia , Ilie Livia
Published: September 2024

In recent years, in order to stimulate economic growth, the importance of innovation and entrepreneurship has been increasingly recognized by practitioners and teaching staff. Universities must contribute to this growth, as a center of knowledge creation and a center of research. However, transforming academic research into marketable products and services faces significant challenges. Addressing these challenges has necessitated the emergence of academic incubators as an essential mechanism for providing resources, support, and an environment suitable for the development of startups. Thus, academic incubators are becoming an essential component of a university in order to recruit and retain students, instructors, and researchers with an entrepreneurial mindset, as well as to stay exposed to students who are becoming more and more interested in starting enterprises or social projects. In these conditions, the present paper aims to provide an overview of the role of academic incubators in stimulating innovation and entrepreneurship in universities, emphasizing their role, functions and impact in the socio-economic environment.
