Almaty and its environs are located in the foothill zone of the Zailiysky Alatau, where, given the lack of sites with good soils, many buildings and structures have to be built on weak soils, weak clay or subsidence bases. Another problem is construction in seismically active areas, which imposes certain restrictions on the design of foundations and the construction of structures. In such cases, specialized engineering measures are required, whether it is soil replacement, pile foundations or artificial foundations. In construction, there is a wide range of methods for fixing soils: strengthening with piles, vertical reinforcing elements, chemical fixing with solutions that allow you to carry out activities. This article describes the methods and sequence of work when using a two-component polyurethane material GEOPUR. In laboratory and field conditions to increase the bearing capacity of soils. The result of the application of this technology is a triple effect: increased moisture resistance and sealing; stopping or reducing water inflow to underground structures; stabilizing soil cementation - increasing the stability of the foundations of buildings and underground structures; there is a structuring and strengthening of soil, rocks and structures. Due to the introduction of the Geopur® material, soil structuring occurs, and it passes from the class of dispersed to the class of semi-rocky soils, the strength of which is characterized by the uniaxial compressive strength R. Studies have shown that the value of R in depth varies from 1.94MPa at a depth of 0.9m up to 4.57 MPa at a depth of 4.20 m. In accordance with state standard 25100-2011, such material belongs to a variety of soils with low or reduced strength.

Számos kutatás bizonyítja, hogy a kiszolgáltatott társadalmi csoportok korlátozott választási lehetőségekkel szembesülnek, amikor oktatási vagy munkaerőpiaci lehetőségekről döntenek. Döntéseiket számos tényező – mint az etnikai háttér, családi körülmények, korábbi iskolák – erősen meghatározza, és korlátozza őket abban, hogy a lehetőségek szélesebb körét azonosítsák. A tanulmány egy 2021–2022-ben végzett kvalitatív kutatás 40 alanyából arra a kilencre koncentrál, akik stabil munkaerőpiaci pozícióra tettek szert. A képességszemlélet (capability approach) elméleti megközelítésének gyakorlati alkalmazásával feltárulnak az észlelt és a valós lehetőségtér közötti eltérések, a sikeresnek tekintett interjúalanyok narratívái alapján pedig definiálhatók azok a „perspektívaváltások” és azokhoz kapcsolódóan a speciális pécsi intézményi környezetben megjelenő tényezők, amelyek segítségével ezek az eltérések csökkennek, és amelyek következményeként a relatív munkaerőpiaci sikerekhez vezető utak váltak elérhetővé. A kilenc interjúalanyt három csoportba sorolva válik könnyebben érthetővé a perspektívaváltásban a család szerepe, és ezáltal az interjúalanyok döntései mögötti érdemi különbségek. Ugyanakkor mind a kilenc interjúalany esetében megfigyelhető két, a többi interjúalanytól megkülönböztető közös faktor: a válságok idején is folyamatosan dolgozó szülők, akik direkt vagy indirekt mintát biztosítottak; valamint a pécsi intézményrendszer kríziseken átvezető szerepe, különösen a Gandhi Gimnázium és egyes civil szervezetek esetében. Utóbbiak kiemelik Pécsnek mint a magyarországi viszonylatban a humán szolgáltatásokkal kiemelkedően ellátott nagyvárosnak a szerepét.
The Influence of the Financial System on the Puzzle of Corporate Financing Decisions: Review
Authors: ROGÃO Márcia Cristina Rêgo
Published: April 2024

The main purpose of this study is to conduct a literature review on the influence of country-specific characteristics of financial systems on corporate financing decisions, to help complete the complex puzzle on the problematic of capital structure theories. Recently, several international studies have analysed the convergence of firms’ financing decisions according to countries’ financial system, but, in terms of literature review, it becomes necessary to establish the interconnection between the explanatory theories of capital structure and empirical studies in explaining the financing behaviour of firms in different countries. Following this, the methodology of this paper was based on summarizing the empirical literature in a non-systematic way, verifying in several international studies that the capital structure is influenced by the specific characteristics of the country’s financial system, in which the efficiency of the function of financial intermediaries contributes to reducing transaction and information costs, helping to complete the understanding about the similarities and differences in the financing choices of firms in different countries.

A preservação da saúde dos indivíduos é uma das prioridades do estado brasileiro, posto que a dignidade humana depende de serviços públicos de qualidade. Diz a Constituição Federal de 1988 que esse é um dos direitos sociais apresentados no caput do artigo 6º. Na prática, esse direito é objeto de fornecimento em hospitais públicos e particulares mediante a atuação de profissionais da medicina e enfermagem, todos eles contratados e remunerados para prestarem seus serviços da melhor maneira possível. Assim, compete-lhes atuarem de forma adequada ao caso proposto, tomando os cuidados que a situação exige, visando a cura ou melhor tratamento possível. Todavia, existem situações em que o paciente dá entrada em hospital para realizar determinado procedimento estético e acaba sendo acometido por dano inexistente, seja decorrente de um caso inesperado, seja pelo equívoco no atendimento. Essas situações devem ser evitadas, especialmente porque a vida é o bem mais precioso de um ser humano. Por todo o exposto, esta pesquisa científica analisa a responsabilidade civil dos médicos brasileiros, através de pesquisa bibliográfica, apontando ainda a apuração via processo ético administrativo, para ao final apontar a possibilidade de fixação de indenização ao paciente vítima de erro médico.

Technical Note: A technique to convert NO2 to NO2− with S(IV) and its application to measuring nitrate photolysis
Authors: Lieberman Aaron , Picco Julietta , Onder Murat , Anastasio Cort
Published: April 2024

Abstract. Nitrate photolysis is a potentially significant mechanism for “renoxifying” the atmosphere, i.e., converting nitrate into nitrogen oxides – nitrogen dioxide (NO2) and nitric oxide (NO) – and nitrous acid (HONO). Nitrate photolysis in the environment occurs through two channels which produce (1) NO2 and hydroxyl radical (⚫OH) and (2) nitrite (NO2-) and an oxygen atom (O(3P)). Although the aqueous quantum yields and photolysis rate constants of both channels have been established, field observations suggest that nitrate photolysis is enhanced in the environment. Laboratory studies investigating these enhancements typically only measure one of the two photo-channels, since measuring both channels generally requires separate analytical methods and instrumentation. However, measuring only one channel makes it difficult to assess whether secondary chemistry is enhancing one channel at the expense of the other or if there is an overall enhancement of nitrate photochemistry. Here, we show that the addition of S(IV), i.e., bisulfite and sulfite, can convert NO2 to NO2-, allowing for measurement of both nitrate photolysis channels with the same equipment. By varying the concentration of S(IV) and exploring method parameters, we determine the experimental conditions that quantitatively convert NO2 and accurately quantify the resulting NO2-. We then apply the method to a test case, showing how an ⚫OH scavenger in solution prevents the oxidation of NO2- to NO2 but does not enhance the overall photolysis efficiency of nitrate.
Comparison of the imaginary parts of the atmospheric refractive index structure parameter and aerosol flux based on different measurement methods

Abstract. The complexity of aerosol particle properties and the diversity of characterizations make aerosol vertical transport flux measurements and analysis difficult. Although there are different methods, such as aerosol particle number concentration flux and aerosol mass flux based on the eddy covariance principle as well as aerosol mass flux measurements based on the light-propagated large-aperture scintillation principle, there is a lack of mutual validation among the different methods. In this paper, a comparison of aerosol mass flux measurements based on the eddy covariance principle and aerosol mass flux measurements based on the light-propagated large-aperture scintillation principle is carried out. The key idea of aerosol mass flux measurements based on the light-propagated large-aperture scintillation principle is the determination of the imaginary part of the atmospheric equivalent refractive index structure parameter (AERISP). In this paper, we first compare the AERISPs measured by two different methods and then compare the aerosol mass vertical transport fluxes obtained by different methods. The experiments were conducted on the campus of the University of Science and Technology of China (USTC). A light propagation experiment was carried out between two tall buildings to obtain the imaginary and real parts of the AERISPs for the whole path, which in turn can be used to obtain the aerosol vertical transport flux. An updated visibility meter is installed on the meteorological tower in the middle of the light path, which is utilized to obtain the single-point visibility, which is then converted to the imaginary part of the atmospheric equivalent refractive index (AERI). The imaginary parts of the AERISP were obtained via spectral analysis with visibility data. The results show that the imaginary parts of the AERISPs obtained by different methods are in good agreement. The imaginary part of the AERI measured by the visibility meter and the vertical wind speed obtained by the ultrasonic anemometer were used for covariance calculations to obtain the aerosol vertical transport flux. The trends in aerosol vertical transport fluxes obtained by the different methods are consistent, and there are differences in some details, which may be caused by the inhomogeneity in the vertical transport of aerosol fluxes. The experimental results also showed that urban green land is a sink area for aerosol particles.
Utilising a multi-proxy to model comparison to constrain the season and regionally heterogeneous impacts of the Mt Samalas 1257 eruption
Authors: Wainman Laura , Marshall Lauren R. , Schmidt Anja
Published: April 2024

Abstract. The Mt Samalas eruption, thought to have occurred in summer 1257, ranks as one of the most explosive sulfur-rich eruptions of the Common Era. Despite recent convergence, several dates have been proposed for the eruption ranging between 1256–1258, with, as of yet, no single combination of evidence that has been able to robustly distinguish between and exclude the other dates proposed for the Mt Samalas eruption. Widespread surface cooling and hydroclimate perturbations following the eruption have been invoked as contributing to a host of 13th century social and economic crises, although regional-scale variability in the post-eruption climate response remains uncertain. In this study we run ensemble simulations using the UK Earth System Model (UKESM1) with a range of eruption scenarios and initial conditions in order to compare our simulations with the most complete globally resolved multi-proxy database for the Mt Samalas eruption to date, incorporating tree rings, ice cores, and historical records. This allows more precise constraints to be placed on the year and season of the Mt Samalas eruption, as well as an investigation into the regionally heterogeneous post-eruption climate response. Using a multi-proxy to model comparison, we are able to robustly distinguish between July 1257 and January 1258 eruption scenarios, where the July 1257 ensemble simulation achieves considerably better agreement with spatially averaged and regionally resolved proxy surface temperature reconstructions. These reconstructions suggest the onset of significant cooling across Asia and Europe in 1258 and thus support the plausibility of previously inferred historical connections. Model-simulated temperature anomalies also point to severe surface cooling across the Southern Hemisphere with as of yet unexplored historical implications for impacted civilisations. Model simulations of polar sulfate deposition also reveal distinct differences in the timing of ice sheet deposition between the two simulated eruption dates, although comparison of the magnitude or asymmetric deposition of sulfate aerosol remains limited by large inter-model differences and complex intra-model dependencies. Overall, the multi-proxy to model comparison employed in this study has strong potential in constraining similar uncertainties in eruption source parameters for other historical eruptions for which sufficient coincident proxy records are available, although care is needed to avoid the pitfalls of model–multi-proxy comparison.
Non-negligible impact of Stokes drift and wave-driven Eulerian currents on simulated surface particle dispersal in the Mediterranean Sea

Published: April 2024

Abstract. Numerical simulations of marine surface particle dispersal are a crucial tool for addressing many outstanding issues in physical oceanography with societal relevance, such as marine plastic pollution. However, the quality of these Lagrangian simulations depends on the ability of the underlying numerical model to represent the prevailing ocean circulation features. Here, we investigate how simulated marine surface particle dispersal changes, if the – often omitted or only approximated – impact of wind-generated surface waves on the upper ocean circulation is considered. We use velocity fields from a high-resolution coupled ocean-wave model simulation and a complementary stand-alone ocean model simulation for the Mediterranean Sea to answer the following questions: 1) How does the explicit representation of waves impact the simulated surface particle dispersal, and what is the relative impact of Stokes drift and wave-driven Eulerian currents? 2) How accurately can the wave impact be approximated by the commonly applied approach to advect particles with non wave-driven Eulerian currents and Stokes drift from stand-alone ocean and wave models? We find that the representation of surface waves tends to increase the simulated mean Lagrangian surface drift speed in winter through a dominant impact of Stokes drift, and to decrease the mean Lagrangian surface drift speed in summer through a dominant impact by wave-driven Eulerian currents. Furthermore, simulations that approximate the surface wave impact by including the Stokes drift (but ignoring the wave-driven Eulerian currents) do not necessarily yield a better estimate of the surface particle dispersal patterns with explicit representation of the wave impact than simulations that do not include any surface wave impact. Our results imply that – whenever possible – velocity fields from a coupled ocean-wave model should be used for surface particle dispersal simulations.
A protocol for model intercomparison of impacts of Marine Cloud Brightening Climate Intervention

Published: April 2024

Abstract. A modeling protocol is introduced (defined by a series of model simulations with specified model output). The protocol is designed to improve understanding of climate impacts from Marine Cloud Brightening (MCB) Climate Intervention. The model simulations are not intended to assess consequences from a realistic MCB deployment intended to achieve specific climate targets but instead to expose responses produced by MCB interventions in 6 regions with pervasive cloud systems that are often considered as candidate regions for such a deployment. A calibration step involving simulations with fixed sea surface temperatures is first used to identify a common forcing, and then coupled simulations with forcing in individual regions and combinations of regions are used to examine climate impacts. Synthetic estimates constructed by superposing responses from simulations with forcing in individual regions are considered as a means to approximate the climate impacts produced when MCB interventions are introduced in multiple regions. A few results comparing simulations from 3 modern climate models (CESM2, E3SMv2, UKESM1) are used to illustrate similarities and differences between model behavior and the utility of estimates of MCB climate responses that have been synthesized by summing responses introduced in individual regions. There are substantial differences in the cloud responses to aerosol injections between models, but the models often show strong similarities in precipitation and surface temperature response signatures when forcing is imposed with similar amplitudes in common regions.

Published: April 2024

Abstract. Fungal spore organic aerosol emissions have been recognised as a significant source of particulate matter as PM10; however, they are not widely considered in current air quality models. In this work, we have implemented the parametrisation of fungal spore organic aerosol (OA) emissions introduced by Heald and Spracklen (2009) (H&S) and further modified by Hoose et al. (2010) in the CHIMERE regional chemistry-transport model. This simple parametrisation is based on two variables which are leaf area index (LAI) and specific humidity. We have validated the geographical and temporal representativeness of this parametrisation on a large scale by using yearly polyol observations and primary biogenic organic aerosol factors from PMF analysis at 11 French measurement sites. For a group of sites in northern and eastern France, the seasonal variation of fungal spore emissions, displaying large summer and small winter values, is correctly depicted. However, the H&S parametrisation fails to capture fungal spore concentrations for a smaller group of Mediterranean sites with less data availability both in terms of absolute values as well as seasonal variability, leading to strong negative biases especially during the autumn and winter seasons occur. Two years of CHIMERE simulations with the H&S parametrisation have shown a significant contribution of fungal spore OA to PM10 mass, lower than 10 % during winter, and reaching up to 20 % during summer in high emission zones, especially over large forested areas. In terms of contribution to organic matter (OM) concentrations, the simulated fungal spore contribution in autumn is as high as 40 % and reaches at most 30 % of OM for other seasons. As a conclusion, the fungal spore OA contribution to total OM concentrations is shown to be substantial enough to be considered as a major PM10 fraction and shall then be included in state-of-the-art chemistry transport models. The H&S parametrisation shows satisfactory results over northern and eastern France, but may underestimate concentrations for Mediterranean areas that may indicate missing factors influencing emissions or a missing source of spores.

Abstract. Atmospheric aerosol in the Tibetan Plateau (TP) and its surroundings has attracted significant scientific interest in recent decades due to its notable impacts on regional climatic and cryospheric changes, ecological and environmental security, and the hydrological cycle. However, our understanding of the atmospheric aerosol in this remote region is highly limited by the scarcity of available datasets owing to the extremely harsh natural conditions. This challenge has been mitigated in recent decades by establishing field observatories at typical sites within the TP and its surroundings. A continuous project initiated in 2015 aims to explore the properties and sources of atmospheric aerosols, as well as their regional differences, through multiple short-term intensive observations obtained across this vast region utilizing a suite of high-time-resolution online instruments. This paper presents a systematic and hourly scale dataset of aerosol physicochemical and optical properties at eight sites across the TP and its surroundings that is derived from the project. It includes size-resolved chemical compositions of submicron aerosols, high-resolution mass spectra and sources of organic aerosols, size distributions of particle number concentrations, particle light-scattering and light-absorption coefficients, particle light absorptions attributed to different carbonaceous substances including black carbon and brown carbon, and number concentrations of cloud condensation nuclei. In brief, atmospheric aerosols in these remote sites were all well mixed and highly aged, reflecting their dominant regional transport sources. However, the southern TP region exhibited high contributions of carbonaceous organic aerosols, neutralized bulk submicron aerosols, and a relatively high light-absorption capacity, whereas in the northern TP region, secondary inorganic species were the main contributors to the overall acidic submicron aerosols. Beyond providing insights into the regional differences in aerosol sources and properties across the TP and its surroundings, the datasets will also benefit simulations of aerosol radiative forcing and evaluations of interactions among different Earth system components in numerical models for this region. The datasets are accessible through the National Cryosphere Desert Data Center, Chinese Academy of Sciences (https://doi.org/10.12072/ncdc.NIEER.db2200.2022; Xu, 2022).

Democracia, educação e diferença: na contracorrente das políticas neoliberais e neoconservadoras
Authors: Voss Dulce Mari da Silva , Krakhecke Eliada Mayara Alves , Jacondino Eduardo Nunes
Published: April 2024

Neste artigo, efetua-se uma análise da aliança hegemônica neoliberal e neoconservadora no campo social, político e econômico global, o que gera fortes impactos também na educação. Pretende-se fomentar o pensamento em torno de possíveis articulações entre democracia, educação e diferença, a partir da operacionalização de conceitos elaborados por Ernesto Laclau, Chantal Mouffe e Judith Butler. Compreende-se que as políticas são produzidas em relações de poder conflitivas e antagônicas entre demandas diferenciais. A aliança hegemônica neoliberal e neoconservadora decorre da articulação entre essas demandas diferenciais que se tornam equivalentes e passam a compor o interior constitutivo da ordem estabelecida. Nela, não são contempladas demandas sociais que advogam por justiça e direito à educação, o que as faz o exterior constitutivo desse jogo político. Trata-se da produção discursiva da democracia interrelacionada à educação e à diferença como totalidade que serve à aliança neoliberal e neoconservadora do sistema capitalista. No entanto, qualquer totalidade será sempre parcial, precária e contingente. O desafio posto seria pensar na democracia radical, aberta às diferentes demandas, as quais, no jogo de disputas políticas, permanecem como exterior constitutivo do projeto hegemônico. Isso porque a democracia radical permite compreender e criar outras cadeias de equivalências que podem projetar e disputar com mais força as lutas contra-hegemônicas.

Published: April 2024

Foreign direct investment (FDI) is considered a significant tool to transform modern technologies and innovation from developed to developing countries. Unfortunately, some countries impose FDI restrictions for economic, political, and social reasons. The present study assesses the role of different restrictive policies on FDI inflows in OECD and non-OECD countries. The empirical results are estimated by using panel quantile regression (PQR) at the median quantile from 1998 to 2022. It uses the all-restrictiveness policies index and its four subtypes: equity, key foreign personnel, screening and approval, and operational restrictions; the data is extracted from the OECD database. The study concluded that all restrictiveness policy indexes and their subtypes in OECD countries propose the inverted U-shaped curve. In contrast, in non-OECD countries, it shows the U-shaped relationship to determine the FDI inflows. Furthermore, this study also examines the individual countries using the marginal effect. In OECD countries, Australia, Canada, Mexico, and New Zealand have imposed higher restrictions, which reduces the FDI, while in non-OECD countries case, China, Indonesia, Malaysia, and the Philippines imposed higher restrictions, which increased FDI inflows. This study recommends that OECD countries reduce the FDI restrictiveness policies while non-OECD countries should increase it.

Published: April 2024

The lack of resources in the modern world necessitates the reorganisation of the conventional linear economy into a new, circular model of economic development, and this requirement is even more urgent for a country at war. The purpose of this study was to prove the necessity and possibility of achieving sustainable development goals even in a crisis, using evidence from Ukraine. Using such methods as statistical analysis, comparison, and synthesis, the dynamics of sustainable development in the European Union and Ukraine were investigated. In addition, relevant experts were interviewed via an online survey. The study obtained and analysed statistics on the transition of European countries to clean energy sources, conducted a detailed investigation of the current legislative framework and state institutions of Ukraine related to recycling war waste, strengthening the digitalisation of Ukrainian society, and studied wartime circular recycling measures. Statistics on the factual destruction and pollution of the environment as a result of hostilities and the temporary occupation of some territories were also examined. Furthermore, information was collected and systematised from the management of Ukrainian manufacturing enterprises on the factual implementation of circular economy principles during the war. The analysis of the data obtained led to the conclusion that the crisis only increases the need to save resources. The practical significance of the study lies in proving that there is no alternative to the goals of sustainable development in the future and emphasising Ukraine’s competitive advantages in this area during the post-war reconstruction. These proposals will be useful for private investors who can profitably finance Ukraine’s future recovery in line with the principles of the circular economy

Published: April 2024

The integration of digital technologies in the financial industry holds significant promise for enhancing the effectiveness and availability of financial services. However, it is also confronted with various financial and organisational limitations that must be resolved. The objective of this study is to examine the financial and organisational limitations that occur during the implementation of digital technologies in financial management. In order to accomplish this objective, various techniques such as analysis, synthesis, generalisation, systematisation, and statistical methods were employed. The study revealed that the implementation of digital technologies in the financial sector encounters substantial obstacles and constraints. An inherent challenge arises from the incongruity between emerging digital technologies and antiquated traditional management models, resulting in deficiencies and vulnerabilities in organisational management. The study emphasises the significance of organisations modifying their management models in order to achieve optimal utilisation of digital tools. The findings also demonstrate the significance of organisational elements such as culture, competencies, digital resources, senior management support, and organisational structure in shaping choices to embrace and execute digital technologies. Thus, the study helps to solve current issues related to the introduction of digital technologies in the financial sector and contributes to improving its efficiency and sustainability. The practical significance of the study is to increase the understanding of financial and organisational constraints that arise during the introduction of digital technologies in financial management and to contribute to the development of more effective approaches to digital financial management

There is a need for scientific validation of the claim that wild species of medicinal plants are more potent than cultivated plants. Tinospora cordifolia is a prominent medicinal plant used for diverse pharmacological activities. Current study evaluates Pharmacognostical and phytochemical analysis, total flavonoids, as well as the antioxidant activity of T. cord folia’s stem extract collected from Kanha Shanti Vanam. Hyderabad. The stem powder was extracted by a method involving the usage of 96% of ethanol and evaporated by a rotary evaporator to obtain the extract. Physiochemical, microscopic, phytochemical analysis and fingerprinting were done by employing a CAMAG HPTLC. The spectroscopic approach was also used to estimate the flavonoid concentration in relation to quercetin. 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay has been used to assess the antioxidant potential of the plant. The findings confirm that methanolic extracts of T. cordifolia stem powder from the region showed higher secondary metabolites, and it also indicates that the methanolic extracts of the stem are a potential source of antioxidants which may be due to the presence of flavonoids in the extracts. The study also reveals the potency of standardised extracts of T. cordifolia growing at Kanha Shanti Vanam can be developed as an antioxidant herbal medicine.

Nasal anthropometry is among the best clues to racial origin and sexual determination. The nose's shape and structure differ between genders, races, and ethnicities. The understanding of nasal anthropometry is applied in forensic medicine, nasal reconstruction surgery, and naso-facial dysmorphology identification. This research aimed to investigate the anthropometry of the external noses among Malay and Chinese university students in Sarawak. A total of 80 university students (40 males and 40 females) aged between 18 and 25 participated. The nasal height, length, width, and philtrum length were measured anthropometrically using a slide calliper. Malay males had significantly more nasal width than females (p<0.05). Nasal width, philtrum length, and nasal index were significantly higher in males than female Chinese students (p<0.05). The philtrum length was significantly longer in Chinese students than in Malays (p<0.05). Further study can be done by using a larger sample size to obtain a better representation of the particular ethnicities. In conclusion, sexual dimorphism and ethnic differences can be observed in the anthropometry of the external noses among Malay and Chinese in Sarawak.

Published: April 2024

WHO disability statistics indicate that about 8 million people worldwide, or 1% of the total population, suffer from a mobility handicap. It is also known that the elderly residents in the area cannot move independently. Many hospital patients can force their hand with assistance but cannot move independently. We also understand that real-time health monitoring is necessary for patients, the elderly, and individuals with impairments. Therefore, this work aims to develop and provide a smart wheelchair that can be controlled with a single hand gesture and tracks many health indicators, such as blood pressure, body temperature, oxygen saturation, and pulse rate, using an Internet of Things-based real-time health monitoring system. Users can effortlessly maneuver the wheelchair using simple gesture control enabled by the Internet of Things (IoT), promoting independence and enhancing general well-being. This innovative approach to healthcare and mobility meets users' urgent requirements and establishes a new benchmark for assistive technology, a significant advancement in technology and healthcare. The benefit of this strategy is that the caregiver can view all of these health indicators and the wheelchair user's GPS location using a smartphone application. Taking care of oneself while employed by a firm might be easy.
A Machine Learning Approach on Data-Driven Thermal Monitoring of Induction Motors in Electrified Powertrains
Authors: Dexter Woodward
Published: April 2024

The research is aimed to determine a data-driven approach towards the thermal monitoring of Induction Motors in the context of electrified powertrains. We apply the examination of the temperature data with the help of the appropriate set of sensors, including Thermocouples, Resistance Temperature Detectors , as well as Infrared sensors in combination with the mixture of the Machine Learning algorithms to predict the service requirements and operational needs of the examined system . The data, provided by the thermal sensors, makes it possible to predict the demand for the maintenance of the part or optimize the work of the coolant pumps. Thus, we conduct the performance analysis of several ML models, including Artificial Neural Networks , Support Vector Machines , Decision Trees , and Random Forests across the range of different epochs of the training. Our analysis has shown that ML-based approaches can be highly efficient in accurately predicting the forthcoming maintenance requirements using the sensor-based information. Precisely, the most efficient was the ANN model, producing the result of 97.65%. It was followed by SVM and DT, producing the results of 94.5% and 92.3%, respectively. Finally, RF was only able to produce the result of 90.25%, falling behind the other approaches. Our comparison has provided multiple implications to the relative strengths and weaknesses of the employed models, and the choice of whether they are appropriate must be conducted through the prism of these comparisons. In addition, the analysis of the performance across different epochs has shown that the subsequent ones have produced the better results, which makes the training process crucial.
Hybrid Random Forest Regression and Artificial Neural Networks for Modelling and Monitoring the State of Health of Li-Ion Battery

Published: April 2024

Lithium-ion batteries play a significant role in modern energy storage systems for a number of applications, including renewable energy installations, electric cars, and portable devices. In order to guarantee the long-term dependability and safety of these battery packs, comprehensive modelling and monitoring approaches are required for accurate State of Health (SoH) evaluation. This research suggests an innovative strategy that combines the strengths of Random Forest Regression (RFR) and Artificial Neural Networks (ANN) for reliable Li-ion battery SoH modelling and monitoring. The research starts with the collection of thorough Li-ion battery data, which includes voltage, current, temperature, and cycling characteristics.  The battery dataset's nonlinear relationships are captured utilising RFR as the main modelling method. In terms of feature selection and prediction precision, RFR's ensemble of decision trees shines, making it a strong contender for modelling complex battery behaviour. The SoH prediction is then enhanced by the use of ANN, a deep learning framework renowned for its ability to extract detailed patterns from data. The characteristics of RFR are complemented by ANN's capacity to discover hidden features and nonlinear correlations, improving the overall prediction performance. The suggested hybrid approach, that combines RFR and ANN, is trained and verified utilising a diverse database acquired from  Li-ion battery sources under operational circumstances. To assess the prediction accuracy of a suggested framework measures like Mean Absolute Error (MAE), Root Mean Square Error (RMSE), and R-squared (R2) values are employed. The outcomes show that the hybrid RFR-ANN model works better than the individual RFR and ANN models, producing better SoH predictions. A viable solution for real-time Li-ion battery health monitoring is provided by this combination of conventional ML and deep learning approaches, which demonstrates the synergy among complexity and interpretability. This research advances battery SoH assessment and paves the way for the practical incorporation of precise monitoring systems into applications like electric vehicles, where timely and accurate SoH data is essential for maximising battery performance and extending operational lifespan.
