Scalable Neural-Probabilistic Answer Set Programming
Authors: Skryagin Arseny , Ochs Daniel , Dhami Devendra Singh , Kersting Kristian
Published: November 2023

The goal of combining the robustness of neural networks and the expressiveness of symbolic methods has rekindled the interest in Neuro-Symbolic AI. Deep Probabilistic Programming Languages (DPPLs) have been developed for probabilistic logic programming to be carried out via the probability estimations of deep neural networks (DNNs). However, recent SOTA DPPL approaches allow only for limited conditional probabilistic queries and do not offer the power of true joint probability estimation. In our work, we propose an easy integration of tractable probabilistic inference within a DPPL. To this end, we introduce SLASH, a novel DPPL that consists of Neural-Probabilistic Predicates (NPPs) and a logic program, united via answer set programming (ASP). NPPs are a novel design principle allowing for combining all deep model types and combinations thereof to be represented as a single probabilistic predicate. In this context, we introduce a novel +/− notation for answering various types of probabilistic queries by adjusting the atom notations of a predicate. To scale well, we show how to prune the stochastically insignificant parts of the (ground) program, speeding up reasoning without sacrificing the predictive performance. We evaluate SLASH on various tasks, including the benchmark task of MNIST addition and Visual Question Answering (VQA).

Published: November 2023

In construction projects in Khuzestan province in Iran, electric-arc steel slag (EASS) materials are used as fill materials. In this research study, bio-cementation practice on EASS materials is examined and compared with that on natural sand. For this purpose, direct shear, unconfined compressive strength (UCS) and constant head permeability tests, together with scanning electron microscopy images obtained using an instrument equipped with an energy-dispersive X-ray spectroscope, were used to analyse and compare untreated and treated materials. The results showed that despite higher urease activity and higher calcite production of EASS materials compared with natural sand, the latter showed slightly higher UCS, higher cohesion intercept enhancement and higher permeability decrease after bio-cementation treatment.
İslâm Hukukunda Otizmli Bireylere İlişkin Hükümler
Authors: Bozbaş Fatiha
Published: November 2023

Klinik belirtiler göz önünde bulundurulduğunda otizm, daha ziyade sosyal-iletişimsel alanda sınırlılık ve yetersizlikle ilişkili sorunları ortaya çıkarmakta ve bu yönüyle otizmli bireyler daha çok psikoloji, tıp ve eğitim bilimlerinin inceleme konusu olmaktadır. Bununla birlikte bu tür hastaların önemli bir kısmında zihinsel yetersizlik bulunmaktadır. Bu durum düşük fonksiyonlu otizmli bireyleri hukukî kişi olarak tanımlanmaları, hukuken yetkileri, sorumlulukları ve sınırlılıkları hususunda hukukun ve fıkhın konusu haline getirmektedir. Bu çalışmada düşük fonksiyonlu otizmli bireylerin İslam hukuku çerçevesinde şer’î hükümlere muhatab olma durumları incelenecektir. Bu minvalde gerek ibadetler alanında, gerekse medenî hukuk ve ceza hukuku alanındaki hukukî ehliyetleri izah edilerek genel bazı fıkhî hükümlere yer verilecektir. Genel bir perspektifle bakıldığında; bulgularına zihinsel yetersizlik eşlik eden otizmli bireylerin fıkhî durumlarının klasik fıkıh literatüründe ele alınan ehliyet arızaları (عوارض الأهلية) konusu ile birlikte değerlendirilmesi mümkün gözükmektedir. Literatürde husûsen sürekli akıl hastalığı (الجنون) ve kısmî bunama (العته) olmak üzere iki kavram çerçevesinde izah edilen ilgili hükümler, bu tür bireylerin fıkhî durumlarına ışık tutmaktadır.

Butadiene is the main monomer used in modern industrial production of general purpose synthetic rubber. Currently, up to 99 % of butadiene-1,3 is obtained during oil refining, however, due to hydrocarbon reserve depletion, the search for alternative methods for butadiene-1,3 obtaining from renewable resources is an urgent task. One of the most promising renewable sources of raw materials is ethanol. Currently, this process is unprofitable due to low selectivity for the target butadiene. Therefore, in this work, an attempt was made to create a new heterogeneous catalyst that allows increasing the selectivity of the process of obtaining butadiene-1,3 from ethanol. In general, in the promising and demanded products production based on butadiene on the global market, the consumption of monomer from 2010 to 2030 should increase by 2 times from 526 to 1235 thousand tons per year. With a projected butadiene productivity of 1038 thousand tons per year, the deficit by 2030 will remain at the level of 200 thousand tons per year, which can be eliminated in two ways: by successful implementation of the Russian Gas and Petrochemical Development Plan for the period up to 2030, taking into account the weighting of pyrolysis raw materials with priority on naphtha; thanks to the development and introduction of new butadiene production methods as the target product. Therefore, this work is devoted to butadiene production from alternative raw materials on effective heterogeneous catalysts.
Custom in Action. Ferdinand Tönnies’ Ontology of the Normative
Authors: Presi Virginia
Published: November 2023

This paper deals with custom in action, namely, with the relationship between custom and action against the background of Amedeo Giovanni Conte’s nomotropism. Starting with Frerichs’ provocation of the peculiarity of saying ‘handeln nach der Sitte’ (acting according to custom) in favor of ‘sich handelnd nach was üblich ist’ (acting after what is usual), this paper will begin an exploratory research regarding the semantics and the ontology of custom to investigate the possibility of a nomotropic behavior in the field of custom. Therefore, this paper will quote, at first, Rudolf von Jhering’s theory, and, at second, Ferdinand Tönnies’ theory. In conclusion, this paper suggests that an inquiry into custom in action (and in particular Tönnies’ ontology of the normative) could benefit from the nomotropic categories of analysis – such as adeontic and deontic regularities.

Active and reactive power flow regulation for a grid connected vsc based on fuzzy controllers
Authors: Díaz Aldana Nelson , Trujillo César Leonardo , Guarnizo José Guillermo
Published: November 2023

Voltage Source Converters (VSC) are one of the most used converters in distributed generation application and HVDC systems, since a VSC can operate either as inverter or rectifier. Furthermore, a VSC allows fast, accurate and independent active and reactive power flow control. However, a VSC is a double- input double-output non-linear control objet, therefore; nonlinear control strategies can be useful in order to obtain desired behaviors. In particular, knowledge based fuzzy controller does not require a mathematic model of the system it just relies on a qualitative knowledge about the behavior of the system. Moreover, the same fuzzy controller can be applied to any VSC with any power ratio. This paper presents the analysis, design and results obtained by using fuzzy controllers for regulating the active and reactive power flow in a Voltage Source Converter (VSC) connected to the utility grid. Additionally, it is shown that the transitory and stationary response of the VSC depends on the shape of membership functions at different power ratios. Digital simulation was performed in order to verify the behavior of the controller under different power levels. Finally, a VSC prototype with fuzzy controllers was tested experimentally.

Authors: Ramírez Patiño Juan Fernando , Isaza Jésica Andrea , Mariaka Isabela , Vélez Zea Jaime Andrés
Published: November 2023

A comparison between the healthy bone and the amputated bone of twenty unilateral transfemoral amputees was done by generating three Hounsfiled Unit (HU) histograms at different parts of the femur (femoral head neck, metaphysis and diaphysis), based on images obtained by Computer Axial Tomography. The results show a significant statistical difference (p-value<0.05) of HU, which is reflected by the bone mineral density between the bones of amputated and healthy limb. These differences demonstrate that the exoprosthesis use, generates bone demineralization which is also related with stress shielding phenomenon.

Authors:   University of Toronto, Cherki El Idrissi Sarah , Corbett Jacqueline ,   Université Laval, Mellouli Sehl ,   Université Laval
Published: November 2023

While information systems organizations recognize the importance of incorporating responsible innovation into their activities, they often face difficulty implementing this practice because employees lack the required knowledge and skills, particularly the capacity for reflexivity and reflection. This paper aims to accelerate responsible innovation teaching and training for information systems students to expedite the process of positive change for sustainability. Using the action design research methodology and the responsible innovation lens, we developed a workshop enabling information systems students to form measurable reflection skills. The workshop evaluation suggests that learning took place and that students are willing to adopt responsible innovation in their future workplaces. A set of design guidelines is proposed to guide further training programs to enhance students’ ability to address complex challenges responsibly. This paper answers the call for more impactful information systems research to address societal and environmental challenges and enriches the literature on sustainable social development and business practices.

The Expectation Disconfirmation Theory of Green Banking Practices of State Bank of India with special reference to Kerala - A Structural Equation Modeling Approach
Authors: S. Girish , A. P. Prasanth
Published: November 2023

In light of Agenda 2030, sustainability awareness is steadily growing worldwide. All institutions, including banks and financial institutions, are working to reduce their carbon footprints. Several indirect problems have arisen for India as a result of the banking process, such as global warming, climate change, irregular monsoon, air pollution, heavy rain, poor air quality, health problems, ozone depletion, fossil fuel use, recurrent destruction of forests for daily use, improper e-waste disposal. These issues can be overcome with sustainable banking practices (Green banking), which benefit the customer's satisfaction and quality of life. However, sustainability can be achieved only when the customers accept green banking and are satisfied with it. In order to do that, the bank must understand the level of expectations and perception of its customers toward green initiatives and to what extent the initiatives satisfy their day-to-day needs. This paper provides an overview of Expectancy disconfirmation integrations into customer satisfaction of India's largest public sector banks. As part of the present theoretical analysis, we first examine the level of awareness, expectations, and perception differences of customers to determine their satisfaction level. We then provide some evidence from SBI in Kerala regarding dissatisfying factors in green banking practices.

Also, in the context of emerging economies, this study will add to the expanding body of literature on sustainability and consumer behaviour.
Seasonality of California Central Coast Microseisms
Authors: Shabtian Hannah S. , Eilon Zachary C. , Tanimoto Toshiro
Published: November 2023

Linear scattering of ocean wave energy at the ocean–continent transition structure causes the primary microseism at a period of 14 s. Subsequent nonlinear wave–wave interactions produce the secondary microseism signal at half the primary microseism period (Longuet-Higgins, 1950; Haubrich et al., 1963). We use three years (2018–2022) of seismic data from an ongoing microarray deployment in the UC Santa Barbara Sedgwick Reserve, situated in the Santa Ynez Valley, to constrain seasonal and long-term microseismic noise characteristics for this portion of California’s central coast. Ancillary buoy data (spectral data, wave height, wind speed and direction) from the National Oceanic and Atmospheric Administration are used to explore the causal relationship between ocean swell and the generation of microseisms. This region is found to exhibit strong seasonality in the primary and secondary microseism bands (0.05–0.1 and 0.1–0.3 Hz, respectively), with much higher noise levels in the winter compared with the summer, especially for the secondary microseism (15.4 dB). We also observe a systematic shift in the peak frequency of the secondary microseism between the winter (∼0.14 Hz) and summer (∼0.20 Hz) months, which may reflect a difference in sources of secondary microseisms between the two seasons. Local buoy wave height and spectral data are well correlated with seismic power spectra during times of incoming storm swell in winter, indicating locally generated microseisms along the central coast during this season.

Published: November 2023

Archival earthquake studies often focus on event and source characteristics for use in earthquake catalogs, seismotectonic understanding, and ground-motion studies—many of these targeting better constraints for probabilistic seismic-hazard analyses. The ShakeMap Atlas, in contrast, focuses on spatial distribution of shaking for the historical events, providing the best constraints at all locations that experienced significant shaking for each event, facilitating analyses of human experience, damage, and induced hazards (ground failure). The aim of the Atlas is to gain a general understanding and depiction of the shaking distribution for a suite of canonical earthquakes, and, coupled with loss data for each event, to provide a basis for earthquake loss model calibration, among other uses. Although the initial motivation for developing the ShakeMap Atlas was calibrating the U.S. Geological Survey (USGS) Prompt Assessment of Global Earthquakes for Response system, over time, the Atlas has proved to be a useful tool for its users, and, as such, its scope has been vastly expanded in this newest version. The fourth version of the USGS ShakeMap Atlas is an openly available compilation of over 14,000 ShakeMaps of significant global earthquakes between 1900 and 2020. This revision includes: (1) the latest version of the ShakeMap software that provides refined uncertainty estimations and improved methods to combine macroseismic observations with updated ground-motion models; (2) an updated earthquake source catalog; (3) a refined strategy to select suites of prediction and conversion equations based on a new seismotectonic regionalization scheme; and (4) expanded macroseismic intensity and ground-motion datasets. We also tabulate reported economic losses and fatalities for Atlas events where such data are openly available. These changes make the new ShakeMap Atlas a self-consistent, calibrated catalog invaluable for investigating near-source ground motions, as well as seismic hazard, scenario, risk, and loss-model development and testing.

In terms of the treatment of depression, it is proven by many research that antidepressant drug has a significant impact on the treatment of depression patients. They can make them feel better and cope with their challenges. However, discontinuing these medications can be challenging due to concerns such as relapse, withdrawal symptoms, recurrence, and patient preferences. In this paper, we conducted a review of research on strategies for stopping antidepressants. Explored their long-term effects. By analyzing randomized controlled trials, cohort studies, systematic reviews, and meta-analyses, we gained insights into discontinuation methods and the extended impact of antidepressant use. Findings from quality evidence suggest that abruptly stopping antidepressants increases the risk of relapse or recurrence compared to reducing dosage or continuing with medication. Similarly, reducing dosage gradually helps in decreasing the risk and severity of withdrawal symptoms when compared to discontinuation or continued use without tapering off. Furthermore, psychological interventions like therapy or mindfulness-based cognitive therapy are identified as a best protocol for preventing relapse or recurrence after discontinuing antidepressants. These interventions are found to be particularly effective for patients experiencing symptoms or having risk factors. Additionally, although there is evidence regarding the long-term outcomes of using antidepressants beyond two years, some studies suggest that additional interventions such as patient education, shared decision-making processes monitoring progress, and providing feedback can assist in supporting successful discontinuation by improving adherence and patient satisfaction. In summary, stopping antidepressant medication is a process that necessitates assessment.

Diabetes mellitus, a global health crisis, necessitates effective prevention strategies. The prevalence of diabetes is on a relentless rise, leading to severe complications and imposing a substantial societal burden. Diabetes prevention has taken center stage in the public health arena. The imperative to develop effective strategies for preventing diabetes, particularly type 2 diabetes, has never been more apparent. The primary goal of diabetes screening is to identify individuals at risk of developing the disease, particularly type 2 diabetes. This paper explores the multifaceted landscape of diabetes prevention, emphasizing the role of lifestyle modifications, screening, and risk reduction. Lifestyle modifications encompass dietary changes, physical activity, and behavioral adjustments, forming the foundational approach. Screening, with various methods and risk assessment tools, identifies at-risk individuals, allowing for timely interventions. Risk reduction strategies target modifiable factors and are essential for both preventing diabetes onset and mitigating complications. These approaches empower individuals, healthcare professionals, and policymakers to combat diabetes's increasing prevalence and its associated health and economic consequences.

A Economia Circular (EC), surge em meados da década de 1970 como um sistema regenerativo e restaurador, contrariamente ao sistema linear, os princípios da EC prezam pela circularidade constante de materiais e componentes na economia, defendendo o aproveitamento máximo do seu valor. Nesse contexto, este trabalho tem como objetivo geral discutir teoricamente as Compras Públicas Circulares (CPC) como indutoras do processo transitório para uma economia circular, tendo como desdobramento os objetivos específicos de analisar as características complexas compartilhadas entre Compras Públicas Sustentáveis (CPS) e CPC e identificar quais critérios técnicos das CPS celebradas pela administração pública brasileira são orientados à circularidade. Para isso, adota uma metodologia qualitativa, utilizando técnicas de pesquisa descritiva explicativa, coleta de dados, revisão bibliográfica e análise documental. A partir dela, foi possível identificar que CPS e EC complementam-se, introduzindo um novo conceito na discussão: as CPC, processo de compra realizado pela administração pública que incentiva a transição para uma economia sustentável, com novos padrões de consumo e produção. A partir da adoção de critérios sustentáveis no processo licitatório, a administração pública, além de reguladora e normatizadora, torna-se agente direto da mudança, refletindo em alterações do mercado e incentivando empresas a inovarem seus processos para se adequarem às novas demandas sustentáveis.

Published: November 2023

Routine diagnosis of pulmonary disorders in bovines by physical examination, hematology and radiography is not sufficient to establish confirmatory diagnosis. Tracheo-bronchial aspirates (TBA) can be used as a reliable sample for the diagnosis of lower respiratory tract affections in cattle. Percutaneous tracheo-bronchial aspirate sampling was performed in 173 standing conscious cattle using two types of catheters. Fifty four cows were sampled with Large Animal transtracheal wash Kit (MILA International, Inc. USA) and 119 with infant feeding tube. Cytologic analysis of TBA smears was performed to assess the diagnostic utility of samples. Diagnostic samples were obtained in 87.8 per cent cows (152/173). Sampling using commercial catheter and infant feeding tube retrieved diagnostic samples in 90.7 per cent and 86.6 per cent of cows, whereas repeated infusions were required in 61.2 per cent and 78.7 per cent of cases, respectively. None of the cows exhibited complications post sampling. Infant feeding tube (7 Fr) with 10 G steel introduction catheter was effectively used in the collection of TBA and was comparable with commercial catheter. Present communication reports first systematic study on collection of TBA by percutaneous method in adult pneumonic cattle.

Published: November 2023

Background and Purpose:Nursing student retention is essential to meet workforce demands. Jeffreys’ Nursing Student Retention Student Perception Appraisal-Revised (SPA-R1) has been used extensively to understand factors that impact retention. Psychometric testing of the SPA-R1 contributes to greater confidence in the instrument’s reliability and validity.Methods:Item response theory and specifically, the single parameter polytomous Rasch model was used as a framework for fit statistic testing and rating scale diagnostics of the SPA-R1. This was a secondary analysis of a convenience sample of undergraduate prelicensure nursing students. The setting for the previous study was virtual, and the study period was 2022.Results:The model item characteristic curves for the 27 items of the SPA-R1 have similar shapes and are clustered in proximity. Overall, there are three clusters of items evident in the Rasch standardized residual contrast. The Rasch scale diagnostics indicated that the scale appropriately monotonically increases. However, there is a greater than 5 logit distance between does not apply and severely restricts, between severely restricts and moderately restricts, and between does not restrict or support and moderately supports. These large threshold distances indicate that additional steps in the scale may be warranted. The items cover the mid-range of the amount of retention perceptions; however, there are no items that represent the highest magnitude of the perceived amount of influence on retention.Conclusions:This study contributes further evidence to support the validity and reliability of the SPA-R1. We recommend adding steps to the scale, removing the does not apply response option, and considering scoring by three domains or clusters.

Published: November 2023

Introduction: Companies generally apply a shift system to keep production running. Implementing work shifts is not necessarily independent of the risks, especially for workers who carry it out. Aims: to analyze the impact felt by operator workers from the implementation of the shift work system that is currently being undertaken, in terms of its impact on physiological, performance, psychological, and social aspects. Method: This research used a qualitative approach. The research was conducted at the powerhouse and the informants in this study were management and employees of the powerhouse operator. Collecting the required data was done by interviewing and observation techniques. Meanwhile, the discussion used descriptive method. Result: The results showed that the backward shift pattern applied by the company did not have a break. It is known that there are several impacts felt by workers as a result of implementing backward work shifts, such as disturbed sleep patterns, experiencing digestive disorders such as bloating and diarrhea, feeling excessively depressed, and workers experiencing social interaction barriers outside of work. However, the shift pattern currently applied has no impact on the performance of the operator. Conclusion: The shift pattern implemented has an impact on operator workers, especially on physiological, psychological and social aspects. Therefore, there is still a need for improvement in the shift pattern applied.

Tau accumulates in Alzheimer’s disease (AD), frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP-17), chronic traumatic encephalopathy (CTE), progressive supranuclear palsy, and related tauopathies. Knowledge of the mechanisms for tau propagation in neurodegeneration is necessary for understanding the development of dementia. Exosomes, known as extracellular vesicles (EVs), have emerged as participants in promoting tau propagation. Recent findings show that EVs generated by neurons expressing familial mutations of tauopathies of FTDP-17 (P301L and V337M) (mTau) and presenilin (A246E) (mPS1) in AD induce tau propagation and accumulation after injection into rodent brain. To gain knowledge of the proteome cargoes of the mTau and mPS1 EVs that promote tau pathogenesis, this review compares the proteomes of these EVs, which results in important new questions concerning EV mechanisms of tau pathogenesis. Proteomics data show that EVs produced by mTau- and mPS1-expressing iPSC neurons share proteins involved in exocytosis and vesicle secretion and, notably, these EVs also possess differences in protein components of vesicle-mediated transport, extracellular functions, and cell adhesion. It will be important for future studies to gain an understanding of the breadth of familial genetic mutations of tau, presenilin, and other genes in promoting EV initiation of tau propagation and pathogenesis. Furthermore, elucidation of EV cargo components that mediate tau propagation will have potential as biomarkers and therapeutic strategies to ameliorate dementia of tauopathies.

The exploration of efficient electrocatalysts for carbon dioxide reduction reaction (CO2RR) with viable activity and superior selectivity remains a great challenge. The efficiency of CO2RR over traditional transition metal-based catalysts is restricted by their inherent scaling relationships, so breaking this scaling relationship is the key to improving the catalytic performance. In this work, inspired by the recent experimental progress in the synthesis of dual atom catalysts (DACs), we reported a rational design of novel DACs with two transition metal atoms embedded in defective MoS2 with S vacancies for CO2 reduction; 21 metal dimer systems were selected, including six homonuclear catalysts (MoS2-M2, M = Cu, Fe, Ni, Mn, Cr, Co) and 15 heteronuclear catalysts (MoS2-M1M2). First-principles calculations showed that the MoS2-NiCr system not only breaks the linear relationship of key intermediates but also possesses a low overpotential of 0.58 V and superior selectivity in the process of methane generation, which can be used as a promising catalyst for methane formation from CO2 electroreduction. Notably, by combining random forest regression machine learning study, we found that the CO2RR activity of DACs is essentially controlled by some fundamental factors, such as the distance between metal centers and the number of outer electrons in the metal atoms. Our findings provide profound insights for the design of efficient DACs for CO2RR.

In this paper, an analysis of the potential of using RES for the heat supply needs of public and residential buildings in Ukraine and the world is carried out. It was determined that Ukraine has one of the largest potentials in Europe for the use of RES. An analysis of the "Energy Strategy of Ukraine for the period until 2035 "Security, energy efficiency, competitiveness" was carried out and it was concluded that there is a trend towards decentralization of energy supply and an increase in the use of RES technologies for thermal energy generation. The total primary energy supply was analyzed by types of sources and volumes of generation. On the basis of a comparative analysis of actual and projected data on RES energy generation, it was concluded that there is a trend towards a gradual decrease in thermal energy generation by coal, gas, and oil-fired boilers, and an increase in generation using biomass boilers, solar collectors, and heat pumps. Based on the analysis of the Net Zero strategy, it was concluded that Ukraine and the world will gradually reduce the use of traditional generation and introduce modern technologies not only for the needs of electricity supply, but also for the needs of heat supply.

The modern stage of industrial development is characterized by an increasing need for systems to monitor the condition and efficient functioning of electrical equipment. Breakdown or unplanned stoppage of an electromechanical system engine is accompanied by significant economic losses for enterprises. Therefore, the current stage of industrial development is characterized by an increasing need for systems for monitoring the condition and efficient functioning of electrical equipment.

As a result, due to the rapid development of precision manufacturing technologies, many studies have been conducted in the field of multi-sensor measurement and data fusion technologies to improve monitoring capabilities in terms of measurement accuracy and information richness, thereby increasing production efficiency and accuracy. In a multi-sensor system, each sensor independently measures certain parameters. The system then uses an appropriate signal processing algorithm to combine all the independent measurements into a complete set of measurement results.

An accurate assessment of the technical condition makes it possible to predict the term of the next repair of the equipment, increases the reliability and efficiency of its operation, reduces the damage from downtime of the equipment due to accidents, the costs of repair and restoration of operability, reduces the costs of maintenance and operation of the equipment.

This article presents an overview of an intelligent multi-sensor system for monitoring the process and technological state of electrical equipment. Which in real time with the help of sensors makes it possible to obtain information from the environment and draw conclusions about the condition of the diagnosed equipment. The technology of an intelligent multi-sensor system for identification and assessment of the technical condition of electrical equipment has prospects for wide application in industries. Thanks to the most compact dimensions of the installation, we have the opportunity to take measurements in hard-to-reach places, without removing the equipment from work, which minimizes losses from downtime. Also, the use of this system allows detecting the development of a defect in the early stages of development, which prevents and significantly reduces the cost of repairing power equipment when it is out of service.
IDENTIFICATION AND CLASSIFICATION OF SINGLE-PHASE VOLTAGE DIPS USING THE METHODOLOGY OF THE SPATIAL VECTOR OF ANGULAR FREQUENCY

Published: November 2023

A new method of identification and classification of voltage dips in a three-phase electric network is presented. The method is based on the representation of voltages of the electrical network by one complex variable - a spatial vector of the angular frequency. The main characteristics of the spatial vector, which are used to identify and classify dips, are the major and minor semi-axes, the angle of rotation of the formed ellipse. For balanced dips, the space vector goes in a circle in the complex plane with a radius equal to the voltage. For unbalanced dips, the spatial vector is an ellipse with parameters that depend on the phase of the voltage drop, the magnitude of the dip, and the phase angle shift.

This method introduces a new level of accuracy and reliability in the analysis and classification of voltage dips, making it a tool for improving the quality of power supply and increasing the stability of electrical systems. The use of this method can help reduce the impact of unplanned interruptions in the supply of electricity to the enterprise and home, which is becoming a key task in the modern electricity sector.

This research presents a comprehensive computational analysis of the two-phase flow dynamics within a three-dimensional porous transport layer (PTL) in a proton exchange membrane (PEM) electrolyzer. Employing advanced computational fluid dynamics (CFD) and a volume of fluid (VOF) approach, the study utilizes the finite-volume method to model a time-dependent, isothermal process within a laminar flow regime. Notably, the study treats oxygen as the dispersed phase and water as the continuous phase within the system. Investigations on the anode side uncovered the formation of gas bubbles on the electrode's surface subsequent to the electrochemical reaction. The simulation, spanning 5 seconds with 0.25-second intervals, highlights the critical role of the time interval between the initiation and 2 seconds in achieving pressure and velocity equilibrium within the PTL. The initial 0.75 seconds witnessed a peak in oxygen concentration, followed by its movement across the PTL, exhibiting a transition from regions of lower to higher concentration, consistent with known physical behaviour. Remarkably, the model recorded the highest pressure of 3.5 Pa at 0.25 s. Furthermore, the study observed an incremental pressure drop from 0.25 s to 0.5 s and 1 s, approximately amounting to 28.5% and 20%, respectively, ultimately leading to a uniform pressure distribution within the model. Over time, the pressure drop intensified across the entire model due to the evolving nature of the oxygen gas. These findings provide valuable insights into the complex dynamics of two-phase flow processes within PEM electrolyzers, contributing to the advancement of sustainable energy technologies.
