A New Modeling Approach and Comprehensive Monitoring of Electrical Faults Through Spectral Analysis in DSIM

The objective of this study is to evaluate the dependability of double-star induction machines by employing meticulous monitoring and intelligent handling of potential electrical malfunctions that may arise during their functioning. Specifically, the research delves into the examination of three distinct fault types: rotor bar breakage, stator phase opening, and inter-turn short circuit. Utilizing a mathematical model developed in the natural reference frame (abc), our aim is to comprehensively delineate both normal and faulty operational scenarios. To categorize and gauge the gravity of identified faults, we employ a methodology rooted in spectral analysis. In order to ensure continuous machine operation, especially in instances of stator phase opening, our proposed mitigation approach entails intentionally opening a secondary phase positioned at a 90-degree angle to the faulty phase. This strategic alteration transforms the machine into a dual two-phase configuration. Through rigorous simulation analyses, our findings underscore the efficacy and pragmatic viability of the devised fault detection technique, offering valuable insights into the domain of electrical machine reliability and fault management.

Comparison performance study of singly-fed and doubly-fed induction generators-based bond-graph wind turbines model

This paper consecrates to a comparative performance study of singly-fed and doubly-fed of induction generators thrusted by wind power turbine of similar generation capacity of 2.5 kW, and constant or variably wind speed. The singly-fed induction generator model could be represented using natural reference frame and doubly-fed induction generator model is described using a Park reference frame. Because of several physical domains existing in both induction generators like mechanical and electrical, modeling of generators is difficult, therefore the modeling based on physical methods takes a high credibility under these conditions. Among the procedures is Bond-graph method that models the systems based on law of mass conservation and/or law of energy conservation containing in the systems. Modeling the parts of both singly-fed and double-fed induction generators are based on Bond-graph method. We found that the impact of stator coil winding for on the current is in the form of changes of its value and steady state intervals; increasing the number of stator coil windings may also lead to increased stator current and the longer their steady state interval. Our study demonstrates also that doubly-fed induction generator possesses advantages compared to singly-fed induction generator, namely better current quality output and an adaptation to fluctuating wind speeds. The performance study is done in constant and variably wind speeds using simulated results of 20-Sim software.

Observation and differential cross section measurement of neutral current DIS events with an empty hemisphere in the Breit frame

The Breit frame provides a natural frame to analyze lepton–proton scattering events. In this reference frame, the parton model hard interactions between a quark and an exchanged boson defines the coordinate system such that the struck quark is back-scattered along the virtual photon momentum direction. In Quantum Chromodynamics (QCD), higher order perturbative or non-perturbative effects can change this picture drastically. As Bjorken-x decreases below one half, a rather peculiar event signature is predicted with increasing probability, where no radiation is present in one of the two Breit-frame hemispheres and all emissions are to be found in the other hemisphere.

We report on the first observation of the empty current hemisphere events in electron–proton collisions at the HERA collider using data recorded with the H1 detector at a center-of-mass energy of 319 GeV.

On the emergence of gravity in a framework of emergent quantum mechanics

In this work, we consider the emergent origin of gravity in the framework of Hamilton–Randers theory, a theoretical framework for emergent quantum mechanics. After presenting the essential ingredients of the theory, a derivation of the weak equivalence principle from the first principles of the theory follows. Then it is shown that the Newtonian model of gravity and certain modified gravity models are consistent with Hamilton–Randers theory. One of these models has strong formal resemblance with MOND, providing further ground to think that Hamilton–Randers theory could be a natural theoretical frame for realistic modified gravity models.

‘We will continue to fight for our lands … it is Mother Nature that we value’: Idle No More, the Rights of Nature social movement frame, and Anti-Capitalist Ecologist Discourse

ABSTRACT Organizing to oppose an omnibus budget bill threatening First Nations in Canada, the Idle No More (INM) movement is embedded in a legacy of Indigenous resistance to colonialism and environmental degradation. INM activists challenged Western nature perceptions to advocate for the protection of nature through the lens of First and Indigenous Peoples’ traditions and cultures. We build upon existing Indigenous Environmental Justice movement, framing, and Rights of Nature (RoN) literature to understand the role of the RoN social movement frame and Anti-Capitalist Ecologist Discourse as orienting frameworks for INM movement mobilization. We explore the emergence period of INM, analysing the first 6 months of posts and comments on the movement’s Facebook page. We argue that INM activists employed an RoN frame to establish central claims and appeal to a range of potential supporters connecting the local and the global through broad Anti-Capitalist Ecologist Discourse narratives.

Classification and architectural planning components of riverine areas in the city structure

The study is devoted to the interaction of riverine areas with the urban structure. The purpose of the study is to provide substantiation for the classification of riverine territories in the city structure and to establish the architectural and planning components of riverine areas. The authors analyze global experience in the organization of riverine territories as part of urban development in the context of modern sustainable development programs. The results suggest that amid the increasing density of cities, changes in production interests, and climate change, there are trends in the regeneration of riverine areas. The study highlights the following trends in urban development: the creation of a system of recreational zones along the banks; creation of a network of city parks with different themes; incorporation of a spatial carcass into the structure; creation of public recreation centers, leisure complexes, and parking ensembles at the intersection of the urban and natural frames; rehabilitation and improvement of industrial areas; relocation of industrial plants situated among residential buildings to industrial areas; optimization of traffic and rational positioning of storage and maintenance facilities; development and organization of water protection zones and coastal protection strips. The conducted analysis of world experience confirms the need to find techniques to rehabilitate territories that are no longer effective while prioritizing the formation of a comfortable urban environment as a factor in raising their environmental and social efficiency.

Framing the wild: A qualitative analysis of environmental news coverage during the 2020 coronavirus lockdowns

News media coverage of the natural world frames perceptions and policies related to the environment. Studying its reporting brings insight for how meaning is assigned to humanity’s relationship with nature and wildlife. Through qualitative content analysis, this study examines digital articles on the environment, published from March to December 2020, amidst mass lockdowns due to the 2019 coronavirus (COVID-19) pandemic. Claims about the impact of humanity being locked down were analysed using framing theory. Findings revealed four major frames generated in connection to (1) wildlife behaviour, (2) a new normal post-COVID, (3) climate change being displaced and (4) human–nature symbiosis. The results of qualitative inquiry offer a more nuanced understanding of how media frames the complex human–nature relationship, which tends to feature negative and hostile associations. This furthers the notion that such framing can limit perspectives, even if unintended, and arguably weakens viewing our relationship with nature as symbiotic.

Quality balanced scorecard for the outpatient clinic

The quality audit system for healthcare in various countries is based on the quality of medical services, the satisfaction of the patient and his relatives, as well as the quality of medical documentation. At the same time, quality indicators of healthcare facilities include criteria of the social and economic efficiency. Often these groups of indicators are considered by researchers separately from each other, and the literature available does not show balanced approaches to combining indicators from different groups within one process, which served as the basis for this work.Aim. The article is devoted to identifying the specifics of quality balanced scorecard for outpatient clinic using the example of the results of preventive examination for children in the first year of life.Material and methods. The study of quality indicators of the outpatient clinic was carried out from 2019 to 2023. The base of the study was the Clinical Consultative and Diagnostic Clinic № 27 in Novosibirsk. The study of the Clinic development was carried out from 2012 to 2023. The work used data from a social and expert survey of managers (20122018), as well as comparative modeling, general logical methods and techniques.Results. The longest multi-level and complex medical service is the process of preventive examination of children in the first year of life. Therefore, using his example, a quality balanced scorecard for the outpatient clinic was developed. At the first stage, medical quality criteria were determined. Patients were interviewed and quality criteria important for the patients' parents were determined. The complexity, multi-stage nature and short time frame for providing medical services determined the criteria for the economic efficiency. At the second stage, criteria for the management effectiveness and criteria for quality monitoring were developed, which allow department heads to track key performance indicators, as well as build coordinated work between various departments. At the third stage, the quality criteria were developed, which, on the one hand, reflect the clinic work, and, on the other hand, are not redundant and can be used to assess the effectiveness of the organization as a whole.Conclusion. The study showed that to increase the sustainability of the clinic development, effective monitoring based on key performance indicators is necessary. The classical approach to determining the effectiveness of medical facilities is based on general performance indicators to the quality criteria of individual processes, which does not allow identifying violations in individual medical and auxiliary processes, and, accordingly, does not allow identifying ways to solve them. It also does not indicate the level of violation. The use of a process and system approach in developing quality criteria allows developing a quality balanced scorecard with respect to the criteria of various groups, which ultimately reflects the effectiveness of processes as a whole, provides an understanding of cause-and-effect relationships and identifies the root cause of destabilization.

A functional contextual, observer-centric, quantum mechanical, and neuro-symbolic approach to solving the alignment problem of artificial general intelligence: safe AI through intersecting computational psychological neuroscience and LLM architecture for emergent theory of mind.

There have been impressive advancements in the field of natural language processing (NLP) in recent years, largely driven by innovations in the development of transformer-based large language models (LLM) that utilize "attention." This approach employs masked self-attention to establish (via similarly) different positions of tokens (words) within an inputted sequence of tokens to compute the most appropriate response based on its training corpus. However, there is speculation as to whether this approach alone can be scaled up to develop emergent artificial general intelligence (AGI), and whether it can address the alignment of AGI values with human values (called the alignment problem). Some researchers exploring the alignment problem highlight three aspects that AGI (or AI) requires to help resolve this problem: (1) an interpretable values specification; (2) a utility function; and (3) a dynamic contextual account of behavior. Here, a neurosymbolic model is proposed to help resolve these issues of human value alignment in AI, which expands on the transformer-based model for NLP to incorporate symbolic reasoning that may allow AGI to incorporate perspective-taking reasoning (i.e., resolving the need for a dynamic contextual account of behavior through deictics) as defined by a multilevel evolutionary and neurobiological framework into a functional contextual post-Skinnerian model of human language called "Neurobiological and Natural Selection Relational Frame Theory" (N-Frame). It is argued that this approach may also help establish a comprehensible value scheme, a utility function by expanding the expected utility equation of behavioral economics to consider functional contextualism, and even an observer (or witness) centric model for consciousness. Evolution theory, subjective quantum mechanics, and neuroscience are further aimed to help explain consciousness, and possible implementation within an LLM through correspondence to an interface as suggested by N-Frame. This argument is supported by the computational level of hypergraphs, relational density clusters, a conscious quantum level defined by QBism, and real-world applied level (human user feedback). It is argued that this approach could enable AI to achieve consciousness and develop deictic perspective-taking abilities, thereby attaining human-level self-awareness, empathy, and compassion toward others. Importantly, this consciousness hypothesis can be directly tested with a significance of approximately 5-sigma significance (with a 1 in 3.5 million probability that any identified AI-conscious observations in the form of a collapsed wave form are due to chance factors) through double-slit intent-type experimentation and visualization procedures for derived perspective-taking relational frames. Ultimately, this could provide a solution to the alignment problem and contribute to the emergence of a theory of mind (ToM) within AI.

Fishy windows to an Arctic city: Urban (in)visibilities of global fisheries in Tromsø

Abstract Although “urban” and “fisheries” are not commonly paired in the analyses of either urbanism or fisheries governance, today’s large-scale fisheries are often closely organised in connection with cities. In this paper, I build on a feminist perspective and urban studies to examine the makings of a city through contemporary fisheries. Drawing upon observations and interviews conducted in Tromsø, Norway, which is a key site for Arctic fisheries, I review how fish and fisheries are simultaneously made visible and invisible in urban spheres. By analysing the gendered structures and valuations that organise the city–fisheries relations, I introduce three “fishy” windows to demonstrate the kinds of development and future pathways for fisheries that are considered relevant and rational in and for the city. In particular, I discuss how the historical, techno-masculine narratives of mastering Arctic nature frame and legitimise fisheries practices as they expand throughout Tromsø. The study builds on the emerging research on Arctic urbanism to highlight the need to better integrate gendered analyses of the “urban” into social science research on natural resource extraction.

Parametric Design and Genetic Algorithm Optimization of a Natural Light Stereoscopic Cultivation Frame

Vertical farming (VF) is an emerging cultivation frame that maximizes total plant production. However, the high energy-consuming artificial light sources for plants growing in the lower and middle layers significantly affect the sustainability of the current VF systems. To address the challenges of supplementary lighting energy consumption, this study explored and optimized the structural design of cultivation frames in VF using parametric modeling, a light simulation platform, and a genetic algorithm. The optimal structure was stereoscopic, including four groups of cultivation trough units in the lower layer, two groups in the middle layer, and one group in the upper layer, with a layer height of 685 mm and a spacing of 350 mm between the cultivation trough units. A field experiment demonstrated lettuce in the middle and lower layers yielded 82.9% to 92.6% in the upper layer. The proposed natural light stereoscopic cultivation frame (NLSCF) for VF was demonstrated to be feasible through simulations and on-site lettuce cultivation experiments without supplementary lighting. These findings confirmed that the NLSCF could effectively reduce the energy consumption of supplemental lighting with the ensure of lettuce’s regular growth. Moreover, the designing processes of the cultivation frame may elucidate further research on the enhancement of the sustainability and efficiency of VF systems.

Sources of Motivation: Theorists and their Theories

Motivation describes the reasons individuals behave as they do. Motivation psychologists’ have studied the individuals’ behavior (e.g., ability, strength, persistence) as well as their cognitions and emotional responses that affect them. Some researchers periodically mistake motivation with learning. Many psychologists attempted to recognize the individuals’ instincts or natural frame of mind that guides their behavior. First Maslow’s hierarchy of needs and motivation theories, their theorists, and contributions are discussed. Next motivation theorists are compared. Then there is a discussion of contemporary approaches to motivation that in part have been based on the heritage of the outstanding theories that have are partially addressed. Finally, it closes with a reflection on the future of motivational research.

The landslide's conceptualizing economic decline and its framing effect: Mandarin evidence.

Conceptual metaphors are essential for explaining and understanding social concerns. Natural disaster metaphors are commonly employed to access the abstract and negative impacts of social issues. Five of the top 10 most prevalent natural disaster frames in the Center for Chinese Linguistics (CCL)-earthquake, flood, fire hazard, drought, typhoon, landslide, volcano, sandstorm, tsunami, and debris flow-share a common economic target domain and show economic recession. Additionally, corpus-based research has revealed that the landslide frame is the most salient in figuratively representing economic declines. An experimental study derived from the corpus analysis has found that the landslide-framed economic crises posed more severity to participants and exerted a notable influence on their opinions and judgments. Therefore, when effective communication of economic hazards is to be realized, metaphorical representation of economic crises demands great consideration.

Angular Velocity Control of Three-Phase PMSM Using Only Stator Currents and Angular Position

A strategy of angular velocity control of the three-phase permanent magnet synchronous motor is presented in its natural reference frame, i.e., no transformations are made to the mathematical model, so the design of the control algorithm is carried out with the three differential equations obtained for the stator windings as well as with the electromagnetic torque that results with the three stator currents, with the assumption that only the signals of both the stator currents and the angular position are available. To obtain a signal that relates to angular velocity, a state-space representation of a second-order linear filter is used. Likewise, a formal stability analysis of the entire system is presented.

Computational assessment of visual coding across mouse brain areas and behavioural states.

Our brain is bombarded by a diverse range of visual stimuli, which are converted into corresponding neuronal responses and processed throughout the visual system. The neural activity patterns that result from these external stimuli vary depending on the object or scene being observed, but they also change as a result of internal or behavioural states. This raises the question of to what extent it is possible to predict the presented visual stimuli from neural activity across behavioural states, and how this varies in different brain regions. To address this question, we assessed the computational capacity of decoders to extract visual information in awake behaving mice, by analysing publicly available standardised datasets from the Allen Brain Institute. We evaluated how natural movie frames can be distinguished based on the activity of units recorded in distinct brain regions and under different behavioural states. This analysis revealed the spectrum of visual information present in different brain regions in response to binary and multiclass classification tasks. Visual cortical areas showed highest classification accuracies, followed by thalamic and midbrain regions, with hippocampal regions showing close to chance accuracy. In addition, we found that behavioural variability led to a decrease in decoding accuracy, whereby large behavioural changes between train and test sessions reduced the classification performance of the decoders. A generalised linear model analysis suggested that this deterioration in classification might be due to an independent modulation of neural activity by stimulus and behaviour. Finally, we reconstructed the natural movie frames from optimal linear classifiers, and observed a strong similarity between reconstructed and actual movie frames. However, the similarity was significantly higher when the decoders were trained and tested on sessions with similar behavioural states. Our analysis provides a systematic assessment of visual coding in the mouse brain, and sheds light on the spectrum of visual information present across brain areas and behavioural states.

Natural hazard versus natural disaster: Does framing the event affect preparedness intentions, attitudes, and behaviour?

Even when perception of risks such as earthquakes is high, preparation is generally low. Previous research shows relatively minor changes in the framing of target issues can impact decisions. In the area of risk, the terms “natural hazards” and “natural disasters” are used inconsistently. Using the Theory of Planned Behaviour as a framework, we conducted an online experiment with a large community sample from Wellington, Aotearoa New Zealand (N = 604) to examine possible framing effects. Half of the participants were asked about their attitudes and intentions regarding preparing for natural hazards and half about natural disasters. We found few significant differences in mean factor scores between the two groups, suggesting that people have attitudes and perceptions of similar strength for both natural hazards and natural disasters. However, half of the factors in structural equation modelling differed in significance or valence between the two conditions and intentions to prepare were positively associated with information-seeking behaviour only for the natural hazards frame, not the natural disaster frame. These findings suggest that the way in which these issues are framed meaningfully impacts how intentions form and translate to actual behaviour. It is possible that participants understood disaster as manifested, devastating impacts of a natural event rather than the potential for impact implied by the term hazard. Such interpretations could influence perceptions of preventability, and therefore preparation. These findings have critical implications for public information campaigns and interventions aimed at increasing preparedness for the risk posed by natural hazards.

Methods for the quantification of uncertainties in thermo–hydro–mechanical simulations for safety analyses and influence of modelling decisions

Abstract. The simulation of thermal, hydraulic, and mechanical coupled processes can be a decisive factor in the integrity assessment of geotechnical and geological barriers. Modelling decisions, such as the representation of heterogeneity and the constitutive models used, significantly impact the simulation outcome (Wagener and Pianosi, 2019). Furthermore, numerical inputs to the simulation, i.e. material parameters and boundary conditions, are subject to uncertainty. This results in a lower confidence level of the outcome, even if the overall simulation framework is well validated. To derive robust conclusions from such analyses, it is important to quantify the relative impact of modelling decisions and inputs on certain quantities of interest. Parameter uncertainties can be quantified by their forward propagation through the discretized problem (Helton, 1994), providing a natural frame of reference for quantifying structural uncertainty (Bond et al., 2007), such as the representation of heterogeneity, and for model validation. This contribution will focus on the latter aspects. We present research on workflows for the unification of evaluating uncertainty in experimental data and certain modelling decisions. We first focus on parameter uncertainty quantification and the resulting conclusions concerning the chosen modelling approach. Hereafter, scale questions are addressed in the context of heterogeneity and anisotropy, based on selected case studies. We close by discussing two example applications, namely one at the Underground Research Laboratory (URL) scale (Mount Terri Full-Scale Emplacement (FE) experiment) and one at the repository scale (ANSICHT Ton Nord model). This work is done as part of the Bundesministerium für Umwelt, Naturschutz, nukleare Sicherheit und Verbraucherschutz (BGE URS) research cluster.

Design research for menopause: a scoping review

More than half the global population experience menopause, of which a significant number are in part-time or full-time employment. Research on labour force participation reports that employment is often interrupted during the menopausal transition due to difficulties accessing timely medical support and social discrimination. These interruptions result in the loss of professional expertise for employers and financial security for employees. To identify the characteristics of and gaps in design research for menopause we conducted a scoping review of the literature. We sourced and analysed 24 articles, mapping them according to their alignment with three conceptual framings of menopause from the sociology of medicine; a medicalized condition requiring pharmacological treatment, a natural life stage that is managed with complementary therapies, and a demedicalized issue where illness and health are framed as always socially situated. We found that the articles on menopause were relatively evenly distributed across the medicalized and demedicalized framings, with fewer developed within a natural framing. Our findings offer design researchers an overview of frameworks that are commonly used in health research and that we see as productive for further multidisciplinary research collaborations for menopause, and for research concerning the intersections of gender, sexualities, ageing and health more broadly.

Inductor-Volume Comparison for 3Φ3W LCL Converter With Direct Digital Control and Different Filter-Inductance Drop-Rates

Magnetic powder cores have soft-saturation properties and high temperature stability compared with other materials, which are widely used in LCL filter design. Conventionally, when designing a filter for a 3Φ3W LCL converter controlled with abc-to dq frame transformation, a low drop-rate inductor is selected to stabilize the system and improve the current THD; however, it results in high inductor volume. With the proposed direct digital control (DDC) operating in nature frame, the filter is allowed to have a wide inductance drop-rate (75%) which can reduce core size significantly. The DDC is first addressed and the filter design is correspondingly presented. Comparison of filter volume, loss, and temperature rise for the converters with DDC and different drop-rates is presented, and it is the primary contribution. Simulated and experimental results from a 33 kW 3Φ3W LCL converter with different inductance drop-rates have been used to verify the analyses and discussions.
