Effect of different injection fluids scenarios on swelling and migration of common clays in case of permeability variations: a micromodel study
Authors: Karami Mehran , Sedaee Behnam , Nakhaee Ali
Published: May 2023

Swelling and migration of present clays make damage to the oil reservoirs due to low salinity waterflooding (LSWF) can induce serious problems in the case of oil recovery improvement and researchers are trying to solve this problem. The purpose of this work is to investigate the mechanism of two phenomena of swelling and migration clays in the porous media of a reservoir rock by injecting a different composition of LSWF using a glass micromodel and providing the appropriate composition and pattern of injection with the removal of damage. Proper water flooding design, application of efficient swelling inhibitors, and migration control are among the most important methods to overcome the problem of formation damage due to swelling and migration of clays. A series of static (bulk or bottle test) and dynamic tests were carried out using a micromodel with a coating of kaolinite and montmorillonite clays in the vicinity and injection of different low salt water compositions. The type and amount of these clays were selected based on the results of XRD and SEM mineralogical tests on real reservoir rock, FW and diluted FW, SW and diluted SW, solution of 1% zirconium oxychloride in 20 times diluted seawater (SI), and composition of nanofluid MgO, SiO2, and Al2O3 in 20 times diluted. In the studies conducted by the micromodel, only the images taken were used in the analysis of the mechanisms, but here, the input and output pressures of the micromodel were recorded with high-precision pressure transmitters, and by using the differential pressure, the permeability was calculated and the formation damage index was introduced. The overlap of the interpretation of the captured images and the changes of the numerical parameter of the damage index in all stages of injection of smart water composition was considered to evaluate the simultaneous and separate mechanisms of swelling and migration of clays. The results of the experiments in this research show that clay swelling has destructive effects on permeability, and migration due to the transfer of clays from the porous medium can have promising effects on reducing the damage index in some conditions. And it is necessary to use the swelling control compound during the flooding process, but the migration inhibitor compound is not always suitable. Gradual reduction of salinity is also introduced as a pattern to prevent swelling damage or clay migration.

In general, in this study, the best design and fluid engineering for smart water injection with the least damage in the micromodel scale was presented.
The Representational Consequences of Electronic Voting Reform
Authors: Alles Santiago , Barnes Tiffany D. , Tchintian Carolina
Published: May 2023

Ballots and voting devices are fundamental tools in the electoral process. Despite their importance, scholars have paid little attention to the broader implications of voting procedures. In this Element, the authors contend that ballots have significant implications for democratic representation, as they affect the cost associated with voting for citizens and electioneering for elites. This Element explains how ballot designs affect the behavior of voters, the performance of candidates, and the strategies of parties. It shows how voting procedures structure the likelihood of vote splitting and ballot roll-off. This in turn has implications for candidates. Focusing on gender and experience, this Element shows how ballot form alters the salience of personal vote earning attributes. With respect to political parties, ballot structure can shift both the cost, strategies, and ultimately electoral fortunes of political parties. Finally, it discusses the profound implications ballot forms have for party campaigns and election outcomes.

Effective training practices for non-specialist providers to promote high-quality mental health intervention delivery: A narrative review with four case studies from Kenya, Ethiopia, and the United States
Authors: Barnett Miya L. , Puffer Eve S. , Ng Lauren C. , Jaguga Florence
Published: May 2023

Mental health needs and disparities are widespread and have been exacerbated by the COVID-19 pandemic, with the greatest burden being on marginalized individuals worldwide. The World Health Organization developed the Mental Health Gap Action Programme to address growing global mental health needs by promoting task sharing in the delivery of psychosocial and psychological interventions. However, little is known about the training needed for non-specialists to deliver these interventions with high levels of competence and fidelity. This article provides a brief conceptual overview of the evidence concerning the training of non-specialists carrying out task-sharing psychosocial and psychological interventions while utilizing illustrative case studies from Kenya, Ethiopia, and the United States to highlight findings from the literature. In this article, the authors discuss the importance of tailoring training to the skills and needs of the non-specialist providers and their roles in the delivery of an intervention. This narrative review with four case studies advocates for training that recognizes the expertise that non-specialist providers bring to intervention delivery, including how they promote culturally responsive care within their communities.
How relevant is the APA ethics code to industrial-organizational psychology? Applicability, deficiencies, and recommendations
Authors: Watts Logan L. , Lefkowitz Joel , Gonzalez Manuel F. , Nandi Sampoorna
Published: May 2023

Opinions have been divided regarding the relevance of the APA Ethics Code to non-mental health specialties and even whether the code should attempt to encompass all psychology specializations. However, these opinions have crystallized without the benefit of any appreciable empirical data, until now. This study investigates the applicability of the ethical principles and standards of the code to 398 first-person narratives of ethical incidents reported by industrial-organizational (I-O) psychologists. On average, 2.8 (of the 5) principles enumerated in the code were deemed applicable to each incident, and each principle was applicable to more than half the incidents provided. Of the code’s 89 ethical standards, 75 (84.3%) were applicable to at least one incident. Among the 10 categories of standards, resolving ethical issues and human relations were the most frequently applicable, whereas therapy standards were virtually never applicable. However, for 42.7% of the incidents, trained judges identified a substantive deficiency or ambiguity for I-O psychologists in the code. These deficiencies were subsequently grouped into seven higher order categories (assessments in organizations; research practices; data management; professional interactions; business practices; student ethics; and proactive ethical behavior). Recommendations are offered for improving those putative deficiencies, and implications are discussed for I-O psychologists, the APA’s Ethics Code Task Force (ECTF), and other nonclinical domains of psychology.
The potential of fostering connections: Insights into polycultural organizations
Authors: Valenzuela Marcus A. , Bernardo Allan B. I.
Published: May 2023

Diversity in organizations is a recurring and increasing reality of vast importance. The diversity management literature describes different types of organizations based on their treatment and management of diversity, including plural and multicultural organizations. However, recent research suggests the added value of considering polycultural organizations in diversity management. Based on a polycultural ideology that sees values, traditions, and norms inherently and dynamically intertwined and mixed, polycultural organizations emphasize the value for and “connectedness” to diversity among organizational members. Contributing to the diversity management literature, this paper conceptually describes and compares polycultural organizations with other types of organizations in the diversity management literature. It argues the potential benefit of including a polycultural ideology to current perspectives in diversity management to further advance our understanding of how diversity can be effectively managed in organizations. Additionally, practice implications and strategies to foster polycultural organizations are provided.
Transient behaviour of decelerating turbulent pipe flows
Authors: Guerrero Byron , Lambert Martin F. , Chin Rey C.
Published: May 2023

This investigation characterises the time response and the transient turbulence dynamics undergone by rapidly decelerating turbulent pipe flows. A series of direct numerical simulations of decelerating flows between two steady Reynolds numbers were conducted for this purpose. The statistical analyses reveal that rapidly decelerating turbulent flows undergo four coherent, unambiguous transitional stages: inertial (stage I), a dramatic change of sign in the viscous force associated with the decay of the viscous shear stress at the wall together with a mild turbulence decay in the viscous sublayer; friction recovery (stage II), a recovery in viscous force and progressive decay in the turbulent inertia at the near-wall region; turbulence decay (stage III), a balanced decay in both turbulent inertia and viscous force at the near-wall and overlap regions; core relaxation (stage IV), slow turbulence decay at the core region. The FIK identity derived by Fukagata, Iwamoto and Kasagi (Phys. Fluids, vol. 14, 2002, L73–L76) was used to understand further how the flow dynamics influence the time response of the skin friction coefficient (

$C_f$

). The results show that although

$C_f$

plateaus during the fourth stage, the turbulent contribution keeps decaying, undershoots and finally recovers to attain its final steady value. The time evolution of the azimuthal vorticity (

$\omega _\theta$

) flux reveals that as the flow is decelerated, a layer of negative

$\omega _\theta$

is produced at the wall during the flow excursion. As time progresses, this negative vorticity propagates in the wall-normal direction, attenuating the pre-existing vorticity and producing a decay in the turbulence levels.

Published: May 2023

Climate change has had a significant impact on glacier recession, particularly in the Arctic, where glacier meltwater is an important contributor to global sea-level rise. Therefore, it is important to accurately quantify glacier recession within this sensitive region, using multiple observations of glacier extent. In this study, we mapped 480 glaciers in Novaya Zemlya, Russian Arctic, using object-based image analysis applied to multispectral Landsat satellite imagery in Google Earth Engine and quantify the area changes between 1986–89 and 2019–21. The results show that in 1986–89, the total glacierized area was 22 990 ± 301 km2, in 2000–01 the area was 22 525 ± 308 km2 and by 2019–21 the glacier area reduced to 21 670 ± 292 km2, representing a total of 5.8% reduction in glacier area between 1986–89 and 2019–21. Higher glacier area loss was observed on the Barents Sea coast (7.3%) compared to the Kara (4.2%), reflecting previously observed differences in warming trends. The accuracy of the automatically generated outlines of each layer (1986–89, 2000–01 and 2019–21) was evaluated by comparing with manually corrected outlines (reference data) using random sampling, resulting in an overall accuracy estimate of between 96 and 97% compared to the reference data. This automated approach in Google Earth Engine is a promising tool for rapidly mapping glacier change that reduces the amount of time required to generate accurate glacier outlines.
Abolition, Community Control, and the Right to the City
Authors: Balto Simon
Published: May 2023

Some years ago, writing as the embers of the Great Recession still burned, Marxist geographer and social theorist David Harvey penned an essay in New Left Review titled “The Right to the City.” In it, Harvey, the primary exponent of French philosopher Henri Lefebvre's “right to the city” thesis (initially published as Le Droit à la ville in 1968), argued that “the right to the city is far more than the individual liberty to access urban resources: it is a right to change ourselves by changing the city.”1
Expansion of an Australian food composition database to estimate plant and animal intakes
Authors: Stanford Jordan , McMahon Sarah , Lambert Kelly , Charlton Karen E. , Stefoska-Needham Anita
Published: May 2023

Despite evidence for favourable health outcomes associated with plant-based diets, a database containing the plant and animal content of all foods eaten is required to undertake a reliable assessment of plant-based diets within a population. This study aimed to expand an existing Australian food database to include the plant and animal content of all whole foods, beverages, multi-ingredient products and mixed dishes. Twenty-three plant- and animal-based food group classifications were first defined. The food servings per 100 g of each product were then systematically calculated using either a recipe-based approach, a food label-based approach, estimates based on similar products or online recipes. Overall, 4687 (83·5 %) foods and beverages were identified as plant or plant-containing products, and 3701 (65·9 %) were animal or animal-containing products. Results highlighted the versatility of plant and animal ingredients as they were found in various foods across many food categories, including savoury and sweet foods, as well as discretionary and core foods. For example, over 97 % of animal fat-containing foods were found in major food groups outside the AUSNUT 2011–2013 ‘fats and oils’ group. Surprisingly, fruits, nuts and seeds were present in a greater percentage of discretionary products than in core foods and beverages. This article describes a systematic approach that is suitable for the development of other novel food databases. This database allows more accurate quantitative estimates of plant and animal intakes, which is significant for future epidemiological and clinical research aiming to investigate plant-based diets and their related health outcomes.

Published: May 2023

People with severe mental illness (SMI), including schizophrenia and related psychoses and bipolar disorder, are at greater risk for obesity compared with people without mental illness. An altered resting metabolic rate (RMR) may be a key driving factor; however, published studies have not been systematically reviewed. This systematic review and meta-analysis aimed to determine whether the RMR of people with SMI assessed by indirect calorimetry differs from (i) controls, (ii) predictive equations and (iii) after administration of antipsychotic medications. Five databases were searched from database inception to March 2022. Thirteen studies providing nineteen relevant datasets were included. Study quality was mixed (62 % considered low quality). In the primary analysis, RMR in people with SMI did not differ from matched controls (n 2, standardised mean difference (SMD) = 0·58, 95 % CI −1·01, 2·16, P = 0·48, I2 = 92 %). Most predictive equations overestimated RMR. The Mifflin–St. Jeor equation appeared to be most accurate (n 5, SMD = −0·29, 95 % CI −0·73, 0·14, P = 0·19, I2 = 85 %). There were no significant changes in RMR after antipsychotic administration (n 4, SMD = 0·17, 95 % CI −0·21, 0·55, P = 0·38, I2 = 0 %). There is little evidence to suggest there is a difference in RMR between people with SMI and people without when matched for age, sex, BMI and body mass, or that commencement of antipsychotic medication alters RMR.
Fighting Cyber Attacks with Sanctions: Digital Threats, Economic Responses
Authors: Rusinova Vera , Martynova Ekaterina
Published: May 2023

This article contributes to the understanding of why states resort to targeted, or smart, sanctions to meet the threat of cyber intrusions and whether this type of response is a forced measure or an effective tool to halt, prevent and punish attacking states. The tools of analysis used in the article are legal positivism and political theories, including Mancur Olson's theory of groups and Francesco Giumelli's analytical framework for assessment of sanctions. The authors address the effectiveness of sanctions as a reaction to cyber-enabled activities through the lens of regulation introduced in the United States, the European Union and the United Kingdom, which are the most developed counter-cyber sanction regimes, analysing publicly known cases of cyber-related sanctions.

Published: May 2023

The adverse effects that conservation can have on Indigenous Peoples and local communities have been known for decades. In recognition, governments and conservation organizations have adopted joint statements of intent and rolled out various individual measures to safeguard human rights. Nevertheless, a gap remains between policy and practice, as evidenced by numerous recent examples of human rights infringements because of the (in)actions of conservation. We present ethnographic research with people living adjacent to Pegunungan Cyclops, an IUCN category I(a) strict protected area in Papua Province, Indonesia, aiming to understand their experiences of conservation and provide some nuance regarding the gap between policy and practice in human rights and conservation. We uncovered feelings of injustice, discontent, confusion, an overall lack of consultation between local inhabitants and park managers and decades of contradictory policies and projects characterized by implementation problems stemming from scant resources. We also show how national struggles over rights and recognition are conflated and intertwined with local ones and how national and provincial policies can alter governance regimes, tenure arrangements and power relations locally. Despite the issues, our informants also recalled favourably instances in which partnerships between local inhabitants and other actors were well received because they were implemented through detailed consultation, producing management actions that better aligned with traditional practices. For people in the Cyclops Mountains today, the emerging avenues provided by the social forestry programme in Indonesia could be the most beneficial way to secure greater access to their lands, and conservationists can play a role in supporting this process.
Changes in a Neotropical insectivorous bat community associated with artificial clearing of the forest in a geothermal project

Published: May 2023

The energy needs of the human population inevitably affect natural environments, but the effects on wildlife of human modifications of habitat specifically for geothermal projects are scarcely known. Through acoustic monitoring, we quantified at Proyecto Geotérmico Las Pailas II, Guanacaste, Costa Rica, the impact of forest openings on the diversity and community composition of aerial insectivorous bats. Our data revealed that artificial clearing causes a border effect, an environment where the diversity of species and activity levels of insectivorous bats increase with respect to other habitats analysed. We discuss that, due to the combination of environmental properties and resource availability variables of the border habitats, in addition to the acoustic abilities of the bat species detected, borders represent transitional spaces where species adapted to uncluttered and background-cluttered spaces can easily commute and forage. The artificial clearings created by the geothermal project had a positive effect on aerial insectivorous bat species; however, this pattern cannot be assumed for other organisms within the area. Therefore, we highlight the importance of quantifying the influence of energy-extracting projects on biodiversity metrics and the use of this information to make informed decisions regarding managing and conserving natural resources.
“I can't see myself ever living any[w]ere else”: Variation in (HW) in Edinburgh English
Authors: Markl Nina
Published: May 2023

Sociolinguistic research across Scotland in recent decades has documented an erosion of the phonemic contrast between /ʍ/ (as inwhich) and /w/ (as inwitch). Based on acoustic phonetic analysis of 1,400  realizations produced by eighteen Edinburgh women born between 1938 and 1993, I argue that in the context of Edinburgh this is best understood as a complex sociolinguistic variable (HW) encompassing (at least) six fricated and fricationless variants. Realizations vary in type and relative duration of frication, voicing, and glide quality. Bayesian statistical analysis suggests that choice and realization of variants is conditioned by speaker's social class, style, and phonetic context. Unlike some prior work, I do not find evidence of ongoing (apparent-time) change or an effect of contact with Southern British English. Fricated variants are most prevalent in formal speech styles and in the speech of middle-class women, while working-class speakers favor fricationless variants.

Despite over a decade of both quantitative and qualitative studies, food insecurity among US college/university students remains a pervasive problem within higher education. The purpose of this perspective piece was to highlight research gaps in the area of college food insecurity and provide rationale for the research community to focus on these gaps going forward. A group of food insecurity researchers from a variety of higher education institutions across the United States identified five thematic areas of research gaps: screening and estimates of food insecurity; longitudinal changes in food insecurity; impact of food insecurity on broader health and academic outcomes; evaluation of impact, sustainability and cost effectiveness of existing programmes and initiatives; and state and federal policies and programmes. Within these thematic areas, nineteen specific research gaps were identified that have limited or no peer-reviewed, published research. These research gaps result in a limited understanding of the magnitude, severity and persistence of college food insecurity, the negative short- and long-term impacts of food insecurity on health, academic performance and overall college experience, and effective solutions and policies to prevent or meaningfully address food insecurity among college students. Research in these identified priority areas may help accelerate action and interdisciplinary collaboration to alleviate food insecurity among college students and play a critical role in informing the development or refinement of programmes and services that better support college student food security needs.
ON HERBERT A. SIMON AND JORGE LUIS BORGES ABOUT FREE WILL
Authors: Crespo Ricardo F.
Published: May 2023

In 1970 Herbert Simon was invited by the Sociedad Argentina de Organización Industrial to deliver lectures on “Business Management in the Technological Era.” He asked for an audience with Jorge Luis Borges, the director of the Argentine National Library. Simon had read Borges’s stories and was particularly fascinated by “La Biblioteca de Babel” (The library of Babel), wherein he discovered that Borges, like him, conceived of life as a search through a labyrinth. The Spanish translation of the interview was published in Primera Plana, an Argentine journal. The brief interview sheds light on some of Simon’s ideas about determinism and free will. His critique on maximizing rationality and his suggested approach to decision making have contributed to enlarge the concept of rationality as construed by standard economic theory. Consequently, it may be argued that Simon is incorporating free will in economics. However, though Simon’s position implies an advancement for the role of free will, the whole context of his ideas conditioned it, thus resulting in a “weak” notion of it. During the course of his conversation with Borges, Simon clarified his personal stance, which is consistent with his ideas. The paper will reveal Borges´s and Simon’s understanding of free will. This paper also contains part of the conversation between Simon and Borges that has not been published previously in English. Introducing it in its entirety is a contribution to the knowledge on Borges’s and Simon’s thought.
Development, Measurement, and Validation of a Managerial Competency Model in Spain

Published: May 2023

Abstract: Modernization of Public Administration (PA), to provide a high-quality service, requires improvements in managerial personnel assessment processes. For this purpose, we developed and validated a management competency model that would enable Spanish PA to enhance organizational achievements and prevent corrupt practices. Relations between managers’ competencies and their performance would be perceived as a fairer assessment of human resources processes and ultimately lead to the promotion of ethical behavior within the organization. We followed a mixed-method approach. Study 1 began with a content analysis of articles referring to managerial competencies, followed by Focus Groups and a Delphi panel procedure with subject matter experts, which resulted in a model of eight competencies. Based on this model, in Study 2, we developed a reliable and invariant-across-gender questionnaire (Public Manager Competencies Questionnaire – PUMACQ), which was validated with composite performance criteria (task, contextual, and unethical pro-organizational behavior), by means of a cross-sectional design survey on public managers from around Spain ( N = 439), using structural equation analyses. Our main results show significant relationships between job performance and the competencies of leadership, communication, engagement with PA, innovation orientation, and ethics. Finally, we discuss the practical applications of the results in the public context.
Opening the Door of Self-Disclosure

Published: May 2023

Abstract: Loneliness is prevalent among iGeneration adolescents who fail to develop close friendships. The present review proposes a proactive approach, advocating that adolescents should be supported in their development of close friendships, as part of social-emotional learning (SEL). As research has found self-disclosure to be an important skill for developing close friendships, adolescents should be guided in this skill. Such guidance is the domain of school counselors and psychologists who could use the organized thinking framework on self-disclosure and the six counseling methods detailed and demonstrated here to support adolescents in this task.
Quantifying the Vertical Transport in Convective Storms Using Time Sequences of Radar Reflectivity Observations

Published: May 2023

A new satellite observation concept to estimate upward air mass flux in convective storms has been proposed using a convoy of small radars that measure reflectivity only. The approach is to analyze a pair of radar reflectivity profiles obtained within 30–120 s of one another, and infer the upward transport above the freezing level and at a nominal 3‐km horizontal resolution from the reflectivities and their temporal change. This paper summarizes the theoretical basis for this approach, with quantitative justification using sensitivity analyses of convection‐permitting model simulations and from ground‐based zenith profiler data. We then describe and quantify the performance of the approach to detect updrafts from the radar observations. Finally, we illustrate the expected performance of retrievals of the vertical transport and evaluate their ability to meet the objectives of the “Investigation into Convective Updrafts” mission, selected by NASA to place in orbit in 2027–2028 a convoy of three identical Ka‐band radars measuring radar reflectivity within their common swath.
Triple‐Element Stable Isotope Analysis of Chloromethane Emitted by Royal Fern and Degraded by Club Moss
Authors: Hartmann S. Christoph , Keppler Frank , Greule Markus , Lauer Rebekka , Horst Axel
Published: May 2023

Chloromethane (CH3Cl) is the most abundant natural chlorinated organic compound in the atmosphere playing an important role in catalyzing stratospheric ozone loss. Vegetation emits the largest amounts of CH3Cl to the atmosphere but its source strength is highly uncertain leading also to large uncertainties in the global budget of CH3Cl. Triple‐element stable isotope analysis may help to reduce uncertainties because it provides additional process‐level information compared to conventional quantification methods. In this study we performed experiments to obtain a first triple‐elemental isotopic fingerprint (2H, 13C, 37Cl) of CH3Cl emitted by a relevant plant species (royal fern, Osmunda regalis). Isotopic values of all three elements showed considerable differences compared to isotopic values of industrially manufactured CH3Cl which bodes well for future applications to distinguish individual sources. Isotopic analysis of potential precursors (rain, methoxy groups) of CH3Cl in plants revealed no measurable change of hydrogen and chlorine isotopic ratios during formation which may provide a simpler route to estimate the isotopic composition of CH3Cl emissions. Plant degradation experiments of CH3Cl were carried out with club moss (Selaginella kraussiana) revealing significant isotopic fractionation for all three elements. The fractionation pattern characterized by epsilon and lambda is inconsistent with known biotic dechlorination reactions indicating a yet unreported biotic degradation mechanism for CH3Cl. Overall, this study provides first insights into the triple‐elemental isotopic fingerprint of plant emissions and degradation. The results may represent important input data for future isotope‐based models to improve global budget estimates of CH3Cl and to explore the yet unknown degradation pathways.

A lightweight multi‐branch network for low‐light image enhancement
Authors: Yu Youjiang , Yuan Cheng , Zhang Kaibing , Wang Xiaohua
Published: May 2023

The generation process of low‐light images is fundamentally complicated due to their multi‐factorial degradation. Many previous methods favorably developed a multi‐branch network for impressive performance. However, the complex structures of multi‐branch networks always incur large computational cost and hinders their applicability in those resource‐limited settings. To alleviate these issues, in this letter a novel lightweight multi‐branch network (LMBN) for low‐light image enhancement is proposed. Specifically, a multi‐branch module and a joint loss are framed to surmount the complex degradation factors of low‐light images. Furthermore, the multi‐branch network is implemented by several heterogeneous and shallow encoder‐decoder modules. The elaborately designed lightweight model facilitates lower computational complexity but maintains impressive enhancement quality. The experimental results performed on three popularly benchmark databases demonstrate that the proposed LMBN shows the superior performance over other state‐of‐the‐art methods, indicating a perfect balance between the model's performance and the computational efficiency.

Published: May 2023

A novel wideband multilayer dual‐podal Vivaldi antenna with broadband characteristics from 5.5 to 20.82 GHz, is presented. Contrary to traditional Vivaldi antennas that are antipodal‐based, this design is realised by placing a pair of podal Vivaldi antennas with corrugated slots on the top and bottom of a substrate stack (consisting of two dielectric layers) using a Bondply. The pair is fed in‐phase with the help of a Strip‐Line (SL) transmission section that is terminated on a radial stub to couple capacitively to the antenna elements. With this technique of electrically coupling a podal Vivaldi pair, improved performance parameters are achieved, specifically: a measured maximum gain of 9.33 dBi, Half Power Beam Width of 126.5° in the H‐plane, and a maximum Front‐to‐Back (F/B) ratio of 14.36 dB with an overall antenna size of 29 × 21 × 1.63 mm. The in‐depth understanding of the working mechanism is supported by a detailed parametric analysis, current distribution, and a clear physical insight into the operating principles. Moreover, a 1 × 4 Vivaldi antenna array is also designed and analysed. A measured maximum gain of the 13 dBi at 15 GHz in the array is achieved along with the wide bandwidth of 6.3 GHz from 10.78 to 17.07 GHz. The array is fed through an SL corporate feed network that ensures in‐phase excitation of all four Vivaldi pairs. A Grounded Co‐planar Waveguide to SL transition is adopted for connecting the 2.92 mm Radio Frequency launcher on the top layer. The very compact geometry of the proposed structure enables its integration into the systems for remote sensing applications.
The transient instability mechanism and stability‐enhanced LVRT control for VSC riding‐through severe grid voltage sag

Published: May 2023

As the grid‐connected interface device of wind and photovoltaic power generation, the voltage source converter (VSC) must pass the low voltage ride‐through (LVRT) test. However, existing literature demonstrates that under weak grid conditions, there is a possibility of severe fluctuations in the terminal voltage of VSC during transiting from the pre‐sag normal operation mode to the LVRT mode. Unfortunately, it will make VSC frequently enter and exit LVRT mode. In order to address the tricky problem of transient instability of VSC riding‐through severe grid voltage sag under the weak grid, in this paper, the full‐order large‐signal model of VSC is established first. Then, based on the established model, the analysis indicates VSC will face the risk of losing stability under the weak grid during LVRT due to current transients. By studying the impacts of low short circuit ratio (SCR) on the basin of attraction of the post‐sag equilibrium point, the intrinsic mechanism of VSC losing stability under weak grid conditions is revealed. Moreover, considering that the transient stability is related to the current control, the stability‐enhanced LVRT control ensuring both small‐signal stability and transient stability of VSC during LVRT is proposed. Finally, the correctness of the above theoretical analysis is verified by real‐time simulation
