Potentials of Genetic Algorithm in the Performance of Load Frequency Control using FACT Devices, AVR and SMES for Hybrid Power System in Deregulated Environment
Authors: Kumar Sunil , Gupta Prof (Dr) SK
Published: January 2025

In this article, the interconnection of two areas of a multi-unit hybrid interconnected power system is studied under a deregulated environment. For emergency requirements and energy-efficient building systems, the hybrid power system is studied which consists of several co-generating units thermal, hydro, nuclear, diesel, and gas power. To control the active power of the interconnected system, the Automatic Generation Controller (AGC) control loop is investigated, whereas, to control voltage, a reactive power control loop named automatic voltage regulator is applied. Effective governance requires the use of additional reliable fast energy exchange devices named superconducting magnetic energy storage (SMES) in both areas. The FACT devices considered are thyristor control series compensator (TCSC), Thyristor controlled phase shifter (TCPS), Unified power flow controller (UPFC), and Static synchronous series compensator (SSSC). For tuning of SMES, a Genetic Algorithm (GA)-based proportional integral derivative with a filter (PIDF) controller is applied to optimize integral square error (ISE). The frequency, tie-line power, and voltage profile of both the areas with various options of SMES connected to the system are studied in terms of overshoot, undershoot, rise time, and settling time. A system without SMES and with SMES in both areas are investigated. It is observed that GA-based PIDF controllers considerably enhanced system performance with SMES and SSSC gives better performance compared to other FACT devices. The response among all the FACT devices, SMES with SSSC gives a better response in terms of the settling time of frequency for two areas is settled at 8.25sec and 7.89sec. The modeling of an interconnected hybrid power system with FACT devices, SMES, and Automatic Voltage Regulator (AVR) is done in MATLAB 2016b Simulink.

Published: January 2025

This study introduces a multi-criteria optimization approach using the Grey Wolf Optimizer (GWO) algorithm to determine the optimal capacity, locations of DG units and capacitor banks, and network reconfiguration in distribution systems. The objective function incorporates six key performance metrics: real losses, imaginary losses, voltage variation, voltage stability index, section load ability, and current balancing index. The proposed GWO technique was evaluated on IEEE 33- and 69-bus systems and benchmarked against Genetic Algorithm (GA) and Particle Swarm Optimization (PSO). Results demonstrate that GWO effectively optimizes the placement and sizing of DGs and capacitor banks under diverse conditions, enhancing system performance and reducing active power losses.

De peito rasgado e coração revelado: a correspondência poética de Camilo Castelo Branco e Maria da Felicidade do Couto Browne n’O Nacional em 1849
Authors: Alves Monteiro de Castro Andreia
Published: January 2025

O presente artigo tem como função levantar e analisar os poemas que compuseram a correspondência em verso travada, em 1849, entre os escritores Maria da Felicidade do Couto Browne e Camilo Castelo Branco nas páginas d’O Nacional. Algumas das peças desse diálogo estão presentes nas obras publicadas por ambos, surpreendentemente, outras ainda jaziam esquecidas nas páginas do importante periódico portuense. Nas proximidades das comemorações do bicentenário de Camilo, recuperar e analisar essa troca parece ser de total relevância não apenas devido ao seu valor documental e histórico, mas sobretudo pela sua importância para a compreensão da atmosfera cultural e artística que, certamente, influenciou a produção de um dos maiores nomes da Literatura Portuguesa. Essa também é uma possibilidade de retomar e dar visibilidade à obra de Maria Browne, incontornável para esse processo.

Disruption of cholinesterases and, as a consequence, increased levels of acetylcholine lead to serious disturbances in the functioning of the nervous system, including death. The need for rapid administration of an antidote to restore esterase activity is critical, but practical implementation of this is often difficult. One promising solution may be the development of antidote delivery systems that will release the drug only when acetylcholine levels are elevated. This approach will ensure timely delivery of the antidote and minimize side effects associated with uncontrolled drug release. Here, we describe the creation of a new smart system that serves as a carrier for delivering an antidote (i.e., atropine) and functions as a synthetic esterase to hydrolyze acetylcholine. The nanocarrier was synthesized through microemulsion polycondensation of phenylboronic acid with resorcinarenes containing hydroxy, imidazole, and carboxylic groups on the upper rim. The nanocarrier breaks down acetylcholine into choline and acetic acid. The latter acts on the boronate bonds, dissociating them. This leads to the destruction of the nanocarrier and the release of the antidote. The paper covers the creation of the nanocarrier, its physicochemical and biological properties, encapsulation of the antidote, acetylcholine hydrolysis, and antidote release.

Authors: Ali Siad Dahir , Rasmussen Mette Heidemann , Catalano Jacopo , Frederiksen Christian Husum , Weidner Tobias
Published: January 2025

Scaling of steel surfaces, prevalent in various industrial applications, results in significant operational inefficiencies and maintenance costs. Inspired by the natural hydrophobicity of springtail (Collembola) skin, which employs micro- and nanostructures to repel water, we investigate the application of silicone nanofilaments (SNFs) as a coating on steel surfaces to mitigate scaling. Silicone nanofilaments, previously successful on polymers, textiles, and glass, are explored for their hydrophobic properties and stability on steel. Our study demonstrates the successful coating of stainless steel with SNFs, achieving super-hydrophobicity and resilience under high shear stress and explosion/decompression tests. Scaling experiments reveal a 75.5% reduction in calcium carbonate deposition on SNF-coated steel surfaces. This reduction is attributed to altered flow dynamics near the super-hydrophobic surface, inhibiting nucleation and growth of scale. Our findings highlight the potential of bioinspired SNF coatings to enhance the performance and longevity of steel surfaces in industrial environments.

Authors: Mudau Thizwilondi J. , Sikhwari Matodzi G.
Published: January 2025

Limited father engagement in early childhood education affects children’s social development and perpetuates traditional gender roles, hindering efforts to promote gender equality and positive masculinities. This article investigates how father involvement in the Foundation Phase contributes to fostering gender equality and modelling positive masculinities. Using Bronfenbrenner’s Ecological Systems Theory as a framework, the article employed a qualitative case study design, collecting data through semi-structured interviews and focus groups with 40 fathers, 8 teachers, and 4 school administrators from rural and semi-urban primary schools in South Africa’s Vhembe District. Purposive sampling ensured diverse participant representation. Thematic analysis revealed that active father participation challenges traditional gender norms, models respectful behaviours, and facilitates open discussions on gender roles, thereby promoting gender equality and nurturing positive masculinities. Fathers’ involvement also highlighted the importance of redefining caregiving roles, showcasing the nurturing aspects of fatherhood. To ensure the article’s rigor, trustworthiness was achieved through member checking, peer review, and data triangulation, with ethical considerations such as informed consent and confidentiality adhered to throughout. The article recommends the development of school programs aimed at encouraging father engagement and providing training for educators to facilitate active male participation in early education. These findings contribute to scholarship by emphasizing the transformative role of fathers in promoting gender-equitable, inclusive learning environments and offer practical strategies for enhancing father involvement in early childhood education.

Art-technologies for creating an artistic image: issues of imitation and the transitivity of the creative process
Authors: Sovhyra Tetiana
Published: January 2025

The article reveals certain aesthetic patterns in the creation of augmented reality content, namely the importance of modelling the real environment, transitivity, and simulation of traditional practices of creating sculptural forms. These issues are analyzed on the author’s projects examples organized through the augmented reality use (applications REMS Companion App and MININ Art). An aesthetic patterns interdisciplinary research of augmented reality content perception allows us to draw significant conclusions about the artistic uniqueness of virtual images. The article reveals certain regularities in the creation of augmented reality content, including the peculiarities of imitation of traditional sculptural techniques and materials texture. It has been established that in order to create a realistic embodiment of virtual models in a real environment and to make these objects three-dimensional, it is important to take into account the peculiarities of chiaroscuro. Technologically, this can be done by installing a light source in the virtual scene that will illuminate objects at a certain angle. Consideration of the results of technological experience of content generation suggests that augmented reality allows the artist to create a transitional creative environment by imitating real space. When virtual content is detached from its marker (the image of real space), the specific author’s context is lost. As a result, we can safely talk about the content uniqueness created with the help of augmented reality technology. Having all the signs of artistic creativity, these models can be called augmented reality sculptures – a form of synthetic digital and visual art.

Published: January 2025

Filaments play a crucial role in providing the necessary environmental conditions for star formation, actively participating in the process. To facilitate the identification and analysis of filaments, we introduce Directional and Positional Consistency between Clumps and Filaments (DPConCFil), a suite of algorithms comprising one identification method and two analysis methods. The first method, the consistency-based identification approach, uses directional and positional consistency among neighboring clumps and local filament axes to identify filaments in the position–position–velocity data cube. The second method employs a graph-based skeletonization technique to extract the filament intensity skeletons. The third method, a graph-based substructuring approach, allows the decomposition of complex filaments into simpler subfilaments. We demonstrate the effectiveness of DPConCFil by applying the identification method to the clumps detected in the Milky Way Imaging Scroll Painting survey data set by FacetClumps, successfully identifying a batch of filaments across various scales within 10° ≤ l ≤ 20°, −5

A Search for the O’Connell Effect in Contact Binaries in the Era of Big Sky Surveys. I.
Authors: Kleftogiannis Georgios D. , Christopoulou Panagiota-Eleftheria , Papageorgiou Athanasios
Published: January 2025

Asymmetries between the two maxima of the light curves of contact binaries, known as the O'Connell effect, have been identified using the All Sky Automated Survey, All-Sky Automated Survey for Supernovae, Northern Sky Variability Survey, Optical Gravitational Lensing Experiment, and Optical Monitoring Camera sky surveys. The morphology of the mean light curve has been analyzed for a total of 43,659 objects already classified as contact binaries. After applying several filters and criteria, we present a sample of 797 systems representing the largest sample to date of maxima asymmetries of EW-type binaries with ∣Δm∣ up to 0.13 mag. We also added information on distance and temperature from Gaia DR3 and The Large Sky Area Multi-Object Fiber Spectroscopic Telescope. We investigated the statistical distributions of periods, temperatures, signs of maximum asymmetry, O'Connell effect ratio and light-curve asymmetry indices of asymmetry, and their correlations. While starspots could explain the different maxima asymmetries in stars with convection zones and differential rotations, the discovery of sizeable asymmetric maxima in 161 early-type systems above the upper limit of the Kraft break (T > 6700 K) may indicate a different mechanism. We also report systems with peculiar unequal maxima.

The prevalence of atmospheres on rocky planets is one of the major questions in exoplanet astronomy, but there are currently no published unambiguous detections of atmospheres on any rocky exoplanets. The MIRI instrument on JWST can measure thermal emission from tidally locked rocky exoplanets orbiting small, cool stars. This emission is a function of their surface and atmospheric properties, potentially allowing detections of atmospheres. One way to find atmospheres is to search for lower dayside emission than would be expected for a blackbody planet. Another technique is to measure phase curves of thermal emission to search for nightside emission due to atmospheric heat redistribution. Here, we compare strategies for detecting atmospheres on rocky exoplanets. We simulate secondary eclipse and phase curve observations in the MIRI F1500W and F1280W filters for a range of surfaces (providing our open-access albedo data) and atmospheres on 30 exoplanets selected for their F1500W signal-to-noise ratio. We show that secondary eclipse observations are more degenerate between surfaces and atmospheres than suggested in previous work, and that thick atmospheres can support emission consistent with a blackbody planet in these filters. These results make it difficult to unambiguously detect or rule out atmospheres using their photometric dayside emission alone. We suggest that an F1500W phase curve could instead be observed for a similar sample of planets. While phase curves are time-consuming and their instrumental systematics can be challenging, we suggest that they allow the only unambiguous detections of atmospheres by nightside thermal emission.

Published: January 2025

Minimoons are asteroids that become temporarily captured by the Earth–Moon system. We present the discovery of 2024 PT5, a minimoon discovered by the Asteroid Terrestrial-impact Last Alert System Sutherland telescope on 2024 August 7. The minimoon with heliocentric semimajor axis, a ~ 1.01 au, and perihelion, q ~ 0.99 au, became captured by the Earth–Moon system on 2024 September 29 and left on 2024 November 25 UTC. Visible g, r, i, and Z spectrophotometry was obtained using Gemini North/Gemini Multi-Object Spectrograph on 2024 September 27. The color indices are g − r = 0.58 ± 0.04, r − i = 0.29 ± 0.04, and i​​​​​​​ − Z = −0.27 ± 0.06, and the spectrum best matches lunar rock samples followed by S-complex asteroids. Assuming an albedo of 0.21 and using our measured absolute magnitude of 28.64 ± 0.04, 2024 PT5 has a diameter of 5.4 ± 1.2 m. We also detect variations in the lightcurve of 2024 PT5 with a 0.28 ± 0.07 mag amplitude and a double-peaked period of ~2600 ± 500 s. We improve the orbital solution of 2024 PT5 with our astrometry and estimate the effect of radiation pressure on its deriving an area-to-mass ratio of 7.02 ± 2.05 × 10−5 m2 kg−1, implying a density of  ~3.9 ± 2.1 g cm−3, compatible with having a rocky composition. If we assume 2024 PT5 is from the near-Earth object (NEO) population, its most likely sources are resonances in the inner Main Belt when we compare its orbit with the NEO population model though this does not exclude a lunar origin.
Deep Learning the Forecast of Galactic Cosmic-Ray Spectra
Authors: Du Yi-Lun , Song Xiaojian , Luo Xi
Published: January 2025

We introduce a novel deep learning framework based on long short-term memory networks to predict galactic cosmic-ray spectra on a one-day-ahead basis by leveraging historical solar activity data, overcoming limitations inherent in traditional transport models. By flexibly incorporating multiple solar parameters, such as the heliospheric magnetic field, solar wind speed, and sunspot numbers, the model achieves accurate short-term and long-term predictions of cosmic-ray flux. The addition of historical cosmic-ray flux data significantly enhances prediction accuracy, allowing the model to capture complex dependencies between past and future flux variations. Additionally, the model reliably predicts full cosmic-ray spectra for different particle species, enhancing its utility for comprehensive space weather forecasting. Our approach offers a scalable, data-driven alternative to traditional physics-based methods, ensuring robust daily and long-term forecasts. This work opens avenues for advanced models that can integrate broader observational data, with significant implications for space weather monitoring and mission planning.

L’autrice rapporte ici ce qu’elle retient d’une brève expérience de face-à-face psychanalytique à distance (par Internet) durant la période de confinement imposée par le Covid, et les mois qui ont connu des restrictions dans les rencontres interpersonnelles. Elle ne prétend pas à en tirer des enseignements généraux, mais fait part de ce qu’elle a pu découvrir dans cette situation nouvelle.
Évolution de la place du diagnostic dans la cure
Authors: C. Colin Robert
Published: January 2025

Du temps de Freud coexistaient déjà deux manières complémentaires de penser la clinique. La première est sémiologique, elle ambitionne de poser un diagnostic psychiatrique précis à partir du recensement point par point des symptômes observés. La seconde est nosologique. Elle se fonde sur une attention subjective. Sa force et son efficacité naissent de la singularité du thérapeute, de sa sensibilité, de sa capacité à se comprendre, de sa capacité à interroger psychanalytiquement le sens des symptômes et à émettre des hypothèses pathogéniques. Selon les périodes de l’histoire de la psychanalyse, ces deux manières se sont soit complétées judicieusement, soit ignorées, opposées. Aujourd’hui, l’arrivée des classifications internationales dans le champ de la psychiatrie révolutionne les habitudes des plus jeunes praticiens, en accentuant un clivage préjudiciable entre ses deux manières de penser la clinique.
Perspectives et aménagements de la psychothérapie chez l’enfant
Authors: Deyon Dominique
Published: January 2025

La psychanalyse de l’enfant s’est développée et a permis la création d’outils thérapeutiques et théoriques ouvrant de nouveaux territoires de soin. Ses résultats sont magistralement ignorés par les politiques de santé actuelles. Il est donc urgent de témoigner et de résister à cette méconnaissance.
Freud et le « penser par cas »
Authors: Quintin-Val Géraldine
Published: January 2025

La psychanalyse est-elle une science ou une discipline philosophico-littéraire ? La réponse à cette question, qu’elle consiste en l’une ou l’autre des options, s’impose trop souvent comme une évidence, semblant invalider une question qui ne mériterait même pas d’être posée. Mais la psychanalyse est avant tout un outil thérapeutique. Si elle n’est que littérature, elle n’a pas sa place dans le champ du soin. En revanche, s’il s’agit d’une science, il est nécessaire d’en prouver la scientificité au lieu de la considérer dogmatiquement comme telle. C’est ce que propose de faire G. Visentini (2024) dans Penser et écrire par cas en psychanalyse en décryptant, maillon par maillon, les fondements épistémologiques de la discipline. Par un travail méticuleux d’analyse « au ras des textes » freudiens, l’auteur explicite le bien-fondé et la logique scientifique de la psychanalyse. Il en extrait tous les schèmes de pensée (basaux, médicaux, psychologiques et psychanalytiques) et démontre comment, avec l’invention du cas-démonstration, Freud a créé une nouvelle forme de scientificité. Face au discours univoque de la méthode expérimentale, implicitement posée par les courants néo-positivistes comme la seule manière de faire science, l’ouvrage de Visentini, que nous vous présentons ici, apporte des arguments solides pour défendre le sérieux et la scientificité de la psychanalyse.
Pharmacological Accommodative Changes of Haptic Position and Its Impact on Vault After ICL Implantation
Authors: Shi Meipan , Wei Ruoyan , Zhou Xingtao , Liu Shengtao
Published: January 2025

Purpose

To evaluate dynamic changes in ciliary parameters and Implantable Collamer Lens V4C (ICL) (STAAR Surgical) haptic position using mydriatic and miotic agents and their effects on the central and peripheral vault.

Methods

This study involved 80 eyes from 40 consecutive patients (mean age: 28.05 years; range: 19 to 42 years) examined 3 months after ICL implantation. Patients were randomly assigned to either a mydriasis group or a miosis group. Ultrasound biomicroscopy was used to measure the following parameters at baseline and after pharmacological induction with tropicamide or pilocarpine: ciliary process length (CPL), iris ciliary angle (ICA), final tip point of the ICL haptic (ftICL haptic), central vault (c-vault), mid-peripheral vault (m-vault), and peripheral vault (p-vault).

Results

In the mydriatic group, the proportion of eyes with all ICL haptics in the ciliary sulcus increased from 70.0% to 77.5% after tropicamide administration, whereas in the miotic group, this proportion decreased from 67.5% to 57.5% after pilocarpine administration. The CPL and ftICL haptic increased significantly in the mydriatic group (all
P
< .01) but decreased in the miotic group (all
P
< 0.01). Conversely, the ICA decreased significantly in the mydriatic group and increased in the miotic group (all
P
< .01). The correlation analysis showed no significant relationship between changes in c-vault, m-vault, and p-vault with alterations in CPL, ICA, and ftICL haptic in both groups.

Conclusions

Haptic position contributes to the movement of the ICL optical zone during accommodation, but changes in haptic position were not significantly correlated with changes in the vault.

Application of the Taylor Diagram in Evaluating the Performance of IOL Formulas
Authors: Zhang Bing
Published: January 2025

Purpose

To apply a new method, the Taylor Diagram, and a new concept, the centered root mean square error (cRMSE), in evaluating the performance of IOL formulas.

Methods

The preoperative biometrics were measured with the IOLMaster 700 (Carl Zeiss Meditec) and the postoperative spherical equivalent refraction (SER) was calculated in 888 anonymous patients. The Taylor Diagram was applied to visualize the centered root mean square error (cRMSE) and the correlation coefficient between the predictions and the observations (R
po
). Ten formulas across generations were optimized by zeroing the mean predictive error, including SRK I, SRK II, SRK/T, Holladay I, Hoffer-Q, Haigis, Barrett Universal II, VRF, EVO 2.0, and Næser 2. The RMSE and cRMSE at a range of IOL constants around the optimized constant were calculated for SRK/T, Holladay I, Hoffer-Q, and Haigis.

Results

The Taylor Diagram showed improved performance of formulas across generations and the aggregations of the same-generation formulas. The SRK I performed worst with an RMSE of 0.819 and R
po
of 0.659, and the EVO 2.0 performed best with an RMSE of 0.341 and R
po
of 0.930. At a range of IOL constants, cRMSE is generally much closer to the optimized value than RMSE. At a relatively wide range of constant values, cRMSEs showed no significant discrepancy with the optimized value at the optimized constant.

Conclusions

The Taylor Diagram is a powerful tool for visualizing the performances of IOL formulas. Constant optimization is proved necessary. When the optimization is unavailable, cRMSE is a good approximation.

Rotational Stability and Outcomes of V4c Toric Implantable Collamer Lenses Placed at Different Lens Orientations
Authors: Yang Yukun , Zhu Fengjiao , Ma Yiping , Li Jing , Li Xiaoxi , Yao Xiaoming
Published: January 2025

Purpose

To evaluate the 12-month rotational stability and outcomes of V4c toric Implantable Collamer Lenses (TICLs) (STAAR Surgical) located at two different lens orientations (horizontal or oblique).

Methods

This retrospective study included a total of 403 eyes with TICL implantation, enrolled between January 2021 and December 2022, that were divided into two groups based on the minimum intended angle off the horizontal axis: horizontal with 263 eyes at an angle ±22.5 degrees or less and oblique with 140 eyes at a minimum intended angle of greater than ±22.5 degrees. A comparison was made of the preoperative characteristics, surgical outcomes, secondary surgical interventions, footplate positions, and adverse events at 1, 6, and 12 months postoperatively. The rotation-related factors were analyzed.

Results

At 12 months, there were 243 eyes (92%) in the horizontal group and 130 eyes (93%) in the oblique group that were within ±0.50 diopters (D) of emmetropia. Their rotation proportion was 5.3 % and 5.7%, respectively, and their rotation angle was 9.11 ± 2.84 and 9.96 ± 2.42 degrees, respectively (
P
= .086). TICL footplates were mostly positioned on the ciliary body. No correlation was observed of lens placement axis, vault, or manifest refraction with rotation in both groups (
P
> .05). During the follow-up, no vision-threatening complications were observed in both groups. Rotation cases were successfully addressed via alignment or lens exchange.

Conclusions

TICLs, when implanted across a range of lens orientations, demonstrated favorable rotational stability and postoperative outcomes. The postoperative rotational stability is independent of the placement angle of the TICL.

Znamčenje območij kot pristop k razvoju podeželja v Sloveniji
Authors: Logar Erik
Published: January 2025

Znamčenje se uporablja za upravljanje dojemanja izdelkov, storitev ali območij, s čimer vpliva na pogled deležnikov in postaja ključni del teritorialnega razvoja. V Sloveniji se ta pristop pri razvoju podeželskih območij uporablja že več kot dve desetletji, vendar njegovi učinki še niso bili celovito preučeni. Slovensko podeželje predstavlja priložnost za analizo prostorskih vzorcev in značilnosti znamčenja z vidika vzrokov in učinkov.
V monografiji je znamčenje obravnavano kot prostorski pojav, pri čemer je analizirano njegovo součinkovanje z območjem. Pri raziskovanju je bila uporabljena kombinacija metod, vključno s pregledom literature, spletnim anketiranjem, polstrukturiranimi intervjuji, analizo podatkov v programu Atlas.ti in infografiko. Rezultati kažejo, da procesi znamčenja odražajo družbeno-gospodarske, strukturne in organizacijske značilnosti podeželskih območij.
Analiza je razkrila odstopanja od teoretičnih predpostavk: znamčenje pogosto poglablja razvojne razlike, sektorska usmeritev prevlada nad celovito, posamezni ukrepi pa so vsebinsko nepovezani. Šibka motivacija deležnikov omejuje sodelovanje in vodi v odločanje od zgoraj navzdol, kar zmanjšuje učinkovitost znamčenja.
