Prediction of fire danger index using a new machine learning based method to enhance power system resiliency against wildfires
Authors: Pham Tan Nhat , Shah Rakibuzzaman , Amjady Nima , Islam Syed 
Published: November 2024

AbstractWildfires, which can cause significant damage to power systems, are mostly inevitable and unpredictable. Fire danger indexes, such as the Forest Fire Danger Index (FFDI) and the Canadian Fire Weather Index (FWI), measure the potential wildfire danger at a given time and location. Thus, by predicting these fire danger indexes in advance, power system operators can obtain valuable insight into the potential wildfire risks and can better be prepared to tackle the wildfires. However, due to dependency on weather conditions, these indexes usually have volatile time series, which make their prediction complex. Taking these facts into account, this paper, unlike previous approaches that predict fire danger indexes based on climatological models, develops a machine learning‐based forecast process to predict these indexes using the relevant weather data and past performance. To do this, first, a volatility analysis approach is presented to analyse the volatility level of the time series data of a fire danger index. Afterwards, an effective machine learning‐based forecast methodology using a new deep feature selection model is proposed to predict fire danger indexes. The developed forecast methodology is tested on the real‐world data of FFDI and FWI and is compared with several popular alternative methods reported in the literature.

AbstractCurrent traffic status detection methods heavily rely on historical traffic flow data and vehicle counts. However, these methods often fail to meet the stringent real‐time requirements of state detection, especially on edge devices with limited computing resources.To address these challenges, this study develops a traffic alert model using temporal video frame analysis and grayscale aggregation quantization techniques. Initially, the model uses distance mapping between pixel features and frames of road traffic videos to construct a comprehensive road environment and vehicle segmentation model. The model also establishes a mapping between pixel equidistant lines and actual distances, enabling precise congestion detection. This approach significantly reduces costs associated with traditional traffic detection methods as it does not rely on historical data. Performance evaluation using fixed‐point road monitoring data indicates that the proposed model outperforms traditional traffic state detection models, with a performance improvement of approximately 4.7% to 9.5%. Additionally, the model improves computing resource efficiency by approximately 72.5% and demonstrates substantial real‐time detection capabilities.
A synchronization method based on current orthogonal decomposition considering harmonic components for wireless power transfer system

Published: November 2024

AbstractIn order to improve the wireless power transfer (WPT) system, an active rectifier is commonly used. Synchronization technology is critical for active rectifier. The traditional synchronization method based on zero‐crossing detection (ZCD) is unstable and not suitable for the case with lots of harmonic component in the resonant current. Here, a new synchronization method with harmonic compensation is proposed for the WPT system without the ZCD of the resonant current. A mathematical model is built to analyse and compensate the impact caused by the harmonic on phase angle. Therefore, the proposed method can be applied to the high‐order resonant network like LCC compensated topology where the harmonic component is rich in the resonant current. For verifying the proposed synchronization method, a laboratory prototype is built. The experimental results prove that the system can operate stably with parameter perturbation and different load. The peak transfer efficiency of the system can achieve the 94.5%.

Context. Detached eclipsing binaries (DEBs) allow for the possibility of a precise characterization of their stellar components. They offer a unique opportunity for deriving their physical parameters nearly independent of a model for a number of systems consisting of late-type giant stars. We aim to expand the sample of low-metallicity late-type giant stars with precisely determined parameters.
Aims. We determine the fundamental parameters, such as the mass and radius, or the effective temperature for three long-period late-type eclipsing binaries from the Large Magellanic Cloud: OGLE-LMC-ECL-25304, OGLE-LMC-ECL-28283, and OGLE-IV LMC554.19.81. Subsequently, we determine the evolutionary stages of the systems.
Methods. We fit the light curves from the OGLE project and radial velocity curves from high-resolution spectrographs using the Wilson-Devinney code. The spectral analysis was performed with the GSSP code and resulted in the determination of atmospheric parameters such as effective temperatures and metallicities. We used the isochrones provided by the MIST models based on the MESA code to derive the evolutionary status of the stars.
Results. We present the first analysis of three DEBs composed of similar helium-burning late-type stars that pass through the blue loop. The estimated masses for OGLE-LMC-ECL-29293 (G4III + G4III) are M1 = 2.898 ± 0.031 and M2 = 3.153 ± 0.038 M⊙, and the stellar radii are R1 = 19.43 ± 0.31 and R2 = 19.30 ± 0.31 R⊙. OGLE-LMC-ECL-25304 (G4III + G5III) has stellar masses of M1 = 3.267 ± 0.028 and M2 = 3.229 ± 0.029 M⊙ and radii of R1 = 23.62 ± 0.42 and R2 = 25.10 ± 0.43 R⊙. OGLE-IV LMC554.19.81 (G2III + G2III) has masses of M1 = 3.165 ± 0.020 and M2 = 3.184 ± 0.020 M⊙ and radii of R1 = 18.86 ± 0.26 and R2 = 19.64 ± 0.26 R⊙. All masses were determined with a precision better than 2% and the precision for the radii is better than 1.5%. The ages of the stars are in the range of 270–341 Myr.

Abstract
Background and study aims Patients with primary sclerosing cholangitis and
inflammatory bowel disease (IBD) have a high risk of colorectal cancer. There is no
agreement on the best technique for surveillance for colorectal neoplasia. We aimed to
assess whether chromoendoscopy and/or high-definition endoscopy is associated with
increased detection of neoplasia in patients with primary sclerosing cholangitis
undergoing surveillance compared with when they were not used.
Patients and methods This was a single-center, retrospective, observational
study designed to analyze differences in the detection of neoplasia (adenomatous and
serrated) among patients with primary sclerosing cholangitis and IBD who underwent
annual surveillance between 2010 and 2020. Multilevel logistic regression was used to
adjust for confounders.
Results Ninety-one patients were identified, resulting in 359 colonoscopies with
360 person-years of follow up. Over the study period, 22 of 91 patients (24%) had at
least one neoplastic lesion identified; however, the mean neoplastic lesion rate was
0.87 (54/63) for the primary sclerosing cholangitis-ulcerative colitis subgroup compared
with 0.24 (4/17) for the primary sclerosing cholangitis-Crohn’s disease subgroup.
Chromoendoscopy was associated with a significantly higher detection rate for neoplasia
(odds ratio [OR] 5.58, 95% confidence interval [CI] 2.08–14.9,P=0.001), and this
association remained after adjusting for confounders, including high-definition
endoscopy. High-definition endoscopes had a higher rate of neoplasia detection, but the
significance was lost after adjustment for confounders, including chromoendoscopy (OR
1.93, 95% CI 0.69–5.40, P=0.21).
Conclusions Chromoendoscopy is associated with a higher detection rate for
neoplasia in patients with primary sclerosing cholangitis and IBD even with
high-definition colonoscopes.

Published: November 2024

Objective This study aimed to assess short-term neurodevelopmental outcomes for neonates affected by fetomaternal hemorrhage (FMH) and compare them with an unexposed group.
Study Design A retrospective cohort analysis was conducted within a large integrated medical system spanning from 2008 to 2018. Neurodevelopmental outcomes of neonatal survivors of FMH were compared with matched controls. Clinically significant FMH in survivors was defined by maternal flow cytometry for fetal hemoglobin result of >0.10% and neonatal transfusion requirement. One unexposed infant was identified for each surviving FMH-exposed infant, matched by gestational age at delivery (±1 week), birth year, sex, and race/ethnicity. The primary outcome was a diagnosis of neurodevelopmental impairment, identified using the International Classification of Diseases (ICD), 9th and 10th Revisions (ICD-9 and ICD-10) codes. Results were presented as proportions, means, medians, and interquartile ranges. Comparisons were performed using chi-square and Fisher's exact tests. A Cox proportional hazards regression model was conducted to examine associations between cognitive and developmental outcomes and FMH exposure.
Results Among 137 pregnancies with clinically significant FMH, 80 resulted in intrauterine demise, 57 neonates required blood transfusion, and 4 neonates requiring transfusion demised during birth hospitalization. No significant difference in rates of neurodevelopmental impairment was found between FMH-exposed and unexposed infants (26.4 vs. 24.6%, p = 0.8). Similar findings were observed in preterm (37 vs. 31.6%, p = 0.7) and term neonates (15.4 vs. 14.8%, p = 1.0). Cox regression showed no significant association between neurodevelopmental outcomes and FMH exposure (1.17 [95% CI: 0.61–2.22]; p = 0.6).
Conclusion Despite the significant perinatal morbidity and mortality associated with FMH, surviving infants did not show a significant difference in neurodevelopmental diagnoses compared to matched unexposed infants. However, definitive conclusions are limited due to the rarity of FMH requiring transfusion and the small exposed sample size, warranting further evaluation in a larger cohort.

Effect of human sound component on the sociability of urban public spaces—a case study in Sheffield, UK
Authors: Cao Jingwen , Kang Jian 
Published: November 2024

AbstractSoundscape quality is important for fostering social interactions in urban public spaces. This study focuses on how and to what extent the compositions of the soundscape affect the sociability of urban public spaces where human sound is focused. Four 360° experimental soundscape samples were designed as foreground/background/no human sound type and signal sound type, based on the raw data collected in Peace Gardens, Sheffield, United Kingdom. Following Affordance Theory, sociability was analyzed by the experimental survey through two aspects—suitability and stimulation level—through a questionnaire consisting of Soundscape Quality evaluation (SQE) and Level of Willingness for social interactions (LoW), respectively. 120 participants were recruited in the same site representing the compositions of space users. Results show that only foreground human sound type significantly enhanced both suitability and stimulation levels, other samples were evaluated with either high suitability/low stimulation or low suitability/high stimulation. Results indicate people prefer a human sound dominated soundscape with high complexity and this preference was varied among different companion types and age groups. To achieve high sociability, it is suggested to create a complex and eventful soundscape within the range of pleasantness accompanied by a centripetal spatial form, and concerns users' diverse demographic backgrounds.
Populism and contingency
Authors: Ramos-González Jorge 
Published: November 2024

Abstract
Populism has been examined in depth in the last decades both from theoretical and empirical approaches. Among the
topics that scholars have studied, the ideological flexibility of populist discourses is one of the most controversial and
difficult to analyse. Although a large body of research has explored this peculiar characteristic of populist political
discourses, this paper provides an original interpretation of populism by assessing this flexibility drawing on the importance of
George Sorel’s theory in discourse theory, which could contribute to a better understanding of populist theory. Understanding
populism from a discursive framework could explain the intrinsic contingency of populism and the emergence of both radical right
and radical left populisms. This study aims to trace the theoretical path from the influence of Sorel’s Theory of Myth on populist
discourse theory to its current implications for populist discourses, resulting in the multifaceted nature of populism.
Metaphorical framing of political events through ENTERTAINMENT scenarios

Published: November 2024

Abstract
The article sets out to examine the entertainment source domain and its scenarios as realised in the
media discourse surrounding political events in Belarus in 2021. Metaphorical scenarios are investigated considering different
viewpoints, such as those presented in Lithuanian, German, and Russian media. The methodological framework is a blend of Cognitive
Linguistics and Critical Discourse Studies, embracing the viewpoint (Sweetser, 2012),
Critical Metaphor Analysis (Charteris-Black, 2005), metaphorical scenarios (Musolff, 2016), and framing (Hart, 2014). The
results demonstrate that the entertainment domain acquires multiple scenarios depending on the viewpoint. The evaluation
attached to the scenarios is mostly negative; however, the viewpoint adopted in Lithuanian and German discourses is very
different from Russian discourse. The former is based on Western values and targets the authoritarian regime, whereas the
latter is Russian-centric, with the Western world posited as a major threat to the Belarusian and Russian societies.
Efficient encoding and aligning viewpoints for 6D pose estimation of unseen industrial parts

Published: November 2024

Abstract
Estimating the 6D poses of industrial parts is a fundamental task in automated industries. However, the scarcity of industrial part datasets and the effort involved to retrain networks present challenges when estimating poses for unseen parts. Although a few pre-trained networks demonstrate effectiveness on unseen objects, they often struggle to encode correct viewpoint for unseen industrial parts, which have significant geometrical differences compared to the pre-trained objects. Additionally, they overlook the viewpoint non-uniformity that frequently occurs in industrial settings, resulting in significant 3D rotation errors. To address these issues, a novel 6D pose estimator for unseen industrial parts is proposed. First, a Self-to-Inter (S2I) viewpoint encoder is introduced to efficiently generate discriminative descriptors that capture the viewpoint information of the observed image. The S2I viewpoint encoder utilizes an Inter-viewpoint attention module to facilitate prior viewpoint communication and leverages a saliency descriptor selection strategy to boost inference speed. Second, a viewpoint alignment module (VAM) is established and integrated with the ICP refiner. The VAM aligns non-uniform viewpoints in an analytical paradigm, leading to enhanced efficiency of the refinement process and more accurate final predictions. Experimental results on the LINEMOD dataset demonstrate competitive performance compared to state-of-the-art methods. Furthermore, the experiments conducted on eight unseen industrial parts validate the exceptional generalizability of our method, highlighting its potential in industrial applications.

Published: November 2024

Abstract
Fault diagnosis is critical for safe and reliable operations of quadrotor unmanned aerial vehicles (UAVs), so that timely remedial measures can be taken to reduce negative impacts of faults. This paper presents a real-time actuator fault detection and isolation (FDI) method for quadrotor UAV flight process. First, a linear parameter-varying model is established to describe quadrotor UAV dynamics, which considers measurement noises and external disturbances. Then, an FDI strategy is developed based on directional residuals, in which only one observer-based residual generator is required and

indices are incorporated to balance fault sensitivity and disturbance robustness. A threshold is derived from the

performance condition, and actuator faults are detected through residual evaluation. Furthermore, by introducing fault feature vectors associated with the system model, the faulty actuator is isolated promptly by analyzing directional correlations between generated residual vectors and defined fault feature vectors. Finally, based on a quadrotor UAV platform, the effectiveness and superiority of the proposed FDI method are verified through online trajectory tracking processes.
Optimizing Na2EDTA concentration for enhanced properties of SILAR - deposited CTS thin films
Authors: P Sapna , A K Sijo 
Published: November 2024

Abstract
This study investigates the impact of varying Na2EDTA concentrations on the properties of copper tin sulfide (CTS) thin films deposited on soda lime glass substrates using the successive ionic layer adsorption and reaction (SILAR) method. The aim is to optimize CTS thin film growth for photovoltaic technology applications. CTS thin films were prepared using SILAR with Na2EDTA concentrations of 0.01 M, 0.04 M, and 0.07 M, resulting in samples CTS01, CTS04, and CTS07. Characterization techniques included XRD, SEM, EDAX, FTIR, I-V curves, transmittance spectra, and Tauc plots. The results reveal significant variations in film properties with changing Na2EDTA concentration. XRD patterns indicate polycrystalline films with an orthorhombic CTS phase. SEM images show smooth, dense films with localized clusters. FTIR spectra detect hydrocarbon chains, aromatic rings, and hydroxyl or ether groups. The I-V curves of three samples (CTS01, CTS04, and CTS07) show a voltage-dependent transition from semiconducting to ohmic behavior. The CTS01 exhibits superior conductivity (3.13 × 10−5/Ωm), while the samples’ resistance and conductivity values show an inverse relationship. Transmittance curves display low UV transmittance and high visible transmittance,suggests that the samples are highly absorptive in the UV range and become more transparent in the visible range, indicating potential applications in optical filtering and photovoltaic devices. Tauc plots estimate band gap energies of 3.66, 3.89, and 3.23 eV, indicating high band gap energies suitable for buffer layers in solar cells. The correlation between band gap energy and crystallite size as a function of Na2EDTA concentration is also observed. The study demonstrates the importance of optimizing Na2EDTA concentration for achieving high-quality CTS thin films with desirable properties for photovoltaic applications. The findings highlight the potential of CTS thin films for solar cells, optical filtering, and photonic devices.

Abstract
In this study, we investigate the interface morphology and optical properties of electrochemical poly(3-hexylthiophene) (P3HT) films deposited by electrochemical synthesis using the chronocoulometry technique on tin-doped indium oxide (ITO) and fluorine-doped tin oxide (FTO) and how the substrate used influences in the deposition of the films and their optical and morphological properties, as well as the buffer layer and the interface effect, with and without spin-coating films of poly(3, 4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS). P3HT polymeric films were synthesized and deposited via the oxidation of the 3-hexylthiophene (3-HT) monomer and characterized via Raman spectroscopy. The morphology and thickness of the P3HT layer present in the samples ITO/P3HT, FTO/P3HT, ITO/PEDOT:PSS/P3HT, and FTO/PEDOT:PSS/P3HT were carried out using atomic force microscopy (AFM). The optical and electronic gap energy of P3HT were calculated from UV–vis spectra and cyclic voltammetry curves, respectively. The photoluminescence (PL) spectra showed broad and asymmetrical line shapes fitted by multi-Gaussian functions identifying different emission species. Emission ellipsometry spectroscopy was performed to study the energy transference between adjacent polymer chains. Our results show a higher linear polarized light emitted by ITO/PEDOT:PSS/P3HT film, ∼37%, thus demonstrating a significant decrease in the energy transfer. Based on these results, the efficiency of organic solar cells can be improved via the interaction of the polymer/polymer interface.
