Improving Land Surface Temperature Estimation in Cloud Cover Scenarios using Graph-Based Propagation
Authors: Rolland Iain , Selvakumaran Sivasakthy , Shaikh Shaikh Fairul Edros Ahmad , Hamel Perrine , Marinoni Andrea
Published: April 2024

Land surface temperature (LST) serves as an important climate variable
which is relevant to a number of studies related to energy and water
exchanges, vegetation growth and urban heat island effects. Although LST
can be derived from satellite observations, these approaches rely on
cloud-free acquisitions. This represents a significant obstacle in
regions which are prone to cloud cover.In this paper, a graph-based propagation method, referred to as
GraphProp, is introduced. This method can accurately obtain LST values
which would otherwise have been missing due to cloud cover. To validate
this approach, a series of experiments are presented using
synthetically-obscured Landsat acquisitions. The validation takes place
over scenarios ranging from between 10% and 90% cloud cover across
three urban locations. In presented experiments, GraphProp recovers
missing LST values with a mean absolute error of less than 1.1C, 1.0C
and 1.8C in 90% cloud cover scenarios across the studied locations
respectively.
Exploring the Relative Contribution of the MJO and ENSO to Midlatitude Subseasonal Predictability
Authors: Mayer Kirsten J , Chapman William E , Manriquez William A
Published: April 2024

Here we explore the relative contribution of the Madden-Julian
Oscillation (MJO) and El Niño Southern Oscillation (ENSO) to midlatitude
subseasonal predictive skill of upper atmospheric circulation over the
North Pacific, using an inherently interpretable neural network applied
to pre-industrial control runs of the Community Earth System Model
version 2. We find that this interpretable network generally favors the
state of ENSO, rather than the MJO, to make correct predictions on a
range of subseasonal lead times and predictand averaging windows.
Moreover, the predictability of positive circulation anomalies over the
North Pacific is comparatively lower than that of their negative
counterparts, especially evident when the ENSO state is important.
However, when ENSO is in a neutral state, our findings indicate that the
MJO provides some predictive information, particularly for positive
anomalies. We identify three distinct evolutions of these MJO states,
offering fresh insights into opportune forecasting windows for MJO
teleconnections.
Reconnection Signatures in Kelvin Helmholtz Instability in PIC Simulations

Published: April 2024

We performed 2D PIC simulations of Kelvin Helmholtz instability (KHI)
with symmetric and asymmetric density and temperature profiles along the
flow shear with a northward interplanetary magnetic field. The Magnetic
Flux Transport method, field topology and magnetic field minimums are
used to identify the reconnection X-lines. We start to observe the
reconnection signatures such as magnetic field and flow reversals at the
vortex edges in the nonlinear phase of the KHI when the vortices are
rolling up. The number of reconnection regions increases at the
turbulence phase. The signatures eventually decrease and finally
disappear at very turbulent stages of KHI developments. Our results
qualitatively agree with MMS observations of reconnection signatures at
KHI along the magnetospheric flanks.

Resumen: En el contexto  de  la Universidad  de  hoy,   a  menudo  se   pronuncian  estas  tres  palabras  las  cuales  están interrelacionadas y que conllevan un único fin, el ofrecimiento de una educación  de calidad.  La formación de jóvenes investigadores ha sido una estrategia  especialmente útil en el fortalecimiento de los grupos de investigación de  menor desarrollo, los cuales buscan un mejor reconocimiento  para  avanzar a niveles superiores de calificación, sin embargo ésta ha sido poco  utilizada por las Universidades de menor desarrollo, tal es el caso de la Universidad de los Llanos, que después  de 10  años de creado el  programa por parte de Colciencias,   solo ha presentado 3 jóvenes  investigadores,  que después  de recibir la formación, el futuro es aún  incierto. No basta  solamente  que dichos jóvenes sean  formados en  instituciones  de alto nivel académico, sino que deben  existir estrategias   que permitan  su retención  institucional, máxime cuando  la  Universidad  se encuentra  inmersa  en la acreditación voluntaria de los programas  de mayor trayectoria.  De no ser así solo estaríamos  formando un recurso humano calificado para otras Universidades y Centros de Investigación.

Hybrid model for speech emotion recognition of normal and autistic children (SERNAC)
Authors: Siddiqui Maria Andleeb , Haider Najmi Ghani , Nazir Waseemullah , Mustafa Syed Muhammad Nabeel
Published: April 2024

Since the last decade, autism spectrum disorder (ASD) has been used as a general term to describe a wide range of conditions, including autistic syndrome, Asperger's disorder, and pervasive developmental disability. This problem emerges as a decreased ability to share emotions and a greater difficulty understanding others' feelings, leading to increased social communication difficulties. To assist patients with ASD, we proposed a concept that incorporates speech emotion detection technologies, which are widely used in the field of human-computer interaction (particularly youngsters). An algorithm based on a novel method for classifying normal and autistic children's speech emotions is implemented in this article. The training data set is treated to a new approach after all features have been extracted. The technique discussed in this study is the creation of a hybrid algorithm that serves as a classifier for normal and autistic children's speech emotions. Voice emotion recognition can be identified accurately and with a lower error rate. The data collection includes speech samples from 200 normal and 250 autistic groups in four moods (Angry, Happy, Neutral and Sad). As per research findings, the implemented hybrid algorithm for Normal and Autistic Children Speech Emotions (SERNAC) outperformed the existing classifiers by increasing accuracy.

Published: April 2024

Fluid flow through porous media in intricate geometries has been a fascinating and challenging area of study in applied mathematics and engineering. This area has immense significance in several sectors, such as petroleum, food processing, pharmaceuticals, groundwater flow, and nuclear reactors. This research investigates the behaviour of Newtonian fluids in a conduit filled with a permeable medium under combing and separating stream configurations. The finite element method with the Taylor-Galerkin/Pressure-Correction method is applied in the present study. The stream consists of two reversible setups and two unidirectional streams of linear fluids within a channel filled with porous materials, featuring a sudden gap. To obtain steady solutions, a time-dependent numerical approach is employed. The study examines the effect of intensifying inertia, porosity, and variations in flow rates.
Modification of a convolutional neural network for the weave pattern classification
Authors: Akram Noreen , Butt Rizwan Aslam , Qureshi Muhammad Amir
Published: April 2024

The fabric quality in textile industry is characterized by the texture (weave pattern) as it plays a vital role for the production and design of best quality fabric. The earlier proposed automated weave identification methods based on image processing techniques are highly dependent on the lighting conditions. The machine learning methods have been reported to show better accuracy. However, they require very large training datasets, very high processing power and computation time. This study proposes improved accuracy with smaller dataset and reduced computation time by proposing a modification of VGG16 model by adding two additional pooling layers. Using evaluation metrics of both models, the modified model results were analysed according to accuracy, balanced accuracy, and F1-score. On the basis of investigational outcomes, a comparison has been performed with earlier work. The results show that the proposed VGG-16 model is capable to achieve state-of-the-art accuracy and avoid unnecessary activation features by freezing the main convolutional base layers. Ultimately, as evidenced by the performance of the modified VGG-16 deep learning model, the proposed method demonstrated improved accuracy. The study results show that the proposed modified VGG16 algorithm is able to recognize the features of provided database with 90% accuracy and F1-Score ranging from 0.8 to1.

Published: April 2024

Electricity demand increasing day by day with the passage of time, fossil fuels and traditional electricity sources are becoming obsolete. The possibility of dealing with a power deficit and importing oil and gas for electricity generation exists for developing nations like Pakistan. One of the most accessible and affordable sources of renewable energy in the world is solar power generating. Photovoltaic (PV) cell performance is influenced by the environment and the technology used to capture the available energy. The Islamabad region of Pakistan is blessed with an average of 300 days of sunshine a year due to its location in the solar band at 33.7215°N latitude and 73.0433°E longitude. The current study compares and contrasts how Pakistan and South Asian Association for Regional Cooperation (SAARC) countries generate electricity using solar systems. Choosing one geographical place from all SAARC nations, PVSyst software is used to develop and estimate the performance study for solar model cell Panasonic 320Wp, 48V and 1.5 kW Inverter Fronius for a 9.6 kWp load.  Energy supplied into the grid is studied together with various losses that occur in the system, with the choice of PV arrays and other factors remaining the same for comparison study of all SAARC countries. The approach to minimize losses through the utilization of an adjustable tilt angle has been implemented. This study will be useful in estimating and planning the solar energy output in all SAARC nations for the same photovoltaic system, and it will be simple to trade all PV system components in the region.

Published: April 2024

In this work, five different types of animated graphic design ideas (traditional, 2D, 3D, stop motion, motion) were examined on three different textile fabrics (cotton, silk, polyester) through digital printing. Psychological-emotional expressions (openness, conscientiousness, extroversions, agreeableness, and neuroticism) were investigated that influenced the perceptual criteria. Lastly, a quantitative investigation was carried out from a sample of 300 students whose ages varied from 20 to 24 years old for an analysis of aesthetic appeal through a 5-point Likert scale. The results revealed that motion animation design has the most effective aesthetic appeal while the stop motion design pattern has the least aesthetic appeal. Silk fabric samples have better graphic consequences whereas polyester fabric samples have the least. Moreover, individuals with neuroticism emotional personality have the least effective response while agreeableness has the utmost for the sense of aesthetics. 71% of students were accustomed to aesthetic appeal as compared to structural fabrics.

The world has witnessed substantial deterioration of water resources by different effluents. The most reported among effluents that have caused damage to the water resources are azo dyes that need to be expelled by most efficient techniques such as photocatalysis. This specific study has focused on the synthesis and augmentation of TiO2 for the degradation of methylene blue (MB). In this work TiO2 was synthesized by biogenic route using the extract of Citrus paradisi and the synthesized metal oxide (TiO2) was doped with Ag to escalate the photocatalytic degradation of MB. The synthesized biogenic photocatalyst was characterized by employing XRD and FTIR techniques, which confirms the purity of TiO2. The stability of Ag-doped TiO2 photocatalyst was investigated by performing Zeta-potential and the surface morphology was studied thorough FE- SEM. The photocatalytic efficiency of the photocatalysts were evaluated using UV-vis-Spectroscopy. The XRD analysis confirmed the phase purity of synthesized TiO2 and Ag-doped TiO2. The presence of functional groups associated with the TiO2 and Ag-doped TiO2 were also observed through FTIR. The developed photocatalysts via biogenic route were tested for the degradation of MB that exhibited 56.38% for TiO2 and 85.55% Ag-TiO2 in 120mins respectively.

Heart disease stands as the foremost contributor to global mortality in the present era. While a range of medical tests aids in diagnosing various manifestations of heart disease, anticipating its occurrence without resorting to these tests presents a formidable challenge. Machine learning has revealed a potential path for comprehending extensive medical datasets, unearthing concealed insights that elude human observation. Random Forest, Logistic Regression, XG Boost, k-nearest neighbor, and Gradient boosting was used to predict instances of heart diseases based on age and gender in this study. Regardless of the dataset's generalization or gender-specific characteristics, we observed that Random Forest, XG Boost, and K-Nearest Neighbors models exhibit high robustness and minimal sensitivity to hyperparameters. While the prediction accuracy remains consistent among Random Forest, Xgboost, and K-Nearest Neighbors, the crucial features responsible for achieving that accuracy vary among them. This observation indicates that it is important to test different machine learning algorithms when the interest is in prediction and understanding the most important feature(s).

Authors: Chen Xudong , Li Saisai , Shang Yudong , Wang Jun , Zheng Jiaojiao
Published: April 2024

In this study, a facile in situ sintering method has been proposed for
fabricating high strength lightweight mullite whisker network reinforced
proppants. The effect of TiO2 on the microstructure, properties and fracture
behaviours of the mullite whisker network was researched in detail. The
addition of TiO2 promoted the formation of a modified mullite whisker
network structure, which effectively improved the flexural strength. The
sample containing 4 wt.% TiO2 exhibited an excellent flexural strength of
215.25MPa and low bulk density of 1.53 g/cm3 at 1400 ?C. The TiO2-added
mullite whiskers mostly exhibited rod-like crystals with about 0.5- 0.8 ?m
in diameter and 10-15 ?m in length. The as-prepared ceramic proppant showed
excellent properties, such as low breakage ratio (2.19%under 52MPa), low
density (1.36 g/cm3) and low acid solubility (2.28 wt.%).

The development of economic crimes, particularly regarding money laundering and terrorism financing, led to the promulgation of Law Number 8 of 2010 on Prevention of the Crime of Money Laundering and Law Number 9 of 2013 Regarding Prevention and Eradication of Terrorism Financing Crime. The mode of the crime of the two types of crime also then uses the corporation to disguise it. Presidential Regulation Number 13 of 2018 regarding the application of the Know-Your-Beneficial-Owner Principle by Corporations for the Prevention and Eradication of the Criminal Acts of Money Laundering and Terrorism Financing was promulgated to tackle money laundering and terrorism financing using Corporations. There is an unclear basis for the authority to enact that Presidential Regulation and there is a discrepancy between the criteria for Beneficiary Owners causing legal uncertainty. This study aims to find out and examine the fulfillment of the principle of forming statutory regulations which form the principle of recognizing Beneficiary Owners and to find out and study the determination of Beneficiary criteria in that Presidential Regulation in terms of Law on Prevention of the Crime of Money Laundering and Law Regarding Prevention and Eradication of Terrorism Financing Crime. This study uses normative legal research with a law and regulations approach, where the data obtained is analyzed qualitatively, and the conclusions use a deductive way of thinking. The result of this research is that the principle of recognizing the Beneficiary Owner in that Presidential Regulation is in accordance with the principles of legislation formation; however, the determination of Beneficiary Owner criteria is not accurate.

The rapid use of the internet in Indonesia as part of the world community has created dynamics and problems, in the field of information law and electronic transactions as well as human rights, and also related to one's privacy. The government holds the power to regulate the new world, namely cyberspace for internet users in Indonesia. The right to be forgotten is a person's right that must be protected by the state. In this case, through Law No. 19 of 2019 concerning Electronic Transactions and Information. The right to be forgotten in relation to those who are reported on or whose data is stored in public institutions in relation to perpetrators of criminal acts, victims of criminal acts, or related to news of criminal acts can be both positive and negative if it is misused. Someone who is published in the public space that he was once a victim or perpetrator of a crime certainly has the right to be forgotten so that he can improve himself without the shadow of a dark past. On the other hand, public transparency still requires information to be accessed for certain news. For example, criminal acts of corruption. Bearing in mind human rights and public transparency regarding the classification of who is allowed and who is not allowed to use this right, it must be strictly regulated, for example, criminal acts of corruption.

Published: April 2024

Introduction: A systemic instrument is presented to measure the socioemotional network in relation to the partner and the person's perception of the impact of this intimate network on his or her partner for his or her classification. It is based on the idea that a nurtured social network brings positive benefits to one's nuclear partner. In order to verify this assumption both in research and in clinical practice, it is necessary to construct a complex instrument that allows reaching different dimensions within and outside the couple. Objective: The study seeks the construction and validation of the Multidimensional Couple scale to measure seven dimensions in the couple: emotional, cognitive, physical interest, protection, trust, respect and power, as well as an additional dimension to classify the type of couple. Method: An Exploratory Factor Analysis (EFA) and Exploratory Factor Analysis (CFA) were carried out to test the psychometric properties and the adequacy to the theoretical model. A total of 1149 people (71.5% women and 28% men) living in Mexico participated. Result: The presence of a scale formed by 7 dimensions in the couple and a second order factor is confirmed, which can be applied both by adjusting the answers to the couple itself and to other people different from the couple. The goodness-of-fit and reliability indices are satisfactory. Conclusion: This scale provides a psychometric instrument that allows the study of the relationship between the couple.

Published: April 2024

Aim – to investigate and study the clinical and psychological characteristics of persons who were forced to move due to the war in 2022 to provide recommendations for medical and psychological care and support.Material and methods. Diagnostic interviews used in the study are based on screening methods for assessing mental status, in particular depression, anxiety states, the impact of traumatic events, and assessment of psycho-emotional distress in work and everyday activities. The study was supplemented with the SCL-90-R method, which contributed to a better generalization of data on the mental state, and the AAQ-II method, which made it possible to assess the tendency to emotional avoidance as a mechanism of mental adaptation disorders.Results. The presence of clinically significant anxiety-depressive symptoms associated with the impact of traumatic events and causing psycho-emotional distress in everyday life has been demonstrated. Predictor factors determining distress and psychosocial functioning in various areas are described and can be used as targets for medical and psychological interventions. An analysis of gender differences is presented.Conclusions. The main predictors of distress in work and everyday activities were found to be the impact of traumatic experience, tendency to emotional avoidance, and symptoms of depressive states. Men prevailed in the level of distress in significant areas related to work and household maintenance. Medical-psychological interventions for the development of conscious strategies for coping with distress and overcoming emotional avoidance are promising for further research and clinical practice.

Inclusão escolar na atualidade
Authors: Lockmann Kamila , Henning Paula Corrêa
Published: April 2024

O presente artigo põe-se a discutir sobre a inclusão escolar, como uma produtiva ferramenta da governamentalidade neoliberal. Para isso, produz-se tal estudo a partir das contribuições de Michel Foucault sobre governamentalidade e estratégias biopolíticas. Problematiza-se acerca da inclusão escolar como um importante dispositivo de gerenciamento e prevenção do risco social. Constituindo uma rede que engloba elementos heterogêneos, ele articula diferentes saberes, instituições e uma variedade de leis, além de enunciados científicos e organizações arquitetônicas. É pensando nessa rede que a inclusão coloca em funcionamento o dispositivo da governamentalidade. Anuncia-se, então, uma nova forma de governar a população, que transforma a conduta dos indivíduos em objeto da sua ação governamental. Atualmente, nota-se a presença de uma racionalidade política neoliberal, que cria diferentes mecanismos para governar a população. Ao mesmo tempo em que se percebe a existência de políticas de proteção social, também se visualizam algumas iniciativas que pretendem produzir sujeitos autogorvenados, que sejam capazes de manter a si mesmos e de prover os recursos de que necessitam. Sendo assim, a inclusão escolar vem se constituído, no interior dessa rede, que tem o intuito de governar a vida da população, naquilo que ela produz em termos de fenômenos coletivos.
