Kritisasi Anakronisme Arkoun terhadap Keislaman dan Kemodernan
Authors: Nurkhalis Nurkhalis , Misbah T. Lembong
Published: February 2024

Arkoun tried to suggest or introduce anachronistic as the beginning of the new Islamic model era. The representative Arab world of Islam does not recognize the world of anachronisms to accept the presence of the activities and creativity of modernity today. The essence of modernity is in fact necessary only in the methodology of open-minded Islamic societies, not converting Muslims to the Islamic worldview. Rethinking, reconstruction and renewal in the modern era are regarded as Islamic opposition due to the application of anachronisms changing the new order of Islam. Anachronism aims to devour Islamic turats (Islamic traditions) but is trapped in Islamic criticism. Islam Kaffah (Islamic perfectionist) will be brought into Islam al-yassar (Islamic Left). An anachronistic deliberation of the approaches used in the past issue of excavation of legal finalization will change according to modernity. Anachronism have been placed modernity as the creation of the advancement of all sides of human life with unlimited activities, creativity and ethos.AbstrakArkoun mencoba mensugestikan atau memperkenalkan anakronistik sebagai dimulainya era model Islam baru. Dunia Arab yang representatif Islam tidak mengenal adanya dunia anakronisme untuk menerima kehadiran aktifitas dan kreatifitas modernitas sekarang. Essensi modernitas sejatinya dibutuhkan hanya dalam metodologi membuka akal masyarakat Islam, bukan mengubah Muslim terhadap worldview Islam. Rethinking, rekonstruction dan renewal di era modern dianggap sebagai oposisi Islam akibat aplikasi anakronisme merubah tatanan baru keIslaman.

THE ALORESE LANDSCAPE TERMINOLOGY: FORM, FUNCTION, AND SEMANTIC REFERENCES IN AN AUSTRONESIAN LANGUAGE IN EAST INDONESIA
Authors: Sulistyono Yunus
Published: February 2024

This paper aims to describe the landscape and seascape terminology of Alorese, an Austronesian language spoken in the Alor archipelago of eastern Indonesia. Alorese uses unique way of expressing landscape terminology by retaining some of its ancestral Austronesian landscape terminology and innovating relatively new forms, functions and semantic references from its neighboring non-Austronesian languages. Previous research show that Alorese has innovated relatively new forms due to contact with its surrounding non-Austronesian languages. The current paper fills the gap where there has not been any discussion regarding the Alorese landscape terminology outside its preposition function. Discussion on cross-linguistic categorization, such as landscapes in areas such as eastern Indonesia is proven to be fruitful. The Alorese linguistic landscapes are expressed through geographical references and some forms appear unique to Alorese's dialectal variations. In general, the reference to elevations and directionalities in Alorese is achieved through geographical references, such as nala kokar ‘towards Kokar (a town)’ or klou lau ‘seawards (lau 'sea')’ rather than generic land form terms, suchas wara ‘westwards’ which is also an Indonesian loan barat ‘west’. Its non-Austronesian borrowed terminologies include words, such as iti dola ‘mountainwards’, containing loanwords from Alor-Pantar (Papuan) languages dol ‘mountain’. The data of this research were gathered from my 2018 and 2020 fieldwork in 14 Alorese villages located across the northern coast of Alor and Pantar as well as the small islands of Buaya and Ternate. Collections of terminologies show variations in the use of words not only depending on the geographical references, but also relative to the neighboring non-Austronesian languages.
Symmetry Constraints Enhance Long-term Stability and Accuracy in Unsupervised Learning of Geophysical Fluid Flows
Authors: Huang Yunfei , Greenberg David S.
Published: February 2024

Fluid dynamical systems are well described by discretized partial
differential equations, but computational costs limit accuracy, duration
and/or resolution in numerical integrations. Recent studies showed that
deep neural networks trained on simulations or PDE-derived losses can
improve cost-accuracy tradeoffs, but purely data-centric approaches
discard physical and mathematical insights and require computationally
costly training data. Here we draw on advances in geometric deep
learning to design solver networks that respect PDE symmetries as hard
constraints. We construct equivariant convolutional layers for mixed
scalar-vector input fields in order to capture the symmetries inherent
to specific PDEs. We demonstrate our approach on a challenging 1D
semi-implicit shallow water scheme with closed boundaries, applying
unsupervised learning with a physics-derived loss function. We report
strong improvements in accuracy and stability of equivariant solvers
compared to standard convolutional networks with the same architectures
and parameter counts. Solver equivariance also improves performance on
new initial conditions not encountered during training, and suppresses
error accumulation in global momentum and energy. Strikingly, these
benefits do not reduce loss values during training, but appear later
during ML-assisted rollouts over time steps. Our results suggest that
symmetry constraints could improve deep learning performance across a
wide range of fluid dynamical tasks, learning algorithms and neural
architectures.
Impact of optical imagery and topography data resolution on the measurement of surface fault displacement using sub-pixel image correlation
Authors: Antoine Solene L , Liu Zhen
Published: February 2024

The amount and spatial distribution of surface displacement that occurs
during an earthquake are critical information to our understanding of
the earthquake source and rupture processes. However, the earthquake
surface displacement generally occurs over wide regions, includes
multiple components affecting the ground surface at different spatial
scales, and is challenging to characterize. In this study, we assess the
sensitivity of optical imagery and topography datasets of different
resolutions to the earthquake surface displacement when using optical
image cross-correlation (OIC) techniques. Results show that the average
noise in the output displacement maps linearly increases with decreasing
image resolution, leading to greater uncertainty in determining the
geometry of the faults and the associated displacement. Fault
displacements are, on average, under-estimated by a factor
~0.7-0.8 when using 10 m compared to 0.5 m resolution
imagery. Our analysis suggests that an optical image resolution of ≤1 m
is necessary to accurately capture the complexity of the ground
displacement. We also demonstrate that sub-meter vertical accuracy of
the digital surface/elevation model (DSM/DEM) is also required for
accurate image orthorectification, and is better achieved using
high-resolution stereo optical imagery than existing global baseline
topography data. Together, these results highlight the measurement needs
for improving the observation of earthquake surface displacement towards
the development of future Earth surface topography and topography change
observing systems.
Dynamic evolution of dayside magnetopause reconnection locations and their dependence on IMF cone angle: 3-D global hybrid simulation
Authors: yi Yongyuan , Lin Yu , Zhou Meng , Pang Ye , Deng Xiaohua
Published: February 2024

We study the dynamic evolution of dayside magnetopause reconnection
locations and their dependence on the interplanetary magnetic field
(IMF) cone angle via 3-D global-scale hybrid simulations. Cases with
finite IMF Bx and Bz but By=0 are investigated. It is shown that the
dayside magnetopause reconnection is unsteady under quasi-steady solar
wind conditions. The reconnection lines during the dynamic evolution are
not always parallel to the equatorial plane even under purely southward
IMF conditions. Magnetopause reconnection locations can be affected by
the generation, coalescence, and transport of flux ropes (FRs),
reconnection inside the FRs, and the magnetosheath flow. In the presence
of an IMF component Bx, the magnetopause reconnection initially occurs
in high-latitude regions downstream of the quasi-perpendicular bow
shock, followed by the generation of multiple reconnection regions. In
the later stages of the simulation, a dominant reconnection region is
present in low-latitude regions, which can also affect reconnection in
other regions. The global distribution of reconnection lines under a
finite IMF Bx is found to not be limited to the region with maximum
magnetic shear angle.
Unfrozen Water Content Estimation: A Comparison between Ensemble and Non-ensemble Machine Learning Models
Authors: Li Jiaxian , Zhou Pengcheng , Ren Junping , Pu Yiqing , Zhang Fanyu , Wang Chong
Published: February 2024

Unfrozen water content (UWC) is a key parameter affecting a variety of
soil physical-mechanical properties and processes in frozen soil
systems. However, traditional estimation models suffer limitations due
to oversimplified assumptions or limited applicable conditions. Given
that, there is a compelling need to explore alternative modeling
approaches that leverage machine learning (ML) algorithms, which have
shown increasing potential in engineering fields. To this end, this
study evaluated and compared six widely known ML algorithms (i.e., three
ensemble models: RF, LightGBM and XGBoost; and three non-ensemble
models: KNN, SVR and BPNN) for modeling UWC based on collected
experimental datasets. These algorithms were optimized and evaluated
using a framework combining Bayesian optimization and cross-validation
to ensure model stability and generalization. The results demonstrated
that the ensemble tree-based methods, particularly LightGBM and XGBoost,
achieved the highest predictive accuracy and superior overall
performance. On the other hand, the nonensemble methods exhibited poorer
generalization abilities. Interestingly, during 10-fold
cross-validation, consistent underperformance was observed for a
particular fold, possibly stemming from the challenges of the data
distribution in that fold after random shuffling. The present study
highlights the effectiveness of ensemble learning approaches, importance
of proper hyperparameter tuning and validation strategies, and intrinsic
modeling challenges arising from the difference between the freezing and
thawing phase change behaviors. This comprehensive ML model comparison
and robust training framework provide valuable guidance on selecting
suitable data-driven techniques for modeling frozen soil properties for
cold regions hydrogeology and engineering practices.
Active tectonics, Quaternary stress regime evolution and seismotectonic faults in southern central Hispaniola: implications for the quantitative seismic hazard assessment
Authors: Escuder-Viruete Javier , Fernández F.J. , Valera F. Pérez , McDermott F.
Published: February 2024

Present-day convergence between Caribbean and North American plates is
accommodated by subduction zones, major active thrusts and strike-slip
faults, which are probably the source of the historical large
earthquakes on Hispaniola. However, little is known of their geometric
and kinematic characteristics, slip rates and seismic activity over
time. This information is important to understand the active tectonics
in Hispaniola, but it is also crucial to estimate the seismic hazard in
the region.

Here we show that a relatively constant NE-directed shortening
controlled the geometry and kinematics of main active faults in southern
central Hispaniola, as well as the evolution of the Quaternary stress
regime. This evolution included a pre-Early Pleistocene D1 event of
NE-trending compression, which gave rise to the large-scale fold and
thrust structure in the Cordillera Central, Peralta Belt, Sierra Martín
García and San Juan-Azua basin. This was followed by a near pure
strike-slip D2 stress regime, partitioned into the N-S to NE-SW
transverse Ocoa-Bonao-La Guácara and Beata Ridge fault zones, as well as
subordinate structures in related sub-parallel deformation corridors.
Shift to D2 strike-slip deformation was related to indentation of the
Beata Ridge in southern Hispaniola from the Early to Middle Pleistocene
and continues today. D2 was locally coeval by a more heterogeneous and
geographically localized D3 extensional deformation. Defined
seismotectonic fault zones divide the region into a set of simplified
seismogenic zones as starting point for a seismic hazard modeling.
Highest peak ground acceleration values computed in the Ocoa Bay
establish a very high seismic hazard.

Published: February 2024

Due to the COVID-19 pandemic, schools, particularly in rural areas, employed Modular Distance Learning (MDL) to ensure educational continuity. Modular distance learning is the current learning modality of primary education, where parents serve as parent-teachers to their children. This study seeks to evaluate the experiences of students and teachers of Elementary School, on modular distance learning during the pandemic. This study used the qualitative method of interviewing nine students and six teachers to learn about their MDL experiences. Data process involves combining related concepts and themes to produce a more structured and organized picture of the data. MDL strengthens family bonding, promotes independent learning, and economizes money and time. However, it is an additional workload for working parents; there needs to be more teacher-student interaction, preventing pupils from socializing and gadget distractions. The article revealed that MDL has positive and negative experiences for teachers and students. Therefore, the impact may vary depending on individual circumstances and adaptability. The study suggests that suitable strategies should address any challenges during implementation and evaluation. Furthermore, teachers must undergo training related to MDL to address existing problems in delivering their lessons.

Authors: Lavenia Jovita , Tiarani Vinta
Published: February 2024

Changes in instructional modes that have occurred can trigger various perceptions and different learning commitments, especially in lectures that are identic to perform hands-on science, such as science courses. This study aims to analyze students’ perceptions of blended learning and face-to-face modes in science courses related to learning commitment after the Covid-19 pandemic. Using phenomenological method, the research was conducted with six students as participants. The data was collected by interview, observation, and documentation techniques. Triangulation was used to validate the data, while a data analysis technique is using Miles and Huberman. The results show that there are differences in students' perceptions and commitments in science courses with both learning modes. Students tend to perceive face-to-face learning more positively than blended learning because activities perform more interactively. Students’ commitments are better during face-to-face learning than during blended learning. Based on the results, this study concludes that positive perceptions shape better learning commitments than negative perceptions.

Authors: Weerawardhana Savindika , Weerakoon Thilina Ganganath , Wimalasena Sulaksha , Moganaraj Nivethan
Published: February 2024

The notion of smart buildings is becoming a global trend. The smart concept is spread not only via buildings but also through cities, transportation, and communication. Many difficulties human beings face can be solved by smart building technology. For example, environmental contamination and resource depletion, such as water and fossil fuels. In Sri Lanka, smart building adoption was at a low level. As a result, the purpose of this research is to assess user comprehension of smart building service preferences and adoption from a Sri Lankan viewpoint. A questionnaire survey is used to obtain data from the community as part of the data collection approach. To achieve the objectives stated above, the data will be analysed using principal component analysis, multiple regression analysis, and Pareto analysis. Results indicated that the majority of Sri Lankans do not grasp smart building technologies. Using principal component analysis, eleven major service preferences were determined. Multiple regression analysis is used to identify the factors that influence service preference. The most essential elements impacting smart building adoption are competency to utilize new technology, preference for smart building attributes, and user satisfaction. This study would be an excellent resource for the future adoption of smart building technologies in Sri Lanka.
Design of a bidirectional EV charger using unit template-based current-controlled synchronous reference frame hysteresis
Authors: Etemesi Ambuli B. R. , Megahed Tamer F. , Kanaya Haruichi , Mansour Diaa-Eldin A.
Published: February 2024

Existing distribution networks were not designed with large-scale electric vehicle (EV) charging infrastructure in mind. Integrating EV charging stations with the distribution grid might lead to power quality (PQ) issues at the point of common coupling (PCC). This work proposes a two-mode, unit template-based synchronous reference frame hysteresis current-controlled (SRF-HCC) three-phase Level 2 EV charger. Mode one focuses on charging the EV battery from the grid (G2V) and utilizes current and voltage control techniques to enhance battery life and performance. Whereas mode two enables the EV’s stored energy to be discharged to the grid (V2G) by the EV user, allowing the sale of power to support the transient effect of the grid voltage and frequency and enhancing the grid’s PQ. The HCC generates switching pulses for both the AC-DC and buck-boost converters. The SRF-based unit template-based control (SRF-UTC) method ensures system stability, voltage, and frequency regulation for power exchange with the grid by combining its efficiency with that of the HCC. The EV charger proposal comprises three primary components: a 3-phase bidirectional AC-DC converter, a bidirectional buck-boost converter, and a filter circuit. The proposed system was modeled using MATLAB/Simulink and evaluated in two case studies to assess its performance.
Experimental test performance for a comparative evaluation of a voltage source inverter: Dual voltage source inverter
Authors: Mangaraj Mrutyunjaya , Sabat Jogeswara , Barisal Ajit Kumar
Published: February 2024

This article proposes an adaptive Kernel-Hebbian least mean square (KHLMS) controller for a dual voltage source inverter (VSI). The recommended topology consists of a distributed energy resource (DER) supported VSI called main VSI (MVSI) and split capacitor supported VSI termed as auxiliary VSI (AVSI). Both the MVSI and AVSI are used to serve the shunt compensation when DER is not integrated with MVSI. The DER scenario is considered to suppress the active power flow shortage in the utility grid. Here, optimal active power flow control (OAPFC) is managed by MVSI and shunt compensation is achieved by AVSI during DER operated mode. Hence, a dual VSI based distribution static compensator (DSTATCOM) facilitates the configuration merits such as reduction in system downtime cost, filter rating switching stress etc. Supremacy of both the neural network (NN) based controller and topology is presented by comparing VSI (called AVSI) in the context of harmonic reduction in source side, voltage balancing, power factor (PF) enhancement, better voltage regulation and OAPFC. The experimental results are obtained through field programmable gate array (FPGA) based hardware units which exhibit radical improvement in the power quality (PQ) conferring as per the international standard grid code (IEEE-519-2017).

Authors: Giang Nguyen Minh , Thang Le Ho Manh , Manh Le Dang , Huong Tran Thi Thu
Published: February 2024

In this paper, a novel design method for quad-band Wilkinson power dividers is proposed. The design method is based on using a quad-band microstrip line. In comparison with other design methods, the proposed method has the advantages of simplicity and low insertion loss. To validate the proposed method, an equal quad-band power divider operating at four bands of 0.7, 1.2, 1.78, and 2.28 GHz was simulated and measured. Good agreement between measured results and simulated ones is obtained. The measured results show that the developed quad-band power divider features low insertion loss of less than 0.75 dB, isolation greater than 20.92 dB, and return loss better than 18 dB at four operating bands.
High Resolution Quadrupole Mass Spectrometer for Ion Beam Processing
Authors: Blahins J. , Bzhishkian A.
Published: February 2024

The mass filtering equipment in the ion beam processing industry plays a vital role. Mass filtering is usually achieved through classic magnetic mass selector techniques. The drawbacks of these techniques are the dimensions, weight, price, and power consumption. We suggest mitigating it by using the electrostatic RF mass selector instead of the magnetic one. We discuss the development of a novel ion beam processing apparatus that employs a QMS filter in a vacuum of superior purity. We describe the experimental setup in terms of part design. The article presents the successful test results of that parts. The article also explains in detail the basic principles and the technical realization of the whole apparatus and presents experimental data showing its high capabilities.
Compensation of Accuracy Error for Time Interval Measurements
Authors: Bespal’ko V. , Litvinenko A. , Stepanovs V. , Kurtenoks V. , Smetska V. , Lapkovskis V.
Published: February 2024

A method of accuracy error compensation for the time interval is examined, allowing to decrease the dependence of accuracy error on the duration of measured intervals and minimising the influence of destabilising factors – ambient temperature changes and the initial deviation of the meter clock generator frequency from the nominal value. The compensation method is based on a calibration procedure that measures precise time intervals under conditions of changing ambient temperature. Then the dependence of the accuracy error on temperature for a particular meter is recorded. Based on these data, a correction table is compiled containing correction factors and temperature values at which these factors were determined. Under real measurement conditions, the correction factor corresponding to the current temperature is determined from the table for measured result correction. The table with correction factor values could be stored in the memory of the meter or processing computer. Experimental verification of the method showed that applying a correction for a meter with a standard XO class clock generator (certificated instability of ±50 ppm) could obtain an equivalent clock generator instability of ±0.15 ppm. The application of the method is efficient in cases where the use of high-end clocking to ensure the required measurement accuracy is not economically feasible.

Analysing Metal Melting Methods for Green Transformation of Scrap Metal: Case Study of Latvia using MCDA and SWOT Analysis
Authors: Terjanika Viktorija , Pubule Jelena , Mihailova Elina , Zlaugotne Beate
Published: February 2024

Metal is one of the most widely used materials in the world. It was a crucial driving force in technological development since the industrial age and continues to push us forward to this day. As metal consumption grows, so does the amount of scrap metal generated. Proper utilization of this waste is crucial in mitigating the negative environmental impacts of the metalworking industry. The processing and use of raw materials is often associated with high resource consumption and high emissions. The utilisation of scrap metal instead of raw metal can lead to up to 10 times less electricity consumption and up to 30 times fewer CO2 emissions. However, selecting the most suitable scrap metal processing technology is crucial, particularly in the case of the metal melting furnace which is the backbone of the industry. The efficiency of this process determines the environmental indicators for the entire scrap metal melting process. This paper conducts an analysis of 8 types of metal melting furnaces based on 11 environmental criteria. Furthermore, a SWOT analysis is conducted to evaluate the efficiency of the metal smelting process in Latvian metalworking enterprises and the potential for future expansion.

Objective: The article aims to analyze the bidding modalities and the existence of sustainability criteria in the bidding notices of the municipality of Teófilo Otoni/MG based on the AGU's National Guide to Sustainable Contracting.
 
Theoretical background: In order to respond to society's demands, the Public Administration needs to use goods and services supplied by third parties selected through a formal administrative procedure called bidding, which must include socio-economic sustainability criteria so that public purchases contribute to sustainable national development.
 
Method: An exploratory and descriptive study was carried out, based on current legislation, recent articles and doctrine on the subject, as well as on the municipality's electronic portal, where 154 processes for contracting goods and services were found for the year 2021.
 
Results and conclusion: It was found that the municipality needs to adhere to greater specifications for the objects it bids for, especially with regard to certifications from competent bodies, in order to ensure sustainability in its purchases.
 
Research implications: The correlation between public procurement, bidding and sustainability presented in the research is of paramount importance in order to assess how the Public Administration can use its purchasing power to collaborate with sustainable national development.
 
Originality/value: The study is original and provides the academic community with a local examination that better reflects the reality in the municipality surveyed in terms of the actions of government management in relation to sustainability based on its purchasing processes.

Authors: Oktyabr'skaya Ol'ga Svyatoslavovna
Published: February 2024

The article explores the genre features of a vacation literature about a children's health camp of the late XX – early XXI centuries. Both the traditions of the story about the pioneer camp of the twentieth century and the original features of modern literature for children and adolescents are revealed. The article actualizes the topics of the relationship between adolescents and children in a new team, the problems of growing up and socialization. A fairly extensive typology of child and adolescent characters relevant to modern reality is presented. The significance and importance of this article is due to the importance of the problems posed, as well as modern and practically unexplored research material, which are the works of V. Krapivin, T. Kryukova, M. Panteleeva, T. Mikheeva, etc., which are only included in scientific circulation. To understand these aspects, the following research methods are used in the article: comparative, hermeneutical and comparative typological methods. With the help of a systematic approach, an analytical study of the ways of communication between children and adolescents, their socialization and self-realization in a vacation story is provided. The main result of this work is the study of different types of characters of children and adults, ways of their interaction and ways of self-realization. The study of practically new and little-studied artistic material that arouses genuine interest among teenagers themselves becomes relevant in this article. At the same time, the following tasks were solved: identifying key aspects of growing up and socialization of a child / teenager; analyzing the relationships of children in the novels of V. Krapivin, T. Kryukova, M. Panteleeva, T. Mikheeva and other writers; determining the features of the development of the main storylines and the imaginative system of the analyzed stories, as well as the genre originality of the works under study. The key aspects of the article were questions about the genre nature of the stories, the typology of child and adolescent characters, and the moral aspects of growing up a child.
Measles to Misfortune: A Case Report on Subacute Sclerosing Panencephalitis
Authors: Medhi Deepanjali , Thakuria Himasree
Published: February 2024

Subacute sclerosing panencephalitis (SSPE) is a progressive neurological disorder of children or young adults caused by measles infection. An abnormal immune response to the virus is said to cause brain inflammation, which may last for years. Mortality rate of the disease is around 95%. In this case report, we present the case of a 15-year-old unimmunized boy from rural Assam who presented with progressive sudden jerky movements of his limbs for 2 months, along with difficulty in doing his daily activities and forgetfulness. Although he was initially admitted with a provisional diagnosis of seizure disorder and treated with tab sodium valproate and tab clobazam, his mother, revealed a history of measles infection at 7 years of age. His Electroencephalogram (EEG) reports and CSF IgG measles antibody findings were suggestive of SSPE. He was immediately started on Tab Isoprinosine at adequate doses, but he later succumbed to his illness within 3 months of the onset of symptoms. Immunization of children with the measles vaccine plays a significant role in averting this deadly condition.

The aim of this series is to report diverse ocular features noted in patients during the induction phase in acute myeloid leukemia (AML). Three female patients undergoing induction therapy for AML reporting for various ocular complaints were examined. Detailed history, including the onset of AML and chemotherapy and any past ocular or systemic ailment, was taken. Best-corrected visual acuity, anterior segment, and posterior segment examinations were performed. Intraocular pressure was measured, and color vision was tested. Routine hematological, and biochemical investigations and imaging were done when required. Patients with abnormal parameters were referred to an oncologist for management. A varied spectrum of ocular manifestations was noted in these three female patients, including preseptal cellulitis, orbital cellulitis, and subhyaloid hemorrhages. Immediate treatment was given to patients with vision-threatening conditions in consultation with an oncologist and otorhinolaryngologist, and patients responded well to the treatment. Owing to its cytoreductive action, AML induction therapy exposes the patient to various adverse events, causing significant ocular and systemic morbidity. All the diagnosed patients of AML are recommended to undergo a baseline ocular assessment.
