Attitude Algorithm of Gyroscope-Free Strapdown Inertial Navigation System Using Kalman Filter
Authors: Jiang Xiong , Liu Tao , Duan Jie , Hou Maosheng
Published: February 2024

A gyroscope-free strapdown inertial navigation system (GFSINS) solves the carrier attitude through the reasonable spatial combination of accelerometers, with a particular focus on the precision of angular velocity calculation. This paper conducts an analysis of a twelve-accelerometer configuration scheme and proposes an angular velocity fusion algorithm based on the Kalman filter. To address the sign misjudgment issue that may arise when calculating angular velocity using the extraction algorithm, a sliding window correction method is introduced to enhance the accuracy of angular velocity calculation. Additionally, the data from the integral algorithm and the data from the improved extraction algorithm are fused using Kalman filtering to obtain the optimal estimation of angular velocity. Simulation results demonstrate that this algorithm significantly reduces the maximum value and standard deviation of angular velocity error by one order of magnitude compared to existing algorithms. Experimental results indicate that the algorithm’s calculated angle exhibits an average difference of less than 0.5° compared to the angle measured by the laser tracker. This level of accuracy meets the requirements for attitude measurement in the laser scanning projection system.

Published: February 2024

Organic acids produced by biota have been shown to accelerate the dissolution of minerals, possibly creating biosignatures in either reacting solutions or the solid materials. We tested aqueous alteration of serpentinite in three groups of solutions: inorganic acids, organic acids created through abiotic processes (termed “abiotic–organics”), and organic acids created through biotic processes (termed “biotic acids”) over a range of temperatures relevant to conditions on Mars and Europa. A total of 48 batch reactor experiments were carried out at 0 °C, 22 °C, and 62 °C in 16 different acids at pH 2.6 over 28 days. Additional experiments were conducted in sulfuric acid solutions to assess aqueous alteration in sulfate-rich environments. These results show that biotic acids accelerate serpentinite dissolution compared to the control inorganic acid, whereas abiotic–organic acids have little or no effect. Sulfuric acid enhances serpentinite dissolution over nitric acid. Secondary precipitates found in the presence of biotic acids were consistently enhanced in Mn, Ti, and W. We propose that these preferentially released elements and secondary minerals may be potential biosignatures. We also show that the release of the rock-forming elements Mg and Si is correlated with stability constants for the metal–acid aqueous complex, providing a possible mechanistic interpretation of the observed results.
Mineralogy and Sr Isotope Characteristics of Dahua Stratified Tremolite Nephrite and Host Rocks, Guangxi Province, China
Authors: Zhang Yuye , Yu Haiyan , Lan Ye , Ruan Qingfeng
Published: February 2024

The tremolite nephrite deposit in Dahua county, Hechi City, Guangxi province, China is a new genetic type of nephrite deposit. It is hosed by Mg-poor limestone (~1.30 wt.% MgO) and intruded by diabase (~45 wt.% SiO2). The Mg and Si contents of these rocks are lower than those of the tremolite (58.18 wt.% SiO2, 13.18 wt.% CaO, 24.16 wt.% MgO), indicating an obviously insufficient source for the metallogenic material that generated the deposit. In particular, some tremolite nephrite ore bodies have no clear contact metamorphism between the host and intrusive rocks, which have the characteristics of stratified mineralization (stratified tremolite nephrite). The origin and mineralization of stratified tremolite nephrite remain poorly constrained. To address this shortcoming, the mineralogy, geochemistry and Sr isotopic of host rock, altered marble, stratified tremolite nephrite and intrusive rock in the Dahua stratified tremolite nephrite deposit were studied. The results show: stratified tremolite nephrite mainly consists of aggregates of microcrystalline-cryptocrystalline tremolites with content exceeding 95%. The in situ rare earth elements (REEs) distribution pattern of hydrothermal calcite in the contact position between stratified tremolite nephrite and marble is similar to that of marine carbonate rock, showing obvious enrichment of HREE, which is different from calcite in limestone and marble. 87Sr/86Sr of stratified tremolite nephrite is relatively uniform, with an average value of 0.7070, within the range of Permian seawater. The mean value of Y/Ho in the hydrothermal calcite is 51.24, indicating that the marine fluid has not been impregnated by terrigenous materials. In summary, the hydrothermal fluid rich in Ca and Si is formed after marine carbonate rocks are altered by marine fluids. Hydrothermal fluids alter diabase rocks formed by altered minerals like titanite, chamosite, zoisite, etc. This process leads to the formation of metallogenic hydrothermal fluids abundant in Si, Ca, Fe and Mg. The metallogenic hydrothermal fluids migrate in faults and fractures of marble and crystallize to form tremolite nephrite under suitable ore-forming conditions.
Feature-Assisted Machine Learning for Predicting Band Gaps of Binary Semiconductors
Authors: Huo Sitong , Zhang Shuqing , Wu Qilin , Zhang Xinping
Published: February 2024

The band gap is a key parameter in semiconductor materials that is essential for advancing optoelectronic device development. Accurately predicting band gaps of materials at low cost is a significant challenge in materials science. Although many machine learning (ML) models for band gap prediction already exist, they often suffer from low interpretability and lack theoretical support from a physical perspective. In this study, we address these challenges by using a combination of traditional ML algorithms and the ‘white-box’ sure independence screening and sparsifying operator (SISSO) approach. Specifically, we enhance the interpretability and accuracy of band gap predictions for binary semiconductors by integrating the importance rankings of support vector regression (SVR), random forests (RF), and gradient boosting decision trees (GBDT) with SISSO models. Our model uses only the intrinsic features of the constituent elements and their band gaps calculated using the Perdew–Burke–Ernzerhof method, significantly reducing computational demands. We have applied our model to predict the band gaps of 1208 theoretically stable binary compounds. Importantly, the model highlights the critical role of electronegativity in determining material band gaps. This insight not only enriches our understanding of the physical principles underlying band gap prediction but also underscores the potential of our approach in guiding the synthesis of new and valuable semiconductor materials.
Impact of Geometric Input Fibers’ Core Positioning on the Adiabaticity of Photonic Lanterns
Authors: Huang Bin , Li Meng , Ping Hangze , Wang Jiaqi , Li Xuan , Shao Xiaopeng
Published: February 2024

Photonic lantern is a key device in space division multiplexing (SDM) system. The key challenge of a photonic lantern is mode scalability, which requires the taper length to increase nonlinearly as the mode number scales up. The traditional photonic lantern fabrication method requires stacking the input fibers into the hollow, low-index outer cladding before tapering. It implicitly sets geometric constraints on the input fibers’ core positioning. We propose a photonic lantern design with drilling preform and reduced cladding fibers to lift these constraints and make photonic lanterns more adiabatic. By analyzing the effects of loosening the constraints on the adiabatic requirement of a three-mode photonic lantern, we find further progress could be made to alleviate this adiabatic requirement. The optimal structure for our design is proposed and demonstrated through the beam propagation method (BPM). Our findings could help further improve the mode scalability of photonic lanterns.

Published: February 2024

The North China Plain has a typical winter wheat–summer corn double-cropping pattern. The effects of nutrient deficiency conditions on the root characteristics and yield of summer corn in the double-cropping system were studied for four years. Long-term monotonous fertilization patterns undermine crop rotation systems and are detrimental to the sustainability of agricultural production. To complement the development of rational fertilization strategies by exploring the response of crop rotation systems to nutrient deficiencies, an experiment was conducted in a randomized complete block design consisting of five treatments with three replicates for each treatment: (1) an adequate supply of nitrogen and phosphate fertilizers and potash-deficient treatment (T1); (2) an adequate supply of nitrogen and potash fertilizers and phosphorus-deficient treatment (T2); (3) an adequate supply of phosphorus and potash fertilizers and nitrogen-deficient treatment (T3); (4) nutrient-sufficient treatment for crop growth (T4); and (5) no-fertilizer treatment (CK). The results showed that different nutrient treatments had significant effects on the root length density (RLD), root surface area density (RSAD), and root dry weight density (RDWD) in summer corn. At the physiological maturity stage (R6), the root indexes of RLD, RSAD, and RDWD were significantly higher in the 0–20 cm soil layer in T4 compared to CK, with an increase of 86.2%, 131.4%, and 100.0%, respectively. Similarly, in the 20–40 cm soil layer, the root indexes of T4 were 85.7%, 61.3%, and 50.0% higher than CK, with varied differences observed in the other nutrient-deficient treatments. However, there was no significant difference among the treatments in the 40–60 cm layer except for T4, whose root index showed a difference. The root fresh weight and root dry matter in T4, T3, T2, and T1 were increased to different degrees compared with CK. In addition, these differences in root indexes affected the annual yield of crops, which increased by 20.96%, 21.95%, and 8.14% in T4, T2, and T1, respectively, compared to CK. The spike number and the number of grains per spike of T4 were 10.8% and 8.3% higher than those of CK, which led to the differences in summer corn yields. The 1000-kernel weight of T4, T2, and T1 were 9.5%, 8.8%, and 7.4% higher than that of CK, whereas the determining nutrient was nitrogen fertilizer, and phosphorus fertilizer had a higher effect on yield than potassium fertilizer. This provides a theoretical basis for the effect of nutrient deficiency conditions on yield stability in a double-cropping system.

Published: February 2024

Aboveground biomass (AGB) serves as a crucial measure of ecosystem productivity and carbon storage in alpine grasslands, playing a pivotal role in understanding the dynamics of the carbon cycle and the impacts of climate change on the Qinghai–Xizang Plateau. This study utilized Google Earth Engine to amalgamate Landsat 8 and Sentinel-2 satellite imagery and applied the Random Forest algorithm to estimate the spatial distribution of AGB in the alpine grasslands of the Beiliu River Basin in the Qinghai–Xizang Plateau permafrost zone during the 2022 growing season. Additionally, the geodetector technique was employed to identify the primary drivers of AGB distribution. The results indicated that the random forest model, which incorporated the normalized vegetation index (NDVI), the enhanced vegetation index (EVI), the soil-adjusted vegetation index (SAVI), and the normalized burn ratio index (NBR2), demonstrated robust performance in regards to AGB estimation, achieving an average coefficient of determination (R2) of 0.76 and a root mean square error (RMSE) of 70 g/m2. The average AGB for alpine meadows was determined to be 285 g/m2, while for alpine steppes, it was 204 g/m2, both surpassing the regional averages in the Qinghai–Xizang Plateau. The spatial pattern of AGB was primarily driven by grassland type and soil moisture, with q-values of 0.63 and 0.52, and the active layer thickness (ALT) also played a important role in AGB change, with a q-value of 0.38, demonstrating that the influences of ALT should not be neglected in regards to grassland change.

Authors: Iermakov Nadia , Stern Nehemia
Published: February 2024

This article analyzes the contribution of women to the Soviet Union’s Jewish movement. We argue that an assessment of the personal stories of Jewish female activists in the former Soviet Union reveals a uniquely meaningful impact on the exodus of Jewry from the Soviet Union, the image of the Soviet Jewish struggle in the international arena, and the establishment of a human rights movements in its support. We explore who these women were, their personal identities, and through what factors they became so successful as prominent leaders in their communities as well as within international organizations. More broadly, by highlighting the link between women’s human rights activities and personal life stories, this article emphasizes a more nuanced analysis concerning the complexity of heroism within national freedom movements through its impact on their careers, mental health, and future destinies.
Cooperation with Persons with Intellectual Disabilities: Reflections of Co-Researchers Associated with Conducting Inclusive Research
Authors: Ćwirynkało Katarzyna , Parchomiuk Monika , Wołowicz Agnieszka
Published: February 2024

Traditionally, persons with intellectual disabilities in Poland have been researched on and treated as not competent enough to research with. Despite its scientific merit and practical usefulness, inclusive research involving persons with intellectual disabilities as co-researchers has only recently become a subject of interest in this country. The added value of inclusive projects should be analysed from two standpoints, i.e., those of co-researchers with disabilities and co-researchers without disabilities. In this article, we discuss the latter perspective, focusing on Polish researchers without disabilities who have experience in conducting inclusive research with persons with intellectual disabilities. The key aspect of the analyses was to highlight the potential of persons with intellectual disabilities as co-researchers. As a result, we have determined several important aspects of inclusive research in the relational perspective involving co-researchers with intellectual disabilities and co-researchers without intellectual disabilities and the community perspective. The analyses identified four superordinate themes: building relationships in the research team; opportunities and constraints associated with the implementation of inclusive projects; institutional barriers; and the importance of the role of a co-researcher without intellectual disabilities. Implications for further research and practice are discussed.

The United Nations Sustainable Development Goals (SDGs), established in 2015, are binding targets for monitoring the sustainable status of all countries in the world. Developing localized SDGs indicator systems, assessing SDGs progress comprehensively, and creating policy tools have gradually become the hotspots of scientific research and practical application of the SDGs. To systematically sort out the research status of the SDGs progress and identify problematic gaps, this paper uses bibliometric methods to analyse the scientific knowledge mapping of SDGs research, sort out the general characteristics, scientific cooperation, cutting-edge hotspots and future research trends of SDGs research. Besides, this paper promotes the integration of academic research into concrete practice by linking it to mainstream SDGs progress reports. The results show that: ① The amount of SDGs research literature in 2015–2022 is on a growing trend, and the existing research is characterised by multidisciplinary crossover. Research institutions such as Utrecht University, the Chinese Academy of Sciences, and the University of the Chinese Academy of Sciences have contributed the most to SDGs research. ② The research hotspots include the SDGs practice of different responsible subjects, the comprehensive assessment of the progress of SDGs, the scientific research of SDGs indicators, and the research on the interaction between the goals of SDGs. ③ Environmental issues, indicators, energy transition, education and agriculture are the hot directions of SDGs research. Energy saving and carbon reduction, sustainable practices of supply chain management, and promoting the progress of environmental dimension goals are the focus of subsequent research. According to the results of the bibliometric analysis, future SDGs research should pay attention to strengthening multi-party cooperation, using innovative technologies to support the assessment of SDGs progress, and formulating sustainable development strategies.
Carbon Accounting in the Digital Industry: The Need to Move towards Decision Making in Uncertainty
Authors: Samuel Gabrielle , Lucivero Federica , Knowles Bran , Wright Katherine
Published: February 2024

In this paper, we present findings from a qualitative interview study, which highlights the difficulties and challenges with quantifying carbon emissions and discusses how to move productively through these challenges by drawing insights from studies of deep uncertainty. Our research study focuses on the digital sector and was governed by the following research question: how do practitioners researching, working, or immersed in the broad area of sustainable digitisation (researchers, industry, NGOs, and policy representatives) understand and engage with quantifying carbon? Our findings show how stakeholders struggled to measure carbon emissions across complex systems, the lack of standardisation to assist with this, and how these challenges led stakeholders to call for more data to address this uncertainty. We argue that these calls for more data obscure the fact that there will always be uncertainty, and that we must learn to govern from within it.

The Community Resilience Measurement of Tourism Village in The Special Region of Yogyakarta against The COVID-19 Pandemic
Authors: Putri Shinta Permana
Published: February 2024

This article or articles aims to measure the resilience index of tourist village communities in DIY, especially in independent and developed tourist villages, and find the factors that influence it. The problem is focused on the biggest impact of the COVID-19 pandemic faced by local communities that have a large dependence on tourism activities. This research is quantitative. Data was collected through a questionnaire survey conducted with the community of tourism village entrepreneurs in DIY. This research focuses the sample on independent and developed tourist villages that are more prepared to face the pandemic. A total of 130 samples were taken with a confidence level of 92% based on the Slovin formula. The first research objective was analyzed by adopting the HCRI (Household Climate Resilience Index) calculation and the second objective was analyzed using multiple linear regression analysis. HCRI calculations are analyzed with the help of tables, percentages, and HCRI models which are used to assess community resilience based on respondents' responses to 31 resilience indicators. Resilience weights of 1-5 are given to indicators classified on a Likert scale, namely very high (5), high (4), medium (3), low (2), and very low (1), which means household resilience increases as the calculated value increases. The final results of this calculation are classified into five categories starting from very low resilience to very high resilience. The results of the analysis show that communities in developed and independent tourist villages in DIY have relatively high resilience in facing the COVID-19 pandemic. This resilience is influenced by economic, institutional, and social capital factors. However, tourist villages in DIY still need to be aware of the threat of vulnerability that may still occur during the COVID-19 pandemic in 12 indicators related to the economic condition of the community. These results have implications for the need to increase community resilience in developed/independent tourist villages by considering vulnerability factors in this research. In this case, both the government and tourist village managers are advised to focus more on programs to improve the quality of tourism business actors' resources and also the ability to mitigate economic losses after the COVID-19 pandemic to maintain the stability and sustainability of the economy of tourist village communities.

Authors: Nurjannah Nurjannah , Azizah Noor
Published: February 2024

This article aims to explain the phenomenon of bullying from the perspective of Islamic criminal law, specifically focusing on the perpetrators of bullying that caused the death of the victim according to Islamic law. This research approaches the issue using normative legal research methods and literature review. The research method is further detailed to include data collection through legal analysis of relevant laws and scientific literature on bullying. The results concluded that bullying is a prohibited act, which results in physical and mental harm to the victim. In the context of Islamic criminal law, sanctions for bullying differ between adult perpetrators and minors. Adult perpetrators who cause injury, loss, or death to the victim may be subject to severe penalties such as hudud, qishash, and ta'zir. In contrast, if bullying is committed by minors, they may be subject to ta'zir punishments, including diyath, kaffarah, alternative or substitute punishments ('uqubât al-badilâh), which aim to educate and deter the perpetrators and others from repeating similar acts. This comprehensive approach to research methodology provides a deeper understanding of the validity of the findings in the context of Islamic jurisprudence.

Authors: Andriksen Herdy , Avianto Donny
Published: February 2024

The existence of endemic animals typical of Central Kalimantan, such as orangutans and hornbills, is included in the protected species situation because the population numbers have increased slightly along with the clearing of land for the plantation sector, making orangutan and hornbill areas that should be beautiful and natural disappear. Because of this, a medium for conveying information and a unique introduction to the public is needed to know how important it is to know and know the various endangered species in Central Kalimantan to preserve animals. Therefore, this research aims to create an application for Central Kalimantan endemic animals using Mobile-based Augmented Reality to introduce Central Kalimantan's rare animals, starting from the area of residence, characteristics, leading food, and information about animal habitats. The application development process uses the Markerless Augmented Reality (AR) method, which displays 3D objects without using unique markers such as photos or images. The application development stage includes the planning, design, data collection, 3D object creation, application development and application testing using Blackbox testing with the Text Case method, which produces application testing descriptively explaining the application work process. The application for displaying 3D objects was tested in 5 trials, with an average of 5 seconds, and the marker appeared to display 3D objects. This application can have an impact on progress in the field of informatics as a medium for delivering information and learning media using Augmented Reality Markerless.

Published: February 2024

This research investigated ensemble clustering algorithms and dimensionality reduction for fire zone mapping, specifically DBSCAN + UMAP. We evaluated six clustering methods: DBSCAN, ensemble DBSCAN, DBSCAN + UMAP, ensemble DBSCAN + UMAP, HDBSCAN and Gaussian Mixture Model (GMM). We evaluated our results based on the Silhouette Score and the Davies-Bouldin (DB) index, emphasizing handling irregular cluster shapes, smaller clusters and resolving incompact clusters. Our findings suggested that ensemble DBSCAN + UMAP outperformed five other methods with zero noise clusters indicating clustering results are resistant to outliers, leading to a clearer identification of fire-prone areas, a high Silhouette Score of 0.971, indicating accurate cluster separation of distinct areas of potential fire hazards and an exceptionally low DB Index of 0.05 that indicates compact clusters to identify well-defined and geographically concentrated areas prone to fire hazards. Our findings contribute to the advanced techniques for minimizing the impacts of fires and improving fire hazard assessments in Indonesia.

Published: February 2024

In order to fabricate multi-layered artificial blood vessels, bubble-surrounded cells were retained on the wall in a flow channel using the phase sweeping of interferential acoustic field. First, spatial distribution of acoustic intensity was defined to evaluate retention performance. Comparing between various acoustic fields, we found appropriate acoustic intensity for retention of the cells. Next, phase sweeping of the acoustic field was conducted to increase the retained area of the cells by varying sweep velocity, sweep direction, and the amplitudes of sound pressure. As the result, an interferential acoustic field with a balanced sound pressures of 200 kPa-pp at a sweep velocity of 100 mm s−1, which was 10 times higher than the flow, and the sweep direction against the flow, obtained a retained area 1.6 times larger than that without sweeping. We will apply the conditions based on the results for the future 3D fabrication of artificial blood vessels.

The present study reports the chromosome number, meiotic behavior and its relation with pollen fertility and seed set of Arnebia euchroma (Royle ex Benth.) I.M.Johnst. The species shows a chromosome count of 2n = 2x = 14. The meiotic abnormalities such as chromatin stickiness, cytomixis, laggard formation, chromosomal bridges, were also observed in the Pollen Mother Cells (PMCs) of the target plant species. The linear model of regression showed a significant reduction of seed set with increasing meiotic abnormality and correlation analysis highlighted positive relationship between pollen viability and seed set. Meiotic abnormalities within the species hinder its reproductive process, causing a decline in reproductive efficiency. This study highlights the importance of addressing these intrinsic factors in future conservation programs to prevent a decline in the species population in nature.

PERFORMANCE ANALYSIS OF P&O AND PSO MPPT ALGORITHMS FOR PV SYSTEMS UNDER PARTIAL SHADING
Authors: ENDİZ Mustafa Sacid
Published: February 2024

Photovoltaic (PV) modules are devices that transform photon energy into electrical energy. The output power of the PV modules is influenced by the intensity of solar radiation and the ambient temperature. Non-uniform shading can cause variations in the extent of sunlight absorbed by PV modules, resulting in a decrease in power output. Maximum power point tracking (MPPT) techniques are employed to optimize the power output of PV modules by operating them at their maximum power point (MPP). The main objective of the study is to investigate the performance analysis of Perturb and Observe (P&O) and Particle Swarm Optimization (PSO) MPPT strategies in uniform and partially shaded conditions with equally and unequally different irradiance differences. Simulation studies were conducted on the PV circuit model using Matlab/Simulink, and the results were evaluated. MPPT algorithms are compared based on their tracking efficiency and convergence speed when solar radiation conditions vary. The findings of the simulation indicate that the P&O is unable to determine global MPP and gets trapped in one of the local MPPs. However, the PSO is very effective in tracking MPP under different partial shading patterns with more than 96% tracking efficiency. In the first partial shading configuration where the sunlight intensity of the PV modules is uniformly distributed, the PSO technique has reduced steady-state oscillations around the MPP. However, the P&O technique demonstrates superior response time and convergence speed in comparison to the PSO technique.

A correta gestão do estoque contribui para o crescimento e desenvolvimento de uma empresa, assim aumentando a competitividade e diminuindo os gastos com aquisição de mercadorias. O uso adequado de um software gerenciador de estoque, como o Enterprise Resources Planning (ERP), pode melhorar a gestão, inclusive dos estoques de uma empresa. Sendo assim, a pesquisa teve por objetivo analisar como o uso dos instrumentos de contabilidade gerencial pode auxiliar na gestão dos estoques em uma empresa do ramo de vestuário. A pesquisa é caracterizada como explicativa, estudo de caso único e qualitativa. Para a coleta de dados utilizou-se de questionários, entrevista e observação participante, possibilitando a triangulação dos dados. A partir dos resultados obtidos, elaborou-se uma matriz Strengths, Weaknesses, Opportunities e Threats (SWOT) contendo as forças, fraquezas, oportunidades e ameaças e, posteriormente, o Balanced Scorecard, com base principalmente nas oportunidades de melhorias identificadas, elencando dois objetivos estratégicos para cada uma das perspectivas: financeira, de clientes e de processos internos. Ademais, um objetivo estratégico para aprendizado e crescimento, alinhados com indicadores de desempenho mensuráveis, metas possíveis de serem alcançadas e iniciativas. Diante do exposto, conclui-se que o uso dos instrumentos de contabilidade pode auxiliar na melhor gestão de estoque na empresa analisada, contudo, para isso é preciso que os responsáveis busquem maior conhecimento sobre as ferramentas que já estão disponíveis na empresa, como é o caso do ERP e utilizam o BSC como amparo para o planejamento estratégico, visando atender as melhorias necessárias na organização.
