Comparison of Microphysics Schemes on WRF-HAILCAST Model to Study Hailstone in Aeronautics (Case Study: Hail Strike on AirAsia A320-200, November 16, 2018)
Authors: Maulana Muhammad Ikko Safrilda , Kristianto Aries 
Published: July 2024

A hail strike is caused by the hail phenomenon, an aviation accident caused by environmental factors. Hail is a type of extreme weather in the form of precipitation ice grains which is generally caused by cumulonimbus clouds. Research on hail modeling can be carried out using the Weather Research Forecasting Hail Forecast (WRF-HAILCAST), which can model the structure, dynamics, microphysics, hailstone distribution, and estimate the maximum diameter of the hailstone. In this study, the hail modeling that caused the hail strike on the AirAsia A320-200 aircraft on November 16, 2018, was carried out using the WRF-HAILCAST model with six different microphysics schemes. This study compares the results of the microphysics scheme on the WRF-HAILCAST model in hail modeling. The results of this study indicated that each microphysics scheme produces a different outcome. Generally, the spatial and temporal distribution of the entire scheme could indicate the presence of convective clouds reaching 40–55 dBZ. Each scheme showed the microphysical processes of clouds consisting of different hydrometeor particles. However, only MY2 and NSSL showed the presence of supercooled water, and those schemes could estimate maximum diameter hailstone worth 25.8 mm and 13.2 mm. So, NSSL is the best microphysics scheme in this study.DOI: 10.17977/um024v8i12023p020

Published: July 2024

Abstract: Linguistic features are intended to be investigated in some literary works as carried out in the current study. This study conducted a stylo-pragmatic investigation of linguistic characteristics in the debut work of Nadia Hashimi, The Pearl that Broke Its Shell. The primary objective of this research is to focus on the pragmatic analysis of the chosen speech acts in various contexts, in addition to exploring the stylistic techniques utilized in those specific texts. Pragmatics elucidates that the utilization of language in unconventional manners is deemed permissible, on the condition that language users possess an understanding of their actions. Linguistic stylistics delves into the linguistic characteristics of a given text, focusing predominantly on the utilization of language and its impact on said text. Hence this paper investigates the selected contexts in the mentioned novel by Hashimi where the texts are analyzed pragmatically besides the stylistics investigation. The study spots light on the enriched style of Nadia Hashimi in the novel “The Pearl That Broke Its Shell”.
Text Stemming and Lemmatization of Regional Languages in Indonesia: A Systematic Literature Review
Authors: Abidin Zaenal , Junaidi Akmal , Wamiliana  
Published: July 2024

Background: Stemming is significantly essential in natural language processing (NLP) due to the ability to minimize word variations to fundamental forms. This procedure facilitates the analysis of textual data and enhances the precision of classification and information retrieval.
Objective: Previous related systematic literature review has not been conducted on stemming and lemmatization in regional languages in Indonesia. Therefore, this study aims to conduct a systematic literature review to capture the latest developments in stemming and lemmatization in regional languages in Indonesia.
Methods: This study was carried out using Kitchenham method, analyzing 35 studies extracted from 740, which were obtained from Scopus, IEEE Xplore, and Google Scholar, and published between 2014 and 2023.
Results: The results showed that study trends in stemming possessed the potential to continue developing every year. Additionally, the main element in stemming and lemmatization studies was found to be the availability of digital dictionaries in regional languages. This was because greater number of basic vocabularies contributed more positively to stemming or lemmatization. The availability of word morphology information in regional languages would be constructive for making rule-based stemmers. Meanwhile, corpus-based stemming and lemmatization studies could only be conducted for languages with a large corpus to ensure there were various affixed words to process.
Conclusion: Based on SLR study, stemming and lemmatization in regional languages in Indonesia developed significantly from 2014 to 2023. The two main strategies applied included using available digital dictionaries and language morphology information. However, the main challenges encountered were the limited number of vocabulary words in the dictionaries and testing various rule-based methods.

A Matched Comparison of Implant and Functional Outcomes of Cemented and Cementless Unicompartmental Knee Replacements
Authors: Mohammad Hasan R. , Judge Andrew , Murray David W. 
Published: July 2024

Background:
Unicompartmental knee replacement (UKR) is an effective treatment for end-stage medial compartment osteoarthritis, but there can be problems with fixation. The cementless UKR was introduced to address this issue. It is unknown how its functional outcomes compare with those of the cemented version on a national scale. We performed a matched comparison of the clinical and functional outcomes of cementless and cemented UKRs.

Methods:
Using the National Joint Registry for England, Wales, Northern Ireland and the Isle of Man (NJR), 14,764 Oxford UKRs with linked data regarding patient-reported outcomes were identified. A total of 6,906 UKRs (3,453 cemented and 3,453 cementless) were propensity score matched on the basis of patient, surgical, and implant factors.

Results:
The 10-year cumulative implant survival rate was 93.0% (95% confidence interval [CI], 90.0% to 95.1%) for cementless UKRs and 91.3% (95% CI, 89.0% to 93.0%) for cemented UKRs. The cementless UKR group had a significantly lower revision risk (hazard ratio [HR], 0.74; p = 0.02). Subgroup analyses showed a stronger effect size (HR, 0.66) among UKRs performed by high-caseload surgeons (i.e., surgeons performing ≥30 UKRs/year). In the overall cohort, the postoperative Oxford Knee Score (OKS) in the cementless group (mean and standard deviation, 39.1 ± 8.7) was significantly higher (p = 0.001) than that in the cemented group (38.5 ± 8.6). The cementless group gained a mean of 17.6 ± 9.3 points in the OKS postoperatively and the cemented group gained 16.5 ± 9.6 points, with a difference of 1.1 points between the groups (p < 0.001). The difference in OKS points gained postoperatively was highest among UKRs performed by high-caseload surgeons, with the cementless group gaining 1.8 points more (p < 0.001) than the cemented group.

Conclusions:
The cementless UKR demonstrated better 10-year implant survival and postoperative functional outcomes than the cemented UKR. The difference was largest among UKRs performed by high-caseload surgeons, with the cementless fixation group having an HR for revision of 0.66 and an approximately 2-point greater improvement in the OKS compared with the cemented fixation group.

A Fractal Model of Fracture Permeability Considering Morphology and Spatial Distribution
Authors: Zong Peng , Xu Hao , Tang Dazhen , Chen Zhenhong , Huo Feiyu 
Published: July 2024

Summary
In fractured reservoirs, the fracture system is considered to be the main channel for fluid flow. To better investigate the impacts of fracture morphology (tortuosity and roughness) and spatial distribution on the flow capacity, a fractal model of fracture permeability was developed. Based on micro-computed tomography (CT) images, the 3D structure of the fracture was reconstructed, and the fractal characteristics were systematically analyzed. Finally, the control of permeability by fracture morphology and spatial distribution in different fractured reservoirs was identified. The results demonstrate that the complexity of the fracture distribution in 2D slices can represent the nature of the fracture distribution in 3D space. The permeability fractal prediction model was developed based on porosity (φ), spatial distribution fractal dimension (Df), tortuosity fractal dimension (DT), and opening fractal dimension of the maximum width fracture (Db). The permeability prediction results of the fractal model for Samples L-01 (limestone), BD-01 (coal), BD-02 (coal), S-01 (sandstone), M-01 (mudstone), and C-01 (coal) are 0.011 md, 0.239 md, 0.134 md, 0.119 md, 1.429 md, and 27.444 md, respectively. For different types of rocks, the results predicted by the model show good agreement with numerical simulations (with an average relative error of 2.51%). The factors controlling the permeability of fractured reservoirs were analyzed through the application of the mathematical model. The permeability is positively exponentially correlated with the fractal dimension of spatial distribution and negatively exponentially correlated with the fractal dimension of morphology. When Df &lt; 2.25, the fracture spatial structure is simple, and the morphology and spatial distribution jointly control the seepage capacity of fractured reservoirs. When Df &gt; 2.25, the fracture spatial structure is complex, and the impact of morphology on seepage capacity can be disregarded. This work can effectively lay the foundation for the study of fluid permeability in fractured reservoirs by investigating the effects of fracture morphology (tortuosity and roughness) and spatial distribution on flow capacity.

Published: July 2024

Summary
To improve the penetration performance of polycrystalline diamond compact (PDC) bits in hard-to-penetrate plastic formations, the study of three-ribbed ridge nonplanar PDC cutter technology was carried out. The rock-breaking characteristics of nonplanar cutters are analyzed by comparison with conventional planar cutters and axe-shaped cutters through simulation and indoor experiments. The simulation results show that the planar cutter mainly breaks the rock by shearing and extruding, the axe-shaped cutter mainly breaks the rock by shearing, and the nonplanar PDC cutter mainly relies on its convex ridge structure to penetrate and split the rock. Nonplanar cutter has better penetration performance and cutting stability than planar cutters and axe-shaped cutters. The field test shows that the rate of penetration (ROP) and footage of the developed PDC bit with three-ribbed ridge nonplanar PDC cutters are increased by 133.66% and 176.11% compared with the conventional PDC bit in the hard-to-penetrate plastic formations. The use of nonplanar PDC cutters improves the working stability, rock-breaking efficiency, and service life of the bit. The special three-ribbed ridge structure of the nonplanar cutter has changed the interaction mode between the cutter and the rock. Its successful application in the plastic formation provides a reference for faster drilling of PDC bits in hard-to-penetrate plastic formations.

Published: July 2024

Abstract

This study was designed to investigate the sustainability of using biomass as fuel for industrial boilers within the manufacturing sector, with particular reference to Cargill Ghana Limited, located within the Free zones enclave of Tema. The research was designed to achieve four specific objectives including; The identification of the social-economic benefits of using biomass as boiler fuel; Examination of the potential environmental impact of biomass as boiler fuel; Determination of the impact of fossil fuel cost on the adoption of biomass as boiler fuel; and Identification of the challenges which hinder sustainability in the adoption of biomass as boiler fuel. Adopting a convenient sampling model, a sample size of 65 was evaluated from Cargill’s population of 187 using sample calculator. The primary data was collected with the aid of interviews and questionnaires administered on suppliers and staff respectively. The acquired data was analysed with tables, pie charts, histograms and mathematical interpretations for the demographics, and tables along with central tendencies of frequencies for the main survey. The findings reveal that an average of 74.1% of the participants agree that biomass as a boiler fuel has some socio-economic benefits. While majority of the participants remained neutral, only 28.6% indicated that the adoption of biomass has environmental consequences. The findings further show that 73.1% of the people agree that the continuous increases in the prices of fossil fuel have triggered high adoption of biomass. Lastly, 54.2% of the participants believe that climatic factors such as, land allocation and land tenure; occupational accidents and illness; deforestation and land degradation; and the level of wood harvest directly affect sustainability of the production and use of biomass. In view of the findings, the research proposed some recommendations to ensure sustainability in biomass fuel. Notable among these is the use of highly efficient boilers to cut down emissions, and the investigation of factors affecting sustainability and finding solutions to them. When the recommendations are effectively implemented, the study would immensely benefit Cargill and the policy makers.

Abstract

The reliance of outdoor exposure data in epidemiological studies on temperature entails important uncertainties from personal exposure misclassification. We analysed ~88,000 concurrent person-hours of measured personal, household (kitchen and living room), and outdoor temperatures collected in the summer (MAY-SEP 2017) and winter (NOV 2017-JAN 2018) in rural and urban China. The temperatures across microenvironments were strongly correlated (Spearman’s ρ: 0.86-0.92) in summer. In winter, personal temperature was strongly related to household temperatures (ρ: 0.74-0.79) but poorly related to outdoor temperature (ρ: 0.30). Random forest (RF) algorithm identified household and outdoor temperatures and study date as top predictors of personal temperature exposure for both seasons, and heating-related factors were important in winter. Multivariable linear regression and RF models incorporating questionnaire and device data performed satisfactorily in predicting personal exposure in both seasons (R2summer: 0.92; R2winter: 0.68-0.70). Using generalised additive mixed effect models, we found consistent U-shaped associations between measured and predicted personal temperature exposures and heart rate (lowest at ~14.5ºC), but a weak positive linear association with outdoor temperature. Personal and outdoor temperatures differ substantially in winter, but prediction models incorporating household and outdoor temperatures and questionnaire data performed satisfactorily. Exposure misclassification from using outdoor temperature may produce inappropriate epidemiological findings.

Published: July 2024

Abstract

Room-temperature chemiresistive sensors are valued for their low power consumption, ease of operation, and real-time monitoring capabilities, making them highly advantageous for various applications. However, the challenge of inaccurate detection due to variations in operating temperature is a significant hurdle for their practical use. To address this, we developed a ratiometric-gas sensing method that leverages the exceptional photoelectric and chemiresistive gas sensing sensitivity of organic-inorganic hybrid superlattice materials AgBDT. This approach can effectively detect NO2 molecules, with a detection limit of 3.06 ppb. Crucially, the ratiometric-gas sensing technique offers robust diminution to temperature interference, with the CV value dropping from 21.81–7.81% within the temperature range of 25 to 65°C, which significantly enhances the stability and reliability of the device. This method would be capable of not only the detecting of gases but also providing rapid, accurate analysis in real conditions through temperature-compensated ratiometric-gas sensing technique.
