Their optimal operating temperature ranges between 15 and 45 °C. The charge mobility and chemical reaction in Li-ion batteries cause excessive heat generation leading to thermal runaway and ultimately their capacity diminishes over the life cycle. The main idea of the present study is to control the thermal runaway of the Li-ion batteries using nano-enhanced phase change materials (Ne-PCM). Hence, there is a need for the development of a battery thermal management system (BTMS) using either air, liquid, or phase change material (PCM). An 18650 battery cell (normal capacity: 2700 mAh; rated capacity: 2600 mAh; normal voltage: 3.7 V; rated power: 9.62 Wh; anode material: lithiated graphite (LiC₆); cathode material: lithium-nickel-manganese-cobalt-oxide (LiNiMnCoO₂); electrolyte material: lithium hexafluorophosphate (LiPF₆)) along with a complete battery pack (4 cells) is considered in the present study. Transient numerical simulations (using both MATLAB R2022a and ANSYS 2020 R2) are carried out with and without using the paraffin wax. Three different nanoparticles (copper oxide (CuO), aluminum oxide (Al₂O₃), and titanium oxide (TiO₂)) at various concentrations (0%, 3%, 7%, and 10%) are added to the paraffin wax to enhance their thermal conductivity value. However, the experiments are conducted only with and without using the paraffin wax, but not with the nano-enhanced paraffin wax. Hence, this (Ne-PCM case) acts only as a support to the numerical study. For both the numerical and experimental analysis, the temperature and voltage characteristics of the battery packs are measured for a specific time to understand their charging and discharging characteristics. It is found that paraffin wax is a better candidate for maintaining the battery temperature in an optimal range when the battery generates excess heat. Paraffin wax gives a 41% increase in battery life compared to air cooling. The hybrid cooling (combination of paraffin wax and air) technique reduces the battery temperature rise by 4 °C compared to only paraffin wax and by 8 °C compared to only air cooling.</p>","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"39 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141063111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, it is necessary to explore alternatives for the reuse of these wastes. Rubber has demonstrated properties that could make it an attractive material for use as a granular aggregate. The aim of this study is to evaluate the influence of crumb rubber (CR) on the mechanical behavior of a granular subbase (GSB) by replacing fine CR at 10% and 15%. An environmental analysis of the proposal was conducted using the SimaPro tool, and a series of laboratory tests were performed to assess physical and mechanical characteristics. The strength results indicate a decreasing trend as the CR content in the GSB increases. Specifically, in abrasion tests, the natural material showed an average result of 30.86%, while the mixes with 10% and 15% CR exceeded the maximum limit (50%), achieving results of 59.24% and 53.98%, respectively. In terms of the California Bearing Ratio (CBR), only the natural samples compacted at maximum energy exceeded the minimum requirements for low and medium traffic levels (30%). The highest CBR value for samples containing CR was 5%, whereas the natural GSB reached a maximum CBR of 33%. A similar trend is observed in environmental outcomes, with increases of up to 17% in abiotic depletion for the sample with 15% CR. Overall, the environmental analysis suggests that incorporating CR into the GSB could lead to an increase in various environmental impacts.</p>","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"17 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140933285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Software applications utilize bug tracking systems (BTS) to manage submitted bug reports. Recent studies showed that the majority of BRs in BTS belong to the default severity category, which does not represent their actual severity. In this paper, we propose an approach that can automatically classify default bug reports into severe or non-severe categories. We curated a dataset based on the history of bug report logs. After that, we used the Support Vector Machine algorithm and Term Frequency-Inverse Document Frequency feature extraction method to classify default bug reports into severe or non-severe categories. The results show that building customized models for default severity bug reports provides better and more reliable results than training one model for all severity. Overall, the proposed Log model outperformed the three models (approaches) from the literature; it achieved an improvement of up to ~ 4% f-measure compared to others, and in some projects, it achieved an improvement of 11.2% f-measure.

Micro-flakes are chosen due to the necessity for fewer particles to fill the gap in the machining process, resulting in reduced pollution within the gap. The assessment of the PMEDM procedure’s results is conducted based on several parameters, including the material removal rate (MRR), electrode wear ratio (EWR), average surface roughness (Ra), morphology, machined surface elemental content and recast layer. The results indicated that Gr PMEDM process offers higher machining performance in terms of MRR, EWR and the machined surface quality compared to die sink EDM process in pure dielectric. The optimum concentration was found to be 2.5 g/l Gr powder mixed dielectric for both workpiece materials. Furthermore, it was specified that the chemical composition and mechanical properties of the workpiece considerably affect the performance of die sink EDM and PMEDM. Unlike what has been discussed previously in the literature, present study revealed that formation of micro-crack and its density as well as micro-defects on the machined surface is highly dependent on workpiece elemental composition and mechanical properties.
