Power stations must\u0000hold carbon credits and follow tight carbon emission restrictions. This is crucial for minimizing global warming and\u0000sustaining life. Electric power system planning and operation must meet load demand reliably, cost-effectively, and\u0000environmentally. Planners and operators use optimisation tools to attain these goals. In this study, the performance of two\u0000new optimisation methods, like the Whale Optimisation Algorithm (WOA), is compared to the performance of two older\u0000optimisation methods, like the Moth Flame Optimisation (MFO) and the Ant Lion Optimisation (ALO). When compared to\u0000the other two optimisation method, the results from the new optimisation method are better. It is obvious that there are\u0000competing goals that must be met. One cannot reasonably expect to achieve both the goal of reducing fuel costs and that of\u0000reducing gaseous emissions. In order to aid decision-makers in making the best choices, multi objective optimisation\u0000techniques are used to derive trade-off relationships between these incompatible goal functions. In this study, we examine\u0000the economic load dispatching issues that arise in the operation of power systems. The objective function of the issue is\u0000first analysed as a multi-objective function, with power dispatch and environmental considerations each being addressed as\u0000a distinct goal. Both the single- and multi-objective variants are examples of high-dimensional, nonlinear, non-convex\u0000constrained optimisation problems. Because of this, employing any optimisation strategy is extremely difficult. Several\u0000algorithms, including those that take their cues from nature, have been implemented to help us get as near as possible to\u0000optimum solutions tools.","PeriodicalId":38652,"journal":{"name":"ARPN Journal of Engineering and Applied Sciences","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140414472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sound concerns arise\u0000from the side effects of replacing normal aggregate with tire rubber waste, which is expected to affect mechanical\u0000properties of the Portland Cement Concrete (PCC) mixes. To be able to decide on suitable Tire Derived Aggregates (TDA)\u0000replacement percentages, a simplified model is proposed to predict the PCC mixes stress-strain diagram with different\u0000TDA percentages. 0, 10, 20, 40, 60, 80 and 100% TDA were investigated. Using homogenization and lab test results for\u0000PCC mixes, 0% and 100% TDA were used as upper and lower bounds, and a model was developed to predict Young’s\u0000moduli and stress-strain curves for evaluated PCC mixes. Then the model results were verified using other test results. It\u0000was found that the proposed model seems to capture the behaviour of PCC mixes with TDA fairly well. However, peak\u0000stress for PCC mixes with 40% TDA results were slightly underestimated, but with reasonable accuracy. Furthermore, the\u0000proposed model well predicted the ultimate stresses, ultimate strains, and the elastic modulus.","PeriodicalId":38652,"journal":{"name":"ARPN Journal of Engineering and Applied Sciences","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140414862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several soil improvement methods are available to address these issues. One viable approach to enhancing soil quality is through lime and cement stabilization. This research aims to investigate the impact of a lime and cement mixture on the physical and mechanical properties of the soil at the research location. The research results reveal that the CBR (California Bearing Ratio) value for the original soil is 5.60%. CBR values increased in specific mixture variations, with the CBR value for the original soil + 3% lime + 5% cement mixture reaching 11.56%. This mixture can be employed in the subgrade, meeting the CBR requirement for road construction subgrade, which is 6%. In the case of the mixture involving the original soil + 10% lime + 10% cement, a CBR value of 26.50% was achieved. The CBR value for subgrade with outstanding criteria for road construction is 20% to 30%. The addition of a lime and cement mixture for peat soil stabilization can significantly enhance the soil's bearing capacity, and increasing the percentage of lime and cement in the mixture leads to higher CBR values.","PeriodicalId":38652,"journal":{"name":"ARPN Journal of Engineering and Applied Sciences","volume":" 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139786861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

WAF and WMF to improve the performance of average and median filters 用 WAF 和 WMF 提高平均值和中值滤波器的性能

{"title":"WAF and WMF to improve the performance of average and median filters","authors":"","doi":"10.59018/1223309","DOIUrl":"https://doi.org/10.59018/1223309","url":null,"abstract":"Salt and spice noise is considered one of the most common types of noise that affect grayscale and color digital images, as it affects them negatively, and this negative effect increases with an increase in the noise ratio. Many digital filters are used to mitigate the negative effects of salt and pepper noise, and the most widely used of these filters are the average filter and the median filter. The average and median filters work on processing all pixels in the image, whether these pixels are intact from the noise or infected with it, and accordingly, mitigating this noise, especially if it has a high noise ratio, is ineffective. In this research paper, new window average and window median filters will be proposed to enhance the performance of standard average and median filters. The proposed filter will treat the infected pixels, leaving the clean pixels as they were. For a noisy pixel, a special window will be created and the pixel value will equal the mean (or average) of the cleaned pixels in the window (excluding the noisy pixels). To simplify the window processing an index window will be used, this window will point to the noisy and cleaned pixels in the selected pixel window. Several images with various values of noise ratios will be tested; several windows with different sizes will be examined to get the most suitable window size. The selected window size will be used to filter various noisy images, the obtained results will be compared with average and median filter results to show the improvements provided by the proposed method.","PeriodicalId":38652,"journal":{"name":"ARPN Journal of Engineering and Applied Sciences","volume":"12 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139786562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper's research, a simplified method of speech file cryptography will be provided, and the encryption and decryption functions will require a reduced number of operations. The encryption function will perform a put_operation to reorder the speech sample to get the encrypted file, while the decryption function will perform a get_operation to reorder the encrypted samples to get the decrypted speech file; these operations will be implemented based on the generated secret indices key. The Put and get operations will affect the speech file by recording the samples keeping the histograms of the speech files (source, encrypted, and decrypted) the same and without any changes. The secret key generation phase will be analyzed for efficiency purposes, and two methods will be presented: The first one will use the chaotic logistic map model to generate the secret indices key, while the second method will use a selected secret image to generate the secret indices key, both methods will be tested and examined to give some recommendations for the users. Each of the introduced methods will provide a high level of security, the private keys will provide a huge key space and they will be very sensitive to resist any hacking attacks. The quality, sensitivity, security, and speed of the proposed methods will be examined, the method will be tested and implemented, and the obtained results will be analyzed to prove the achievements provided by the proposed method.","PeriodicalId":38652,"journal":{"name":"ARPN Journal of Engineering and Applied Sciences","volume":"125 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139786157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two distinct degradation stages are observed in CSR-PS blends, mirroring pure CSR samples: the initial phase (200-400°C) decomposes biomass components, while the second stage (400-550°C) targets the synthetic polymer PS within CSR-PS blends. Analyzing thermal degradation parameters reveals insights. 100% PS exhibits the highest weight loss and activation energy, highlighting PS's formidable decomposition. Conversely, 100% CSR shows the lowest weight loss and activation energy due to its organic composition. Artificial Neural Network (ANN) modeling indicates varying correlation accuracies for different blend compositions. Surprisingly, 100% PS exhibits lower correlation accuracy in predicting weight loss compared to the 80% PS blend, which achieves a perfect correlation. Conversely, 100% CSR, with simpler decomposition, has the lowest correlation accuracy. These findings illuminate the complex thermal behavior of CSR-PS blends, emphasizing the distinct degradation characteristics of PS and CSR. Implications extend to material applications and disposal strategies, emphasizing tailored approaches based on blend compositions and thermal profiles. This research advances co-pyrolysis as a sustainable avenue for liquid fuel production, providing insights for future research and practical applications.","PeriodicalId":38652,"journal":{"name":"ARPN Journal of Engineering and Applied Sciences","volume":" June","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139787318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
