To account for a tail dependency structure, we introduce the Spearman copula, enabling the evaluation of Gerber-Shiu functions and ruin probabilities associated with this model. Our analysis delves into the Laplace transforms of the discounted penalty function and the probability of ruin. Towards the conclusion, explicit expressions are derived, accompanied by numerical examples illustrating ruin probabilities for individual claim sizes with exponential distributions.","PeriodicalId":502460,"journal":{"name":"Global Journal of Science Frontier Research","volume":" 38","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140392314","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}

A Python algorithm calculates prime number property sets where the sum of the elements equals the whole number values for αequal to 137 and 139. A hybrid coupling of these property sets produces a U{137/139}twin prime metaverse where α=137.036, an almost exact match to the observed value. The FSC Model projects that the Fractional Coupling Constant (α137= 0.036)is a more accurate measure of its relative electromagnetic (EM) strength. This same calculation is used to determine the Fractional Coupling Constants (αm) for the twin prime metaverses (U{2/3}, U{3/5}, U{5/7}through U{197/199}) to estimate their respective electromagnetic forces. The results suggest that this model mirrors our observable universe and offers an abstract landscape into the quantum nature of electromagnetic forces, including Baryonic Matter, Dark Matter, Dark Energy, and a possible variable speed of light.","PeriodicalId":502460,"journal":{"name":"Global Journal of Science Frontier Research","volume":"24 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140450053","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}

The duration of the study is different. During the study period in the 10th-13th experimental years, a relative equality of productivity by habitat was established, with solid and weak soil gleying, respectively, on the low or high part of the slope, especially with eastern and southeastern exposure of the mountain slope. The principle of rhythmicity in Nature (increase or decrease in productivity in even or odd years), fixed in the ancient Bulgarian calendar, finds expression in the manifestations of cultivated grasslands.","PeriodicalId":502460,"journal":{"name":"Global Journal of Science Frontier Research","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140506005","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}

When this job is performed correctly, can reduce dependence on landfill, conserve resources and protect the environment from plastic pollution and greenhouse gas emissions. Recycling is essential because almost all plastics are non-biodegradable and thus build-up in the environment, where it can cause harm. Presently, almost all recycling is performed by re-melting and reforming used plastic into new items; so-called mechanical recycling. In an alternative approach known as feedstock recycling, waste plastic is converted back into its starting chemicals, which can then be reprocessed back into fresh plastic. This whole work demonstrates the Turning Residual / Old plastics into eco-friendly alternatives, Synthetic oil, Gas or Fuel & Nanomaterials and chemical recycling as an environmental win-win situation and reinventing Recycling from rubbish to resources including live experiments/examples.","PeriodicalId":502460,"journal":{"name":"Global Journal of Science Frontier Research","volume":"82 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139312260","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}
