Domestic energy prices play an important role in energy security by controlling demand growth, and by incentivizing investments in energy resources development. In this paper, a simulation model is developed to explore how determining different prices of natural gas for various domestic demand sectors, i.e. differential pricing, affects supply security. The domestic natural gas consumption is categorized in four groups of the residential, power plants, industrial and transportation, and the dynamics between prices, supply and demand are modeled using a system dynamics model. The model is applied to a case study and various pricing policies and their influence on natural gas income and production are explored, and the minimum price growth for each sector that provides supply security is proposed.","PeriodicalId":429823,"journal":{"name":"Proceedings of the International Conference on Modern research in Engineering, Technology & Science","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125615930","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 the 20th century, it came to be known that it is important quantity in statistics and learning theory. We cannot only define it in Euclidean space, but also can expand the concept in general probability distribution. Kullback-Leibler distance is not only important as the concept, but also derive an algorithm. Kullback-Leibler distance is not only an important concept, but also it can derive the algorithm. As for the information science meaning of Kullback-Leibler distance and the relations with the mathematic properties, there exist many unknown structures. We constituted some examples about the pole using a computer algebra system and explored the properties.","PeriodicalId":429823,"journal":{"name":"Proceedings of the International Conference on Modern research in Engineering, Technology & Science","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127317649","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 healthy diet style of less dependency on synthetic colorants by replacing with the natural colorants may reduce the development of food allergies and suspicious illness of cancer development. Anthocyanin as the targeted pigment compound in butterfly pea flower was extracted by maceration method. The objectives of this research are to determine the optimum extraction conditions and to obtain the yield of the blue dye. Parameters, namely solid to liquid ratio (1:20, 1:30, 1:40, 1:50 and 1:60 g/ml), extraction time (30, 40, 60,70 and 90 min) and temperature (30, 40, 60, 70 and 90°C) were investigated by one factor at time time method (OFAT). The blue dye was characterized by gas chromatography-mass spectrometry (GC-MS) and Ultraviolet-visible spectroscopy (UV-Vis). After completing the parameters screening, design of experimental (DOE) and process optimization were utilized by response surface methodology (RSM) with central composite rotatable design (CCRD). The developed mathematical model was fit well with the experimental results for all the three manipulated variables. The optimum extraction condition of blue dye was 42.6% yield at 60 °C of extraction temperature, 1:30 g/ml solid to liquid ratio and 60 minutes of extraction time.","PeriodicalId":429823,"journal":{"name":"Proceedings of the International Conference on Modern research in Engineering, Technology & Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127574004","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}
