Supervised Learning is an important type of Machine learning. It includes regression and classification problems. In Supervised learning, Support Vector Machine (SVM) and K-Nearest Neighbors (KNN) can be used for classification and regression. Here, both algorithms are used for regression problem. The stock data is trained by SVR and KNN respectively to predict the stock price of the next day using python tool. Both algorithms are compared and it is observed that the price predicted by SVR is closer as compared to KNN.

The Gandiolais is part of the large "Niayes" ecosystem in the Saint Louis region. It is bordered by active dunes from the recent Quaternary delimiting interdune depressions in which the sub-surface water table has favored the practice of vegetable crops. These vegetable cropping areas are production systems that are now facing silting up. Our results show that this silting is due to deflation and/or mass movement of dune soils. These two phenomena are generated by the sensitivity of dune soils to deflation by trade winds and drought. The resulting negative consequences include, among others, the abandonment of vegetable cropping activities by farmers. Solutions to reduce trade wind speeds and improve the cohesion and structuring of dune soils are proposed. In particular, we recommend the creation of windbreaks and the reconstitution of sufficient plant cover.
Gandiolais是圣路易斯地区大型“Niayes”生态系统的一部分。它的边界是最近第四纪划定的丘间洼地的活动沙丘,其中的地下水位有利于蔬菜作物的种植。这些蔬菜种植区是目前面临淤积的生产系统。我们的研究结果表明,这种淤积是由于沙丘土壤的通货紧缩和/或大量移动。这两种现象的产生是由于沙丘土壤对信风和干旱的收缩敏感。由此产生的负面后果包括农民放弃蔬菜种植活动。提出了降低信风风速、改善沙丘土黏聚力和结构的解决方案。特别是,我们建议建立防风林和重建足够的植物覆盖。

In a given network there exist many paths from source to destination, among all selected paths finding the optimal shortest path is a challenging task. In this research paper, we proposed a new concept of particle swarm optimization technique, called swarm intelligence, to solve the multicast routing problem to find out the optimal route associated with a network, here we also used triangular fuzzy number tools to encode particles in PSO (particle swarm optimization), first it breaks the network into small spaces and from the small space it computes the optimal path.
在给定的网络中,从源到目的存在许多路径,在所有路径中寻找最优最短路径是一个具有挑战性的任务。在本文中,我们提出了一个新的粒子群优化技术概念,即群智能,来解决组播路由问题,从而找到与网络相关的最优路由,这里我们也使用三角模糊数工具对粒子群优化中的粒子进行编码,首先将网络分解成小空间,然后从小空间中计算出最优路径。

A novel, reversed-phase liquid chromatographic method was developed and validated for the determination of related substances in lansoprazole intermediate. Symmetric peak shape was on a C18 stationary phase with the dimensions of 250 mm column length, 4.6 mm as internal diameter, 5 microns particles with an economical and straightforward mass-compatible mobile phase combination of formic acid/triethylamine and acetonitrile delivered in gradient mode at a flow rate of 1.0 mL/min at 260 nm. The resolution between lansoprazole intermediate (LAN20) and its impurities (LAN20-I & LAN20-II) in the developed method was more than 2.0, indicating a significant separation. Regression analysis shows a correlation coefficient greater than 0.999 for lansoprazole intermediate and its related substances. The detection and quantitation limits of lansoprazole intermediate and its impurities are 0.01% and 0.005%. This method indicates that the recovery at different levels is 90 to 110% accurate. The test solution was stable in the diluent for 48 h and subjected to stress conditions. The mass balance was close to 99.5%.

WASTE-TO-ENERGY: A PROMISING MARITIME TRANSPORT TECHNOLOGY 废物转化能源:一种很有前途的海上运输技术
Pub Date : 2022-05-21 DOI: 10.29121/ijoest.v6.i3.2022.327

Everything in the world, including the shipping industry, is powered by energy. There are numerous advanced energy-generation strategies, but it would be greatly valued if energy could be consistently derived from ship waste. Waste disposal is a difficult task in the shipping industry, so many studies are being conducted to find better ways to dispose of waste. According to regulatory agencies, India has a large source of both industrial and urban organic waste. The shipping industry, like any other, necessitates massive amounts of energy. On a daily basis, a massive amount of waste is generated, ranging from small crafts to ultra-large vessels (aerobic as well as anaerobic). So, there is a significant opportunity for capturing the energy from these waste, and both the difficulty of waste disposal and the depletion of conventional energy sources can be effectively addressed concurrently. This paper examines various means of generating energy from waste. Furthermore, the current state of Waste-to-Energy (WTE) in our country and around the world is discussed.Motivation/Background: There is a perennial need for energy in all industry. This energy is pivotal in marine sector. There is huge amount of waste disposal into sea and IMO is keen on pollution control and de-carbonization. So, converting the waste serves two purposes viz. pollution control and green energy generation.Method: Various techniques for generating energy from waste had been discussed.Results: Waste-To-Energy is still a relatively unexplored technology in the shipping industry. Large cruise ships generate massive quantities of waste. This in and of itself represents a large avenue for WTE as a source of renewable energy on board ships. There are very few manufacturers venturing into the WTE segment to create power from ship waste. Scanship, a Norwegian ship waste management system manufacturer, has established a system that uses microwave-assisted pyrolysis to transform carbon-based waste generated on ships into biofuels.Conclusions: WTE is also a relatively new concept in the shipping industry. Countries such as Norway, which is successfully operating WTE plants on land, are progressively migrating the technology and paving the way for others. More initiatives like these can radically decrease the amount of waste that ships discharge into the sea, resulting in a more comprehensive ecosystem for all life forms.
世界上的一切,包括航运业,都是由能源驱动的。有许多先进的能源生产战略,但如果能够始终如一地从船舶废物中获得能源,将会非常有价值。在航运业中,废物处理是一项艰巨的任务,因此正在进行许多研究,以找到更好的处理废物的方法。根据监管机构的说法,印度有一个巨大的工业和城市有机废物来源。航运业和其他行业一样,需要大量的能源。每天都会产生大量的废物,从小型船只到超大型船只(有氧和厌氧)。因此,从这些废物中捕获能量是一个重要的机会,废物处理的困难和传统能源的枯竭可以同时有效地解决。本文探讨了利用废物发电的各种方法。在此基础上,讨论了国内外垃圾焚烧发电的现状。动机/背景:所有行业都对能源有长期的需求。这种能源在海洋领域至关重要。大量的废物被排入海洋,国际海事组织热衷于污染控制和脱碳。因此,废物转化有两个目的,即控制污染和产生绿色能源。方法:对利用废物发电的各种技术进行了探讨。结果:在航运业,废物转化为能源仍然是一项相对未开发的技术。大型游轮会产生大量的垃圾。这本身就代表了WTE作为船上可再生能源的一大途径。很少有制造商冒险进入WTE领域,从船舶废物中创造动力。挪威船舶废物管理系统制造商Scanship建立了一个系统,利用微波辅助热解将船上产生的碳基废物转化为生物燃料。结论:WTE在航运业也是一个相对较新的概念。挪威等国家已经成功地在陆地上运行了垃圾焚烧发电厂,它们正在逐步迁移这项技术,并为其他国家铺平道路。更多像这样的举措可以从根本上减少船舶排放到海洋中的废物量,从而为所有生命形式创造一个更全面的生态系统。

So, there is a significant opportunity for capturing the energy from these waste, and both the difficulty of waste disposal and the depletion of conventional energy sources can be effectively addressed concurrently. This paper examines various means of generating energy from waste. Furthermore, the current state of Waste-to-Energy (WTE) in our country and around the world is discussed.\u0000Motivation/Background: There is a perennial need for energy in all industry. This energy is pivotal in marine sector. There is huge amount of waste disposal into sea and IMO is keen on pollution control and de-carbonization. So, converting the waste serves two purposes viz. pollution control and green energy generation.\u0000Method: Various techniques for generating energy from waste had been discussed.\u0000Results: Waste-To-Energy is still a relatively unexplored technology in the shipping industry. Large cruise ships generate massive quantities of waste. This in and of itself represents a large avenue for WTE as a source of renewable energy on board ships. There are very few manufacturers venturing into the WTE segment to create power from ship waste. Scanship, a Norwegian ship waste management system manufacturer, has established a system that uses microwave-assisted pyrolysis to transform carbon-based waste generated on ships into biofuels.\u0000Conclusions: WTE is also a relatively new concept in the shipping industry. Countries such as Norway, which is successfully operating WTE plants on land, are progressively migrating the technology and paving the way for others. More initiatives like these can radically decrease the amount of waste that ships discharge into the sea, resulting in a more comprehensive ecosystem for all life forms.","PeriodicalId":331301,"journal":{"name":"International Journal of Engineering Science Technologies","volume":"63 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120990837","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}

Prediction of stock price and modelling of market pattern are quite difficult and complex to understand itself. There are hidden factors of market like effect of news, sentiment of crowd etc. which play an important role of modelling the market pattern. The modelling of market patterns was primarily developed by R.N. Elliott. The Elliott Wave theory was described subjectively in literature and wave patterns cannot be identify easily. In this work, we mainly focus on identification of wave pattern through Fractal indicators and Awesome Oscillator using R programming.
股票价格预测和市场模式建模本身就很难理解。新闻效应、群众情绪等市场隐性因素对市场格局的塑造起着重要作用。市场模式的建模主要是由艾略特提出的。艾略特波浪理论在文献中是主观描述的,波浪形态不容易识别。在这项工作中,我们主要利用R编程,通过分形指标和Awesome振荡器来识别波浪型。
