Depending on the constrains and the accuracy of a model, the connected equations may be more or less complicated. For simple models we may use Non Homogeneous Equations but in general, we have to deal with Homogeneous ones since from a physicists point of view nature seems to be Homogeneous. In many applications of sciences, for solving many of them, often appear equations of type n<sup>th</sup> order Linear differential equations, where the number of them is Euler-Cauchy differential equations. i.e. Euler-Cauchy differential equations often appear in analysis of computer algorithms, notably in analysis of quick sort and search trees; a number of physics and engineering applications. In this paper, the researcher aims to present the solutions of a homogeneous Euler-Cauchy differential equation from the roots of the characteristics equation related with this differential equation using MATLAB. It is hoped that this work can contribute to minimize the lag in teaching and learning of this important Ordinary Differential Equation.</p> S.

As the voltage increases from 0.0 V to 55.0 V DC voltage, the removal efficiency increases up to 98% with the time limit of 35 seconds at a normal pH value of 7.0 - 7.85. As the temperature increases from room temperature to 75<sup> 0</sup>C, the coagulation increases and even the number of pairs of electrodes plays an important role in coagulation. The obtained sludge is characterized to identify its composition.</p> S. Mohan, B. M. Nagabhushana, Chikkahanumantharayappa, C.

The semantic web vision advances an everyday growing of the semantic diagram that requires some preparing upgrades including SPARQL end-point and combined questions to secure the interminable extension. The current progressed elite figuring engineering has been growing quickly to conquer numerous issues including execution. Elite registering can possibly be utilized to improve the unified SPARQL inquiry and generally speaking activity including the performance and handling. Hence, this work surveys the procedures to advance the improvement on isolated and distant combined semantic-based information. That is, the superior figuring climate including equipment engineering and extraordinary design registering has been overviewed. Besides, working semantic diagram combination necessities is dissected. Besides, the current strategies to demonstrate SPARQL execution are considered. Furthermore, an examination about the usage of cutting edge equipment figuring engineering is investigated to upgrade the execution of the current SPARQL alliance administration activity.</p> S. Ravichandran Copyright (c) 2021 Sat, 15 May 2021 00:00:00 +0530 Agricultural Regionalization: Spatial Analysis of Crop Combination Regions <p>Crop combination regions refer to the number or diversity of crops grown in a particular area during a specific interval of time [1]. These regions provide strong basis for agricultural regionalization. Developmental policies and other planning measures can be taken on the basis of these regions. This research paper is a case study and it is based on Land Record Circles. The method used for delineation of regions is Rafiullah’s maximum positive deviation method. Out of 11 LRC’s 10 are mono crop regions and the prominent crop is Bajra. The results of the paper are analyzed according to the climatic conditions of the study area. This is a semi-arid region and major part of it is a dark zone. So, the rain fed agriculture is done in the study area. The Bajra crop is produced on south west-monsoon.</p> Shivraj Meena Copyright (c) 2021 Sat, 15 May 2021 00:00:00 +0530 The Impact of Emerging Technologies on Data Mining <p>Business analytics has improved tremendously in recent past providing business leaders’ insights, particularly from operational data stored in transactional system. An example is e-commerce data analysis, which has recently come to be viewed as a killer appropriate for the field of data mining.</p> Atkinson Ike Madukwe, Jennifer Somtochukwu Madukwe, Justina Ogochukwu Osonwa, Obiora Chukwuemerie Ernest Copyright (c) 2021 Sat, 15 May 2021 00:00:00 +0530 Impact of Corona Virus on African Economic Growth <p>The COVID-19 crisis is affecting the entire world economy and that of Africa. Some key sectors of the African economy are already experiencing a slowdown because of the pandemic. Tourism, air transport, and the oil sector are visibly impacted. The exogenous effects come from direct trade links between affected partner continents such as Asia, Europe and the United States; tourism; the decline in remittances from African Diaspora; Foreign Direct Investment and Official Development Assistance; illicit financing flows and domestic financial market tightening, etc. The endogenous effects occur because of the rapid spread of the virus in many African countries. On one hand, they are linked to morbidity and mortality. On the other hand, they lead to a disruption of economic activities. This may cause, a decrease in domestic demand in tax revenue due to the loss of oil and commodity prices coupled with an increase in public expenditure to safeguard human health and support economic activities. This study aims to evaluate the potential impact of the pandemic on various dimensions of African economies, the impact on the African economy is presented, with a discussion of some of the key measures being taken by African Union to mitigate the negative effects.</p> Abeer Mohamed Abdel Razek Youssef Copyright (c) 2021 Sat, 15 May 2021 00:00:00 +0530 The Educational Impact of Adopting Electronic Notes Pre Covid-19 <p>This paper seeks to understand the educational impact of using Electronic Notes (e-notes) with undergraduate students at a South African University. The majority of research studies done in this area indicate that students prefer printed notes to e-notes. This study seeks to investigate if the same trends hold true for the selected group of students, who transitioned from the regular printed notes to e-notes prior to the COVID-19 pandemic. A questionnaire was developed to gather students’ perceptions on e-learning material, specifically e-notes, and its impact on their learning experience. The population included students within the Computer Science and Information Systems and Technology faculties of the selected institution. The quantitative research method was adopted and data was analysed using SPSS. The areas of effort expectancy, performance expectancy, social influence, facilitating conditions, and self-efficacy associated with e-note usage were investigated. The findings indicate that some of the positive trends observed in the literature review hold true for this group of students and that the use and implementation of e-notes primarily have a positive impact on these students.</p> Upasana Gitanjali Singh Copyright (c) 2021 Sat, 15 May 2021 00:00:00 +0530 Association Rules Based Opinion Mining for E-Learning and Electronic Literature Reading <p>The revolution in Information technology has transformed our academics and projected it in the new dimension. ICT supported learning is best facilitating learners’ needs. With some pros there are some cons as well which are affiliated with e-learning. This study is analyzing the opinions of respondents towards e-learning and electronic literature reading. To analyze the response authors employed Apriori algorithm of association rule mining approach. The support and confidence values or the analysis were kept high (≥85) to achieve good quality of association among such factors. Study finds stress generated while adopting e-learning and e-reading has higher association with content availability in web resources. This very inferable that the wide content range results more surfing and searching and resulting stress. Study also found that the distractions caused by resource divergence are strongly associated with stress and problems faced in eyes. The study is giving significant contribution towards policy making and analysis of factors that affects the learners’ choices and problems the most.</p> Shubham Dubey, Ispany Marton Copyright (c) 2021 Asian Journal of Science and Applied Technology Sat, 15 May 2021 00:00:00 +0530
