In addition, the energy equation contains terms for radiational heat flow, heat injection, and suction. The perturbation approach provides an analytical solution to the governing nonlinear partial differential equations underlying this phenomenon. The numerical approach in the Maple program was used to verify the correctness of the outcomes produced by the perturbation technique. The Grashof and Prandtl numbers, Casson fluid, magnetic field, and porosity parameters as well as radiation parameter, and heat injection/suction parameter impact on the flow is discussed graphically. Skin friction coefficient and Nusselt number are tabulated for a range of magnetic and radiative parameter values. The other physical factors listed above accelerate the fluid velocity, but the magnetic field decreases it. Furthermore, the wall shear stress and heat transfer were significantly impacted by the magnetic and radiative factors.","PeriodicalId":167914,"journal":{"name":"Journal of Applied Science, Information and Computing","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139360913","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}

This study was aimed at determining the impact of big data analysis in telecommunication industry and also to arouse their interest towards big data. The study used four domestic telecommunication companies as case study, namely MTN, GLO, 9Mobile and AIRTEL. The study uses survey method of data collection by using structured questionnaire. Sixteen network nodes were used in the study from four clusters. Analysis of Variance (ANOVA), Cronbach’s Alpha Coefficient using Smart – PLS, DBSCAN Algorithm was employed using google python as data analysis method. The study revealed that there is high traffic data from the telecoms and this is as a result of various user activities like internet usage and highly dense network clusters, which happened at a specific time or within a particular duration at a specified location. The findings led to a conclusion that the big data analytics can be considered as a solution to directional small cells in millimeter wave cellular networks to improve QoS. The study recommends that big data should be given due consideration and be used in making national budget and policy formulation. The study further recommends that tertiary institutions should create big data analytics training to create a platform for training and development of manpower mainly on big data analytics as is obtainable in developing and IT-driven countries.","PeriodicalId":167914,"journal":{"name":"Journal of Applied Science, Information and Computing","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121909353","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}

For live childbirths, birthweight should preferably be measured within the first hour of life, before substantial post-natal weight loss has occurred. Low birth weight renders children exposed to infectious disease morbidity and mortality during both infancy and childhood. The objective of the study was to apply the modified binary logistic model to determine the factors associated with low birth weight among children in Uganda. The data used for this study was the Uganda Demographic and Health Survey (UDHS- 2016), the UDH survey selected 20615 households where 15522 women were successfully interviewed with known child birth weight out of which 5498 observations were considered after data cleaning. The results of the study revealed that the association between the age of the mother and low birth was statistically significant with a p-value of 0.044. The study also found that the risk of low birth weight babies was low for married women as compared to non-married women with a p-value of 0.003. Antenatal visit during pregnancy decreases the chances of having an infant with low birth weight. The association between low birth weight and the employed was statistically significant with a p-value of 0.007 and the likelihood of low birth weight infants for the rich was low as compared to the poor. The study concluded that the association between age, antenatal visits during pregnancy, occupation, wealth status of the mother and low birth weight were statistically significant.","PeriodicalId":167914,"journal":{"name":"Journal of Applied Science, Information and Computing","volume":"286 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123727884","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 Hadamard products of two functions have one thing in common that is, it involves the origin. Irrespective of the factors of the Hadamard product either power series or holomorphic functions, the open sets on which they are examined contain the origin. The aim of this study, therefore, is to investigate on the properties of Hadamard product for a class of holomorphic functions with an arbitrary fixed point. The concept of Hadamard product, Cauchy-Schwartz, holomorphic functions, Ruscheweyh differential operators, and Nevanlinna’s theorem are employed in this study. This study generalized the coefficient inequalities for starlike and convex functions of exponential order  with an arbitrary fixed point using Ruscheweyh derivative. This study further provides an additional inequality and Hadamard product for a class of holomorphic functions with an arbitrary fixed point. It is concluded that Ruscheweyh derivative is an effective tool in the generalization of Hadamard product for a class of holomorphic functions with an arbitrary fixed point.","PeriodicalId":167914,"journal":{"name":"Journal of Applied Science, Information and Computing","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132320378","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 technology is expected to provide faster speed, greater reliability, low latency, in addition to opening up a new sphere of possibilities such as connected vehicles and devices. However, despite the expectation of improvements promised in the 5G era when compared to previous mobile wireless technologies such as 4G and 3G, there is a growing concern within the ICT industry that there are a number of security issues, particularly cybercrime attacks that may likely become rampant due to the power of the 5G technology. ICT experts agrees that 5G technology will result in massive data transactions due to the ultra-high speed, low latency and extra capacity provided by these networks. Therefore, there is the need to ensure that data and transactions are secured in such a way that personal information is not hacked, data privacy is preserved, and systems do not crash. Objective: The objective of this study is to analyze the critical challenges in combating cybercrime activities in the era of 5G technology. The paper will look at the security issues in the 4G networks and then compare it with the upcoming technologies expected in the 5G era. Method: The paper uses secondary data that was obtained by reviewing relevant articles written by various scholars on the topics of 5G technology, 4G technology, cybercrime activities in the era of 4G, how cybercrime will be tackled in the era of 5G technology, as well as evolution of mobile generation technologies from 1G to 5G.

World Health Organization (WHO) also confirmed this assertion and as a result, there have been series of attempts by researchers in various fields to solve this problem. Certain researchers in computer and health informatics carried out predictive analytics to detect and classify the disease based on several biomarkers identified in the affected individual. Meanwhile, enough has not been done to determine the level of susceptibility of individuals to heart diseases with concerted effort on the key indicators such as age, sex, sugar level and some other related attributes before predictive analytics are made. This explores the attribute and it was finally established that sex, age, level of cholesterol etc. are strong markers to determining the level of susceptible of patient to heart disease. Moreover, Four ML models - KNN, NB, SVM and RF were implemented and evaluated in term of their performances in the classification of heart diseases using crossvalidation and test dataset. At first, with every feature available in the dataset and later with only the correlated features identified in the descriptive analytics. It was established that accuracy improves across all models when only correlated features were used and SVM exhibits the highest accuracy and F1 Score (84%). Therefore, SVM performs better than KNN, RF and NB when all the models were evaluated on the 25% test set of the correlated features. It could be therefore concluded that in-depth understanding of features for identification of strong disease biomarkers will enhance more accurate diagnostics and this in turn will be of great assistance to the medical practitioners and other stake holders to track susceptibility of individuals with identified features to heart disease.","PeriodicalId":167914,"journal":{"name":"Journal of Applied Science, Information and Computing","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115330967","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}
