Perturbation-oriented numerical research has been carried out in the current study to characterise the properties of velocity and axial pressure gradient in an inclined channel under Hall effect on the peristaltic flow of a Hyperbolic tangent because of these real-world applications. Under low Reynolds number and long-wavelength approximations, the current physical model yields the governing two-dimensional coupled nonlinear flow equations. For different values of the physical parameters, a suitable equation for the stream function is derived, and a regular perturbation scheme is used to produce the numerical solutions in terms of pressure rise and velocity. Weissenberg number, power-law index, Hall parameter, Hartmann number, and amplitude ratio relationships are examined in graphs along with their effects on the axial pressure gradient and time-averaged volume flow rate. According to the findings of this study, whereas the axial pressure gradient and time-averaged flow rate in the pumping region enhance with rising values of the Weissenberg, Hartmann, Reynolds, angle of inclination, and amplitude ratio, they diminish with enhances in the power-law index, Hall parameter, and Froude number. Hyperbolic tangent fluid has been discovered to require less pumping than Newtonian fluid.","PeriodicalId":281529,"journal":{"name":"Asian Research Journal of Mathematics","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117028219","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}

Monthly time series data from January 2006 to December 2022 is used. Six endogenous variables namely; US dollar exchange rate, broad money supply, total import, 20 Nairobi stock exchange share index, consumer price index and 91 days treasury bond rate sourced from the central bank of Kenya were considered. Global food price index and oil prices per barrel sourced from statista and Murban Adnoc respectively are the exogenous variables. Unit root test is first performed to test for stationary in line with VAR assumptions. Oil price and total import are the only stationary variables, while the other variables are of integrated order 1. Secondly, a VARX (2,0) is estimated, which is statistically significant at 5% level. Thirdly, Granger causality test is performed, that provide evidence of causality for 20 Nairobi stock exchange share index, consumer price index and broad money supply with respect to other endogenous variables. In addition, VARX(2,0) is converted to MA(2) to develop US dollars impulse response function. There exist high level of volatility for all variables. Finally, a forecast error variance decomposition following Cholesky decomposition shows significant proportion of variance explained by other variables respectively. Kenya’s policy makers need to build strong framework for monetary policy and exchange rate control measures in safeguarding the performance of macroeconomic indicators.","PeriodicalId":281529,"journal":{"name":"Asian Research Journal of Mathematics","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133262882","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 this interaction, plants are the primary food source for herbivores while natural enemies of herbivores depends on herbivores for food and on plants for shelter. Harvesting of every species which is common in many habitat may affect the population densities of the species and even the entire ecosystem. Therefore, conservation and maintenance of the harvested species is critical for ecosystem balance. In this paper, a model of plant-herbivore-natural enemies interactions with the constant effort harvesting of every species was developed and analyzed. The positive invariant set, the conditions of existence and locally asymptotically, stability of the equilibria were determined using the stability theory of ordinary differential equations. The results shows that the species being harvested would become extinct if harvesting effort exceeded a threshold value for the given population. While maintaining the coexistence of populations in the ecosystem requires sensible harvesting practices. Therefore, it is fair to choose a reasonable harvesting effort to allow all species to coexist in order to govern the species’ dynamic behavior. The insights of the solutions of this study are of great essence to ecologists and policy developers in environmental conservation. The authorities to pay attention to the minimum number required based on the area coverage in deciding when to harvest and also be cautious to the amount and effort of harvesting in view of conserving the species and the environment.","PeriodicalId":281529,"journal":{"name":"Asian Research Journal of Mathematics","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128679209","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}

By establishing an explicit formula for the entries of the inverse of generalized Vandermonde matrices, a fresh perspective on these mathematical challenges is introduced. The study primarily focuses on linear recurrence relations and thoroughly investigates cases involving characteristic polynomials with both simple roots and roots of multiplicity. To illustrate the effectiveness and practicality of the proposed method, a comprehensive set of illustrative examples is provided, highlighting its applicability in solving a wide range of instances of linear recurrence relations. Additionally, the limitations of the formula are discussed, particularly in scenarios where its applicability may be restricted. The findings of this study contribute significantly to the existing literature, providing an alternative and promising approach for solving problems that rely on the inverse Vandermonde matrix. In conclusion, this article emphasizes the need for further research to explore the computational advantages of the proposed method and to extend its applicability to cases featuring characteristic polynomials with a single root of multiplicity greater than one. By expanding the knowledge in the field, this study offers valuable insights into the resolution of linear recurrences and interpolation problems, presenting a new perspective and expanding the existing knowledge in the field.","PeriodicalId":281529,"journal":{"name":"Asian Research Journal of Mathematics","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114665864","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}
