The paper focuses on the heat and mass transfer over a vertical plate with buoyancy and chemical reaction under the influence of convective surface boundary conditions. We enhance and improve the work of Aziz and Makinde in order to integrate hydromagnetic mixed convection heat and mass transport over a vertical plate with a convective surface boundary condition as well as heat generation/absorption and reactivity characteristics [1,2]. Using self-similar variables, the equations governing boundary-layer flows were converted into a two-point boundary value problem, which was then solved numerically. To ensure that the asymptotic conditions is not affected for an imposed finite domain, the is taken to be large enough. The numerical computation was implemented using mathematical software Maple 2022 to execute the codes. We performed the computation in both hardware precision and arbitrary precision, by setting the digits to 20. The numerical result have been plotted to clearly show the effect of the governing parameters on the flow. In other to validate our result, we compare our results with existing published result when the improvement in the current work are taken to be zero the comparison was displayed in Table 1 which was in an excellent agreement. Our results amongst other, shows that local skin-friction coefficient, local heat and mass transfer rate at the plate surface increases with an increase in magnetic field, intensity of buoyancy force, convective heat exchange parameter and buoyancy ratio, increase in convective heat transfer increases the temperature and maximum concentration occurs with generative chemical reaction within the body of the fluid close to the surface. The effect of all other governing parameter were displayed graphically and discussed extensively.

Most thermal radiation problems are analyzed in a "forward" manner, in which the aim is to predict the response of a system based on well-defined boundary conditions. In practice, however, many thermal radiation problems are inverse problems. For example, the goal of many furnace design problems is to find a configuration that realizes a particular irradiation profile on a target, while in measurement problems, transmitted or reflected radiation measured with sensors at a boundary may be used to infer the properties of matter within the boundary. Such inverse problems are often mathematically ill-posed because they may have multiple solutions or no solution at all. Consequently, analyzing these types of problems is more complex than for "forward" problems. In this review, we examine the various types and characteristics of inverse problems, outline standard inverse solution methods for them, and review the historical and contemporary literature.
