The present work investigates the impacts of the Lorentz forces, porosity factor, viscous dissipation and radiation in thermo-Marangoni convective flow of a nanofluids (comprising two distinct kinds of carbon nanotubes ($CNT_{s}$)), in water ($H_{2}O$). Heat transportation developed by Marangoni forces happens regularly in microgravity situations, heat pipes, and in crystal growth. Therefore, Marangoni convection is considered in the flow model. A nonlinear system is constructed utilizing these assumptions which further converted to ordinary differential equations (ODEs) by accurate similarity transformations. The homotopic scheme is utilized to compute the exact solution for the proposed system. The study reveals that higher estimations of Hartmann number and Marangoni parameter speed up the fluid velocity while the opposite behavior is noted for porosity factor. Further, the rate of heat transfer shows upward trend for the Hartmann number, Marangoni parameter, nanoparticle solid volume fraction, radiation parameter whereas a downward trend is followed by the Brinkman number and porosity factor. It is fascinating to take observe that contemporary analytical outcomes validate the superb convergence with previous investigation.

In this paper, we propose a different way for solving systems of nonlinear Fredholm integral equations of the second kind. We construct our new strategy in two steps, through beginning with the linearization phase of the system of Fredholm integral equations by applying Newton method, then we pass to the discretization phase for some involved integral operator using Nystr"{o}m method. The convergence analysis of our new method is proved under some necessary conditions. At last, a numerical application to approach a nonlinear Fredholm integro-differential equation by using this new process is taken to confirm its advantage.

Many studies have been conducted using obstacle hazard values, called potential method, for connected autonomous vehicle. However, most studies were conducted for static obstacles, and those for dynamic obstacles assumed an environment without oncoming or crossing vehicles. In this study, we devise an algorithm for generating potential values considering time series characteristics using information that can be obtained through inter-vehicle communication and propose a path ?nding algorithm that uses these potential values. As an evaluation of the usefulness of the proposed method, we compare it with existing potential methods. The results show that, in some situations, the route derived by the proposed method is superior to the route derived by the existing potential method in terms of safety and timer to reach the destination.

We introduce the concept of exponentially $s$-convexity in the second sense on a time scale interval. We prove among other things that if $f: [a, b]to mathbb{R}$ is an exponentially $s$-convex function, then begin{align*} &frac{1}{b-a}int_a^b f(t)Delta t &leq frac{f(a)}{e_{beta}(a, x_0) (b-a)^{2s}}(h_2(a, b))^s+frac{f(b)}{e_{beta}(b, x_0) (b-a)^{2s}}(h_2(b, a))^s, end{align*} where $beta$ is a positively regressive function. By considering special cases of our time scale, one can derive loads of interesting new inequalities. The results obtained herein are novel to best of our knowledge and they complement existing results in the literature.
