Abstract: MHD Darcy-Forchheimer Slip Flow in a Porous Medium with Variable Thermo-Physical Properties was studied. The governing partial differential equations are converted into nonlinear ordinary differential equations using a similarity transformation and solved numerically. The variable and thermal conductivity were studied. Different physical parameters’ effects on temperature, velocity and concentration distribution are studied.  The effects of Darcy-Forchheimer parameter, suction/blowing parameter, velocity slip and thermal slip parameter on the velocity, temperature and mass transfer rates nature are examined with the aid of graphs. Schmidt number and Soret number effect are also presented. The results shows that when the porosity parameter is increased, the velocity of the fluid decrease, while temperature profile and skin friction decreases. Also increasing the velocity slip parameter result in increase in velocity and Nusselt number whereas the concentration decreases in same case. Also the temperature at a point decreases with increase in thermal slip parameter while the skin friction decrease in both cases.

Abstract: In this paper, based on a new multiplication of fractional analytic functions, we solve a problem involving fractional algebraic equations. The solutions of this problem can be obtained by using some methods. In fact, our results are generalizations of the results of ordinary algebraic equations.

Abstract: Each year, millions of elderly people—those 65 and older—fall [1]. Even the smallest fall for elderly citizens could lead to serious injuries and deteriorate their self-confidence [2].  In spite of using the walking sticks, many seniors lose balance. Many walking stick users hold onto nearby furniture/walls to maintain balance since most walking sticks are single handled. My research mainly focused on causes of their tripping or imbalance and redesigning the walking stick based on their input.

To improve the stability, a dual handle walking stick (Step-Up) has been designed using Autodesk® Fusion 360.

This foldable, User-Centered Design minimizes the chances of falling, and is designed to support both the user’s hands, especially when climbing up and down stairs.

Along with age, seniors also face hearing or vision problems, hence a SOS button and an Arduino UNO ultrasonic proximity sensor have been provided.  The SOS buzzer quickly alerts people nearby of any emergencies. The proximity sensor alerts the user of any obstacles with varying frequency of sounds based on distances.  Additionally, a multipurpose USB outlet is provided, which allows users to add a portable device of their choice: adding a mini fan during hot summers, a portable light, or charge a phone, etc. Step-Up, a smart walking stick, not only reduces the fear of falls and but also assists a peaceful walking experience for elderly.

Keywords: walking assistant, elderly walking, dual handle, fusion 360, Arduino uno, Ultrasonic proximity sensor.

Abstract: Suspension systems in modern vehicles are considered one of the essential parts in developing the vehicle industry; in the same way, they are the central part responsible for ride comfort and avoiding road obstacles. In this paper, some previous studies of passive, active and semi-active suspension systems have been reviewed. The focus was on reviewing the semi-active suspension system using MR damper technology to highlight the pros and cons of using MR. This could help to lead many researchers to deeply study this technology (MR damper) to reach the requirement.

Keywords: Quarter-car model, semi-active suspension, Passive suspension, Active suspension, MR damper model.

Abstract: In this paper, based on Jumarie type of Riemann-Liouville (R-L) fractional derivative, the exact solution of linear system of fractional differential equations with constant coefficients is obtained. A new multiplication of fractional analytic functions plays an important role in this paper. In addition, we also provide some examples to illustrate the application of our results. In fact, our results are generalizations of these results in ordinary differential equations.
