A numerical Solution of the Nernst-Planck equation for ionic polymer metal composites fixed-fixed beam is required for measuring deflection and stress of IPMCs. These results are extremely important for analyzing this material under variable voltage and preparing it for using in complicated accessories and using it in introducing the material behavior in electromechanical analysis. As a new smart material, ionic polymer metal composites, or in short IPMCs, are typically fabricated by coating noble metals such as gold, platinum, and palladium on each other sides of membrane-based on perfluorinated materials such as Nafion and Flemion. These composites can bend significantly by applying a low amount of voltage. In this research after creating a 2-dimensional model, the equations are applied to the finite element method, then the boundary co..... ReadMore

Mexico is the world largest producer of cactus pear (Opuntia spp.) and is searching for new processes that allow to export them. The fruit is rich in nutrients but is highly perishable having ambient shelf life of 9 days. Cauterization and cryo-cauterization techniques have increased shelf life to 2 and 3 months without refrigeration. An automatic system was developed to flip the fruit towards the dry-ice wall inside a chamber. A horizontal actuator pushed the container to cauterize the fruit. The entire cauterizing process for each fruit lasted 23 seconds. By exchanging the dry-ice wall every 500 fruits, a 100% cauterizer efficiency was achieved...... ReadMore

Global efforts towards minimizing greenhouse gas emissions are required to reduce the environmental issues caused by conventional combustion engine vehicles. Alternate clean and green modes of transportation such as electric vehicles are required in place of conventional vehicles. As a cheaper version of electric vehicle, electric rickshaws (popularly known as E-rickshaws or tuk-tuks) are most popular in India. This work deals with the modeling of popular e-rickshaws in MATLAB/Simulink. Software simulations are much helpful for quickly analyzing the distinct features of the electric vehicle, such as aerodynamic design, battery energy density, motor output, curb weight, etc and to visualize the effects on its performance due to variation in various parameters. Therefore, simulations were performed with Simulink model of hybrid solar e-ric..... ReadMore

Models are widely used in all sciences to simplify the most complex problems in reality, allow a representation of the behavior of a system and acquire great relevance in Geological Engineering.The conceptual geological model is very useful for projects developed in the field. Geotechnical models have evolved in parallel to computer-assisted techniques, from 2D to 3D models. The correct modeling of the physical-mechanical properties contributes to obtaining a representation of the characteristics of the geological object.The low availability of soils in the city of Caimanera, province of Guantánamo, appropriate for construction, has forced the use of swamp areas for urban development, through the use of low-thickness fill materials. The execution of constructions on swamp areas and low plasticity soils contributes to the increased risk o..... ReadMore

Cold spray is a coating technique that allows for solid state deposition of particles under atmospheric conditions of pressure and temperature. In cold spray micron size particles are impinged upon a substrate as a result of high velocity impact. The acceleration of particles to a high velocity is achieved by expanding a pressurized gas in a supersonic convergentdivergent nozzle. The performance of cold spray technique can be judged by several parameters, one of which is the deposition efficiency based on impact velocity. It is observed in this work that particles having small diameters achieve high velocities during nozzle acceleration, but they also decelerate rapidly in the flow downstream of the bow shock wave because of having low momentum. The main concern of this paper was to examine the effect of particle size on impact velocity i..... ReadMore

A novel fuzzy based control design for the trajectory tracking of wheeled mobile robot (WMR) is presented in this paper. This approach can be applied to generate trajectory tracking control commands on WMR movement. The design objective is to specify one fuzzy control law that can force the WMR to track a predefined trajectory for the nonlinear trajectory tracking control of WMR. In general, it is hard to obtain the closed-form solution from this nonlinear trajectory tracking problem, hence we try to treat this trajectory tracking problem from the so-called fuzzy control design concepts. Finally, one testing scenario: circular reference trajectory tracking is applied to performance verification..... ReadMore
