The Given

In this article, the iterative transformation method and homotopy perturbation transformation method are applied to calculate the solution of time-fractional Cauchy-reaction diffusion equations. In this technique, Shehu transformation is combined of the iteration and the homotopy perturbation techniques. Four examples are examined to show validation and the efficacy of the present methods. The approximate solutions achieved by the suggested methods indicate that the approach is easy to apply to the given problems. Moreover, the solution in series form has the desire rate of convergence and provides closed-form solutions. It is noted that the procedure can be modified in other directions of fractional order problems. These solutions show that the current technique is very straightforward and helpful to perform in applied sciences.

Air Control

For controlling emergency escaping by a bus driver in the case of air control door cannot be opened normally, the paper presented a multi-manual emergency escaping system of pneumatic bus door. Bus driver and passenger can control doors expediently. The pneumatic circuit of the system and its overall arrangement is discussed. A manual control device with special valve core structure is designed. The working performance of the manual shift directional valve is analyzed. The results indicate that driver and passengers can control the bus doors under the state of abnormal condition via manual control devices in series connection rapidly. Driver and passengers control is without mutual interference. Manual shift directional valves are convenient, reliable and fast.

Quadratic Performance

Abstract In the paper, mathematical models of the supercapacitors are investigated. The models are based on electrical circuits in the form of RC ladder networks. The elementary cell of the network may consist of resistances and capacitances that are connected in series or parallel. The dynamic behavior of the circuit is described using fractional-order differential equations and its properties are analyzed. The identification procedure with quadratic performance index is performed in time domain to identify the parameters of the supercapacitor models. The results of numerical simulations are compared with the results measured experimentally in the physical system. In addition, an example from the automotive industry is used for an experimental evaluation of the theoretical analysis and to present a perspective on the applicability of the approach for other industrial projects.
