Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

In this study, a new structure of the positive output super lift Luo (POSL) converter is presented. The major aim of this new converter is to provide ultra voltage transfer ratio gain. The basic (POSL) convertr has voltage lift circuit (cell), which contains single inductor, diode and capacitor. The disadvantage of the basic (POSL) converter is that it becomes the same with boost converter in case of increasing the output voltage at high duty cycle. The new converter provides ultra voltage transfer ratio gain by adding the switched capacitor inductor cell, which consists of two inductors, two diodes and one capacitor to the basic (POSL) converter and matching it with suitable connection. This allows gaining practically more than triple rise in the line to output voltage ratio. Pulse width modulation (PWM) voltage mode controller strategy is used to control the new converter. The new converter works by using two switches and they work instantaneously to make the control simple, more efficient and more effective. In addition, the equations of voltage and current in continuous and discontinuous conduction modes (CCM) and (DCM) are analyzed at steady state error. The simulation and practical results shows the effectiveness of matching the new converter to the theoretical analysis. The new converter has high efficiency that reaches 96.1% in comparison with the basic (POSL) converter, which has 94.1%. The simulation has done by using Matlab/Simulink program
This paper introduced new optimization method called improved salp algorithm to development totally covered area with low cost and low radiation in heterogeneous microcellular system for wireless private network. The sensible planning of deep coverage has become increased protrude for location and many base stations that can meet signal coverage of most outdoor environments, but some terminal stations are required with appropriate depth coverage systems and taken with consideration the deep indoors. The proposed algorithm (combine salp optimization algorithm with genetic) are used to complete indoor data collection and a deep coverage optimization. This method aim to improve the original algorithm with enhances the interaction ability between individuals and the information cross-mutation which used to improve the search speed of the algorithm. The simulation results show that the proposed algorithm can effectively optimize multi-target indoor wireless network planning
