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
Software watermarking refers to the process of concealing/hiding information in a source code or program to ensure its protection from piracy. Such information hiding is important since software piracy is one of the problems encountered in the software industry that leads to great financial losses annually. Software protection from piracy requires several prevention measures that will ensure the protection of the copyright of its codes; such protection can be provided using both software and hardware. Regrettably, there is currently no single technique that is robust enough to protect software codes from piracy. However, software developers are currently considering a combination of different approaches that will ensure better protection of software codes from piracy; such methods include encryption, watermarking and steganography. In this paper, authors address this issue through a prevention technique which is software watermarking in conjunction with encryption. Our software watermarking proposed scheme is based on some of the unique code features such as (Semicolon;, round brackets ( ), square brackets). Therefore, the main thought of the suggested scheme is using these features of any language programming to embed watermark information using the new proposed scheme called the White Space Scheme (WSS). Chaotic map is used to encrypt the watermark image before embedding the algorithm of the watermarking software. The experimental test and performance analysis have two parts for watermark encryption and software watermarking and have demonstrated better performance of the proposed scheme in terms of space size, time execution and security
This research intends to investigate the effect of rainfall intensity and fertilizer use to NPL (Nitrogen, Phosphate, and Kalium) content that also carried away together with run-off. Questionnaire about the application of fertilizwe that is commonly used is distributed to farmers. The modeling is carried out by using yje rainfall simulator of hydrology system SK-III Armfield. When the rain is dropped, the run-off will be directly taken as the sample to be tested in the laboratory for knowing the NPK content that is also carried away.The methodology uses linier regression statistical analysis and variance analysis for reaching the aim of research. Result of laboratory test shows that the rainfall intensity and the dose of fertilizer use is influencing tohether to the Nitrogen (R2 = 0.787), Phosphate (R2 = 0.49); and Kalium (R2 = 0.489). Result of variance analysis test indicates that the Nitrogen, Phosphate, and Kalium in run-off is affected by the rainfall intensity and the dose of fertilizer use
In this paper, the Box-Jenkins methodology representing the Autoregressive Integrated Moving Average ARIMA time series model has been used to study the patterns of injured people caused by road traffic accidents in Erbil city as well as making a monthly forecast. A monthly accident data of injured people from January 2013 to June 2018 were obtained from the General Directorate of Traffic in Erbil Governorate. The results showed that the series has features of seasonality and the number of injuries due to traffic accidents is decreasing in most months of the year. Some suitable models were developed and SARIMA (0,1,1)(1,0,1)12 was stated as adequate and the best model depending on some performance measures. A monthly forecast was made using the best model and it showed that the number of injured cases due to traffic accidents would continue to decrease in Erbil city to the end of December 2020
