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.

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
