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.

This paper presents a method that can be used in selecting a mathematical model for estimating diffuse irradiance on vertical surfaces from the available horizontal sky irradiance measurements. It is based on the use of the ISO/CIE standard general sky model as a tool for selecting a diffuse irradiance model. Real measurements of solar irradiance are used to validate such approach
In sand blasting systems, the cleaning cost plays an essential role and greatly relies on many parameters e.g., nozzle diameter, nozzle lifetime, cleaning rate, etc. This study presents the procedure to compute the cleaning cost based on the price of cleaning system, price of abrasive, and price of nozzle when sand blasting with silicon carbide nozzles. The exchanged diameter of the nozzle was figured out by minimization technique of the cleaning cost function. Furthermore, using the experimental design method, the behaviors of seven input variables to the optimal exchanged diameter of the nozzle were examined. Using Minitab@19 for the experimental design was also proposed. The results illustrate that the input variables not only have on the optimal exchanged diameter of the nozzle, but also the interactions of these variables importantly affect the output variable. In addition, the mathematic equation was established in order to predict the optimum replaced diameter of the nozzle. This is greatly meaningful for sand blasting process due to decrease the cleaning cost.
