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.

Supply chain (SC) lays out the heart of every industry, including the automotive industry. Recently, several studies in SC has been conducted to look for the innovation that potentially adopted to gain the value-added for the industry. In this line, SC in the automotive industry is a very complex process and required the high standard for the product such as a car. In this context, the companies are collaborating to supply the component for the automotive industry. However, a single component defect might cause huge financial losses for the company or life. Technically, the new Blockchain technology with matching features is required by automotive. In this set, SC explores the possible adoption. This bibliography descriptive research is facilitated by Publish or Perish tools to gather the high-quality works of literature from Scopus index database. It also used VosViewer tools to process the thirty-seven papers found to visualize the development trend of SC Blockchain Technology based in the automotive industry. The study revealed essential Blockchain Technology research in the automotive industry started in 2017 and eight essential relevance terms or important factor for the automotive industry
The article deals with the internal ballistic of an air gun that utilizes the energy of compressed air to propel the projectile out of the barrel. In this study, a thermodynamic mathematical model describing the internal ballistic phenomena inside the working chambers of an airgun is developed. The core of this work is to derive a governing equation modeling the variation of gas temperature in a control volume including one or several incoming and outgoing mass airflow rates. A novel universal algorithm that allows to solve internal ballistics of all types of airguns is also developed and applied for the case of spring-piston airgun. To verify the mathematical model, the projectile muzzle velocity is measured using a Dopler radar system and compared to the theoretical result. The comparison reveals that the measured and calculated results of the projectile muzzle velocity are well agreed with the deviation less than 4%. Thus, the developed internal ballistic model of airguns and its solving algorithm can be used as a powerful tool to predict and improve the existing airguns performance or to design novel airgun systems.
