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.

Electronic ballasts allow to the discharge lamps to improve the quality of radiation by operating at high frequency. In this work, the design of a high-frequency power supply is proposed (multicellular converter series 4-cell based electronic ballast) to supply a low-pressure mercury-argon Ultraviolet-C (UVC) lamp for sterilization with a sinusoidal current of 50 kHz frequency and an effective value of 0.65A to have a germicidal effect for water purification (a maximum of UV radiation at 253.7 nm). The objective is the elaboration of modern control laws for a discharge lamp powered by a series multicellular converter for water sterilization. The control that we have used is the higher order sliding modes "super twisting algorithm", and for the converter, we have adopted the direct control. The performance evaluation of the proposed regulators was carried out by conducting several closed loop robustness tests
The volcanic area is blessed with a lot of resources and cursed with eruptive disaster at the same time. Fertile land, deep forest, mining deposit, and water reserve are examples of the potential within a volcanic environment. The more productive activity is taking place, the more it risks damaged by a disaster. In 2010, Merapi, an energetic volcano in Java – Indonesia, erupted on a massive scale equal to one event in one hundred and seventy years. It was estimated up to 140 million m3 lahars produced, overwhelming installed sabo dams with only 20 million m3 in capacity. It damaged these sabo dams severely. Meanwhile, damaged sabo dams urgently needs to be either rehabilitated or reconstructed to set preparation against the next incoming eruption. This paper would focus on the estimation of functional performance given by the sabo dam at present actual condition. The aim is to create modelling framework base on structural equation modelling (SEM). It adopts water resources principles, recent developed model, regulations and factors that influencing this purpose. All governing factors are grouped into three major classifications, i.e. physical aspect, regulative aspect and social aspect. Output will be governing aspects proportion of weight in assessing actual performance. The model will be useful to value sabo dam conditions in the framework of rehabilitation and reconstruction planning where a limited budget is present
