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.

There are a wide variety of software packages for designing and sizing of solar PV system. However, all of them are at the commercialized level which is more sophisticated and costly. This paper presents a simplified designing tool for array configuration of the grid-connected solar photovoltaic (GCPV) system. A simple, free and user-friendly tool known as PV.xls was developed to determine the array configuration of a GCPV system which can be applied for green housing. This tool was created for educational purposes to assist those with a limited technical background to design and size the system. The tool uses a basic simple Microsoft Excel spreadsheet. Database of PV modules, inverters, and simplified sizing procedure for the calculation of array configuration is embedded in the spreadsheet. The calculation is based on Malaysia Standard MS1837:2010
This research is aimed at mapping the subsurface structures such as fracture, weathered basement and fresh basement for groundwater investigation at Oke-Odo, Iwo, Osun State, Nigeria using combined geoelectric and statistical approach. Six (6) vertical electrical resistivity sounding data are collected based on schlumberger electrode arrangement configuration and maximum current electrode spacing of AB/2 along 100m within the study area. The vertical electrical sounding (VES) results presented as resist graph revealed the range of values for all the VES stations respectively. The depth ranges from (0.9–37.5 m), thickness ranges from (0.9 – 35.1 m) and resistivity ranges from (27.3 – 3353.4 ohms). These results were later used to generate 2-D geoelectrical maps of the subsurface study area, which revealed that the fractured-weathered basement varied, leading to diversity in groundwater prospects. A descriptive statistic was computed for resistivity, thickness and depths values respectively from the resist graph. The normality of the data was examined using the Shapiro- Wilk’s test while test of homogeneity of variance was carried out using the Levene’s test. Resistivity between layers were compared using the ANOVA followed by Duncan’s test for Post Hoc comparison while thickness and depth between layers were compared using the independent t-test. The modeled geoelectric and statistical approach on the groundwater potential revealed that groundwater yield was recorded in areas with large concentrations of fracture and weathering with the bedrock
