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 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
This paper presents experimental research to determine the influence of cutting parameters on surface roughness when fine milling of spiral bevel gear. Three parameters of the cutting parameters investigated in this study include cutting velocity, feed rate and depth of cut. The test material used in this study is 20XM steel. The cutting tool used in this study is a hard alloy coated with CVD Ti (C, N)-Al2O3-TiN. The testing process were carried out with 15 tests in the form of Box-Behnken planning. The results of analysis of testing data have determined that the cutting velocity is the parameter that has the most influence on the surface roughness of teeth, followed by the influence of the feed rate. The depth of cut has a negligible influence on the surface roughness of teeth. The interaction influence of the parameters on teeth surface roughness was also discussed in this study. This study has also proposed a surface roughness model - using this model to predict surface roughness and proposing development directions for further studies
