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.

In recent years, the natural fibre such as kenaf fibre have been studied extensively. In this study, an experimental investigation was conducted to explore the effect of stitching technique of plain woven kenaf fabric on 3D hemisphere pressure clamped test. There were eight types of stitching patterns applied to the kenaf fabric. These patterns were divided into two categories that were single and double stitch patterns. Single stitching includes Vertical, Horizontal, Tilt 30° and Tilt 60°. Double stitching includes Box, Tilt 45°/90°, Tilt 30°/30° and Tilt 60°/60°. The radius of the hemispheric punch was 40 mm and the compression hemisphere displacement was fixed to the woven kenaf fabric by 40 mm. The clamps were placed on the plane plate, where the pressure was transformed from the hemisphere punch to the specified position on the stitching fabric with two supporting clamping tools. Box stitched pattern was found to indicate the highest compressive load of about 1.43 kN compared to other stitching patterns. Double stitching has a significant effect on 3D hemisphere pressure clamped test performance which enables an average improvement of 50 percent above the unstitched sample. This is due to the double cross stitch of the design of the box, the stress is distributed equally at 90° and 0°In recent years, the natural fibre such as kenaf fibre have been studied extensively.

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
