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.

Renewable energy comes with a great deal of hope for a better planet with low CO2 emissions and unlimited sources. One of these promising sources of energy is the one that comes from the sun. Solar energy harvesting can be combined with the ever famous IoT monitoring. The current internet connection and speed can meet the need for an online and up-to-date view of the performance of the PV system. This paper compares data from IoT monitoring and direct measurement of PV panels. The experiment was conducted by installing two panels with different means of output and efficiency monitoring. The difference in output between IoT-based monitoring and direct measurement is 2.9708 watt, and the efficiency difference is 3.085%. While the measurement is different, the graphic profiles are the same, indicating that the IoT monitoring and direct measurement can display the same data with the appropriate calibration and light sensor.
In this paper, the effect of flexural reinforcement ratio on shear capacity of steel-fiber reinforced concrete (SFRC) beams without coarse aggregate and transverse reinforcement was investigated. Six pairs of concrete beam specimens with the size of 70 mm × 125 mm × 1100 mm and shear span to effective depth ratio of 45/10.5 were tested using two-point symmetric top loading. The flexural reinforcement ratio varies from 0.0073 to 0.0782 with 0.1 percent steel fiber ratio of the total mass. The increase in shear capacity has been proven by the test results. However, this increase turns out to be insignificant as the flexural reinforcement ratio approaches its maximum value. Transverse reinforcement is required when the flexural reinforcement ratio approaches its minimum value. Fiber reinforced concrete without coarse aggregate has lower shear capacity than that of normal concrete and closes to the lower bound value of the Joint ASCE-ACI Committee’s test results for normal concrete. The shear capacity contributed by concrete proposed by ACI, which remains unchanged for decades, is only applicable for normal concrete.
