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 work presents the results for determining the optimum exchanged wheel diameter when surface grinding stainless steel. To do that, an optimization problem with the target is the grinding time was conducted. Also, the impact of many input factors including the initial wheel diameter, the wheel life, the radial grinding wheel wear per dress and the total depth of dressing cut on the optimum replaced wheel diameter was evaluated. In addition, a regression model to predict the optimum replaced diameter was proposed
The preparation of clay-TiO2-S composite as adsorption-degradation material has been carried out. Clay-TiO2-S composite is obtained by mixing clay with TiO2 powder doped S for the pillarization method. Clay characterization was performed using SEM and FTIR. The characterization results showed that there were differences in the pore of the clay before activation and after activation. Activated clay designated that clay was a type of montmorillonite. The TiO2-S composite was analyzed using UV-Vis DRS which indicated a change in anatase TiO2 bandgap of 3.2 eV to 3.0 eV. The results of FTIR analysis on clay-TiO2-S composite specified a new peak that was different from the results of FTIR analysis of activated clay and indicated the presence of Ti-O adsorption bands and the strain of S-H, S-N, and S-O. Methylene blue adsorption was optimally achieved by clay adsorbents at 30 minutes contact time on 1.553 mg.g-1 with an adsorption efficiency of 86.41%. Optimum degradation of TiO2 was occured at 90 minutes contact time on 1.590 mg.g-1 with a degradation efficiency of 88.46%. The optimum adsorption-degradation of clay-TiO2-S composite (material mass 0.5 g) showed an adsorption power of 0.337 mg.g-1 with an adsorption efficiency of 93.87%, while the optimum degradation power is 0.341 mg.g-1 with a degradation efficiency of 94.94%. Clay-TiO2-S composite showed a great potential with a adsorption-degradation working system in the treatment of environmentally friendly textile waste in the future
The purpose of this work is to study the influence of the shading rate on the different performances of a photovoltaic device. An experimental study of a special boost called MCB (Magnetically Coupled Boost) developed by the research team at the LMOPS Laboratory. The influence of shading on boost performance is discussed through this phase of experimentation system and reduce the cost of the network and the cost of maintenance. The experimental procedure is based on the measurement of currents and voltages on the DC bus. Based on the shaded area (number of shaded cells) of the module of different shading configurations with a constant illumination
The world is thinking more and more about the importance of improving the quality of life, ensuring normal living and working conditions. Practical sources of improving the quality of concrete and accelerating the formation of its structure will replace traditional methods that do not provide sufficient efficiency. This article presents improvements in concrete technology, the use of micellar catalysis and the ultra-low dose effect, which were previously only used in organic technology
Wettability is one of the parameters controlling fluid distribution and flow behavior in a porous media. The spontaneous imbibition is a major indicator for the type of wettability. A lot of qualitative and quantitative methods for wettability measurement were presented in the literature. The quantitative methods usually depend on the direct volume measurement for spontaneous imbibition evaluation. The weighing technique was equipped in this research to measure the spontaneous imbibition in addition to the direct volume measurement. Samples of different sizes taken from the same rock source were used. Results shows that there is a difference between the averaged values resulted from the weighted method and that resulted from the direct measurement. Also, there is a difference between the ultimate water saturation value for these samples in spite of that all of them are from the same source
