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.

Breast cancer detection is one of imbalanced classification problem in machine learning. The breast cancer dataset consists of significantly more class of non-cancerous observations than the cancerous observations. The classification of imbalanced dataset is a problem to machine learning algorithm due to the fact that the standard machine learning algorithms assume the class in the dataset are balanced or equal. The imbalance of the classes in breast cancer dataset makes the detection of breast cancer more difficult with the existing standard machine learning algorithms. This is because the algorithms are biased prediction due to the class imbalance in the dataset. In this research, a solution to imbalanced classification problem is proposed by proposing a weighted decision tree model for breast cancer detection. Finally, the performance of the proposed model is tested and result reveals an accuracy of 94.03% is achieved. Moreover, experimental test on the breast cancer dataset shows that better performance is achieved by the proposed model as compared to the standard decision tree model
Laser drilling is one of the earliest applications of lasers in materials processing. Less than 0.25mm in diameter are difficult to drilled mechanically. Laser drilling offers good choices for small hole drilling, especially for hard and brittle materials such as ceramics, but cracks appearance is one of the most difficulties that appears in this drilling. Therefore, this paper aims to study the effect of number of pulses on the drilling of soda lime glass (SLG) using under water laser drilling technique. A 1.15 mm thickness SLG sheets were immersed 1mm below the de-ionized water surface, then irradiated with CW CO2 laser. The laser parameters used were (19, 20.5 and 22) W power, (5, 7.5 and 10) sec exposure time and (2, 3 and 4) pulses. The drilled points were investigated under optical transmission microscope. Then the upper diameter, lower diameter, crack length and taper angle for these drilled holes were measured by analyzing the OM images using ImageJ software. Clearly appeared that hole diameter and the crack lengths could be controlled by the laser power and no. of pulses. When power or pulses were increased, the hole diameter increased. While the length of cracks is decreased with increasing no. of pulses and increased when the power increased. The good results found at laser power 24 W, five sec. and one pulse for hole diameter, while the minimum crack length was found at four pulses, five sec. and 19 W power
