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 paper shows an optimization study on optimum determination of the cutting parameters and cutter helix angle when end milling of Al6061. In this study, the effects of the milling process parameters and tool geometry, including the cutting velocity, feed rate, radial depth of cut, and cutter helix angle. Moreover, in order to estimate the influences of these factors on the optimum cutting parameters and helix angle, a simulation experiment was designed and conducted by a computer program. A regression equation was proposed to calculate the optimum cutting speed, feed rate, radial depth of cut, and cutter helix angle.The Particle swarm optimization algorithm (PSO) was proposed to obtain the optimal parameters in consideration of the boundary conditions, which are determined from the empirical relationship of factors affecting the machining process
Education and mathematics competencies and skill have become the most central elements that impact on the development of any nation, particularly in science and technology. The fundamental importance of mathematics to humans could be explained in terms of the interrelationship between mathematics and the development of humans to advance the cause of humans. In this paper we report on a qualitative study which explored the mental constructions made by grade 12 learners (n = 30) when solving triangles in trigonometry. The study was carried out at a school in KwaZulu-Natal in South Africa. The data was collected from written responses of students to a structured activity sheet, consisting of questions on three dimensional problems. The data were analysed using APOS theory. Findings emanating from the data analysis informed a modification of the initial genetic decomposition, which raised some didactical implications for basic education, specifically for the learning and teaching of trigonometry
