Abstract: Electrochemical honing (ECH) is an electrolytic precision micro-finishing technology based on the hybridization of the electrochemical machining and conventional honing process. The ECH technology provides the controlled functional surface generation and fast material removal capabilities of work piece in a single action. This paper presents the distinctive findings of wide-ranging experimental research designed to explore the effect of key ECH process parameters on the workpiece surface micro-geometrical and material removal aspects. In the present work, an experimental setup was designed to study the effect of key parameters on the performance of internal surface and geometric characteristics. The electrolyte concentration, rotary speed, sticks out pressure and flow rate are process parameters selected for the experimental work. Design of experiment is employed for conducting the experiment and analyzing the data. Quadratic equations have been developed to analyze the effect of param

Abstract: The advance of mobile learning technologies has led to a new research issue in education, that is, the development of educational assessment with personalized learning system supports. In the meantime, it also becomes a challenging issue to evaluate the students learning achievement in mobile environment. In this paper, an integration of student modeling system with dynamic assessment strategy and context recommendations is proposed. This combination is able to guide the student to the proper level of performance by providing him with the necessary hints and learning material recommendations. The theoretical basis of dynamic assessment produce a proper mediation to help learners to apply some necessary principles to independently solve problems and thus learn more, plus provide more accurate individual knowledge estimation. Moreover, proper learning materials are suggested to the students to support their understanding and development of their knowledge level.
