Abstract: In this paper the developed software for simulation of the temperature distributions in the cast ingots at electron beam drip melting for different materials is presented. The influence of the change of the process parameters electron beam power, casting velocity and the beam radius on the temperature distributions in the cast ingot and the parameters of the molten pool can be investigated. Quasi steady-state two-dimensional heat model is implemented for the simulation of the temperature distribution in the cast ingots from different materials.

Abstract: Effective teaching-learning participation in e-Learning necessitates both students and instructors to strike a balance of respect and tolerance with one another. In this perspective, participation in e-Learning does not differ much from participation in a conventional face-to-face classroom. In fact, the former requires a broader set of rules and policies to establish proper ethical conduct to avoid, if not resolve, actions that may be deemed inappropriate in e-Learning. In light of this awareness, this paper explores the actions of ethical conduct of e-Learners and e-Instructors in Blended Learning Approach, an e-Learning platform/portal at The University of Jordan. Discussion is further explored with some thoughts on current and future challenges facing the ethical perspectives of e-Learning within the Jordanian context.
