This research explored and examined how web-based distance education (WBDE) influenced adult learners then to learn about challenges and potential barriers of WBDE programs. Many studies have done on traditional distance education, but little research has done on WBDE for adult learners. WBDE has the goal to provide socio-technical innovations for E-learning practices, regarding individuals and organizations, independence of time, place and pace. These discussions and conclusions in this research explored the adult learner's perspectives and practices on WBDE; the barriers and challenges of...

The field activated sintering technique (FAST) is a powder consolidation process via the application of pulsed current and pressure. Compared with conventional hot pressing and hot isostatic pressing, FAST has demonstrated a rapid densification process that has the potential to minimize grain growth, which is crucial to achieving excellent physical properties. This work covers the physical phenomena, multi-scale analytical and numerical models, experimental studies, and application of FAST processing. Specifically, a coupled thermal-electric-densification framework for the design and...
