RCOE Kickoff Meeting
Technical Review
For Each Task :- Technical Merits- Relevance- Technology Transfer / Technical Approaches
Emphasis on- basic research in nature, but relevant- unique technical contribution- creativity, innovation
PENNSTATE1 8 5 5
Guidelines for Presentations :
• 15 min for presentation• need time for discussion
• Explain in terms of physics, physical phenomena- technical barriers / challenges- unique contribution- creativity, innovation, new concepts, new understanding, breakthrough
• Don’t spend time on equation derivations, test setup, or code/grid developments (use as backup material, if wanted)
• planned accomplishments with the end goals (use Gantt chart covering 01-05, if desirable)
PENNSTATE1 8 5 5 Review Members
• Help presenters to observe their assigned presentation time
• Need good technical discussion after presentation- basic research in nature
- relevance
• No Funding issues
