Due Date and Overdue Penalty• Due date for the reports:
- 2 weeks after the experiment date.- The date of submission is counted by the date on which the hard copies of your reports are handed in to and signed by Dale Claude.
AND- Electronic copies of the reports must be sent to both Dale and instructor by email on the same day for verification.- When submission on weekends, the date of submission of reports by email can be counted, however, the hardcopies of your reports must be handed in to Dale on the following Monday to avoid extra delay penalty.
- 7 “free” late hand-in days for the whole course - Must indicate on your reports when use it to avoid late
penalty.
Due Date and Overdue Penalty
Penalty- 10% of the full marks of each report per week (1.4%/day, including weekends, but not including other statuary Holidays) will be deducted from the late reports.
- Submissions including lab notebooks will NOT be accepted after
April 8, 2011.

Table of contents
Formal Technical Report
Abstract• State briefly the purpose of the investigation• Describe briefly how the results are obtained• Give all required results in a concise and
quantitative format if possible.• Use words, no tables, figures and equations• Normally no more than 250 words.
Formal Technical Report
Introduction• Include information on the subject of the
investigation and its importance in industry
• Cite the references;
• Describe clearly the objectives of the lab.
Formal Technical Report
Literature review or theory• Provide sufficient theoretical background
to the particular experiments• Develop the equations or models to correlate
your experimental data. Number the equations.
detailed derivation placed in Appendix• Describe how to obtain the model parameters
and predict the particular system• Cite the references
Formal Technical ReportApparatus and Experimental Procedures
• Specify the main apparatuses used make, model and use
• Describe the procedures Highlight important experimental conditions
• Give the names of quality of the materials.
Make sure other people can repeat your work and obtain the same results if they follow your description.
Formal Technical ReportResults and Discussions
• Present the significant experiment results required in the Lab Manual in words and graphs.
• State the data treatment processes and the outcomes.
• Discuss the results of experiments and model simulations or predictions.
• Compare your results with that in literatures if available.
• Logically discuss and lead to conclusions.
Attention• Consistent format• The unit for every parameters in the equations has to
be conformed. • Figures or Tables in the body of text
– Titles of figures, axes, and tables
– Briefly state the experimental conditions
– Experimental data: represented by unique symbol for each group of data in figures
– Modeling curves: different lines with legends– Show model significance when fitting models
