This course is mainly concerned with cutting-edge concepts and methods in a state of the art that is still evolving, it does not require a 100 per cent written exam.
Students are assessed using the group work in the workshops (GW), by reading a conference/journal article and presenting it to the peers at the end of the semester (RP), and writing an individual research paper (IR) to be delivered ar at specific date during the 1st examination period. The grade is calculated by: 0,3 x GW + 0,3 x RP + 0,4 x IR.

Students are assessed through:
(a) group work in workshops (GW),
(b) presenting a conference or journal paper (RP) to peers (at the end of the semester)
(c) an individual research paper (IR) (on a set date in the 1st term),
according to the formula: 0.3 x GW + 0.3 x RP + 0.4 x RI.
For approval, any assessment element requires a minimum mark of 8.

Model 2 (Grade Improvement):
If students are not satisfied with their results from Model 1, they may complete a group project (with up to 4 members), which will account for 30% of the final grade. The remaining 70% will be based on the results from the Regular Assessment.
