Apply the modelling approaches developed during the VO lectures to solve fundamental and advanced problems of transport phenomena in biological systems. Examples will include: Calculation of pressure-drops and mass flowrate inside catheters for analgesia; Computation of the cell growth on scaffolds; Development of recursive models for microparticles deposition inside the respiratory system.

The first UE lecture will be Tuesday October 9, 2018.

Exam:

During the course you will be asked to solve some proposed exercises and to prepare a report. The preparation of the report is mandatory to take the exam.

Structure of the exam:
-) The final exam consists of 2/3 problems
-) Each problem is divided into parts (2 or 3, typically).
A score is associated to each part (the maximum cumulative score considered to calculate the final grade is 100).
You should solve each problem by applying the correct equations and by providing the required results.

Scores:
Your grade will be assigned as follows:
SCORE                GRADE
<50   -> (fail)          5
51-65 -> (pass)      4
66-73 -> (pass)      3
74-85 -> (pass)      2
>86 -> (pass)         1

NOTE: Depending on the overall behavior of the class, the score ranges given above might change and shift towards lower values.
For instance, if scores are all below 85  then  ranges could be as follows:
SCORE                GRADE
<45   -> (fail)          5
46-60 -> (pass)      4
61-68 -> (pass)      3
69-80 -> (pass)      2
>81 -> (pass)         1
