Aim
The aim of the course is to acquaint students with the basic concepts of blood flow from the point of view of mechanical engineering. Its topics include the basic concepts of physiology; history and modern solutions of blood pressure measurement; function of arterial and venous blood flow, basic concepts of signal processing, medical image processing, flow simulation methods. A basic knowledge of measurement concepts and signal processing tools is essential for this. The class covers computational fluid dynamics, medical imaging; boundary conditions, biomechanical processes; and the study of time-varying biological processes. as well as problem areas. Within the framework of the class, students complete 2 homework assignments in close connection with the theory. They report on their knowledge in two summative performance evaluations.

In some situations, as part of a team, he/she works with his/her fellow students to solve tasks. With his/her knowledge, he/she makes a responsible, well-founded decision based on his/her analysis. He/she independently thinks over tasks and problems and solves them based on the given resources. He/she is committed to the principles and methods of systemic thinking and problem solving.
Teaching methodology
The lectures basically introduce students to the information defined by the knowledge competence elements using the method of frontal education. Some of the lectures come with pre-published slide shows so students can add their own notes to the lecture. Based on the material of the lectures, the appropriate preparation for the partial performance evaluations can be achieved. During the project tasks, the competence elements can be deepened by performing and evaluating measurements and / or calculations closely related to the topic of the subject. To develop teamwork skills, students work in groups during project assignments and then create presentations and posters in groups about the work done.

General rules
Learning outcomes are assessed on the basis of two mid-year partial performance measurements. The first one is a project-type task; partial performance assessment in the form of a complex, written assessment of the elements of the subject's knowledge, ability and independence and responsibility type competences in the form of student documentation. At the end of the semester, an A3 format mini poster should be made about the completed task. The student is expected to appear prepared in the consultations. The other partial performance assessment is a method of assessing the knowledge, ability, attitude, and autonomy and responsibility type competence elements of the subject, which is an independently prepared summary of a scientific paper.
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | formative assessment, project-based, complex | |
| Number: | 1 | |
| Purpose, description: | Project-type partial performance evaluation examines and assesses the knowledge, ability, and autonomy and responsibility type competence elements of the subject. This is a complex, written way of evaluating, in the form of student documentation. As far as the nature of the task is concerned, it is solving a hemodynamic problem with modeling tools. When submitting the problem statement, applied methods and solutions; the documentation should be prepared around the results and summary. An A3 mini poster about the work should also be presented at the end of the semester. The student can get 80 points in the evaluation. | |
| Mid-term assessment No. 2 | ||
| Type: | formative assessment, simple | |
| Number: | 1 | |
| Purpose, description: | The basic goal of partial performance assessment is to examine the existence of learning outcomes belonging to the competence group of ability, attitude, and autonomy and responsibility. One way to do this is to have an independent summary of up to two pages of a recent scientific paper. A maximum of 20 points can be earned with the summaries. The deadline for submitting summaries is the end of the 14th educational week. | |
Detailed description of assessments performed during the examination period
The subject does not include assessment during the examination period.
The weight of mid-term assessments in signing or in final grading
| ID | Proportion |
|---|---|
| Mid-term assessment No. 1 | 80 % |
| Mid-term assessment No. 2 | 30 % |
The condition for signing is that the score obtained in the mid-year assessments is at least 50%.
The weight of partial exams in grade
There is no exam belongs to the subject.
Determination of the grade
| Grade | ECTS | The grade expressed in percents |
|---|---|---|
| very good (5) | Excellent [A] | above 90 % |

| Can the submitted and accepted partial performance assessments be resubmitted until the end of the replacement period in order to achieve better results? | ||
| yes | ||
| Taking into account the previous result in case of improvement, retaken-improvement: | ||
| out of multiple results, the best one is to be taken into account | ||
| The way of retaking or improving a partial assessment for the first time: | ||
| partial assesment(s) in this group can be improved or repeated once up to the end of the repeat period | ||
