Bio-medical studies

Science And Engineering Discipline

Biomedical Engineering Activity in online environment

• Developed by ORT Israel for the Ministry of Education.

• In cooperation with the Bio-Medical engineering faculty of Ben-Gurion University.

• Under the supervision of Prof. Ofer Barnea (head of the bio-medical engineering department in Tel-Aviv University).

• Designed for students with high learning abilities in science and engineering.

• Provides skills needed in the academic field. – research– independent thinking– team work.

• On-Line environment.

Bio-medical studies Fields of studies

• Physics , Chemistry or Biology

• Engineering Sciences

• Integrated projects - Electronics - Algorithmics- Bio-Medical Engineering

• The program is based on Analogies Theory.

What is Analogies Theory ?

• Analogies are fundamental concepts, thought processes or mathematic patterns, used in a variety fields of science.

• Learning by analogies helps the student develop a broad perspective of science and technology.

What is Analogies Theory ?Examples

• Minimum energy• Magnification • Resonance • Waves• Feedback and control• Analysis of the graph gradients (derivatives) • Analysis of the area below a graph (integral)• Exponent expansion rate

Bio-medical studies On-Line environment

• Completely Interactive

• No books are required

• Teacher-Student interaction via Internet

Activity ExampleMeasuring a walking man motion,

and filtering the measurement's noise.

Required equipment:• Webcam• Internet• Excel• Videoxp (a video editing software).

Phase1:Download the instructions file.

• Phase 2: Take a video clip of a walking man.

• Phase 3: Follow the man’s movement (center and gravity) using Videoxp.

• Phase 4: save the movement data on a spreadsheet (time, location, x-axis, y-axis).

Phase 4: save the movement data on a spreadsheet (time, location, x-axis, y-axis).

Phase 5: Ignore X-axis

Phase 6: In order to reduce the ponit’s noise, calculate the average of each 3 sequential points.

Phase 7: calc the speed of center

Phase 8: calc the acceleration of the center

Phase 9: calc the effort invested in the walk.

Phase 10: calc the power
