Mohamed Bahloul: Africa-Middle East Finalist at the 2018 EMBC Student Paper Competition

Congratulations to Mr. Mohamed A. Bahloul, PhD student, who is the Africa-Middle East Finalist at the 2018 EMBC Student Paper Competition

Congratulations to Mr. Mohamed A. Bahloul, PhD student, who is the Africa-Middle East Finalist at the 2018 EMBC Student Paper Competition. Mohamed presented his work, on July 19th in Honolulu Hawaii, USA, in the 40th Annual Engineering in Medicine and Biology Conference. His paper entitled "Three-Element Fractional-Order Viscoelastic Arterial Windkessel Model" has been selected as the best scientific paper from Africa and Middle East region. 


In this work Mohamed and Professor Meriem Laleg have proposed for the first time a new Viscoelastic lumped parametric model of the systemic arterial system.

"The novelty of our work is that we have used in our model a new component that characterizes the viscoelasticity property of the blood vessel. This electrical component is a fractional order capacitor. It combines both elastic and viscous features of the arterial system in one component. Our model is very accurate and also simple: It is a reduced Model! In the future, we see that our model can be used as a diagnosis tool to predict the Cardiovascular Diseases, even before it is happen. In another word we hope that we can save life from this type of illnesses that leads the cause of death worldwide" Mohamed explained.

"My ultimate goal is to become a technological leader in bioengineering more specifically in cardiac physiology characterization who can skillfully address a variety of healthcare challenges." Said Mohamed A. Bahloul.

Here is the Abstract of the paper:‚Äč

Arterial hemodynamic assessment has always been essential for clinical Cardiovascular System diagnosis. Using Windkessel lumped parametric model as noninvasive measurement tool provides the potential of achieving a very convenient, computational inexpensive and accurate prediction of the arterial parameters. Many versions of WK models have been proposed and extensively studied, over the last century. In general, they can be classified into two categories: elastic and viscoelastic models. Recently, several studies have discussed the potential of describing the arterial wall viscoelasticity using fractional order models, reducing the number of parameters and exposing a natural response. Hence, a key missing item in the arterial Windkessel modeling is a fractional-order analog component that can provide a reliable, realistic and reduced representation of the fractional viscoelasticity behavior. In this paper, we present, for the first time, a three-element fractional-order viscoelastic Windkessel model. The proposed model incorporates a fractional-order capacitor that substitutes the ideal capacitor of standard three element WK model. The latter non-ideal element combines both resistive and capacitive properties which displays viscoelastic behavior of the arterial vessel. The contribution of both properties is controlled by the fractional differentiation order (alpha ) enabling an accurate and reliable physiological description.
