Segmental arterial mediolysis (SAM) is an asymptomatic, non-atherosclerotic and non-inflammatory disease of unknown etiology. It affects medium-sized arteries and is characterized by vacuolization and lysis at the level of the media which can lead to dissection, steno-occlusion, or an aneurysm. In this article, a simulation of fluid-structure inter...

In this paper, the performance enhancement of solar gas heaters is evaluated by taking the advantage of both radiating gas effect and using converged ducts with the accelerated flow. The analyzed solar gas heater includes the glass cover, air gap, absorber, gas channel, bottom plate, and insulation. The inclined position of the bottom plate relativ...

Micropumps are revolutionizing compact and autonomous monitoring systems due to their portability and efficiency. In this paper, we present a valveless piezoelectric micropump design. This micropump distributes gas and liquid using a PDMS membrane that moves in response to a force applied by a piezoelectric actuator. The proposed design aims to ach...

Application of systems for passive vibration control is an efficient way for seismic protection of structures. Systems for passive vibration control consist of seismic isolation devices and energy dissipation devices. Base isolation of structures is a concept where devices for passive vibration control are placed in foundations of buildings. Variou...

Aerodynamic drag is still one of the main challenges facing the automotive industry. The design engineers are trying to develop novel techniques that could help to control the flow and optimize the shape of a vehicle to make it able to increase the base pressure drag at the wake region. The pressure drag is one of the main contributors to the aerod...

Hypertrophic cardiomyopathy is one of the most prominent cardiovascular diseases, with almost 1 in 500 people suffering from it. It is of great importance for this disease to be detected in a timely manner, so that patients can be provided with an adequate therapy. This is also important for monitoring the future development of the disease so that ...

Recent studies have attempted to find methods and techniques that enable the development of heat transfer within thermal transformers. For this purpose, this paper includes a numerical simulation of a non-Newtonian fluid inside a chamber with four hot bodies. The chamber is exposed to a magnetic field of constant and uniform intensity. Also, the up...

The introduction of pressure piping increasingly requires the use of efficient materials which must withstand both high hydrostatic pressures, high mechanical loads and high thermal gradients. At nuclear power plants, piping systems are subjected to high pressures (up to 60 MPa). The occurrence of cracks and their possible spread is one of the seri...
