TL;DR: A two-dimensional theoretical study of hemodynamics through a diseased permeable artery with a mild stenosis and an aneurysm present and the effect of metallic nanoparticles on the blood flow is considered, motivated by drug delivery (pharmacology) applications.
Abstract: This article presents a two-dimensional theoretical study of hemodynamics through a diseased permeable artery with a mild stenosis and an aneurysm present. The effect of metallic nanoparticles on the blood flow is considered, motivated by drug delivery (pharmacology) applications. Two different models are adopted to mimic non-Newtonian characteristics of the blood flow; the Casson (viscoplastic) fluid model is deployed in the core region and the Sisko (viscoelastic) fluid model employed in the peripheral (porous) region. The revised Buongiorno two-component nanofluid model is utilized for nanoscale effects. The blood is considered to contain a homogenous suspension of nanoparticles. The governing equations are derived by extending the Navier-Stokes equations with linear Boussinesq approximation (which simulates both heat and mass transfer). Natural (free) double-diffusive convection is considered to simulate the dual influence of thermal and solutal buoyancy forces. The conservation equations are normalised by employing appropriate non-dimensional variables. The transformed equations are solved numerically using the finite element method with the variational formulation scheme available in the FreeFEM++ code. A comprehensive mesh-independence study is included. The effect of selected parameters (thermophoresis, Brownian motion, Grashof number, thermo-solutal buoyancy ratio, Sisko parameter ratio, and permeability parameter) on velocity, temperature, nanoparticle concentration, and hemodynamic pressure have been calculated for two clinically important cases of arteries with stenosis and an aneurysm. Skin-friction coefficient, Nusselt number, volumetric flow rate, and resistance impedance of blood flow are also computed. Colour contours and graphs are employed to visualize the simulated blood flow characteristics. It is observed that by increasing the thermal buoyancy parameter, i.e. Grashof number (Gr), the nanoparticle concentration and temperature decrease, whereas velocity increases with an increment in the Brownian motion parameter (Nb). Furthermore, velocity decreases in the peripheral porous region with elevation in the Sisko material ratio (m) and permeability parameter (k'). The simulations are relevant to transport phenomena in pharmacology and nano-drug targeted delivery in haematology.

TL;DR: In this paper, a sliding-mode control (SMC) for voltage source inverter (VSI)-based higher-order circuit is proposed in which the SMC is used at the inner terminals for stable tracking of the voltage and current variables An outer voltage control loop is included to reduce the steadystate error in tracking the reference load voltage.
Abstract: In this article, a new control methodology of sliding-mode control (SMC) for voltage source inverter (VSI)-based higher-order circuit is proposed In this method, the SMC is used at the inner terminals for stable tracking of the voltage and current variables An outer voltage control loop is included to reduce the steady-state error in tracking the reference load voltage It is shown that when the SMC is applied on the load voltage terminal for higher-order VSI circuits, it leads to the instability However, it well stabilises the system when the controller is implemented on the inner shunt capacitor terminals Additional outer voltage control loop with proportional plus integral controller will ensure regulated voltage across the load It has been shown that the controller is able to achieve good tracking accuracy with an acceptable stability margins The performance of the proposed SMC has been verified on the fourth-order VSI circuit
