Optimization of engine parameters using NSGA II for the comprehensive reduction of emissions from VCR engine fuelled with ROME biodiesel

Murugapoopathi Saravanamuthu et al.

Summary: Diesel engines are widely used due to their higher torque, power output, energy content per unit mass and cost of fuel, but they also produce harmful emissions. Researchers are exploring alternative fuels, such as biodiesel, to reduce environmental pollution. Rubber seed methyl ester (ROME) is a biofuel that can be used in existing diesel engines without any modifications.

Simulation of Mechanical Heart Valve Dysfunction and the Non-Newtonian Blood Model Approach

Aolin Chen et al.

Summary: This paper thoroughly reviewed the simulation of physical quantities in healthy and dysfunctional mechanical heart valves (MHV), as well as the non-Newtonian blood flow characteristics in MHV. The study found that dysfunction in MHV can affect simulation results and increase the risks, highlighting the need for more detailed and realistic simulations.

Biomaterials Based on Carbon Nanotube Nanocomposites of Poly(styrene-b-isobutylene-b-styrene): The Effect of Nanotube Content on the Mechanical Properties, Biocompatibility and Hemocompatibility

Maria A. Rezvova et al.

Summary: Nanocomposites based on poly(styrene-block-isobutylene-block-styrene) (SIBS) and single-walled carbon nanotubes (CNTs) were prepared with improved dispersion using dodecylamine (DDA) modified CNTs. The tensile strength of the nanocomposites with low molecular weight SIBS was increased with the addition of functionalized CNTs, while high molecular weight SIBS showed no significant improvement. The nanocomposites demonstrated enhanced biocompatibility, but high concentrations of CNTs could cause platelet aggregation.

Parameterization, geometric modeling, and isogeometric analysis of tricuspid valves

Emily L. Johnson et al.

Summary: Tricuspid valve regurgitation affects approximately 1.6 million patients in the United States, but research attention on the tricuspid valve remains limited compared to other heart valves. This study establishes a parameter-based approach for modeling and simulating the tricuspid valve, providing insights into valve performance and effectiveness. The proposed methods lay a foundation for future investigations of native valve configurations and optimization of prosthetic valve designs.

Patient-specific computational evaluation of stiffness distribution in ascending thoracic aortic aneurysm

Marzio Di Giuseppe et al.

Summary: This study utilized the LESI method to evaluate local stiffness properties of ATAAs, revealing strong positive correlations between local ATAAs stiffness and aortic pulse pressure, as well as patient age in BAV ATAAs. However, there was no significant correlation between local ATAAs stiffness and wall shear stress. Additionally, no significant difference was found in the extensional stiffness between BAV ATAAs and TAV ATAAs.

Global epidemiology of valvular heart disease

Sean Coffey et al.

Summary: Valvular heart disease (VHD) is a major cause of physical function loss, decreased quality of life, and shortened longevity. Rheumatic heart disease remains the most common manifestation of VHD globally, while calcific aortic stenosis and degenerative mitral valve disease are also significant. Despite improvements in mortality related to rheumatic heart disease, deaths from calcific aortic stenosis have increased over the past 20 years.

Comparison of NSGA-II, MOALO and MODA for Multi-Objective Optimization of Micro-Machining Processes

Milan Joshi et al.

Summary: The increasing popularity of micro-machining has led to widespread use of micro-turning and micro-milling in the manufacturing industry, where optimizing cutting parameters is crucial for performance but often presents conflicting objectives. This study utilizes metaheuristic multi-objective optimization algorithms to address this issue and compares the performance of NSGA-II, MOALO, and MODA in micro-machining applications by using the COPRAS method for assessing Pareto solutions.
