NUMERICAL SIMULATION OF AIRFLOW AROUND VEHICLE MODELS

Vietnam Journal of Science and Technology, 2018
This article carries out the numerical simulation of airflow over three dimensional car models using ANSYS Fluent software. The calculations have been performed by using realizable k-e turbulence model. The external airflow field of the simplified BMV M6 model with or without a wing is simulated.

Calculation of locomotive traction force in transient rolling contact

Applied and Computational Mechanics, 2017
To represent thewheel-rail contact in numerical simulations of rail vehicles, simplified models (Fastsim, Pola´ch etc.) are usually employed. These models are designed for steady rolling only, which is perfectly suitable in many cases.

Numerical Simulation for Vehicle Powertrain Development

, 2011
Ground transportation industry has accepted the reality that fast, efficient, and cost effective engine and vehicle development necessitates the use of numerical simulation at every stage of the design process. Within the vehicle powertrain design and development process, three different levels of modelling can generally be found: 1. Detailed modelling:

In vitro and in silico modelling of ROS1‐positive non‐small cell lung cancer reveals fusion‐dependent tyrosine kinase inhibitor responses

Molecular Oncology, EarlyView.
Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.

Speed Dependent Gain Scheduled LQI based Path Following Control System Design for Automated Vehicles

Gazi Üniversitesi Fen Bilimleri Dergisi, 2019
Automated path following is one of the major problem in automated vehicle control. Automated vehicle should follow the desired path to minimize the lateral deviation from the path while traveling at the desired speed. In this paper, LQI control method is

Mutant p53R273H disrupts PDPK1 homodimerization and contributes to PDPK1 activation

Molecular Oncology, EarlyView.
How mutant p53R273H drives AKT signaling is unclear. We show that p53R273H, but not wild‐type, directly binds PDPK1 via a mutation‐dependent conformational change. This interaction disrupts inhibitory PDPK1 homodimerization and enhances AKT phosphorylation.
