Open-jet, hard-wall, and hybrid test section configurations are typically used in wind tunnel tests, aiming to represent the ideal free-flight condition. Each type requires special adaptations of experimental hardware specific correction methodologies that account for systematic measurement errors. Differently from previous research, this paper investigates comparability measurements performed ...

Lattice Boltzmann simulations were carried out to investigate the noise mitigation mechanisms of a 3-D printed porous trailing-edge insert, elucidating link between reduction and material permeability. The insert is based on unit cell resembling lattice diamond atoms. It replaces last 20 % chord NACA 0018 at zero angle-of-attack. A partially blocked considered by adding solid partition 84 96 ae...

We examine the long-run behavior of multiagent online learning in games that evolve over time. Specifically, we focus on a wide class policies based mirror descent, and show induced sequence play (a) converges to Nash equilibrium time-varying stabilize long run strictly monotone limit, (b) it stays asymptotically close evolving stage (assuming they are strongly monotone). Our results apply both...

This work discusses the experimental challenges and processing of unsteady experiments for a pitching wing in low-speed wind tunnel Vrije Universiteit Brussel. The setup used consisted two independent devices: (a) position control device to steer pitch angle wing, (b) pressure measurement measure aerodynamic loads. can range frequencies, amplitude, offset levels. In this work, NACA-0018 profile...

Objectives To investigate neuroanatomic volume differences in tinnitus and hearing loss. Study Design Cross‐sectional. Methods Sixteen regions of interest (ROIs) adults (43 male, 29 female) were examined using 3Tesla structural magnetic resonance imaging four cohorts: 1) with moderate loss (N = 31), 2) only 15), 3) normal 17), 4) 13). ROI volumes corrected for brain size, age, sex variations. A...

A symmetrical NACA 0018 airfoil is often used in such applications as small-to-medium scale vertical-axis wind turbines and aerial vehicles. review of the literature indicates a large gap experimental studies this at low moderate Reynolds numbers previous century. This has limited potential development classical turbulence models, which range predict lift coefficients with insufficiently accura...

Background: There are large populations of people who affected by malaria. In 2004, it has been reported that there were 350–500 million cases the illness worldwide. More than two billion people, or more 40% world's population, at risk developing malaria, and an estimated 1.1-1.3 deaths from malaria globally each year, according to WHO report. The objectives current study is find out prevalence...
