Positively and Negatively Round Turbulent Buoyant Jets into Homogeneous Calm Ambient

open access: yesProceedings, 2018
A mathematical model has been employed to determine the characteristics of Boussinesq round buoyant jets which are injected horizontally or at an angle to horizontal, into a homogeneous, calm ambient.

Impact Points and Their Effect on Trajectory in Soccer

open access: yesProceedings, 2018
The kick skill and its analysis are important in Soccer. To detect impact point by using virtual impact model is aim of this study. The virtual impact model was made as a surface composed of virtual markers.

On Adversarial Robustness of Trajectory Prediction for Autonomous Vehicles [PDF]

open access: yesComputer Vision and Pattern Recognition, 2022
Trajectory prediction is a critical component for autonomous vehicles (AVs) to perform safe planning and navigation. However, few studies have analyzed the adversarial robustness of trajectory prediction or investigated whether the worst-case prediction ...

Detection of odor sources and high concentrations of pollutants in the Ore Mountains by modeling of air mass paths

open access: yesMeteorologische Zeitschrift, 2013
Since decades odor pollutions are a well-known problem in the Ore Mountains and Vogtland, especially areas close to the border to the Czech Republic. Many facilities in North Bohemia are considered as the main polluters. Most notably these contaminations

The Trajectory of Targets and Critical Lures in the Deese/Roediger–McDermott Paradigm: A Systematic Review

open access: yesFrontiers in Psychology, 2021
The Deese/Roediger–McDermott (DRM) paradigm has been used extensively to examine false memory. During the study session, participants learn lists of semantically related items (e.g., pillow, blanket, tired, bed), referred to as targets.

Trajectory-Based 3D Point Cloud ROI Determination Methods for Autonomous Mobile Robot

open access: yesIEEE Access, 2023
With depth cameras and LiDAR improving and generating more data, their applications in 3D point clouds are growing rapidly. However, the vast amount of generated data increases the computational load and results in a shortage of storage space. Therefore,

Trajectory: A model of the sign and of semiosis

open access: yesSign Systems Studies, 2020
This paper examines how far the model of the trajectory as a path that a moving object follows from a source to a goal is an adequate model of the sign and of semiotic processes.

Brachial-ankle pulse wave velocity trajectories in a middle-aged population

open access: yesFrontiers in Cardiovascular Medicine, 2023
ObjectiveThe “trajectory” phenotype was observed in several cardiovascular risk factors with aging. We aim to identify multiple brachial-ankle Pulse Wave Velocity (baPWV) trajectory phenotypes and assess their determinants.MethodsAmong 5,182 participants

Itinéraire d’un blogueur : entre quête de reconnaissance et visibilité limitée

open access: yesItinéraires, 2010
Blogs are known to have facilitated the access of Internet users to online publication. Nevertheless, behind this comparatively technical simplicity, the practice of blogging appears to be fraught with many traps. Through the trajectory of a blogger, our
