Obstacle Course Training Helps Athletes Develop Foundations for All Sports（图）
Training Youth Athletes OCR
2024/12/13
Obstacle Course Racing (OCR) has garnered a reputation for being a rather grueling event to partake. Take one of the most popular organizations, Spartan Race, and one will notice that it is geared tow...
CHALLENGES WITH OBSTACLE DATA FOR MANNED AND UNMANNED AVIATION
Obstacle data UTM U-Space Aircraft Drones Personal air vehicles
2018/11/9
The objective of this paper is to raise awareness about the significance of collecting and ensuring the quality of the obstacle data required for the safety of air navigation for both manned and unman...
INDOOR NAVIGATION FROM POINT CLOUDS: 3D MODELLING AND OBSTACLE DETECTION
indoor modelling laser scanner automation path planning obstacles real navigation
2016/11/8
In the recent years, indoor modelling and navigation has become a research of interest because many stakeholders require navigation assistance in various application scenarios. The navigational assist...
APPLICATION OF DSM IN OBSTACLE CLEARANCE SURVEYING OF AERODROME
Obstacle Clearance Surveying Obstacle Limitation Surface Digital Surface Model
2016/7/8
Compared to the wide use of digital elevation model (DEM), digital surface model (DSM) receives less attention because that it is composed by not only terrain surface, but also vegetations and man-mad...
Random Homogenization of Fractional Obstacle Problems
Random Homogenization Fractional Obstacle Problems
2015/10/15
We use a characterization of the fractional Laplacian as a Dirichlet to Neumann operator for an appropriate differential equation to study its obstacle problem in perforated domains.
We study the homogenization of an obstacle problem in a perforated domain, when the holes are periodically distributed and have random shape and size. The main assumption concerns the capacity of the ...

Čerenkov-like radiation in a binary superfluid flow past an obstacle
Coupling condensate dark soliton whirlpool rotating vortex dipole
2014/12/25
We consider the dynamics of two coupled miscible Bose-Einstein condensates, when an obstacle is dragged through them. The existence of two different speeds of sound provides the possibility for three ...

Spinor bose-einstein condensate macroscopic nonlinear structure vortex ring
2014/12/24
We study the flow of a spinor (F=1) Bose-Einstein condensate in the presence of an obstacle. We consider the cases of ferromagnetic and polar spin-dependent interactions, and find that the system demo...
