A Monocular Ground Plane Estimation System [PDF]

Procedings of the British Machine Vision Conference 1991, 1991
This paper describes the design of a system for estimating the pose of a camera mounted on a vehicle which moves over a flat floor. The system has been designed to work in conjunction with an obstacle avoidance scheme. Measurements are derived from a sequence of images captured by a single camera rigidly mounted on the vehicle and looking at the floor,

A pulse generator with inductive energy storage for measuring the grounding resistance of transmission line towers

Vestnik MGTU, 2018
The pulse method may be used to measure the footing resistance of transmission towers with overhead grounding wires. Measuring systems that obtain the time dependent transient impedance may be used to measure the low-frequency resistance of transmission ...

Optimization of substation grounding grid design for horizontal and vertical multilayer and uniform soil condition using Simulated Annealing method.

PLoS ONE, 2021
Grounding systems are critical in safeguarding people and equipment from power system failures. A grounding system's principal goal is to offer the lowest impedance path for undesired fault current. Optimization of the grounding grid designs is important

Trinocular ground system to control UAVs [PDF]

2009 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2009
In this paper we introduce a real-time trinocular system to control rotary wing Unmanned Aerial Vehicles based on the 3D information extracted by cameras located on the ground. The algorithm is based on key features onboard the UAV to estimate the vehicle's position and orientation.

Acceptable risk zone for grounding systems in distribution MV/LV substations

, 2021
The paper concerns the analysis and simulation of the behavior of the total ground potential around the grounding systems of the installation-on-pole (PTP and disconnector) and MV/LV substations in order to define and quantify the best possible safety ...

Interconnections criteria of grounding grids in global grounding systems

, 2018
A Global Grounding System is defined as the combination of local grounding systems, obtained by their interconnection, which ensures, thanks to their proximity, that no dangerous touch voltages can arise.

How is meaning grounded in dictionary definitions?

, 2008
Meaning cannot be based on dictionary definitions all the way down: at some point the circularity of definitions must be broken in some way, by grounding the meanings of certain words in sensorimotor categories learned from experience or shaped by ...

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.
