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

open access: yesVestnik 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 ...

A Monocular Ground Plane Estimation System [PDF]

open access: yesProcedings 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,

Arbitrary Grounding [PDF]

open access: yes, 2021
The aim of this paper is to introduce, elucidate and defend the usefulness of a variant of grounding, or metaphysical explanation, that has the feature that the grounds explain of some states of affairs that one of them obtains without explaining which ...

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

open access: yesPLoS 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]

open access: yes2009 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.

Identity criteria: an epistemic path to conceptual grounding

open access: yes, 2018
Are identity criteria grounding principles? A prima facie answer to this question is positive. Specifically, two-level identity criteria can be taken as principles related to issues of identity among objects of a given kind compared with objects of a ...
