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 ...

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.

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

open access: yesTherapeutic 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.

Fault location method combining transient mutation and dynamic time warping algorithm for grounding system

open access: yesEnergy Reports, 2023
In the urban distribution network, due to the wide application of underground cables, the traditional resonant grounding system has gradually been unable to match the increasing fault current amplitude, real-time compensation and harmonic component ...

Senescent ground tree rewrite systems [PDF]

open access: yesProceedings of the Joint Meeting of the Twenty-Third EACSL Annual Conference on Computer Science Logic (CSL) and the Twenty-Ninth Annual ACM/IEEE Symposium on Logic in Computer Science (LICS), 2014
Ground Tree Rewrite Systems with State are known to have an undecidable control state reachability problem. Taking inspiration from the recent introduction of scope-bounded multi-stack pushdown systems, we define Senescent Ground Tree Rewrite Systems. These are a restriction of ground tree rewrite systems with state such that nodes of the tree may no ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

A Method for Calculating Grounding Resistance of Reinforced Concrete Foundation Grounding Systems

open access: yesEnergies, 2022
Tower foundations have been used as grounding electrodes to reduce the area of the grounding devices. However, it is difficult to calculate the grounding resistance due to the complex structure of the reinforced concrete foundation.
