Performance of the recursive methods applied to compute the transient responses on grounding systems
(2021-07-01)
Ground Potential Rise (GPR) is an important factor for a grounding system that must be properly designed to protect people against any dangerous induced voltages and to avoid damages in equipment. In this context, several ...
Current uses of ground penetrating radar in groundwater-dependent ecosystems research
(Elsevier B.V., 2017)
A Grounding System Model Directly in Time-Domain
(2016-10-01)
This work presents a technique for electrical grounding system representation, directly in the time domain. It is based on the theory of least squares and starts from harmonic grounding impedance, representing it by discrete ...
A Portable Ground-Truth System Based on a Laser Sensor
(Springer-Verlag, 2012)
State estimation is of crucial importance to mobile robotics
since it determines in a great measure its ability to model the world from
noisy observations. In order to quantitatively evaluate state-estimation
methods, ...
Computing Tower-Footing Grounding Impedance and GPR curves of Grounding Electrodes Buried in Multilayer Soils
(Ieee, 2019-01-01)
Grounding systems are essential to dissipate fault currents into soil to guarantee safe conditions to personnel and equipment. In this context, several approaches have been employed to calculate tower-footing grounding ...

(2019-09-01)
Grounding systems are essential to dissipate fault currents into soil to guarantee safe conditions to personnel and equipment. In this context, several approaches have been employed to calculate tower-footing grounding ...
GROUND STATE AND NON-GROUND STATE SOLUTIONS OF SOME STRONGLY COUPLED ELLIPTIC SYSTEMS
(AMER MATHEMATICAL SOCPROVIDENCE, 2012)
We study an elliptic system of the form Lu = vertical bar v vertical bar(p-1) v and Lv = vertical bar u vertical bar(q-1) u in Omega with homogeneous Dirichlet boundary condition, where Lu := -Delta u in the case of a ...
Fine-scale root community structure and below-ground responses to grazing show independence from above-ground patterns
(Wiley Blackwell Publishing, Inc, 2017-11)
Question: Root biomass distribution and below-ground processes are the main drivers of plant community structure and dynamics in arid rangelands. However, despite their relevance, below-ground plant responses to disturbance ...
Using circuit elements to represent the distributed parameters of a grounding system under lightning strokes
(2019-07-01)
This work presents a proposal to represent electrical grounding systems directly in the time domain. The advantage in using this type of representation is that voltage and current are better understood in this domain, and ...
Application of neural networks to identify features of dynamical grounding systems
(Institute of Electrical and Electronics Engineers (IEEE), 2001-01-01)
The accurate identification of features of dynamical grounding systems are extremely important to define the operational safety and proper functioning of electric power systems. Several experimental tests and theoretical ...
