Steel Grounding Design Guide and Application Notes

Based on the National Bureau of Standards [presently called The National Institute of Standards and Technology or “NIST”] statistical data on corrosion of steel, an equation is introduced to estimate the corrosion rate of underground steel. The variables include the major soil characteristics (parameters), namely: resistivity, pH value, moisture content and aeration. This formula, together with...

A New Method of Grounding Grid Design

In order to equalize the electric potential distribution of the grounding grid surface, and improve the safety level of the grounding grid, method for optimal arrangement of conducts in the grounding grid is proposed in this paper. The calculation results about maximum touch voltages and mesh potentials show that the method can reduce touch voltage and equilibrium surface potential. It is shown...

Symbol Grounding Revisited 1 the Origin of Symbol Grounding 1.1 Overview 1.2 the Symbol Grounding Problem

Symbol Grounding has originated in the domain of cognitive connectionism as an approach to a model of language acquisition.It has, however, transcended this restricted domain and its most prominent proponents now regard it as a technique which is of general importance to the connectionist-symbolic debate, especially for their integration into a common framework. This paper revisits the claims m...

Signal transmission model for the substations grounding grid

The signal of the wireless sensor network in Grounding grid, owing to energy loss, network congestion, path constraints and other factors, is easy to delay even partially losing. In order to ensure that the signal can be transmitted effectively in grounding grids for the substation, this paper presents a method based on traffic model of back-off balanced multiple sensor network cooperation mode...

Ontology Grounding

An ontology is a structured semantic model, composed of concepts, relations and instances. Data is a more primitive but concrete assembly of instances described by their attributes. An example of topic ontology is Open Directory of Web documents used in Google organizing documents into topics and subtopics, such as “Science”, “Arts”, etc. However, many ontologies are originally manually develop...
