Fire-tower is effectively applied in forest fire prevention and commanding system, especially in fire monitor and position. After explaining the significance of scientific planning of fire-tower, this paper analyzes GIS`s functions in building forest fire prevention system. This paper uses case study method, which designs a model, fire tower planning and analysis, based on MapGIS platform. Afte...
Abstract The current fault location ways for the double-circuit transmission lines on same tower do not consider coupling relationship of lines. accuracy is low in practical application. Therefore, a method basing electromagnetic time reversal proposed this paper. six-sequence component used to transform line’s impedance matrix eliminate between line pole. positive and negative phase characteri...
Our goal is to study the pseudo-intersection and tower numbers on uncountable regular cardinals, whether these two cardinal characteristics are necessarily equal, related problems existence of gaps. First, we prove that either $\mathfrak p(\kap
Today, many small aerodromes struggle with financial difficulties, and a large cost is air traffic control. Remote tower centers, which remotely provide air traffic services to aerodromes, can help reduce this cost. Each center may contain a number of remote tower modules, where each module is manned by a controller that can handle one or more aerodromes. In this paper we present the remote tow...
The influence of the local terrestrial environment on nocturnal atmospheric CO2 measurements at a 329-m television transmitter tower (and a component of a CO2 monitoring network) was estimated with a tracer release experiment and a subsequent simulation of the releases. This was done to characterize the vertical transport of emissions from the surface to the uppermost tower level and how it is ...
On July 9, 2013, an outbreak of Legionnaires' disease (LD) was identified at Long-Term Care Facility A in central Ohio. This article describes the investigation of the outbreak and identification of the outbreak source, a cooling tower using an automated biocide delivery system. In total, 39 outbreak LD cases were identified; among these, six patients died. Water samples from a cooling tower we...
