We combine a scenario-based, standard-response optimizationmodel with stochastic simulation to improve the efficiency of resource deployment for initial attack on wildland fires in three planning units in California. The optimization model minimizes the expected number of fires that do not receive a standard response — defined as the number of resources by type that must arrive at the fire with...

This study sought to evaluate the utility of radar derived rainfall data as a unique resource for analysing the interplay between rainfall and ecosystem dynamics in the Kimberley region of Western Australia. The Bureau of Meteorology’s Weather Watch radar network was investigated as a potential source of spatially explicit radar data that could be processed to create estimates of accumulated ra...

INTRODUCTION Underground stations can broadly be divided into two methods of construction: cut and cover (i.e. excavating a trench and recovering) and tunnelling. The station layout is mostly comprised of the areas that are common to all stations and their spatial planning must be set out with a thorough understanding of passenger circulation patterns. The station components, namely the ticket ...

We provide efficient algorithms for two major problems in network analysis. One is the Graph Center (GC) problem and the other is the Graph Bottleneck (GB) problem. The GC problem is relevant for facility location, while the GB problem is relevant for transportation and logistics. The GC problem is to identify a pre-determined number of center vertices such that the distances or costs from (or ...

Indonesia’s fire and haze problem is reviewed, and a model quantifying the relationship between drought and haze from biomass burning in western Indonesia is presented. Visibility observations from weather stations in Sumatra and Kalimantan were used as a haze indicator. The Drought Code component of the Canadian Forest Fire Weather Index System was used as a drought indicator. Using meteorolog...

In a large earthquake, rescue operations and fire-fighting are obstructed by firespreading and street-blockages. Therefore, it is important to quickly collect and utilize disaster information for disaster mitigation. In this paper, firstly, we develop a Web application for posting and viewing information collected by users in real time. Using this system, it is possible not only to easily share...

BACKGROUND Recent epidemiological research on firefighters indicates an increased incidence of specific types of cancer. Intervention is needed in the fire service yet little is known about how firefighters perceive their cancer risk. METHODS Participant observation (150 h, n = 100) and focus group (n = 17) data were collected from 15 fire stations in South Florida. Firefighters had at least ...
