With the rapid development of urbanization, fire risk factors have increased greatly, indicating a higher requirement for urban firefighting security. Fire rescue capabilities can be effectively improved by scientific layout stations, and therefore, optimal spatial arrangement stations has practical implications safety. In this paper, method planning locations is presented, taking into account ...

This paper analyzes a linear feature covering problem (LFCP) with distance constraints, and characterizes the problem by a fuzzy multi-objective (MO) optimization model. An integrated approach combining an Ant algorithm (LFCP-Ant) and a Geographic Information System (GIS) has been devised to solve the LFCP problem in large scale. The efficacy of the proposed approach is demonstrated using a cas...

SMS had been demonstrated only two years previously; and the first Bluetooth specification would not arrive for another three years. Regrettably, we were forced to remove one of our FLUMP stations from a public area after a short time because of fire safety concerns—our first hint that deployment “in the wild” brought its own unique set of challenges. From those challenges, we learned many less...

This paper describes an application of real time data capture and wireless transmission of meteorological data used by agricultural administrators to support operational decisions such as irrigation scheduling and pesticide application. Forestry companies need such information for managing operations during the fire season. The system architecture based on distributed wireless data communicatio...

Distance to the kth nearest facility is important when facilities are closed Emergency facilities !! Hospitals !! Fire stations !! Refuges Facilities are closed because of accidents and disasters Analytical expressions for the kth nearest distance have been obtained Grid Random Grid Random For finding the relationship between the distances, we need the joint distribution Distribution of the kth...

Subways are an important means of transport and stations can be filled with thousands of passengers at a time and have limited space for movement. In emergencies such as fire, the life of passengers is at high risk. But not only spatial restrictions of escape routes, also passenger characteristics are important. Subway passengers differ widely in their motivation and individual behavior. In thi...

A synthesis was carried out to examine Alaska’s boreal forest fire regime. During the 2000s, an average of 767 000 ha!year–1 burned, 50% higher than in any previous decade since the 1940s. Over the past 60 years, there was a decrease in the number of lightning-ignited fires, an increase in extreme lightning-ignited fire events, an increase in humanignited fires, and a decrease in the number of ...

Dendroecological techniques were applied to reconstruct stand-replacing fire history in upper montane forests in northern New Mexico and southern Colorado. Fourteen stand-replacing fires were dated to 8 unique fire years (1842– 1901) using four lines of evidence at each of 12 sites within the upper Rio Grande Basin. The four lines of evidence were (i) quaking aspen (Populus tremuloides Michx.) ...
