FIRE DETECTION ALGORITHMS USING MULTIMODAL SIGNAL AND IMAGE ANALYSIS Behçet Uğur Töreyin Ph.D. in Electrical and Electronics Engineering Supervisor: Prof. Dr. A. Enis Çetin January, 2009 Dynamic textures are common in natural scenes. Examples of dynamic textures in video include fire, smoke, clouds, volatile organic compound (VOC) plumes in infra-red (IR) videos, trees in the wind, sea and ocea...

Authors Abstract As part of a Joint Fire Science Program project, a team of social scientists reviewed existing fire social science literature to develop a targeted synthesis of scientific knowledge on the following questions: 1. What is the public's understanding of fire's role in the ecosystem? 2. Who are trusted sources of information about fire? 3. What are the public's views of fuels reduc...

The state of Alabama has one of the highest fire-related fatality rates in the nation. The goal of this study was to present the epidemiology of fire-related deaths in the state of Alabama. Fatality reports for all fire-related deaths in the state of Alabama from 1992 to 1997 were obtained from the State Fire Marshall's Office. Fatality rates were calculated and compared according to age, sex, ...

BACKGROUND An evaluation of a smoke-free home initiative launched in Rotherham, northern England, in July 2009. METHODS Two approaches were used: (i) a postal survey of participants 4 months after signing up as a SFH and (ii) a telephone consultation. The survey was sent to 620 households (of 654 who signed up to the scheme); 289 (46.6%) were returned. The telephone consultation involved 20 h...

The relationship between heat release rate and other fire reaction properties of fibre reinforced polymer composite materials is investigated. The heat release rate and fire reaction properties of thermoset matrix composites reinforced with combustible fibres (aramid, extended-chain polyethylene) or non-combustible fibres (glass, carbon) were determined over a range of heat flux levels using th...

This study investigates the fire safety problem of a smoke detection system in terms of the probable response of light scattering photoelectric smoke detectors. In particular, response characteristics of the smoke detectors were studied experimentally in a test chamber described in UL268, with cotton wick generated fire smoke flowing at a velocity between of 0.5 ms and 3 ms. Measurements of a ‘...

[1] We use a plume height climatology derived from space-based Multiangle Imaging Spectroradiometer (MISR) observations to evaluate the performance of a widely used plume-rise model. We initialize the model with assimilated meteorological fields from the NASA Goddard Earth Observing System and estimated fuel moisture content at the location and time of the MISR measurements. Fire properties tha...

The Iowa City Landfill in eastern Iowa, United States, experienced a fire lasting 18 days in 2012, in which a drainage layer of over 1 million shredded tires burned, generating smoke that impacted the surrounding metropolitan area of 130,000 people. This emergency required air monitoring, risk assessment, dispersion modeling, and public notification. This paper quantifies the impact of the fire...

Enclosed-space smoke inhalation is the fifth most common cause of all unintentional injury deaths in the United States. Increasingly, cyanide has been recognized as a significant toxicant in many cases of smoke inhalation. However, it cannot be emergently verified. Failure to recognize the possibility of cyanide toxicity may result in inadequate treatment. Findings suggestive cyanide toxicity i...
