BACKGROUND More needs to be known about the prevalence of risk and protective factors for fires, burns, and carbon monoxide poisoning in U.S. households. METHODS A random-digit-dial survey was conducted about home safety with 1003 respondents representing households in the continental United States. Descriptive statistics assess the prevalence of risk and protective factors for fires, burns, ...

This review brings together several different strands of research: (i) The sleep arousal literature pertaining to auditory arousal thresholds (AAT), (ii) studies on factors affecting responsiveness to auditory signals during sleep, (iii) literature on responsiveness to smoke detector alarms during sleep and (iv) research on fire fatality statistics and victim characteristics. The review discuss...

Historical buildings often fail to meet today’s building and fire protection regulations due their structure space restrictions. For this reason, if such encounter fire, serious damage will be resulted. The of the Notre-Dame Cathedral in Paris (Notre-Dame de Paris) April 2019 highlights seriousness problem. In study, historical “Tamsui Church” was selected as an example. Fire Dynamics Simulator...

this study was conducted to investigate the effects of applying methods andamount of ammonium polyphosphate (0, 2 and 4 wt%) on fire retardancy andmechanical properties of wood flour/polypropylene composites. the resultsshowed that addition of fire retardant improved the mechanical properties such astensile and flexural strengths and fire retardancy of composites. but by increasingof fire retar...

Forest fire in recent years has paid great attention to climate change and ecosystems. Remote sensing is a quick and inexpensive way to detect and monitor forest fires on a large scale. The purpose of this study was to identify forest and rangeland fire hazards using NOAA / AVHRR in Kayamaki Wildlife Refuge. For the purpose of this study, the history of the fire-burns occurred in MODIS products...

Several researchers have been drawn to the development of fire detector in recent years, protect people and property from catastrophic disaster fire. However, studies related monitoring are affected by some unique characteristics sensor signals, such as time dependence complexity signal pattern based on variety types,. In this study, a new deep learning-based approach that accurately classifies...

Currently, neural network methods of fire detection have been used to monitor fires in forests. To date, such systems developed as the Prometheus project, Fire Video Detector, and Artificial Intelligence University method. These make it possible determine a with an accuracy more than 90 %, for which combination recurrent light-line networks is used. The article proposes method improving efficie...
