Using lightweight fire-rated board (LFRB) presents cost-effective opportunities for various passive fire protection measures. The aim of the project is to develop an LFRB with enhanced resistance, acoustic properties, and mechanical properties. These properties were determined using a Bunsen burner, furnace, energy-dispersive X-ray, impedance tube instrument, Instron universal testing machine. ...

We solve the correspondence problem with integrate and fire models. Taking into account the requirement for rapid processing, we use a spike timing code, associated with receptive fields and Winner Takes all Strategy. We study through computer experiments the properties and performance of various shapes of receptive fields. We use a perfect Integrate and Fire model, and we study the interest of...

As an important new flame retardant, zinc stannate (ZS) shows wide application prospects due to its many advantages. However, the retardant mechanism of composites made with polymer combined ZS is still unclear. In particular, there a lack molecular level description micro-scale mechanism. The combustion through simulation technology has become research paradigm in field fire, which can provide...

The Atlanta Fire Rescue Department (AFRD) attempts to reduce fire risk by inspecting buildings for potential hazards and fire code violations. This paper provides a case study exemplifying how data science can be used to help cities identify and prioritize potential property inspections, using machine learning, geocoding, and information visualization. As a result of this work, we generated a r...

A review of the current situation and development of fire safety design for steel structures in China is given in this paper. Several codes and specifications used for fire safety design in China are introduced, and the present design methods are summarized. Then some research achievements on the behavior of steel structures at elevated temperature are presented. The achievements include materi...

Polarization measurements have become nearly indispensible in lidar cloud and aerosol studies. Despite polarization's widespread use in lidar, its theoretical description has been widely varying in accuracy and completeness. Incomplete polarization lidar descriptions invariably result in poor accountability for scatterer properties and instrument effects, reducing data accuracy and disallowing ...

Forest fire models have been widely studied from the context of self-organized criticality and from the ecological properties of the forest and combustion. On the other hand, reaction-diffusion equations have interesting applications in biology and physics. We propose here a model for fire propagation in a forest by using hyperbolic reaction-diffusion equations. The dynamical and thermodynamica...

We derive and study two-dimensional generalizations of integrate-and-fire models which can be found from a piecewise linear idealization of the FitzHugh-Nagumo or Morris-Lecar model. These models give rise to new properties not present in one-dimensional integrate-and-fire models. A detailed analytical study of the models is presented. In particular, (i) for the piecewise linear FitzHugh-Nagumo...

The aim of this paper is to present some improvements in the metrology of forest fire flames by coupling image processing and radiative heat flux measurement. A new metrological tool using a visual video camera and a specific multiple thermal sensor is proposed. By means of an appropriate segmentation algorithm and the Direct Linear Transformation, the image processing methodology gives the for...
