For decades detection and monitoring of forest and other wildland fires has relied heavily on aircraft (and satellites). Technical advances and improved affordability of both sensors and sensor platforms promise to revolutionize the way aircraft detect, monitor and help suppress wildfires. Sensor systems like hyperspectral cameras, image intensifiers and thermal cameras that have previously bee...

When we find our way in the environment, we need to integrate information about location, direction and distance into a coherent map-like representation. Our work over the last 10 years has suggested that the medial entorhinal cortex plays a central role in this process. A key component of the entorhinal network for spatial mapping is the grid cell, which we discovered, together with our collea...

This work presents a new framework for three-dimensional modeling of dynamic fires present in unstructured scenes. The proposed approach addresses the problem of segmenting fire regions using information from YUV and RGB color spaces. Clustering is also used to extract salient points from a pair of stereo images. These points are then used to reconstruct 3D positions in the scene. A matching st...

This paper considers the problem of reconstructing visually realistic 3D models of fire from a very small set of simultaneous views (even two). By modeling fire as a semi-transparent 3D density field, we show that fire reconstruction is equivalent to a severely under-constrained computerized tomography problem, for which traditional methods break down. Our approach is based on the observation t...

There is uncertainty about average and peak levels of radioactivity to which some people are being exposed. Radioactive materials cause harm only when not enough antioxidants are present to soak up the extra electrons (energetic free radicals; oxidative stressors) induced by radioactive particles. Radiation is like a submolecular fire. There is a temperature above which even the best fire resis...

When Ca2+ is released from internal stores in living cells, the resulting wave of increased concentration can travel without deformation (continuous propagation) or with burst-like behavior (saltatory propagation). We analyze the "fire-diffuse-fire" model in order to illuminate the differences between these two modes of propagation. We show that the Ca2+ release wave in immature Xenopus oocytes...

The effects of a small fire event at a nuclear power plant can disrupt the supply of electricity to many thousands of customers and loss of feed-in tariffs to the operator. The consequences of a serious fire that causes core damage can affect the health and welfare of millions, perhaps generations of citizens and the environment. Clearly the stakes are very high. Nothing defines 'mission-critic...
