Abstract Fire throttling is the increase in flow resistance due to a large fire longitudinally ventilated tunnel. Although effect has been known and studied for tunnels over last 40 years, there not yet consistent one-dimensional (1D) model that can describe this behaviour or framework suitable practical application. We propose semi-empirical model, based upon pipe engineering principles, by se...

Fire risk is perhaps the most common in category of special emergencies, being a phenomenon that affects important areas economic and social life, such as buildings, industrial facilities, public spaces, forests, crops, or transportation. Scientific investigation fires constituted set organized actions, technical nature, undertaken to determine causes led occurrence fires, source ignition, circ...

In ventilated tunnel fires, smoke and hot combustion products may form a layer near the ceiling and flow in the direction opposite to the ventilation stream. The existence of this reverse stratified flow has an important bearing on fire fighting and evacuation of underground mine roadways, tunnels and building corridors. In the present study, conducted by the National Institute for Occupational...

Solving sequential decision making problems in computational sustainability often requires simulators of ecology, weather, fire, or other complex phenomena. The extreme computational expense of these simulators stymie optimization and interactive visualization of decision rules (policies). This work presents our results in creating an interactive visualization for a wildfire management problem ...

Film dosage forms (FDs) containing miconazole (MCZ) for the treatment of oral candidiasis were prepared using water-soluble polysaccharides, and the dissolution profiles of MCZ from the FDs were investigated. In addition, the forms were modified by the addition of a surface active agent to accelerate the drug dissolution rate. Circular films incorporating MCZ were obtained using each polysaccha...

In this paper we introduce a wildfire simulation model. This is a sample of the possible integration between a discrete event simulator (like LeanSim®, developed by Computing Laboratory of the Barcelona School of Informatics), and a Virtual GIS (like VirtualLands©, developed by Gea4D), in a model that represents the fire propagation in a landscape defined in the GIS (the structure) and in the s...

NEST is a simulator for networks of point neurons, that is, neuron models that collapse the morphology (geometry) of dendrites, axons, and somata into either a single compartment or a small number of compartments (Gewaltig and Diesmann, 2007). This simplification is useful for questions about the dynamics of large neuronal networks with complex connectivity. In this text, we give a practical in...

Film dosage forms (FDs) containing allopurinol (AP) were prepared using a casting method with water-soluble polysaccharides, such as sodium alginate (ALG), and the release profile of AP from FDs was investigated in limited dissolution medium. Some ALGs were able to form FDs incorporating AP, and the thickness was about 50 μm. All FDs were easy to handle, though the rheological properties varied...
